Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. In this process, the size or shape of components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms specifically defined in consideration of the configuration and operation of the present invention may vary depending on the intention or custom of the user or operator. Definitions of these terms should be made based on the contents throughout this specification.

1 is a schematic view showing an absorbent article of the present invention.

The absorbent article illustrated in FIG. 1 may include a sheet unit 100 and a terminal unit 500.

The sheet portion 100 may be provided with a pattern 200 through which electricity is communicated. Two or more patterns 200 may be formed to be spaced apart from each other in the excretion area k of the sheet portion 100 receiving the user's excrement.

The user may include a person or an animal wearing the seat portion 100.

The user's excrement may include feces, urine, sweat, menstruation, tears, saliva, and the like. In order to receive each excrement, the sheet portion 100 is a diaper or pad that receives feces, a pad or patch that is attached and sweats to a specific location on the user's body, a sanitary napkin that receives physiological products, a eye patch that receives tears, a mask that receives saliva, etc. It may include.

The illustrated seat portion 100 may include a diaper filled between the legs of a user and receiving urine. Each configuration shown can be applied to other types of sheet portion 100, such as sanitary napkins.

A pair of tape fasteners 190 may be installed at one edge of the diaper. The tape of the tape fastener 190 may be attached to the other edge of the diaper.

A pair of cuffs 170 for preventing leakage may be provided on both sides of the diaper in an upright position.

2 is a schematic view showing a cross section of the sheet portion 100.

The sheet portion 100 is a first sheet 110 of a material in which passage of excrement is at least partially restricted, and a second sheet 120 of a material laminated on one surface of the first sheet 110 facing the user and through which excrement passes. It may include.

As an example, the first sheet 110 may include a material such as vinyl, film, etc., for example, polyethylene in which the user's excrement is not discharged to the outside.

Some shapes of the first sheet 110 may be changed in consideration of a wearing position of the sheet unit 100. The first sheet 110 may be basically formed in a plate shape having a larger area than the excretory organ in order to reliably receive a large amount of excrement without leakage.

An absorbent material 150 may be added to increase the absorbency of feces.

The absorbent material 150 may be stacked on one surface of the second sheet 120 facing the user. The absorbent material 150 may include materials such as cotton, SAP (Super Absorbtion Polymer), and tissue.

The absorbent material 150 such as cotton is easy to slip on the first sheet 110 made of vinyl. At this time, due to the slip, the cotton particles, SAP particles, and tissue particles constituting the absorbent material 150 are not fixed relative to the first sheet 110 and are shifted in position, so that the absorbent material 150 is empty and the other side of the excretion area is empty. The phenomenon in which the silver absorbent 150 is concentrated may be generated.

The second sheet 120 that is easily bonded to the first sheet 110 of the vinyl material may be used to prevent the positional variation of the absorber 150 particles. For example, the second sheet 120 in contact with the cotton may include a non-woven fabric that passes the excrement and limits the variation in the position of the cotton.

When the absorbent material 150 is provided, the third sheet 130 may be added to prevent the phenomenon that the absorbent material 150 is separated from the second sheet 120.

The third sheet 130 may be laminated on one surface of the absorbent material 150 facing the user, and may include a material through which feces passes. The center of the third sheet 130 covers the absorbent material 150, and an edge of the third sheet 130 may be directly bonded to the first sheet 110 or the second sheet 120.

In the center of the sheet portion 100 including the absorbent material 150, the first sheet 110, the pattern 200, the second sheet 120, as shown in FIG. The absorber 150 and the third sheet 130 may be formed in a stacked structure in order.

The edge of the sheet portion 100 is formed in a structure in which the first sheet 110, the pattern 200, and the second sheet 120 are sequentially stacked as shown in FIG. Can be. A third sheet 130 may be additionally stacked on the second sheet 120 at the edge of the sheet portion 100.

The third sheet 130 may function as a cover for preventing separation of the absorbent material 150 with respect to the first sheet 110 or the second sheet 120. In addition, the third sheet 130 prevents the phenomenon that the cotton particles, SAP particles, and tissue particles constituting the absorbent material 150 are deposited on the user's body or the excrement absorbed by the absorbent material 150 is returned to the user's body. can do.

The absorbent material 150 and the pattern 200 may be formed in the excretion area. The first sheet 110, the second sheet 120, the absorbent material 150, and the third sheet 130 may be formed with a larger area than the excretion area. However, in order to reduce costs, the absorbent material 150 may be formed according to the size of the excretion area. In other words, the absorbent material 150 may be formed with a smaller area than the first sheet 110, the second sheet 120, and the third sheet 130. If the area of the absorbent material 150 is small, the edge of the third sheet 130 can be easily bonded to the edge of the second sheet 120.

According to the above configuration, along the direction from the outside toward the user's body, the sheet portion 100 in which the first sheet 110, the second sheet 120, the absorbent material 150, and the third sheet 130 are sequentially stacked ) May be provided.

At this time, since the second sheet 120, the absorbent material 150, and the third sheet 130 include a material through which the excrement is passed, the excrement excreted in the excretion area by the user of the first sheet 110 facing the user It may be present from one side to the third sheet 130.

The pattern 200 is for detecting excrement discharged to the excretion area, and may be installed in a section from the first sheet 110 to the third sheet 130 where excrement may be present.

The pattern 200 may be printed on one surface of the first sheet 110 facing the second sheet 120. For example, the pattern 200 may include a conductive ink printed or coated on one surface of the first sheet 110 facing the user. When the first sheet 110 includes a material through which a portion of feces passes, the pattern 200 may be formed on the opposite side of the surface facing the user in the first sheet.

The conductive ink includes at least one of materials containing a metal oxide such as carbon and other conductive polymers (conductive material such as carbon, polymer, metal oxide, and PEDOT), carbon, polymer, and metal oxide , Solvent for diluting a conductive material such as PEDOT, water and acetyl corresponding to the solvent of the conductive polymer.

PEDOT is poly(3,4-ethylenedioxythiophene).

If the polymer is largely divided, it can be divided into a performance polymer and a functional polymer. Performance polymers are polymers derived from the properties of polymers and characterized by mechanical or thermal properties. A functional polymer is a polymer in which special properties are expressed according to functional groups present in the polymer, or functional properties are expressed by blending a functional material with the polymer.

Looking at the use of the conductive polymer, the conductive molding material and the conductive film are predominant, and are used in various fields such as for transporting ICs and for transparent electrodes. This field may include techniques for blending polymers with conductivity imparting agents.

The conductive polymer may include polyacetylene, polypyrrole, polythiophene, polyaniline, and the like.

The first sheet 110 may include a transparent material such as polyethylene so that the pattern 200 printed or coated on one surface of the first sheet 110 can be viewed from the other side of the first sheet 110. As a result, as shown in FIG. 1, it is possible to easily grasp the presence or absence of the pattern 200 and the position of the pattern 200 on the other side of the first sheet 110.

Since the pattern 200 is visible on the other side of the first sheet 110, the user can easily align the terminal unit 500 electrically connected to the pattern 200 to the sheet unit 100.

The diaper can be formed larger than the actual excretion area to be worn on the user's body. At this time, in order to improve productivity and wearing comfort, the absorbent material 150 may be provided only in the excretion area k.

Two or more patterns 200 may be provided, and some of the plurality of patterns 200 form a positive (+) pattern 210 to which a sensing signal of the terminal unit 500 is applied, and a plurality of patterns ( The other pattern of 200) may form a negative (-) pattern 220 in which the sensing signal is returned to the terminal unit 500 again.

The terminal unit 500 may be detached from the seat unit 100. Three or more terminals 530 physically contacting the pattern 200 may be formed on the terminal unit 500. Specifically, the number of terminals 530 may be one or more than the number of patterns 200.

The terminal 530 and the pattern 200 may be formed to physically contact at least one terminal to each of two or more patterns 200 spaced apart from each other when the terminal unit 500 is mounted on the sheet unit 100. .

For example, when two patterns 200 spaced apart by a predetermined interval are provided in the sheet unit 100, the terminal unit 500 is provided with two terminals 530 formed at the same interval as the two patterns 200. Can be. In this case, when any one terminal 530 is physically contacted with a specific pattern 200, the remaining terminals 530 may be naturally aligned with other patterns 200 and physically contacted.

The terminal and the pattern 200 may be electrically connected by physical contact between the terminal 530 and the pattern 200.

3 is a block diagram showing the terminal unit 500.

A sensing module 550, a discrimination module 570, a display module 580, a communication module 590, a quantity module 560, etc. may be provided in the terminal unit 500 detachable from the sheet unit 100.

The sensing module 550 may generate a sensing signal for detecting feces and provide a sensing signal to a terminal contacting the pattern 200.

For example, the sensing module 550 applies a sensing signal to a terminal in contact with the positive pattern 210, and a negative signal 220 that passes through the positive pattern 210, the excrement, and the negative pattern 220 in order. It can be received from the terminal in contact with. The sensing module 550 may detect the presence or absence of excrement and the amount of excrement using a detection signal input from a terminal contacting the negative pattern 220.

In order to detect the fine feces present between each pattern 200 and improve the feces detection performance, the first wing 211 protruding toward the negative pattern 220 may be provided in both patterns 210. Similar to the first wing 211, the negative pattern 220 may be provided with a second wing 221 protruding toward the positive pattern 210.

In order to be detachable from the seat unit 100, the terminal unit 500 may be provided with a first detachable unit 510 and a second detachable unit 520 coupled to each other with the sheet unit 100 interposed therebetween.

At this time, the terminal may be installed on the first detachable portion 510 disposed on one side of the first sheet 110 facing the user. The terminal may be physically contacted with the pattern 200 through the second sheet 120 when the terminal unit 500 is mounted on the sheet unit 100.

Since the terminal is disposed on one side of the first sheet 110 facing the user, the phenomenon that an unwanted hole is formed in the first sheet 110 by the terminal can be prevented. As a result, according to the present embodiment, the first sheet 110 may be maintained in a state in which feces cannot pass.

The terminal unit 500 may determine whether there is an abnormality in the seat unit 100 or whether physical contact/alignment between the pattern 200 and the terminal is performed using a plurality of terminals formed in a number larger than the number of the patterns 200.

For example, the terminal unit 500 may be provided with a first terminal 531 and a second terminal 532 that are in contact with one specific pattern 200 among a plurality of patterns 200.

The terminal unit 500 uses a first terminal 531 and a second terminal 532 contacted with one specific pattern 200 to determine the physical characteristics of the specific pattern 200 (570) This can be provided.
The physical property may be either the energization of the specific pattern 200 or the resistance value.

The determination module 570 may determine whether the sheet portion 100 is abnormal using the physical characteristics of the specific pattern 200.

4 is a schematic diagram showing a first terminal 531 and a second terminal 532 contacting a specific pattern 200.

For example, the terminal unit 500 includes a first terminal 531 and a second that are in contact with a specific pattern 200 (negative pattern 220, positive pattern 210) of a plurality of patterns 200 together. Terminal 532 may be provided.

The terminal unit 500, specifically, the determination module 570 may measure the resistance value between the first terminal 531 and the second terminal 532 in physical contact with the specific pattern 200. At this time, the resistance value R measured by the determination module 570 may be a resistance value in a section of the pattern 200 disposed between the first terminal 531 and the second terminal 532.

When the distance between the first terminal 531 and the second terminal 532 is L, the resistance value R measured by the discrimination module 570 may be a resistance value per L length.

The determination module 570 may compare the lookup table including the resistance value per L length and the measured resistance value R. As a result of comparison, if the measured resistance value R satisfies the set value, the determination module 570 may determine that the corresponding pattern 200 and the corresponding sheet portion 100 are normal.

The determination module 570 of the terminal unit 500 may generate a warning signal that guides the abnormality of the sheet unit 100 instead of the detection signal when the measured resistance value R exceeds the set value. If the measured resistance value R exceeds the set value, the excrement may not be detected normally, or an electric shock accident may occur due to overcurrent. According to this embodiment, a warning signal is generated instead of a detection signal that may cause electric shock or the like when an abnormality occurs in the pattern 200, so that an accident of electric shock can be prevented.

The warning signal generated by the determination module 570 may be displayed through the display module 580 of FIG. 3 such as a display, warning light, speaker, and the like.

According to the present exemplary embodiment, it is possible to easily grasp the presence or absence of an abnormality in the sheet portion 100, and to identify the imitative sheet without considering the user's safety or the like.

Meanwhile, the determination module 570 may determine whether an alignment state between each terminal and the pattern 200 or physical contact between each terminal and the pattern 200 occurs.

For example, the first terminal 531 may provide a detection signal to a specific pattern 200 among the plurality of patterns 200. In this case, the second terminal 532 may be formed to contact the specific pattern 200 together with the first terminal 531.

The determination module 570 of the terminal unit 500 uses the second terminal 532 to arrange the alignment between the first terminal 531 and the specific pattern 200 or between the first terminal 531 and the specific pattern 200. Physical contact can be determined.

The first terminal 531 and the second terminal 532 connected to the same specific pattern 200 through which electricity is communicated may be electrically connected by the specific pattern 200.

At this time, the discrimination module 570 applies a discrimination signal to one of the first terminal 531 and the second terminal 532, analyzes the discrimination signal returned to the other one, and then the first terminal 531 and the second terminal 532. It is possible to determine whether or not the electrical connection between the. In this case, the determination signal may be for checking the energization state between the first terminal 531 and the second terminal 532.

When the determination module 570 determines that the first terminal 531 and the second terminal 532 are electrically connected, both the first terminal 531 and the second terminal 532 are normally connected to the specific pattern 200. It can be determined as contacted. The first terminal 531 and the second terminal 532 contacting the same specific pattern 200 together indicate that the first terminal 531 and the second terminal 532 are aligned with the specific pattern 200. Can be.

5 is a schematic diagram showing an alignment state between the pattern 200 and the terminal. 5(a), (b), (c), and (d) show the alignment state of the terminals with respect to the pattern 200, respectively.

When the pattern 200 extends along the first direction ①, each pattern 200 may be formed to be spaced apart from each other in a second direction ② perpendicular to the first direction ①. In this case, the first direction ① may be the longitudinal direction of the sheet portion 100, and the second direction ② may be the width direction of the sheet portion 100.

At least two terminals among three or more terminals provided in the terminal 500 to determine whether the pattern 200 is abnormal, determine whether there is contact between the terminal and the pattern 200, and determine the alignment state between the terminal and the pattern 200, eg For example, the first terminal 531 and the second terminal 532 may be connected to any one specific pattern 200 among the plurality of patterns 200.

When a total of four terminals of the first terminal 531, the second terminal 532, the third terminal 533, and the fourth terminal 534 are provided in the terminal unit 500, the first terminal 531 and the first terminal The two terminals 532 may be formed to contact both patterns 210 together. The third terminal 533 and the fourth terminal 534 may be formed to contact the negative pattern 220 together. When the first terminal 531 and the second terminal 532 are aligned with the positive pattern 210, the first terminal is such that the third terminal 533 and the fourth terminal 534 are aligned with the negative pattern 220 The spacing between the 531 and the third terminal 533 and the spacing between the second terminal 532 and the fourth terminal 534 are preferably the same as the spacing between the positive pattern 210 and the negative pattern 220.

In this case, the first terminal 531 or the second terminal 532 may be an element that applies a sensing signal to the pattern 200. When excrement is present across the positive pattern 210 and the negative pattern 220, the excrement may function as a conductor that electrically connects the positive pattern 210 and the negative pattern 220. The third terminal 533 or the fourth terminal 534 may provide a detection signal transmitted to the sound pattern 220 to the terminal 500 by riding the feces.

The sensing module 550 may analyze the detection signal provided from the third terminal 533 or the fourth terminal 534 to determine the presence or absence of feces or the amount of feces.

When feces are detected, the sensing module 550 may display the fact of the feces or the amount of feces through the display module 580.

For example, the sensing module 550 may control the display module 580 such that different colors are displayed according to the detected amount of feces.

The plurality of terminals that are in contact with one pattern 200 together, for example, the first terminal 531 and the second terminal 532 may be formed to be spaced apart from each other in the second direction ② as shown in FIG. 5.

The first terminal 531 and the second terminal 532 may be formed at intervals equal to or less than the width of the specific pattern 200 in the second direction ② in order to be able to contact one and the same specific pattern 200 together. . According to this embodiment, as shown in (a) of FIG. 5, the first terminal 531 and the second terminal 532 are in contact with both patterns 210, and the third terminal 533 and the fourth terminal 534 ) May be in contact with the negative pattern 220.

On the other hand, due to the alignment error, as shown in (b) and (c) of FIG. 5, only one of the first terminal 531 and the second terminal 532 is in contact with both patterns 210, and the third terminal 533 and Only one of the four terminals 534 may contact the sound pattern 220.

The determination signal provided to the first terminal 531 by the terminal 500 may be applied to the specific pattern 200 through the first terminal 531. The determination signal may be received through the specific pattern 200 to the second terminal 532. The discrimination module may additionally provide a discrimination signal through the third terminal 533. The discrimination signal provided to the third terminal may be received through the negative pattern to the fourth terminal.

The determination module 570 of the terminal unit 500 determines the physical characteristics of the specific pattern 200 using the determination signal received by the second terminal 532, or the first terminal 531 and the specific pattern 200 It is possible to determine whether or not there is physical contact with the liver. The terminal 500 may determine whether to generate a detection signal according to a determination result of physical characteristics or a determination result of physical contact.

In the case of (b) and (c) of FIG. 5, since one terminal is connected to each pattern 200, a normal operation of the detection signal is possible. Nevertheless, the determination module 570 may determine the alignment state or the contact state between the terminal and the pattern 200 as defective. The detection signal may not be generated due to the defect determination of the determination module 570.

As a result, in the case of (b) or (c) of FIG. 5, the user needs to correct the mounting state of the terminal unit 500 with respect to the seat unit 100 to make the state as shown in FIG. 5(a). As a result, the user has to suffer the inconvenience of precisely aligning the terminal unit 500 and the sheet unit 100 so as to be in a state as shown in FIG. 5(a).

In order to reduce the inconvenience of the user, the first terminal 531 and the second terminal 532 are arranged to be spaced apart from each other along the first direction ① as shown in FIG. Can be placed on.

According to this embodiment, even if the alignment state between the terminal unit 500 and the sheet unit 100 is somewhat disturbed along the second direction ②, the first terminal 531 and the second terminal 532 are both patterns 210 ), and the third terminal 533 and the fourth terminal 534 may be in contact with the negative pattern 220. As a result, according to the embodiment illustrated in FIG. 5D, precision required for alignment between the terminal unit 500 and the sheet unit 100 may be relaxed.

3, the communication module 590 may wirelessly communicate with the server. For example, the communication module 590 may communicate with a server through a wireless communication network such as ZigBee, Wi-Fi, Bluetooth. In consideration of the communication distance, the communication module 590 preferably uses a Zigbee network.

When feces are detected by the sensing module 550, the communication module 590 may generate a first notification message including identification information of the terminal unit 500 and the first visual information on which the feces are detected, and transmit it to the server. .

The server receiving the first notification message may identify a user wearing the terminal unit 500 using the identification information of the terminal unit 500. The server may manage the state of excretion of the identified user using the first visual information on which the excrement has been detected.

Meanwhile, the terminal unit 500 may be provided with a quantity module 560 for counting the quantity of the replaced sheet unit 100 whenever the sheet unit 100 is replaced.

The communication module 590 includes the identification information of the terminal unit 500, the quantity information of the sheet unit 100 replaced with respect to the terminal unit 500, and the second time information in which the sheet unit 100 is replaced. Notification messages can be sent to the server.

The quantity information of the replaced sheet unit 100 may be used to establish policies such as calculating the amount of benefits such as medical insurance. The second visual information may be used to grasp the user's habit of replacing the sheet portion 100. In some cases, the second visual information may be used to detect an illegal act of replacing the sheet portion 100 for an abnormal claim of medical insurance.

The sensing module may check whether the second determination signal is obtained from the other of the third terminal and the fourth terminal.

The detection module may generate a detection signal capable of detecting feces only when both the first and second determination signals are obtained. According to this embodiment, all four terminals should be aligned and contacted with the pattern, but a sensing signal may be generated. Therefore, a phenomenon in which a detection signal is unnecessarily generated can be prevented.

The sensing module may apply the sensing signal to at least one of the first terminal and the second terminal. The sensing module may monitor a sensing signal obtained from at least one of the third terminal and the fourth terminal.

The sensing module may detect the presence or absence of feces or the amount of feces through monitoring the detection signal.

The sensing module may operate in a sleep mode in which a discrimination signal for determining whether the terminal is in contact with the pattern is applied to the terminal when power is applied.

The sensing module may operate in an on mode in which a sensing signal is applied to the terminal when it is determined that the terminal contacts the pattern during operation in the sleep mode.

At this time, the discrimination signal may have a lower power value than the detection signal. The sensing module may be operated by a battery having a limited charge provided in the terminal unit. In order to maximize the operation period of the detection module, it is preferable that the discrimination signal and the detection signal are generated in real time and applied to the terminal instead of being generated in real time.

The discrimination signal may determine whether a normal seat portion is mounted on the terminal portion. According to the discrimination signal, the detection signal is not generated even if the user connects the terminal using a finger, a copy sheet, or other physical reaction. Therefore, since the use of the normal sheet portion is forced, it is possible to induce the user to use the normal sheet portion that satisfies the setting criteria such as absorption rate. In addition, it is difficult to manipulate the replacement quantity of the seat portion for abnormal insurance premiums.

The discrimination signal may be generated when a battery is newly installed in the terminal portion or a power switch is turned on to determine the seat portion that may not be mounted. As a result, a discrimination signal may be generated when only power is applied to the terminal. At this time, since the power value of the discrimination signal is lower than the detection signal, unnecessary power consumption can be minimized.
