一种新型桡动脉穿刺固定装置的研制

Development of new radial artery puncture and fixation device

目的:针对传统桡动脉穿刺固定的缺点,研制一种新型桡动脉穿刺固定装置。方法 :该装置主要由臂托部、手托部、手腕部、手臂固定带、手掌固定带和止血带组成。臂托部为凹面结构,其和手托部相交的部分为手腕部,手腕部设有凸起垫块,凸起垫块内部有充气式气囊,充气式气囊通过充气管与充气球连接,充气球与充气管连接处有气阀。固定带一端分别与臂托部、手托部和手腕部固定连接,另一端通过魔术贴与臂托部、手托部和手腕部的另一侧相连。止血带内表面固定设置一个压迫式止血气囊。结果:使用该装置有助于缩短穿刺时间,提高穿刺成功率,减少动脉针拔除后出现渗血、血肿的例数,提高医患满意度。结论:该装置结构简单、使用方便、实用性强、安全性高,达到设计目的。

Objective To develop a new radial artery puncture fixing device to conquer the deficiencies of traditional method. Methods The device was composed of an arm support,a hand support,a wrist part,an arm fixing belt,a palm fixing belt and a tourniquet.The arm support was concave-shaped,and was connected with the hand support with the wrist part.The wrist part had a raised block which was gifted with an inflatable bag.The balloon linked with an inflation balloon with an inflation tube.There was a valve between the inflation tube and balloon.The fixing belt had one end directly connected with the arm support, hand support and wrist part, and the other end linked with the other ends of the above components with Velcro. There was a compression hemostatic balloon at the internal surface of the tourniquet. Results The device behaved well in puncture time and success rate,and decreased the incidence rates of errhysis and hematoma after withdrawing the puncture needle while increased the satisfaction of medical staffs and patients. Conclusion The device gains advantages in simple structure,convenience,practicability and safety,and meets the desired requirements.
