Definitions
- the presently disclosed subject matter relates to a breast milk extraction kit comprising a breast milk pump and a pumping device.
- Breastfeeding is the best source of nutrition for a baby and provides health benefits to the nursing mother.
- a nursing mother needs to use a breast pump to collect milk.
- a variety of breast pumps are available, such as hand-operated pumps and electric pumps.
- the electric pumps may be battery and/or AC powered. Even though there are many breast pumps available, the need still exists for an improved user-friendly breast pump.
- the presently disclosed subject matter is related to a breast milk extraction kit including a breast milk pump, a pumping device and a cable configured to establish a connection therebetween.
- the aspects detailed below are related to various manners of operations of the kit and the breast milk pump.
- the breast milk pump is configured to be engaged with a breast and operated in order to extract milk therefrom.
- the below description of the aspects includes reference to the directions, which have been, for the purposes of this description, defined with respect to the body of a user when the user is standing in an upright position and is using the breast milk pump oriented in its upright orientation in which the milk collection container is positioned upright as well, and are intended to be understood accordingly.
- a direction along a height of the user is intended to be understood as a direction along the height of the user when the user is standing upright.
- Any reference to upper, lower, and sideways directions are intended to be understood with respect to the height of the user standing upright.
- a breast milk pump comprising:
- the position of the stimulating mechanism can at least partially define a size of an opening of the funnel configured to receive the breast, thus, by adjusting the position of the stimulating mechanism, a dimension of the opening of the funnel is controlled, thereby controlling a fit of the breast milk pump onto the breast during use of the breast milk pump.
- the position of the stimulating mechanism can be adjusted to adjust the size of the opening to fit the breast accordingly.
- the fit of the breast milk pump onto the breast can be adjusted to adapt for a sensitivity of the breast to any kind of stimulation that may vary from user to user. For instance, a user with a very sensitive breast would prefer comparatively lesser extent of stimulation and a user with lesser sensitive breasts would prefer a higher extent of stimulation for the milk to be extracted therefrom.
- the position of the stimulating mechanism also effects the extent of stimulation that would be experienced by the breast when the stimulating mechanism is operated. Furthermore, a user might want to adjust the fit of the funnel onto the breast based on a physical condition of the breast such as pain, swelling, soreness, etc.
- the stimulating mechanism can have any structure described herein with respect to some of the aspects or can be a structure known in the art as being configured to manipulate the flexible portion of the funnel to serve a general purpose of imitating tongue movements of a baby so as to stimulate the breast for extraction of milk therefrom.
- the position adjustment mechanism can be configured to move the stimulating mechanism between an initial position at which the stimulating mechanism causes the flexible portion to have a first shape at least prior to operation of the stimulating mechanism, and a final position at which the stimulating mechanism causes the flexible portion to have a second shape different from the first shape at least prior to operation of the stimulating mechanism.
- the stimulating mechanism causes a first tension in the flexible portion and at the final position, the stimulating mechanism causes a second tension, greater than the first tension, in the flexible portion.
- the first tension can be zero at least when the stimulating mechanism is not being operated.
- the initial position can be a lowermost position of the stimulating mechanism when the breast milk pump is held upright with a milk collection container being in an upright position as well, and the final position can be an uppermost position of the stimulating mechanism.
- the position adjustment mechanism can be configured to move the stimulating mechanism from the initial position to the final position thereof at least partially in a direction extending along a height of the user.
- the position adjustment mechanism can be configured to move the stimulating mechanism in an arcuate path.
- the position adjustment mechanism can be configured to move the stimulating mechanism majorly in a vertical path taken with respect to the breast milk pump being held upright with a milk collection container being in an upright position as well.
- the vertical movement of the stimulating mechanism results in more effective and quick adjustment of the grip of the breast milk pump with respect to the breast.
- the lever member can comprise a lever first portion articulated to the stimulating mechanism and a lever second portion, the lever member being configured to be pivoted in response to actuation of the lever second portion.
- the lever second portion can be actuated by the user directly holding the lever second portion.
- the position adjustment mechanism can comprise an actuator articulated to the lever second portion, the lever member being pivotable by the actuator.
- the breast milk pump can comprise a proximal portion configured to be positioned towards the breast, a distal portion configured to be positioned away from the breast, and a main axis extending therebetween, wherein the actuator is positioned distant from the stimulating mechanism at least in a direction along the main axis.
- the actuator being distant from the stimulating mechanism, which most generally would be under the breast, renders the use of the actuator easier and more effective.
- the actuator can be positioned at a location on the breast milk pump which is most convenient for the user to use while using the breast milk pump and is also visible to the user as to provide visual indications to the user indicating a state of the actuator and hence the position of the stimulating mechanism.
- the position adjustment mechanism can comprise two lever members, one on each side of the breast milk pump, and a respective actuator for each of the two lever members.
- the user can use any one of the actuators as per the convenience.
- the two lever members can be connected to each other such that actuating one of them causes the other one to follow the same path.
- the actuator is configured to move the lever second portion. The movement of the second lever portion can cause the lever first portion to pivot about the lever pivot axis.
- the lever member can comprise a lever first arm extending between the lever first portion and the lever pivot axis, and a lever second arm extending between the lever pivot axis and the lever second portion, and the lever first arm can be longer than the lever second arm.
- the relative length of the lever arms effects the extent of movement of the lever first portion relative to the movement of the lever second portion.
- the lever first arm being longer than the lever second arm causes the lever first portion to move comparatively more than the lever second portion is moved by the actuator. This results in requiring the user to do a lesser effort in adjusting the position of the stimulating mechanism.
- the position adjustment mechanism can be configured for a coarse adjustment of the position of the stimulating mechanism and for a fine adjustment of the position of the stimulating mechanism.
- the position adjustment mechanism can allow a user for a big movement of the stimulating mechanism by a particular extent of actuation of the actuator at the beginning of the adjustment and a relatively smaller movement of the stimulating mechanism by the same extent of actuation of the actuator as the adjustment proceeds. This allows the user to more accurately adjust the position of the stimulating mechanism. For instance, when the stimulating mechanism is far off from the desired position, a coarse adjustment can be done, and as the stimulating mechanism approaches the desired position and approaches the breast, a fine adjustment would be preferable by the user.
- the actuator can comprise a rotatable wheel.
- the position adjustment mechanism is configured to convert said rotation of the wheel into said movement of the stimulating mechanism articulated to the lever first portion.

- the spiral path can comprise an initial portion including the radially innermost end and a terminating portion including the radially outermost end, wherein a curvature of the path is greater at one of the initial and the terminating portion than a curvature of the path at other one of the initial and the terminating portion.
- the position adjustment mechanism can be configured for a coarse adjustment of the position of the stimulating mechanism, and when the follower is at other one of the initial and the final portions the position adjustment mechanism can be configured for a fine adjustment of the position of the stimulating mechanism.
- the position adjustment mechanism when the follower is at the initial portion, can be configured for a coarse adjustment of the position of the stimulating mechanism, and when the follower is at the final portion, the position adjustment mechanism can be configured for a fine adjustment of the position of the stimulating mechanism.
- the cam can be configured to lock the follower at one or more locations between the radially outermost end and the radially innermost end.
- the cam can be configured to prevent a movement of the follower by the lever member.
- the slope of the spiral path is so configured that the follower can be moved only by the rotation of the cam.
- the cam arrangement can comprise any other follower locking means to lock the follower at any location along the spiral path.
- the breast milk pump can further comprise a body and a stabilizing mechanism configured for controlling stabilizing of the lever member with respect to the body.
- the stabilizing mechanism can comprise a stabilizing biasing member configured for controlling an extent of the stabilizing of the lever member with respect to the body.
- the stabilizing biasing member can be a spring.
- the tension of the spring effects the extent of stabilizing of the lever member, i.e., more tense the spring would be, the more stabilized the lever member would be to the body.

- the controlling member can comprise a stabilizing cam configured to be rotated about an axle of the lever member to change the tension in the spring.
- the stabilizing cam can comprise a teeth member configured to lock the stabilizing cam in a plurality of positions, each position defining a corresponding tension in the spring.
- the stabilizing cam can be rotated by the user, which in turn controls the extent of stabilizing of the lever member.

Description
- The presently disclosed subject matter relates to a breast milk extraction kit comprising a breast milk pump and a pumping device.
- Breastfeeding is the best source of nutrition for a baby and provides health benefits to the nursing mother. Sometimes a nursing mother needs to use a breast pump to collect milk. A variety of breast pumps are available, such as hand-operated pumps and electric pumps. The electric pumps may be battery and/or AC powered. Even though there are many breast pumps available, the need still exists for an improved user-friendly breast pump.
- Generally, the presently disclosed subject matter is related to a breast milk extraction kit including a breast milk pump, a pumping device and a cable configured to establish a connection therebetween. The aspects detailed below are related to various manners of operations of the kit and the breast milk pump. The breast milk pump is configured to be engaged with a breast and operated in order to extract milk therefrom. The below description of the aspects includes reference to the directions, which have been, for the purposes of this description, defined with respect to the body of a user when the user is standing in an upright position and is using the breast milk pump oriented in its upright orientation in which the milk collection container is positioned upright as well, and are intended to be understood accordingly. For instance, a direction along a height of the user is intended to be understood as a direction along the height of the user when the user is standing upright. Any reference to upper, lower, and sideways directions are intended to be understood with respect to the height of the user standing upright.
- The various aspects described herein below are to be understood as implementable in any combinations, i.e., any or all of the features of one aspect can be used with any one of the other aspects.
- According to a first aspect of the presently disclosed subject matter there is provided a breast milk pump comprising:
- a milk extraction assembly comprising a funnel configured to engage a breast of a user, said funnel comprising a flexible portion having a flexible portion inner surface for facing the breast and an opposite flexible portion outer surface;
- a stimulating mechanism facing the flexible portion outer surface and configured to manipulate the flexible portion; and
- a position adjustment mechanism configured to adjust a position of the stimulating mechanism with respect to the funnel, said position adjustment mechanism comprising at least one lever member articulated to the stimulating mechanism, the lever member being pivotable about a lever pivot axis, to move the stimulating mechanism.
- The position of the stimulating mechanism can at least partially define a size of an opening of the funnel configured to receive the breast, thus, by adjusting the position of the stimulating mechanism, a dimension of the opening of the funnel is controlled, thereby controlling a fit of the breast milk pump onto the breast during use of the breast milk pump. For instance, for different sizes and shapes of breasts, the position of the stimulating mechanism can be adjusted to adjust the size of the opening to fit the breast accordingly. Further, the fit of the breast milk pump onto the breast can be adjusted to adapt for a sensitivity of the breast to any kind of stimulation that may vary from user to user. For instance, a user with a very sensitive breast would prefer comparatively lesser extent of stimulation and a user with lesser sensitive breasts would prefer a higher extent of stimulation for the milk to be extracted therefrom. The position of the stimulating mechanism also effects the extent of stimulation that would be experienced by the breast when the stimulating mechanism is operated. Furthermore, a user might want to adjust the fit of the funnel onto the breast based on a physical condition of the breast such as pain, swelling, soreness, etc.
- The stimulating mechanism can have any structure described herein with respect to some of the aspects or can be a structure known in the art as being configured to manipulate the flexible portion of the funnel to serve a general purpose of imitating tongue movements of a baby so as to stimulate the breast for extraction of milk therefrom.
- The position adjustment mechanism can be configured to move the stimulating mechanism between an initial position at which the stimulating mechanism causes the flexible portion to have a first shape at least prior to operation of the stimulating mechanism, and a final position at which the stimulating mechanism causes the flexible portion to have a second shape different from the first shape at least prior to operation of the stimulating mechanism. In some examples, at the initial position, the stimulating mechanism causes a first tension in the flexible portion and at the final position, the stimulating mechanism causes a second tension, greater than the first tension, in the flexible portion. The first tension can be zero at least when the stimulating mechanism is not being operated. The initial position can be a lowermost position of the stimulating mechanism when the breast milk pump is held upright with a milk collection container being in an upright position as well, and the final position can be an uppermost position of the stimulating mechanism.
- The position adjustment mechanism can be configured to move the stimulating mechanism from the initial position to the final position thereof at least partially in a direction extending along a height of the user.
- In some examples, the position adjustment mechanism can be configured to move the stimulating mechanism in an arcuate path.
- In some examples, the position adjustment mechanism can be configured to move the stimulating mechanism majorly in a vertical path taken with respect to the breast milk pump being held upright with a milk collection container being in an upright position as well. The vertical movement of the stimulating mechanism results in more effective and quick adjustment of the grip of the breast milk pump with respect to the breast.
- The lever member can comprise a lever first portion articulated to the stimulating mechanism and a lever second portion, the lever member being configured to be pivoted in response to actuation of the lever second portion. In some examples, the lever second portion can be actuated by the user directly holding the lever second portion.
- The position adjustment mechanism can comprise an actuator articulated to the lever second portion, the lever member being pivotable by the actuator.
- The breast milk pump can comprise a proximal portion configured to be positioned towards the breast, a distal portion configured to be positioned away from the breast, and a main axis extending therebetween, wherein the actuator is positioned distant from the stimulating mechanism at least in a direction along the main axis. The actuator being distant from the stimulating mechanism, which most generally would be under the breast, renders the use of the actuator easier and more effective. Thus, the actuator can be positioned at a location on the breast milk pump which is most convenient for the user to use while using the breast milk pump and is also visible to the user as to provide visual indications to the user indicating a state of the actuator and hence the position of the stimulating mechanism. For instance, the user can hold the breast milk pump by a first hand and using the second hand for conveniently using the actuator without intervening the area of the funnel. In some examples, the position adjustment mechanism can comprise two lever members, one on each side of the breast milk pump, and a respective actuator for each of the two lever members. The user can use any one of the actuators as per the convenience. The two lever members can be connected to each other such that actuating one of them causes the other one to follow the same path. The actuator is configured to move the lever second portion. The movement of the second lever portion can cause the lever first portion to pivot about the lever pivot axis.
- In some examples, the lever member can comprise a lever first arm extending between the lever first portion and the lever pivot axis, and a lever second arm extending between the lever pivot axis and the lever second portion, and the lever first arm can be longer than the lever second arm. The relative length of the lever arms effects the extent of movement of the lever first portion relative to the movement of the lever second portion. The lever first arm being longer than the lever second arm causes the lever first portion to move comparatively more than the lever second portion is moved by the actuator. This results in requiring the user to do a lesser effort in adjusting the position of the stimulating mechanism.
- The position adjustment mechanism can be configured for a coarse adjustment of the position of the stimulating mechanism and for a fine adjustment of the position of the stimulating mechanism. The position adjustment mechanism can allow a user for a big movement of the stimulating mechanism by a particular extent of actuation of the actuator at the beginning of the adjustment and a relatively smaller movement of the stimulating mechanism by the same extent of actuation of the actuator as the adjustment proceeds. This allows the user to more accurately adjust the position of the stimulating mechanism. For instance, when the stimulating mechanism is far off from the desired position, a coarse adjustment can be done, and as the stimulating mechanism approaches the desired position and approaches the breast, a fine adjustment would be preferable by the user.
- The actuator can comprise a rotatable wheel.

The actuator can comprise a cam and the second lever portion being articulated to the cam via a follower. The follower can be a separate member or can be a part of the lever second portion. The cam can comprise a spiral path extending between a radially outermost end and a radially innermost end thereof. The follower can be biased to retain the spiral path when the cam is rotated, thereby following the variation in radius of the spiral path. When the follower is at one of the radially innermost end and the radially outermost end, the stimulating mechanism is at the initial position, and when the follower is at other one of the radially innermost end and the radially outermost end, the stimulating mechanism is at the final position.

Thus, the vacuum chamber needs to be washed. However, if the vacuum chamber is not detachable, especially in the breast milk pumps comprising electrically operable components (e.g. motor, sensors, display units, controllers, connectors, etc.), washing the same is difficult. Thus, the vacuum chamber being detachable allows a user to wash the vacuum chamber without risking the electrically operable components.

The vacuum chamber can comprise a chamber locking portion and the cap can comprise a cap locking portion, wherein the at least one locking means comprises a snap connector configured to receive the chamber locking portion and cap locking portion. The snap connector can comprise a first snapping portion configured to engage with and to lock the chamber locking portion, and a second snapping portion configured to engage with and to lock the cap locking portion.
