Since the sensor for a care device for detecting urination and defecation having the above structure can be formed in a tape shape, a lead cable from the care device is connected to the two electrode foils of the connecting portion to make a diaper or underwear. It can be easily inserted and attached to.

Then, the two strips of electrode foil separated and adhered to the lower surface of the tape-shaped surface material are water-absorbing tapes through an adhesive formed in a diagonal stripe shape having a width narrower than the width of the electrode foil. Since the strip-shaped backing material is adhered, the two sections of the electrode foil are in a non-conductive state in a dry and normal state, but when the care recipient urinates or defecates, the When the liquid is sucked into the back surface material and reaches between the two strips of the electrode foil from the striped portion without the adhesive in the diagonal striped pattern,
The space changes to a conductive state, and the connected care device can detect that the care receiver urinates or defecates.

Since the contact between the two electrode tapes of the member is released and the two electrode tapes return to the non-conductive state, the connected care device can know that the care receiver has left the bed.

The change between the contact state and the non-contact state between the conductive foil and the two electrode tapes causes the elasticity of the cushion member between the upper surface member and the lower surface member and the adhesion between the upper surface member and the lower surface member. The inflow and outflow of air from a plurality of air circulation holes provided in a non-bonded manner at a plurality of bent portions makes it possible to quietly and easily change the state and does not irritate the care recipient.

The upper member and the lower member can exhibit the above-mentioned effects regardless of which one of them is placed on the bed.

Further, since the edge portion and the end portion of the upper surface member and the lower surface member are bent and adhered, even if the care receiver or the caregiver touches the edge portion or the end portion, the skin is not damaged. .

The two strips of electrode tape that were in contact with each other and separated and adhered to each other and were in a non-conductive state between each other are in a conductive state, and the connected care device can detect that the care receiver is in the bed.

When the cared person is separated from the bed, the pressure on the upper surface member is released, and the contact between the conductive foil adhered to the lower surface of the upper surface member and the two electrode tapes on the lower surface member is separated. Since the non-conductive state is restored between the electrode strips of the strip, the connected care device can detect that the care receiver has left the bed.

The change between the contact state and the non-contact state between the conductive foil and the two electrode tapes causes the elasticity of the cushion member between the upper surface member and the lower surface member and the adhesion between the upper surface member and the lower surface member. The inflow and outflow of air from a plurality of air circulation holes provided at a plurality of bent portions in a non-adhesive manner allows quiet and easy state changes, and does not irritate non-nurses.
