Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
173 words
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.
Claim 2
Dependent Claim
173 words
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.
Claim 3
Dependent Claim
127 words
A dental unit according to claim 1, wherein each coupling module comprises a central block member having housings for at least one set of coupling members in one outer face thereof adapted to mate with a corresponding set of female or male coupling elements in another coupling module, and housings for any valves or other controls for fluids passing through said module; an upper plate provided, in the surface thereof facing the central block, with a plurality of grooves; and a lower plate, provided in the surface thereof facing the central block with a plurality of grooves: the grooves in the said plates being connected with the housings in the central block via holes in the said central block to form the various conduits within the module.
Claim 4
Dependent Claim
113 words
The invention defined in claim 1 wherein said first coupling module is of block shaped configuration having a plurality of female self-sealing coupling members on one face of said module and a plurality of mating male self-sealing coupling members on the opposite face thereof aligned with said female coupling members and respectively connected thereto by second conduits communicating with the respective first conduit, whereby a plurality of said first coupling modules can be connected in series with each other, and a plurality of self-sealing coupling members on a face of said module intermediate said one and said opposite faces located to be connected to the mating self-sealing coupling members of said control module.
