Rapidly-withdrawn anesthetic needle

Abstract

The invention relates to a medical anesthetic needle, and particularly to a rapidly-withdrawn anesthetic needle. The rapidly-withdrawn anesthetic needle comprises a liquid bag, a connecting hose, a metal syringe, a conical pad and a needle head, wherein the liquid bag and the head end of the connecting hose are spliced and connected together; the tail end of the connecting hose and the head end of the metal syringe are spliced and connected together; the tail end of the metal syringe and the needle head are spliced and connected together; annular scale marks are curved on the exterior of the metal syringe; an outer screw thread is formed in the exterior of the metal syringe; the circular section at the upper part of the conical pad is constantly smaller than the circular section at the lower part of the conical pad; the conical pad comprises an upper hole, a lower hole, spring holes, springs and spring pads; the upper hole and the lower hole communicate with each other in a through manner; the upper hole and the lower hole are both provided with inner screw threads; and the conical pad is connected with the metal syringe through the mutual meshing of the inner screw threads and the outer screw thread. The anesthetic needle can be withdrawn rapidly, and convenience is brought to an anesthetist in an anesthesia operation, so that the rapidly-withdrawn anesthetic needle is suitable for popularization.

Description

technical field [0001] The invention relates to a medical anesthesia needle, in particular to a quick-draw anesthesia needle. Background technique [0002] At present, in the process of anesthetizing patients, because the original anesthesia equipment uses syringes for injection, when the needle is pulled out after use, the anesthetist's arm often shakes to a certain extent due to the long injection time, so that the needle is pulled out. Deviation or reverse insertion will cause further harm to the patient. Since the anesthesiologist uses the index finger, thumb, and middle finger to operate the syringe, defects such as inaccurate operation, shaking of the arm, and uneven force of the thumb during injection will occur as time goes by during the anesthesia operation, which will bring unpredictable results to the patient. s consequence. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a fast needle-drawing anes...
