Disposable uterine cavity medicine injecting tube

Abstract

The invention discloses a disposable uterine cavity medicine injecting tube which comprises an outer tube and an inner tube. The outer tube is provided with a mushroom-shaped head, a thread and an anchoring bolt from left to right, the left end is made of hard plastic, the part, from the position 2-4 cm away from an end point to the right, of the left end is made of soft plastic, the part made of the soft plastic is longitudinally provided with a gap along one circumference of the wall of the outer tube, and a flower basket shaped cavity is automatically formed when two ends of the part made of the soft plastic are subjected to opposite forces. The left end of the inner tube is connected with a medicine output head, and the right end of the inner tube is movably connected with a medicine injecting head. The cervix uteri orifice is fixed without pincers, the cervix uteri is not hurt, and injection is not likely caused. Manual medicine injecting tube fixing is not needed in the medicine injecting process, and radioactive hurts to an operating doctor are decreased. The medicine outlet head of the medicine injecting tube is made of the hard plastic, and can also smoothly enter the uterine cavity of a patient having the narrow cervix uteri orifice or the slightly adhered cervix uteri orifice, and the medicine liquid leakage problem in the medicine injecting process and after medicine injection is completely eradicated by adopting the double seal measures, namely the flower basket and the mushroom-shaped head.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable intrauterine drug injection tube. Background technique [0002] When performing hysterosalpingography and treating gynecological diseases, it is necessary to inject medicine or contrast agent into the uterine cavity through the cervix. The traditional method is usually to make the patient take the bladder lithotomy position and lie supine on the X-ray machine operating platform or gynecological examination bed. After the operator checks the position and size of the uterus, the vulva and vagina are routinely disinfected; Use 2% red mercury for cervical and vaginal disinfection, then use cervical forceps to gently hold up the cervix and fix it with clamps. The operator will extend the injection tube with mushroom head into the cervical opening 2 cm and hold the injection tube with one hand. Push the drug tube into the uterine cavity to make the mushroom head block the c...

Problems solved by technology

This method will cause serious physical damage to the cervix and is prone to cross-infection, and the operator needs to manually fix the injection tube and the cervix when taking X-ray photos, and X-rays will cause radiation damage to the operator

[0003] The "disposable hysterography water pipe" produced by Zhanjiang Shida Industrial Co., Ltd. basically eliminates the disadvantages of the traditional method. Or for patients with mild cervical adhesions, it is difficult to enter the uterine cavity, and traditional methods are still needed for remediation; in addition, because the aqueduct enters the uterine cavity, an air bag is bulged to seal the aqueduct, and the cervix Without any sealing measures, it is difficult to avoid the leakage of medical solution or contrast medium
