めに皮膚の表面に電極を密着しなければならない。It is induced by the activities of the brain, muscles, etc. ! Samurai's bioelectricity of the heart uses an external electrocardiograph to detect weak currents induced on the skin of a living body to diagnose heart abnormalities. This electrocardiograph requires electrodes to be brought into close contact with the surface of the skin in order to electrically connect the input section to the living body.

When the electrode cup 2 is brought into contact with the top and the pressing force of this hand is released, the pressure inside the electrode cup 2 is reduced by the elastic restoring force of the rubber dropper 1, and the rubber suction electrode 1 is attracted to the skin surface. I try to let them do it.

0 and is vigorously sprayed from the spray nozzle 31 whose tip is constricted. When this pressurized air is injected, as shown in FIG. The pressurized air is also discharged to the outside of the suction cup 19. When the air inside the opening 24 is discharged, the opening 1] inside the opening 24 (negative pressure phenomenon suddenly occurs), and as a result, the suction cup 19
The skin surface connected to the contact piece 23 is sucked upward, the skin surface is attracted by the contact piece 23, and the suction type induction electrode 18 is brought into close contact with the skin surface. After the cardiac examination is completed in this way, if the operation of the pressurizing pump is stopped, the suction cup-type induction electrode 18 (!: The suction on the skin will be easily released) 4. "Effects of the present invention" According to the present invention, pressurized air is introduced into the suction type induction electrode to generate a negative king phenomenon between the skin surface of the living body and the suction type induction electrode, thereby attaching the suction type induction electrode to the skin surface. Since it is made to be adsorbed, there is no need to press the adsorption electrode against the skin surface to adsorb it, unlike conventional rubber adsorption electrodes, and as a result, you will not feel any pain, and even people with sensitive skin will be able to avoid inflammation. Nothing will happen.
