The utility model relates to a guide for urethral catheter, which adopts 403 medical stainless steel wire with certain toughness and hardness, and one end of the stainless steel wire has radian to adapt to the curvature of human urethra. The top of the radian is provided with small balls, which support the catheter and slightly bring tension when the stainless steel wire penetrates the catheter. At the same time, iatrogenic damage can be avoided when conducting the catheter. Wound: The other end of stainless steel wire is made into a handle, one side of the handle is open and hooked, and the length of hook to the small ball is the length of the need for catheterization. The advantages are simple operation, easy to master, easy to obtain materials, low cost, stainless steel wire according to the size of the catheter used can be selected in a variety of models, high efficiency, reduce the suffering of patients, especially, solve the urgent problems caused by various reasons for patients with difficult catheterization.
【技术实现步骤摘要】
导尿管用引导器
本技术涉及一种导尿管用引导器,特别是涉及一种操作简单,易于掌握,取材方便,价格低廉,能避免造成医源性损伤;有多种型号可供选择的导尿管用引导器。
技术介绍
众所周知,男性尿道长,通常起自膀胱内口止于阴茎头的尿道外口,成人尿道长约16‐22cm,管径平均5‐7mm,整体尿道分为前列腺部位,膜部,海绵体部三部分,导尿时必须通过三个狭窄,三个膨大和两个弯曲,如无特殊异常的话,导尿管通过一般没有问题,但当出现以下状况时,导尿难度大大增加故导尿管通过很困难,如:①.尿道狭窄;②.较重的前列腺增生;③.尿道损伤:尿道连续性破坏,尿道全断裂患者;④.前列腺或者膀胱肿瘤术后;⑤.尿道痉挛;⑥.尿道结石患者。各种导尿困难患者如不能成功,接下来需要紧急行膀胱造瘘来解决患者排尿问题。一来增加患者痛苦及伤害风险;二来增加患者花费;三来患者问题并未解决,仍需要进一步解决尿道情况。故泌尿外科临床医生一直试图寻找一种增加导尿成功率的工具和方法。曾有同行做过使用自行车轴条消毒后插入导尿管来增加导尿成功率的尝试,确实增加了成功率,但同时也暴露了一些问题:1.自行车轴条缺少手柄设计,进 ...
