  • Publication number: 20230390491
    Abstract: A pressure detection system includes a body having an internal chamber with input and output ports and a flexible membrane fluidically sealed to an exposed opening of the chamber to prevent a fluid passing through the chamber from passing through the exposed opening. The membrane is configured to change shape responsive to an increase in pressure caused by the fluid within the chamber satisfying a predetermined threshold. In some implementations, the membrane includes or is part of an identification mechanism which moves outwards, away from the chamber, as the pressure increases to indicate the pressure increase. In some implementations, the identification mechanism includes markings on the surface of the membrane, and an image sensing device reads the markings, and provides an indication of a current pressure associated with the fluid in the chamber based on a variation in the markings from a default state.

  • Publication number: 20220080109
    Abstract: Bulbs for use with an IV set are described herein. A bulb includes a bulb body and a filter. The bulb body defines an inlet, an outlet, and a bulb volume in fluid communication with the inlet and the outlet. The filter is in fluid communication with the bulb volume. The filter captures particulate from a flow from the inlet to the outlet. The bulb body is deformable to compress the bulb volume and direct back flow from the bulb volume through the filter, agitating particulate captured in the filter, unclogging the filter and allowing for more flow.
