DIAPHRAGM PUMP AND PUMP FOR DOUBLE-BREAST PUMPING |
摘要 |
A motorized pump which includes a flexible diaphragm (70) fitting within a rigid member (90), a motor drive mechanism (28) for driving a puller member (48) attached to the diaphragm away from the rigid member to create a space between the diaphragm and the rigid member and form a negative pressure region within that space, and an outlet communicating with the negative pressure region. In one embodiment, the pump provides a negative pressure in a single chamber which can be used to operate one or two breast shield assembles. In another embodiment, the pump is particularly adapted for double-pumping and provides two chambers which generate vacuum. |
