Abstract

The invention belongs to the technical field of anesthesia device, in particular relates to a surface anesthesia needle tubing and using method thereof. The surface anesthesia needle tubing comprisesa cylinder body, a connecting cylinder is arranged at the lower end of the cylinder body, the outer side of the connecting cylinder is provided with a first external thread, the connecting cylinder isprovided with a fixing cylinder, the inner side surface of the fixing cylinder is provided with a first internal thread matched with the first external thread, the outer wall of the upper part of thefixing cylinder is integrally formed with a hexagon block, the lower part of the fixing cylinder is provided with a slot, the surface of the slot is provided with a drug injection hole, the card is positioned between the two side plates, the right end of the card is provided with a strip-shaped notch, the card right end through-hole strip-shaped notch is stuck on the card board, the card column is positioned on the end face of the right end of the card, the portion of a screw rod, on the upper end face of a thread bushing, is sleeved with an inverted L-shaped ruler plate, the outer wall of the upper part of the side plate is provided with a graduation line matched with the inverted L-shaped ruler plate, and the upper end of the central rod is detachably connected with a handle. The aim ofthe surface anesthesia needle tubing is to solve the problems of uncontrollable anesthesia range caused by the existing epidermal anesthesia device structural defects, waste of anesthesia drugs and difficulty in extracting anesthesia medicines.

Description

Technical field [0001] The invention belongs to the technical field of anesthesia equipment, and specifically relates to a surface anesthesia needle tube and a use method thereof. Background technique [0002] In long-term clinical practice, for epidermal anesthesia or regional anesthesia, drugs are sprayed onto the patient’s skin for anesthesia. However, the existing spraying measures are too large when used, which will increase the scope of anesthesia and waste anesthetic drugs. It is also troublesome for the patient to recover the excess anesthesia range. When the medical staff is taking the medicine from the needle cannula, the pressure in the needle is too high and the medical staff needs to instill it hard, which makes the work more difficult for the medical staff. Summary of the invention [0003] The purpose of the present invention is to provide a surface anesthesia needle tube and its use method to solve the problems of uncontrollable anesthesia range caused by structura...
