Abstract
A method and a device for causing blood coagulation are disclosed. Both are especially well suited for use in endoscopy. A support is provided with an end portion on which an electrically operated thermo-element is located which receives electrical current to be heated to a level at which it has a coagulation-causing temperature. A control arrangement maintains the temperature steady when the level is reached. A visual indicator visually shows the heating of the thermo-element to the aforementioned level and an audible indicator audibly indicates the heating of the thermo-element by producing a sound which increases in intensity until the aforementioned temperature level is reached and which thereafter continues at a constant intensity while the temperature is maintained at the aforementioned level.
