摘要：
A vacuum suspension system includes a pump system arranged to be in fluid communication with a prosthetic socket. The pump system includes a pump mechanism having a housing and a membrane situated on the housing such that a fluid chamber is defined between the membrane and the housing. The pump mechanism is movable between an original configuration in which the volume of the fluid chamber is zero or near-zero, and an expanded configuration in which the volume of the fluid chamber is increased.
