THE DENTAL SYRINGE WITH ASSISTANT PRESSURE PART FOR LOCAL ANESTHESIA

摘要

The present design relates to the topical anesthetic equipped with additional auxiliary pressure syringe. And the secondary pressure added local anesthetic syringe provided of the subject innovation, the incision portion is formed on one side of the anesthetic ampoule to be inserted, and the body that is, the secondary handle located outside one end, so as to move while inserted in the body in configured shaft and, Harpoon that is installed on the shaft end to press the piston of the ampoule and, connected to the other end of the shaft configured includes a handle which is projecting in the body outside the syringe for local anesthesia, the handle is the located in the extension of the shaft, by a user's finger is in contact with the shaft to press the lateral pressure portion and price; A; secondary is pressure portion adapted to the price pressure portion laterally or to the position backward or side where the one selected from the rear contact your finger pressed into the side or rear or side of the shaft tip direction from the one selected area of ​​the rear of the price pressure portion of It shall be configured to include features. By the present design, index or middle fingers are in contact to form a stock price pressure portion which is located on the extension of the shaft in the handle for urging the piston with the thumb while the auxiliary handle to the supporting role separately, and the side or rear of the share pressure portion or by forming a secondary side pressure where any one of the selected backward Press, the price pressure in the initial pressure portion pressed by moving the thumb in the drug remains in the cartridge approximately 1/3 of the hard part is pressurized while pressurizing the secondary pressurized cartridge maximum power of the thumb dudeong near by jimyeo facilitated more drugs emissions, in particular, to the secondary pressurized section pressurized rather than do a fist clasped copper naturally that by forming a lateral or side rear of the price pressure portion erect erected pressing the thumb It can be pressurized by using it becomes easier to transfer the residual medicine in the cartridge. Further, in the auxiliary pressure unit price and can be easily pressed by using, by forming the rear of the pressure portion as much as possible the thumb dudeong near the first dorsal interosseous muscle, and to form a new himjeom the region apart from the first himjeom the price pressure portion cartridge it becomes easier to transfer the residual drug. ;
