Abstract

本实用新型是一种对膀胱刺激性小的导尿管，注水阀通过注水腔与气囊相通，导尿管外口通过导尿腔与内口相通，使用时经注水阀注水2毫升－5毫升，气囊充盈展开形成圆柱状，与导尿管垂直成“T”形。既不易滑脱又减少了与膀胱颈部接触面积，减轻了对膀胱刺激。不易引起膀胱痉挛，从而减轻了病人痛苦。

Description

“T”形导尿管
(一)技术领域
本实用新型涉及一种医疗器械，具体地说是一种对膀胱刺激性小，不易滑脱的导尿管，适用于留置导尿与膀胱冲洗。
(二)背景技术
目前，医务工作者公知病人在留置普通气囊导尿管(气囊呈球形)时，均有不同程度的膀胱痉挛(膀胱内痉痛和尿道不适)症状，甚至病人难以忍受，给病人带来很大痛苦，是临床上比较棘手的问题。
(三)发明内容
本实用新型是为了克服现有普通气囊导尿管的易引起膀胱痉挛的不足而提供的一种“ T”形导尿管，该导尿管只有气囊两翼与膀胱颈部接触，从而减轻了对膀胱颈部的刺激，不易引起膀胱痉挛。
其实用新型解决其技术问题所采用的技术方案是：导尿管气囊展开前于普通导尿管没有什么区别，由注水阀注水时，水经注水腔充入气囊，使气囊展开成圆柱状，与导尿管垂直成“T”形注水量一般2毫升-5毫升，尿液由导尿腔内口经导尿腔从导尿腔外口流出。为了适应不同的需要可制成F12-F24(相当于导尿管直径4毫米-8毫米)的双腔(一个导尿腔一个注水腔)或三腔(两个导尿腔一个注水控)导尿管。
本实用新型的有益效果是：在留置导尿或膀胱冲洗时，最大限度地减少了气囊与膀胱颈部的接触面积，从而减少了对膀胱颈部的刺激，有效地避免膀胱痉挛，减轻病人痛苦，是普通气囊尿管的换代产品。
(四)附图说明
下面结合附图对本实用新型进一步说明。
图1是本导尿管气囊展开后的冠状切面示意图。
图2是导尿管气囊展开后的矢状切面示意图。
图3是导尿管的横截面示意图。
图中1导尿腔内口 2注水腔内 3柱状气囊
4注水腔 5导尿腔 6注水阀 7导尿腔外口
(五)具体实施方式
图一中，注水阀(6)、注水腔(4)与注水腔内口(2)相连，导尿腔外口(7)、导尿腔(5)与导尿腔外口(1)相连
使用时当尿管经尿道进入膀胱后经注水阀(6)注水2毫升-5毫升，气囊(3)展开如图(1)(2)所示，成圆柱状。

Claims (3)

1、一种导尿管，尿液由导尿腔内口经导尿腔从导尿腔外口流出，水阀通过注水腔与气囊相通，其特征是：经注水阀注水后，气囊展开呈圆柱状，于导尿管垂直成“T”形。
2、根据权利要求1所述的导尿管，其特征在于可制成F12-F24(相当于尿管直径4毫米-8毫米)不同规格以适用不同粗细的尿道。
3、根据权利要求1所述的导尿管，其特征在于导尿管尖端突出气囊3毫米-5毫米即可。
