Abstract
Abstract A collection vessel (20) is connected with inlet fitting assemblies (12, 14) for receiving waste fluids. The collection vessel is connected by a valve (74) with a drain (70) for selectively draining collected fluids. A fluid inlet (84) that is connected with an exterior water source supplies water through interconnecting tubing to rinse waste residue from the collection vessel. The water flows through a housing member (200) that surrounds a tubular member (214) of the inlet assembly. The housing member is spaced by spacers (216) from the bottom surface (220) of a well (210) surrounding the tubular member such that trapped water is drained through a drain outlet (222). Powdered reagent (166, 168) is received in a cup (26) that is carried by a drawer (160) to a position above a fluid mixing reservoir (124). A mechanical actuator (172) lifts a mechanical assembly (174) which defines the reservoir, forcing a cutting blade (180) to pierce and cut open the cup. A pump (128) recirculates the water through the reservoir (124) to make a disinfectant fluid concentrate which is supplied to a venturi (120) to be selectively entrained in the rinse water.

Claim 1
Independent Claim
162 words
A self-disinfecting fitting assembly comprising: an inlet fitting including: a tubular member for frictionally receiving tubing along an outer surface thereof, the tubing member having an internal passage for receiving fluids from the tubing, an outer peripheral wall surrounding the tubular member, a base wall interconnecting the peripheral wall and the tubular member to define a well around the tubular member, a drain outlet extending from a region adjacent an intersection of the peripheral and base walls; an outer covering member including: a housing member having a peripheral edge which frictionally engages the inlet fitting peripheral wall in a fluid tight seal, a plurality of projections for holding the housing member offset from the inlet fitting base wall and defining a fluid passage in fluid communication with the drain outlet, the housing member defining an internal chamber which surrounds the tubular member in a spaced relationship thereto, and a fluid inlet into the housing member internal chamber for receiving a disinfectant fluid.
Claim 2
Dependent Claim
