Description

Technical Field

[0001] The invention relates to the technical field of breast pumps, in particular to a breast pump with a massage function. Background Art

[0002] A breast pump is an appliance used by lactating women to suck out milk. In the prior art, for example, a split three-way breast pump disclosed in Chinese patent application No. 202220834933.0 explains the specific structure and working principle of the breast pump.

[0003] During the process of mother's breast pumping, massaging the breast can promote blood circulation, accelerate metabolism, and promote tissue repair. For mothers, sucking milk during breast massage can relieve the pain of the mother's breasts and make the mother feel comfortable. In the prior art, such as a new type of massage breast pump disclosed in Chinese patent application No. 202121765348.1, it can massage the mother's breasts through the massage petal balloon in the silicone horn cover. As the air pressure inside the silicone horn cover changes, the massage petal balloon deforms to squeeze and massage the mother's breasts. However, this pressing method has disadvantages: it needs to ensure that the massage petals When the balloon is deformed, the mouth of the silicone horn cover is sealed against the mother's breast, because sealing can ensure that the space inside the silicone horn cover is closed, and the shape of the petal balloon can be changed through changes in air pressure. However, the massage caused by contact and compression with the mother's breast during the deformation of the petal balloon will easily cause the mouth of the silicone horn cover to no longer be sealed, so that the silicone horn cover and the mother's breast cannot form an enclosed space, and the petal balloon cannot be deformed normally through changes in air pressure in the enclosed space. In addition, the mouth of the silicone horn cover does not serve as a massage position for the breast, and will also produce a pressing effect, and the pressing at the mouth of the cover may cause discomfort to the mother's breast.

[0004] As for mechanical pressing, there is a breast massager disclosed in Chinese patent application No. 201610814587.9, which solves the problem that the mouth of the silicone horn cover must be sealed with the breast, avoiding meaningless pressure on the mother's breast by the mouth of the mask. However, since it has structures such as motors, some mothers dare not use it for fear of safety issues such as circuit short circuit or electromagnetic radiation. Summary of the invention

It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the protection scope of the present invention.

[0021] Embodiment 1:

[0022] Common breast pumps with massage functions in the prior art are all multi-point pressing type, but the pressing process is usually achieved by using a motor or an electromagnetic structure, which requires a connected circuit and has a complex structure. The breast massage cup provided in the background art is purely pneumatic, has a simple structure and does not connect the circuit, does not generate electromagnetic radiation or the risk of short circuit of the wire, but the massage effect achieved by it is completely different from the common massage effect of the prior art. Since it cannot accurately control the pressing position and will produce invalid pressing, its massage effect is poor. In order to solve the problem of poor massage effect, the breast pump with massage function provided in Example 1 of the present invention is as follows: Figures 1 to 4As shown, it includes a breast pump main unit 1, a breast pump tee 2, a milk bottle 3 and a massage shield 4; the breast pump tee 2 includes a milk inlet 21, a negative pressure port 22 and a milk outlet 23; the air inlet of the breast pump main unit 1 is connected with the negative pressure port 22; the milk bottle 3 is connected with the milk outlet 23; the massage shield 4 includes a base member 41, a flexible funnel-shaped shield body 42 and a pressing device 43; the base member 41 has a tubular connecting pipe 411 and a funnel 412 fixed on the connecting pipe 411, widened away from the connecting pipe 411 and used to accommodate the mother's breast; the other end of the connecting pipe 411 fixed with the funnel 412 is sealed and connected with the milk inlet 23; the pressing device 43 can press the shield body 42 from the outside; the connecting pipe 411 is a rigid connecting pipe 411; the funnel 412 is a rigid funnel 412; the shield body 42 is connected to the funnel 412; the cover body 42 extends toward the direction in which the large opening of the funnel 412 is opened; a plurality of vents 4111 are opened on the connecting pipe 411; the pressing device 43 includes an air pipe 431, a telescopic pipe 432 and a plurality of massage fingers 433; the air pipe 431 is connected to the vent 4111; one end of the telescopic pipe 432 is connected to the air pipe 431, and the other end is opened and closed; the massage fingers 433 are elastic; the massage fingers 433 are in the shape of arc sheets; the arc concave surface of the massage fingers 433 is arranged toward the outer wall of the cover body 42; when the massage fingers 433 bend toward the arc concave surface, they will press the outer wall of the cover body 42; the telescopic pipe 432 is arranged on the arc convex surface of the massage fingers 433; the telescopic pipe 432 is curved; the telescopic pipe 432 is fixed along the bending direction of the arc convex surface of the massage fingers 433.

[0023] When the breast pump with massage function provided by Embodiment 1 of the present invention is in use, the breast pump main unit 1 is operated to provide suction, so that negative pressure is generated in the closed negative pressure cavity connected to the negative pressure port 22 of the breast pump tee 2 (the specific structure inside the breast pump tee 2 is the prior art, the negative pressure port 22 and the breast pump tee 2 and a flexible membrane form a closed space, the milk inlet 21, the milk outlet 23, the breast pump tee 2 and the flexible membrane form another closed space, and the purpose of the flexible membrane is to prevent milk from entering the breast pump main unit from the negative pressure port 22), and the space in the closed negative pressure cavity is reduced, so that the negative pressure port 22 is isolated from the milk inlet 2 1. The flexible membrane of the nipple outlet 23 is deformed, so that the air pressure on the other side of the flexible membrane changes. The air pressure change is connected to the massage shield 4 through the nipple inlet 21; the funnel 412 of the massage shield 4 is close to the breast, and the inner wall of the funnel 412 is in contact with the breast to form a closed space, and the nipple is in this space (this space is composed of the breast, the inner wall of the funnel 412, and the inner wall of the connecting pipe 411. The only part of this space and the external ventilation is the connection between the connecting pipe 411 and the three-way connection of the breast pump). The cover body 42 is close to the breast, the inner wall of the funnel of the cover body 42 is close to the breast, and the connection between the connecting pipe 411 and the three-way connection of the breast pump is sucked. The nipple secretes breast milk, which enters from the funnel 412 and passes through the connecting pipe 411, flows into the three-way part of the breast pump and finally falls into the bottle; the connecting pipe 411 is provided with a vent hole 4111, and the vent hole 4111 is tightly connected with an air tube 431, and the air tube 431 is tightly connected with one end of the telescopic tube 432, and the other end of the telescopic tube 432 is closed. Therefore, when the air pressure in the closed space formed by the breast, the inner wall of the funnel 412 and the inner wall of the connecting pipe 411 changes, the air in the telescopic tube 432 will flow to the air tube 431 and finally to the vent hole 4111, because the telescopic tube 432 will be deformed after the gas is sucked inside. The massage finger 433, which is in contact with the telescopic tube 432 and whose convex curved surface is in the same curved direction as the telescopic tube 432, will also deform and bend to ensure that it is in contact with the telescopic tube 432. The massage finger 433 will tend to bend toward the concave curved surface of its curved sheet. In this embodiment, since the concave curved surface of the massage finger 433 faces the cover body 42, the curved sheet structure of the massage finger 433 will squeeze the outer wall of the cover body 42 when it is deformed. After being squeezed by the massage finger 433, the flexible cover body 42 will deform toward the inner wall of the cover body 42, thereby squeezing and massaging the breast in contact with the inner wall of the cover body 42.Compared with the prior art, in which the pneumatic massager uses pure negative pressure to deform the cover body, thereby using the cover body to press the breast, the present embodiment does not need to achieve complete sealing between the cover body 42 and the breast during the pressing process (the nipple is in the funnel 412, and the funnel 412 needs to be tightly attached to the breast, while the funnel 412 is rigid. When the air pressure inside it changes, the deformation degree of the funnel 412 is small, and the squeezing force between the funnel 412 and the mother's breast is small. It is the flexible cover body 42 part that has the massage effect on the mother's breast). Therefore, the ineffective compression of the breast by the edge of the cover body can be eliminated, and the deformation of the massage fingers 433 is used to press the outer wall of the flexible cover body 42, and the inner side of the cover body 42 will Correspondingly, the breast is pressed by the squeezing of the massage finger 433, which is closer to the effect of traditional mechanical pressing or electromagnetic pressing, and compared with mechanical pressing and electromagnetic pressing, the structure of this embodiment is simple; the massage finger 433 is arranged on the outside of the cover body 3, and by adjusting the position relationship between the massage finger 433 and the cover body 42, the position of the pressing caused by the deformation of the massage finger 433 can be made more accurate, so as to better massage the breast; the external air source can be a manual suction pump or an electric suction pump; although the electric suction pump needs to be connected to the circuit, it is pneumatically connected to the vicinity of the cover body 42 where it actually takes effect through the air pipe 431, which also avoids the risk of electromagnetic radiation or circuit short circuit, so it is safer. ;

[0024] The breast pump with massage function provided by the embodiment of the present invention solves the problem in the prior art that the massage breast pump will produce ineffective pressing and easy leakage, resulting in poor massage effect. The massage effect of the massage breast pump can be improved under the premise of ensuring safety (compared with the energized motor electromagnet approaching the mother's breast, the pneumatic and purely mechanical structure of this embodiment does not have the risk of funneling).

[0025] In order to specifically realize that the massage finger 23 can press the outer wall of the cover body 1, as a preferred solution, in this embodiment, the arc-shaped concave surface of the massage finger 433 has the same shape as the outer wall surface of the cover body 42; the arc-shaped concave surface of the massage finger 433 is tightly fixed to the outer wall of the cover body 42. The massage finger 433 is tightly attached to the outer wall of the cover body 41. When the massage finger 433 is deformed, the shape of the arc-shaped concave surface of the massage finger 433 will change, which will directly affect the outer wall of the cover body 42 that is tightly attached to the arc-shaped concave surface of the massage finger 433, thereby causing the outer wall of the cover body 42 to deform.

[0026] As a preferred solution, in this embodiment, the vent holes 4111 are arranged in a circular array on the pipe 411. The vent holes 4111 arranged in an equidistant circular array can, on the one hand, balance the suction generated by each air pipe 431, so that the extension and shortening degrees of the telescopic tubes 432 connected to each air pipe 431 are consistent; on the other hand, the vent holes 4111 in an equidistant circular array can facilitate the arrangement of the telescopic tubes 432, so that the telescopic tubes 432 can be evenly arranged on the outer wall of the mask body 42, so that the breasts can be evenly massaged by being close to the mask body 42.

[0027] As a preferred solution, in this embodiment, the telescopic tube 432 has a plurality of fixing parts 4321 fixed to the arcuate convex surface of the massage finger 433; the plurality of fixing parts 4321 are arranged along the bending direction of the arcuate convex surface of the massage finger 433; there is a gap between two adjacent fixing parts 4321; a connecting block 4322 is arranged at the fixing part 4321 on the telescopic tube 432; a plurality of fixing blocks 4331 are arranged at the arcuate convex surface of the massage finger 433; the connecting block 4322 is detachably connected to the fixing block 4331. The telescopic tube 432 has a connecting block 4321 at the fixing part 4321; a plurality of fixing blocks 4331 are arranged at the arcuate convex surface of the massage finger 433; the connecting block 4321 is detachably connected to the fixing block 4331. The distance between the fixed parts on the telescopic tube 432 will change as the telescopic tube 432 is extended and shortened. The change in the distance between the fixed parts will affect the shape of the massage fingers 433 fixed at the fixed points, causing the massage fingers 433 to also deform. The detachable fixation of the connecting block 4321 and the fixing block 4331 means that the connection method between the massage fingers 433 and the telescopic tube 432 can be adjusted. By changing the telescopic tube 432 at different telescopic lengths and fixing it to the connecting block 4331 on the massage fingers 433, when the telescopic tube 432 is extended and shortened, the massage fingers 433 can have different pressing effects due to different degrees of deformation.
