摘要： PURPOSE: To take an accurate and speedy diagnosis by converting the depth of a cecum into a signal output through a linear sliding type vaviable resistor.
CONSTITUTION: A probe 1 incorporates the linear sliding type variable resistor 11 applied with a constant voltage E and a voltage V having linear relation to the measured depth of the cecum is led out as the signal output. An arithmetic part 3 converts a digital signal from an A/D converter 2 into data for display, which is stored or outputted on a display part 6 by the operation of a foot switch 4 together with a tooth number. An output part 6 prints out the measurement result on a printer 7 or display it on a CRT display device 8. For this purpose, the tip of the probe 13 of a probe body 1 is inserted into the cecum until it abuts to the bottom part and a slider 15 is operated to bring the tip part of the probe 13 into contact with the edge of the gum. Thus, the resistance value corresponding to the length of the tip part of the probe 13 into the cecum, i.e. the depth of the cecum is obtained and lead out through a lead wire 19 as the signal output.
