Abstract

Dialysis liq. is degassed, just before entering an artificial kidney by passing the liq. through a vessel wherein the pressure is maintained below atmos. The degassing vessel has a top connection to a vacuum system, e.g. a receiver evacuated by a vacuum pump the connection being opened only when a predetermined volume of gas has accumulated and is automatically detected. Pref. the top section of the vessel is transparent and the gas accumulation detector comprises a photo-electric cell assembly sensing the level of liq. and actuating a solenoid valve to the vacuum system as the liq. level drops. Used for eliminating gases mostly oxygen and nitrogen, from dialysis liq. so that bubbles will not blind the dialysis membrane nor find their way into a patient's blood stream. Very simple, inexpensive yet quite positive means of degassing the liq. degassing takes place just upstream of the kidney with a minimum of possible air entrainment connections sepg. the two.
