Side air bag.But the urethral catheterization chamber of this catheter easily blocks, and needs again to change catheter, bring misery to patient after blocking.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, it is provided that leading of a kind of built-in seal wire
Urinary catheter, is possible to prevent catheter to block, and is not required to often change catheter, alleviates patient suffering.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is to be achieved through the following technical solutions:
The catheter of a kind of built-in seal wire, including urethral catheterization body and set seal wire in the inner, the front end of described urethral catheterization body
It is provided with a contractile sacculus, in the middle part of described sacculus inwall, is provided with endless drive loop, described sacculus runs through offering at least
One urethral catheterization hole, the middle part of described drive belt is provided with spacing hole, and the front end of described seal wire is provided with spherical top, is positioned at spherical top
Lower section be provided with driving bulge loop, when the spherical top of described seal wire is along catheter intracoelomic cavity upward sliding to inwall top, institute
State driving bulge loop to offset with drive belt and drive it to move upward, correspondingly the most inside with the sacculus that described drive belt is connected
Shrink.
Further, described urethral catheterization body, sacculus and endless drive loop are structure as a whole.
Further, described sacculus, with drive belt place plane as the plane of symmetry, offers at least two groups along its perimembranous symmetry
Urethral catheterization hole.
Further, described seal wire, spherical top and driving bulge loop are structure as a whole.
Further, the diameter of described spherical top is less than the diameter of spacing hole, and the diameter of described driving bulge loop is more than limit
The diameter in hole, position.
The beneficial effects of the utility model are:
1, seal wire inserts urethral catheterization body and drives its entrance bladder, and the spherical top of its front end slides up along catheter intracoelomic cavity
When moving to inwall top, driving bulge loop can offset with drive belt and drive it to move upward, sacculus, therewith to contract, will not hinder
Urethral catheterization body is hindered to enter bladder；After urethral catheterization body enters bladder smoothly, extracting seal wire, sacculus is in itself and the elastic shape of drive belt
Under change effect, meeting reinstatement, can effectively replace air bag to fix urethral catheterization body.
2, the many groups urethral catheterization hole outside sacculus is beneficial to urinate, and internal spacing hole diameter design is reasonable, does not interferes with seal wire
Insertion and extract.
Certainly, implement arbitrary product of the present utility model to it is not absolutely required to reach all the above advantage simultaneously.
