Zero net external displacement implantable pump and driver |
摘要 |
A zero net external displacement implantable pump for the transfer of accumulated body fluids, such as transfer of ascites fluid from the peritoneum to the vasculative system. The pump includes a pair of bellows type displacement chambers which are alternately compressed and expanded by action of a pivoted rocker member. The fluid to be transferred is drawn into the chambers on the expansion strokes and expelled on the compression strokes. The rocker member may be operated manually or power driven. Single action and double action pumps are disclosed.
