Abstract
A dental unit has a manifold module incorporating respective fluid-conducting conduits for the supply of water and air to dental instruments, each conduit leading to a respective self-sealing coupling member, said members forming a set located on one outer face of the manifold module for simultaneous releasable connection to a set of respective mating members on a manifold extension module. The manifold module may be corrected directly or via one or more manifold extension modules to one or more instrument control modules. Alternatively, the manifold extension modules and/or instrument control modules may be connected directly to a set of self-sealing coupling members located on a set of conduits supplying water and air.
Claims3
A service supply system for supplying at least air and water to a dental instrument comprising a supply unit having air and water sources and respective air and water outlets a first coupling module having at least two first conduits extending therethrough from respective air and water inlets to an air and a water outlet, self-sealing coupling members at each end of said air and water conduits normally sealing the inlet and outlet ends of said conduits, a control module having at least two control conduits extending therethrough having dental instrument control means operatively connected to said conduits, said control module having self-sealing mating coupling members at the respective inlet ends of said control conduits disposed for simultaneous releasable connection to said self-sealing coupling members of said first coupling module and operable when connected to said self-sealing coupling members to establish fluid communication between said conduits in said coupling module and said control conduits, said self-sealing coupling members automatically sealing the respective ends of said conduits when disconnected from their mating coupling members.
