Description

Auxiliary device for promoting breast feeding of newborn

Technical Field

The invention relates to the technical field of mother and infant products, in particular to an auxiliary device for promoting breast feeding of a newborn.

Background

Breastfeeding refers to the manner in which a mother's milk is used to feed an infant. Studies have shown that infants fed breast milk develop healthier and the effects include enhancing immunity and improving intelligence. Currently, the world health organization believes that breastfeeding may reduce the mortality rate of children, and that the health benefits it brings may extend into adulthood.

Many mothers now also put back on intense work during lactation and pumping breast milk and storing it for a short period of time is an important means to allow breastfeeding mothers to breastfeed newborns by third parties even when they are not.

In the prior art, a pump (e.g. a diaphragm pump) connected to the collection container is used to use a pulsating negative pressure. The negative pressure causes the teat to create a pumping action in a pulsating manner on the areola, where milk collects and is drawn through the teat due to the negative pressure.

However, milk secretion is a relatively complex process, which is influenced by both intrinsic regulation (lactation is promoted by hormones such as prolactin) and external stimulation (conditioned reflex of sucking nipple by baby), and specifically, the basic assumption that milk flows out of breast due to strong vacuum is not completely accurate, and the milk is not only inefficiently extracted only by strong vacuum, but also easily causes pain or even injury.

In addition, the secretion of breast milk of not everyone is optimistic, and some mothers have too little breast milk secretion, which is not enough to meet the requirement of feeding the newborn in one day, and the mixed feeding is needed at the moment. Mixed feeding refers to the feeding of infants mainly by breast feeding and supplemented by other milk substitutes, and the mixed feeding of breast milk and milk powder is a common method.

However, the method of feeding mixed breast milk and powdered milk is not easy to control the amount of breast milk and formulated powdered milk, and thus, the digestive disorder of the newborn is easily caused. In addition, some newborns also experience nipple confusion at some stage of mixed feeding and may therefore refuse to take a bottle or to take breast milk.

Therefore, there is a need to provide an auxiliary device for promoting breast feeding of a newborn, which solves the above problems of the background art.
