The new applied research on the multifunctional tubular pipeline in femoral artery and vein / 中国医学装备

ABSTRACT

Objective:To do research on designing the new applied multifunctional integrated tubular pipeline in femoral artery and vein which combined with blood transfusion, fluid infusion, blood sampling, administration, measurement of central venous pressure. Methods: Pipeline is consisted of three parts, which are blood transfusion part and fluid infusion part, including three way switch and three way extended tube. The first way connected with the injection is for blood sampling and doses, the second way connected with the central venous is for measurement of central venous pressure, and the third way connected with the blood transfusion set and fluid infusion set is for blood transfusion and fluid infusion. In a standard thoraco-abdominal combined injury and revivification of 31 beagle, compare the time effect. Results: In the injury and revivification test, the average time cost in 532 times nursing care operation with the multifunctional integrated tubular pipeline is 19+5.1 seconds, the average time cost in 31 times individual nursing care operation of 5 procedure is 80+12 seconds. The multifunctional integrated tubular pipeline can quickly and effectively work on blood transfusion, fluid infusion, blood sampling, administration, measurement of central venous pressure. Conclusion:The multifunctional integrated tubular pipeline in femoral artery and vein saves time and human resources and reduces the infection rate in repeated venous puncture and works quickly and conveniently on animal experiment and acute fatal injury, so it is worthy a further clinical application.
