Automatic apparatus for cleaning dentistry hand-pieces or turbines

Claim 1

Automatic apparatus for cleaning one or more dental handpieces or turbines, comprising a housing having a compartment for receiving handpieces or turbines to be cleaned, said compartment having a hinged door, a plurality of dental motor noses projecting downwardly from a top of said compartment so as to receive dental handpieces or turbines to be cleaned, said noses being equipped with an internal shaft and driver, means for driving said shafts of said motor noses in rotation, fluid reservoirs in said housing comprising a water reservoir, a reservoir for a disinfectant fluid and a lubricant fluid reservoir, a source of air under pressure, supply lines connecting said source of air to said fluid reservoirs and connecting said reservoirs to said motor noses, solenoid valves positioned in said supply lines so as to control the transmission of the pressurized air to said reservoirs in predetermined timed sequence to propel the respective fluids through each of said supply lines and through said motor noses so that dental handpieces or turbines positioned thereon having internal shafts will be rotated by said shafts of said motor noses while fluids are passed through said handpieces, and further comprising a safety valve on said supply line of each of said motor noses to shut off said supply line of a motor nose when no handpiece is positioned thereon.
