可叠放标本试管架的研制与应用

Development and application of foldable lest tube rack

目的研制新型可叠放标本试管架，解决集中送检标本时的不便及安全隐患。方法选择晨问集中收集、送检全院各科室尿标本69例次、482份，随机分为观察组和对照组。观察组使用可叠放标本试管架，对照组采用传统方法。结果标本放置稳定有效率，观察组为98．3％，对照组为95％；两组比较差异有统计学意义（x2=4．06，P〈0．05）；观察组未造成环境污染，对照组发生6次倾倒、溢洒，两组比较差异有统计学意义（x2=4．06，P〈0．05）。每次送检标本所需时间观察组平均为（18．72±2．92）min，对照组平均为（27．28±3．87）min，两组比较差异有统计学意义（t=3．04，P〈0．01）。结论应用可叠放标本试管架集中送检标本，具有省时省力，避免送检人员再次分拣及放置的优点，提高医务人员工作效率；使标本放置稳定，避免倾倒、溢洒造成环境污染。

Objective To develop a new foldable test tube rack to solve the inconvenience and safety issues arising from transferring the specimens to test all together. Methods 482 urine specimens of 69 daily routines collected in the morning from various sections of the hospital were randomly divided into experimental group and control group. The experimental group was placed in the foldable test tube rack; however, the control group was managed with traditional methods. Results The index of stability in the experimental group was 98.3%, 95.0% in the control group, and there was significant difference in both groups（x2 = 4.06,P 〈 0.05 ）. Environmental pollution did not occur in the experimental group, while it happened six times in the experimental group, there was significant difference between both groups （ X2 = 4.06, P 〈 0. 05 ）. The time for transferring specimens was （ 18.72 ± 2.92 ） minutes in the experimental group, （ 27.28 ± 3.87 ） minutes for the control group, there was significant difference between them （ t = 3.04, P 〈 0. 01 ）. Conclusions Foldable test tube rack for transferring specimen is time-saving, as well as avoids re-sorting and places specimens, improves work efficiency; enhances the specimen placement stability , avoiding environmental pollution arising from dumping, overflowing, and sprinkling.
