ABSTRACT:
A device to stop bleeding of a part by supplying a heating current to and heating a heating element which is contained in the end part of a probe and whose voltage drop at its ends shows temperature dependency and by applying the end part to the bleeding part. The device includes a resistance installed in series with the heating element, compares the voltage of the resistance with a reference voltage, and controls the heating current value using the comparison output which depends on the temperature increase of the heating element, thus keeping the heating temperature at a temperature suitable for stanching.
