ABSTRACT:
An automatic dispenser for spraying a liquid or flowable disinfectant to dermatologically treat hands or the like. The dispenser automatically senses the presence of a user's hands using an infrared sensing mechanism, and in response sprays a predetermined volume of volatile disinfectant onto the user's hands for a predetermined length of time via a control circuit. The control circuit supplies an electromagnet with power for the predetermined length of time to move a magnetic frame downward against an inverted bottle of disinfectant in the dispenser housing. The bottle contains a known quantity of disinfectant fluid and the dispensing operation dispenses a measured dose upon each actuation. A counter circuit then counts the doses dispensed and provides a warning signal when the bottle is empty or nearly empty of the flowable disinfectant. The dispenser has a nozzle with a conically shaped outlet which is in fluid communication with the inside of the bottle via a short tube which extends from the bottle opening and fits tightly to the nozzle. The dispenser operates automatically and avoids the need for the user to physically touch it. The user's hands thereby can be completely disinfected without the risk of recontamination from contact with the dispenser or with hand driers since the disinfectant is volatile and quickly evaporates.
