Abstract

本实用新型涉及一种双腔脑内血肿专用冲洗导管，包括管体和与管体连通的管接头，管体内腔设计为双腔，即注液腔和出液腔，在靠近管体端头部位处的一侧管壁上设有与管体注液腔连通的进液孔，于另一侧管壁上设有与出液腔连通的出液孔，所述注液腔尾部和出液腔尾部分别连接有注液腔管接头和出液腔管接头。优点是：管体设计为双腔，有利于术中或术后同时进行残余血肿的冲洗和引流，可尽快清除患者颅内残余血肿，经临床使用对于患者颅内的残余血肿的清除起到了很好的疗效。明显降低了微创手术后病人的死亡率和致残率。

Description

双腔脑内血肿专用冲洗导管
技术领域
本实用新型属于医疗器械技术领域，特别是涉及一种用于颅内手术可同时进行血肿冲洗和引流、操作简便快捷的双腔脑内血肿专用冲洗导管。
背景技术
由于我国社会老龄化问题的日趋严重，高血压脑出血已成为我国人口三大疾病致死原因之一，随着医疗事业的不断发展，临床上治疗高血压脑出血的方法也由过去的开颅手术向立体定向、转颅、小骨瓣显微镜下清除血肿的方向发展。目前微创手术治疗高血压脑出血后，均在血肿腔放置引流管，以达到引流残余血肿的目的，而引流残余血肿使用的是单腔血肿腔引流管，此种引流管由于是单腔结构，且不能尽快清除残余血肿，只能等待残余血肿溶解后方可引流。若残余血肿不能及时清除会对患者造成诸如：血肿内分解的有毒成分会加重对周围正常脑组织的损害，加重脑水肿等不利后果，由此会增加患者的致死率和致残率。
发明内容
本实用新型为解决公知技术中存在的技术问题而提供一种用于颅内手术可同时进行血肿冲洗和引流、操作简便快捷的双腔脑内血肿专用冲洗导管。
本实用新型为解决公知技术中存在的技术问题所采取的技术方案是：
双腔脑内血肿专用冲洗导管，包括管体和与管体连通的管接头，其特征在于：管体内腔设计为双腔，即注液腔和出液腔，在靠近管体端头部位处的一侧管壁上至少设计有三个与管体注液腔连通的进液孔，于另一侧管壁上至少设计有三个与出液腔连通的出液孔，所述注液腔尾部外口和出液腔尾部外口分别连接有注液腔管接头和出液腔管接头。
本实用新型还可以采用如下技术措施：
所述的管体和管接头均采用高分子医用材料制作。
本实用新型具有的优点和积极效果是：由于本实用新型将冲洗管管体设计为双腔，即注液腔和出液腔，因此有利于术中或术后可以同时进行残余血肿的冲洗，可尽快清除患者颅内残余血肿，避免了单管引流术的缺陷。此专用冲洗导管具有很强的临床使用价值，经临床使用对于患者颅内的残余血肿的清除起到了很好的疗效。明显降低了微创手术后病人的死亡率和致残率。
附图说明
图1是本实用新型的结构示意图；
图2是图1的K-K剖视图。
图中：1管体、2注液腔、3进液孔、4出液腔、5出液孔、6注液腔管接头、7出液腔管接头。
具体实施方式
为能进一步了解本实用新型的发明内容、特点及功效，兹例举以下实施例，并配合附图详细说明如下：
请参阅图1和图2，双腔脑内血肿专用冲洗导管，包括管体1和与管体连通的管接头，管体1内腔设计为双腔，即注液腔2和出液腔4，在靠近管体端头部位处的一侧管壁上至少设计有三个与管体注液腔连通的进液孔3，于另一侧管壁上至少设计有三个与出液腔连通的出液孔5，所述注液腔尾部外口和出液腔尾部外口分别连接有注液腔管接头6和出液腔管接头7，注液腔管接头6可与注射器连接，出液腔管接头7连接引流管。所述的管体和管接头均采用高分子医用材料制作。
本实用新型的动作原理说明如下：使用时，通过注液腔2注入无菌的生理盐水，从进液孔3进入患者颅内冲洗残余血肿，经出液腔上的出液孔5进入出液腔4，出液腔由出液腔管接头7接无菌引流装置，冲洗后的液体自出液腔流出。
