Objective To explore the application of portable infusion pump on patients with angina.Methods Sixty cases patients with angina were randomly divided intoexperimental group who were used infusion pumps and control group who received manual speed control.Results The experimental group was significantly better than the manual speed control group in terms of infusion speed coincidence,rate of the patient's comfort and nursing satisfaction rate.Conclusions The liquid velocity using continuous infusion pump input was more Precision.Rate of the patient's comfort and nursing satisfaction rate are higher,it also Improves the efficiency of the nurses,reduces the labor intensity of nurses and improves the effect of clinical treatment.
