Patient employed digital operated syringe device for irrigating periodontal pockets and other soft tissue spaces

摘要

A periodontal lavage syringe is provided for self home use by an unskilled patient in the treatment of periodontal disease by irrigation of periodontal pockets or other soft tissue spaces. The syringe may have a single liquid retaining barrel or preferably multiple barrels, each of which contains a dispensible plunger and each of which is filled with a different treatment fluid. The bores communicate with a single liquid outlet to which is attached a flexible needle or tube terminating in a nozzle which is preferably elastomeric. The nozzle is conical in shape, having a pointed tip which enables easy insertion of the nozzle into the periodontal pocket, and tapered walls, the increasing diameter of which limits the depth of insertion of the nozzle within the pocket. Ratchet devices mounted on the syringe body are coupled to the plungers and are manually operable by the fingers of the user's hand holding the syringe to feed the different liquids successively and alternately into the periodontal pocket in equal pre-selected incremental doses.
