摘要: A device for simulating the pressure readings obtained from the arm of a living subject whose blood pressure levels are being determined by an oscillometric blood pressure monitor, includes a pulse pressure chamber for generating pressure pulses at a rate equivalent to a preselected pulse rate. The input to the pressure chamber is attached to the pressure cuff of the monitor and the output is connected to the pressure transducer of the monitor. In order to balance the pressure across the chamber and to apply the full cuff pressure to the monitor transducer, a normally-open valve is connected across the pressure chamber. This valve, however, is closed when the chamber creates a pressure pulse so that the pulse is added to the applied cuff pressure at the monitor transducer. A processor generates electrical signals that control the amplitude of the pressure pulses created by the chamber, depending on preselected values for simulated systolic, mean arterial and diastolic pressures.
