Abstract
Devices, systems, and methods for a valve assembly for a medical device. The valve has a cap, a stem which moves within a valve body, and a spring member between the cap and the valve body to move the valve within the body. The valve stem and/or spring member are made of a degradable material, which may be a metal. The degradable material has a higher degradation rate than conventional metal valve components to reduce the environmental impact of disposing of the valve.
Claims20
A valve assembly for a medical device, comprising:
- a valve body having an air inlet passage, an air outlet passage, a water inlet passage, and a water outlet passage;
- a valve cap positioned above the valve body;
- a spring member positioned between the valve cap and the valve body such that, when the valve cap is pushed downward relative to the valve body, the spring member applies upward force against the valve cap;
- and
- a valve stem connected to the valve cap and configured to translate within the valve body between an upper position and a lower position, the valve stem comprising a side wall and a central lumen extending from an air inlet in the side wall of the valve stem to the air hole in the valve cap, the valve stem made entirely of a degradable metal.
