合した容器４内に流れ込み貯留される。When milking using wooden stirrups, the wrapper 2 of the sucking part 1 is placed against the breast, and a switch (not shown) is operated to drive the electric motor of the electric negative pressure source 11 to drive the diaphragm suction pump. Then, the air inside the wrapper 2 flows through the communication path 1.
0 and the inside of the wrapper 2 becomes a negative pressure state, thereby sucking the breast and causing the milk to flow out. The spilled breast milk flows from the wrapper 2 through the lid 3 into the container 4 screwed onto the lid 3 and is stored therein.

The cam member 24 of the pressure adjustment means 20 provided on the wrapper 2
Rotate. As a result, the valve sleeve 22 moves back and forth in the axial direction, the biasing force of the valve body 23 against the valve sleeve 22 changes, and the negative pressure within the wrapper 2 is set to a desired level. When the negative pressure inside the wrapper 2 becomes higher than a predetermined level, the valve body 23 is pulled upward in FIG. It flows into the wrapper 2 through the communication hole 21b and the through hole 2b, reducing the internal negative pressure.

整を行なうことができる。Therefore, the pressure within the wrapper 2 can be maintained at a negative pressure level that does not cause the breast to feel pain. Moreover, when the negative pressure increases, the valve body 23 is separated every time the predetermined pressure is exceeded, so the pressure adjustment is realized in a pulsating manner, giving the breast a pleasant stimulation as if it were sucked by an infant. This allows for smoother flow of breast milk. Furthermore, the above-mentioned pressure adjustment is performed by a force acting on the valve body 23 due to a pressure difference between the pressure inside the wrapper 2 and the outside air pressure,
Since the valve body 23 is operated with a slight force difference between the biasing force of the valve spring 26 and the urging force of the valve spring 26, precise fine adjustment can be performed.

きる。An example of the procedure for assembling this breast pump is to screw the lid 3 of the sucking part 1 onto the container 4, fit the connecting member 5 into the joint 6 of the lid 3, and connect the electric negative Connection part 13 of pressure source 11
is inserted into the connection port 13 of the connecting member 5. Thereby, the electric negative pressure source 11 and the inside of the wrapper 2 of the sucking section 1 are communicated via the communication path IO. Therefore, with this breast pump, disassembly work and washing work can be easily performed.
