利用一次性便携式输注泵可变参数模拟流速限制器开关的创新和临床应用

Innovation and Clinical Application of a Flow-Limber Switch Simulation Using Variable Parameters of a Disposable Portable Infusion Pump

摘要: 目的：调整一次性使用便携式输注泵(百特泵)的两个可变参数，即流速限制器温度和弹力贮液囊高度差，保证化疗液体泵注时间。方法：将79例患者，共接受百特泵持续化疗120例次，按其化疗先后顺序，依次分成观察组和对照组，每组60例次患者。对照组将百特泵流速限制器贴近皮肤，弹力贮液囊与流速限制器在同一高度。观察组将百特泵流速限制器置于室温26℃，弹力储液囊与流速限制器在同一高度。结果：观察组的60例患者中，流速在正常范围内(65.5~80 h) 58例次，流速过快2例次，误差率3.3%。对照组的60例患者中，流速在正常范围内(65.5~80 h) 51例次，流速过快6例次，流速过慢3例次，误差率15.0% (P < 0.05，差异有统计学意义)。结论：建议护士根据可变参数如灌注量、稀释液种类、温度等的实际情况，计算化疗方案对流速的影响结果，使便携式输注泵保持标准流速泵入。

Abstract: The two variable parameters of Baxter pump, namely the temperature of the flow rate limber and the height of the elastic reservoir, are adjusted to ensure the pumping time of chemotherapy liquid. Methods: A total of 79 patients received 120 cases of chemotherapy with Baxter pump. According to the order of chemotherapy, they were divided into observation group and control group, 60 cases in each group. In the control group, the flow rate limiter of Baxter pump was close to the skin, and the elastic reservoir was at the same height as the flow rate limiter. In the observation group, the flow rate limiter of Baxter pump was placed at 26˚C, and the elastic reservoir was at the same height as the flow rate limiter. Results: In the observation group, the flow rate was within the normal range (65.5~80 h) in 58 cases, and the flow rate was too fast in 2 cases, with an error rate of 3.3%. Howev-er, in the control group, the flow rate was within the normal range (65.5~80 h) in 51 cases, too fast in 6 cases, and too slow in 3 cases, with an error rate of 15.0% (P < 0.05, the difference was statisti-cally significant). Conclusion: It is recommended that nurses reflect on the effect of chemotherapy regimen on flow rate according to the actual situation of variable parameters such as perfusion volume, diluent type, temperature, etc., so that the portable infusion pump can maintain the standard flow rate.
