Abstract

<P>PROBLEM TO BE SOLVED: To provide a diaper sensing that the diaper of the wearer of the diaper such as the old or a patient is wet by a sensor to accurately and quickly inform a care giver. <P>SOLUTION: The diaper has a first signal means signaling or a second signal means for signaling by sound due to an electroconductive state electrode plates when the diaper gets wet by blinking of light by fitting one or more of the planar electrode plate(s) to the tips of wires and by pressing and contacting them to the location of the diaper where the diaper gets wet, and a third signal means for transmitting regenerated sound via FM radio waves by a shifting switch and signaling by receiving the regenerated sound by a remote FM radio receiver. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a diaper wetness notification device that allows a diaper wearer to attach a sensor equipped with an electrode so that when a diaper gets wet with urination, the diaper wetness notification can be made immediately.

  In order to check whether a diaper is wet, conventionally, a hand is put in the diaper and the wet part is touched.

  Even if the diaper was wet, if the party did not signal or could not signal, the third party could not know about it.

For example, in Japanese Patent Laid-Open No. 2002-301098, a sensor is attached to the diaper itself. However, the processing and the apparatus are large, and it is difficult to check the cost easily and easily.

If left in a wet diaper for a long time, the wearer is forced to feel uncomfortable and cause infection. Also, when it was cold, it could cause the body to cool and catch a cold.
Further, it is troublesome and unsanitary, such as detaching clothes, to examine whether a diaper is wet by hand, and there is also a risk of nosocomial infection in some hospitals and other facilities.
The present invention is intended to solve such a problem, and by signaling that the diaper is wet by a sensor, the caregiver can accurately and hygienically determine and respond immediately. I can do it. The party can promptly change wet diapers, which can reduce unpleasant feelings.

One or two or three sensors equipped with electrode plates at the end of the cord are placed in the diaper on the front side of the urinary tract or in a state of sandwiching them, and when the sensor gets wet appropriately, a signal is flashed by light. The first cue means and / or the second cue means for signaling by sound, and the change-over switch transmits the recorded sound on the FM radio wave, and the sound can be heard by other remote FM radio receivers. It is set as the structure provided with the trip signal means.
At this time, the signal to be signaled is that the diaper wearer can record the desired voice or music for about 20 seconds, and the frequency of the FM radio receiver is a 76 MHz to 81 MHz broadcast frequency band. It can be set to a desired frequency other than the broadcast frequency band.

According to the present invention, by appropriately bringing the sensor into contact with the diaper, it is possible to check that the diaper is wet hygienically and accurately without soiling the hand. That is, when it is not desired to make a sound at night, it can be signaled that the diaper is wet by blinking the LED. Also, in combination with this, the voice can be reported by reproducing the voice recorded in advance by the wearer or by generating a sound agreed with the wearer. In the present invention, even if the diaper is in a wet state, the generated sound can be received via the FM radio receiver, and the countermeasure can be immediately taken. be able to.
The invention according to claim 2 is particularly effective in enabling close-care care when reproducing the voice of the wearer.
According to the invention described in claim 3, by changing the reception frequency, it is possible to avoid interference with the frequency used by other electronic devices.

  FIG. 1 is a flow sheet diagram showing an embodiment of the device of the present invention, and FIG. 2 is a circuit diagram of a notification device. 3 is a plan view of an electrode plate according to the sensor, and FIG. 4 is a signal processing circuit diagram.

  1 is a sensor provided with flat electrodes 1a and 1b having a vertical and horizontal dimension of about 35 mm, and 2 is a cord thereof depending on whether the diaper wearer is sleeping or waking up. Means are employed that allow the length dimension to be adjusted as appropriate. In the apparatus of the present invention, the other devices except for the sensor 1 are stored in one housing 3. According to the prototype of the present inventor, the vertical, horizontal, and height are approximately 2 cm × 5 cm × The size of the pocket storage size is about 12 cm.

  That is, the housing 3 includes a power source and a power circuit (three-terminal regulator) 4, a signal processing circuit 5 from the sensor, an LED display device 6 thereby, the voice recorder device 7 and a speaker 8, and FM radio wave transmission. The circuit 9 and the like are incorporated. In the description of the present example, the sensor 1 is illustrated for one use, but a plurality of uses such as two or three can be used. In the drawing, 10 is an on / off switch, and 11 and 12 are changeover switches.

Next, the operation will be described. In the present invention, when the sensor 1 is brought into contact with the diaper, the sensor 1 is attached in front of the urine and / or in a state of sandwiching the urine. At this time, in order to prevent the contacted sensor from moving, it is temporarily fixed with an adhesive tape.
Thus, the switch 10 of the power supply circuit 4 is turned on. When the diaper gets wet, the electrode plate of the sensor 1 is short-circuited, and the signal is sent to the signal processing circuit 5. Notification of the first signal means that blinks and signals

On the other hand, if the switch 10 is turned on and the changeover switch 11 is on the speaker 8 side, the sound recorded in the voice recorder 7 is reproduced and flows from the speaker 8, and a notification is made as a second signal means. Become.
On the other hand, if the change-over switch 11 is turned on and the change-over switch 12 is on the FM radio wave transmission circuit side, the recorded sound is transmitted on the FM radio wave and reproduced from an FM radio receiver in another remote location. A notification is made as a third signaling means for signaling by sound. At this time, the frequency of the FM radio receiver is set to a desired frequency other than the radio broadcast reception frequency band in the broadcast frequency band of 76 MHz to 81 MHz.

According to the present invention, it is possible to know that the diaper is wet by selecting the above three means. In the present invention, the voice of the cared person can be reported as a live voice such as “XX, but please change your diaper.” Or, it is reported as a sound such as music or signal selected independently. Thus, these are made to flow repeatedly during the operation of the sensor by a command signal as shown in the signal processing circuit diagram example of FIG.
In the present invention, a caregiver can have a portable FM radio outdoors, so that the wet state of the care recipient can be accurately known even at a distant location. In other words, it will be possible to improve appropriate services for efficient nursing and management in elderly facilities and hospitals.

It is a flow sheet figure showing an embodiment of the device of the present invention. It is a circuit diagram of a reporting device. It is a top view of the electrode plate which concerns on a sensor. It is a circuit diagram of signal processing.
