Disposable balloon catheter for cervical dilation

Abstract

The invention discloses a disposable balloon catheter for cervical dilation. The disposable balloon catheter comprises a pressurizing assembly and a dilation balloon, the dilation balloon comprises acatheter body connected with the pressurizing assembly, a connecting assembly connected with catheter body, a dilating assembly arranged in the connecting assembly and a filling head, and a medium filling channel is formed in the end, facing the catheter body, of the filling head; the connecting assembly comprises a connecting rod connected with the catheter body and a connecting screw arranged inside the connecting rod; the dilating assembly comprises a buckle and a silicone tube sleeved with the buckle, the end, back on to the catheter body, of the filling head penetrates through the buckleand extends the tail end of the silicone tube, and an inner cavity of the silicone tube is communicated with the medium filling channel. Through the connecting assembly, the catheter body and the dilating assembly are connected more conveniently; through the filling head, the length of the silicone tube is increased, and the outer diameter of the silicone tube is reduced; the silicone tube expandsoutwards to dilate the cervix uteri, the pains of a patient are reduced, damage to the cervix uteri mucosa is reduced, and therefore it is ensured that cervical dilation is performed safely and smoothly.

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...

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 effect is often Not good, it is not conducive to the safe and smooth operation process
