Abstract

Urządzenie do wykrywania obecności krwi, przeznaczone do umieszczenia na odzieży, jest wyposażone w czujnik, zawierający podłoże (5) z materiału nieprzewodzącego, do którego są przymocowane dwie elektrody (6). Każda elektroda (6) posiada wyprowadzenie do zminiaturyzowanego układu rejestrującego, zawierającego układ do pomiaru rezystancji czujnika i zamiany wyniku pomiaru na wartość w funkcji tej rezystancji, z wyjściem którego jest połączone wejście układu porównującego do porównywania wartości w funkcji rezystancji czujnika z taką samą wartością w funkcji rezystancji granicznej między rezystancją podłoża (5) czujnika i rezystancją krwi, zaś wyjście układu porównującego jest złączone z wejściem nadajnika sygnału o stanie rezystancji czujnika.The device for detecting the presence of blood, intended to be placed on clothing, is equipped with a sensor, comprising a substrate (5) of non-conductive material to which two electrodes (6) are attached. Each electrode (6) has a lead to a miniaturized recording system, containing a system for measuring the sensor resistance and converting the measurement result into a value as a function of this resistance, with the output of which the input of the comparison system is connected to compare the value as a function of the sensor resistance with the same value as a function the limit resistance between the substrate resistance (5) of the sensor and the blood resistance, while the output of the comparison system is connected to the input of the signal transmitter with the sensor resistance state.
