目的:观察一次性真空采血器加压技术在临床采血中的应用价值。方法:将采血人群随机分观察组和对照组每组100人,其中观察组在采血过程中使用一次性5mL注射器加压方法改进采血的技术,对照组采血时使用一次性采血针及负压真空管常规方法进行,观察比较两组体检人群采血时的一次抽血成功率。结果:观察组体检人群一次抽血成功为95人,合格率为95.0%,而对照组采用常规采血方法后,一次采血成功为60人,合格率为60%。观察组采血成功率明显高于对照组(P<0.05),差异有统计学意义。结论:使用加压方法改进采血技术后,解决真空采血器负压不够的问题,缩短了采血时间、增加了采血量、保证采血样本质量,提高了临床采血的成功率。
Objective: To observe the value of disposable vacuum blood collection device in clinical blood sampling. Methods: The blood sampling population was randomly divided into observation group (100 cases) and control group (100 cases). In the observation group, a one-time 5 ml syringe was used to improve the blood sampling technique. In the control group, disposable blood collection needle and negative pressure vacuum tube Conventional methods were observed and compared two groups of medical examination blood sampling success rate of a blood draw. Results: In the observation group, there were 95 successful blood tests at a time, with a pass rate of 95.0%. In the control group, 60 blood samples were successfully collected after a routine blood sampling procedure, with a pass rate of 60%. The success rate of blood sampling in observation group was significantly higher than that in control group (P <0.05), the difference was statistically significant. Conclusion: The improvement of blood sampling technique using pressurized method solves the problem of inadequate negative pressure of vacuum blood collection device, shortens the time of collecting blood, increases the volume of blood collection, ensures the quality of blood sampling and improves the success rate of clinical blood sampling.
