Abstract

一种临床上免内镜取管的磁性双J管及拔管器。磁性双J管包括双J管和强力磁铁圈两部分，拔管器包括软管、强力磁铁两部分。进入膀胱的软管，其头部内嵌有强力磁铁，能够吸住双J管的强力磁铁圈，从而把双J管拉出。设计合理，结构简单，安全可靠，方便门诊操作，免除患者用内窥镜取管的痛苦和麻烦，免除麻醉手术的时间和费用。

Description

磁性双J管及拔管器
所属技术领域
本实用新型涉及医疗器械技术领域，一种临床上免内镜取管的磁性双J管及拔管器。
背景技术
双J管(输尿管支架管)因具有支撑及引流的双重作用，在国内各医院均得到广泛应用。许多医院在泌尿系手术时常规放置双J管取代过去的经腹壁输尿管或肾盂造瘘，因为后者可能导致造瘘口渗尿、输尿管弯曲成角或狭窄等并发症。此外，双J管放置时间可长可短，病人可以先出院，以后在门诊行膀胱内窥镜拔管。但膀胱内窥镜是刚性器械，检查及拔管会增加患者的痛苦和麻烦，增加尿道及膀胱损伤和感染的机会。另外，到手术室局麻拔除双J管加上消炎等治疗，需要费用近千元，给患者加重了经济负担。
发明内容
为了克服膀胱内窥镜取双J管不方便、不舒适、不经济的问题，本实用新型提供一种简便、安全、经济的免内镜取管的磁性双J管及拔管器。
本实用新型解决其技术问题所采用的技术方案是：
磁性双J管由双J管和强力磁铁圈两部分组成，拔管器由软管、强力磁铁两部分组成。
1、在双J管膀胱的一端内嵌强力磁铁圈，其外径1.5mm，内径0.83mm，方便磁性拔管器寻找和吸出。
2、进入膀胱拔管的软管由柔软的硅胶材料制成，克服刚性镜体对尿道的刺激和损伤。
3、软管外径5.3mm，能够略有余地的进入尿道。其头部内嵌有强力磁铁，吸力在100g以上，而双J管只有30g，加上在输尿管及尿道的阻力不超过100g。
本实用新型的有益效果是设计合理，结构简单，安全可靠，方便门诊操作，免除患者用内窥镜取管的痛苦和麻烦，免除麻醉手术的时间和费用。
附图说明
下面结合附图，对本实用新型进一步说明。
图1是本实用新型的结构示意图。
图2是本实用新型的结构剖面图。
图中1、双J管；2、强力磁铁圈；3、强力磁铁；4、拔管器软管。
具体实施方式：
在图1-2中，双J管(1)在双J管膀胱的一端内嵌强力磁铁圈(2)，拔管器软管(4)其头部内嵌有强力磁铁(3)，当拔管器软管(4)进入膀胱，强力磁铁(3)便吸住双J管(1)上面的强力磁铁圈(2)，从而把双J管(1)拉出。
