内容記述 | During the left ventricular bypass, it is important to keep the arterial and atrial pressures at a physiological level to maintain the circulation and at the same time to rest the failing heart (recovery of the failing heart). We have developed a microcomputer based control system for the left ventricular assist pump (LVAP). The control system regulates the arterial and atrial pressures at a physiological level by adjusting the cardiac output of the LVAP. The superior feature of the control system is that it has an indirect measuring system. The arterial and atrial pressures are observed from the careful analysis of pressure in the LVAP air chamber. The assist air pressure shows that the air pressure at the specific momentary points when a diaphragm begins to move reflects the pressure in proportion to the arterial or atrial pressure. The specific momentary points are monitored by an optical diaphragm position sensor when a diaphragm begins to move at a systolic or diastolic period of LVAP, and the pressures at those points are measured by means of a drive air pressure transducer. A microcomputer obtains the indirectly measured arterial and atrial pressures through the A/D converters. The control system regulates the cardiac output of LVAP by adjusting the driving conditions (driving pressure, vacuum pressure, ejection duration, and driving rate) according to the indirectly monitored parameters. The control system consists of an optical diaphragm position sensor, pulse motor driven pressure regulators, a drive air pressure transducer, and a microcomputer. As a result of in vitro experiments, the control system regulated the arterial and atrial pressures smoothly at a desired level. | |||||
