There is a problem being In addition, when the wearer moves while wearing a diaper after defecation or urination, the amount of moisture on the surface of the detection sensor changes, thereby reducing the reliability of urine detection.

In addition, looking at the conventional urine detection sensor patent (Patent Registration No. 10-1498112) containing a fiber yarn containing a conductive wire that is easy to apply to a diaper, the conductive wire is fixed in the production process to be mounted on the diaper, It is provided when selling diapers so that they can be attached and used when using them.

However, in the case of the existing diaper, there is a limitation in that it can be used only in the form provided to the supplier in order to attach the conductive wire to the diaper because it has various sizes. In other words, if the detection sensor can be cut out to fit the various diaper sizes currently on the market and provided in the form of a detachable patch, it is possible not only to escape the limit of providing the detection sensor, but also to increase the economic efficiency by distributing the detection sensor in large quantities. There is an urgent need for rapid development in

It is configured to include 220 , and the electrically conductive material is disposed between the nonwoven fabric 230 and the woven fabric 220 .

First, as shown in FIG. 1, the electrically conductive material of the sensing means 200 according to the present invention is made of electrically conductive fiber yarn 210 or conductive ink. will create In this case, in the case of the electrically conductive fiber yarn 210, a power terminal 250 for supplying power is connected to one end, and an output terminal 260 for outputting a sensing signal is connected to the other end of the electrically conductive fiber yarn 210. Therefore, when the wearer's feces and urine are absorbed, the power supply voltage is supplied from the power terminal 250 in a fixed (or regular period), and a detection signal of the feces and urine is output through the output terminal 260 .

In this case, the electrically conductive fiber yarn 210 may have a diameter of 100 to 5000 denier or less. In this case, the diameter range may be a range in which appropriate moisture required for detecting urine and feces can be absorbed.

In addition, the resistance value of the electrically conductive fiber yarn 210 may be formed to be less than or equal to 50 Ω (ohms), preferably within a range of 0.001 to 30 Ω. This resistance value will be in a range in which a detection signal can be generated when the conductive fiber 210 absorbs urine and feces.

As shown in FIG. 3 , one or more copper metal filaments 211 may be wound around the outer circumferential surface of the fiber filament 212 to form a single conductive fiber yarn 210 .

For example, the two strands of the metal filament 211 may be overlapped and wound in an x-shape on the outer circumferential surface of the fiber filament 212 , but the present invention is not limited thereto.

As another example, one conductive fiber yarn 210 may be formed by winding or weaving 40 or more of the fiber filament 212 and the stainless metal filament 211 .

As another example, one conductive fiber yarn 210 may be formed by winding or weaving two or more strands of the fiber filament 212 and the silver filament 211 .

As another example, one conductive fiber yarn 210 may be formed by winding or weaving two or more strands of the fiber filament 212 and the silver-plated copper filament 211 .

At this time, when winding or weaving the metal filaments 211 on the outer circumferential surface of the fiber filaments 212, the spacing between the metal filaments 211 is not limited as long as the fiber filaments 212 and the metal filaments 211 are not separated.

In addition, when the electrically conductive material is conductive ink, it is printed on the fabric with a certain width in the longitudinal direction, and when the wearer's feces and urine are absorbed, a detection signal is generated.

Further, as shown in FIG. 7, the sensing means 200 according to the present invention receives a sensing signal, and a transmitting unit 270 for generating and transmitting sensing information for determining the leakage amount and the leakage time step-by-step based on the detection signal, and It may be configured to include a receiver 280 that receives the detection information from the transmitter 270 and outputs the detection information.

That is, when the transmitter generates and transmits the sensed information for the signal sensed by the sensing means 200, the receiver 280 receives and outputs the sensed information so that the guardian can directly check the urine and feces detection information.

In this case, the transmitter 270 includes a signal processor that receives and processes the detection signal, a signal indicator that displays the result processed by the signal processor, a transmitter and a signal processor that transmits the detection information through wired or wireless communication, the signal indicator and the transmitter. The transmitter 270 for controlling the operation may include a Micro Control Unit (MCU).

In addition, the receiver 280 may include a receiver for receiving detection information from the transmitter 270 , an information indicator for displaying the sensed information received from the receiver, and a receiver 280 MCU for controlling the operations of the receiver and the information indicator. In this case, the receiver displays the detection information on the urine output from the receiving unit 280 MCU on a display device such as a liquid crystal display, so that the guardian can directly check the detected information, such as a mobile phone, a computer, etc. commercialized communication devices. can be composed of In this case, a commercially available communication device such as a mobile phone or a computer may receive the sensed information from the transmitter 270 , process the sensed information by a program installed in the communications device, and display it.

In addition, the receiver 280 may be linked to a system such as a biometric monitoring system, and the receiver 280 adds a unique identification number to the detection information, thereby detecting a plurality of transmitters 270 and one receiver 280 . It is also possible to constitute the means 200 .

As shown in FIGS. 1 to 5, the sensing means 200 according to the present invention is stacked in the order of the fabric 220, the non-woven fabric 230, and the detachable part 240 from the top as described above, and the fabric fabric ( 220) and the non-woven fabric 230, the electrically conductive fiber yarn 210 is disposed, or in the case of conductive ink, since it is printed on the fabric fabric, it may be disposed between the fabric fabric and the non-woven fabric.

First, the fabric 220 of the sensing means 200 is disposed on the uppermost part and is in direct contact with the wearer's skin, so that skin troubles do not occur by using fabrics or knitted fabrics such as natural fibers and organic fibers. It is preferable to use a human-friendly material.

Next, the nonwoven fabric 230 of the sensing means 200 is preferably disposed under the fabric 220, and made of a hydrophilic fiber or hydrophilic nonwoven fabric so that the wearer's feces and feces can be absorbed.

In this case, an electrically conductive fiber yarn 210 or conductive ink is disposed between the woven fabric 220 and the nonwoven fabric 230, and the bonding method between the woven fabric 220 and the nonwoven fabric 230 is a thermal fusion method by ultrasonic lamination. It is preferable to apply As in the case of the conventional adhesive method using hot melt using acrylic or urethane, it is a contact method using synthetic resin, which can cause skin troubles when worn for a long time, so it is harmless to the human body through adhesion by ultrasonic lamination. This is to provide a friendly sensing means 200 .

In addition, the detachable part 240 of the sensing means 200 is made of velcro so that the sensing means 200 can be attached and detached from the diaper body 100 . In this case, it is preferable to apply a micro velcro to the Velcro, which is to ensure the ease of attachment and detachment by using a micro Velcro rather than a normal Velcro.

In particular, as shown in (c) of FIG. 3 , it is preferable that the detachable part 240 has a width smaller than the width size of the nonwoven fabric 230 , which is the same as the width of the detachable part 240 as the nonwoven fabric 230 . Or, if it is large, the detachable part 240 completely covers the nonwoven fabric 230 and acts as a tarpaulin, which may interfere with the absorption of urine and feces. Therefore, it is preferable to make the width size of the detachable part 240 smaller than the width size of the nonwoven fabric 230 to secure a portion where the diaper body 100 and the nonwoven fabric 230 can come into contact to ensure absorption of urine and feces. In addition, in order to further increase the absorption power of the sensing means 200, it is also possible to prevent the detachable part 240 and the electrically conductive fiber yarn 210 from overlapping each other. In this case, the detachable part 240 is the electrically conductive fiber yarn 210 when the woven fabric 220 and the nonwoven fabric 230 are located in the middle, the detachable part 240 is the electrically conductive fiber yarn 210 or conductive ink based on the It is possible to be disposed on one side, or disposed on both sides based on the electrically conductive fiber yarn 210 or the conductive ink as shown in FIG. 3C .

The sensing means 200 configured as described above is provided in a state of being wound like a tape as shown in FIG. 3 (a) and is configured in a patch form that can be cut and used, which is because commercially available diapers have various sizes. After the detection means 200 is cut to an appropriate length according to the size of the diaper, the detection means 200 is attached to the diaper for use.

This means that conventionally marketed diapers have various sizes depending on age, function, usage, and the like. In this case, the feces and urine detection means 200 using the electrically conductive fiber yarn 210 or conductive ink is fixedly attached to or embedded in the diaper during the production process of the diaper and shipped, or is manufactured to fit the size of the diaper of the product so that the user can use it. It can be attached and used as needed. That is, the sensing means 200 that can be used only for the size of a commercially available diaper is provided. Therefore, there is a limit to the application of the sensing means 200 to the existing diaper. There is a problem that the size of the diaper is limited.

In the present invention, in order to solve this problem, the woven fabric 220, the nonwoven fabric 230 and the detachable part 240 are configured, and the electrically conductive fiber yarn 210 or conductive between the woven fabric 220 and the nonwoven fabric 230 is The detection means 200 on which ink is disposed is provided in a wound state in the form of a tape, the detection means 200 is cut to fit the diaper size having various sizes, and the cut detection means 200 is attached to the diaper to use it. do. In this case, it is possible to secure the convenience of use by introducing the detachable part 240 made of Velcro in the lowermost layer of the sensing means 200 so that the sensing means 200 can be more easily attached and detached from the diaper.

In addition, the sensing means 200 manufactured in the patch type can be supplied at a low cost because it can be supplied in large quantities, and since there is no need to install the sensing means 200 on the diaper or manufacture it to fit the size of the diaper, from the supplier's point of view production cost can be lowered. From the user's point of view, by purchasing a large amount of the sensing means 200, not only can it be purchased at a low price, but it can also be cut to an appropriate size according to the size of the diaper and used, thereby reducing waste of material and increasing economic efficiency.

1 and 5 show that the plurality of sensing means 200 are arranged in a linear form in parallel to each other with a predetermined interval between the diaper body 100 . In addition, it is also possible to use the demagnetizing means arranged in a single row, but for the sensitivity of the detection signal of feces and feces, it is preferable to use the sensing means 200 by arranging it in a plurality of rows on the diaper body 100 .

As such, the present invention has been described with reference to one embodiment shown in the drawings, but this is merely exemplary, and those of ordinary skill in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. will understand
