微量泵是用少量液体将药物精确、微量、均匀、持续地泵入体内,其流速稳定、定时、精确度高,不会因患者体位变化而影响输注速度,既能定时控制药物总量,又可保证药物的最佳血药浓度,充分体现持续恒定的治疗效果,避免因药物浓度改变而影响疗效或发生不良反应[1]。脑血管病患者由于 Micro-pump is a small amount of liquid drugs will be accurate, trace, even and continuously pumped into the body, the flow rate stability, timing, high accuracy, will not affect the patient’s position changes infusion speed, both regular control of the total amount of drugs, But also to ensure the best blood drug concentration, and fully reflect the sustained and constant therapeutic effect, to avoid changes in drug concentration affect the efficacy or adverse reactions [1].
