Dental control unit

Utility box for housing and supporting dental equipment

The seal (10) comprises a one-piece molded cylindrical body having an open end (12), a closed end (16) , and a cylindrical side wall (14) . Outwardly projecting sealing ridges (26 and 18) are formed on the wall portion. Seal 10 is inserted into a bore (38) in a control panel (40) such that the sealing ridges contact the bore to seal out moisture, chemicals and other contaminants, and to retain the seal in the bore against upwardly directed pressure.

Seal for push-button switches

Apparatus useful for rotatably securing a dental instrument holder to a rod and enabling a convenient manual adjustment of the angular position of the instrument holder.

Rotation adjustment for dental instrument holder

The bracket (12) is bolted loosely to the attachment arm (14) of a dental chair to establish a preliminary orientation of the bracket relative to the attachment arm. The bracket is then levelled with adjustment screws (40) which bear against a surface on the attachment arm to establish a level orientation. The bolt fastening the bracket to the attachment arm is then tightened to fix the level orientation.

Mounting mechanism

The frame includes a support plate that has openings fitted with sleeved hubs. The openings and hubs are configured to support dental equipment components that are carried by posts. The frame is constructed so that a given component is readily mounted to any selected one of the openings, thereby providing a variety of user-specified options in equipment arrangement with a single frame configuration.

Holder for a dental instrument

A dental instrument holder is combined with a compact valve assembly that is operable for conveying signals to a control system whenever and instrument is removed from or returned to the holder.

Dental syringe

An extruded conduit structure for conveying several different fluids is provided comprising a cluster of at least three tubes connected by webs extending between adjacent pairs, the tubes and webs being formed by simultaneous extrusion of a suitable plastic through a suitable die. The outer surface of each of the webs is convexly curved in an arc that is substantially tangential with the outer surfaces of the adjacent pair of tubes. The inner surface of each of the webs is flat relative to the outer surface and forms a cord of such arc whereby each of the webs will be of minimum thickness along each of its junctures with the adjacent webs. This construction substantially eliminates any concave surfaces on the exterior of the conduit within which foreign matter may collect and, because of the thinner wall sections at the juncture of the webs with the adjacent tubes, the webs can be easily stripped along the tubes to expose the tube ends for connection to the appartus, such as a dental handpiece to which they are to be connected.

Flexible conduit structure for dental appliances

An in-line quick connect multiple port fluid coupler is disclosed. The coupler has two identical coupling units. Each coupling unit has a body and an integral tongue. The tongue has a face which is perpendicular to the longitudinal axis of the coupling unit. Fluid passages interconnect the body and the face of the tongue. Each coupling unit mates in a face-to-face relationship with the other coupling unit. Guide pins and seals are used to provide a fluid tight passage between the fluid passages and each opposing face. A sleeve circumscribes the mated coupling units to ensure a secure assembly.
