Abstract

本实用新型公开了一种用于输送介入治疗先天性心脏病封堵器的封堵器输送导管，该封堵器输送导管包括内芯和长外套管，内芯位于长外套管内，长外套管后端与长外套管接头前端相连，其特征是长外套管接头后端通过双螺纹与内芯接头前端相连。接头连接处采用双螺纹结构，在使用过程中，密封效果明显改善，解决了渗漏缺陷。此接头材料为ABS工程塑料，只要开好注塑模具即可，生产加工实施起来非常容易。

Description

封堵器输送导管
技术领域
本实用新型涉及一种用于输送介入治疗先天性心脏病封堵器的输送导管。
背景技术
公知的一次性封堵器输送导管，是用于输送介入治疗先天性心脏病封堵器的专用器械，主要由进入体内血管的长鞘和装载封堵器的短鞘及防漏装置三大部分组成。输送导管的接头主要是连接各管道，接头连接处采用单螺纹结构。在心脏病介入手术过程中由于体内血液压力的作用，采用单螺纹结构在管道之间的接头会出现血液渗漏现象。
发明内容
本实用新型的目的是要提供一种封堵器输送导管，该封堵器输送导管的接头连接处不会出现渗漏现象。
本实用新型的目的是这样实现的：该封堵器输送导管包括内芯和长外套管，内芯位于长外套管内，长外套管后端与长外套管接头前端相连，长外套管接头后端通过双螺纹与内芯接头前端相连。
本实用新型接头连接处采用双螺纹结构，在使用过程中，密封效果却明显改善，解决了渗漏缺陷。此接头材料为ABS工程塑料，只要开好注塑模具即可，生产加工实施起来非常容易。
附图说明
图1是本实用新型一个实施例的结构示意图。
图2是图1中的长外套管接头结构示意图。
图中1.内芯、2.长外套管、3.长外套管接头、4.内芯接头、5.双螺纹。
具体实施方式
在图1和图2中，该封堵器输送导管包括内芯1和长外套管2，内芯1位于长外套管2内，长外套管2后端与长外套管接头3前端相连，长外套管接头3后端通过双螺纹5与内芯接头4前端相连。
