实用新型多功能股静脉置管管道装置的研制

目的：研究一种实用新型的集输血、输液、采血、给药以及中心静脉压测定为一体的多功能股静脉置管管道装置，完成临床多项护理操作。方法：将股静脉置管导管、输血器及输液器的部分原件，用3个三通及三通延长管进行组装。第1个三通连接输液器用以采血、给药；第2个三通连接中心静脉压导管用以测量中心静脉压；第3个三通连接输血器或输液器用以输血、输液。并将该管道装置应用于31只实验用比格犬重创胸腹联合伤的模型制作及复苏抢救，观察其时效性及实用性。结果：比格犬重创胸腹联合伤动物实验过程中的532次上述各类护理技术操作，平均每项（次）时间为（19±5．1）s；31次5项技术操作全程顺序进行，平均每次时间为（80±12）s。该装置实现了短时间内迅速开通输血、输液、采血、给药以及中心静脉压测定5项功能。结论：实用新型多功能管道装置具备快速、便捷以及同步进行多项护理技术操作的特点，节省了时间和人力，避免了静脉重复穿刺和感染，提高了工作效率，可广泛应用于动物实验、急危重症患者抢救及临床疾病的治疗，具有广阔的应用前景。

The new applied research on the multifunctional tubular pipeline in femoral artery and vein

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 552 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.
