  • Publication number: 20210285435
    Abstract: Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfectants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

  • Publication number: 20210093171
    Abstract: An endoscope has a pannable camera at the distal end of its insertion shaft, the pannable camera assembly being pivotable to provide a range of a field of view that can be equal to or greater than 180 degrees. A terminal light emitting element may be mounted to the camera assembly in order to illuminate the immediate field of view of the camera sensor regardless of the rotational position of the camera assembly. A fluid-carrying conduit of the insertion section may also be used to house functional components, including the camera assembly, actuation cables, a communications cable connected to the camera sensor, and/or a fiberoptic cable providing light to the light emitting element. A distal section of the endoscope handle may be rotatable relative to a proximal handheld section of the endo scope handle, a rotary encoder being provided to convert the rotational position of the insertion shaft relative to the handle into a signal for the purpose of image orientation correction by an electronic processor.
