Abstract

The invention relates to a device for puncture and injection drug delivery, belonging to the technical field of puncture and injection drug delivery devices. The instrument for puncture and injection drug delivery can control the position of the needle for drug delivery or liquid extraction by controlling the arc-shaped needle cover with fingers. It is easy to use and will not puncture the fingers of medical staff and non-medication locations, and is very suitable for complicated positions. It is easy to operate, easy to locate, and will not cause other damage, which is convenient for diagnosis and treatment, and reduces the degree of difficulty of operation.

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....
