Disposable cervical dilatation balloon catheter

Abstract

The invention discloses a disposable cervical dilatation balloon catheter. The catheter comprises a pressurizing assembly and a dilatation balloon which are connected; when cervical dilatation is carried out, through a guiding effect of a sleeve, a hose enters a vagina along with a connecting assembly, a filling head and a dilatation assembly, the dilatation balloon is filled with gas or liquid through the pressurizing assembly, the gas or liquid sequentially passes through the hose, a connecting channel and a medium filling channel to enter the dilatation assembly, and the dilatation assembly expands outwards to dilate a cervix uteri, so that the cervix uteri is slowly expanded to a size ensuring a smooth operation at a time, the pain of a patient is relieved, the damage to cervix uteri mucosa is reduced, and a uterus dilatation process can be carried out safely and smoothly; and when cervical dilatation is finished, a one-way valve is pulled outwards, the sleeve is taken down, and the dilatation balloon is reserved by folding the hose. According to the catheter, the whole structure is good in sealing performance, the leakage is not prone to happen, and the operation is convenient.

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. The traditional method of dilating the cervical canal is: use metal or plastic dilating rods with different diameters, insert them into the cervix in order from small to large, pull them out, and hard dilate the cervix to reach the size of the cervix for surgery. It may cause damage to the cervical mucous membrane; or use certain materials to expand the cervix to expand the cervical canal through the moistening of the cervical mucus. This method is related to the secretion of the cervix, and the expansion effect is often not good, which is not conducive to surgery The process is ...

Problems solved by technology

[0004] Although the above-mentioned disposable cervical dilatation balloon catheter has the advantages of reducing the pain of the patient, reducing the damage to the cervical mucosa, ensuring the safe and smooth progress of the uterine dilation process, and can also be placed in the vagina, etc., but when used, it is necessary to The guide wire is pressed into the one-way valve. This connection method will damage the one-way valve core, which may cause the one-way valve to fail and leak water. In addition, when the dilation of the cervix ends, the guide wire needs to be pulled out. The operation steps are cumbersome, and Silicone stoppers may leak
