Abstract:

A number of improvements relating to methods and apparatuses for kidney dialysis are disclosed. These include a method providing an apparatus for dialyzing to a consumer, with the apparatus including a controller for controlling a dialysate parameter, a delivery system for delivering the dialysate to a dialysate compartment of a dialyzer, and a user/machine interface having a touch screen to display an indicium corresponding to a parameter pertinent to operation of the apparatus for use in dialysis and to enable a user though touching the indicium to effect a change in the parameter. The method also includes providing supplies that are useable with the apparatus to the consumer.

US Classification:

417393, 417473, 251213

Abstract:

An air operated double diaphragm pump comprising an air valve mechanism. The air valve mechanism may comprise a single valve system that replaces the two valve system found in conventional air operated double diaphragm pumps. The position of the valve may be determined by the diaphragm motion of the pump up to a stall position. A spring-loaded mechanical actuation may complete the valve action from the stall position to the final or end of stroke position of the pump.
