Abstract
A mechanical fluid pressure modification valve, or “MFLP-valve”, is set forth. The MFLP-valve can be actuated upon movement of a movable pressure system member of a medical pressure system reaching a selected position. Additionally, the MFLP-valve can be actuated based on a pressure condition of the system. When the MFLP-valve unseals, a pressure differential between a pressure chamber and a volume outside of the chamber can be relieved. Disengagement of the movable pressure system member from the MFLP-valve can enable the MFLP-valve to re-seal. The MFLP-valve may include a flag that indicates the position of the movable pressure system member. The MFLP-valve may be provided in a diaphragm-type pressure source.
Claims10
A medical pressure system including a MFLP-valve comprising:
- a MFLP-valve configured to extend into a fluid flow section of the medical pressure system, the MFLP-valve including an operable cover and
- a post connected to the operable cover, the post configured to engage an aperture of the medical pressure system during operation of the medical pressure system;
- a movable pressure system member;
- and
- a diaphragm member having a rigid engagement member;
- wherein the operable cover via the post is configured to selectively open the aperture based on selective engagement with the movable pressure system member in the system, engagement occurring when the rigid engagement member is actuated by the movable pressure system member and contacts the post.
