Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excretion detector which is used for a diaper and detects urination and defecation when it occurs.

[0002]

2. Description of the Related Art In recent years, excretion detectors have been developed for nursing care for bedridden elderly people and the sick, in order to quickly detect urination and defecation and quickly and accurately change diapers. I have.

[0003] Most of such excretion detectors are, as a representative example, a detection unit for detecting urination or defecation between a body and a diaper (referred to as the inside of the diaper) as disclosed in Japanese Patent Application Laid-Open No. 9-294762. Is provided, and a signal detected there is transmitted via an electrode to a main body attached to the sensor paper, but the sensor paper is directly applied to the inner side of the diaper, that is, a local part of the body. It is a structure that can be attached to.

[0004]

The drawback of this structure is that, first of all, it gives the elderly or bedridden patients the physiological discomfort associated with applying sensor paper directly to a local part of the body. . In other words, the soft touch of the diaper
That is, the sheet is damaged by the interposition of the sheet. Second, since the detection section is integrally formed with the sensor paper, disposal is troublesome because the sensor paper containing the detection section is filth with excretion.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such a problem, and it is possible to detect the presence or absence of urination or defecation in a diaper by attaching the diaper to the outside of the diaper. It is the excretion detector characterized by doing so. Because of this, the excretion detector is attached to the outside of the diaper, so it is not necessary to disposable like sensor paper and it is not only economical and not garbage, but also it is not in contact with the body. It does not give an uncomfortable feeling, and furthermore, it is not necessary to provide a diaper inside each time like a sensor paper so as to be provided between the body parts.

In addition to the ultrasonic sensor 110, a state detection circuit 111, a determination circuit 112, a timer circuit 113 for enabling electric transmission after a predetermined time from the detection by the ultrasonic sensor 110,
It comprises a transmission circuit 114 and an antenna 120. The ultrasonic sensor 110 is set so that the diaper 300 emits intermittently about once a minute in order to extend the life of the battery 140.

FIG. 6 shows an excretion detector 100 according to the present invention.
FIG. 4 is a schematic diagram of an external appearance of a receiver 500 for receiving a signal transmitted from a receiver. The display unit 520 includes a battery replacement lamp 520a for battery consumption determination, and a call lamp 520 that urges a caregiver to change diapers in conjunction with a buzzer.
b, when a sick person or the like wearing the excretion detector according to the present invention wanders, resets a wandering lamp 520c that operates upon receiving a signal from a wandering sensor (not shown), an excretion lamp 520d that displays an excretion state, an excretion lamp, and the like. For example, an indicator lamp such as a reset switch 520e is provided.

Next, the operation based on the block shown in FIG. 5 will be described. Ultrasonic waves emitted from the ultrasonic sensor 110 are intermittently emitted about once a minute in order to extend the life of the battery 140. The first emission is emission without excretion (hereinafter, referred to as “urination”), and the sound pressure level of the reflected wave received by the ultrasonic sensor 110 is transmitted to the state detection circuit 111. The state detection circuit 111 converts the signal into an electric signal corresponding to the sound pressure level,
Send to 12 In the determination circuit 112, the voltage change of the electric signal is converted into a digital signal by an A / D converter to be learned for comparison and discrimination, and the electric signal may be passed through the timer circuit 113 (a circuit configuration not passing through the timer circuit 113). )) When the urine is discharged and the urine enters the ultrasonic irradiation area A, the reflected wave of the ultrasonic wave emitted from the ultrasonic sensor 110 similarly passes through the state detection circuit 111 when the urine is discharged to the transmission circuit 114. Then, it is transmitted to the determination circuit 112. In this determination circuit 112, a comparison is made with a signal waveform that has already been learned. When the determination circuit 112 recognizes that there is a difference of a certain level or more in the compared waveforms, it determines that urination has occurred, and transmits a received signal to the timer circuit 113.

After a predetermined time has passed in the timer circuit 113, the transmission signal is transmitted through the transmission circuit 114 to the transmission antenna 120.
To the receiving unit 510.

As described above, the excretion detecting apparatus 100 includes the state detecting circuit 111, the judging circuit 112, the timer circuit 113 and the transmitting circuit 114, and the parts constituting these are provided on the printed circuit board 130. Note that the state detection circuit 111, the determination circuit 112, and the timer circuit 113 may be provided in the receiving unit 510.
