Abstract: An oximeter probe to be wound on a fingertip of an object and used to measure the oxygen saturation of blood is completely shielded from electrical noises. The front face of an a flexible printed circuit board on which an a light-emitting device and a photodetective are mounted is covered by a conductive sheet having windows at the locations which correspond to the LED and the photodetector. The back face of the circuit board is covered by shield copper foil.

Abstract: An object of the present invention is to prevent "low-temperature burn" that occurs on account of heat generation by the LED in an oximeter probe. The oximeter probe comprises adhesive tape which has an opening formed at the site where the LED is fitted, and a heat-dissipating plate is provided in the opening.

Abstract: Disclosure is a bio-electrode which can prevent paste from oozing out and color change from occurring and which allows the measurement to be stably performed even at the time immediately after the application. A catalyst is injected into sponge in a foam tape and then a monomer is injected into the sponge. Thereafter, paste is injected into a center portion of a surface of the sponge which is in the side opposite to an electrode element.

Abstract: A non-invasive automatic blood pressure measuring apparatus consisting of a blood flow meter non-invasively detecting the blood flow of the arteries on the proximal or distal side of the cuff, a blood flow standing up point detecting means detecting the standing up point of the blood flow signal output from the blood flow meter in the decompression process of the internal pressure in the cuff and a blood flow returning point detecting means detecting the returning point of the blood flow signal to the steady state in the further successive decompression process, and detecting the internal pressure in the cuff of the standing up point as the maximal value of the blood pressure and the internal pressure in the cuff of the returning point as the minimal value of the blood pressure.
