Description

一种能够暂时保存脑脊液的装置 技术领域
本发明涉及医疗卫生用品技术领域，具体为一种能够暂时保存脑脊液的装置。
背景技术
神经科医生在抽取病人的脑脊液时，为了防止被感染，一般都穿戴防护服、佩戴橡胶手套进行操作。由于没有专用的脑脊液抽取工具，一般使用传统的注射器进行抽取。传统的注射器一般包括带有穿刺针的注射筒，注射筒内滑动密封插装有连接在一起的密封塞和推拉杆。通过抽拉推拉杆，可以驱动密封塞在注射筒内滑动，从而实现对脑脊液的抽取和排放。脑脊液抽取后，一般都会推入试管中或直接用注射器暂存。而直接用注射器暂存脑脊液时，暴露于大气中的穿刺针不但不安全，而且容易导致脑脊液挥发，因此只适合短时间暂存。由于传统注射器没有锁紧装置，使用传统注射器暂存脑脊液时，如果不小心碰到推拉杆或误操作，容易将脑脊液推射出来，很不安全。
发明内容
本发明的目的在于提供一种能够暂时保存脑脊液的装置，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：一种能够暂时保存脑脊液的装置，包括注射器、针头和针头栓，所述针头通过针头栓套装在所述注射器的乳头上，其特征在于：所述注射器的乳头内设有截止阀，所述截止阀由左半部与右半部构成，所述左半部设有凹槽，所述右半部设有与凹槽相配合的凸块，所述左半部与右半部上都设有防掉凸点，所述截止阀与乳头相交处 设有密封圈，所述注射器的外部设有外筒，所述注射器与外筒之间形成环形加压区，所述环形加压区内设有环形活塞杆，所述环形活塞杆的下端设有环形活塞，所述环形加压区的上方设有防掉环，所述注射器内设有主活塞杆，所述主活塞杆的下端设有主活塞，上端设有主活塞柄，所述主活塞柄的两侧又与环形活塞杆的上端相连接,所述外筒外侧的上方设有推拉环,所述环形活塞与环形加压区相配合。
与现有技术相比，本发明的有益效果是：本发明结构简单、成本较低、设计合理、操作便捷，能够暂时保存脑脊液，避免与空气接触，保护脑脊液的安全，可以防止不小心碰到推拉杆或误操作，将脑脊液推射出来；采用截止阀，能够在抽取完脑脊液后，关闭，防止脑脊液漏出，且采用的防掉凸点，可以避免截止阀脱落；采用的密封圈能够确保脑脊液不会泄露；采用的防掉环，能够确保环形活塞杆及主活塞杆不脱离于主体，而掉落外界。
附图说明
图1为本发明未抽取脑脊液时的结构示意图；
图2为图1中的A的放大示意图；
图3为本发明抽取脑脊液时的结构示意图。
