る。Means for Solving the Problems [Claim 1] When the water of the excrement absorbed by the excrement absorbing portion reaches the vicinity of the excrement absorbing portion, the excrement of the diaper is provided with a water transmission band for transmitting the moisture. It is located in the surrounding area. Then, at least one pair of conductor detection units whose electrical characteristics change when the moisture transmission band corresponding to the detection unit gets wet faces the right part of the moisture transmission band.

することができる。When the accumulated amount of excrement absorbed in the excrement absorbing portion increases and the water in the excrement reaches the moisture transmitting band arranged around the excrement absorbing portion, the water in the excrement absorbing portion is moved by the capillary phenomenon. It reaches the right place where the detection unit faces. As a result, the electrical characteristics (resistance value, capacitor, impedance, resonance frequency, etc.) of the conductor change. By exchanging the diaper after detecting the change in the electrical characteristics of the conductor, it is possible to prevent lateral leakage in which excrement overflows from the side of the diaper. Since the detection unit does not get wet with a small amount of excrement, the electrical characteristics of the conductor do not change, and excessive diaper replacement can be prevented.

係わらず、所定量以上の排泄物の蓄積を検知できる。[0008] [Claims 2 and 5] A water transmission band is arranged so as to surround the excrement absorption unit, and the detection unit faces at least a part of the water transmission band. When the accumulated amount of the excrement absorbed in the excrement absorbing portion increases, the water in the excrement reaches the water transfer zone surrounding the excrement absorbing portion. Then, the electric wave travels through the moisture transmission zone due to the capillary phenomenon and reaches the moisture transmission zone facing the detection unit, so that the electrical characteristics (resistance value, capacitor, impedance, resonance frequency, etc.) of the conductor change. In this way, by disposing the moisture transmission band so as to surround the excrement absorbing portion, it is possible to detect the accumulation of excrement of a predetermined amount or more regardless of the flow direction of the water in the excrement.

確に報知することができる。[Claims 3 and 6] By waterproofing the portions other than the detecting portion of the conductor, the electrical characteristics of the conductor change only in accordance with the wetting of the moisture transfer zone. Thus, a small amount of excrement is not notified, and the diaper replacement time can be accurately notified.

To reach the right place where the detection unit faces. As a result, the electrical characteristics (resistance value, capacitor, impedance, resonance frequency, etc.) of the conductor change, the transmitter transmits a signal, the signal is input to the alarm, and the alarm notifies.

が良い。[0011] By replacing the diaper by the monitor based on the notification, it is possible to prevent lateral leakage of excrement from overflowing from the side of the diaper. In addition, since the detection unit does not get wet with a small amount of excrement, no notification is made, and excessive diaper replacement can be prevented. With a configuration in which the signal of the transmitter is wirelessly transmitted to the alarm, the observer can monitor the presence or absence of excretion away from the wearer of the diaper, which is convenient.
