Theory

Invasive Blood Pressure Block Diagram

Patient blood pressure detection is by pressure transducer connected to the patient blood vessel via

catheter or tubing.

A +5v excitation voltage is applied to the pressure transducer. The output of the pressure

transducer is at 5uv/mmHg/V.

Blood pressure signal is converted to voltage by the pressure transducer and sent through the filter

to the amplifier.

Calibration signal is control by a multiplexer for calibrating BP1 and BP2 channels.

Amplified signal is sent to the analog to digital converter for conversion.

Digitized signal is sent to the microcontroller for processing.

Temperature Block Diagram

Patient temperature detection is by using a temperature probe. The thermistor inside the

temperature probes varies according to the temperature changes.

The thermistor signal is sent through a filter to the amplifier. Then sent to the A/D for

conversion. Digitized signal is sent to the microcontroller for processing.

A 20°c and 40°c signal controlled by the ATMEGA162V is used for auto calibration of the

temperature channels.
