である。2. Description of the Related Art In nursing homes and the like, diapers are used for cared persons such as dementia and highly disabled persons. The diaper change is preferably performed immediately each time there is incontinence (urination or defecation in the diaper). But,
In some cases, the cared person may not have the ability to complain of incontinence, or may refrain from complaining even though he / she has the ability. In practice, it is difficult to always change diapers in a timely manner.

られている。In order to solve such a problem, conventionally, two parallel electrodes are arranged inside the diaper so as to pass from the urination part of the diaper wearer to the defecation part, and a change in resistance between the two electrodes is detected. Thus, there is known an apparatus that detects incontinence.

むつセンサには次のような問題があった。The above-mentioned conventional diaper sensor has the following problems.

サ出力があっても、結局、おむつの隙間に手を入れるな
どしておむつの状態を確かめる必要があった。That is, the first problem is that a detection output is generated even when a small amount of urine is generated. A small amount of urine often leaks in elderly people and the like, and in such a case, it is not always necessary to change diapers immediately. However, the above-mentioned diaper sensor cannot distinguish between such a small amount of urination that does not require diaper replacement and the original urination that requires diaper replacement. It was necessary to check the state of the diaper by putting a hand in the gap.

る。[0006] The second problem is that it is not possible to distinguish between defecation and urination. Since the work performed by the caregiver is not the same for urination and defecation, the caregiver's position is to be able to recognize whether incontinence is urination or defecation when a sensor output is received. preferable. In order to distinguish between urination and defecation, it is conceivable to use the difference in resistance between the electrodes. However, this method has a problem that it is difficult to set the threshold value, and it is not always possible to make a reliable distinction. .

By making it a target, urination detection is not performed with a small amount of urination.

能とする。The conductive pattern has, for example, first and second strips connected to the first and second electrical connection terminals, respectively, and extending in the longitudinal direction of the equipment, and includes a second strip. A water-repellent layer is formed on the base material so as to cover both the strips except for the electrical connection terminals, with a cut in the middle portion, and the cut of the second strip is formed with respect to the water-repellent layer. A first window is provided on the periphery, and a second window is provided at a position separated in the longitudinal direction of the base material from the cut and extending across the first and second strips. Urine is allowed to enter.

And third and fourth windows are provided on the first and third strips around the position where the diaper wearer's stool is discharged in the longitudinal direction of the base material, respectively, without straddling other strips. ,
The first and third strips between the third and fourth windows allow the first and third electrical connection terminals to be in a conductive state by means of a flight extending between the strips.

On the other hand, the stool can continuously straddle between the third and fourth windows. Therefore, the first and third strips are conducted only by the flight. This makes it possible to distinguish and detect urination and defecation with a relatively simple configuration.

Thereby, the distance between the third and fourth windows can be set to a certain distance or more, and the occurrence of a state in which urine continuously straddles between both windows can be prevented.

信号が発せられる。FIG. 1 is a cross-sectional view of the waist of a diaper wearer, showing a use state of a paper diaper incorporating a diaper sensor according to the present invention. The sensor 20 is arranged inside the paper diaper 10 with respect to the waist 15. One end of the sensor 20 is connected to the detection circuit box 50 via the clip 49. The detection circuit box 50 is detachably adhered to the outer surface of the paper diaper 10 by an adhesive means such as a hook-and-loop fastener. From the detection circuit box 50, a signal is transmitted by a weak radio wave to the receiver 51 held by the caregiver or the like, indicating that urination or defecation has occurred.

The sensor 20 has detectors A and B that are separated in the sensor longitudinal direction for detecting urination. In addition, a detection unit C for detecting bowel movement is provided around the bowel movement unit Q.

る。As described above, the urination detecting sections A and B are separated from each other by a predetermined distance, and urination is detected only when urine is detected by both of the detecting sections. Does not generate a urination detection signal. If there is a bowel movement, a detection unit C dedicated to bowel movement detection
Generates a detection output. The defecation detection unit C is a urination detection unit A,
B is provided independently of B, and as described later,
Urination is not detected. Therefore, defecation and urination are detected separately. In addition, since the detection results of the urination detection units A and B are ANDed on the conductive pattern,
An AND circuit is unnecessary in the detection circuit (described later with reference to FIG. 4).

As the conductive ink or paste, a mixture of powder of a conductive substance such as silver or copper is used. The conductive pattern includes first, second, and third strips 22, 23, and 24 that are substantially parallel and extend in the longitudinal direction of the base 21. The second strip 23 has a cut 25 at its middle, where both sides of the second strip 23 are electrically insulated.

むつ用センサ２０自体はこの段階で完成する。Next, as shown in FIG. 2C, a water-repellent layer 29 made of water-repellent ink or the like is provided. At this time, the electrical connection terminal 31 at the end of the base material 21 and the window 33 around the cut 25
(Urination detection section A), and a window 36 extending between the first and second strips 22 and 23 of the urination detection section B near the right end of the base member 21 in the figure, and a third area around the defecation detection section C. The window 3 is placed on the first strip 22 and the third strip 24 so as not to span the other strips.
4, 35 are provided. Water is repelled by the water-repellent layer 29 other than these windows, and urine is prevented from spreading and floating on the surface. For this reason, there is almost no state in which urine continuously straddles between the window 34 and the window 35. On the other hand, there is no water-repellent layer in the windows 33 and 36, and the windows 33, 3 are smaller than the distance between the windows 34, 35.
6, the insulation distance between the conductors in the window 6 is small.
In each of 6, conduction by urine easily occurs.
In the case of a stool, regardless of the presence of the water repellent layer 29, the window 3
It is possible to easily and continuously straddle between 4, 35. The diaper sensor 20 itself is completed at this stage.

る。Although only the preferred embodiment of the present invention has been described above, various modifications and changes can be made without departing from the scope of the claims. For example, in the above-described embodiment, an example has been described in which the defecation / urination detection result is transmitted to the receiver side, but an alarm may be generated in the detection box without using such a transmission function.
Although the diaper sensor has been described as being built in the diaper, it can be used independently of the diaper.
