Abstract

本实用新型涉及一种输尿管支架管,它主要适用于人体输尿管支撑及引流。本实用新型包括管体主段1,管体卷曲段2、3,弹性卡扣4、5,单向引流阀6。其特征在于:管体卷曲段起始部存在弹性卡扣4、5,遇一定张力闭合,进入肾盂或膀胱时张力降低,弹性卡扣4、5开放,从而固定管体。管体下端单向引流阀6使得液体从肾盂向膀胱当方向引流,逆流时引流阀关闭。本实用新型结构设计合理,符合生理特性,使用方便,效果好。

Description

新型输尿管支架管
技术领域
本实用新型涉及一种输尿管支架管,它主要适用于人体输尿管支撑及引流。
背景技术
现临床常用的输尿管支架管即双J管管体两端卷曲呈圆形,从而起到固定管体,防止支架管向上蠕动或向下滑脱,但此输尿管支架管在实际应用中存在管体卷曲段管体延伸变直引起管体上移和下滑现象。管腔内壁光滑连续引流尿液,但破坏了输尿管下端抗反流生理机制。
发明内容
为了克服上诉输尿管支架管的弊端,本实用新型提供一种新型输尿管支架管,该输尿管支架管不仅可以增加管体的位置稳定性,减少下滑和上移,还可以使得引流液单向流动,更加符合人体生理特性。
本实用新型采用的技术方案是是:管体两端向相反方向卷曲一圈,分别在卷曲起始段管壁存在环形弹性卡扣。支架管下端卡扣上方管腔内存在单向引流阀。当临床医师在放置或者取出支架管时,弹性卡扣可以遇一定张力闭合。卡扣进入肾盂或膀胱时张力降低,弹性扣开放,从而固定管体。管体下端单向引流阀使得液体从肾盂向膀胱当方向引流,逆流时引流阀关闭。
附图说明
附图为本实用新型的结构图示意图。
具体实施方式
以下结合附图对本实用新型做进一步详细描述。本实用新型包括管体主段1,管体卷曲段2、3,弹性卡扣4、5,单向引流阀6。其特征在于:管体卷曲段起始部存在弹性卡口4、5,遇一定张力闭合,进入肾盂或膀胱时张力降低,弹性卡扣4、5开放,从而固定管体。管体下端单向引流阀6使得液体从肾盂向膀胱当方向引流,逆流时引流阀关闭。

Claims (1)

1.一种输尿管支架管,管体两端向相反方向卷曲一圈,分别在卷曲起始段管壁存在环形弹性卡扣,支架管下端卡扣上方管腔内存在单向引流阀,其特征是两端卡扣与卷曲起始部位相连续,遇到张力卡扣可向管壁靠拢回缩,管腔内引流液体只能向一个方向流动。
