Abstract
Abstract In accordance with the present invention, there is provided an asepsis dispenser apparatus for dispensing disinfectant solutions for cleansing and decontaminating the contaminated surfaces of dental, food and medical equipment, which equipment is connected to a water source by a water inlet line. The asepsis dispenser apparatus includes a housing having an interior compartment for holding in place first and second storage canisters, containing a first disinfectant composition and a second disinfectant composition. The asepsis dispenser apparatus further includes a two-way solenoid valve connected to both of the first and second storage canisters, and a three-way solenoid valve connected to the three-way solenoid valve, wherein the three-way solenoid valve is for controlling the water source supplied to the water inlet line which is connected to the dental, food or medical equipment. In addition, the asepsis dispenser apparatus includes a programmable timing controller device for opening and closing the solenoid valves in order to control the first and second storage canisters for supplying the first disinfectant composition or the second disinfectant composition to the contaminated surfaces; and a 9 volt battery power supply for supplying electrical power to both solenoid valves and to the programmable timing controller device.
