Sucking type breast pump

Abstract

The invention relates to a sucking type breast pump which is used for extruding breast milk stored in breasts. The sucking type breast pump comprises a sucking unit and a control unit, wherein the sucking unit comprises a sucking cavity, a breathing cavity and a collecting bottle; and the sucking cavity is equipped with a lip gasbag and a tongue gasbag. When the breast pump works, the sucking cavity generates sucking effect under negative pressure, and the lip gasbag and the tongue gasbag generate sucking effect, so that the sucking actions of babies are simulated in a bionic mode, and therefore, user experience is more real without a pain feeling, and therefore, sucking is more sufficient, milk siltation is reduced, blockage due to milk reflux is avoided, breast diseases are effectively avoided, and milk re-secretion can be effectively promoted.

Description

technical field [0001] The invention relates to a sucking type breast pump for sucking milk from the breast of a lactating mother. Background technique [0002] The known breast pump is an essential child-rearing tool for lactating mothers, and is used to express the breast milk accumulated in the mammary glands. It is generally applicable to when the baby cannot directly suck breast milk, or when the mother has a problem with the breast, and even if she is working hard, but still wants to breastfeed. The main purpose of people using a breast pump is to suck out the milk in the breast, and suck as much as possible to stimulate the breast to secrete milk and prevent mastitis caused by milk stasis. [0003] WO2014 / 045159 (its Chinese patent application number is 2013800494433) discloses an automatic breast pump, which includes a breast pump body and an operating unit. The breast pump body includes a breast cup, a collector, and a breathing chamber. The operating unit includes...

AI Technical Summary

Problems solved by technology

[0005] 1. When the suction is normal, the milk output is small, the milk is sucked slowly, and the sucking is not empty, and it is easy to produce milk accumulation

[0006] 2. When the suction force is too large, it will cause the user's nipples to crack and cause unbearable pain

[0007] 3. In a working cycle, when the negative pressure starts, the nipple expands, the lactiferous sinus is filled with milk, and it is secreted through the lactiferous hole, when the suction is released, the nipple rebounds, and the milk inside the nipple and the lactiferous sinus flows back into the lactiferous duct This process can easily cause abnormal transitional epithelium at the junction between the lactiferous duct and the lactiferous antrum, and between the lactiferous duct and the breast lobules, resulting in blockage, thereby inducing acute mastitis
