SYSTEM FOR MONITORING THE BLOOD SUPPLY TO THE TRANSPLANTED ORGAN

Original language description

The system for monitoring the blood supply to a transplanted organ uses its spectral characteristics to monitor the organ’s status and, based on the evaluation of the measured results, it robustly classifies blood supply failure regardless of the local variability of blood perfusion. The proposed system is based on the measurement of slow changes in the intensity of the radiation reflected from the organ at several wavelengths in the visible and near-infrared spectral range. The state of the organ perfusion is evaluated on the basis of a common classification of slow changes and amplitudes of pulsations of the measured signals. The measurement accuracy is therefore not affected by the intensity of the perfusion, as is the case of pulse oximetry, but the pulse changes in the reflected light intensity can be evaluated. The modulation and demodulation technique applied to the measuring signals significantly increases the useful signal-to-noise ratio, thus allowing for a reduction in the overall system input power and increasing the distance between the sensors while maintaining high measurement accuracy. Due to this and due to the special mechanical concept of the sensor, the system allows to monitor a larger volume of tissue. The system also has low energy demands, making it suitable for battery operation. ### The patent is exploited by its owner.
