PERFUSION PUMP: MATHEMATICAL MODELING USING BOND GRAPH FOR BLOOD PRESSURE CONTROL

Abstract

Intravenous administration of medicines is usually performed using a perfusion pump. However, there are still reports of accidents associated with this technology. This article presents a Mathematical Modeling proposal based on the Bond Graph technique in order to simulate a Continuous Perfusion Pump. Presenting a mathematical model for the medicine perfusion procedure to control the mean blood pressure (MBP) is essential for the effectiveness of the treatment, which must follow a linear pattern and with a small regimen error. To this end, modern dynamic control techniques are used to know the mechanical parameters for the analysis of pressure data and to control the process through an electronically controlled pressure pump. This study has the goal of identifying the mathematical model of the pump perfusion procedure and presenting a fuzzy controller. The contribution of this study was to present the mathematical model with refinements based on prior knowledge of the phenomena involved and an analysis of dynamic control of the mathematical model with the use of fuzzy control.
