Abstract

The invention relates to a disposable cervical dilation balloon catheter. The disposable cervical dilation balloon catheter effectively solves the problem that the existing cervical dilation can causediscomfort of patients. According to the technical scheme, the disposable cervical dilation balloon catheter comprises a catheter body, wherein the upper end of the catheter body is in a hemispherical shape, the outer portion of the upper half section of the catheter body is provided with a first balloon, a second balloon and a third balloon which are arranged in sequence from top to bottom, thecatheter body is internally provided with a rotating shaft, the upper end of the rotating shaft is provided with two sections of outer threads, each section of the outer thread is spirally provided with a first piston, the left side wall of the catheter body is provided with a first water injection pipe communicated with a cavity body in the lower end and the second balloon, the right side wall ofthe catheter body is provided with a second water injection pipe communicated with the first balloon, a chamber in the upper end, the third balloon and a chamber in the lower end, the cavity body inthe lower end is internally provided with a second piston sleeving the rotating shaft, the second piston is connected with the lower end of the catheter body through a compressed spring, the part, arranged outside the catheter body, of the rotating shaft is provided with a coiling wheel, the left side and right side of the coiling wheel are provided with pull ropes respectively, and the other endsof the pull ropes are fixed on the second piston.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable cervical dilation balloon catheter. 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 the prior art, the p...
