Method of and device for causing blood coagulation
First Claim
1. A device for causing blood coagulation, particularly for use in endoscopy, comprisinga support having an end portion;
- an electrically operated thermo-element on said end portion;
current supplying means for supplying electrical current to said thermo-element to increasingly raise the temperature thereof in a predetermined gradient to a level at which it has a coagulation-causing temperature;
control means for maintaining said temperature steady when said level is reached;
visual indicating means for visually indicating the heating of said thermo-element to said level; and
audible indicating means responsive to the increasing heating of said thermo-element by producing a sound increasing in intensity in correspondence with the increasing heating gradient until said level is reached so as to indicate that the device is ready for use, and which thereafter continues at constant intensity.

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.

20. A method of operating a blood-coagulating device, particularly in endoscopy, comprising the steps of
electrically heating a thermo-element which is mounted on a support and is to supply heat to tissue when its temperature reaches a predetermined level; -
maintaining the heat of said thermo-element steady when said temperature level is reached; visually indicating the increasing heatingup of said thermo-element to said temperature level; and audibly indicating the increasing heatingup by generating a sound which increases in intensity until said temperature level is reached and thereafter remains steady as long as said temperature level remains steady. - View Dependent Claims (21, 22, 23)
