Abstract

一种可变径穿刺引流管，包括可变径金属支架，所述可变径金属支架的内外壁均包覆有医用弹性硅橡胶层，所述可变径金属支架的内腔中装有等长的管状扩张气囊，所述管状扩张气囊内端封闭，外端具有充气嘴，通过充气嘴给管状扩张气囊充气，使可变径金属支架管径扩大后退出管状扩张气囊。本发明在临床上可以实现细径导管植入，再使导管直径变粗引流，使置管时对人体组织的损伤达到最小。而且细管径扩张后，对穿刺造成的微损伤亦有压迫止血作用。

Description

可变径穿刺引流管
技术领域
本发明属于医疗器械领域，具体涉及一种可变径穿刺引流管。
背景技术
临床治疗往往要通过各种导管来达到治疗目的，比如尿管、胃管、胸部闭式引流管、脑部引流管等等。这些导管的显著区别就是管径的不同，在临床上选择直径小的导管，对人体组织创伤小，病人的痛苦也小，但有时达不到治疗目的，选择直径粗的导管治疗，又会增加患者的创伤。另外在患者颅脑这些重要器官置管时，小直径导管的损伤导致颅内出血的几率明显降低，但是导管直径过小，又达不到引流颅内血肿或脑脊液的治疗目的，所以临床上粗直径导管的使用不可避免的增加了脑组织的创伤，而在颅脑疾病治疗中，这种创伤往往是致命的。目前没有良好的解决方案。目前在临床上还没有一种穿刺放置导管时直径小，穿刺成功后再使管径扩大，从而减少置管损伤的器械。
发明内容
本发明提供一种可变径穿刺引流管，在临床上可以实现细径导管植入，再使导管直径变粗引流，使置管时对人体组织的损伤达到最小。
本发明的技术解决方案：一种可变径穿刺引流管，包括可变径金属支架，所述可变径金属支架的内外壁均包覆有医用弹性硅橡胶层，所述可变径金属支架的内腔中装有等长的管状扩张气囊，所述管状扩张气囊内端封闭，外端具有充气嘴，通过充气嘴给管状扩张气囊充气，使可变径金属支架管径扩大后退出管状扩张气囊。
所述管状扩张气囊与可变径金属支架等长。
所述可变径金属支架为钛金属菱形支架。
本发明具有的优点和效果：
1、本发明在临床上可以实现细径导管植入，再使导管直径变粗引流，使置管时对人体组织的损伤达到最小。而且细管径扩张后，对穿刺造成的微损伤亦有压迫止血作用。
2、本发明用于颅脑穿刺引流，能减少粗导管植入颅脑引流时脑组织的损伤，降低颅内出血等并发症。此外，细管径扩大时，对穿刺造成的微损伤亦有压迫止血作用，更能减少穿刺后颅内出血的可能。
附图说明
图1为本发明的截面结构示意图，
图2为本发明扩张前的结构示意图，
图3为本发明扩张后的结构示意图。
具体实施方式
结合附图1、2、3描述本发明的一种实施例。
一种可变径穿刺引流管，包括可变径金属支架1，所述可变径金属支架1的内外壁均包覆有医用弹性硅橡胶层2，所述可变径金属支架1的内腔中装有等长的管状扩张气囊3，所述管状扩张气囊3内端封闭，外端具有充气嘴4，通过充气嘴4给管状扩张气囊3充气，使可变径金属支架1管径扩大后,再对管状扩张气囊3放气退出管状扩张气囊3。
所述管状扩张气囊3与可变径金属支架1等长。所述可变径金属支架1为钛金属菱形支架。
本发明植入前支架处于收缩状态，管径较细，当较细的导管植入到位时，通过充气嘴4给管状扩张气囊3充气，使可变径金属支架1管径扩大后退出管状扩张气囊3。达到细径导管植入后粗径导管引流的目的，对人体组织创伤小，病人的痛苦也小，又保证了治疗效果。此外，细管径扩大时，对穿刺造成的微损伤亦有压迫止血作用，更能减少穿刺后颅内出血的可能。
