Abstract

The invention relates to a cervical dilatation balloon catheter with a fluid storage function, which effectively solves the problem that the existing cervical dilatation can cause discomfort to the patients; the technical scheme of the balloon catheter comprises a catheter, a first balloon, a second balloon and a third balloon are arranged at the catheter in the order from top to bottom, a rotating shaft is arranged in the catheter, a retaining disc is arranged in the catheter, the retaining disc divides the catheter into upper and lower cavities which are mutually unconnected, the upper end of the rotating shaft is screwed with a first piston, a lower end is provided with a second piston, the second piston is connected with the first piston via an elastic drawstring, a left side wall interlayer of the catheter is provided with a first water injection pipe communicating with the lower cavity and the second balloon, and a right side wall interlayer of the catheter is provided with a second water injection pipe communicating with the first balloon, the upper cavity and the third balloon.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cervical dilation balloon catheter with a liquid storage function. Background technique [0002] Cervical dilatation balloon catheters are suitable for mechanical dilation of the cervix with poor maturity before labor induction. Cervical dilation balloon catheters usually need to be placed in the human body for a period of time. Gradually open to achieve the effect of induction of labor. The existing cervical dilatation balloon catheters all use one-time injection to prop up the balloon. This method directly opens the patient's cervix mechanically. Although the expansion speed is fast, However, this rigid expansion method will bring great discomfort to the patient. Therefore, a balloon catheter that can flexibly expand the patient's cervix is ​​urgently needed at this stage. Contents of the invention [0003] In view of the above situation, in order to overcome the defects of ...
