Analysis of Rise Time Responses of a Smart Infusion Pump for the Control of Dopamine Drug Flow Rate

Abstract

The smart infusion pumps are prominently used to administer drug effectively for the patient. The usage is increased, as the patient safety is critical, and the reduction of medication errors are necessary. The control of drug flow rate in infusion pumps are crucial as it can have substantial impact on patient safety. The implementation of control system model and tuning of the related control parameters are desired. In this paper, an attempt has been made to analyze the rise time (RT) responses of a representative smart infusion pump. The syringe and volumetric administration of Dopamine drug are considered for this study. The examination of the desired target flow rate is accomplished by using different control tuning schemes such as Proportional Integral Derivative (PID) and Internal Mode Controller (IMC). The evaluation of the control strategy is demonstrated with parameters such as RT and settling time (ST). Results show that it is possible to achieve desired RT for the considered infusion conditions by tuning both PID and IMC. The values of RT obtained are 0.215 and 0.383 s respectively. Further, as it is often important to tune RT for patient specific Dopamine administration, the study seems to be relevant for the design of automated drug infusion systems.
