Description

PORTABLE BREAST PUMP SYSTEM AND COMPONENTS AND USES THEREOF
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of and priority to U.S. Provisional Patent Application No. 63/535,680, filed on August 31, 2023, and U.S. Provisional Patent Application No. 63/535,692, filed on August 31, 2023, each of which is incorporated herein by reference in its entirety.
BACKGROUND
New mothers use breast pumps post-partum in order to accomplish milk feeding and milk expression. Breast pumps systems draw breast milk from a breast of a user and may be used to pump breast milk for later consumption by an infant, to stimulate lactation in users with low milk supply, or to relieve engorgement. Breast pumps may be manually operated, for example by squeezing a handle or operation of a foot pedal. Breast pumps may also be electrically driven by a drive unit.
On average, new mothers feed their infants more than 12 times per day, with newborn infants often needing to be fed every two to three hours. Mothers or other care providers may spend more than four hours each day breastfeeding, on average spending 20 minutes out of every two hours breastfeeding, interrupting work, social, and sleep schedules.
SUMMARY
Traditional breast pumps demand mothers to be stationary and near an outlet to draw the power required to fully express the mother’s milk. Consequently, portable breast pumps are often less powerful and are unable to fully express all the milk in the breast. Not fully emptying breasts during pumping sessions can contribute to reduced milk supply and clogged milk ducts, leading to mastitis.
Commercially available portable breast pumps also include on-body milk collection, which requires a user to remove the breast cups in order to access the milk, and many of these pumps also have a large breast cup and/or milk collection profile. Breast cup removal and large breast cup profiles do not allow for discreet public pumping. Thus, there is a need for discreet, wearable, portable breast pump systems that provide all the power and benefits of traditional breast pumps, and permit access to pumped milk without necessitating breast cup removal, while allowing the user the mobility to pump while navigating daily activities, resting, sleeping, or traveling.
The present disclosure provides improved portable breast pumps, components thereof, and methods of use thereof that address these and other problems of traditional breast pumps.

DETAILED DESCRIPTION
The present disclosure provides improved portable breast pump systems, components thereof, e.g., a portable pump unit, and methods of use thereof. The present portable breast pump systems are particularly advantageous for navigating daily activities, discreet public pumping, access to pumped milk without removal of the breast cups, and traveling.
Portable Breast Pump System
The present disclosure provides an improved portable breast pump system 1. The portable breast pump system 1 is advantageous in that it allows for maximum mobility during pumping without the need for a power outlet; provides for discreet public pumping without necessitating removal of the breast cup 2 to remove milk after pumping; allows for pumping without assembly at the time of use; and/or allows for the collection and storage of milk for extended periods of time, e.g., while the mother is traveling outside the home. An exemplary system is shown in FIG. 3.
The portable breast pump system 1 may include at least one breast cup 2 in fluidic communication with a pressure source 9 and a reservoir 3 housed in a portable pump unit 6.
As shown in, e.g., FIG. 4, the portable breast pump system 1 can include a breast cup 2 having a housing (including upper housing 17 and a lower housing or milk chamber wall 26), a breast shield 19, and a diaphragm 18 disposed between the housing and the breast shield 19. The diaphragm 18 can separate a pressure chamber 20 from a milk chamber 21. The diaphragm provides numerous advantages including improved breast pumping in reclined positions. A pressure source 9 (e.g., negative pressure source and/or a positive pressure source) can be in fluidic communication with the pressure chamber 20, and the reservoir 3 can be in fluidic communication with the milk chamber 21.
The portable breast pump system 1 can include a food contact substance, e.g., for surfaces that contact milk and the breast. Alternatively, or in addition, the breast pump system 1 can include an infant grade material.
The portable breast pump system 1, including any element therein, can include a polymer (e.g., polyvinyl chloride (PVC), polyethylene terephthalate (PET), polypropylene (PP), polytetrafluoroethylene (PTFE), polyethylene, high-density polyethylene (HDPE), low-density polyethylene (LDPE), copolyester (e.g., Tritan EX401, polystyrene, a thermoplastic elastomer, thermoplastic polyurethane, nylon, polyvinylidene fluoride (PVDF), silicone, or polycarbonate (PC)), or any combination thereof. For example, the reservoir 3, the reservoir enclosure 4, the fluid conduit 5, or the breast cup 2, including the housing (including upper housing 17 and the lower housing or milk chamber wall 26), breast shield 19, and diaphragm 18 can include a polymer.
In some embodiments, portable breast pump system 1 can include a fabric (e.g., polyester, cotton, linen, satin, organdy, rayon, taffeta, broad cloth, poplin, velour, gauze, canvas, shirting, muslin, tweed, georgette, crepe, wool, twill, gabardine, denim, or drill). For example, the reservoir 3, the reservoir enclosure 4, or the breast cup 2, including the housing and the breast shield 19, can include a fabric or combination of fabrics.

In some embodiments, the negative pressure source is the same as the positive pressure source. In some embodiments, the pressure source 9, control valve 10, and/or power source 12 are located in a physically and/or thermally distinct compartment of the pump unit 6. The pump unit 6 may be portable such that a subject can carry the pump unit 6 on the body before, during, and/or after a pumping session.
The pump unit 6 may be configured to be releasably attached to a reservoir 3. In some embodiments, the pump unit 6 may be releasably attached to the reservoir 3 via internal and/or external threads, a catch mechanism, a magnet, snap fit, or other appropriate attachment mechanism. The pump unit 6 may include a reservoir enclosure 4. In some embodiments, the pump unit 6 includes a lid, and the reservoir enclosure 4 may be accessible through the lid. In some embodiments, the pump unit 6 does not include a lid to access the reservoir enclosure 4. In some embodiments, a reservoir 3 is releasably secured in the reservoir enclosure 4 such that the reservoir 3 does not unintentionally separate from the pump unit 6. In some embodiments, the reservoir enclosure includes a cooling element and/or insulation. For example, the reservoir enclosure 4 may be physically and/or thermally separated from another compartment in the pump unit 6, e.g., a compartment for the pressure source 9 and/or the power source. In some embodiments the reservoir enclosure 4 includes one or more sensors including one or more of a weight sensor, a load cell, a temperature sensor, a pressure sensor, an optical sensor, a flow sensor, a volume sensor, a pH sensor, and a viscosity sensor.

Pressure Source
The portable breast pump system 1 includes a pressure source 9 (e.g., a negative pressure source and/or a positive pressure source). Specifically, the pressure source 9 is configured to be used to move fluids, such as air, water, milk, and/or cleaning fluid, in the portable breast pump system 1. In some embodiments, the portable breast pump system 1 includes a plurality of pressure sources (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10). In some embodiments, at least one pressure source is a peristaltic pump. In some embodiments, at least one pressure source is a vacuum pump, e.g., which is capable of producing negative and positive pressure.
In some embodiments, the portable breast pump system 1 includes a negative pressure source that provides negative pressure to the breast cup 2, and thus the nipple of the breast in order to express milk. Additionally, the negative pressure source may be configured transport milk in the portable breast pump system 1, e.g., to expand and/or compress a pressure chamber 20 and/or milk chamber 21 in specific breast cups. In some embodiments, the negative pressure source may be configured to provide pressure to any breast cup, not limited to the exemplary breast cup described herein. In some embodiments, the negative pressure source is a vacuum pump.
In some embodiments, the portable breast pump system 1 includes a positive pressure source that provides positive pressure to the breast cup 2, e.g., to aid in transportation of milk in the portable breast pump system, e.g., to expand and/or compress a pressure chamber 20 and/or a milk chamber 21 if present. In some embodiments, the positive pressure source is a pressure pump, a manually compressible chamber, a vacuum pump, a peristaltic pump, or a valve to the ambient atmosphere.
In some embodiments, pressure applied to the breast cup 2 varies. In some embodiments, the pressure source 9 applies pressure to the breast cup 2 for 1 to 20 cycles (e.g., 1 to 2 cycles, 1 to 3 cycles, 1 to 4 cycles, 1 to 5 cycles, 1 to 6 cycles, 1 to 7 cycles, 1 to 8 cycles, 1 to 9 cycles, 1 to 10 cycles, 1 to 15 cycles, 2 to 3 cycles, 2 to 4 cycles, 2 to 5 cycles, 3 to 7 cycles, 4 to 6 cycles, 5 to 10 cycles, 5 to 15 cycles, 10 to 15 cycles, 15 to 20 cycles, 1 cycle, 2 cycles, 3 cycles, 4 cycles, 5 cycles, 6 cycles, 7 cycles, 8 cycles, 9 cycles, 10 cycles, 11 cycles, 12 cycles, 13 cycles, 14 cycles, 15 cycles, 16 cycles, 17 cycles, 18 cycles, 19 cycles, or 20 cycles). A first cycle may apply a maximum negative pressure of 0 mmHg to about 400 mmHg and/or a maximum positive pressure of about 0 mmHg to about 400 mmHg of positive pressure. A second cycle may apply a maximum negative pressure of about 0 mmHg to about 400 mmHg and/or a maximum positive pressure of about 0 mmHg to about 400 mmHg of positive pressure. Likewise, a third, fourth, fifth, etc., cycle, may apply a maximum negative pressure of about 0 mmHg to about 400 mmHg and/or a maximum positive pressure of about 0 mmHg to about 400 mmHg of positive pressure.
The negative pressure source may provide a negative pressure from about 0 mmHg to about 400 mmHg (e.g., about 0 mmHg to about 10 mmHg, about 0 mmHg to about 20 mmHg, about 0 mmHg to about 30 mmHg,

In some embodiments, pressure applied to the breast cup 2 changes gradually. In some embodiments, pressure applied to the breast cup 2 changes at different rates, e.g., in a first cycle the pressure applied to the breast cup 2 changes over about 0.1 seconds to about 120 seconds (e.g., about 1 second), and in a second cycle the pressure applied to the breast cup 2 changes over about 0.1 seconds to about 120 seconds (e.g., about 5 seconds).
Pressure within the breast cup 2 can provide a pulsating or massaging sensation. In some embodiments, the speed and pressure of the pulsation or massage may be selected by the user. In some embodiments, alternating pressure mimics the action of suckling.
Reservoir
The portable breast pump system 1 may include a reservoir 3, e.g., as shown in FIG. 2. The reservoir 3 is a collection container for the milk, such as a bottle or bag. The reservoir 3 may be polymeric or fabric. The reservoir 3 may be in fluidic communication with the negative pressure source, such that fluid is moved from the breast, through the negative pressure source, to the reservoir 3. Alternatively, when a pressure chamber 20 is present, milk may move to the reservoir 3 without the reservoir 3 being in fluidic communication with the negative pressure source. The reservoir 3 may be releasably connected to a fluid conduit 5, such as a tube. The reservoir 3 may be configured for ease of cleaning. The reservoir 3 may be placed in a dishwasher, refrigerator 28, and/or freezer 30. In some embodiments, the reservoir 3 includes a temperature control element 7 (e.g., a cooling element and/or insulation). In some embodiments, the reservoir 3 includes a refrigerant, e.g., a thermoelectric cooler or an ice or cold pack. The reservoir enclosure 4 may also include a thermostat to regulate the temperature. In some embodiments, the reservoir 3 is insulated, e.g., with foam or a reflective material. Typically, reservoirs 3 are removable from the system, e.g., to feed an infant. In some embodiments, the reservoir 3 may be releasably attached to the pump unit 6. In some embodiments, the reservoir 3 is disposed in a reservoir enclosure 4 within the pump unit 6, wherein the enclosure is physically and/or thermally separate from other components of the pump unit 6, e.g., the pressure source 9. In some embodiments, the reservoir 3 is configured to be connected to the pump unit 6 in the absence of a reservoir enclosure 4, e.g., held by a strap or pocket on the exterior of the pump unit 6. In some embodiments, the reservoir 3 may be releasably connected to the breast cup 2 and/or one or more fluidic conduits. In some embodiments, the reservoir 3 may be disposed separately from the pump unit 6.
In some embodiments, the reservoir 3 includes a volume from about 50 mL to about 1500 mL (e.g., about 50 mL to about 100 mL, about 50 mL to about 150 mL, about 50 mL to about 200 mL, about 50 mL to about 250 mL, about 50 mL to about 300 mL, about 50 mL to about

In some embodiments, the portable breast pump system 1 includes a plurality of reservoirs 3. In some embodiments, portable breast pump system 1 includes from 1 to 10 reservoirs 3 (e.g., from 1 to 2, from 1 to 3, from 1 to 4, from 1 to 5, from 1 to 6, from 1 to 7, from 1 to 8, from 1 to 9, from 2 to 3, from 2 to 4, from 2 to 5, from 2 to 6, from 2 to 7, from 2 to 8, from 3 to 4, from 3 to 5, from 3 to 6, from 4 to 5, from 4 to 6, from 4 to 8, from 4 to 10, from 5 to 8, from 5 to 10, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10). In some embodiments, one reservoir 3 may be disposed in the pump unit 6, and an additional plurality of reservoirs 3 may be disposed in a secondary reservoir enclosure 4. In this embodiment, the secondary reservoir enclosure 4 may be an unattached auxiliary unit.
In some embodiments, each reservoir 3 includes a lid, e.g., wherein lid includes the pressure outlet, the inlet of the reservoir 3, and/or a valve of the reservoir 3. The lid can be integral to or attached to the reservoir 3. In some embodiments, the lid is releasably attached to the reservoir 3. In some embodiments, the lid is screwed or snapped onto the reservoir 3. In particular, the reservoir 3 may include external threads, the lid may include internal threads, and the internal threads and the external threads may provide releasable attachment of the reservoir 3 and lid. In some embodiments, the lid is attached with a magnet, e.g., an electromagnet. In some embodiments, the lid is configured to be opened and/or closed with the electromagnet. In some embodiment, the lid is configured to be opened and/or closed with pressure, e.g., air pressure.
The lid of the reservoir 3 can have a substantially flat or rounded top surface.
In some embodiments, the reservoir 3, e.g., the lid of the reservoir 3, includes a pressure outlet. The pressure outlet may or may not include a valve 24. In some embodiments, the pressure outlet is a breather tube. In some embodiments, the pressure outlet is an orifice 25, e.g., the reservoir 3 or the lid of the reservoir 3 may include an orifice 25. A pressure outlet is advantageous in allowing excess pressure to vent as the reservoir 3 is being filled with milk. In some embodiments, the pressure outlet is solely open as the reservoir 3 is being filled, and the pressure outlet is otherwise nominally closed. An outlet may be connected to a negative pressure source and a vent, e.g., to remove warm air to aid in cooling or to provide suction for milk flow.
Reservoir Disposition
The portable breast pump system 1 may include a reservoir enclosure 4. The reservoir 3 may be within a reservoir enclosure 4, e.g., as shown in FIG. 2. In some embodiments, a plurality of reservoirs 3 is disposed in an enclosure 4. The enclosure 4 may be integral with or detachable from the rest of the pump unit 6. A reservoir 3 may be placed in the enclosure 4 prior to a breast pumping session and removed after a session. In some embodiments, the portable breast pump system 1 includes only a single reservoir.
In some embodiments, the portable breast pump system 1 may include a plurality of reservoir enclosures 4. In some embodiments, the portable breast pump system 1 may include a first reservoir enclosure 4, and a second reservoir enclosure 4. In some embodiments, a first reservoir enclosure 4 may be disposed within the pump unit 6, such that a reservoir 3 may be releasably secured within the pump unit 6. In another embodiment, a second reservoir enclosure 4 may be an auxiliary unit, separate from the pump unit 6, e.g., a cooler, wherein a plurality of reservoirs 3 may be disposed within the second reservoir enclosure 4.
The enclosure 4 is advantageous in that milk may be stored for a prolonged period of time, e.g., at least 10 minutes, at least 15 minutes, at least 20 minutes, at least 30 minutes, at least 40 minutes, at least 45 minutes, at least 60 minutes, at least 1.5 hours, at least 2 hours, at least 3 hours, at least 4 hours, at least 5 hours, at least 6 hours, at least 7 hours, at least 8 hours, at least 9 hours, or at least 10 hours.

The ice pack may be stored in a freezer 30 and then placed in the enclosure before the initiation of breast pumping.
In some embodiments, the cooling element substantially surrounds the reservoir 3. In some embodiments, the cooling element, e.g., the ice pack, is in contact with at least about 5% of the reservoir 3 (e.g., about 10%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 60%, about 70%, about 75%, about 80%, about 90%, or about 95%). In some embodiments, the cooling element conforms to the reservoir 3. In some embodiments, the cooling element is deformable ice pack.
In some embodiments, the enclosure 4 includes an internal recess, in which the reservoir
3 is configured to be placed. In some embodiments, following placement in the recess, the outer surface of the reservoir 3 is in contact with an internal surface of the recess.

In some embodiments, the enclosure 4 is electrically connected to a power source 12. In some embodiments, the power source 12 is a rechargeable or single use battery. In some embodiments, the power source 12 is an AC power source. In some embodiments, the enclosure 4 includes a refrigerant, e.g., a thermoelectric cooler. The reservoir enclosure 4 may also include a thermostat to regulate the temperature.
In some embodiments, the enclosure includes a load cell or weight sensor, e.g., a scale. In some embodiments, the weight sensor may be disposed underneath the reservoir 3, such that the weight of the reservoir 3 is measured. In some embodiments, the weight of the reservoir 3 is measured over time using the weight sensor or load cell. In some embodiments, the weight of the reservoir 3 over time may be used to calculate flow rate of milk during a pumping session. In some embodiments, the weight of the reservoir 3 may be used to determine the volume of milk in the reservoir 3, the identity of reservoirs 3 filled or empty, or when a pumping cycle is complete.
The reservoir may also be attached to the exterior of the pump unit 6, e.g., held in an exterior pocket or by a strap, or disposed separately from the pump unit 6.
The reservoir 3 or enclosure 4 may be wearable, such as including at least one fastener, e.g., a clip and/or strap, to secure the reservoir 3 or enclosure 4 to the user, e.g., the waist of a user. While the present system is advantageous in that it may be used to breast pump while resting or sleeping, the system may also be used while going about daily activities, such as working, caring for an infant, etc.

The portable breast pump system 1 may be configured such that the user may remove the pump unit 6 from a breast cup 2 without removing the breast cup 2. Currently available portable breast pump systems 1 are not designed to allow for removal of the reservoir 3 while leaving a breast cup 2 in place.
The fluid conduit 5 may be selected to have a desired durometer to provide the preferred amount of flexibility for allowance of movement. For example, the fluid conduit 5 may have a durometer from about 25 Shore A scale and about 100 Shore D scale, including 25 A, 30 A, 35 A, 40A, 45A, 50A, 55A, 60A, 65A, 70A, 75A, 80A, 85A, 90A, 95 A, 100A, 10D, 25D, 30D, 35D, 40D, 45D, 50D, 55D, 60D, 65D, 70D, 75D, 80D, 85D, 90D, 95D, 100D, or any durometer therebetween.
The fluid conduit 5 may be configured for ease of cleaning. For example, the portable breast pump system 1 may be run through with water to clean the fluid conduit 5.
In some embodiments, the fluid conduit 5 may be disposed in the center of the breast cup 2, e.g., in line with a nipple. In some embodiments, the fluid conduit 5 may be disposed at the base of breast cup 2, such that milk is expressed to the side. In some embodiments, the fluid conduit 5 may be disposed at the side of the breast cup 2.
The portable breast pump system 1 may include any number of fluid conduits 5, e.g., one, two, three, four, five, six, seven, eight, nine, ten, etc. A portion of fluid conduits 5 may provide air flow to the portable breast pump system 1, while other fluid conduits 5 transport milk.
In some embodiments, the portable breast pump system 1 includes a first fluid conduit 5 providing fluidic communication between the milk chamber 21 and the reservoir 3. In some embodiments, the portable breast pump system 1 includes a second fluid 5 conduit providing fluidic communication between the pressure source 9 and the breast cup 2. In particular, in some embodiments, a second fluid conduit 5 provides fluidic communication between (a) the pressure source 9 (e.g., the negative pressure source and/or the positive pressure source) and (b) the pressure chamber 20.
In some embodiments, the portable breast pump system 1 includes a first fluid conduit 5 providing fluidic communication between the breast cup 2, the negative pressure source, and/or the positive pressure source. In some embodiments, the first fluid conduit 5 is releasably connected to the breast cup 2 and/or pressure source 9. The portable breast pump system 1 may include a second fluid conduit 5 providing fluidic communication between the pressure source 9 and the reservoir 3.

In some embodiments, the third fluid conduit 5 is releasably connected to the control valve 10 and/or first fluid conduit 5.
Additional fluid conduits 5 may transport milk from a second breast. In some embodiments, a first breast cup 2 is connected to a first fluid conduit 5, and a second breast cup 2 is connected to a second fluid conduit 5. In some embodiments, the first fluid conduit 5 and the second fluid conduit 5 merge into a third fluid conduit 5. Similarly, additional fluid conduits 5 may connect a second breast cup 2 to the pressure source 9. These fluid conduits 5 may also merge into a single conduit that connects to the pressure source 9.
In some embodiments, additional fluid conduits 5 may transport milk to additional reservoirs 3. In some embodiments, the milk from different breast pumping sessions is transported to the first reservoir 3 and/or second reservoir 3 through a fluid conduit 5. The milk transported to the first reservoir 3 and/or second reservoir 3 may be transported with the same or different fluid conduit 5, e.g., a first fluid conduit 5 and a second fluid conduit 5. To facilitate better movement, the breast cup 2 and fluid conduits 5 may move with the user. Independent movement of the breast cup 2 and fluid conduits 5 allow the user to have a better range of motion, and further when the user moves the breast cup 2 does not experience force that might remove it from the breast during pumping. In some embodiments, the breast cup 2 includes a movement element. The movement element may be positioned around the outer edge of the breast cup 2. The movement element may be positioned at the nipple tunnel 13 of the breast cup 2. In some embodiments, the first fluid conduit 5 is movably connected to the breast cup 2. In some embodiments, the first fluid conduit 5 is rotatable with respect to breast cup 2. In some embodiments, the first fluid conduit 5 is movably connected to the milk chamber 21. The movement element may be a swivel fitting or a rotating fitting. In some embodiments, the movement element includes a ball bearing.
The movement element may allow the fluid conduit 5 to rotate around the breast cup 2 from about 0° to about 360°, e.g., from about 0° to about 30°, from about 0° to about 60°, about 0° to about 90°, about 0° to about 120°, about 0° to about 150°, about 0° to about 180°, about 0° to about 210°, about 0° to about 240°, about 0° to about 300°, about 30° to about 120°, about 30° to about 180°, about 30° to about 240°, about 30° to about 360°, about 60° to about 120°, about 60° to about 180°, about 60° to about 240°, about 60° to about 360°, about 90° to about 180°, about 90° to about 360°, about 120° to about 240°, about 120° to about 360°, about 150° to about 240°, about 150° to about 360°, about 180° to about 240°, about 180° to about 360°, about 210° to about 360°, about 240° to about 360°, about 270° to about 360°, or about 300° to about 360°.
The movement element may allow the fluid conduit 5 to pivot from the center of the breast cup 2 from about 0° to about 90°, e.g., from about 0° to about 5°, about 0° to about 10°, about 0° to about 15°, about 0° to about 20°, about 0° to about 25°, about 0° to about 30°, about 0° to about 45°, about 0° to about 60°, about 0° to about 75°, about 5° to about 10°, about 5° to about 15°, about 5° to about 20°, about 5° to about 25°, about 5° to about 30°, about 5° to about 45°, about 5° to about 60°, about 5° to about 90°, about 10° to about 15°, about 10° to about 30°, about 10° to about 45°, about 10° to about 60°, about 10° to about 90°, about 30° to about 45°, about 30° to about 60°, about 30° to about 90°, about 45° to about 60°, about 45° to about 90°, or about 60° to about 90°.
A fluid conduit may have any appropriate connector at each end for connection to the breast cup 2, pump, or reservoir 3. Examples of connectors include Luer connectors, threaded connectors, and slip fit connectors. Valves
The portable breast pump system 1 may include one or more valves. In some embodiments, the valve is a control valve, an open-close valve, a one directional valve, a relief valve, a quick-release valve, an inflation valve, or a slow-leak valve. In some embodiments, the valve is a mechanical valve, an inflation valve, an umbrella valve, a butterfly valve, a disk valve, a non-drip valve, a duckbill valve, a ball valve, a batch dispensing valve, a diaphragm valve, a gate valve, a diverting valve, a pinch valve, a piston valve, a plug valve, a saddle valve, a solenoid valve, a stem valve, a stop cock valve, or a three-way valve.
The portable breast pump system 1 may include a control valve 10. The control valve 10 may be in fluidic communication with the breast cup 2 and the pressure source 9. In some embodiments, the fluid conduit 5 providing fluidic communication between the breast cup 2 and pressure source 9 includes the control valve 10. The control valve 10 may selectively provide positive pressure and/or negative pressure to the breast cup 2 from the pressure source 9 in order to selectively increase and/or decrease the pressure provided by the pressure source 9 (e.g., to selectively reduce or stop milk flow by depressurizing the nipple).
The positive pressure provided by the control valve 10 may be between 0 mmHg to 400 mmHg, e.g., about 25 mmHg. In some embodiments, the positive pressure is 0 mmHg, e.g., open atmospheric pressure. In some embodiments, the pressure source 9 and control valve 10 are contained within the same feature.
In some embodiments, the portable breast pump system 1 may include an open-close valve. In some embodiments, the control valve 10 includes an open-close valve. The open-close valve may be configured to open and close fluidic communication between a first element and a second element. In some embodiments, the first element can include a reservoir 3, fluid conduit 5, a pressure chamber 20, a milk chamber 21, or the ambient atmosphere. In some embodiments, the second element can include a reservoir 3, fluid conduit 5, a pressure chamber 20, a milk chamber 21, or the ambient atmosphere.
The portable breast pump system 1 may include one or more one directional valves 15 or anti-backflow valves, e.g., a plurality of one directional valves 15.
The one directional valve 15 may be a duckbill valve or other type of one directional valve.
In some embodiment, the one directional valve 15 may be placed in a fluid conduit 5, e.g., to prevent backflow of milk. In some embodiments, the one directional valve 15 is configured to allow fluid flow from the milk chamber 21 to the reservoir 3. In some embodiments, the one directional valve 15 is disposed in the first fluid conduit 5. In some embodiments, the one directional valve 15 is disposed at the outlet 22 of the milk chamber 21, e.g., FIG. 9D. In some embodiments, the one directional valve 15 is disposed in the diaphragm 18. In some embodiments, the one directional valve 15 may prevent air from entering the first fluid conduit 5, thereby maintaining negative pressure to move the milk.
In some embodiments, the one directional valve 15 is configured to allow fluid flow from the control valve 10 to the breast cup 2 or pressure source 9. In other embodiments, the one directional valve 15 may allow air to flow to the first fluid conduit from the control valve 10, such that the negative pressure and/or positive pressure from the pressure source 9 fluctuate to express milk from the breast. Thus, in some embodiments, the one directional valve 15 follows the control valve 10 in a fluid conduit 5, e.g., in the third fluid conduit 5. In some embodiments, the one directional valve 15 is between the breast cup 2 and the reservoir 3, such that milk cannot backflow from the reservoir 3.
In some embodiments, the inlet to the milk chamber 21 includes a one directional valve, e.g., as shown in FIG. 5. In some embodiments, the one directional valve 15 is a duckbill valve. The portable breast pump system 1 may further include at least one relief valve. In some embodiments, at least one fluid conduit 5 includes a relief valve. In some embodiments, the breast cup 2 includes a relief valve. If vacuum at the breast becomes too strong the relief valve may provide a release of negative pressure to prevent discomfort by the user. A relief valve may be placed such that if a predetermined maximum vacuum level is exceeded in a fluid conduit 5, such as greater than 250 mmHg vacuum (-250 mmHg pressure), the relief valve is able to provide positive pressure. The relief valve can be in the form of a spring and ball, pin and Ciring, or other equivalent mechanical means of providing pressure relief. In some embodiments, the user may activate the release valve. In some embodiments, a user may twist a relief valve to lower or shut off suction. In some embodiments, the portable breast pump system 1 includes one or more quick-release valves. In some embodiments, the outlet 22 of breast cup 2, e.g., the outlet 22 of the milk chamber 21, includes a quick-release valve such that a fluid conduit 5 may be easily connected to the milk chamber 21.
In some embodiments, the portable breast pump system 1 is configured to permit a slow leak of pressure. The slow leak of pressure may be to the ambient atmosphere. A slow leak aids in slowly venting pressure during breast pumping. In some embodiments, the breast cup 2 includes a slow leak of pressure. In some embodiments, the breast shield 19 includes a slow leak of pressure. In some embodiments, the breast shield 19 includes an imperfect seal configured to provide a slow leak. In some embodiments, the breast shield 19 includes an orifice 25 to provide a slow leak. In some embodiments, the slow leak includes a leak rate that would not decrease the maximum negative pressure of a pressure cycle by more than 10% (e.g., 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1%). In some embodiments, the slow leak provides a positive pressure to the breast cup 2 that is equivalent to the maximum applied negative pressure over a period of time from about 0.5 minutes to about 60 minutes (e.g., about 0.5 minutes to about 1 minute, about 0.5 minutes to about 5 minutes, about 0.5 minutes to about 10 minutes, about 0.5 minutes to about 15 minutes, about 0.5 minutes to about 30 minutes, about 1 minute to about 5 minutes, about 2 minutes to about 8 minutes, about 3 minutes to about 7 minutes, about 5 minutes to about 10 minutes, about 5 minutes to about 15 minutes, about 5 minutes to about 30 minutes, about 10 minutes to about 15 minutes, about 10 minutes to about 20 minutes, about 15 minutes to about 30 minutes, about 15 minutes to about 45 minutes, about 30 minutes to about 45 minutes, about 30 minutes to about 60 minutes or about 45 minutes to about 60 minutes). A slow leak valve may be configured to provide the slow leak of pressure. For example, if a maximum pressure of 100 mmHg is applied to the breast cup 2, e.g., the nipple tunnel 13 of the breast shield 19, the slow leak may provide 10 mmHg of positive pressure every minute for 10 minutes.
In some embodiments, the portable breast pump system 1 includes a slow leak valve. The slow leak valve may be configured to provide a slow leak of pressure to the ambient atmosphere. In some embodiments, the slow leak valve includes a leak rate that would not decrease the maximum negative pressure of a pressure cycle by more than 10% (e.g., 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1%) when negative pressure is being applied to the breast cup 2.
In some embodiments, the portable breast pump system 1 may include a flush valve 36 configured to open at a threshold pressure level to allow for high pressure from the pressure source 9 to be utilized to flush the fluid conduit 5 going from the breast cup 2 to the reservoir 3 (e.g., the fluid conduit 5 on the milk or wet side of the portable breast pump system 1). The flush valve 36 may be any suitable type of relief valve or check valve, such as a ball and spring valve or an elastomeric relief valve or check valve. For example, during normal operation, the pressure source 9 may apply a first level of positive pressure (e.g., 50 mmHg or less than 100 mmHg) that is utilized to deform the diaphragm 18 to force milk out of the milk chamber 21 of the breast cup 2 and to the reservoir 3. At the first level of the positive pressure, the flush valve 36 is configured to remain closed, such that the positive pressure is directed into the breast cup 2.
However, the pressure source 9 may apply a second, “flushing” level of positive pressure (e.g., 200 mmHg) to flush any residual milk stuck in the fluid conduit 5 on the milk side or wet side of the portable breast pump system 1. For example, when the second level of positive pressure is applied, the flush valve 36 is configured to open (e.g., due to the pressure rising above the threshold pressure), thereby creating a one-way directional flow path from the pressure source 9 from the fluid conduit 5 on the pressure source side or dry side of the portable breast pump system 1, through the flush valve 36, and into the fluid conduit 5 on the milk or wet side of the portable breast pump system 1 to allow for the positive pressure to flush the milk out of the fluid conduit 5 on the milk or wet side into the reservoir 3. The positive pressure may then escape out of a vent hole on the reservoir 3 (e.g., similar to the pressure outlet 122).
Sensors
The portable breast pump system 1 may also include at least one sensor. At least one sensor may detect a baseline value, e.g., an initial pressure in the breast cup 2. Throughout breast pumping the sensor may continue detecting. Data are compared throughout breast pumping to the initially detected baseline.

In some embodiments, the weight sensor is disposed with a weighing plate 34. Weight sensors may track the weight of the reservoirs 3 over time. In some embodiments, weight data may be used to determine flow rate of milk during a pumping session. In some embodiments, weight sensors may be used to determine the volume of milk inside of a reservoir 3.

Data from the pressure sensor may be used to determine the pressure used to express milk from the nipple. Pressure sensors are also advantageous in that they may detect high pressure levels which may cause discomfort in the user. In some embodiments, the breast cup 2 includes a pressure sensor. In some embodiments, the reservoir 3 includes a pressure sensor. In some embodiments, each reservoir 3 includes a pressure sensor. A pressure sensor in a reservoir 3 can be advantageous in determining over pressurization of the reservoir 3, e.g., as a result of milk being pumped into the reservoir 3.

In various embodiments, the optical sensor includes a singular light source or a plurality of light sources, similarly the photodetector may include a single photodetector or a plurality of photodetectors. In some embodiments, the reservoir 3 may include an optical sensor.
In some embodiments, the optical sensor may sense movement of the breast cup 2 on the breast. Sensing of movement of the breast cup 2 on the breast is advantageous in that it may measure how much the breast cup 2 moves during use, e.g., such as through the night. In some embodiments, the portable breast pump system 1 can alert the user if it becomes unaligned or loose. In some embodiments, the optical sensor is in view of a portion of the skin of the user. In some embodiments, the breast cup 2, e.g., an outer surface of breast cup 2, e.g., the housing, includes the optical sensor. In some embodiments, the optical sensor is mounted on the housing. In some embodiments, the optical sensor may sense the clarity of the milk in the reservoir 3. The clarity of the milk may be indicative of fat content, e.g., a lower clarity may be indicative of a higher fat content.
The portable breast pump system 1 may include at least one viscometer. In some embodiments, the portable breast pump system 1 includes a plurality of viscometers. In some embodiments, the reservoir 3 includes a viscometer. The viscometer may sense the viscosity of the milk, e.g., the milk in the reservoir 3.
In some embodiments, the portable breast pump system 1 includes a Hall effect sensor. A Hall effect sensor is a sensor which detects the presence and magnitude of a magnetic field using the Hall effect. A Hall effect sensor is advantageous in that it may allow the portable breast pump system 1 to collect information on whether the system completes actions. The information collected by the Hall effect sensor may be used to provide assurance and aid in diagnosing any errors.

In some embodiments, the pump unit 6 and/or the breast cup 2 are secured to the same garment.
The garment may be a bra, a bustier, a sports bra, a shirt, a tank top, a bandeau, a strap, a dress, a nightgown, or a nursing bra that provides support to a wearer and/or at least a portion of a portable breast pump system 1. In some embodiments, the garment includes polyester, cotton, linen, satin, organdy, rayon, taffeta, broad cloth, poplin, velour, gauze, canvas, shirting, muslin, tweed, georgette, crepe, wool, twill, gabardine, denim, or drill. In some embodiments, the garment is machine washable.
In some embodiments, the breast cup 2 and/or the pump unit 6 are held in place by compression provided by the garment. The garment may provide a level of compression of the breast cup 2 to the breast such that the subject may move with the breast cup 2 continuing to be secured to the breast. Securement of the breast cup 2 to the breast during movement improves safety and reduces milk leakage. The garment may include a flexible or stretch material, e.g., nylon, elastic, or spandex. The garment may include portions of varying compression, e.g., high compression portions and low compression portions. For example, the material of the garment contacting the breast cup 2 may include a high compression portion. The garment may apply a compression of at least 5 mmHg, e.g., at least 10 mmHg, 15 mmHg, 20 mmHg, 25 mmHg, 30 mmHg, 35 mmHg, 40 mmHg, 45 mmHg, 50 mmHg, 55 mmHg, 60 mmHg, 65 mmHg, 70 mmHg, 75 mmHg, 80 mmHg, 85 mmHg, 90 mmHg, 95 mmHg, 100 mmHg, 125 mmHg, or 150 mmHg. In other embodiments, the garment may apply a compression from about 5 mmHg to about 100 mmHg, e.g., about 5 mmHg to about 10 mmHg, about 5 mmHg to about 15 mmHg, about 10 mmHg, to about 20 mmHg, about 5 mmHg to about 25 mmHg, about 5 mmHg to about 30 mmHg, about 5 mmHg to about 35 mmHg, about 5 mmHg to about 40 mmHg, about 5 mmHg to about 45 mmHg, about 5 mmHg to about 50 mmHg, about 5 mmHg to about 60 mmHg, about 5 mmHg to about 70 mmHg, about 5 mmHg to about 80 mmHg, about 5 mmHg to about 90 mmHg, about 5 mmHg to about 100 mmHg, about 10 mmHg to about 20 mmHg, about 10 mmHg to about 30 mmHg, about 10 mmHg to about 40 mmHg, about 10 mmHg to about 50 mmHg, about 10 mmHg to about 75 mmHg, about 10 mmHg to about 100 mmHg, about 20 mmHg to about 30 mmHg , about 20 mmHg to about 40 mmHg, about 20 mmHg to about 50 mmHg, about 25 mmHg to about 50 mmHg, about 25 mmHg to about 75 mmHg, about 25 mmHg to about 100 mmHg, about 40 mmHg to about 50 mmHg, about 40 mmHg to about 60 mmHg, about 40 mmHg to about 70 mmHg, about 40 mmHg to about 80 mmHg, about 40 mmHg to about 90 mmHg, about 40 mmHg to about 100 mmHg, about 50 mmHg to about 60 mmHg, about 50 mmHg to about 60 mmHg, about 50 mmHg to about 70 mmHg, about 50 mmHg to about 80 mmHg, about 50 mmHg to about 100 mmHg, about 60 mmHg to about 70 mmHg, about 60 mmHg to about 80 mmHg, about 60 mmHg to about 70 mmHg, about 60 mmHg to about 80 mmHg, about 60 mmHg to about 90 mmHg, about 60 mmHg to about 100 mmHg, about 70 mmHg to about 80 mmHg, about 70 mmHg to about 90 mmHg, about 70 mmHg to about 100 mmHg, about 80 mmHg to about 90 mmHg, about 80 mmHg to about 100 mmHg, or about 90 mmHg to about 100 mmHg.
The garment provides access to at least one breast to facilitate breastfeeding and/or pumping. Several embodiments are described to provide access to at least one breast. In some embodiments, the user may pull the garment away from their skin, and insert the breast cup 2 underneath the garment from below or above the garment. In some embodiments, the garment may have openings formed or defined in the material that makes up the garment to provide an opening for access to at least one of the wearer’s breasts. In some embodiments, the opening in the garment has a smaller diameter than the largest diameter of the breast cup 2. In some embodiments, the breast cup 2 is inserted into at least one opening formed in the material of the garment, and compression of the material secures it to the breast. This configuration is advantageous such that the breast cup 2 may not be pulled out of the garment unintentionally. For example, the nipple tunnel 13 of the breast cup 2 may be inserted through the opening in the garment such that the wide portion 8 of the breast cup 2 may contact the garment, but not pass through. The nipple tunnel 13 of the breast cup 2 may then be releasably connected to a fluid conduit 5.
The opening in the garment may have a diameter from about 5 mm to about 250 mm, e.g., from about 5 mm to about 10 mm, about 5 mm to about 20 mm, about 5 mm to about 25 mm, about 5 mm to about 30 mm, about 5 mm to about 40 mm, about 5 mm to about 50 mm, about 5 mm to about 75 mm, about 5 mm to about 100 mm, about 10 mm to about 20 mm, about 10 mm to about 25 mm, about 10 mm to about 30 mm, about 10 mm to about 40 mm, about 10 mm to about 50 mm, about 20 mm to about 25 mm, about 20 mm to about 30 mm, about 20 mm to about 40 mm, about 20 mm to about 50 mm, about 25 mm to about 50 mm, about 25 mm to about 75 mm, about 30 mm to about 40 mm, about 30 mm to about 50 mm, about 40 mm to about 50 mm, about 50 mm to about 75 mm, about 50 mm to about 100 mm, about 50 mm to about 125 mm, about 50 mm to about 150 mm, about 50 mm to about 75 mm, about 75 mm to about 100 mm, about 75 mm to about 125 mm, about 75 mm to about 150 mm, about 75 mm to about 175 mm, about 75 mm to about 200 mm, about 100 mm to about 125 mm, about 100 mm to about 150 mm, about 100 mm to about 175 mm, about 100 mm to about 200 mm, about 125 mm to about 150 mm, about 125 mm to about 175 mm, about 125 mm to about 200 mm, about 150 mm to about 175 mm, about 150 mm to about 200 mm, about 150 mm to about 250 mm, or about 200 mm to about 250 mm. The opening may have a diameter less than 100 mm, e.g., less than 90 mm, 80 mm, 70 mm, 60 mm, 50 mm, 40 mm, 30 mm, 25 mm, 20 mm, 10 mm, or 5 mm.
The garment may include at least one layer, e.g., two layers. The two layers may overlap such that they may be pulled apart to reveal at least one breast. In some embodiments, the garment includes at least two layers, and the breast cup 2 is secured to the breast by positioning between at least two layers. Alternatively, or additionally, the garment may include snaps, buttons, or a zipper that may be opened to provide access to at least one breast. In addition to providing access to at least one breast, the portable breast pump system 1 may include a fastener for securing the breast cup 2 to the garment. The portable breast pump system 1 may also include a fastener for securing the fluid conduit 5. The fastener may be used to route the fluid conduit 5 to an advantageous location (e.g., under the arm, or under the garment), such that the fluid conduit 5 does not impede the user’s freedom of motion. The portable breast pump system 1 may also include a fastener system for pump unit 6, and/or the reservoir 3, and/or reservoir enclosure 4. The fastener may attach the pump unit 6, and/or the reservoir 3, and/or reservoir enclosure 4 to the user, such that they are able to conduct their daily activities while breast pumping. The fastener may include a clip, a strap, a hook, a zipper, a magnet, a pin, a button, a snap, a hook and loop fastener (e.g., VELCRO®), or a combination thereof. The fastener may fasten the pump unit 6, and/or the reservoir 3, and/or reservoir enclosure 4 to the user in such a way that they may have freedom of motion, e.g., fasten the reservoir 3 and/or reservoir enclosure 4 to the waist of the user.
Securement to the breast may be further improved by negative pressure provided by the pressure source 9.
The portable breast pump system 1 may be reversibly connected to the garment before or after the garment is donned. In some embodiments, the pump unit 6, the breast cup 2, and/or housing are reversibly secured to the garment and then the garment is donned. In some embodiments, the garment is donned, and then the pump unit 6, the breast cup 2, and/or housing are reversibly secured to the garment. In some embodiments, the pump unit 6, the breast cup 2, and/or housing are irreversibly secured to the garment. In some embodiments, the fluid conduit 5 is reversibly secured to the breast cup 2 and/or the pump unit 6 after the garment is donned. In some embodiments, the fluid conduit 5 is reversibly secured to the breast cup 2 and/or the pump unit 6 prior to the garment being donned.
In some embodiments, the outer surface of breast cup 2 has a lower coefficient of friction than the inner surface of the garment to allow freedom of movement. Without wishing to be bound to theory, if there is a lower coefficient of friction between the breast cup 2 and the garment than between the breast cup 2 and the breast, then relative movement of the garment is less likely to move the breast cup 2 out of position. In some embodiments, the coefficient of friction between the outer surface of the breast cup 2, e.g., the housing, and the garment is less than 0.4 (e.g., 0.35, 0.3, 0.25, 0.2, 0.15, 0.1, or 0.05). In some embodiments, the outer surface of the breast cup 2, e.g., the housing, can include a smooth material. In some embodiments, the outer surface of the breast cup 2, e.g., the housing, can include smooth plastic or fabric. In some embodiments, the outer surface of the breast cup 2, e.g., the shield 19, can include PET, PP, PTFE, polyethylene, HDPE, LDPE, PC, nylon, acetal, PEEK, PPS, or polyester. In some embodiments, the outer surface of the breast cup 2, e.g., the housing, can include cotton, linen, satin, organdy, rayon, taffeta, broad cloth, poplin, velour, gauze, canvas, shirting, muslin, tweed, georgette, crepe, wool, twill, gabardine, denim or drill.
Portable Breast Pump System Control
The portable breast pump system 1 may include controls that are operable by a user to select or modify at least one of: pumping program or mode, frequency of pumping cycle, maximum suction pressure achieved during a pumping cycle, latch suction pressure achieved during the pumping cycle, volume of the pressure chamber 20, pumping force, and pumping session time. The controls may be present on the surface of the pump unit 6, e.g., on the display. Alternatively, or in addition, the controls may be present in an application on an external computer, e.g., a mobile device. Alternatively, the pump unit 6 does not include controls, and the portable breast pump system 1 is solely controlled through an application on an external computer, e.g., a mobile device. Control of the portable breast pump system 1 through an application on an external computer is advantageous in that a user may control the device in any position. In some embodiments, the portable breast pump system 1 can have a wait time set, e.g., through the display or an application on an external computer, such that the user has time to contact the breast cup 2 to their breast before the portable breast pump system 1 begins pumping.
Control of the portable breast pump system 1 may be customized. The customized pump functions include modifications to at least one of: maximum suction pressure level, latch suction pressure level, suction pressure waveform over a pumping cycle, phases of extraction or feeding times, rest times, heating temperatures and times, vibration frequency and duration, pumping session time, and distribution of milk to reservoirs 3. The user may input at least one pump program into the portable breast pump system 1, e.g., through the display or application on an external computer. For example, the user may set the number of minutes that the portable breast pump system 1 will run before shutting off automatically and/or the user may set a time for the portable breast pump system 1 to engage pumping. Custom pump programming is advantageous in that the user may control how long they pump for so that they may go about their daily activities, without the worry that the pump will continue endlessly. In some embodiments, the pumping frequency may be programmed to slow down gradually during operation, e.g., towards the end of a preprogrammed pumping time.
Wireless Control
The control unit may be configured to send signals to and receive signals from an external computer, e.g., a mobile device.
The control unit may include a transmission element, e.g., a wireless transmission element, and a receiver element for wirelessly sending signal to and receiving signals from the external computer. In some embodiments, the transmission element is a BLUETOOTH® transmission element. In some embodiments, the transmission element is a BLUETOOTH® low energy (BLE) transmission element.
The external computer may include a processor and instructions, which when executed, cause the processor to customize pump functions and send customized pump functions to the control unit. In some embodiments, the custom pump functions are based on the signals received from the control unit, such as measurements taken by sensors. In some embodiments, the user is able to program different custom pump programs, e.g., a daytime program and a nighttime program. For example, the user can program or select from a daytime program, a workday program, an early evening program, a sleep program, etc.
The external computer may include a processor and instructions, which when executed, cause the processor to calculate the volume of milk extracted and track expression efficiency and monitor it over time. In some embodiments, the calculation of milk extracted, and expression efficiency are based on signals received from the control unit, such as measurements taken by the sensors.
The external computer may include a processor and instructions, which when executed, cause the processor to transport milk from a breast pumping session to a reservoir 3, including transporting milk from a first breast pumping session to a first reservoir 3, and milk from a second breast pumping session to a second reservoir 3.
The external computer may include a processor and instructions, which when executed, cause the processor to track inventory of previous pumping sessions, including tracking at least one of the dates of the previous pumping sessions, volumes pumped in the previous pumping sessions, and specific tracking numbers for specific milk collection containers into which milk has been pumped in the previous pumping sessions.
The external computer may include a processor and instructions, which when executed, cause the processor to one or more of monitor remaining battery power of the battery or output a warning when the battery reaches a predetermined low level of charge.
The external computer may include a processor and instructions, which when executed, cause the processor to display on the application screen or on the display of the portable breast pump system 1 the time left in the pumping session, measurements taken by the at least one sensor, and/or one or more photos of the user’s choosing on the display.
Breast cup
The portable breast pump system 1 may be employed with any suitable breast cup that can be in fluidic communication with the system, e.g., via a fluidic conduit. As is known in the art, breast cups may include a breast shield 19 component that is designed to contact the breast and surround the nipple. Breast cups 2 may also include a housing to surround the breast shield 19. The breast cup 2 may be actuated manually or by automation, e.g., by pressure cycles from a pump or other pressure source. The system is advantageous for automated pumping as it allows for the breast cup 2 to stay in place. Pumping milk into a reservoir 3 may occur by the action of a diaphragm 18, when present. Other pumping mechanisms may also be employed, including providing positive pressure to the breast cup, e.g., by forced air or providing negative pressure to a fluid conduit 5 between the breast cup 2 and a reservoir 3. Negative pressure may be employed by a peristaltic pump or by air being pulled into the fluid conduit 5. These may also act to flush the conduit after a pumping session or after a set number of pumping sessions. For example, a flush line may connect to the fluid conduit 5, with both the flush line and the fluid conduit 5 having one directional valve 15 to prevent backflow. Negative pressure may be applied by reducing pressure in a reservoir 3, and a vent may be present to release pressure when desired.
In some aspects, the portable breast pump system 1 may be used with any embodiment of the breast cups described in this disclosure. An exemplary breast cup 2 is shown in FIG. 1. The breast cup 2 may include a housing (e.g., including an upper housing 17 and a lower housing or milk chamber wall 26), a breast shield 19, and a diaphragm 18 disposed between the upper housing 17 and the breast shield 19 (and also between the upper housing 17 and the lower housing or milk chamber wall 26), such that the diaphragm 18 separates a pressure chamber 20 from a milk chamber 21. In some embodiments, the breast cup 2 includes the lower housing or milk chamber wall 26, e.g., as shown in FIG. 7. The milk chamber wall 26 can be disposed between the diaphragm 18 and the breast shield 19, thereby defining the milk chamber 21 between the diaphragm 18 and the milk chamber wall 26. Pressurization and/or depressurization of the pressure chamber 20 deforms the diaphragm 18, and thereby expands or compresses the milk chamber 21. The pressure chamber 20 is not fluidically connected to the milk chamber or breast shield. In some embodiments, the pressure chamber 20 is not in fluidic communication with the milk chamber or breast shield.
One or more of the components of the breast cup 2, including the housing, the diaphragm 18, the breast shield 19, and/or the milk chamber wall 26 may be removably attached to the breast cup 2. In some embodiments, the pressure chamber 20 and/or the milk chamber 21 are distinct reservoirs, as opposed to chambers formed from the space between other components (e.g., the housing, the diaphragm 18, the milk chamber wall 26, and/or the breast shield 19, and may be reversibly attached to the breast cup 2). For example, the milk chamber 21 may be removed from the breast cup 2 to be cleaned or replaced.
In some embodiments, at least one of the housing, the diaphragm 18, the breast shield 19, and/or the milk chamber wall 26 can include a protrusion and/or a recess, such as a groove. In some embodiments, a protrusion on at least one of the housing, the diaphragm 18, the breast shield 19, and/or the milk chamber wall 26 is configured to mate with a recess, such as a groove, on at least one of the housing, the diaphragm 18, the breast shield 19, and/or the milk chamber wall 26. Mating between a protrusion and a recess, e.g., a groove, allows two components to be snapped, slid, or friction-fit together. FIG. 7 shows an embodiment of the breast cup 2, in which the housing, the diaphragm 18, the breast shield 19, and/or the milk chamber wall 26 are attached together at least partially using protrusions and recesses, e.g., grooves.
Alternatively, or in addition, at least one of the housing, the diaphragm 18, the breast shield 19, and/or the milk chamber wall 26 can be attached together using any other suitable connector, e.g., an adhesive (e.g., glue) or a fastener (e.g., a screw). FIGS. 9A-9D show an embodiment of the breast cup 2, in which the housing, the diaphragm 18, the breast shield 19, and/or the milk chamber wall 26 are attached together at least partially using a fastener.
The breast cup 2, e.g., via the breast shield 19, contacts the breast of the user and can provide a seal during breast pumping, such that milk does not leak. The breast cup 2, the breast shield 19, and/or the housing are configured to conform to the breast comfortably for frequent and/or long periods of wear, such that the breast is not irritated. For example, the interior of the breast cup 2, e.g., the breast shield 19, may conform to the breast and/or the nipple of the user.
The breast cup 2, the breast shield 19, and/or the housing may be in a shape for improved conformance to the breast, e.g., a funnel, a cone, or a dome. The exterior of the breast cup 2 may be rounded. A rounded breast cup 2 may appear breast-like, e.g., to be worn discreetly under clothing. The breast cup 2, the breast shield 19, and/or the housing may be toroidal, e.g., forming a ring, with the breast cup 2, the breast shield 19, and/or the housing covering the breast.
In some embodiments, the breast cup 2 is funneled. The breast cup 2 may include a wide portion 8 and a nipple tunnel 13, e.g., as shown in FIG. 1, in which the wide portion 8, e.g., of the breast cup 2, initially contacts the breast, and the nipple tunnel 13, e.g., of the breast cup 2, is configured to receive the nipple.
The wide portion 8 of the breast cup 2 may have a largest diameter from about 50 mm to about 250 mm (e.g., about 50 mm to about 75 mm, about 50 mm to about 100 mm, about 50 mm to about 125 mm, about 50 mm to about 150 mm, about 50 mm to about 75 mm, about 75 mm to about 100 mm, about 75 mm to about 125 mm, about 75 mm to about 150 mm, about 75 mm to about 175 mm, about 75 mm to about 200 mm, about 100 mm to about 125 mm, about 100 mm to about 150 mm, about 100 mm to about 175 mm, about 100 mm to about 200 mm, about 125 mm to about 150 mm, about 125 mm to about 175 mm, about 125 mm to about 200 mm, about 150 mm to about 175 mm, about 150 mm to about 200 mm, about 150 mm to about 250 mm, or about 200 mm to about 250 mm). The nipple tunnel 13 of the breast cup 2 may have a largest diameter greater than 25 mm (e.g., greater than 50 mm, 75 mm, 100 mm, 125 mm, 150 mm, 175 mm, 200 mm, 225 mm, or 250 mm).
The breast cup 2, the breast shield 19, and/or the housing may include a gel such that it allows better conformance to the breast. In some embodiments, the breast cup 2 conforms to the breast and supports the weight of the breast cup 2 and fluid conduits 5 extending from the breast cup 2 without additional adhesives, gels, straps, or bras. In some embodiments, the breast cup 2 secures to a garment, such as a bra or shirt.
The breast cup 2, the breast shield 19, and/or the housing may include a food contact substance. Additionally, or alternatively, the breast cup 2, the breast shield 19, and/or the housing may include an infant grade material. The breast cup 2, the breast shield 19, and/or the housing may include a flexible material, e.g., formed from a polymeric material such as silicone. The breast cup 2, the breast shield 19, and/or the housing may include a rigid material. The breast cup 2, the breast shield 19, and/or the housing may include PET, PVC, PTFE, polyethylene, HDPE, LDPE, copolyester (e.g., Tritan EX401), PP, polystyrene, a thermoplastic elastomer, thermoplastic polyurethane, PC, nylon, PVDF, or silicone. In some embodiments, breast cup 2, the breast shield 19, and/or the housing can include a fabric (e.g., polyester, cotton, linen, satin, organdy, rayon, taffeta, broad cloth, poplin, velour, gauze, canvas, shirting, muslin, tweed, georgette, crepe, wool, twill, gabardine, denim, or drill).
In some embodiments, the breast cup 2 may be in fluidic communication with the pressure source 9, such that milk is pumped from the breast to the reservoir 3.
In some embodiments, the breast cup 2 may have a second fluidic conduit providing fluidic communication between the breast cup 2 and the pressure source 9. In some embodiments, the breast cup 2 may have a first fluidic conduit providing fluidic communication between the breast cup 2 and a reservoir 3. In some embodiments, the first fluidic conduit is releasably connected to the breast cup 2 via a first outlet 22 on the breast cup 2, e.g., from the milk chamber. In some embodiments, the second fluidic conduit is releasably connected to the breast cup 2 via an inlet to the breast cup 2, e.g., in the pressure chamber 20. In some embodiments, the first and second fluidic conduits are releasably connected to the breast cup 2 via a connector, e.g., wherein the inlet and outlet 22 to which the first fluidic conduit and the second fluidic conduit connect are not disposed adjacent to each other. In some embodiments, the connector further comprises a half-moon shape.
In some embodiments, the breast cup 2 allows for the extension of the nipple when negative pressure is supplied, e.g., by the pressure source 9, e.g., at a first pressure, in order to express milk. When positive pressure is supplied by a control valve 10 and/or a positive pressure source, e.g., at a second pressure, the nipple contracts, and reduces or stops milk flow until a higher negative pressure is supplied.
In some embodiments, the interior of the breast cup 2, e.g., the interior of the breast shield 19, includes an open area, e.g., the nipple tunnel 13, dimensioned to allow for clearance and space in front of the nipple to permit milk to exit the nipple even when the nipple is pulled forward by suction.
In some embodiments, the portable breast pump system 1 includes two breast cups 2, e.g., one for each breast. In embodiments in which the portable breast pump system 1 includes two breast cups 2, the two breast cups 2 can each include a housing, a breast shield 19, and a diaphragm 18. A user can use both of the breast cups 2 at the same time, or just one of the two at any given time.
One or more components of the breast cup 2 may be clear to allow for visualization of the nipple, e.g., for alignment, during placement. The breast cup 2 may also include an opaque cover or be flat to make the nipple not visible after placement of the breast cup 2. The breast cup 2 may also include a lens to magnify the nipple to aid in alignment.
Breast Shield
The breast cup 2 can include a breast shield 19, e.g., as shown in FIGS. 9A-9D. The breast shield 19 contacts the breast of the user and can provide an airtight seal during breast pumping, such that milk does not leak from the breast cup 2. The breast shield 19 is configured to conform to the breast comfortably for frequent and/or long periods of wear, such that the breast is not irritated. The breast shield 19 can include a wide portion 8 and a nipple tunnel 13, in which the wide portion 8 initially contacts the breast, and the nipple tunnel 13 is configured to receive the nipple. For example, the breast shield 19 can conform to the breast and provide space for the nipple, e.g., in the nipple tunnel.
In some embodiments, the nipple tunnel 13 has a length from about 5 mm to about 75 mm (e.g., about 5 mm to about 10 mm, about 5 mm to about 20 mm, about 5 mm to about 30 mm, about 5 mm to about 40 mm, about 5 mm to about 50 mm, about 10 mm to about 20 mm, about 10 mm to about 30 mm, about 10 mm to about 40 mm, about 10 mm to about 50 mm, about 10 mm to about 60 mm, about 10 mm to about 70 mm, about 25 mm to about 50 mm, about 25 mm to about 75 mm, about 50 mm to about 75 mm, about 5 mm, about 6 mm, about 7 mm, about 8 mm, about 9 mm, about 10 mm, about 11 mm, about 12 mm, about 13 mm, about 14 mm, about 15 mm, about 16 mm, about 17 mm, about 18 mm, about 19 mm, about 20 mm, about 21 mm, about 22 mm, about 23 mm, about 24 mm, about 25 mm, about 26 mm, about 27 mm, about 28 mm, about 29 mm, about 30 mm, 35 mm, about 40 mm, about 45 mm, about 50 mm, about 55 mm, about 60 mm, about 65 mm, about 70 mm, or about 75 mm).
In some embodiments, the nipple tunnel 13 has a minimum diameter from about 10 mm to about 130 mm (e.g., about 10 mm to about 20 mm, about 10 mm to about 30 mm, about 10 mm to about 40 mm, about 10 mm to about 50 mm, about 10 mm to about 60 mm, about 10 mm to about 70 mm, about 10 mm to about 100 mm, about 25 mm to about 50 mm, about 25 mm to about 75 mm, about 30 mm to about 130 mm, about 50 mm to about 75 mm, about 50 mm to about 130 mm, about 70 mm to about 130 mm, about 100 mm to about 130 mm, about 10 mm, about 11 mm, about 12 mm, about 13 mm, about 14 mm, about 15 mm, about 16 mm, about 17 mm, about 18 mm, about 19 mm, about 20 mm, about 21 mm, about 22 mm, about 23 mm, about 24 mm, about 25 mm, about 26 mm, about 27 mm, about 28 mm, about 29 mm, about 30 mm, 35 mm, about 40 mm, about 45 mm, about 50 mm, about 55 mm, about 60 mm, about 65 mm, about 70 mm, about 75 mm, about 80 mm, about 90 mm, about 100 mm, about 110 mm, about 120 mm, about 125 mm, or about 130 mm). In some embodiments, the diameter of the nipple tunnel 13 is between about 20 and about 40 mm.
In some embodiments, the nipple tunnel 13 has a maximum diameter from about 10 mm to about 130 mm (e.g., about 10 mm to about 20 mm, about 10 mm to about 30 mm, about 10 mm to about 40 mm, about 10 mm to about 50 mm, about 10 mm to about 60 mm, about 10 mm to about 70 mm, about 10 mm to about 100 mm, about 25 mm to about 50 mm, about 30 mm to about 130 mm, about 25 mm to about 75 mm, from about 50 mm to about 75 mm, about 50 mm to about 130 mm, about 70 mm to about 130 mm, about 100 mm to about 130 mm, about 10 mm, about 11 mm, about 12 mm, about 13 mm, about 14 mm, about 15 mm, about 16 mm, about 17 mm, about 18 mm, about 19 mm, about 20 mm, about 21 mm, about 22 mm, about 23 mm, about 24 mm, about 25 mm, about 26 mm, about 27 mm, about 28 mm, about 29 mm, about 30 mm, 35 mm, about 40 mm, about 45 mm, about 50 mm, about 55 mm, about 60 mm, about 65 mm, about 70 mm, about 75 mm, about 80 mm, about 90 mm, about 100 mm, about 110 mm, about 120 mm, about 125 mm, or about 130 mm).
In some embodiments, the diameter of the nipple tunnel 13 is between about 11 and 30 mm.
The breast shield 19 can possess a shape for improved conformance to the breast, e.g., a funnel, a cone, or a dome. The breast shield 19 can be rounded or toroidal, e.g., forming a ring.
The breast shield 19 can include an inlet to the milk chamber 21, such that milk may enter the milk chamber 21 once expressed from the nipple. In some embodiments, the diaphragm 18 releasably contacts the inlet, e.g., at a sealing point 23, providing a seal when negative pressure is not applied to the pressure chamber 20. Thus, in some embodiments, the diaphragm 18 releasably seals the inlet. The releasable sealing of the inlet to the milk chamber 21 is shown in FIG. 4. In some embodiments, the inlet includes a valve, e.g., an umbrella valve 24, e.g., as shown in FIG. 5, or a non-drip valve. In some embodiments, the valve is a mechanical valve, an umbrella valve 24, a butterfly valve, a disk valve, or a duckbill valve.
In some embodiments, the inlet includes at least one orifice 25, e.g., as shown in FIG. 6. In some embodiments, the inlet includes a plurality of orifices 25. In some embodiments, the plurality of orifices 25 are circumferentially arranged at the nipple tunnel 13 of the breast shield 19, e.g., as shown in FIG. 6. In some embodiments, the diaphragm 18 releasably contacts at least one of the orifices 25, e.g., at sealing point 23, providing a seal when negative pressure is not applied to the pressure chamber 20. In some embodiments, the diaphragm 18 contacts the plurality of orifices 25. Thus, in some embodiments, the diaphragm 18 releasably seals at least one orifice, e.g., at sealing point 23. In some embodiments, the diaphragm 18 seals the plurality of orifices 25, e.g., at sealing point 23. In some embodiments, the diaphragm 18 releasably contacts the breast cup 2 at a point as to separate the at least one orifice 25 from the milk chamber 21.
In some embodiments, the orifice 25 can have a diameter from about 0.5 mm to about 10 mm (e.g., about 0.5 mm to about 1 mm, about 0.5 mm to about 1.5 mm, about 0.5 mm to about 2 mm, about 0.5 mm to about 5 mm, about 1 mm to about 2 mm, about 1 mm to about 3 mm, about 1 mm to about 4 mm, about 1 mm to about 5 mm, about 1 mm to about 6 mm, about 1 mm to about 7 mm, about 1 mm to about 8 mm, about 1 mm to about 9 mm, about 1 mm to about 10 mm, about 3 mm to about 7 mm, about 5 mm to about 10 mm, about 8 mm to about 10 mm, about 1mm, about 2mm, about 3 mm, about 4 mm, about 5 mm, about 6 mm, about 7 mm, about 8 mm, about 9 mm, or about 10 mm).
In some embodiments, the diaphragm 18 is not configured to contact the inlet, e.g., at sealing point 23. In some embodiments, the breast cup 2, e.g., the breast shield 19 includes a fitting that may seal the inlet from the milk chamber 21. In some embodiments, the fitting is a plug or a cover.
The wide portion 8 of the breast shield 19 can seal to the breast, while the nipple tunnel 13 provides room for the nipple to be expanded to express milk. In some embodiments, the wide portion 8 of the breast shield 19 seals to the breast, e.g., around the base of the nipple. In some embodiments, the breast shield 19 is sealed to the breast before a breast pumping session commences.
In some embodiments, a positive or negative pressure may be applied to the breast cup 2 prior to a breast pumping session to contract the breast shield 19, e.g., the wide portion 8 of the breast shield 19, such that the breast shield 19 may be sealed to the breast. Following a breast pumping session, a positive or negative pressure may be applied to the breast cup 2 such that the breast cup 2, e.g., the wide portion 8 of the breast shield 19, may be unsealed from the breast. In some embodiments, the edge of the wide portion 8 of the breast shield 19 solely contacts the breast before applying negative pressure. Following application of negative pressure to the breast cup 2, substantially all of the wide portion 8 of the breast shield 19 may contact the breast.
Negative pressure can be applied to the breast cup 2 for sealing of the breast cup 2 to the breast from the pressure source 9, or from force applied manually by the user to the breast cup 2, e.g., to the housing. For example, the user may push on the breast cup 2, e.g., the housing, to provide negative pressure to the breast shield 19 and seal the breast cup 2 to the breast. Positive pressure can be applied to the breast cup 2 to unseal the breast cup 2 from the breast from the positive pressure source, from a valve to the ambient atmosphere, from a slow leak, or from force manually applied by the user to the breast cup 2. For example, a user may pull on the breast cup 2, e.g., the housing, to provide positive pressure to the breast shield 19 and unseal the breast cup 2 from the breast. In some embodiments, the breast cup 2 includes an air pocket, to which negative or positive pressure can be applied to seal or unseal the breast cup 2 to the breast.
The inside of the breast shield 19 can include at least one protrusion 27 to improve the sealing of the breast shield 19 to the breast. FIG. 8 A and FIG. 8B show embodiments of the breast shield 19 having protrusions 27. In some embodiments, the protrusion 27 is a toroidal ridge, see, e.g., FIG. 8A. In some embodiments, the protrusion 27 is a curved toroidal ridge, see, e.g., FIG. 8B. In some embodiments, the outer surface of the breast shield 19 includes an indent to form the protrusion 27 on the inner surface of the breast shield 19, see, e.g., FIG. 8 A.
Sealing of the breast shield 19 to the breast may keep milk from leaking around the breast and improve the security of the breast shield 19 to the breast during breast pumping. Unsealing of the breast shield 19 from the breast when a breast pumping session is not ongoing, e.g., to allow air flow, may improve comfort, reduce skin temperature, and reduce sweat buildup. Furthermore, expansion and contraction of breast shield 19 allow the breast shield 19 to fit breasts of a plurality of sizes, e.g., AA cup, A cup, B cup, C cup, D cup, DD cup, DDD cup, E cup, F cup, etc.
The ability to expand and contract the nipple tunnel 13 of the breast shield 19, mechanically or using pressure, may be advantageous in setting up the portable breast pump system 1 for breast pumping. In some embodiments, the internal diameter of the nipple tunnel 13 of breast shield 19 is reduced slowly while moving the breast shield 19 into position, such that the user may be able to center the breast shield 19 on their nipple via touch and feel without the need for a line of sight. In some embodiments, the housing and diaphragm 18 may be or may include a clear material, such that the user may additionally use line of sight to center the breast shield 19 on their nipple.
In some embodiments, the breast shield 19 and/or the housing include ridges, bumps, and/or dimples. In some embodiments, the internal surface of the breast shield 19 and/or the housing include ridges, bumps, or dimples. Ridges, bumps, and/or dimples may aid in aligning the breast cup 2 to the breast, adherence of the breast cup 2 to the skin, reduction of heat buildup, and may provide further comfort when a user is wearing the breast cup. In some embodiments, the ridges, bumps, and/or dimples include foam.
In some embodiments, the ridge includes a straight ridge, a curved ridge, a zig-zag ridge, an undulating ridge, a spiral ridge, a continuous ridge, or a broken ridge. The breast shield 19 can include a plurality of ridges. In some embodiments, the ridges are from about 1 mm to about 100 mm apart (e.g., about 1 mm to about 2 mm, about 1 mm to about 5 mm, about 1 mm to about 10 mm, about 1 mm to about 25 mm, about 1 mm to about 50 mm, about 5 mm to about 10 mm, about 10 mm to about 25 mm, about 10 mm to about 50 mm, about 25 mm to about 75 mm, about 50 mm to about 100 mm, about 1 mm, about 5 mm, about 10 mm, about 15 mm, about 20 mm, about 25 mm, about 30 mm, about 40 mm, about 50 mm, about 60 mm, about 70 mm, about 75 mm, about 80 mm, about 90 mm, or about 100 mm).
Air may flow between the ridges, bumps, and/or dimples where the surface of the breast shield 19 does not contact the breast. In some embodiments, the ridges, bumps, and/or dimples extend from an edge of the breast shield 19 to an inner point of the inner surface of the breast shield 19. In this regard, the ridges, bumps, and/or dimples may form an air passage from the ambient atmosphere to the inner surface of the breast shield 19. Thus, in some embodiments, the breast shield 19 includes a fluid conduit 5, wherein the fluid conduit 5 may be defined by the (i) ridges, bumps, and/or dimples, (ii) the skin of the breast, and (iii) the inner surface of the breast shield 19. The fluid conduit 5 may create a chimney effect resulting in improved air circulation in the breast shield 19.
Alternatively, or additionally, the breast cup 2 may be manually pressed in order to expel air from the breast shield 19. Following the release of the breast cup 2, fresh air may flow back into the breast shield 19. In some embodiments, this method of circulating air in the breast shield 19 may be accomplished before or following a breast pumping session. For example, a spiral ridge on the inner surface of the breast shield 19 may form a fluid conduit 5 with the skin of the breast. When the breast cup 2 is pressed, air inside the breast shield 19 may be transported around the spiral to the ambient atmosphere. When the pressure is removed from the breast cup 2, fresh air may be transported around the spiral back into the breast shield 19. Ridges, bumps, and/or dimples may also reduce the peeling effect when removing the breast cup 2. A reduction in the peeling effect can improve comfort, especially for those users with sensitive skin.
The breast shield 19 may include a material that becomes soft by heating and further conforms to the geometry of the body. The breast shield 19 can include one or more formable chambers, which aid in conforming the breast shield 19 to the breast of the user. In some embodiments, the formable chambers include a fluid, e.g., a gas or liquid. In some embodiments, the breast shield 19 includes flexible, gel-like materials such as cross-linked silicone. In some embodiments, the breast shield 19 includes one or more thixotropic fluids.
In some embodiments, breast shield 19 includes a material that may store heat for improved comfort. In some embodiments, the breast shield 19 includes a material that may expel heat into the ambient environment. In some embodiments, the breast shield 19 includes regions of material that may store heat, and regions of material that may expel heat. In some embodiments, the regions of material that may expel heat include regions with ridges, bumps, and/or dimples.
The breast shield 19 can include a food contact substance. Alternatively, or additionally, the breast shield 19 can include an infant grade material. The breast shield 19 can include polyvinyl chloride (PVC), polyethylene, PP, polystyrene, a thermoplastic elastomer, thermoplastic polyurethane, PC, nylon, polyvinylidene fluoride (PVDF), or silicone. The breast shield 19 can include a flexible material, e.g., formed from a polymeric material such as silicone. The breast shield 19 can include a rigid material. In some embodiments, the breast shield 19 includes a water-resistant or a sweat-resistant material.
In some embodiments, two human breasts are contacted with two breast shields 19 to pump milk from both breasts.
Housing
The breast cup 2 may include a housing, including an upper housing 17 and a lower housing 26. The housing may be disposed on the exterior of breast cup 2, e.g., around the breast cup 2, e.g., be outward facing. The housing may form a portion of the outer surface of the pressure chamber 20 or be a separate component.
In some embodiments, the housing may be disposed around the wide portion 8 of the breast shield 19, e.g., the first point of contact with the breast. The housing may conform to the breast. The housing may include a gel such that it conforms to the breast. In some embodiments, the housing conforms to the breast and supports the weight of the breast cup 2, the housing, and fluid conduits 5 extending from the breast cup 2 without additional adhesives, gels, straps, or bras. In some embodiments, the housing does not conform to the breast. The housing may be secured to a garment, such as a bra or shirt.
The housing may serve a plurality of additional purposes, including improved conformance of the breast cup 2 to the breast, improved comfort of the portable breast pump system 1, releasable attachment of the breast cup 2 to a garment, and/or blocking the breast from view while using the portable breast pump system 1.
The housing can include a food contact substance. In some embodiments, the housing can include a flexible material, e.g., a polymeric material such as silicone. In some embodiments, the housing can include a rigid material. In some embodiments, the housing can include a fabric (e.g., polyester, cotton, linen, satin, organdy, rayon, taffeta, broad cloth, poplin, velour, gauze, canvas, shirting, muslin, tweed, georgette, crepe, wool, twill, gabardine, denim, or drill). The housing can include polyvinyl chloride (PVC), PTFE (e.g., Teflon), polyethylene, HDPE, LDPE, copolyester (e.g., Tritan EX401), PP, polystyrene, a thermoplastic elastomer, thermoplastic polyurethane, PC, nylon, polyvinylidene fluoride (PVDF), or silicone. In some embodiments, the housing can include a clear material.
Diaphragm
The breast cup 2 may include a diaphragm 18. The diaphragm 18 may separate the pressure chamber 20 from the milk chamber 21.
The diaphragm 18 is configured to deform, i.e., expand, contract, or balloon, under pressure. Upon application of negative pressure to the pressure chamber 20, the diaphragm 18 may deform away from the inlet to the milk chamber 21, opening the inlet to the milk chamber 21. The breast cup 2 including the diaphragm 18 is advantageous in that the configuration may aid in providing fluid flow under pressure, as opposed to exclusively relying on gravity, such that a subject may breast pump in a reclined position.
In some embodiments, the diaphragm 18 includes a flexible material that may stretch upon depressurization and pressurization of the pressure chamber 20. Alternatively, the diaphragm 18 includes a folded, or otherwise shaped, material, that may unfold and refold upon depressurization and pressurization of pressure chamber 20. In some embodiments, the diaphragm 18 includes from 1 to 10 folds (e.g., 1 to 2, 1 to 3, 1 to 4, 1 to 5, 1 to 6, 1 to 7, 1 to 8, 1 to 9, 2 to 3, 2 to 4, 2 to 5, 2 to 6, 2 to 8, 3 to 4, 3 to 5, 3 to 7, 4 to 5, 4 to 6, 4 to 10, 5 to 8, 5 to 10, 8 to 10, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10). In some embodiments, the folded, or otherwise shaped, material is toroidal. In some embodiments, the folded, or otherwise shaped, material may unfold in either direction. In other embodiments, the folded, or otherwise shaped, material may unfold only towards the pressure chamber 20 or milk chamber 21. Flexible and/or folded diaphragms are advantageous in that they allow for expansion with smaller footprints.
In some embodiments, the diaphragm 18 includes a patterned material, such as a plurality of indents or grooves. A diaphragm 18 including a patterned material may be advantageous in optimizing interaction with the pressure chamber 20 and/or the milk chamber 21. In some embodiments, the first portion of the diaphragm 18 includes a plurality of indents and/or grooves. In some embodiments, the first portion of the diaphragm 18, which includes a plurality of indents and/or grooves, can deform more than a second portion of the diaphragm 18 which does not include a plurality of indents and/or grooves.
In some embodiments, the diaphragm 18 includes a material having a Shore hardness from A10 to A80 (e.g., A10, A20, A30, A40, A50, A60, A70, or A80). In some embodiments, the diaphragm 18 includes a material having a Shore hardness from DIO to D80 (e.g., DIO, D20, D30, D40, D50, D60, D70, or D80).
In some embodiments, the diaphragm 18 includes a thickness from about 0.5 mm to about 10 mm (e.g., about 0.5 mm to about 1 mm, about 0.5 mm to about 1.5 mm, about 0.5 mm to about 2 mm, about 0.5 mm to about 2.5 mm, about 0.5 mm to about 5 mm, about 1 mm to about 2 mm, about 1 mm to about 3 mm, about 1 mm to about 4 mm, about 1 mm to about 5 mm, about 1 mm to about 6 mm, about 1 mm to about 7 mm, about 1 mm to about 8 mm, about 1 mm to about 9 mm, about 5 mm to about 10 mm, about 0.5 mm, about 1mm, about 1.5 mm, about 2mm, about 2.5 mm, about 3 mm, about 4 mm, about 5 mm, about 6 mm, about 7 mm, about 8 mm, about 9 mm, or about 10 mm). The diaphragm 18 may have a non-uniform thickness, e.g., with a thicker portion to seal an inlet or at the edge to seal other components.
In some embodiments, the diaphragm 18 is configured to seal the inlet to the milk chamber 21 at sealing point 23. Sealing between the diaphragm 18 and the inlet may be improved through optimization of the Shore hardness, rigidity, thickness, material, surface conditions, and shape of the diaphragm 18.
In some embodiments, the diaphragm 18 varies in thickness and/or Shore hardness. The diaphragm 18 may include a higher thickness and/or higher Shore hardness in the portion of the diaphragm 18 that overlaps with the inlet of the milk chamber 21, e.g., at sealing point 23. In some embodiments, the diaphragm 18 includes a first thickness from about 0.5 mm to about 10 mm (e.g., about 0.5 mm to about 1 mm, about 0.5 mm to about 1.5 mm, about 0.5 mm to about 2 mm, about 0.5 mm to about 2.5 mm, about 0.5 mm to about 5 mm, about 1 mm to about 2 mm, about 1 mm to about 3 mm, about 1 mm to about 4 mm, about 1 mm to about 5 mm, about 1 mm to about 6 mm, about 1 mm to about 7 mm, about 1 mm to about 8 mm, about 1 mm to about 9 mm, about 1 mm to about 10 mm, about 1 mm to about 12 mm, about 1 mm to about 15 mm, about 5 mm to about 10 mm, about 5 mm to about 15 mm, about 5 mm to about 20 mm, about 10 mm to about 15 mm, about 10 mm to about 20 mm, about 15 mm to about 20 mm, about 0.5 mm, about 1 mm, about 1.5 mm, about 2 mm, about 2.5 mm, about 3 mm, about 4 mm, about 5 mm, about 6 mm, about 7 mm, about 8 mm, about 9 mm, about 10 mm, about 11 mm, about 12 mm, about 13 mm, about 14 mm, about 15 mm, about 16 mm, about 17 mm, about 18 mm, about
19 mm, or about 20 mm), and a second thickness from about 0.5 mm to about 10 mm (e.g., about 0.5 mm to about 1 mm, about 0.5 mm to about 1.5 mm, about 0.5 mm to about 2 mm, about 0.5 mm to about 2.5 mm, about 0.5 mm to about 5 mm, about 1 mm to about 2 mm, about 1 mm to about 3 mm, about 1 mm to about 4 mm, about 1 mm to about 5 mm, about 1 mm to about 6 mm, about 1 mm to about 7 mm, about 1 mm to about 8 mm, about 1 mm to about 9 mm, about
1 mm to about 10 mm, about 1 mm to about 12 mm, about 1 mm to about 15 mm, about 5 mm to about 10 mm, about 5 mm to about 15 mm, about 5 mm to about 20 mm, about 10 mm to about 15 mm, about 10 mm to about 20 mm, about 15 mm to about 20 mm, about 0.5 mm, about 1mm, about 1.5 mm, about 2mm, about 2.5 mm, about 3 mm, about 4 mm, about 5 mm, about 6 mm, about 7 mm, about 8 mm, about 9 mm, about 10 mm, about 11 mm, about 12 mm, about 13 mm, about 14 mm, about 15 mm, about 16 mm, about 17 mm, about 18 mm, about 19 mm, or about
20 mm), in which diaphragm 18 includes the second thickness where diaphragm 18 contacts the inlet, e.g., at sealing point 23. In some embodiments, the diaphragm 18 includes a material having a first Shore hardness from A10 to A80 (e.g., A10, A20, A30, A40, A50, A60, A70, or A80) and a second Shore hardness, different from the first, from A10 to A80 (e.g., A10, A20, A30, A40, A50, A60, A70, or A80) or being rigid, in which the material includes the second Shore hardness where diaphragm 18 contacts the inlet, e.g., at sealing point 23. In this embodiment, the second Shore hardness may further range from D10 to D80 (e.g., D10, D20, D30, D40, D50, D60, D70, or D80) or be rigid.
In some embodiments, the diaphragm 18 includes a curved shape, such that the surface of the diaphragm 18 curves over and around the inlet to the milk chamber 21. In some embodiments, the diaphragm 18 includes a parabolic shape on the side of the diaphragm that contacts the inlet. In some embodiments, the diaphragm 18 may have a cup or cone shape.
In some embodiments, the diaphragm 18 includes a plurality of layers, e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. In some embodiments, the diaphragm 18 includes a plurality of layers in which the diaphragm 18 contacts the inlet, e.g., at sealing point 23. In some embodiments, a second layer is over molded over a first layer of the diaphragm 18. The first layer and/or second layer may be a flexible or rigid material. In some embodiments, the first layer is a rigid material, and the second layer is a flexible material. This embodiment may be advantageous in sealing the inlet, such that the rigid material maintains coverage of the entire inlet, while the flexible material aids in sealing the sealing point 23. The first layer may be a disk and/or may include a ring or lip to aid in sealing. Alternatively, the first layer may be a cup- or cone-shaped layer over molded or embedded into the diaphragm 18. In some embodiments, the cup- or cone-shaped layer is configured to cap the inlet to the milk chamber 21, e.g., at sealing point 23. A plurality of layers may aid in decreasing deflection and improving sealing performance at the point where the diaphragm 18 contacts the inlet of the milk chamber, e.g., at sealing point 23. In some embodiments, all or a portion of the diaphragm may be clear. In some embodiments, a clear portion may be configured to seal the inlet to the milk chamber 21, e.g., at the sealing point 23, and may provide a visual line of sight from the outside of the diaphragm 18 to the nipple tunnel 13. In this embodiment, the clear portion may contain a lens, wherein the lens allows for magnification. A visual line of sight to the nipple chamber may aid the user in centering the breast shield 19 on the nipple during a pumping session.
In some embodiments, the diaphragm 18 is shaped to conform to the shape of the breast shield 19, e.g., upon compression of the milk chamber 21. In some embodiments, the diaphragm 18 is not configured to contact the inlet, e.g., at sealing point 23. In some embodiments, the fitting is a plug or a cover. In some embodiments, the diaphragm 18 is configured to actuate a valve 24.
The diaphragm 18 can include a food contact substance. The diaphragm 18 can include polyvinyl chloride (PVC), polyethylene, PP, polystyrene, a thermoplastic elastomer, thermoplastic polyurethane, PC, nylon, polyvinylidene fluoride (PVDF), or silicone. The diaphragm 18 can include a flexible material, e.g., formed from a polymeric material such as silicone. The diaphragm 18 can include a rigid material.
Milk Chamber
The breast cup 2 can include the milk chamber 21, which is configured to temporarily hold a volume of milk that is expressed from a nipple. The milk chamber 21 includes an inlet and an outlet 22.
In some embodiments, the milk chamber 21 is reversibly attached to the breast cup 2. In some embodiments, the milk chamber 21 is reversibly attached to the breast cup 2, such that smaller or larger milk chambers 21 may be reversibly attached to the breast cup 2. The milk chamber 21 can have a volume, nominal or expanded, from about 1 mL to about 150 mL (e.g., about 1 mL to about 10 mL, about 1 mL to about 25 mL, about 1 mL to about 50 mL, about 1 mL to about 75 mL, about 1 mL to about 100 mL, about 25 mL to about 50 mL, about 25 mL to about 100 mL, about 50 mL to about 150 mL, about 100 mL to about 150 mL, about 1 mL, about 5 mL, about 10 mL, about 15 mL, about 20 mL, about 25 mL, about 30 mL, about 40 mL, about 50 mL, about 60 mL, about 70 mL, about 75 mL, about 80 mL, about 90 mL, about 100 mL, about 125 mL, or about 150 mL). The milk chamber 21 can have a maximum volume, nominal or expanded, from about 1 mL to about 150 mL (e.g., about 1 mL to about 10 mL, about 1 mL to about 25 mL, about 1 mL to about 50 mL, about 1 mL to about 75 mL, about 1 mL to about 100 mL, about 25 mL to about 50 mL, about 25 mL to about 100 mL, about 50 mL to about 150 mL, about 100 mL to about 150 mL, about 1 mL, about 5 mL, about 10 mL, about 15 mL, about 20 mL, about 25 mL, about 30 mL, about 40 mL, about 50 mL, about 60 mL, about 70 mL, about 75 mL, about 80 mL, about 90 mL, about 100 mL, about 125 mL, or about 150 mL). In some embodiments, the milk chamber 21 has a nominal volume of less than about 10 mL (e.g., less than about 5 mL, less than about 4.5 mL, less than about 4 mL, less than about 3.5 mL, less than about 3 mL, less than about 2.5 mL, less than about 2 mL, less than about 1.5 mL, less than about 1 mL, less than about 0.5 mL, or less than about 0.1 mL). In some embodiments, the milk chamber 21 has a nominal volume of about 30 mL.
In some embodiments, the diaphragm 18 seals the inlet to the milk chamber 21 before positive pressure, e.g., at ambient pressure, is applied to pressure chamber 20 and the milk chamber 21 is compressed, e.g., at sealing point 23. In some embodiments, the seal between the diaphragm 18 and the inlet to the milk chamber 21 has greater sealing pressure than the resistance of one directional valve 15 on the outlet 22 of the milk chamber 21.
As described herein, the milk chamber 21 may be formed by the space between the breast shield 19 and the diaphragm 18 or between one or more additional layers between the diaphragm 18 and the breast shield 19.
The milk chamber 21 may include an outlet 22. The outlet 22 may include a one directional valve 15, e.g., to prevent air or expressed milk from being drawn back into the milk chamber 21 during milk expression. The valve opens to allow milk to flow out of the milk chamber 21. In some embodiments, the one directional valve 15 is passively actuated by pressure changes in the milk chamber 21. The milk chamber 21 may also include an inlet, e.g., as a vent or to allow additional fluids, e.g., cleaning fluids or positive pressure to enter. Milk Chamber Wall
The breast cup 2 may include a milk chamber wall 26.
While in some embodiments, the milk chamber 21 is defined between the diaphragm 18 and the breast shield 19, the milk chamber 21 can alternatively be defined between the diaphragm 18 and the milk chamber wall 26, e.g., as shown in FIG. 7. Thus, in some embodiments, the milk chamber wall 26 is disposed between the diaphragm 18 and the breast shield 19, thereby defining the milk chamber 21 between the diaphragm 18 and the milk chamber wall 26. The milk chamber wall is advantageous, in that it can provide additional structural stability to the milk chamber.
In some embodiments, the milk chamber wall 26 can include a curved shape or a cupshape.
In some embodiments, the milk chamber wall 26 is removably attached to the breast cup 2. In some embodiments, the milk chamber wall 26 is snapped into the breast cup 2. In some embodiments, the milk chamber wall 26 can be inserted into the breast cup 2 to reduce the volume of the milk chamber 21.
In some embodiments, the milk chamber wall 26 includes an orifice 25 for outlet 22.
In some embodiments, the milk chamber wall 26 can include polyethylene terephthalate (PET), polypropylene (PP), polyethylene, high-density polyethylene (HDPE), low-density polyethylene (LDPE), or polycarbonate (PC). The milk chamber 21 wall may include a clear material.
Pressure Chamber
The breast cup 2 can include the pressure chamber 20, which is configured to expand and compress the diaphragm 18 in order to express milk from a nipple.
In some embodiments, the pressure chamber 20 is reversibly attached to the breast cup 2.
The pressure chamber 20 can have a maximum volume from about 1 mL to about 150 mL (e.g., about 1 mL to about 10 mL, about 1 mL to about 15 mL, about 1 mL to about 20 mL, about 1 mL to about 25 mL, about 1 mL to about 50 mL, about 1 mL to about 75 mL, about 1 mL to about 100 mL, about 5 mL to about 10 mL, about 5 mL to about 15 mL, about 5 mL to about 20 mL, about 5 mL to about 25 mL, about 5 mL to about 50 mL, about 10 mL to about 15 mL, about 10 mL to about 20 mL, about 10 mL to about 25 mL, about 10 mL to about 30 mL, about 10 mL to about 50 mL, about 15 mL to about 20 mL, about 15 mL to about 25 mL, about 15 mL to about 30 mL, about 15 mL to about 50 mL, about 20 mL to about 25 mL, about 20 mL to about 30 mL, about 20 mL to about 50 mL, about 25 mL to about 50 mL, from about 25 mL to about 100 mL, from about 50 mL to about 150 mL, from about 100 mL to about 150 mL, about 1 mL, about 5 mL, about 6 mL, about 7 mL, about 8 mL, about 9 mL, about 10 mL, about 11 mL, about 12 mL, about 13 mL, about 14 mL, about 15 mL, about 16 mL, about 17 mL, about 18 mL, about 19 mL, about 20 mL, about 25 mL, about 30 mL, about 40 mL, about 50 mL, about 60 mL, about 70 mL, about 75 mL, about 80 mL, about 90 mL, about 100 mL, about 125 mL, or about 150 mL). The pressure chamber 20 may have a maximum volume of about 45 mL.
In some embodiments, the pressure chamber 20 limits the shape of the diaphragm 18 at the maximum deflection of the diaphragm 18, thus restricting the maximum negative pressure that can be applied to the nipple.
In some embodiments, upon application of positive pressure, the diaphragm 18 moves towards its nominal position and extends past it under pressure to conform to the shape of the milk chamber 21, thus transporting all liquid through the outlet 22.
In some embodiments, the pressure chamber 20 further includes a valve to the ambient atmosphere. In some embodiments, the valve is an inflation valve. In some embodiments, the volume of the pressure chamber 20 may be set with the inflation valve. In some embodiments, the valve is a relief valve. The relief valve may be configured to release pressure from the pressure chamber 20 if the positive pressure exceeds a maximum positive pressure, or if the negative pressure exceeds a maximum negative pressure.
While in some embodiments, the volume of the pressure chamber 20 may be set with an inflation valve, the volume of the pressure chamber 20 may be set in a variety of manners. In some embodiments, the pressure chamber 20 is reversibly attached to the breast cup 2, such that smaller or larger pressure chambers 20 may be reversibly attached to the breast cup 2. In some embodiments, the breast cup 2 includes a plug, which may be configured to be inserted into the pressure chamber 20 to reduce the volume. In some embodiments, the volume of the pressure chamber 20 may be adjusted manually by the user such that it sits farther or closer to the chest of the user.
The pressure chamber 20 can be returned to ambient pressure following a breast pumping session.
The pressure chamber 20 includes one or more inlets to allow for changes in pressure. The pressure chamber 20 or housing may include a limiter that controls the maximum volume of the pressure chamber 20, e.g., to determine the pressure limit. For example, the breast shield may include a bladder or other element that can be filled with air or other fluid, e.g., water, and disposed to reduce the volume available for expansion of the pressure chamber 20. Control Unit
In some embodiments, the portable breast pump system 1 may include a control unit. The control unit may include or be implemented by one or more computers, microcomputers or microprocessors. The one or more computers may be configured to individually or collectively, e.g., in a distributed manner, carry out operations, e.g., in accordance with programmed instructions stored in a memory (e.g., a non-volatile memory) and executed by one or more processors. The control unit provides instructions, e.g., pre-programmed instructions or instructions provided by an external computer. The pre-programmed instructions or instructions provided by an external computer may be pumping instructions, heating instructions, cooling instructions, time instructions, etc. For example, the control unit can be configured to (i) send a signal to the valve 24 to open and close or (ii) send a signal to change the pressure in the pressure source 9.
Pumping in Public
Current commercially available breast pumps are not equipped to allow women to perform all steps of a breast pumping session in a public place, such as a park, stadium, or restaurant. Firstly, the majority of pumps are electric, and require access to a working power outlet to function. A working outlet may not be accessible in many locations, such as in a park or on an airplane. Second, portable pumps that are powered either by batteries or manual expression typically have large profiles, where the breast cup 2 is attached directly to the reservoir 3 or milk bottle, such that they protrude directly perpendicular to the user’s chest. These pumps cannot be used with any discretion, as clothing, e.g., a shirt or blouse, must be removed to utilize the pumps. Additionally, these pumps often lack the power required to fully express all the milk in a user’s breast. Thirdly, no portable pump exists for off-body milk collection. A pump with on-body milk collection requires the milk to stay in the pumping unit until the whole unit is removed. For an in-bra pump, the user would have to remove the entire pump to access the milk, and leaving the pump in place after a pumping session may lead to potentially spoiled milk and leaks.
Beneficially, the portable pump units described herein (e.g., the pump unit 6 described above, as well as the pump unit 106 described below) solve these problems by including an integrated, on-board power source (e.g., the power source 112) that eliminates the need for a power outlet and stores pumped milk within an off-body storage component (e.g., the reservoir 3 or the reservoir 103) that may be removed without accessing the breast cup 2. Alternative Pump unit
Referring now to FIGS. 10-19, an alternative portable pump unit 106 is shown, according to an example embodiment. It should be appreciated that the portable pump unit 106 may include any of the various components and/or functionalities of the portable pump unit 6 described above. Similarly, any of the various components and/or functionalities of the portable pump unit 106 described below may be applied to the portable pump unit 6 described above. Each of these variations is contemplated herein and is within the scope of the present disclosure. Furthermore, the portable pump unit 106 is similarly configured to be used with, connected to (e.g., fluidly coupled to), and/or otherwise adapted to function with the breast cups 2, reservoir enclosures 4 (e.g., the separate reservoir enclosure 4 shown in FIG. 3 and/or the wearable reservoir enclosure 4 shown in FIG. 2), and/or any other suitable components of the portable breast pump system 1 described herein.
As best illustrated in FIGS. 10 and 11, the portable pump unit 106 includes a removable pumping unit 101, a portable reservoir adapter 102, a portable reservoir 103, and a portable pump unit coupler 104. The removable pumping unit 101 is configured to selectively provide positive and/or negative pressure to the breast cup 2 to induce lactation and, ultimately, force lactated milk from the breast cup 2 into the portable reservoir 103 via fluid conduit lines 105. It will be understood that the fluid conduit lines 105 may be substantially similar or the same as the fluid conduit lines 5 discussed above, and may be used in combination with or instead of the fluid conduit lines 5. In some instances, the fluid conduit lines 105 are the only thing coupling the portable pump unit 106 to the breast cup 2.
For example, the removable pumping unit 101 includes a pressure source 107 (e.g., a pump) fluidly coupled to a manifold 108 (e.g., via various fluid conduit lines). The manifold
108 includes a number of solenoid valves 109 configured to selectively direct positive and negative pressure from the pressure source 107 through a pumping unit outlet 110. The pumping unit outlet 110 is configured to receive a pumping unit port 113 of the portable pump unit coupler 104 to fluidly couple the pumping unit outlet 110 to the pressure chamber 20 of the breast cup 2 via a fluid conduit line 105.
The removable pumping unit 101 further includes a processing circuit or controller 111 configured to selectively activate and actuate the pressure source 107 and the solenoid valves
109 to selectively direct the positive and negative pressure from the pressure source 107 to the breast cup 2. For example, the processing circuit or controller 111 may include one or more processors and one or more memories storing instructions thereon that, when executed by the one or more processors, cause the one or more processing circuits to perform the various functions described herein.
In some instances, the processing circuit or controller 111 may further include one of more communication interfaces configured to allow the processing circuit or controller 111 to communicate with other devices over a communications network (e.g., Bluetooth, Wi-Fi, near- field communication, etc.). Additionally, in some instances, the processing circuit or controller 111 may include one or more input/output (I/O) devices 119 configured to allow user to selectively operate the removable pumping unit 101 and/or modify the functionality parameters of the removable pumping unit 101. For example, the one or more I/O devices may include a display, one or more buttons (e.g., a power button, a pumping session start/stop button), a touchscreen, an audio speaker, a timer, an alarm, a power switch, and/or any other suitable I/O devices.
The removable pumping unit 101 further includes a power source 112 (e.g., a battery). In some instances, the power source 112 may be rechargeable via connection with an external power source (e.g., a wall outlet). In some other instances, the removable pumping unit 101 may be configured to allow for the removal and replacement of the power source 112 upon depletion of its power.
In some embodiments, the removable pumping unit 101 is removably coupled to the portable reservoir adapter 102 via any of a threaded connection, a snap-fit connection, a latchbased connection, or any other suitable releasable connection method. The portable reservoir adapter 102 includes a reservoir inlet 114 configured to receive a reservoir port 115 of the portable pump unit coupler 104 to fluidly couple the reservoir inlet 114 (and thus an internal cavity 116 formed within and between the portable reservoir adapter 102 and the portable reservoir 103) to the milk chamber 21 of the breast cup 2 via a fluid conduit line 105.
In some embodiments, the portable reservoir adapter 102 is removably coupled to the portable reservoir 103 via any of a threaded connection, a snap-fit connection, a latch-based connection, or any other suitable releasable connection method. Further, while shown as separate components, in some instances, the portable reservoir adapter 102 and the portable reservoir 103 may be formed as a single integrated component.
The portable pump unit coupler 104 is configured to releasably and fluidly couple the pumping unit outlet 110 and the portable reservoir inlet 114 of the portable reservoir adapter 102 to the fluid conduit lines 105 coupled to the breast cup 2. That is, with the removable pumping unit 101 coupled to the portable reservoir adapter 102, and the portable reservoir adapter 102 coupled to the portable reservoir 103, the portable pump unit coupler 104 is configured to be attached between the removable pumping unit 101 and the portable reservoir adapter 102 by inserting the pumping unit port 113 into the pumping unit outlet 110 and by inserting the reservoir port 115 into the portable reservoir inlet 114. With the portable pump unit coupler 104 attached between the removable pumping unit 101 and the portable reservoir adapter 102, pressure may be selectively applied by the removable pumping unit 101 (e.g., the pressure source 107) to the pressure chamber 20 of the breast cup 2 to induce lactation from the human breast, as described herein. Further, milk pulled into the milk chamber 21, as described herein, is able to flow from or is otherwise forced out of the milk chamber 21 and into the portable reservoir 103. In some instances, to allow for multiple pumping sessions, the portable reservoir 103 may be removed and replaced with a second portable reservoir 103 that is similar or identical to the portable reservoir 103.
In some instances, the portable pump unit 106 may include one or more carrying features. For example, in some instances, the portable pump unit 106 may include a handle 117 for holding and/or carrying the portable pump unit 106. Similarly, in some instances, the portable pump unit 106 may additionally or alternatively include an attachment feature 118, such as a clip, a strap, a hook, a zipper, a magnet, a pin, a button, a snap, a hook and loop fastener (e.g., VELCRO®), or a combination thereof, may be attached to the portable pump unit 106, such that the portable pump unit 106 may be releasably attached, e.g., clipped to the clothing (e.g., a belt, a bra) or other items (e.g., a backpack) of the user.
In some instances, the portable pump unit 106 may further include one or more sensors 120. For example, in some instances, one or more sensors 120 are within the portable reservoir 103 (e.g., arranged near or at the bottom of the portable reservoir 103) that are configured to communicate various sensor data captured within the portable reservoir 103 to the processing circuit or controller 111 via a wired or wireless connection. For example, in some instances, the one or more sensors 120 are configured to detect, sense, or otherwise measure one or more of a weight, a temperature, a pH, a viscosity, optical characteristics, or any other relevant information regarding milk stored within the portable reservoir 103. In some other instances, the portable pump unit 106 may include one or more additional sensors located in other portions of the portable pump unit 106 (e.g., within the manifold 108, within the pumping unit outlet 110, within the portable reservoir inlet 114) that are configured to sense, detect, or otherwise measure the same or additional operational characteristics, such as a pressure being produced by the pressure source 107, a volume and/or flowrate of milk flowing into the portable reservoir 103, and/or any other desired information pertaining to the portable pump unit 106.
Accordingly, during operation of the portable pump unit 106 within the portable breast pump system 1, the removable pumping unit 101 may be activated to apply alternating pressure (e.g., alternating negative and nominal pressure or alternating negative and positive pressures) to the pressure chamber 20 of the breast cup 2. The alternating pressures applied to the pressure chamber 20 are configured to deform the diaphragm 18 to alternatingly (i) expand the milk chamber 21 and unseal the sealing point 23 around the inlet to the milk chamber 21 to allow milk expressed from the human breast to flow into the milk chamber 21 and (ii) contract the milk chamber 21 and seal the sealing point 23 around the inlet to the milk chamber 21 such that the expressed milk within the milk chamber 21 is forced out of the breast cup 2, through fluid conduit lines (e.g., fluid conduit lines 105), and ultimately into the portable reservoir 103.
It should be appreciated that, unlike traditional breast pumps, the milk may be collected within the portable reservoir 103 of the portable pump unit 106 while the portable pump unit 106 is located away from the breast cup 2. That is, the portable pump unit 106 is connected to the breast cup 2 via fluid conduit lines (e.g., fluid conduit lines 5 or fluid conduit lines 105) that extend a distance away from the breast cup 2 (e.g., at least a foot, at least two feet, at least three feet, at least four feet) to allow for the milk to be collected off of the user’s body. This off-body milk pumping and collection provides three distinct benefits over traditional systems: (1) the size of the breast cup 2 may be significantly reduced compared to a system in which a reservoir is attached to or otherwise integrated within the breast cup to allow for on-body milk storage; (2) the milk can be removed from the reservoir 103 without needing to remove the breast cup 2 from the user’s breast or even needing to access the user’s shirt or bra; and (3) noise created by the pressure source 107 is not emitted from within the user’s shirt or bra (e.g., it is instead emitted from an off-body location where the portable pump unit 106 is located). These features allow the user to more privately and inconspicuously pump and access pumped milk while in public.
In some instances, the diaphragm 18 returning to a nominal state may provide sufficient force on the milk within the milk chamber 21 to force the milk out of the milk chamber 21 and into the portable reservoir 103. However, in some instances, the portable pump unit 106 may apply positive pressure to the pressure chamber 20 to further contract the milk chamber 21, and thereby force the milk out of the milk chamber 21 and into the portable reservoir 103. In some instances, negative pressure may be applied from the pressure source 107 via another fluid conduit 121 in the removable pumping unit 101 and the portable pump unit coupler 104 to the milk chamber 21 to pull or suction the milk out of the milk chamber 21. However, to prevent a direct connection between the dry side and wet side of the pump system, a membrane diaphragm or another similar device may be utilized to apply the negative pressure from the pressure source 107 to the milk chamber 21. In some instances, the portable reservoir 103 may include a vent hole or pressure outlet 122 (e.g., a pressure relieve valve) configured to allow pressurized air to escape from within the portable reservoir 103 to prevent excessive pressure build-up and/or to allow for milk to more easily flow into the portable reservoir 103.
In some instances, the user may then remove the portable reservoir 103 from the portable pump unit 106 to access the stored milk without removing the breast cup 2 from their breast. For example, the user may simply unscrew or otherwise decouple the portable reservoir 103 from the portable reservoir adapter 102 to access the milk stored within the portable reservoir 103 while the breast cup 2 is still attached to the breast of the user.
Connector Set with Clamping Member
The present disclosure additionally provides a connector set including a clamping member that activates when the set is disconnected for use with any of the fluid conduits and/or other fluid connections described herein. The connector set offers a solution that ensures that the liquid lumen is closed off from ingress whilst removing any additional parts from the fluid path. This mechanism may be housed within a body and may be releasable by pressing a single button that allows the user to release the clamp and lock the lumens into place. When connected, the clamping member is deactivated, and the lumens are fluidically connected.
Advantageously, the connector set employs mechanical force via a biasing member allowing for a lower profile and requiring no electrical power or control. The connector set is also advantageous as no additional parts are in the fluid path, it is simple to operate via a single button, the tubing can be replaceable, and the parts can be washable.
Furthermore, although discussed in the context of breast pumping, the present connector set may be used for any purpose where liquids are transported, especially where it is desirable to reduce or eliminate contamination upon disconnection, e.g., in other foods and beverages, or medical treatment.
A connector set of the disclosure includes two interlocking members. Each interlocking member includes a body having at least one lumen therein and a port. When the bodies of the set are disconnected, a biasing member disposes a clamping member to fluidically disconnect the lumen from the port. When the bodies of the set are connected, they form a fluid tight seal that fluidically connects the lumens in each member via the ports. The act of connecting the bodies displaces the clamping member from the lumen.
The bodies may include any number of lumens to be connected. Furthermore, when more than one lumen is present in one body, it may connect to a single other body having the same or fewer corresponding lumens or multiple other bodies, e.g., a separate body for each lumen. In some embodiments, one or both of the bodies may include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more lumens, preferably 1 or 2. In some embodiments, the lumen is separated from the clamping member by a layer, e.g., of an elastic polymer. This layer may be the wall of tubing inserted within the body. Alternatively, a layer may be a flexible membrane that separates the clamping member from the lumen, which may be otherwise bound by the body itself. The ports may be connected by any suitable means to form a fluid tight seal. For example, one port may have a male fitting and the other port may have a female fitting that seals upon connection of the bodies. The bodies may be keyed so that they can be connected in only one orientation, e.g., when more than one lumen is present. Any suitable key may be employed, e.g., corresponding shapes or a projecting member and a corresponding groove.
The clamping member includes or interacts with a biasing member to open and close the lumen, e.g., by lateral or axial force. For example, the biasing member may cause the clamping member to force the walls of tubing together sufficiently to fluidically disconnect the lumen from the port. Examples of biasing members include a spring (e.g., coil or leaf) and an elastomeric material (such as a reversibly compressible polymer or foam). The biasing member may also be a compliant mechanism component of the clamping member. The clamping member may be of any suitable shape to seal the lumen. For example, the clamping member may include a pinch point. Displacement of the clamping member may occur by any suitable mechanical means. For example, the clamping member may be slidably disposed in the body, where the connection of the bodies linearly displaces the clamping member and compresses the biasing member. Displacement of the clamping member may occur by the physical action of one body being connected to the other. For example, the clamping member may include (or be connected to) a block that can be slid within a body by the connection with the other body. As the other body displaces the block, the biasing member compresses, and the clamping member is released from the lumen. Multiple blocks may be present, e.g., when a body includes more than one lumen. When more than one block is present, the additional blocks may or may not be associated with further clamping members (e.g., similar to clamping member). In another embodiment, the clamping member may include (or be connected to) a protruding member that extends beyond the exterior of the body. When the protruding member is inserted into a recess in the other body, the body displaces the protruding member to compress a biasing member, and the clamping member is released from the lumen. When the bodies disconnect, the operation is reversed, and the clamping member again seals the lumen. Each lumen in each body may or may not have a corresponding clamping member. That is, some lumens may be open to the atmosphere when the bodies are disconnected.
The bodies may be held together by a locking mechanism or by any other means, e.g., shape or friction. A locking member may be disposed in one body and engage when connected to the other body, holding the two bodies together. The locking member may be part of the clamping member or a block used to displace the clamping member. For example, the body that displaces the block may include a recess shaped to fit the block once the bodies are connected. The block within the recess then prevents disconnection until a release mechanism is employed. For example, further compressing the biasing member, e.g., by a button connected thereto, may be used to displace the block from the recess to allow for disconnection. Other locking members may also be released via compression of the biasing member. Other locking members separate from the clamping member or blocking member may be employed, such as Luer and other connectors or a spring-loaded bearing, which would employ physical force to disconnect the bodies. The locking member may also be configured to release above a preset pressure threshold.
Bodies, clamping members (e.g., the clamping member), and locking members may include any suitable material, e.g., plastic or metal. Typically, the bodies, clamping members (e.g., the clamping member), and locking members will include materials more rigid than the tubing. In addition, the various components for movement of the clamping member, e.g., biasing member, block, and locking member, may or may not be integral. It should be understood that these components may be present as separate, mechanically connected components. Various components may also be shaped to allow for carrying out the functions of the connector set. For example, the pinch point of a clamping member may be wedge shaped to maximize pressure applied to tubing or a membrane. Blocks, protruding members, locking members, recesses, and bodies may also be shaped to reduce mechanical friction during use, e.g., by being angled or rounded to allow for smooth operation of the connector set.
Tubing may be secured in the body by any means, e.g., adhesive, gasket, clamp, friction fit, or connector, such as a Luer connector or a tab feature that interlocks with a recess.

Tubing may have any appropriate connector at the end distal to the connector set, e.g., for connection to a breast cup of a breast pump or a reservoir for milk. Examples of connectors include Luer connectors, threaded connectors, and slip fit connectors.
FIGS. 20A and 20B illustrate one embodiment of a connector set 200. The set 200 includes a female first interlocking member 202 and a male second interlocking member 204. Each body includes two lumens 206 within the tubing. In this embodiment, the first and second lumens connect and can be used to transport milk from a breast cup into a breast cup, and the third and fourth lumens connect and can be used to provide or release pressure to the breast cup, e.g., for breast pumping. This set includes two clamping members 208 in each body, each having a pinch point 210 to seal the tubing. As shown, the biasing member 212 in the first body 214 is integral with the clamping member 208 and block 216. Insertion of the second body into the first body 214 causes the second body 218 to displace the block 216, which in turn compresses the biasing member 212 and releases the clamping member 202 (as shown in the lower panel). The block 216 fits into a recess 220 in the second body 218 to act as a locking member. Clamping members 202 on the second body 218 are similarly displaced by the first body 214 displacing a protruding member 222 on the outside of the second body 218. The connector set 200 can be released by compressing a button or release latch 224 on the exterior of the first body 214. Pressing the latch 224 further compresses the first biasing member 222 and displaces the block 216 from the recess 220 to allow for disconnection.
FIGS. 21A and 21B illustrate another embodiment of a connector set 300. The set 300 includes a female first interlocking member 302 and a male second interlocking member 304. Each body includes two lumens 306 within the tubing. In this embodiment, the first and second lumens connect and can be used to transport milk from a breast cup to a milk reservoir, and the third and fourth lumens connect and can be used to provide or release pressure to the breast cup, e.g., for breast pumping. This 300 set includes one clamping member 308 in each body, each having a pinch point 310 to seal the tubing. The other two lumens remain open when the bodies are disconnected. As shown, the biasing members 312 are springs. The first clamping member 302 is integral to the two blocks. Insertion of the second body 318 into the first body 314 causes the second body 318 to displace the blocks 316, which in turn compresses the biasing member 312 and releases the clamping member 302 (as shown in the lower panel). The blocks 316 fit into a recess 320 in the second body 318 to act as locking members. Clamping members 302 on the second body 318 are similarly displaced by the first body 314 displacing a protruding member 322 on the outside of the second body 318. The connector set 300 can be released by compressing a button or release latch 324 on the exterior of the first body 314. Pressing the latch 324 further compresses the first biasing member 312 and displaces the blocks 316 from the recesses 320 to allow for disconnection.
In some embodiments, a connector set comprises first and second interlocking members, wherein the first interlocking member comprises a first body having a first lumen therein, a first port, a first clamping member, and a first biasing member; and the second interlocking member comprises a second body having a second lumen therein, and a second port, wherein the first and second bodies connect to form a fluid tight seal that fluidically connects the first and second lumens via the first and second ports, wherein when the first and second bodies are disconnected, the first biasing member disposes the first clamping member to fluidically disconnect the first lumen from the first port, and wherein the second body displaces the first clamping member from the first lumen upon connection.
In some embodiments, the first interlocking member further comprises a first layer disposed between the first lumen and the first clamping member. In some embodiments, a first tubing comprises the first layer, and a second tubing comprises the second lumen. In some embodiments, the first tubing comprises a distal end opposite the first port and the second tubing comprises a distal end opposite the second port, wherein one of the distal end of the first tubing and the second tubing is connected to a breast cup, and the other distal end is connected to a milk reservoir. In some embodiments, the second body further comprises a second clamping member and a second biasing member, wherein when the first and second bodies are disconnected, the second biasing member disposes the second clamping member to fluidically disconnect the second lumen from the second port, and wherein the first body displaces the second clamping member from the second lumen upon connection. In some embodiments, the first interlocking member further comprises a first locking member that engages the second body upon connection with the first body. In some embodiments, the first locking member is released by further compressing the first biasing member. In some embodiments, the first interlocking member further comprises a block, wherein the second body engages the block to compress the first biasing member to displace the first clamping member. In some embodiments, the block and first clamping member are slidably disposed within the first body. In some embodiments, the first body further comprises a third lumen and a third port and the second body further comprises a fourth lumen and a fourth port, wherein the first and second bodies connect to form a fluid tight seal that fluidically connects the third and fourth lumens via the third and fourth ports.

The present disclosure provides improved methods of breast pumping.
The present disclosure provides a method of breast pumping by: (i) providing a portable breast pump system 1; (ii) contacting a human breast with the breast cup; and (iii) applying an alternating first pressure and second pressure such that milk is moved from the human breast to the reservoir 3 (or the reservoir 103), in which the first pressure and the second pressure are functions of a negative pressure and a positive pressure. The breast pumping system is optionally mobile before, during, and/or after pumping.
In some embodiments, the method includes picking up and/or holding the pump unit 6 (or the pump unit 106) before, during, and/or after the pumping session. In some embodiments, the method further includes releasably attaching the pump unit 6 (or the pump unit 106) to a subject prior to, during, and/or after completion of a pumping session, e.g., via a strap, belt, or fastener. In some embodiments, the method further includes the subject pumping while moving, reclining, resting, sleeping, or traveling.
In some embodiments, the method includes recharging the power source in the pump unit 6 (or the pump unit 106). In some embodiments, the method includes replacing batteries in the pump unit 6 (or the pump unit 106).
In some embodiments, the method includes a first pumping session and a second pumping session, wherein the breast cups 2 are not removed between the first pumping session and the second pumping session. In some embodiments, the breast cups 2 are removed between the first pumping session and the second pumping session.
In some embodiments, the method further includes releasably securing a reservoir 3 in the pump unit 6 (or the portable reservoir 103 to the remaining components of the pump unit 106).
In some embodiments, the method includes releasably securing a reservoir 3 in the pump unit 6 (or the portable reservoir 103 to the remaining components of the pump unit 106); providing a fluidic connection between the breast cup 2 and the reservoir 3; and pumping the human breast such that milk is expressed into the breast cup 2 and travels through the fluid conduit 5 to the reservoir 3. In some embodiments, the method further includes removing the reservoir 3 from the pump unit 6 (or the portable reservoir 103 from the remaining components of the pump unit 106) after the conclusion of the pumping session, and, e.g., placing the reservoir in a fridge 28, freezer 30, secondary reservoir enclosure 4, disposing of the milk in the reservoir, or feeding the milk in the reservoir to a child.
In some embodiments, the method includes securing the breast cup 2 to a human breast; releasably securing a first reservoir 3 in the pump unit 6 (or a first reservoir 103 to the remaining components of the pump unit 106); providing a fluidic connection between the breast cup 2 and the first reservoir 3 (or the first reservoir 103 to the remaining components of the pump unit 106); performing a first pumping session, such that expressed milk travels from the breast cup 2 into the first reservoir 3 (or the first reservoir 103); removing the first reservoir 3 (or the first reservoir 103) from the pump unit 6 (or the pump unit 106); installing a second reservoir 3 (or a second reservoir 103) in the pump unit 6 (or to the remaining components of the pump unit 106); and pumping in a second pumping session, such that expressed milk travels from the breast cup 2 into the second reservoir 3 (or the second reservoir 103). In some embodiments, the first reservoir 3 (or the first reservoir 103) is releasably secured in the pump unit 6 (or to the pump unit 106) prior to securing the breast cup 2 on the human breast.
In some embodiments, the time between one breast pumping session and another breast pumping session (e.g., between a first breast pumping session and a second breast pumping session, a second breast pumping session and a third breast pumping session, a third breast pumping session and a fourth breast pumping session, etc.) is from about 30 minutes to about 240 minutes (e.g., about 30 minutes to about 45 minutes, about 30 minutes to about 60 minutes, about 30 minutes to about 90 minutes, about 30 minutes to about 120 minutes, about 30 minutes to about 180 minutes, about 45 minutes to about 60 minutes, about 45 minutes to about 90 minutes, about 45 minutes to about 120 minutes, about 60 minutes to about 90 minutes, about 60 minutes to about 120 minutes, about 50 minutes to about 180 minutes, about 60 minutes to about 210 minutes, about 90 minutes to about 120 minutes, about 90 minutes to about 180 minutes, about 90 minutes to about 210 minutes, about 90 minutes to about 240 minutes, about 120 minutes to about 180 minutes, about 120 minutes to about 210 minutes, about 120 minutes to about 240 minutes, about 180 minutes to about 210 minutes, about 180 minutes to about 240 minutes, about 210 minutes to about 240 minutes, about 30 minutes, about 45 minutes, about 60 minutes, about 85 minutes, about 90 minutes, about 105 minutes, about 120 minutes, about 135 minutes, about 150 minutes, about 165 minutes, about 180 minutes, about 195 minutes, about 210 minutes, about 225 minutes, or about 240 minutes). In some embodiments, the portable breast pump system 1 may enter a waiting phase between breast pumping sessions where the breast cup 2 is not in fluidic communication with any reservoir 3 (or any reservoir 103). In some embodiments, following a breast pumping session, the portable breast pump system 1 places the breast cup 2 in fluidic communication with a second reservoir 3 (or a second reservoir 103). The second reservoir 3 (or the second reservoir 103) may be empty.
In some embodiments, milk from the first breast pumping session is transported to a first reservoir, and milk from the second breast pumping session is transported to a second reservoir. Likewise, milk from a third, fourth, fifth, sixth, seventh, eighth, ninth, or tenth breast pumping session may be transported into a third, fourth, fifth, sixth, seventh, eighth, ninth, or tenth reservoir, respectively. In some embodiments, the method includes removing fluidic communication between the breast cup 2 and all of the reservoirs 3 (or all of the reservoirs 103) between breast pumping sessions. In some embodiments, a plurality of valves is closed to remove fluidic communication between the breast cup 2 and all of the reservoirs 3 (or all of the reservoirs 103). Once full, a reservoir may be removed and replaced with an empty reservoir.
The method may further include assembling the portable breast pump system 1. In some embodiments, the method includes releasably connecting at least one fluid conduit 5 to the pump unit 6 (or the pump unit 106), the pump housing (or the removable pumping unit 101), or the pump system (or the pressure source 107) directly. In some embodiments, the method further includes releasably connecting at least one fluid conduit 5 to the breast cup 2. In some embodiments, the method includes releasably connecting at least one fluid conduit 5 to the reservoir 3 (or the reservoir 103). In some embodiments, the method includes connecting the first fluid conduit 5 to the breast cup 2 and the reservoir 3 (or the reservoir 103). In some embodiments, the method includes connecting the second fluid conduit 5 to the pressure source 9 (or the removable pumping unit 101) and the breast cup 2.
Releasable connections between the portable breast pump system 1 are advantageous for ease of cleaning.
The portable breast pump system 1 is advantageous in that the user may be able to breast pump a plurality of times following a one-time assembly. Prior to the first use, the user may secure the breast cup 2 to a breast and/or garment on their body. Then, in some embodiments, the user does not need to remove the breast cup 2 and/or garment between a plurality of breast pumping sessions, e.g., two, three, four, five, six, seven, eight, nine, or ten breast pumping sessions. The portable breast pump system 1 is further advantageous in that the user may be able to breast pump in a reclined position. As the portable breast pump system 1 may be used for an extended period of time, the user’s ability to place the wearable component on one time, yet still use the pump several times without removing the garment will allow for uninterrupted activity during at least one breast pumping session. A pre-programmed pumping schedule may initiate the portable breast pump system 1 at least once, e.g., two, three, four, five, six, seven, eight, nine, ten times, etc.
In some embodiments, the method includes pumping milk from the human breast to induce milk from a first breast pumping session by providing fluidic communication between the breast cup 2 and a first reservoir 3 (or a first reservoir 103) to allow milk from the first breast pumping session to flow into the first reservoir 3 (or the first reservoir 103); removing fluidic communication between the breast cup 2 and the first fluid reservoir 3 (or the first reservoir 103); establishing fluidic communication between the breast cup 2 and a second reservoir (or a second reservoir 103); pumping the human breast to induce milk from a second breast pumping session to flow from the nipple to the second reservoir via the breast cup 2. In some embodiments, the time between first and second pumping sessions is from about 30 minutes to about 240 minutes (e.g., about 30 minutes to about 45 minutes, about 30 minutes to about 60 minutes, about 30 minutes to about 90 minutes, about 30 minutes to about 120 minutes, about 30 minutes to about 180 minutes, about 45 minutes to about 60 minutes, about 45 minutes to about 90 minutes, about 45 minutes to about 120 minutes, about 60 minutes to about 90 minutes, about 60 minutes to about 120 minutes, about 50 minutes to about 180 minutes, about 60 minutes to about 210 minutes, about 90 minutes to about 120 minutes, about 90 minutes to about 180 minutes, about 90 minutes to about 210 minutes, about 90 minutes to about 240 minutes, about 120 minutes to about 180 minutes, about 120 minutes to about 210 minutes, about 120 minutes to about 240 minutes, about 180 minutes to about 210 minutes, about 180 minutes to about 240 minutes, about 210 minutes to about 240 minutes, about 30 minutes, about 45 minutes, about 60 minutes, about 85 minutes, about 90 minutes, about 105 minutes, about 120 minutes, about 135 minutes, about 150 minutes, about 165 minutes, about 180 minutes, about 195 minutes, about 210 minutes, about 225 minutes, or about 240 minutes).

The method may further include changing at least one of the first pressure or second pressure based on the temperature, weight, pressure, or flow measurement.
As noted above, the present disclosure provides methods of breast pumping while the user is in motion. Further, the present disclosure allows for methods to allow a mother or other care provider to carry out pumping in accordance with lifestyle preferences.
For example, speaking generally, if a new mother or other care provider wishes to resume activities requiring travel (e.g., to work), the possibility of not initiating or prematurely ending the breastfeeding period may increase. The present disclosure provides portable breast pump systems 1, which may be used while the user is in motion or moving between locations, such that the user may consistently pump milk while achieving other activities (e.g., travel to and from work) associated with their daily routine. The present disclosure further provides portable breast pump systems 1, which may be used while the user is working.
The present disclosure provides methods of breast pumping while resting, sleeping, or traveling.
For example, while attempting to sleep, the possibility of not initiating or prematurely ending the breastfeeding period may increase. It has been found that nearly 75% of sleep disruption in mothers is caused by breastfeeding. The present disclosure provides portable breast pump systems 1, which may be used during rest or sleep, thus allowing mothers to pump for a longer time post-birth while with reduced interruption of sleep.
In some embodiments, the breast cup 2 includes a wide portion 8 and a nipple tunnel 13, and the method includes contacting the human breast with the wide portion 8 of the breast cup 2. In some embodiments, the method includes positioning the nipple in the nipple tunnel 13 of the breast cup 2. In some embodiments, the method includes contacting two human breasts with the two breast cups 2.
In some embodiments, the method includes applying negative pressure to the pressure chamber 20 with the pressure source 9 (or the pressure source 107). The pressure around the nipple is reduced to below atmospheric pressure.
In some embodiments, the method includes deforming the diaphragm 18 away from the breast shield 19. In some embodiments, the method includes deforming the diaphragm 18 away from the inlet. In some embodiments, the method includes unsealing the inlet. Deformation of the diaphragm 18 away from the inlet allows milk to flow from the nipple to the milk chamber 21. In some embodiments, the method includes deforming the diaphragm 18 via negative pressure applied to the pressure chamber 20 to expand the milk chamber 21. In some embodiments, the method includes providing negative pressure to elongate the nipple. In some embodiments, the method includes drawing milk from the nipple. In some embodiments, the method includes drawing milk from the nipple tunnel 13 into the milk chamber 21. In some embodiments, the method includes drawing milk through the inlet.
In some embodiments, the method includes opening the control valve 10 and depressurizing the pressure chamber 20. In some embodiments, the method includes returning the diaphragm 18 to a nominal position. In some embodiments, the method includes closing the control valve 10.
In some embodiments, the method includes applying positive pressure to the pressure chamber 20 with the positive pressure source to deform the diaphragm and contract the milk chamber 21, and thereby force milk out of the milk chamber 21. In some embodiments, the method includes allowing the nipple to contract. In some embodiments, the method includes deforming the diaphragm 18 toward the breast shield 19. In some embodiments, the method includes allowing the diaphragm 18 to return to a nominal position. In some embodiments, the method includes sealing the inlet with the diaphragm 18. Deformation of the diaphragm 18 towards the breast shield 19 seals the inlet such that the nipple is allowed to contract. In some embodiments, the method includes sealing the orifices with diaphragm 18. In some embodiments, the method includes contracting the milk chamber 21. The contraction of the milk chamber acts to pump milk out of the breast cup 2.
In some embodiments, the method includes transporting milk from the milk chamber 21 to the reservoir 3 (or the reservoir 103). In some embodiments, the method includes transporting milk through the first fluid conduit 5. In some embodiments, the method includes transporting milk through the outlet 22. In some embodiments, the method includes transporting milk through the one directional valve 15. In some embodiments, the method includes applying pressure to a manifold (e.g., the manifold 108) with a pressure source 9 to transport milk to a reservoir 3 (or a reservoir 103). Thus, in some embodiments, the pressure source, or a second pressure source, can be in fluidic communication with the manifold (e.g., the manifold 108). In some embodiments, a positive pressure source is in fluidic communication with the manifold (e.g., the manifold 108) and transports milk to a reservoir 3 (or a reservoir 103). In some embodiments, the method includes applying a negative pressure source to the milk chamber 21 at the end of the pumping session. In this embodiment, the negative pressure transports any residual milk from the milk chamber 21 and fluid conduit 5 into the reservoir 3 (or the reservoir 103). In some embodiments, the negative pressure source is a peristaltic pump, e.g., on a first conduit or downstream component connected thereto. Positive pressure may also be introduced into the milk chamber 21, e.g., via a separate inlet, to aid in the transport of milk or cleaning. The clearing of milk from the fluid conduit 5 and/or milk chamber 21 may occur only once at the end of a breast pumping cycle.
The disclosure further provides methods of cleaning a portable breast pump system 1, including providing the portable breast pump system 1, providing a cleaning fluid to breast cup 2; and pumping the cleaning fluid from the breast cup 2 to the reservoir 3 (or the reservoir 103) or waste.
In some embodiments, the method includes providing a cleaning fluid to the portable breast pump system 1. In some embodiments, the method includes transporting a cleaning fluid from the breast cup 2 to a waste reservoir 3 (or a waste reservoir 103). In some embodiments, the cleaning fluid is water. In some embodiments, the method includes pumping milk from the human breast twice, in which there is at least 30 minutes between a first breast pumping session and a second breast pumping session. In some embodiments, the method includes pumping milk from the human breast 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 times. In some embodiments, the method includes pumping milk from the human breast a plurality of times (e.g., from 2 to 3 times, from 2 to 4 times, from 2 to 5 times, from 2 to 6 times, from 2 to 10 times, from 3 to 4 times, from 3 to 5 times, from 3 to 10 times, from 4 to 5 times, from 4 to 6 times, or from 5 to 10 times). In some embodiments, the method is used to pump breast milk about 8-10 times in 24 hours. Cleaning may occur once every 24 hours, e.g., after about 8-10 pumping sessions.
In some embodiments, a subject, including the human breast, is moving, reclining, resting, sleeping, or traveling.

EXAMPLES
Example 1: Exemplary Portable Breast Pump System
Example 1 presents an exemplary embodiment of a portable breast pump system 1 having the components and arrangement as shown in the schematic of FIG. 3.
An exemplary portable breast pump system 1 includes a pump unit 6 that houses a rechargeable battery as a power source 12 and a pressure source 9 that is a vacuum pump, which provides both negative and positive pressure. Three three-way solenoid valves allow the vacuum pump to switch between negative pressure, positive pressure, and atmosphere. One reservoir 3 fits into the pump unit 6, such that it is easily accessible, secured, and releasable. The pump unit 6 also includes a handle or a strap that allows for ease of carrying or wearability.
The pump unit 6 is in fluidic communication with the breast cups 2 via the first fluid conduit 5 and the second fluid conduit 5. The breast cups 2 are placed on the breasts of a user prior to breast pumping. Any breast cups may be used in conjunction with the pump unit 6 to provide an exemplary portable breast pump system 1. An exemplary breast cup 2 can be seen in FIG. 1, having a wide portion 8 and a nipple tunnel 13.
The portable breast pump system 1 includes controls that are operable by a user to select or modify at least one of the following: pumping program or mode, frequency of pumping cycle, maximum suction pressure achieved during a pumping cycle, latch suction pressure achieved during the pumping cycle, pumping force and pumping session time. In some instances, the controls may be accessible via an application on an external computer.
In the application, the user is able to set the pump programing including pumping length, cycle speed(s), vacuum level(s), and pump start time(s). The portable breast pump system 1 has two phases: a stimulation phase and an expression phase. The stimulation phase is typically characterized by a rapid initial stage, e.g., 100 cycles per minute, at a low to moderate vacuum strength. The initial rapid stage induces the letdown of milk and mimics the initial quick suckling motion of an infant. Once milk begins flowing, the system or the user typically switches the portable breast pump system 1 into the expression phase. Expression is typically characterized by slower cycles per minute, e.g., 38 cycles per minute, at moderate to high vacuum strength. The expression phase mimics an infant’s behavior at the breast with slower and deeper suckling. It is possible for the user to cycle between these two phases more than once per session. Once a user has completed the initial stimulation and expression phase, the user may switch back to stimulation mode to produce another let down of milk and then begin another expression cycle.
As utilized herein with respect to numerical ranges, the terms “approximately,” “about,” “substantially,” and similar terms generally mean ± 5% or 10% of the disclosed values, unless specified otherwise. As utilized herein with respect to structural features (e.g., to describe shape, size, orientation, direction, relative position, etc.), the terms “approximately,” “about,” “substantially,” and similar terms are meant to cover minor variations in structure that can result from, for example, the manufacturing or assembly process and are intended to have a broad meaning in harmony with the common and accepted usage by those of ordinary skill in the art to which the subject matter of this disclosure pertains. Accordingly, these terms should be interpreted as indicating that insubstantial or inconsequential modifications or alterations of the subject matter described and claimed are considered to be within the scope of the disclosure as recited in the appended claims.
It should be noted that the term “exemplary” and variations thereof, as used herein to describe various embodiments, are intended to indicate that such embodiments are possible examples, representations, or illustrations of possible embodiments (and such terms are not intended to connote that such embodiments are necessarily extraordinary or superlative examples).
References herein to the positions of elements (e.g., “top,” “bottom,” “above,” “below”) are merely used to describe the orientation of various elements in the FIGURES. It should be noted that the orientation of various elements can differ according to other exemplary embodiments, and that such variations are intended to be encompassed by the present disclosure.
Additionally, the terms “connected” or “coupled” and variations thereof, as used herein, means the joining of two members directly or indirectly to one another. Such joining may be stationary (e.g., permanent or fixed) or moveable (e.g., removable or releasable). Such joining may be achieved with the two members coupled directly to each other, with the two members coupled to each other using a separate intervening member and any additional intermediate members coupled with one another, or with the two members coupled to each other using an intervening member that is integrally formed as a single unitary body with one of the two members. If “coupled” or variations thereof are modified by an additional term (e.g., directly coupled), the generic definition of “coupled” provided above is modified by the plain language meaning of the additional term (e.g., “directly coupled” means the joining of two members without any separate intervening member), resulting in a narrower definition than the generic definition of “coupled” provided above. Such coupling may be mechanical, electrical, or fluidic. It is important to note that any element disclosed in one embodiment may be incorporated or utilized with any other embodiment disclosed herein. The systems and methods described herein may be embodied in other specific forms without departing from the characteristics thereof. The foregoing implementations are illustrative rather than limiting of the described devices and methods. The scope of the devices and methods described herein is thus indicated by the appended claims, and changes that come within the meaning and range of equivalency of the claims are embraced therein.
