Disposable balloon catheter for cervical dilation

Abstract

The invention discloses a disposable balloon catheter for cervical dilation. The disposable balloon catheter comprises a guide wire and a dilation balloon, the dilation balloon comprises a connector,a hose and a connecting screw, wherein the connector, the hose and the connecting screw are connected with the guide wire, and the dilation balloon further comprises a connecting rod, a dilation assembly and a filling head, wherein the connecting rod is connected with the connecting screw, and the dilation assembly is arranged in the connecting rod; a medium filling channel is formed in the end, facing the hose, of the filling head, and the connector, the hose and the connector are sequentially and internally communicated; the dilation assembly comprises a buckle and a silicone tube which is sleeved with the buckle, the tail end of the silicone tube is extended through the filling head, and an inner cavity of the silicone tube is communicated with the medium filling channel. Through the connecting screw and the connecting rod, the hose and the dilation assembly are connected more conveniently; the hose is supported through the guide wire, so that the dilation balloon is conveniently and smoothly delivered into the cervix uteri; for a patient needing repeated cervical dilation, the hose is adopted for making the dilation balloon without the guide wire indwell in the cervix uteri, itis unnecessary to frequently replace the balloon catheter with a new disposable balloon catheter for cervical dilation, paints of the patient are reduced, and damage to the cervix uteri mucosa is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable cervical dilatation balloon catheter. Background technique [0002] When performing family planning operations, gynecological examinations, or operations on the vaginal uterus and its accessories, the cervical canal must be dilated in order to better meet the needs of the operation. At present, the method of dilating the cervical canal in the prior art is: using metal or plastic uterine dilating rods with different diameters, inserting them into the cervix in order from small to large, pulling them out, and hard dilating the cervix to reach the size of the cervix for surgery. The doctor’s operation is very cumbersome and may cause damage to the cervical mucous membrane; or use certain materials to expand the cervix through the moistening of the cervical mucus to expand the cervical canal. This method is related to the secretion of the cervix, and the dilating...
