    摘要： A box for disposing of used injection needles comprising a case having an opening whereinto a tip portion of a syringe is inserted, a movable member, and a fixed member, both members being arranged in the case. A hub of an injection needle inserted through the opening of the case is firmly held by holding portions of movable member and fixed member due to elasticity of the hub itself. The rotation of the syringe causes the injection needle to be removed from the syringe, and the removed injection needle, which is not pulled out together with the syringe and remains in the holding portions due to holding effect of the holding portions, can be dropped into the case by the operation of a rod outside the case.

    摘要： A dental irrigation needle includes a hub engagable with a syringe and a cannula having one closed end and another end fitted to the hub, the cannula being formed of a freely bendable material such as annealed stainless steel. One or more nozzle orifices are formed in a lateral wall of the cannula adjacent the closed end so that a fluid from the syringe may be discharged through the nozzle orifices during the irrigation of a reamed root canal. The orifices are mutually axially and circumferentially spaced along the cannula and a marking may be provided on the hub to indicate a direction of each of the nozzle openings.
