Invasive blood pressure curves simulation device

Abstract

Patient monitor modules have various inputs for vital function measurement. We can practice many of these measurements with some students in the laboratory of biomedical engineering. However, invasive blood pressure (IBP) measurement demonstration is impossible. This paper is dealing with design and realization of a programmable invasive blood pressure simulator. This device is able to generate programmable behavior of voltage signal with correspond to blood pressure curve. The user communication interface of the device allows choosing the type of generated signal by LCD and 4 push buttons. The wide spectrums of generated signals, which correspond to physiological or pathological blood pressure curves, are stored in a user programmable memory. The output connectors of the device can be directly connected to a patient monitor IBP module input. Invasive blood pressure measurement simulation for educational purposes and calibrating the patients monitors are the general usages of the developed device.
