Research on the influencing factors of infusion accuracy of disposable pump infusion set

When a medical infusion pump is used with a disposable pump infusion set for infusion, the change in infusion precision will affect the treatment effect, which will have a greater impact on burn patients and critically ill patients. Failure to infuse fluid in time will increase the mortality rate. Therefore, the factors influencing the infusion accuracy of disposable pump infusion sets under medium and high flow rate conditions are analyzed by conducting infusion experiments with flow rates of 100 ml/h, 200 ml/h, 500 ml/h and 1000 ml/h at temperatures of 10°C, 20°C and 30°C. The degree of correlation and influence between the infusion accuracy and the influencing factors are studied, and suggestions are provided. The results show that the grey correlation degrees between temperature, time and flow rate and infusion accuracy are all greater than 0.6, with obvious correlation. The correlation between temperature and infusion accuracy is the strongest. Temperature, time and flow rate all have significant effects on infusion accuracy and temperature has the greatest impact on infusion accuracy. When infusion is carried out under the condition of medium and high flow rate, the influence of temperature on the infusion accuracy should be considered first.
