Abstract
A blood component monitoring system for monitoring chemical substances of interest in blood, which includes a transfusion circuit including a flow-through cell adapted to be fluid-connected with a blood vessel through an indwelling catheter, a reservoir for accommodating a quantity of physiologically compatible sensor correcting solution, a connecting tubing extending between the reservoir and the flow-through cell and a transfusion pump; a detector unit including a temperature sensor and a chemical sensitive sensor device both incorporated inside the flow-through cell. A transfusion pump drive circuit is provided for controlling operation of the transfusion pump, a sensor drive circuit is provided for driving the temperature sensor and the chemical sensitive sensor device, a processing unit is provided for controlling both of the transfusion pump drive circuit and the sensor drive circuit and for reading respective outputs from the temperature sensor and the chemical sensitive sensor device and converting the outputs into respective measured values, and an output device is provided for externally outputting the measured values.
