Description

Breast pump is with inhaling milk pad and breast pump

Technical Field

The utility model relates to the technical field of articles for babies and children, in particular to a breast pad for a breast pump and the breast pump.

Background

At present, when a baby mother uses a breast pump to suck milk, a milk sucking pad in the breast pump is not in contact with the nipple of the baby mother, so that the difference in body feeling can be caused by the fact that the breast pump sucks the milk and the baby directly sucks the milk, and the baby mother does not feel the experience of sucking the milk of the baby. The milk is sucked mechanically by the milk sucking pump, the dynamic state of the sucking of the baby cannot be simulated, and the mother cannot secrete milk in time to successfully breast feed.

The patent of the reference document CN201921937992.5 discloses a breast pump pad of a breast pump, which comprises a first pad body in the shape of a horn, a second pad body arranged at the horn opening part of the first pad body and capable of being sleeved at the horn opening edge of the breast pump part, and a third pad body arranged at the horn receiving opening part of the first pad body and closing the horn receiving opening part of the first pad body, wherein a milk unloading opening is arranged on the third pad body, for simulating the sucking action of a baby, a thickening part is formed on one side of the inner wall of the first pad body and simulates the upper jaw of the baby, and the inner wall of the first pad body opposite to the thickening part simulates the lower jaw of the baby. When negative pressure is used for sucking milk, the milk sucking cavity expands, and when the negative pressure is lost, the milk sucking cavity recovers to be deformed to a natural state, and the process is similar to the process that a baby sucks breast milk, so that the effect of massaging and promoting lactation can be achieved. However, the thickened part of the inner wall of the first cushion body can press the breast of a mother during milk suction, and the user feels uncomfortable due to too large pressing force during suction.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a breast pad and a breast pump for a breast pump, wherein the narrowing section of the breast pad is not attached to the inner wall of the bell mouth, and the narrowing section can be gradually narrowed according to the internal pressure of a product to realize intermittent contact with the nipple of a baby mother, so that the baby mother feels like feeding the baby personally, and breast milk can be effectively stimulated to secrete.
