Description

[Detailed Description of the Invention] The present invention detects moisture and activates a receiver located in a remote direction, so that a third party can detect when an infant or a bedridden elderly person uses the toilet. The present invention relates to an oscillator that can sense moisture in a disposable diaper that can be immediately sensed and replaced.

BACKGROUND OF THE INVENTION In recent years, as society ages and the number of people living longer lives increases due to advances in modern medicine, there is a tendency for the number of so-called ``sleepy old people'' to increase. In geriatric hospitals, more than 30% of them are
Disposal of urine and feces is a major problem when caring for these patients, and if only the urine could be easily disposed of, the burden on patients and nurses would be reduced. This is thought to lead to mitigation.

Conventional methods for treating urine are broadly divided into treatment after natural urination using devices such as diapers, and treatment for continuous urination using an indwelling catheter such as a balloon catheter. To further discuss the treatment using the orthosis mentioned above, since it is unknown when a patient, elderly person, or infant has used the toilet, nurses may take measures such as changing the diapers of many patients at the same time at different times. is the current situation. However, when such treatment is performed, some patients may continue to defecate for a long time, causing discomfort and causing pain such as diaper rash, coldness, and pressure sores. It has become.

In order to deal with the above, the applicant of the present application first applied for the U.S. Pat.
According to No. 202267, a thin metal layer is formed in a diaper using moisture contained in excrement, and the thickness of the thin layer corresponds to the amount of moisture adsorbed on an adsorption layer in the diaper. We are proposing a device that can immediately confirm a patient's urinary status by detecting electrical conductivity. According to such a device, the name of the patient who has used the toilet can be immediately known by activating the alarm for each individual, so that the diaper can be changed.

The present invention improves the moisture detector for disposable diapers that can detect the moisture in the diaper as described above, making it easier to use.
Moreover, it is an object of the present invention to obtain a disposable diaper that is in good operating condition.

In order to achieve the above object, the present invention comprises at least a moisture-permeable top sheet, a moisture-impermeable back sheet, and a water-absorbing layer located between the two sheets, and A disposable diaper with a metal layer whose electrical conductivity changes depending on the amount of moisture adsorbed into the water-absorbing layer is attached between the water-impermeable back sheet and the water-absorbing layer. The metal layer is clamped and fixed to a pair of clips provided at one end, and is led out from the clip.
The main object of the present invention is to obtain an oscillator capable of sensing moisture in a disposable diaper, characterized in that an oscillator that oscillates by detecting a change in electrical conductivity of a metal layer by being connected to a conductive wire is housed in the waterproof case. There is.

Nu11sen The present invention will be described in detail below based on the drawings.

FIG. 1 is a plan view showing an embodiment of an oscillation device capable of sensing moisture in a disposable diaper according to the present invention, and FIG. 2 is a sectional view taken along line nn in FIG. 1. In the figure, 1 is a water-permeable top sheet, 2 is a water-absorbing layer, and 3 is a water-impermeable back sheet. The surface sheet 1 has a basis weight of 10 to 30 g/rr?
The water-absorbing layer 2 is a structure made of cotton-like pulp, tissue paper, etc., or a super-absorbent polymer.

The back sheet 3 is made of polyethylene, polyester, etc. with a thickness of 1
It is a plastic film of 5 to 40 μm. On the other hand, four metal layers 4.4 between the water absorption layer 2 and the back sheet 3,
... is deposited and formed. This metal layer 4.4 is provided in at least two or more strips, and is formed on the back sheet 3 by laminating or vapor-depositing a material such as aluminum, zinc, copper, or tin. It has reached this point. At the end of the back sheet 3, the metal layer 4.4 is covered with the top sheet 1, or is exposed for an appropriate length. Reference numeral 5 indicates an adhesive tape, which is used for feces when the diaper is put on.

6.6 is a lead wire from the metal layer 4.4, and this lead wire 6.6 is connected to a small oscillator 7. The oscillator 7 is equipped with an electronic circuit that detects changes in the electrical conductivity of the metal layer 4.4 and operates to oscillate, and a receiver 8 placed at a remote location senses the activation of the oscillator 7. , amplifier 9
The alarm device IO is operated via the .

Figure 3 is a small 9! This shows an example of how to install the vibrator 7, and the female type 12.1 is placed above and below the opening of the separately prepared waterproof case.
forming a pair of clips consisting of 2 and female 13.13;
One end is fixed to the female wire 12.12 (or the female wire 13.13), and a wire 6.6 is led out, and the other end of this wire 6.6 is connected to the oscillator 7. The clips 12 and 13 as a pair reach the end of the back sheet 3 and are covered with the top sheet 1, or contact and fix the metal layer 4.4 which is exposed for an appropriate length by sandwiching it. Accordingly, metal layer 4
．． 4 and the oscillator 7 are electrically connected. As the waterproof case 11, a bag body made of synthetic or artificial leather is used to improve sealing performance, and the clip is plated with nickel or chrome to have a rust-resistant structure. In addition, in order to improve the contact between the clip and the metal layer 4, a protrusion may be provided on the clip side so as to be crimped with the metal layer 4.

FIG. 4 shows an example of the configuration of the oscillator 7, which includes an oscillation circuit 16 containing a button-type battery 14 and connected via a low resistor 15, a Riet wire 6.6 led out from a terminal 17.17, and a switch. It consists of 18.

The operation of the device of the present invention having the above configuration is as follows. A female mold 12.12 and a female mold 13.
A metal N4.4 is sandwiched in the inside 13 and fixed with a clip, and the switch 18 is turned on. When moisture flows into the water absorption M2 in this state, the electrical conductivity between the metal layers 4 and 4 changes, so that the battery 14 and the oscillation circuit 16 are closed, and the oscillation circuit 16 generates an oscillation output.

This oscillation output is received by a receiver 8 installed in a nurse center or the like, and the alarm 10 is activated via an amplification m9, thereby making it possible to confirm the patient's urinary status. Note that, of course, an alarm lamp may be used as the alarm 10 in addition to a buzzer.

Effect of Clarity The structure and operation of the oscillation device capable of sensing moisture in a disposable diaper according to the present invention have been described in detail above, and by using the present invention, various advantages described below can be brought about as effects. Namely, the patient;
When the oscillator device capable of detecting moisture in disposable diapers according to the present invention is used in a hospital etc. where a large number of elderly people, infants, etc. Since the name of the patient who has used the toilet in the nursing center can be immediately recognized, by changing the patient's diaper, the patient does not feel uncomfortable and can achieve a usage condition that is hygienic. Since the oscillator is housed in a completely waterproof case, it is highly watertight and there is no risk of malfunction. In addition, the method for attaching the diaper to the diaper is simply to fasten the clips, making the method of use extremely simple and easy. Furthermore, since the waterproof case, oscillator, etc. can be made smaller, they do not get in the way when wearing the diaper, and do not cause discomfort to the patient. The diaper and the oscillator are separate structures that can be detached and removed, and the diaper only needs to have a metal layer attached to it, so the diaper itself is easy to process and can be provided at low cost as a disposable diaper. . Therefore, after use, the waterproof case can be removed and the diaper itself incinerated, and it can be reattached to a new diaper for use.
It is mainly useful when used in disposable diapers.
