微量注射泵具有能将药液精确、微量、恒量、恒速、持续泵入人体内的特点[1]。在心血管内科病区,大部分为心力衰竭患者,心力衰竭患者病情多变且常伴有血压、呼吸、心率、心律不稳定及相关重要脏器的衰竭,需微量注射泵泵入各类血管活性药物、强心药物、抗心律失常药物、镇静药物、降压药物及电解质溶液等需严格控制流速、流量的药物。由于上述药物的特殊性,微小剂量的改变都会使患者的心率、血压等发生变化。使用微量注射泵也存在一些如操作程序不够熟练、脱管、仪器中断 Micro syringe pump can be accurate, trace, constant, constant speed, continuous pumping into the body’s characteristics [1]. In the cardiovascular medical ward, the majority of patients with heart failure, heart failure patients with varying conditions and often accompanied by blood pressure, respiration, heart rate, cardiac arrhythmias and related vital organs of the failure to be micro-injection pump into various types of vasoactive Drugs, cardiac drugs, anti-arrhythmic drugs, sedatives, antihypertensive drugs and electrolyte solutions, such as the need to strictly control the flow rate, flow of drugs. Due to the special nature of these drugs, small changes in the dose will make the patient’s heart rate, blood pressure and other changes. The use of micro-syringe pump there are some such as the operating procedures are not proficient, off the tube, the instrument interrupt
