Breast Pump

Abstract

A breast pump is disclosed. According to an aspect of the present invention, there is provided a breast pump comprising a contact housing comprising a protruding part configured to correspond to a mother's nipple and extend toward the front; a first space-defining member coupled to the protruding part to define a first inner space; a second space-defining member defining a second inner space linked with the first inner space; a storage housing comprising a coupling hole corresponding to the second inner space, the storage housing being coupled with the contact housing; a lid coupled to cover the second inner space through the coupling hole of the storage housing, the lid comprising an air passage; a flow separation membrane configured to divide and separate the second inner space into a first portion and a second portion, the first portion linked with the first inner space, the second portion linked with the air passage; and an attachable pump module on the lid to suck air of the second portion through the air passage, wherein the attachable pump module is integrally coupled with the lid to be attached to and detached from the coupling hole.

What is claimed is: 
     
         1 . A breast pump comprising:
 a contact housing comprising a protruding part configured to correspond to a mother's nipple and extend toward the front;   a first space-defining member coupled to the protruding part to define a first inner space;   a second space-defining member defining a second inner space linked with the first inner space;   a storage housing comprising a coupling hole corresponding to the second inner space, the storage housing being coupled with the contact housing;   a lid coupled to cover the second inner space through the coupling hole of the storage housing, the lid comprising an air passage;   a flow separation membrane configured to divide and separate the second inner space into a first portion and a second portion, the first portion linked with the first inner space, the second portion linked with the air passage; and   an attachable pump module on the lid to suck air of the second portion through the air passage,   wherein the attachable pump module is integrally coupled with the lid to be attached to and detached from the coupling hole.   
     
     
         2 . The breast pump of  claim 1 , wherein operating the attachable pump module allows the air between the lid and the flow separation membrane to be sucked in to the attachable pump module through the air passage, the flow separation membrane to move upward, a space between the flow separation membrane and the funnel connector to be expanded to form a vacuum pressure, and the vacuum pressure to be transferred to the first inner space to act as a force for extracting breast milk from a mother's breast. 
     
     
         3 . The breast pump of  claim 1 , further comprising
 a breast milk outlet tube linked with the first inner space; and   a silicone valve comprising one end coupled to an outlet of the breast milk outlet tube and a second pointed end comprising a cut line,   wherein breast milk is flowed out through the cut line and is filled into the storage housing.
