Breast pump capable of being used while user lies down without holding

Abstract

The invention relates to a breast pump capable of being used while a user lies down without holding, and belongs to the field of maternal and child appliances. The breast pump comprises a negative pressure source and a milk sucking device. Different from other milk sucking devices, the milk sucking device comprises a hemispheric cup and a bottom cover; a tapered breast holder fitting breasts of human bodies is arranged in the middle of the bottom cover; a central connection piece and a waterproof ring are embedded in the bottom cover; a connector of the central connection piece is connected with a one-way valve seat, the bottom cover, an air bag and a shell in an embedded manner, wherein the shell provides space needed by airbag deformation; the bottom cover and the central connection piece can be integrated. During use, the one-way valve seat is soaked in milk; the air bag is provided with a plurality of symmetrical grooves at least. The breast bump can be used when the user lies down without holding and is particularly suitable for weak puerperae.

Description

technical field [0001] The invention belongs to the field of electric appliances for mothers and infants, and in particular relates to a hand-free breast pump suitable for lying down. Background technique [0002] Breastfeeding is currently the most scientifically proven method of feeding babies, which is incomparable to formula milk powder and other complementary foods. A breast pump is a breastfeeding aid that helps a lactating woman collect milk to feed her baby. Generally speaking, a breast pump generally consists of a breast shield for sucking milk, a negative pressure generating device for providing suction, and a collection container for collecting milk. At present, although feeding bottles and milk bags can be used as collection containers for collecting milk, using a feeding bottle or a milk bag as a collection container requires the upper body of the user to stand upright to ensure that the milk in the feeding bottle or milk bag does not flow back.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there have been breast pumps with new structures, which basically have two structures: 1. The milk collection container and the synchronous suction device are separated, and the two are connected with a hose; the volume of the whole machine is relatively large , the installation before breastfeeding work is relatively cumbersome; 2. Although the milk collection container and the synchronous suction device are set together in the cup, they can only be used for breastfeeding when the upper body is upright
