Uterus salpingography tube

Abstract

The invention discloses a uterus salpingography tube. The uterus salpingography tube comprises an outer tube, a middle tube and an inner tube, wherein the outer tube is a hard tube; the middle tube is slidably nested in the outer tube, and the rear end of the middle tube extends out of the rear end of the outer tube; the inner tube is a hose, the inner tube is slidably arranged in the middle tube in a penetrating mode, an air bag is arranged at the front end of the inner tube, the air bag is located outside the front end part of the middle tube, the inner tube comprises a water injection channel and a medicine injection channel, the front end of the water injection channel communicates with the air bag, the front end of the medicine injection channel is open, and the rear end of the inner tube extends out of the rear end of the middle tube; and the front end of the outer tube, the front end of the middle tube and the front end of the inner tube are aligned, and the air bag is partially exposed out of the front end of the outer tube. The uterus salpingography tube has the advantages of being minimally invasive, simplified in operation, better in fixation, not prone to loosening and the like.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a hysterosalpingography tube. Background technique [0002] At present, due to the influence of environment, social factors and lifestyle, the incidence of infertility is increasing year by year. Among female infertility, tubal infertility accounts for a relatively high proportion. At present, ultrasonic hysterosalpingography (HSG) is widely used and has few side effects; hysterosalpingography (HSG) and fluid flow often use double-lumen balloon catheters or metal rod-shaped imaging devices. There will be problems such as difficult tube placement. Since the contrast tube needs to enter the uterine cavity, conventional doctors know the position of the patient's uterus and will use cervical forceps to clamp the anterior lip and posterior lip of the cervix, which is conducive to the smooth entry of the contrast tube into the uterine cavity, which will increase the operatio...

At present, ultrasonic hysterosalpingography (HSG) is widely used and has few side effects; hysterosalpingography (HSG) and fluid flow often use double-lumen balloon catheters or metal rod-shaped imaging devices. There will be problems such as difficult tube placement. Since the contrast tube needs to enter the uterine cavity, conventional doctors know the position of the patient's uterus and will use cervical forceps to clamp the anterior lip and posterior lip of the cervix, which is conducive to the smooth entry of the contrast tube into the uterine cavity, which will increase the operation time. , but also increase the pain of the patient
