A system, method, and apparatus for preventing one with dirty hands from entering or exiting an area without first using a hand washing system. Typical uses would be in hospitals, where patients are endangered by health care workers who may propagate microorganisms and thus illness from patient to patient. The subject technology seeks to stop one from passing by having a barrier block passage. Overrides for bypass system on an emergency basis or when hands are otherwise necessarily occupied, such as in carrying a tray or other objects. Sensors detect presence of obstructions in the movement of the barrier. Further, the barrier may be broken should an emergency arise. Current implementation presumes that one's hands are dirty, and thus entry or exit is initially denied. Once hand washing has occurred, then entry or exit is allowed.
1. A method for dispensing a predetermined amount of sanitizing material in a hand hygiene encouragement protocol having a barrier to passage for one or more users requiring passage, the method comprising
detecting a count of the one or more users,
for each of the one or more users, dispensing the predetermined amount of sanitizing material through a dispense tube and then through a dispense port, the dispense port being deployed in the barrier,
allowing passage past the barrier for the one or more users according to the count,
detecting a passage count as each of the one or more users receives the sanitizing fluid and passes past the barrier,
and denying passage past the barrier upon a condition, said condition being after all of the one or more users have passed past the barrier or after a predetermined time.
2. The method of claim 1 wherein said dispensing of the sanitizing material comprises providing positive pressure to dispense the predetermined amount of the sanitizing material, the positive pressure being sufficient to move the predetermined amount of the sanitizing material past a trap conduit comprising a hump in the dispense tube, and providing negative pressure sufficient to stop dispensing of the predetermined amount of the sanitizing material.
