Abstract

A surgical scrub sink includes a faucet mounted over a tub with an electronically operated on/off mechanism for controlling the flow of water from the faucet into the tub. A short focus sensor is mounted at the tub and directs a beam toward the front of the tub at the height of the user'"'"'s legs for detecting the presence and absence of a user in the immediate vicinity of the tub. The sensor is operatively connected to the on/off mechanism so as to turn on the faucet when the presence of the user is detected and turn off the faucet when the absence of a user is detected.

Claims

1. A surgical scrub sink comprising a tub mounted to a support wall and above a floor wherein said tub includes a drain hole and a drain tube connected to said drain hole, a faucet mounted over and disposed toward said tub, an electronically operated on/off mechanism including a solenoid controlled electronic mixing valve for controlling the flow of water from said faucet into said tub, a narrow beam, short focus sensor mounted on a support arm below the tub attached to the tub drain tube wherein said support arm is of elongated shape including a main bracket, an extender bracket slidably mounted to said main bracket and lockable in position for varying the effective length of said arm, and said sensor being mounted to said extender bracket, and wherein said support arm also contains adjustment screws disposed against said wall, said sensor being mounted at an elevation of from about six inches to about thirty inches above said floor and directing a beam toward the front of the tub, said sensor having a focal length of about 2-6 inches for detecting the presence and absence of a user in the immediate vicinity of said tub, and said sensor being operatively connected to said on/off mechanism for turning on said faucet when the presence of a user is detected and for tuning off said faucet when the absence of a user is detected.

2. A surgical scrub sink comprising a tub mounted on a wall wherein said tub includes a drain hole and a drain tube connected to said drain hole, a faucet mounted over and disposed toward said tub, an electronically operated on/off mechanism including a solenoid controlled electronic mixing valve for controlling the flow of water from said faucet into said tub, a narrow beam, short focus sensor mounted on a support arm attached to said tub drain tube below said tub, said support arm having adjustment screws at one end thereof for placement against said wall, said sensor being attached to the support arm near the front of the tub at an elevation of from about six inches to about thirty inches above said floor and directing a beam toward the front of the tub, said sensor having a focal length of about 2-6 inches for detecting the presence and absence of a user in the immediate vicinity of said tub, and said sensor being operatively connected to said on/off mechanism to turn on said faucet when the presence of a user is detected and for turning off said faucet when the absence of a user is detected.
