[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention provides a breast pump airbag device that can alleviate nipple pain and has the following beneficial effects:

[0017] 1. Cover the breast shield on the outside of the breast and make the side end of the breast shield fit with the breast, then pull the first push-pull rod and the first piston outward to generate negative pressure inside the breast shield to simulate the sucking process of the baby, and then push and pull the second push-pull rod and the second piston. In the process of pushing and pulling the second piston, the rubber air bag is inflated and expanded and exhausted and contracted. In the process of the rubber air bag expansion and contraction, the baby's sucking process on the breast is simulated, so that the baby's sucking process can be completely simulated, and the milk can be sucked out, avoiding the milk being sucked out by simply using a suction, and avoiding the excessive elongation of the nipple due to a strong suction force, which causes the nipple to produce pain.

[0018] 2. When the first push-pull rod is pulled to move outward, the first push-pull rod is conveniently positioned and fixed by the positioning mechanism, so as to prevent the first piston from being sucked back by the internal negative pressure of the first round tube and the breast shield, so that the inside of the breast shield is kept within a certain pressure range, and at the same time, it is convenient for people to free their hands to perform other operations, thereby improving the practicality of its use.

[0019] 3. A milk tube and a connecting cap are connected at the bottom of the breast suction shield, and a feeding bottle is threadedly connected to the connecting cap. The milk after sucking flows into the inside of the feeding bottle through the breast suction shield, the milk tube and the connecting cap, and the milk is conveniently collected through the feeding bottle, so that more milk can be sucked at one time.

[0029] See also Figure 1-5 , a breast pump airbag device that can relieve nipple pain, comprises a breast shield 1, the upper side of the breast shield 1 is connected with a first circular tube 2, a first piston 3 is slidably arranged inside the first circular tube 2, a first push-pull rod 4 is fixedly connected to the side end of the first piston 3, the cross-section of the first push-pull rod 4 is a regular quadrilateral to prevent the first push-pull rod 4 from rotating, a first push-pull plate 5 is fixedly connected to the side end of the first push-pull rod 4, a positioning mechanism for positioning the first push-pull rod 4 is installed on the first circular tube 2, a rubber airbag 6 is fixedly connected to the upper and lower sides of the inner part of the breast shield 1, a second circular tube 7 is fixedly connected to the side end of the breast shield 1, a connecting seat 29 is fixedly connected between the first circular tube 2 and the second circular tube 7, the stability of the connection between the first circular tube 2 and the second circular tube 7 is improved, the second circular tube 7 is connected with the two rubber airbags 6 through a connecting tube 8, a second piston 9 is slidably arranged inside the second circular tube 7, a second push-pull rod 10 is installed on the second piston 9, and a second push-pull plate 11 is fixedly connected to the second push-pull rod 10.

[0030] Specifically, the breast shield 1 is covered on the outside of the breast, and the side end of the breast shield 1 is made to fit the breast, and then the first push-pull rod 4 and the first piston 3 are pulled outward to generate negative pressure inside the breast shield 1 to simulate the sucking process of the baby, and then the second push-pull rod 10 and the second piston 9 are pushed and pulled, and the rubber air bag 6 is inflated and expanded and exhausted and contracted during the process of pushing and pulling the second piston 9. The process of the rubber air bag 6 expanding and contracting simulates the process of the baby sucking the breast, so that the sucking process of the baby can be completely simulated, and the milk can be sucked out, avoiding the use of suction to suck out the milk liquid, and avoiding the excessive elongation of the nipple due to the strong suction force, which causes the nipple to feel painful. In the process of pulling the first push-pull rod 4 to move outward, the first push-pull rod 4 is conveniently positioned and fixed by the positioning mechanism, so as to avoid the internal negative pressure of the first round tube 2 and the breast shield 1 sucking the first piston 3 back, so that the inside of the breast shield 1 is kept within a certain pressure range, and at the same time, it is convenient for people to free their hands to perform other operations, thereby improving the practicality of its use.

[0031] See also Figure 5The second push-pull rod 10, the second piston 9 and the second push-pull plate 11 are all provided with vent holes 12. The second push-pull plate 11 is connected with a vent pipe 13 connected with the vent hole 12. The vent pipe 13 is installed with a valve 14 to facilitate adjusting the position of the second piston 9 inside the second circular tube 7.

[0032] Specifically, the valve 14 is opened, and the two rubber airbags 6 are connected to the outside, so that the second piston 9 can be driven to move inside the second circular tube 7 through the push-pull rod, and the second piston 9 can be adjusted to a suitable position inside the second circular tube 7. The valve 14 is closed, and in the process of pushing the second push-pull rod 10 and the second piston 9, the gas inside the second circular tube 7 is squeezed into the rubber airbag 6 to expand the rubber airbag 6. When the second push-pull rod 10 and the second piston 9 are pulled to move outward, the air inside the rubber airbag 6 is squeezed and sucked into the second circular tube 7, so that the rubber airbag 6 contracts.

[0033] See also Figure 2-4 The positioning mechanism includes a fixing seat 15, which is detachably connected to the first round tube 2. The fixing seat 15 is connected to the first round tube 2 by a second screw 30, which is convenient for disassembling the fixing seat 15. The fixing seat 15 is slidably matched with the first push-pull rod 4. A groove 16 is provided at the side end of the fixing seat 15, and a through groove 17 is provided at the side end of the groove 16. A slide plate 18 is slidably provided inside the groove 16. One end of the slide plate 18 close to the first push-pull rod 4 is fixedly connected to a fixing tooth 19, and the fixing tooth 19 is connected to the through groove 17. Sliding fit, the other end of the slide plate 18 is fixedly connected to the slide bar 20, and the side end of the slide bar 20 is fixedly connected to the handle 25, which is convenient for pulling the slide bar 20 to move. The outside of the slide bar 20 is slidingly provided with a fixed plate 21, and the fixed plate 21 is fixedly connected to the fixed seat 15 by a first screw 22. The outside of the slide bar 20 is sleeved with a compression spring 23, and the compression spring 23 is located between the fixed plate 21 and the slide plate 18. The end of the first push-pull rod 4 corresponding to the fixed tooth 19 is provided with a tooth groove 24 adapted to the fixed tooth 19.

[0034] Specifically, the slide plate 18 and the fixed teeth 19 are pushed to move by the compression spring 23, and the fixed teeth 19 are inserted into the tooth groove 24. In the process of pulling the first push-pull rod 4 to move outward, the slide plate 18 and the fixed teeth 19 move toward the inside of the through groove 17 and the groove 16 through the cooperation between the fixed teeth 19 and the inclined surface of the tooth groove 24, which is convenient for pulling the first push-pull rod 4 to move outward. When the first push-pull rod 4 is stopped, the cooperation between the fixed teeth 19 and the tooth groove 24 prevents the first push-pull rod 4 from moving toward the inside of the first round tube 2. The handle 25, the slide bar 20, the slide plate 18 and the fixed teeth 19 are pulled outward to separate the fixed teeth 19 from the tooth groove 24, which is convenient for moving the first push-pull rod 4 and the first piston 3 inside the first round tube 2.

[0035] See also Figure 1and Figure 2 The bottom end of the breast shield 1 is connected with a milk pipe 26 , and the bottom end of the milk pipe 26 is connected with a connecting cap 27 , and a milk bottle 28 is threadedly connected to the connecting cap 27 .

[0036] Specifically, a milk pipe 26 and a connecting cap 27 are connected at the bottom end of the breast shield 1, and a feeding bottle 28 is threadedly connected to the connecting cap 27. The milk after sucking flows into the interior of the feeding bottle 28 through the breast shield 1, the milk pipe 26 and the connecting cap 27, and the milk is collected by the feeding bottle 28, so that more milk can be sucked at one time.

[0037] In summary, when the overall equipment is in use:

[0038] The valve 14 is opened, and then the second push-pull rod 10 is pulled to move outward, and the second piston 9 is pulled to the side of the second round tube 7 away from the breast shield 1, and then the valve 14 is closed, and then the breast shield 1 is covered on the outside of the breast, and the side end of the breast shield 1 is made to fit the breast, and then the first push-pull rod 4 and the first piston 3 are pulled outward to generate negative pressure inside the breast shield 1. When a certain negative pressure is reached inside the breast shield 1, the first push-pull rod 4 and the first piston 3 are stopped, and the slide plate 18 and the fixed tooth 19 are pushed to move by the compression spring 23, and the fixed tooth 19 is inserted into the tooth groove 24. The first push-pull rod 4 and the first piston 3 are fixed by the cooperation of the fixed tooth 19 and the fixed groove. The suction force generated by this negative pressure is bearable by the parturient and there is no feeling of discomfort. In an appropriate range, due to the negative pressure generated inside the breast shield 1, the rubber airbag 6 expands within a certain range. Since the rubber airbag 6 generates a reverse pulling force during the expansion process, the expanded rubber airbag 6 does not squeeze the breast at this time, and the second piston 9 is located in the middle of the second round tube 7 at this time, and then by pushing and pulling the second push-pull rod 10 and the second piston 9, the rubber airbag 6 is inflated and expanded and exhausted and contracted during the process of pushing and pulling the second piston 9. The expansion and contraction process of the rubber airbag 6 simulates the process of a baby sucking the breast, thereby being able to completely simulate the process of a baby sucking, and being able to suck out milk. The sucked milk flows to the inside of the milk bottle 28 through the breast shield 1, the milk tube 26 and the connecting cap 27, and the milk is collected by the milk bottle 28.

[0039] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
