Description

The present invention relates to a urine detection system, and in detail, a diaper wearer (elderly / infant and other diaper users) who does not use an IC tag but uses a urination detection tag sensor having a simple tag structure that switches. It relates to a urination detection system that realizes urination detection.

In general, excretion is an important basis of life, which is performed every day like eating.

The most important role that a diaper should play for a diaper wearer is to prepare and support this excretory environment.

Among diaper wearers, for example, the excretion of elderly people who use diapers is a very delicate problem related to self-esteem, so first understand the feelings of elderly people who use diapers, and with correct knowledge and skills. If you can master adult diapers, you can change from "heavy burden" to "subtle acceptance" of excretion care even if some trouble occurs.

Next to the role of life support for the elderly who use diapers, the important factor is to reduce the burden on the caregiver himself.

In order to realize excretion care with less burden on both the caregiver and the caregiver, it is indispensable to utilize appropriate "excretion aid products for the elderly".

For example, if urination can be automatically detected and an appropriate report can be received, it helps to reduce the burden on the caregiver, and the caregiver can also reduce discomfort.

The last major factor is the prevention of secondary troubles on the skin of the elderly. The protective function of the skin of the elderly is weakened, and the irritation of excrement and friction with diapers cause "swelling" and "rashes". It is in a state where secondary troubles such as "bedsore" are likely to occur.

When keeping daily life clean and performing appropriate excretion care such as cleaning the pubic area, such as using "diapers (for adults)" with high water absorption and breathability, excrement if the time to change the diaper is clearly known. It is clear that it is possible to protect the skin from irritation and prevent secondary troubles.

Patent Document 1 describes a urine detection unit that is attached to a diaper worn by a diaper wearer and has an effect of capturing a change in a predetermined inductance (that is, a current flowing through a coil) and a change in capacitance (that is, capacitance) under a normal state. I used an IC tag that stores personal information in an electromagnetic induction type passive type (however, in this case, the IC tag and IC chip are not used, and personal authentication is held as an ID in the controller body, but there is no personal authentication. , The tag is for changing the weak electromagnetic field transmitted from the antenna laid under the bed mat by getting wet with urine.) The urine sensor and the bedding such as under the mattress or the duvet used by the diaper wearer. An arbitrary number possessed by a sensing antenna that is electromagnetically induced and coupled to the urine sensor, urination monitoring including personal information of the diaper wearer, and a caregiver or the like in charge of caring for the diaper wearer. The management computer that distributes data to the mobile information terminal, supplies the required power to the sensing antenna, electromagnetically induces and couples the sensing antenna and the urine sensor, and wirelessly or wiredly connects the management computer. A urine detection system including a transmission / reception controller that transmits data and transmits data to and from the urine sensor via the sensing antenna, the inductance due to the presence of urine in the urine detection unit of the urine sensor (that is, a coil). The urine sensor is switched from off to on by utilizing the electromagnetic induction coupling based on the change of the current flowing through the current and the change of the capacitance (that is, the capacitance), and the time when the urine sensor is turned on is detected as a urine detection signal by the management computer. Then, a urine detection system configured to send a urine detection report including personal information to the mobile information terminal based on the urine detection signal has been proposed.
