Description

A kind of for puncturing and the apparatus of drug administration by injection
Technical field
The present invention relates to a kind of medical apparatus and instruments, more particularly, the present invention relates to a kind of for puncturing and the apparatus of drug administration by injection, belonging to puncture and drug administration by injection technical field of medical instruments.
Background technology
In the inspection and treatment of department of obstetrics and gynecology, often to proceed as follows: in stages of labor, during cervical edema, give the lax cervix uteri such as atropine, alleviate edema; During artificial abortion, give palace other local anesthesia; During uterine contractions fatigue in puerperal, by palace wall injectable drug; During ectopic pregnancy, by puncture of posterior fornix of vagina, as the foundation judging ectopic pregnancy; Uterus wall, intrauterine cyst, hematoma, checked by puncture extracting liquid.
It is CN87215750 that State Intellectual Property Office discloses a publication number in 1988.8.3, name is called the utility model patent of " syringe needle for myometrium ", this patent is by needle point, pin obstructs, the entry needle of pintle composition, prolongation and overstriking are exposed at the pin stalk of myometrium outside, and fixed handle is provided with on pin stalk, the outside of entry needle is added with protective casing, uterine cavity can be stretched into, thrust the direct injection of medicine of myometrium, cannot in the difficulty of the direct injection of medicine of myometrium during caused by uterine inertia massive hemorrhage when solving vaginal delivery, and be applicable to the Other diseases for the treatment of body of uterus.
Above-mentioned uterus muscle syringe is provided with protective casing, is convenient to stretch into cavity of uterus, but its needle point is unfavorable for location, is not suitable for the drug administration by injection of the complicated position such as Uterus wall, cervix uteri, and easily stabs finger and the non-administration position of medical worker.
It is CN202459753U that State Intellectual Property Office discloses a publication number in 2012.10.3, name is called the utility model patent of " a kind of obstetrics and gynecology department uterine probe ", this patent relates to a kind of obstetrics and gynecology department uterine probe, comprise the handle of needle body and needle rear end, wherein, needle body is the tubular body of hollow, the nose threads of needle body is connected with oval probe, probe inner hollow and outer wall is provided with liquid outlet, the rear end of handle is provided with the syringe connecting hole be communicated with needle body inside, and the end of syringe connecting hole is provided with sealing-plug.This utility model outstanding advantages is: structure is simple, and the front end of needle body is provided with oval probe, use safety, not easily scratches Uterus wall and other uterine cancer cell; Needle body is the tubular body of hollow, two ends are respectively with the syringe connecting hole of handle rear end and probe is inner and liquid outlet is communicated with, syringe can be connected by syringe connecting hole, indicator or other liquid medicines is injected to intrauterine, indicator or other liquid medicines enter inside, uterus from liquid outlet, carry out inspection or the treatment in uterus.
It is CN204293670U that State Intellectual Property Office discloses a publication number in 2015.4.29, and the utility model patent that name is called " intrauterine injection syringe needle ", this patent type relates to intrauterine injection syringe needle.This utility model shank and syringe needle are approximate right angle shape, and pin hole is in needle tip.This utility model overcomes existing injection needle to be existed and cannot inject, sidewall forward and backward to uterus in uterine cavity through cervix uteri, injection depth also uncontrollable defect simultaneously.This utility model directly can enter uterine cavity through cervix uteri, the cut to lengthen liquid medicine injection bent by syringe needle is in the degree of depth of Uterus wall and inner membrance and muscle layer joint, syringe needle can fluid, the bearing mark of syringe is connected by syringe needle, reach the instruction being injected in antetheca, rear wall, sidewall, can, sidewall liquid medicine injection forward and backward in uterus.
Although above-mentioned first section of uterine probe of the prior art can not stab finger and the non-administration position of medical worker, indicator or other liquid medicines are just injected into inside, uterus by this probe, can not carry out intramuscular injection; Although second section of injection needle of the prior art can to the complicated medicine-feeding part administration injection such as Uterus wall, cervix uteri, its structure not easily stretches into uterus, exists too and not easily locates, and easily stabs the finger of medical worker and the problem of non-administration position.And above-mentioned all prior aries do not possess the function of puncture, cannot check by extracting liquid.
Summary of the invention
The present invention is intended to the more difficult site-specific delivery of drugs position of injection of uterus equipment solving prior art, be not suitable for uterus, the other tissue in palace, or liquid is got in drug administration by injection and the puncture of other complicated positions, and easily stab the finger of medical worker and non-administration, get the problem that liquid level puts, there is provided a kind of for puncturing and the apparatus of drug administration by injection, this apparatus can control syringe needle site-specific delivery of drugs by finger or get liquid position, easy to use.
