Title: Temp. responsive sensor for live tissues - retains temp. stored in electronic evaluator, even after its removal from tested skin area, until comparison value has been quenched
Inventor: REEH JOHANN JOST DIPL ING DR
IPC: G01K7/24
Filed: 1979-08-04
Abstract: On the human skin surface there are zones connected to inner organs by so called skin segments. In addition temperature differences are of importance for acupuncture and electro-acupuncture. The sensor, used for temperature detection for these purposes, is fitted with an electronic evaluator, a measuring signal memory including tone evaluation, and a programmed print-out control. The sensor retains the temperature, stored in its electronic oart even after being removed from the skin area. This temperature retention is carried out by supply of intrinsic or external heat until the stored comparison value is quenched by pressing a measuring rod (3) against the skin. The quenching is carried out by a switch (5), which thus releases the recording and storage of the next temperature value. The sensor heating is preferably in a proportional ratio, either above or below of the previously stored temperature value.
