Abstract

The degassing system for use with a dialysis machine removes gases from liquids approximately at body temperature of 37 deg.C, and has a degassing chamber with a liquid inlet at the top and a liquid outlet at the bottom also a gas vent at the top. A vacuum is created in the chamber by a vacuum pump connected to the vent, and between the latter and the fluid outlet is a valve, maintaining liquid in the chamber at a predetermined level, typically between the fluid inlet and outlet. The valve can be in the form of a float (190) secured to the top part of the chamber by a swing arm (188). The arm carries a taper-ended rod (192) shutting off the liquid inlet (184).
