Abstract

The invention relates to an instrument for puncture and injection administration and belongs to the technical field of puncture and injection administration medical instruments. According to the instrument for puncture and injection administration, an arc needle hood can be controlled through a finger to control a needle to locate a delivery portion or a liquid extraction portion, the instrument is convenient to use, the finger of medical staff and a non-administration part can not be stabbed, and the instrument is particularly suitable for injection administration and liquid extraction detection at a complex position, is easy to operate and locate, avoids other damage, facilitates diagnosis and treatment, and lowers the operation difficulty coefficient.

Description

technical field [0001] The invention relates to a medical device, more specifically, the invention relates to a device for puncture and injection drug delivery, which belongs to the technical field of puncture and injection drug delivery devices. Background technique [0002] In the examination and treatment of obstetrics and gynecology, the following operations are often performed: during labor, when the cervix is ​​edema, give atropine to relax the cervix and reduce edema; Uterine wall injection of drugs; ectopic pregnancy, through vaginal fornix puncture, as the basis for judging ectopic pregnancy; uterine wall, intrauterine cyst, hematoma, through puncture to extract fluid for inspection. [0003] On August 3, 1988, the State Intellectual Property Office published a utility model patent with the publication number CN87215750 and the name "Uterine Muscular Injection Needle". There is a needle stem outside the myometrium, and a fixed handle is provided on the needle stem....
