Milk collecting device for simulating infant breast pumping method

The present invention relates to the field of baby products, and in particular to a milk collecting device simulating a baby sucking method.

Studies have shown that mothers' feelings have a great influence on the output of milk. Among them, positive feelings such as feeling very like baby, or thinking about the cuteness of baby, and believing that their milk is the best for babies, these can be Help the output of the milk to make the milk out. Other feelings such as touching or seeing a baby, or hearing a baby crying can also help with this reflection.

Therefore, the mother needs to be with her baby all the time, so that she can look at, touch and respond to him. This also helps her body prepare to start breastfeeding and help the milk out. If the mother is separated from the baby during the secondary feeding, the milk outflow will decrease.

At present, the milk collection device seen on the market is intermittently sucking on the nipple by a single negative pressure source. Although the milk can be sucked out, the milk secretion amount will be different after the mother uses it for a long time because it is completely different from the actual baby sucking. Gradually reduce, and in order to complete the pumping process as soon as possible, the suction is often adjusted too high, causing pain and discomfort during use.

U.S. Patent No. 6,706,012 B2 discloses a milk collection device of a dual air pressure source (sucking hood portion) which has the function of massaging the breast to stimulate the breast, but the function of the massage is only for the breast, and the nipple is deliberately avoided. There is also a gap between the feeling of milk and the feeling of actual baby sucking. In addition, it uses a single air pump as the source of air pressure, so that the dual air pressure source on the breastshield is quite interlocking, thus further limiting the variability of the breastshield control. It can't be close to simulate the feeling of actual baby sucking, and for the supply of dual air pressure source, the specification of single air pump must match one of the air pressure sources with large flow demand, which is wasteful to another air pressure source, resulting in waste. Its volume cannot be further reduced.

The characteristics of this creation are: its simple structure and high comfort during use. Under the control of the control circuit board, the cooperation of various components can achieve the feeling of actual sucking of the baby, thereby improving the amount of milk, and the effect is very good.

According to the baby breast pump research and ultrasonic photography, the baby's breast pumping action mainly relies on the change of the oral volume to generate negative pressure to suck out the breast milk. However, to accurately simulate the breast pumping action of the baby's mouth, such as the traditional milk collection device can not be achieved by a single negative pressure source, it must be combined with the simulation of the baby's oral peristalsis, so that the mother's nipple will feel like a baby sucking .

In order to achieve this goal, the creation simplifies the peristalsis of the baby's mouth into two major actions: 1. The mouth is closed. It is considered that the baby generates suction through the lower jaw to enlarge the oral space, so the intermittent opening through the mouth is intermittent. Suction. 2, swallowing, tongue like a wave of peristalsis to bring milk into the esophagus. The baby's complete breast pumping action is a continuous movement of mouth opening and swallowing. When the mouth is opened, a vacuum negative pressure is generated in the mouth. When the vacuum negative pressure reaches the maximum, the mouth is swallowed and swallowed. In order to generate the above-mentioned infant oral peristalsis and sucking action, one of the embodiments of the present invention is shown in FIG. 1; it includes a first negative pressure source 10, a second negative pressure source 20, a throttling pressure relief hole 12, and an electromagnetic pressure relief valve. 22. A first conduit 13, a second conduit 23, a breastshield 30, and a control circuit board 40. The first negative pressure source 10 is driven by the first negative pressure source driving motor 11 and connected to the breastshield 30 through the first pipe 13, and the first pipe 13 is provided with a flow pressure relief hole 12 communicating with the atmosphere, when the first negative When the pressure source 10 is closed, the negative pressure of the first pipe 13 and the breastshield 30 can pass through the throttling pressure relief hole 12 slowly disappears, the second negative pressure source 20 is driven by the second negative pressure source drive motor 21 and connected to the breastshield 30 by the second conduit 23, and an electromagnetic pressure relief valve 22 is disposed on the second conduit 23 to communicate with the atmosphere. When the pressure relief valve 22 is activated, the second conduit 23 communicates with the atmosphere, and the negative pressure of the second conduit 23 and the breastshield 30 can be quickly eliminated; the first negative pressure source driving motor 11, the second negative pressure source driving motor 21, and the electromagnetic The pressure relief valve 22 is controlled by a control circuit board 40.

As shown in FIG. 2 to FIG. 4, the breastshield 30 is composed of a cover body 31, an inner liner 32, and a milk collection container 33. The front end of the cover body 31 is a funnel-shaped breast receiving portion 311 for receiving the breast 01; 32 is a soft elastic body disposed between the inner side 312 of the breast receiving portion and the breast 01, and the inner substrate end 326 is provided with a sealing ring attached to the cover body 31, so that the outer side 321 of the inner liner forms a second gas with the inner side 312 of the breast receiving portion. The chamber 35 has a liner inner side 322 that is in contact with the breast 01 and forms a first air chamber 34. The cover body 31 is further provided with a first passage 313 and a second passage 314, wherein the first passage 313 connects the first air chamber 34 and the milk collection chamber. The container 33 is connected to the first negative pressure source 10 through the first conduit 13; the second passage 314 connects the second negative pressure source 20 to the second gas chamber 35 through the second conduit 23.

In order to increase the efficiency established by the negative pressure of the first negative pressure source 10, a one-way valve 37 may be selectively disposed between the first passage 313 and the milk collection container 33, so that the first negative pressure source 10 can be effectively reduced. The space of the negative pressure is established and does not affect the flow of milk into the milk collection container 33.

The inner liner 32 in direct contact with the breast 01 comprises three parts: a breast buffer section 323, a lip simulation section 324, and a tongue simulation section 325; the funnel-shaped portion of the front end of the inner liner 32 is a breast buffer section 323, which is provided with a buffer In the cylinder 3231, since the inner liner 32 is a soft elastic body, the breast buffer section 323 can increase the comfort when the breast 01 is in contact; in addition, the funnel-shaped root of the inner liner 32 is a lip simulation section 324, and the rear connection tongue simulation of the section Paragraph 325 As shown in FIG. 5, when the negative pressure of the second air chamber 35 is greater than the negative pressure of the first air chamber 34, the lip simulation section 324 approaches the breast receiving portion 311, thereby expanding the inner dimension of the lip simulation section 324 to simulate the oral cavity. The feeling of opening, as shown in FIG. 6, when the negative pressure of the first air chamber 34 is greater than the negative pressure of the second air chamber 35, the lip simulation section 324 returns to the original size to simulate the feeling when the oral cavity is closed; the tongue The simulation section 325 has an outwardly convex shape. When the negative pressure of the first air chamber 34 is greater than the negative pressure of the second air chamber 35, the tongue simulation section 325 is concentrated inwardly and attached to the nipple 011 due to the tongue simulation section. The range of 325 can completely cover the nipple 011. When concentrated inward, it will be attached to the side of the nipple 0111 and then wrapped to the front end of the nipple 0112, thereby generating the feeling of swallowing and swallowing.

In order to facilitate the installation and removal of the inner liner 32 and further help the airtightness of the first air chamber 34 and the second air chamber 35, a liner bracket 38 may be selectively added to fix the inner liner 32 and avoid installation and removal. Infected with milk when exposed to contact with milk. The complete breast pumping action is a continuous action of opening mouth and swallowing. Observing the baby's mouth ultrasound, the oral ultrasound can push the baby to open the mouth and the internal space of the mouth becomes larger, so that the vacuum inside the mouth produces a vacuum negative pressure when the vacuum negative pressure reaches the maximum. At the same time, the mouth is closed and swallowed, so the negative pressure control operation sequence of the first air chamber 34 and the second air chamber 35 is as follows: 1. The second air chamber 35 is under negative pressure (opening); 2. The first air chamber 34 is under negative pressure. Established (vacuum negative pressure generated in the oral cavity); 3. The first air chamber 34 and the second air chamber 35 simultaneously reach the maximum negative pressure (the vacuum negative pressure reaches the maximum); 4. The second air chamber 35 negative pressure disappears (close the mouth and 5. swallowing; 5, the first air chamber 34 negative pressure is reduced (the vacuum pressure in the oral cavity disappears); wherein the negative pressure of the second air chamber 35 is established earlier than the negative pressure of the first air chamber 34 Lie, but due to the simulated swallowing action, the negative pressure of the first air chamber 34 must be greater than the negative pressure of the second air chamber 35, so the establishment speed of the negative pressure of the first air chamber 34 needs to be greater than that of the second air chamber 35; The negative pressure of the second gas chamber 35 disappears earlier than the negative pressure of the first gas chamber 34, so the pressure relief rate of the second gas chamber 35 is faster than that of the first gas chamber 34. In other words, the suction flow rate of the first negative pressure source 10 must be greater than the second negative pressure source 20, but the pressure relief flow rate of the first negative pressure source 10 must be smaller than the second negative pressure source 20. Please refer to Figure 7 for the change of the negative pressure of each of the above-mentioned gas chambers with time. The change of the pressure difference can basically represent the action of the lip simulation section 324 and the tongue simulation section 325 of the inner liner 32. As shown in the time point of 51 in the figure, the positive pressure difference PdP is positive, and the negative pressure P2P of the second gas chamber 35 is larger than The negative pressure P1P of the first gas chamber 34 is the open mouth state; at the time point of 52 in the figure, the negative pressure value PdN is negative, and the negative pressure P2N of the second gas chamber 35 is smaller than the negative pressure P1N of the first gas chamber 34, This is the mouth and swallowed state.

In order to achieve the above control method, the first negative pressure source 10 and the second negative pressure source 20 must be vacuum pumps driven by different motors at different flow rates, and according to actual experiments, for the better effect, the first negative The flow rate of the pressure source 10 must be more than 5 times the flow rate of the second negative pressure source 20, and the ratio varies slightly depending on the spatial ratio of the first gas chamber 34 to the second gas chamber 35, and an effective sucking frequency is achieved ( 45~110Cycle/Min), the flow rate of the first negative pressure source 10 must be above 9L/Min. The following is an example of the control sequence of the suction frequency 50Cycle/Min, but the ratio of the time of each phase must be based on the first gas chamber 34 and the first The size and proportion of the two air chambers 35 are slightly adjusted to achieve the best effect; wherein all the phases of phase 1, phase 2, and phase 3 are added together as a total cycle time, and the total length of the cycle determines the length of the breast pump. The frequency of the phase 3 should account for 40%~60% of the total Cycle time, and the time of Phase 2 should be between 0.08~0.25 seconds.

However, the high-flow first negative pressure source 10 required for this embodiment has a large cost and volume, and two motors are required to drive the respective negative pressure sources, which are not ideal in terms of cost and product volume. Another preferred embodiment of the present creation is shown in FIG. The utility model comprises a first negative pressure source 10, a second negative pressure source 20, a negative pressure accumulator 14, an electromagnetic control valve 15, a throttling pressure relief hole 12, an electromagnetic pressure relief valve 22, a first pipeline 13, and a second pipeline. 23. The breastshield 30 and the control circuit board 40.

Wherein, the first negative pressure source 10 is driven by the driving motor 11A and connected to the negative pressure accumulator 14 to drive the motor 11A to operate for a full time (or nearly full time) to provide sufficient negative pressure in the negative pressure accumulator 14 The other end of the pressure storage container 14 is provided with an electromagnetic control valve 15 and connected to the breastshield 30 via the first pipe 13, and the first pipe 13 is provided with a pressure relief hole 12 communicating with the atmosphere. When the electromagnetic control valve 15 is activated, The negative pressure accumulator container 14 is connected to the first pipe to quickly establish the negative pressure of the first pipe 13 and the first air chamber 34 in the suction hood 30. When the electromagnetic control valve 15 is closed, the negative pressure accumulator container 14 and the first The conduit 13 is blocked, and the negative pressure of the first conduit 13 and the breastshield 30 can be slowly disappeared through the throttle pressure relief hole 12; the second negative pressure source 20 is also driven by the drive motor 11A and connected to the breastshield 30 through the second conduit 23. An electromagnetic pressure relief valve 22 is disposed on the second conduit 23 to communicate with the atmosphere. When the electromagnetic pressure relief valve 22 is activated, the first The second duct 23 is in communication with the atmosphere, and the negative pressure of the second duct 23 and the second air chamber 35 in the breastshield 30 can be quickly eliminated; the drive motor 11A, the electromagnetic control valve 15 and the electromagnetic pressure relief valve 22 are controlled by the control circuit board 40.

This embodiment can produce the same efficiency as the previous embodiment, but only needs to use a single motor to drive two vacuum pumps of the same specification as a negative pressure source, and the vacuum pump body can be a low flow vacuum pump (such as flow <3L/Min). Therefore, the volume can be greatly reduced and the cost can be reduced. Actual experiments have confirmed that the vacuum source can achieve the same effect by using a vacuum pump with a flow rate of 3 L/min, and the control sequence of the sucking frequency of 50 Cycle/Min is as follows:

In practice, two independent vacuum pumps can be used instead of a single-motor-driven double-pump vacuum pump, and a sub-optimal implementation, such as shown in FIG. 9, includes a first negative pressure source 10, a second negative pressure source 20, and a negative pressure storage container. 14. The electromagnetic control valve 15, the throttle pressure relief hole 12, the electromagnetic pressure relief valve 22, the first conduit 13, the second conduit 23, the breastshield 30, and the control circuit board 40, wherein the first negative pressure source 10 is first The negative pressure source driving motor 11 drives and connects the negative pressure accumulator container 14, and the first negative pressure source drives the motor 11 to operate for a full time (or nearly full time) to provide sufficient negative pressure and negative pressure in the negative pressure accumulator container 14. The other outlet of the pressure storage container 14 is provided with an electromagnetic control valve 15 and connected to the breastshield 30 via the first pipe 13, and the first pipe 13 is provided with a pressure relief hole 12 connected to the atmosphere. When the electromagnetic control valve 15 is activated, The negative pressure accumulator container 14 is connected to the first pipe 13 to quickly establish the first pipe 13 and The negative pressure of the first air chamber 34 in the breastshield 30, when the electromagnetic control valve 15 is closed, the negative pressure accumulator container 14 is blocked from the first pipe, and the first pipe 13 and the negative pressure of the first air chamber 34 in the breastshield 30 It can be slowly disappeared through the throttle pressure relief hole 12; the second negative pressure source 20 is driven by the second negative pressure source drive motor 21 and connected to the breastshield 30 through the second conduit 23, and an electromagnetic pressure relief valve is disposed on the second conduit 23. 22 is connected to the atmosphere. When the electromagnetic pressure relief valve 22 is activated, the second conduit 23 is connected to the atmosphere, and the negative pressure of the second conduit 23 and the second air chamber 35 in the breastshield 30 can be quickly eliminated; the first negative pressure source is driven. The motor 11, the second negative pressure source drive motor 21, and the electromagnetic control valve 15 have an electromagnetic pressure relief valve 22 controlled by a control circuit board 40.

This embodiment can produce the same efficiency as the other embodiments, but two low-flow vacuum pumps (such as flow rate <3L/Min) can be used as the negative pressure source, and the cost and volume can be lower than the first embodiment, although the cost and volume Slightly larger than the second embodiment, since the two negative pressure sources are driven by the individual motors, the first negative pressure source 10 and the second negative pressure source 20 are not interlocked, and the movement of each portion of the inner liner 32 can be controlled more flexibly and accurately. The actual experiment shows that both negative pressure sources can use the vacuum pump with a flow rate of 3L/Min to achieve the same effect. The control sequence of the suction frequency 50Cycle/Min is as follows:

Furthermore, as described above, since the two negative pressure sources are driven by the individual motors in this embodiment, the first negative pressure source 10 and the second negative pressure source 20 are not linked, and the inner liner 32 can be controlled more flexibly and accurately. Part of the action; therefore, if the accuracy of the control is to be further improved, a negative pressure sensor 60 may be added to the first pipe 13, and a negative pressure sensor 61 may be added to the second pipe 23, and the sensed The signal is fed back to the control circuit board 40, so that the control circuit board 40 can more accurately control the actions of the various parts of the lining 32 according to the feedback signal.
