Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for detecting excretion in a diaper, and more particularly to a device capable of accurately notifying a caregiver of the fact that a cared person excreted in a diaper.

[0002]

[Prior art]

 Infants, elderly people, bedridden sick persons, injured persons, etc. may have to make diapers because they cannot handle excrement themselves, but if there is excretion in the diaper, it is hygienic if left as it is. Because of the problem, the caregiver needed to know the facts of excretion as soon as possible and take appropriate post-treatment such as changing diapers. In other words, as a caregiver, it is absolutely necessary to know the facts of excretion as soon as possible, but in the past, caregivers put their fingers into diapers and knew from the feel of their fingers. This method is not only unhygienic, but also efficient, and is an excessive burden for caregivers who have to care for a large number of caregivers.

[0003]

[Problems to be solved by the device]

 As described above, it is extremely important for a person who cares for a person who wears a diaper to know the fact of excretion, and some devices have been proposed in the past to notify the fact of excretion by some method. These devices electrically detect and display the wetting and odor in the diaper, but they are both unreliable and expensive, and it is impossible to widely spread them in terms of cost, and it is impossible to use them for nursing care. As usual, the caregiver was burdened with an excessive burden.

The present invention is intended to solve the above problems during nursing care, has a simple structure, is less likely to malfunction, and is excreted without causing discomfort to the cared person. The purpose is to provide a hygienic alarm system for detecting excretion in a diaper, which can inform the caregiver appropriately.

[0005]

[Means for Solving the Problems]

 In this invention, a crystal oscillator odor sensor 2 and a drive circuit 3 provided behind it are fixed to a base 13 and a tongue-shaped sensing unit 1 is provided only in a portion corresponding to the crystal oscillator odor sensor 2. The sheath material 4 made of soft synthetic resin foam made of closed cells with ventilation holes 5 is detachably covered, and the signal from the odor sensor 2 is input and compared with a preset value. The main body box 6 including the comparison / determination circuit 7 for determining the presence or absence of excretion and the display unit 9 for displaying the determination result by the lamp 8 in response to the signal from the comparison / determination circuit 7 is connected to the sensing unit 1 and the flexibility. The above problem is solved by electrically connecting with a rich conductor wire 11.

[0006]

[Action]

 The sensing unit 1 is inserted into the caregiver's diaper, and the main body box 6 is placed at an appropriate position, such as a nurse suite, away from the caregiver and easy for the caregiver to see. When the diaper is excreted in the diaper, the crystal unit odor sensor senses the change in the diaper due to the excretion and sends a signal to the main body box 6 when the diaper is excreted. Is output. The comparison / determination circuit 7 in the main body box 6 compares it with a preset value to determine the presence or absence of excretion, and outputs the determination result to the display unit 9 as an electric signal. The detection result is displayed by turning on.

The sensing unit 1 uses the crystal oscillator odor sensor 2, and the odor inside the diaper is sensed from the decrease in the frequency of the crystal pendulum due to the adsorption of the odor substance, so that the fact of excretion can be known. Therefore, the detection accuracy is extremely high, and even a slight incontinence of urine can be detected.

Since the surface of the sensing unit 1 is covered with a sponge material 4 made of sponge-like soft synthetic resin composed of closed cells, excretion is performed and whenever the dirt material 4 is replaced, the sheath material 4 can be replaced. This device can be used in clean condition.

【Example】

 FIG. 1 is a block diagram of an embodiment of an alarm device for detecting excretion in a diaper according to the present invention. In the figure, reference numeral 1 denotes a flat tongue-shaped sensor unit 1. The sensor unit 1 has a crystal oscillator odor sensor 2 fixed to its tip and a crystal oscillator odor sensor 2 located behind it. And a drive circuit section 3 for driving the motor are fixed on the substrate 13, and all of them are removably covered with a sheath material 4 made of sponge-like soft synthetic resin foam having closed cells. . A large number of ventilation holes 5 are provided only at a portion of the tip portion of the sheath material 4 that comes into contact with the odor sensor 2. In FIG. 1, the sensing portion 1 is cut out so that the inside can be seen.

The crystal unit odor sensor 2 is a sensor in which the surface of the crystal unit is uniformly covered with a synthetic bilayer film. When an odor substance is adsorbed on the synthetic bilayer part, the weight of the adsorbed odor substance is measured. The scent is sensed by the phenomenon that the frequency of the crystal unit decreases in response to this, and the decrease in frequency is output as an electrical signal to the outside.

On the other hand, reference numeral 6 in the drawing denotes a small box-shaped main body box, into which the signal from the odor sensor 2 of the sensing unit 1 is input and compared with a preset value. A built-in comparison judgment circuit 7 for judging the presence or absence of excretion and its degree, and a display unit 9 for displaying the judgment result externally by turning on a lamp 8 based on a signal from the comparison judgment circuit 7. In this embodiment, the set value in the comparison / determination circuit 7 can be arbitrarily set to each level obtained by dividing 0 to 1,000 into eight equal parts, and the set value is set in the main body box 6. The level can be changed by operating the attached level setting switch 10.

Reference numeral 11 in the figure is a flexible conductor wire for electrically connecting the sensing unit 1 and the comparison / determination circuit 7 of the main body box 6, which is several meters, and is about 4.5 m in this embodiment. Have a length. Since one end of the conductor 11 is inserted into a diaper of a care receiver who is lying on a bed, a futon or the like, it is important that the conductor 11 is flexible and does not give the care receiver a foreign body sensation. In addition, since a plurality of main body boxes 6 are gathered in one place and are often centrally managed, the conductor wire 11 cannot necessarily be relatively long. If the connection socket 12 is provided in the, it will be easier to handle and convenient.

Next, the operation of this embodiment will be described. The sensing unit 1 is inserted into the caregiver's diaper, and the main body box 6 is placed at an appropriate position, such as a nurse suite, away from the caregiver and easy for the caregiver to see. It is used by being electrically connected at 11. When excreted in the diaper, an odor substance is released from stool or urine, and the odor substance is adsorbed by the synthetic bilayer membrane of the odor sensor 2. Due to this adsorption, the weight of the synthetic bilayer membrane increases, and along with this, the quartz oscillator becomes difficult to vibrate, and its frequency decreases. The reduced frequency is taken out as an electric signal and output to the body box 6. The comparison / determination circuit 7 in the main body box 6 compares the preset value with the preset value to determine the presence / absence of excretion, and outputs the determination result to the display unit 9 as an electric signal. The detection result is externally displayed by turning on the light. The set value in the comparison / determination circuit 7 can be arbitrarily set to each level by dividing the range from 0 to 1,000 into eight parts by operating the eight level setting switches 10 attached to the main body box 6. .

Further, since the surface of the sensing portion 1 is covered with the sponge-like soft synthetic resin pod 4 having closed cells, the pod 4 can be easily replaced every time it is excreted and becomes dirty. It is possible to keep the device in a hygienic condition at all times.

[0015]

As described above, the diaper excretion detection alarm device according to the present invention uses an extremely high-sensitivity crystal oscillator odor sensor, and can detect the presence or absence of excretion of a cared person with high accuracy. As well as being able to do so, the sheath material covering the sensing part is disposable once, so it is extremely hygienic and extremely effective for caring for infants, the elderly, seriously ill people, etc., and has an excellent effect of reducing the burden on the caregiver. .
