Patent ID: 7144372

Claim:
An interface configured to connect between a noninvasive blood pressure (NIBP) sensor and an invasive blood pressure (IBP) monitor comprising a first input configured to receive a measurement signal indicative of the NIBP of a subject; a second input configured to receive a transducer excitation signal provided by an IBP monitor; at least one processor(s) configured to receive said measurement signal and said excitation signal and emulate an output signal indicative of the IBP of a subject according to predetermined instructions; and where the differential voltage of said output signal depends on said excitation signal, a predetennined or selectable transducer sensitivity, and said measurement signal; and an output configured to provide said output signal in a form suitable for input to said IBP monitors, including a digital-to-analog converter (DAC) to receive output signal from said processor(s), and said DAC is configured according to predetermined instructions such that its full-scale output voltage range includes the voltage range corresponding to a predetermined maximum pressure range of the NIBP of a subject.
