Detachable handle for adjustable medical light or the like

A unitary, quick-release handle for use on dental, medical and similar lighting fixtures has a quick-release feature which permits the handle to be quickly and easily removed and then placed in an autoclave for purposes of sterilization.

The sterilizing pressure chamber of an autoclave is provided with two valve controlled vent paths. At the end of the sterilizing cycle of the autoclave a first vent path channels the sterilizing steam from the chamber into a condensing coil having an end which opens into a liquid reservoir. When the pressure within the chamber drops to a predetermined level, a second vent path, having a flow rate which is greater than the first path, opens and provides a channel for the rapid escape of the remainder of the steam from the chamber.

A console unit, particularly for use by a dental assistant, adapted to carry powered handpiece instruments and to provide storage space and working space utilized during the treating of a patient, is characterized by a mobile construction for easy access thereto. A main cabinet portion is provided for containing support apparatus for the powered handpiece instruments and for providing storage space. An upper work surface portion is movably carried by the main cabinet portion and has an upper generally flat working surface area thereon. A powered handpiece instrument storage compartment is secured to and suspended from one side of the upper work surface portion for movement therewith and for removably carrying a plurality of powered handpiece instruments and attached operating flexible hose for easy removal and use. Devices mount the upper work surface area for horizontal, forward and return movement for positioning of the upper work surface area and the handpiece instrument storage compartment in desired proximity to a user positioned in front of the console unit. Devices mount the upper work surface portion on the main cabinet portion for vertical upward and return movement of the upper work surface portion and the handpiece instrument storage compartment for positioning thereof at a desired elevation for easy access by the user.

Foot controller apparatus is characterized by providing for remote foot control by a minimum size foot pedal device of the flow of compressed air to an air driven dental handpiece or the like without the necessity of bulky air lines passing through or the incorporation of complicated electrical or mechanical mechanisms in the foot pedal device, as follows. An outwardly biased, depressible foot pedal device includes a diaphragm therein for forming an air sealed chamber which reduces in volume upon depression of the foot pedal device and conveys an air flow through an elongate tube to a diaphragm operated, air modulating, regulator valve positioned away from the foot pedal device and in the compressed air conduit leading to the dental handpiece for pneumatically operating the valve to control the flow of compressed air to the dental handpiece for driving same. The apparatus may also preferably include a diaphragm operated electrical switch mechanism electrically connected with electrically operated valves in chip air and coolant water conduits to the handpiece and with the foot pedal air tube for being pneumatically operated by the foot pedal device for controlling the flow of chip air and coolant water through the dental handpiece.
