Description

Breast pump with function is collected to colostrum

Technical Field

The utility model belongs to the technical field of the breast pump, especially, relate to a breast pump with function is collected to colostrum.

Background

A breast pump refers to a tool for expressing breast milk accumulated in a breast. The infant formula milk powder is generally suitable for the situations that infants can not directly suck breast milk or mothers can not directly feed the milk, is widely applied to the mothers who are hospitalized with newborns and need to actively suck milk to provide colostrum for feeding and treatment, and is also suitable for the situations that modern professional women insist on work but breast feeding still occurs.

The breast pump can effectively help the lying-in woman dredge the mammary gland, start milk as early as possible, and ensure that the baby can timely eat the colostrum. Colostrum is the general term for the milk secreted by the parturient within 2-3 days after delivery. Colostrum contains not only fat lymphocytes taken up by phagocytosis, but also mammary cells, duct-derived cell fragments, nuclei, and the like. The colostrum has high contents of calcium phosphate, calcium chloride, etc., and thus has laxative effect and high colostrum calorie. The colostrum has a composition close to maternal plasma. The components of the colostrum are changed day by day, the contents of protein and inorganic substances are gradually reduced, the content of lactose is increased day by day, the ratio of casein is increased day by day, and the colostrum is changed into normal milk after 6-15 days.

Because the colostrum contains a large amount of immunoglobulin, it has effects of enhancing immunity of newborn, and preventing infection of newborn. Therefore, it is of great benefit to the newborn. However, the content of colostrum is generally low, the volume of the existing breast pump is large, most colostrum remains on the wall of the container after being sucked out, and colostrum collection is not facilitated. And when the newborn is fed for the first time, the sucking is not smooth, the milk is easy to cause milk waste, most of the milk is fed to the newborn through an injector in the feeding process, and after colostrum is collected, the colostrum is replaced into the injector from a collecting container, so that the breast milk pollution is easy to cause.

The breast cup of the existing breast pump is fixed in size, but the breast shapes of the lying-in women are different, so that the breast cup is not completely contacted with the breast of the lying-in woman, the sealing performance is poor, and the breast pumping effect is not thorough.
