Software Control There are no software requirements on this board. The microcontroller for this board’s functions are located on the LED/CPU board. Hardware Functions Pressure transducer circuitry A pressure transducer and amplifier is provided to acquire the cuff pressure signal. Performance is consistent with pressure range and accuracy specifications for the NIBP module. Over pressure transducer circuitry An over pressure transducer, independent of the main pressure transducer is provided. An amplifier, a comparator with three selectable over pressure limits, and an over pressure output signal interpret the transducer state. Over pressure limits are set according to the patient size. Five A/D channels All channels are at 12 bit resolution and digitized at 300 Hz: 1) DC pressure 2) AC pressure (pulse) 3) Hardware over pressure transducer 4) Hardware over pressure comparator reference. 5) Battery voltage monitoring, when the Accutorr is in battery operation. Pulse Channel Filter A high-pass filter is provided to isolate the pulsatile component from the DC cuff pressure. This pulsatile component is digitized as the pulse channel. The gain of this AC coupled channel is programmable in a manner consistent with the specified range of pulse amplitudes. Means are provided to rapidly “reset” the filter following disturbances caused by motion or activation of the pump or valves. Inflation Pump A pump capable of inflating the cuff within the specified time limit. Bleed Valve A valve and control system capable of bleeding down the cuff pressure in accordance with the specifications. Dump Valve A valve to rapidly discharge the residual cuff pressure at the end of the measurement cycle. 2-18 Revised 12/20/00 Accutorr Plus Service Manual Chapter 2 - Theory of Operation
