摘要

This engineering solution is concerned in a programmable invasive blood pressure simulator, fall into the technical field and biomedical engineering. The device is intended for the invasive blood pressure (IBP) simulation and its output parameters are suitable for patient's monitor testing and calibrating. Blood pressure (BP) is one of the principal vital signs. Blood pressure measuring can be provided by invasive or non-invasive methods. Invasive methods are based on invasive blood pressure (IBP) measurement through an arterial line. An arterial line is a thin cathether inserted into an artery. For measuring pressures in the hearth, we usually use a Schwanz-Ganz catheter placed into the pulmonary artery. Invasive arterial pressure measurement with intravascular cannulae involves direct measurement of arterial pressure. The cannula needle is placed in the artery (usually radial, femoral, dorsalis pedis or brachial). The cannula must be connected to a sterile, fluid-filled system, which is connected to an electronic pressure transducer. An output of the IBP transducer is get to the visualization system, usually patient's monitor with IBP module input channel. The measurement BP invasively through an arterial line is the most accurate method of BP measurement. This invasive technique is regularly employed in human intensive care medicine, anesthesiology, and for research purposes since the 1950s. Cannulation for invasive vascular pressure monitoring is infrequently associated with complications such as thrombosis, infection, and bleeding. Patients with invasive arterial monitoring require very close supervision. It is generally reserved for patients where rapid variations in arterial pressure are anticipated. The advantage of this system is that pressure is constantly monitored beat-by-beat and a waveform (a graph of pressure against time) can be displayed.
