Abstract

425,272. Dental syringes. NIEDREE, G., 21, Rue Tournefort, Paris. July 9, 1934, Nos. 20078 and 20079. Convention dates, July 8, 1933 and Dec. 6, 1933. [Class 81 (ii)] The delivery tube 7 of a dental syringe is laterally offset from the axis of the cylinder 1 and a handle with depressions to fit the operator's fingers is provided at the base of the cylinder. For filling the syringe from an ampoule 16 the handle may have a suction passage 12 terminating in a nozzle 13 which projects into a conical depression 14 shaped to accommodate the neck of the ampoule. A 3-way cock 17 connects the cylinder with the suction or the delivery passage as required. Alternatively the filling means can be constructed as a separate fitting, Fig. 6, which can be screwed on to the end of the delivery tube 7 in place of the needle-holder 8, and is also applicable to syringes of known type.
