  • Publication number: 20150080819
    Abstract: The present invention is to provide a diaper structure, which includes a diaper main body formed by a fabric layer, an anti-leak layer and an absorbent material layer sequentially from the inner side to outer side thereof, and a communication chip and a metal antenna attached to the outer surface of the anti-leak layer and connected with each other to form an RFID tag. Thus, when the absorbent material layer absorbs the urine passing through the fabric layer and the inner surface of the anti-leak layer is in contact with the urine on the surface of the absorbent material layer, the change in the relative permittivity of the anti-leak layer causes a change in the impedance value of the metal antenna and consequently a change in the wavelength of the electromagnetic wave signal transmitted by the RFID tag, thereby enabling rapid detection of a soaking wet condition of the diaper.

  • Patent number: 8130094
    Abstract: In a mistake-proof monitoring method applied to a bedridden care system, the bedridden care system includes a computer, a plurality of transmitters and a warning device. The computer will generate a shutdown message to notice a nurse to check whether the transmitter is shut down maliciously, if no sensing message is transmitted from any transmitter within a predetermined time or a predetermined number of times. The computer will generate a detachment message to the warning device, if the transmitter is contacted improperly with a sensor. The computer will generate an error message to the warning device, if the time interval between the current time and a previous time occurring an abnormal situation is beyond a predetermined normal time interval and the sensor is not installed at a correct detected position. The mistake-proof monitoring method can immediately discover whether or not the sensors or the transmitters are operated at normal conditions.

  • Publication number: 20110319845
    Abstract: The present invention is to provide a diaper structure including two electrode strips, wherein the two electrode strips are disposed inside the diaper at a bottom position thereof and electrically connected to each other when both in contact with urine, and two metal button seats are disposed inside the diaper and are electrically connected to the two electrode strips respectively. Each of the two metal button seats has a first fastening portion disposed on the outside surface of the diaper and fastened with an electrical detection device, so that the two metal button seats are electrically connected to the electrical detection device via the two first fastening portions respectively for enabling the electrical detection device to send out a wetness signal when the two electrode strips are electrically connected to each other due to in contact with urine, thereby urging the caregiver to change the diaper structure immediately.
