摘　　要：目的观察3种微量注射泵应用过程中泵体垂直移动前后短时间内流出量的变化。方法分别用电子天平定量测定国产、日本产、德国产3种微量泵在停机STOP状态下垂直移动泵体后和10ml/h的工作状态下垂直移动泵体前及移动后1min的流出量,重复测定10次。结果3种注射泵在STOP状态下移动后1min的流出量分别为(0.7411±0.0667)ml、(0.2909±0.0417)ml、(0.6021±0.0147)ml,经两两比较,差异有显著性意义(均P<0.01)。3个注射泵在10ml/h的工作状态下,移动前1min泵体实际流出量分别为(0.1657±0.0049)ml、(0.1803±0.0037)ml、(0.1743±0.0009)ml,移动后1min的流出量分别为(0.9423±0.0285)ml、(0.4565±0.0204)ml、(0.7789±0.0179)ml,与移动前1min的流出量比较,差异有显著性意义(均P<0.01)。结论连接延长管的注射泵在STOP及运行状态下垂直移动泵体后短时间内有一定量的液体流出,应用微量注射泵过程中应尽量避免移动或关闭延长管后移动,以避免意外输入液体造成的危害。Objective To observe the outflow of miero-injection pump before and after vertieal movement during use. Methods Three micro-infusion pumps, made in China, Japan and Germany, respectively, were examined. The outflow in 1 min was collected and weighed with an electronic balance after the passive vertical movement of the pump at the STOP status and at the flow-rate of 10 ml/h. The measurements were repeated 10 times. Results The outflow at the STOP status was （0. 7411±0. 0667） ml/min, （0. 2909±0. 0417） ml/min and （0. 6021±0. 0147） ml/min, respectively. Paired comparison showed significant difference in the outflow among the 3 pumps （P〈0.01 for all）. At the flowrate of 10 ml/h, the outflow before the movement was （0. 1657±0. 0049） ml, （0. 1803±0. 0037） ml and （0. 1743± 0. 0009） ml, respectively and the outflow after the movement was （0. 9423±0. 0285） ml, （0. 4565±0. 0204） ml and （0. 7789±0. 0179） ml, respectively. The differences in the outflow of each pump during 1 min before and after the movement was significant （P〈0.01 for all）. Conclusion The micro-infusion pumps, after connection of extension tube, have some liquid outflow in a short time before and after passive pump movement. Care should be taken to avoid moving the pump during infusion or to move after clamping the extension tube so as to avoid accidental infution.
