Accelerated bench-testing of medical devices

摘要

A biomedical tester includes a fluid-control container, shaped to define a fluid-control container port and a first interface surface defining fluid-control container apertures. A fluid controller is shaped to define a second interface surface defining controller ports. These elements and a motor are arranged to relative translation between the first and second interface surfaces; thereby effecting a time-varying overlap between subgroups of the system. Fixtures allow disposition therewithin of respective medical devices. Each of the fixtures includes one or more fixture first ports and fixture second ports. The fixture first ports are mounted in fluid Communication respective with the controller ports. A fluid pump includes first and second pump ports in fluid communication with the fixture second ports and the fluid-control container port, respectively.

1. Apparatus for fatigue testing one or more medical devices, the apparatus comprising:
a fluid control assembly, which comprises:
a fluid-control container, which is shaped so as to define a fluid-control container port and a first interface surface that is shaped so as to define one or more fluid-control container apertures;a fluid controller, which is shaped so as to define a second interface surface that is shaped so as to define one or more controller ports; anda motor,wherein the fluid-control container, the fluid controller, and the motor are arranged to effect relative translation between the first and second interface surfaces, thereby effecting a time-varying overlap between at least a subgroup of the fluid-control container apertures and at least a subgroup of the controller ports; one or more fixtures, configured to allow disposition therewithin of respective ones of the medical devices, each of which fixtures comprises one or more fixture first ports and one or more fixture second ports, which fixture first ports are mounted in fluid communication with respective ones of the controller ports; and a fluid pump, which comprises first and second pump ports, which are in fluid communication with the fixture second ports and the fluid-control container port, respectively.
