US Patent 9417110 Accelerated bench-testing of medical devices

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.
