Bionic sucking device of breast pump

Abstract

The invention provides a bionic sucking device of a breast pump which comprises a plastic outer casing of a sucking plate and a bell mouth silica inner casing which is covered on the inner surface of the plastic outer casing. The plastic outer casing is connected with a port of the sucking plate of a negative pressure generating device of the breast pump. Upper and lower lips simulating human mouth, upper and lower gums, mandible and maxilla are sequentially arranged on the bell mouth silica inner casing along the bell mouth inner concave direction. Buccinators simulating human face is arranged between the upper and lower gums and the port of the sucking plate. The upper and lower lips simulating human mouth, the upper and lower gums, the mandible and the maxilla are all arranged to be soft and salient. The bionic sucking device of the breast pump totally simulates the whole process actions of an infant sucking the breast. A massage head is arranged for massaging, and the sucking power for sucking the breast can be regulated. The bionic sucking device of the breast pump can promote the contraction of female uterus, strengthen the breast milk secreting ability, avoid breast diseases of mastitis and the like and achieve the aims of strengthening the body and keeping health.

Description

technical field [0001] The invention relates to a milk pumping device of a breast pump, in particular to a milk pumping device of a hand-pressed breast pump. Background technique [0002] At present, a kind of breast pump of being sold on the market. It is composed of a feeding bottle, a negative pressure generating cover threadedly connected with the feeding bottle, a breast suction plate connected with the negative pressure generating cover, and a sky cover on the negative pressure generating cover. The negative pressure generating cover is provided with a feeding bottle threaded interface, The threaded interface of the sucking pan, the negative pressure piston shell, the negative pressure piston covers the inner surface of the negative pressure piston shell, and is tightly connected with the negative pressure piston shell, the threaded interface of the breast sucking pan is exposed at the bottom of the negative pressure piston shell The negative pressure piston part and ...

It is composed of a feeding bottle, a negative pressure generating cover threadedly connected with the feeding bottle, a breast suction plate connected with the negative pressure generating cover, and a sky cover on the negative pressure generating cover. The negative pressure generating cover is provided with a feeding bottle threaded interface, The threaded interface of the sucking pan, the negative pressure piston shell, the negative pressure piston covers the inner surface of the negative pressure piston shell, and is tightly connected with the negative pressure piston shell, the threaded interface of the breast sucking pan is exposed at the bottom of the negative pressure piston shell The negative pressure piston part and the silicone valve located at the mouth of the feeding bottle together form a negative pressure space in the negative pressure generating cover, that is, when the negative pressure piston is lifted upwards, the silicone valve is closed, and the negative pressure space is enlarged to generate negative pressure. When the negative pressure piston resets downward, the negative pressure gradually disappears, the silicone valve opens, and the breast milk enters the feeding bottle; a lifting rod is arranged at the bottom of the negative pressure piston, and the lifting rod cooperates with one end of the pressing rod to pass One end of the pressure rod is pried up to drive the lifting rod up, and gradually lift the bottom part of the negative pressure piston, the other end of the pressure rod is exposed outside the negative pressure piston shell, and the fulcrum of the pressure rod is set on the negative pressure piston shell; The breast pump connected by the hood is composed of a plastic jacket and a bell-mouthed silicone inner sleeve. When breastfeeding, the bell-mouthed silicone inner sleeve is in close contact with the breast, but it cannot effectively stimulate the nipples and acupoints on the breast. It lacks healthy breasts and enhances secretion. function of milk

[0003] Chinese patent ZL200520010184.6 discloses a "bionic breast pump", which includes a breast pump, a milk tube connected to the breast plate, and a negative pressure generator. In the breast pan, the breast plate is connected to the milk tube There is a bionic nozzle connected with the sucking pan, the bionic nozzle is in the shape of a cylinder, and a cavity is opened along the circumference of the cylinder in the cylinder, and the cavity is connected with a rubber suction ball through a pipe; the bionic suction The bionic mouth of the breast pump is integrated with the breast pump. When in use, it is difficult for the breast and nipples to be naturally introduced into the breast pan and the bionic mouth, and the bionic mouth only has the ability to move up and down to compress and release the breast to express milk. The function of breast milk, that is, only simulates a part of the function of the human mouth, and cannot simultaneously produce sucking, opening and closing, and massage functions. The bionic breast pump also uses rubber suction balls, and the pipes connected to the rubber suction balls generate negative pressure to absorb milk. , making it a split structure, which increases the production cost of the product, and is large in size, takes up a lot of space, and is not convenient to use

[0004] To sum up, comparing the above two breast pumps, the former is an integrated structure, which is convenient to use, but lacks the function of imitating the human mouth; the latter is a split structure, which is relatively troublesome to use, and has the function of partially simulating the human mouth. Thereby, it is necessary to improve the structure of the above two
