    摘要: A self-contained battery operated disposable blood pressure monitor having a semi-conductor transducer therein, the front side of which is intended to be fluid communication with an incompressible fluid in a intracorporeal catheter inserted in the heart of a patient for direct blood pressure monitoring. A calibration port vents the backside of the transducer to calibration and atmospheric pressures. The monitor contains circuitry electrically connected to the transducer which receives electrical signals output by the semi-conductor chip in response to the pressures exerted upon it through the pressure monitoring port. The circuity then electronically processes the signals so as to derive electronic data representing the mean arterial pressure pulse rate, and both systolic and diastolic blood pressures. The circuitry also analyzes the pressure wave forms of the pressure signals detected for poor signals so that it can present a visual diagnostic representative of the problematic pressure condition.
