Description

Wireless defecation urination alarm {A wireless evacuation piss alarm}

The present invention relates to a countermeasure when a user wearing a diaper causes bowel movements or urination. More particularly, the present invention relates to a method of electronically controlling feces generated in a diaper. A method of transmitting and receiving at a receiver.

The present invention is to be used for people who can not process the treatment of urination by yourself as an alarm for distinguishing feces or urine by calculating the resistance value with the electrode 30 inside the diaper during urination or defecation.

For example, infants, the elderly, patients and the like are treated with urine care. Therefore, caregivers should change their diapers immediately when they have a small urine, so as to prevent the occurrence of diseases such as eczema due to the wetness of the diaper and diaper rash due to the sore of the hips. However, infants, the elderly, patients, and the like are usually unable to express themselves on their own, so they cannot express their opinion about urine or suffer from shame.

Therefore, in order to solve this problem, there are diapers that can check the presence of faeces by printing a specific color on the diaper and seeing the discoloration due to the absorption of the urine. It was more inconvenient to wear the pants on top, there was a problem that one-time use can not be used in conventional general diapers or underwear because only a specific color of the printed diapers should be used.

And there is a diaper that is equipped with a moisture sensor in the diaper to sound a warning sound in the case of urine, but there is a problem of noise caused by the warning sound, the problem of increasing the shame of the patient, the guardian should always be waiting around.

In addition, in order to solve this problem, a wireless remote urination detection device is disclosed in Korea Patent Publication No. 199595-12182 to solve the conventional problem that the guardian should be around, but by separating the feces and urine Infant and the like had a problem of generating a signal just by urinating once.

In order to solve this problem, a diaper manure automatic detector is disclosed in Korean Utility Model Registration No. 0257941. This design is designed to detect urine and feces by installing two sensors in different positions. However, there is a problem in that the urine is configured to distinguish the urine according to the position of the sensor as described above.

The present invention is to measure the resistance of feces and urine hundreds of times by attaching an electrode inside the diaper to solve the above problems, the resistance of feces and urine is between 1K ~ 4K and the difference in resistance between feces and urine In other words, stool may have less resistance than urine, and urine may have less resistance than stool. The reason for this is the difference in diet between meals and mother's dietary habits. The difference in resistance between urine and urine varies according to different infants.

As a result, the discharge of urine and urine varies from person to person, and the time of urination or defecation is different and the dietary habits also have different resistance values.

In order to accurately measure urine and urine, the present invention places an electrode capable of detecting a resistance value in the diaper when the urine is discharged from the urine for the first time. The second measurement was performed to calculate the difference between the first and second measurements, so urine penetrates the diaper, but feces do not penetrate.

The present invention can be used while the user is wearing a diaper, and commercially used diapers immediately penetrate the diaper within a few seconds when urine is discharged, and the resistance of urine increases rapidly and the time to discharge urine is also investigated. In general, the average person discharged everything from 3 to 20 seconds, and the interval between the first and second measurements was 30 seconds. At that time, the urine penetrated the diaper, resulting in no resistance or a sharp increase in stool. Since the moisture is gradually absorbed into the diaper without being penetrated into the diaper, the resistance value is maintained, and the resistance value 40 is converted to an analog voltage to a digital voltage by the A / D converter 50, measured and calculated by the microcomputer chip 60, and then the RF signal 60 is obtained. It is characterized by consisting of the step of sending out).

According to the present invention, when a user wearing a diaper generates feces or urine, the receiving unit 500 displays feces and urine according to a control signal output from the transmitting unit 20, and the urine displays the numeric plate 510 and the LED 520. It is possible to know how many times the urine is discharged through, and the stool generates a melody through the speaker 550 and turns on the LED 540 so that the guardian can immediately change the diaper to prevent dermatitis such as diaper rash or eczema. In addition, when urine is discharged more than 3 times, an audible signal is immediately generated so that the guardian can immediately change the diaper, thus protecting the health of the diaper user.

The present invention will now be described in detail with reference to the accompanying drawings.

The present invention is installed on the diaper 10 and the diaper 10, when the detection electrode 30 is attached to the inside of the diaper 10, when feces or urine is detected on the detection electrode 30 when the urine is seen (100) ) Send the wireless A signal 110, measure the resistance 5 times the first time (120) and convert it to the A / D converter 50, memorize the average value of the first measured value in the microcomputer chip (60) and average urination time Referring to FIG. 3A and the diaper absorption time of the urine and urine (FIG. 2), wait 30 seconds for 130 seconds, and after 30 seconds, measure the resistance twice inside the diaper five times (140) and A / D converter (50). ), The average value of the secondary measurement values were stored and stored in the microcomputer chip 60, and the stool and urine were distinguished by the comparison difference between the primary and secondary measurements.

In the present invention, the individual urination time measurement value (Fig. 3A) shows that the average urination time (400) is 10 seconds (440) and most do not urinate for 20 seconds or more, and the interval between the first measurement and the second measurement was 30 seconds. Referring to the diaper inhalation time of the urine (Fig. 2A), it was found that after 20 seconds (320), the urine was penetrated into the diaper, so the resistance increased rapidly.

In the case of stool, resistance is maintained even after 30 seconds (380) because it does not penetrate the diaper 340, and a slight increase or decrease (350) or decrease (360) even when the stool and urine are discharged at the same time or at a time difference. You can see that you have excreted

Therefore, in the microcomputer chip 60, the difference between the first measurement and the second measurement is set to 50%. When the change is 50% or more from the value of the first measurement, the microcomputer chip 60 transmits the wireless C signal by determining the urine detection 170 and then 50. If the change is less than or equal to%, it is determined by the stool detection 150 to transmit the wireless B signal 160.

In the case of the stool, the transmitter 20 continuously transmits the wireless B signal 160 with a time difference until the diaper is replaced by the guardian. Goes

Preferably, the transmitter 20 transmits a radio signal differently for each device so that a plurality of infants, such as a nursery school, are used to transmit radio signals differently. It is characterized in that it is configured to determine whether the urination and wireless transmission and reception of the control signal.
