Estimating the term…
A stimulation device for the determination of the temperature perception of the skin of a patient by means of a stimulator, which is arranged in a casing and which can be heated up or cooled down by a Peltier element. The stimulator (1) is arranged moveably along an axis (5) in the casing (4) and shows a projection (14) in relation to the casing (4) in the starting position. A first pressure device (6) cooperates with said stimulator (1) in such a way that said stimulator (1) can be shifted along said axis (5) by expenditure of force until said projection (14) is at zero. The force is predefined or adjustable by said first pressure device (6).
A stimulation device for the determination of the temperature perception and pain sensation of a patient by cutaneous contact stimulation comprising a casing including a bearing surface for engaging the skin of the patient, a stimulator received in said casing adjacent the bearing surface of said casing and a Peltier element for changing the temperature of said stimulator, characterized in that the stimulator (1) is arranged moveably along an axis (5) in the casing (4), a first pressure means (6) for biasing with a force of a predetermined magnitude said stimulator toward a starting position in which the stimulator protudes a predetermined distance (14) from said casing beyond said bearing surface (15), and a second pressure means (21) for supporting said casing and biasing the bearing surface of said casing toward the skin of the patient with force sufficient to retract said stimulator by moving said stimulator in a direction toward into said casing to a position in which the protruding portion of said stimulator becomes substantially coextensive with said bearing surface.
