Splicing type double-balloon contrast agent conveying pipe for salpingography

Abstract

The invention discloses a spliced double-balloon contrast agent delivery tube for salpingography, which comprises a delivery catheter connected to the inner side of a breather tube in a penetrating manner, a balloon tube nested on the outer side of the breather tube, and a drug delivery three-way catheter fixedly mounted at the rear end of the delivery catheter, the upper end of the conveying catheter is provided with a medicine inlet valve, the gas injection three-way catheter is fixedly installed at the rear end of the breather pipe, the upper end of the gas injection three-way catheter is provided with a gas injection sealing plug and a medicine injector, and the gas injection three-way catheter is installed on the rear side of the medicine conveying three-way catheter in a communicating mode. The spliced double-balloon contrast agent delivery tube for salpingography can be provided with two balloon structures at the same time, and contrast agents can be injected from the double delivery tubes at the same time, so that contrast observation can be conveniently carried out on uterine cavities of patients with double uteruses or complete mediastine uterus at the same time, discomfort of the patients is reduced, and the working efficiency of the patients is improved. And the radiography efficiency and quality are effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a spliced ​​double-balloon contrast agent delivery tube for salpingography. Background technique [0002] The contrast medium delivery tube is an interventional medical device, which injects contrast medium into the uterine cavity and fallopian tube through the catheter, so as to facilitate X-ray examination, fluoroscopy and radiography. To determine whether the patient's fallopian tubes are unobstructed, and to determine the shape of the uterine cavity, so as to diagnose whether there is intrauterine adhesions and foreign bodies. [0003] In order to facilitate the opening of the uterine cavity or fallopian tube, the existing contrast medium delivery tube has a balloon catheter attached to the delivery tube, which can be inflated and expanded inside the balloon catheter to support the blocked site, while the existing contrast medium delivery tube only has There is a sin...

Problems solved by technology

[0004] The object of the present invention is to provide a spliced ​​double-balloon contrast medium delivery tube for salpingography, to solve the problem that the existing contrast medium delivery tube proposed in the above-mentioned background technology only has a single balloon structure, and the single delivery tube Only one uterine cavity can be entered at a time, and for patients with double uterus or complete septate uterus, repeating the steps of operating the common contrast medium delivery tube will cause discomfort to the patient, and also reduce the use efficiency of the contrast medium delivery tube and quality issues
