特殊条件下静脉穿刺辅助装置的研制与临床应用效果

Development and clinical application effect of venipuncture auxiliary devices under special condi-tions

目的：设计研发一种在无光照或患者静脉条件较差的情况下也能清晰观察静脉走向的静脉穿刺辅助装置，并验证其临床效果。方法将79例休克患者按随机数字表法分为实验组（静脉穿刺辅助装置应用组，37例）和对照组（非装置组，42例），比较2组一次性穿刺成功率和所用时间。结果实验组和对照组一次性穿刺成功率分别为94.59%（35/37）、78.57%（33/42），建立单个静脉通路时间分别为（73.63±29.35）、（107.61±45.94）s，2组一次性穿刺成功率和建立单个静脉通路时间比较差异均有统计学意义，χ2=4.214，P<0.05；t=3.656，P<0.05。结论该装置是一种快速输液用探寻血管设备，可以辅助护士准确进行血管穿刺，使输液穿刺过程快速、顺利、有效。

Objective To design and develop a kind of venipuncture auxiliary device to use in the absence of light condition or patients with poor vein condition, and validate its clinical effect. Methods A total of 70 patients with shock were divided into experimental group (venipuncture auxiliary device group with 37 cases) and control group (non-device group with 42 cases) by random digits table method. The one-time puncture success rate and operating time were compared between two groups. Results The one-time puncture success rate was 94.59%(35/37) in experimental group and 78.57%(33/42) in control group, and there was significant difference, χ2=4.214, P<0.05. The time of establishing a single vein passage was (73.63±29.35) s in experimental group and (107.61±45.94) s in control group, and there was significant difference, t=3.656, P<0.05. Conclusions The device is small in size, low cost, easy to carry, the screen is clear, is a rapid infusion with explore vascular equipment. It can guide nurses accurately on vascular puncture, fast, smooth and effective transfusion puncture process.
