Puncture device for anesthesia

Abstract

The invention relates to the field of medical equipment, and particularly discloses a puncture device for anesthesia, which includes a needle with a handle, an infusion tube, a belt and an injection tube. shaped plate, a lock is provided between the free side of the upper arc plate and the lower arc plate, one end of the upper arc plate is connected to a lower pressing plate through a 7-type connecting rod, and the lower surface of the lower pressing plate is dug to hold The pressure groove of the needle; the injection tube is connected with the infusion tube, and the infusion tube is provided with a slide switch. Because the present invention is provided with slide switch, infusion tube, needle head and injection tube, can accomplish injection of anesthetic at any time, and because waist belt, upper and lower arc-shaped plate and lower pressure plate are provided with, injection tube and needle head can be fixed by cooperation between them, It is more convenient to carry out anesthesia work at any time. The invention has the advantages of simple structure, convenient use, controllable amount of anesthetic, long anesthesia time and good muscle relaxation.

Description

(1) Technical field [0001] The invention relates to the field of medical instruments, in particular to a puncture device for anesthesia. (2) Background technology [0002] At present, when patients undergo surgery below the lower abdomen, lumbar anesthesia or epidural anesthesia is mostly used. Waist anesthesia can obtain good muscle relaxation, which is beneficial to lower abdomen and pelvic surgery, but the anesthesia time is limited and cannot meet the anesthesia needs; External anesthesia can inject local anesthetic at any time to prolong the anesthesia time, but its relaxation degree is worse than that of lumbar anesthesia, which is not conducive to pelvic surgery. (3) Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provides a puncture device for anesthesia with controllable amount of anesthesia, long anesthesia time and good muscle relaxation. [0004] The present invention is achieved through the follow...
