Patent ID: 7503897

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; configured to determine the differential voltage of said excitation signal; and configured to determine the midpoint voltage of said excitation signal; at least one processor(s) configured to receive said measurement signal and said differential voltage and emulate an output signal indicative of the IBP of a subject according to predetermined instructions; an output configured to receive said midpoint voltage and configured to provide said output signal in a form suitable for input to an IBP monitor; and such that the midpoint of said output signal is substantially similar to that of said midpoint voltage; said processor(s) and output are configured to provide an output differential voltage in relation to said measurement signal in a form suitable for input to an IBP monitor; and said output is configured to add said midpoint voltage to the voltage at either terminal for said output differential voltage.
