Description

一种脑脊液穿刺引流器
                         技术领域
本发明涉及一种医疗设备，特别是一种脑脊液穿刺引流器。
                         背景技术
蛛网膜下腔出血和脑室出血是常见脑血管疾病。其特点为突发头痛、呕吐、精神异常或意识障碍等为首发症状。血液积聚于脑室系统和蛛网膜下腔，引起脑室铸型、脑脊液循环受阻、急性高颅压症甚至脑疝死亡。幸存者常因积血的再吸收致脑血管痉挛、正常颅压脑积水、多数颅神经炎和脊髓蛛网膜炎等并发症，导致严重后果。因此，及时清除积血、输通脑脊液循环是早期救治的关键。但现用的引流管或引流方法难以达到侧脑室以远的第三、四脑室，引流效果不佳。而用腰椎穿刺进行脑脊液置换，以达到清除蛛网膜下腔积液的目的，但抽取脑脊液后不能留置和持续引流，只有反复穿刺才能清除蛛网膜下腔不断产生的积血，增加了病人的痛苦和损伤，有时还会加重病情，增加感染机会，更不能随时观察蛛网膜下腔的出血情况及压力变化，其引流效率也低。
                      发明内容
本发明要解决的技术问题是针对现有技术的不足，提出了一种临床上用于腰大池穿刺和脑室穿刺的脑脊液穿刺引流器。
本发明要解决的技术问题是通过以下技术方案来实现的，一种脑脊液穿刺引流器，它包括穿刺设备和外设的引流装置，其特点是：所述的穿刺设备设有穿刺针芯、穿刺针鞘、导丝和引流管，
穿刺针芯和针鞘由不锈钢材料制成，针鞘套装于针芯外，共同用于穿刺；
导丝用于替换针芯，导丝由塑刚材料制成，柔软便于塑形，并有形状记忆功能；
引流管用于置换针鞘和引流，引流管由柔软的硅胶制成，顺应性好，管头圆钝，以减少组织损伤，便于沿导丝外径送入需引流的腔室内。
针鞘套装于针芯外用于穿刺，当刺入适当位置时，取出针芯，将导丝从针鞘的内孔穿入，再将针鞘从体拔出，再将引流管沿导丝外径送入需引流的腔室内，或在DSA监视下送入侧脑室以远的更深部位。
本发明要解决的技术问题还可以通过以下技术方案来进一步实现，引流管的外端通过导管与外设的引流装置相接，导管上装有控液阀。
本发明要解决的技术问题还可以通过以下技术方案来进一步实现，引流管的前端管壁上开有2-5个侧引流孔，以增加引流速度，避免血块堵管。
本发明要解决的技术问题还可以通过以下技术方案来进一步实现，所述的针芯是中空的注射式针芯，后端连接有一个观察室。以便于观察是否有脑脊液流入。
本发明要解决的技术问题还可以通过以下技术方案来进一步实现，所述的引流装置设有一个脑脊液引流袋，脑脊液引流袋的上部设有悬挂装置，脑脊液引流袋的底部向内装有一个引入管，引入管下端与所述的导管相接，引入管的上端口距穿刺点的高度为10~18cm，脑脊液引流袋的下部还与一个集液袋相连通，引入管上标有刻度。通过对引入管上端口与穿刺点高度的控制，可以控制需引流的腔室的压力，减少并发症的发生机率。
本发明要解决的技术问题还可以通过以下技术方案来进一步实现，所述的穿刺针鞘、导丝和引流管的外表面都标有刻度。以便于观察刺进深度。
