Blockable connector between sink drain and drainage stack.

Abstract

Toward the enabling of cleaning schedules involving one or more chemical treatments for the disinfection of healthcare room sink drainsets to avoid nosocomial infections arising from the vectoring of drain pathogenic bacteria, a blockable novel connector is presented to connect a sink drainset to an existing wall stub leading to a drainage stack behind the wall. Multiple chemical soaks for the drainset can be enabled through elaboration of the blocking plug temporarily inserted into the adapter. Two configurations, sideways and upward, are possible to connect the wallbend straight to the connector, the upward allowing for orthogonal connection between the straight and the receiving hub of the connector whatever the angle an existing wall stub has to the wall upon which the sink is hung. Additional blocking plug technology can be enabled.

What is claimed is: 
     
         1 . A ninety degree connector to connect a downstream straight tube of a sink drainset to a horizontal wall stub of pipe emanating from a healthcare room wall connected on the downstream end to a drainage stack leading to a sewer, and,
 a cleanout port on the connector sharing a centerline with the wall-stub and diametrically opposed to the downstream connection port of the connector, closed with either a cleanout cap or a blocking plug connected by one of a plurality of methods including but not limited to a sealing thread mate, where the blocking plug cylinder blocks egress of drainwater plug from the upstream port of the connector draining perpendicular to the centerline of the blocking plug.   
     
     
         2 . As in  claim 1 , excepting that a second ninety degree elbow is attached to the upstream port of the connector using a rotating compression basket nut and seal threading to an external thread on the upstream port of the connector such that the center line of the upstream port is vertical and parallel to the heathcare room wall. 
     
     
         3 . As in  claim 1  or  claim 2 , with a blocking plug configured to block or allow egress of drainwater when the plug is inserted into and connected to the cleanout port, by means of rotation of the plug in its inserted position. 
     
     
         4 . As in  claim 1  or  claim 2 , with a blocking plug configured with a plurality of antimicrobial technology including but not limited to pathogen diagnostic technology or pathogen kill technology.
