摘要：
A fatigue testing system (100) provides simultaneouscycle testing for a plurality of prosthetic devices under simulatedphysiological loading conditions. A plurality of sample holders (129)containing test samples (130) of prosthetic devices is positionedbe-tween a distribution chamber (126) and a return fluid chamber (136)to form an integrated test chamber (106). A reciprocating linear drivemotor (105) operates a rolling bellows diaphragm (115) to cyclicallypressurize fluid within the test chamber (106) and drive thepressur-ized fluid through the prosthetic devices (130) being tested. The testchamber (106) defines a return flow conduit (124) in fluidcommuni-cation with each of the sample holders (129), the return fluid chamber(136), and the distribution chamber (126). Compliance chambers(135) and throttle valves (132) associated with each of the sampleholders (129) regulate the pressure gradient and back pressure acrossthe prosthetic devices (130) being tested.
