  • TWO-WAY PRESSURE RELIEF VALVE FOR BLOOD RESERVOIR
    Publication number: 20210381612
    Abstract: A pressure relief valve for a reservoir has a housing body forming first and second subchambers in fluid communication. A first opening in a bottom surface of the housing body forms a first valve seat. At least one second opening in the bottom surface forms a second valve seat along an outer perimeter. A diaphragm member is biased against the second valve seat and is configured to deflect off of the second valve seat under a negative pressure. A sealing ball is gravitationally biased against the first valve seat and raises off the first valve seat in response to a positive pressure. A cover sheet on an upper surface of the housing body partially encloses the chamber and traps the sealing ball in the first subchamber. The cover sheet includes an aperture aligned with the second subchamber providing an ambient pressure port coupled to ambient atmosphere.
