Description

Silver mat assembly for dementia prevention {SILVER MAT ASSEMBLY TO PREVENT DEMENTIA}

The present invention relates to a silver mat assembly for dementia prevention, a mat having a game area for at least two dementia prevention games, and a simple pen that not only analyzes codes but also outputs various sounds necessary for game progress without a separate smartphone It is to provide a silver mat assembly, that is, a silver mat assembly, that can perform dementia prevention for the elderly in a fun and colorful way without being boring in a state of being composed of one combination structure.

Currently, Korea is facing an unprecedentedly fast aging rate, and as the elderly population rapidly increases, the problems that need to be solved such as dementia, depression, loneliness, and loneliness are related to silver care.

As can be seen from the social distancing situation caused by the Corona 19 virus, which continues to be prevalent in early 2021, there is a problem that the elderly, who need to be taken care of first, are isolated from society because their immunity is weak.

There are a total of 206 bones in the human body, of which the hand, which has many joints and neural networks, sends and receives abundant signals to and from the brain. Since it is activated in response, hand movements such as handwriting, sewing, woodworking, and playing musical instruments are a good way to revitalize a tired brain. As the prefrontal cortex, which is involved in situational judgment and emotion regulation, is activated in the brain, the secretion of hormones that respond to stress decreases, thereby stabilizing the mood.

Currently, a well-known method for dementia prevention is to output a dementia prevention program on a large display and visually follow it along with the rhythm, or a group woven on a mat provided in a place such as a village senior welfare center. There are ways to activate the brain by moving the body according to the dementia prevention program.

However, these two methods are difficult for elderly people with limited mobility to participate in the first place, and there is a problem that they can be useless in the social distancing situation caused by Corona 19 because they have to do it mainly outside the house as a group.

Therefore, if the dementia prevention function is given to the mat, which is a familiar daily tool used by the elderly, not only can it be used conveniently without a separate tool, but it can also provide an active base that can be actively utilized even when specific movement is inconvenient.

The prior art related to dementia prevention education implemented based on the mat has been published. Among them, the system in which the dementia prevention program, which is Korean Patent Laid-Open No. 10-2016-0121215, interlocks the cushion and functional mat with the tactile tool, is the seat layer. , Mats comprising an image layer on which an image is printed on the sheet layer, an acoustic or audio optical index layer corresponding thereto, and a damage prevention layer protecting the optical index layer; a sensing unit for optically sensing the optical index; a data storage unit for storing sound or voice data corresponding to the sensed optical index; a sound source generating unit for generating a sound source of the corresponding sound or audio data; a sound source processing unit that receives the sound source or sound generated by the sound source generator, converts it to analog, and amplifies; and an output unit for outputting the processed sound source; including, touching the mat with hands and feet to perform brain health with acupressure effect.

However, according to the above technology, although the dementia prevention function is grafted onto the mat, the physical exercise method using the pressure of the hands and feet not only emphasizes the exercise function of the hands and feet rather than the prevention of dementia, but also electric devices such as sensors and thermostats inside the mat Also, there is a problem that the original function of the mat that can be comfortably spread and used in daily life cannot be used, and at the same time, malfunction can occur frequently when it comes into contact with water.

Among the mat-based technologies, if the OID code and the pen that can recognize it, which are well-known for education, can be used as a kind of play tool that the elderly can use conveniently at home, it can be used as a play tool to prevent dementia as well as depression. It is expected to create a healthy dementia prevention environment where people can play safely without risk of virus infection even during social isolation due to COVID-19.

The present invention has been devised to overcome the problems of the above technology, and is based on a combination of a mat printed with an OID code and a pen capable of recognizing it, without a separate tool that may be difficult to operate, such as a smartphone, conveniently interlocked. Its main purpose is to provide a silver mat assembly that can prevent dementia as well as depression while having fun without feeling bored by providing various dementia prevention education in the form of a game.

Another object of the present invention is to provide a dementia prevention game in various types with various difficulty levels to further ensure the fun of the elderly.

Another object of the present invention is to secure a safe use environment for the elderly by strengthening the anti-slip function of the mat.

A further object of the present invention is to provide a cleaning means capable of solving problems such as virus infection in an environment where several people gather, such as a welfare facility for the elderly.

In order to achieve the above object, a silver mat assembly for dementia prevention according to the present invention is provided with a game area including at least two dementia prevention games on the upper surface, and an image and an OID code are printed so that each game area includes an image and an OID code. silver matte; A speaker, a game database storing attribute information of the OID code included in the image, a game guide module for outputting a guide sound including the type and rule of the dementia prevention game to the user through the speaker, and a tip ) provided in a code recognition sensor for sequentially recognizing the OID code, and a code analysis module for determining the correctness of the OID code sequentially recognized by the code recognition sensor based on the attribute information of the OID code; and a pen including a sound output module for differentially outputting an alarm sound through the speaker according to a determination result of noon for the attribute information of the OID code.

In addition, the dementia prevention game includes a search for the same image in which a plurality of picture images are placed in a first game area, which is one of the plurality of game areas, to find the same picture image, and another one of the plurality of game areas. It consists of a related image finding game in which a plurality of picture images are arranged in a second game area and a picture image related to each other is found, and the code analysis module is for the same image finding game, and is included in each of the plurality of picture images A function of performing a judgment corresponding to positive in the same picture image and false in different picture images when sequentially recognizing the OID code, and for the related image search game, a plurality of pictures When the OID codes included in each image are sequentially recognized, it is characterized in that it includes a function of performing a judgment corresponding to a positive (positive) in a picture image associated with each other and a false (誤) in a different picture image.

1 is a conceptual diagram illustrating a basic configuration relationship of a silver mat assembly for dementia prevention according to the present invention.

The silver mat assembly of the present invention is a combination of a silver mat 100 and a pen 200 as shown in FIG. based on what has been done.

In other words, the known OID mat system often has a separate mobile application installed on the smartphone while being linked with the smartphone. Many pointed out that there is a high risk of causing inconvenience to the elderly to prevent dementia.

Therefore, the present invention is also possible for the elderly who are accustomed to operating a smartphone to be linked with a smartphone installed with a mobile application for dementia prevention education, but as shown in FIG. 1, a silver mat 100 and a pen 200 are simple It provides the characteristics that can perform dementia prevention education through one constitutive relationship.

2 is a plan view illustrating a state in which four game areas are printed on the silver mat of the present invention, and FIG. 3 is a conceptual diagram illustrating a state in which an OID code is printed on the silver mat of the present invention.

The silver mat 100 of the present invention has a shape and material like a well-known mat, and a plurality of game areas 110 are formed on the upper surface (surface), and various images 111 are formed on each game area 110 . and OID codes are printed. In the present invention, this mat is named 'silver mat' (100) to reflect that the elderly (silver) are the main users.

Although the figure illustrates a structure in which the silver mat 100 has a rectangular cross-sectional shape, it is not necessarily limited thereto and may take various shapes such as a circular cross-section or an elliptical cross-section. In addition, the size of the silver mat 100 can be made to the extent that it can be seated on the top surface of a desk made of a normal table size, or can be made in various sizes that can be spread or spread on the floor to be used as a general mat.

In addition, the material of the silver mat 100 is also various to apply a variety of known materials, for example made of PVC, TPU (thermoplastic polyurethane), etc. to ensure durability while providing constant cushioning and elasticity, or to be described later on the upper surface. It is also possible to have a double structure in which a surface layer made of a synthetic resin that is not easily erased when the game area 110 is printed, and a soft material such as artificial fibers are laminated on the bottom of the surface layer.

In addition, in order to guarantee the durability and elasticity of the silver mat 100 as well as the anti-slip function, a structure in which a base and a functional layer (anti-slip layer) laminated under the base are laminated may be presented, which will be described in detail below. .

On the upper surface (surface) of the silver mat 100, a so-called area for enjoying at least two dementia prevention games is formed (printed), which is referred to as a 'game area' 110 in the present invention. That is, in the present invention, the main goal is to enable the elderly to prevent dementia while naturally enjoying the dementia prevention game in a naturally enjoyable and comfortable atmosphere through games or play methods. are taking

At least two game areas 110 of the present invention are basically included on the upper surface of the silver mat 100, but in FIGS. 1 to 2, a total of four game areas 110 are exemplified.

As shown in FIGS. 1 and 2 , when four game areas 110 are formed in a rectangular silver mat 100 , the game areas 110 can be arranged in a 2*2 matrix structure. The present invention is not limited thereto, and it is possible to arrange the game area 110 in various matrix structures according to the shape and length/width of the silver mat 100 .

A plurality of images 111 in the form of a grid or tile are formed in the game area 110 . Although the drawing shows that the image 111 is formed in a rectangular shape, the image 111 is not limited thereto and may be formed in various shapes such as a circle or a triangle.

In this image 111, various pictures reflecting the rules for the dementia prevention game are drawn, and an OID code is printed for each image 111.

An OID (Object IDentifier) code is an object identifier that gives a name to any type of object, concept, or thing that requires a persistent name. . That is, the information contained in the OID code is more important than the format of the code itself. In the present invention, information having a specific meaning of the OID code is referred to as 'attribute information'. Since such an OID code is a well-known technique in the technical field for a mat to which the OID code is applied, a detailed description of the principle will be omitted.

Referring to FIG. 3 , the OID code printed for each image 111 may have different attribute information. In this case, as will be described later, for example, dementia prevention such as a game to find the same image 111 (or related images, etc.) Among the images 111 printed on the game area for the game, it is also possible to print an OID code having the same attribute information on a pair of images 111 composed of the same or related pictures, or OID code attribute information Although different, it is also possible to analyze and process the attribute information of the OID code printed on the pair of images 111 in the same meaning in the game database 250 and the code analysis module 270, which will be described later.

4 is a perspective view showing a schematic internal structure of the pen of the present invention.

As can be seen from FIG. 4 , the pen 200 of the present invention is provided with a button 211 capable of turning on/off power or performing other operations on the outer circumferential surface of the housing enclosing the internal components. Components, specifically, a processor unit (CPU) 220 and RAM/ROM (ROM) 221 , a communication chip 222 , a battery 230 , and components such as a speaker 240 are included.

That is, it is possible to provide a writing function like the known pen of the present invention, but it is not necessarily limited to providing a writing function. It is provided with an electronic component for performing detailed functions to be described later in a state similar to a pen. can be said to be the key.

The processor unit 220 is a kind of controller that performs a function of controlling the output of various sounds through the speaker 240 by analyzing the attribute information of the OID code received through the game database. In this case, the controller of the present invention is the processor unit 220 ) and a RAM 221/ROM in which an OID code transmission and analysis program is embedded.

That is, in the controller, a program that can be executed in the processor unit on a hardware basis having a memory or storage means such as the processor unit 220 and the RAM 221 / ROM, that is, software is installed and this software can be executed. A series of specific configurations of 'module', 'part', and 'interface' will be described later as structural units.

In other words, the controller includes a RAM 221 (Random Access Memory) and ROM (Read-Only Memory, not shown) that temporarily and/or permanently store signals (or data) processed therein; It may include a processor unit 220 .

Specifically, the processor unit may include one or more cores and a graphic processing unit (not shown) and/or a connection path (eg, a bus, etc.) for transmitting and receiving signals to and from other components, and the RAM Programs (one or more instructions) for execution and control of modules or units to be described later may be stored in a memory such as 221/ROM. Programs stored in the memory may be divided into a plurality of modules according to functions.

The steps of a method or algorithm described in relation to an embodiment of the present invention may be implemented directly in hardware, as a software module executed by hardware, or by a combination thereof. A software module may contain random access memory (RAM), read only memory (ROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), flash memory, hard disk, removable disk, CD-ROM, or It may reside in any type of computer-readable recording medium well known in the art to which the present invention pertains.

The configuration of these 'modules' or 'parts' or 'interfaces' is installed and stored in the storage means of the controller, and software or hardware such as FPGA or ASIC executed via the processor unit 220 and RAM 221 / ROM means the work composition of That is, the configuration of 'module', 'unit', and 'interface' is not limited to hardware, and may be configured to be in an addressable storage medium or may be configured to reproduce one or more processors.

The functions provided by these 'modules' or 'units' or 'interfaces' may be combined into a smaller number of components and 'units' or 'modules' or additional components and 'units' or 'modules'. can be further separated.

Hereinafter, a detailed configuration and function of the pen 200 of the present invention will be described with a focus on such a controller.

First, a code recognition sensor 210 that reads and recognizes an OID code is installed at a tip, which is an end (the tip of the lower end) of the pen 200 , and outputs various sounds to be described later on one side of the pen 200 . and a speaker 240 that does. In this case, the housing of the pen 200 may be formed in various shapes such as characters.

In this state, based on the above-described controller, the pen 200 of the present invention includes a game database 250 , a game guide module 260 , a code analysis module 270 , and a sound output module 280 .

The game database 250 basically stores attribute information about the OID code included in the image 111 of each game area. That is, when the code recognition sensor 210 recognizes the OID code, the game database 250 may serve as a basis for informing the code analysis module 270 of the meaning of the corresponding OID code, that is, the attribute information, which will be described later. have.

Furthermore, the game database 250 stores the rules of each dementia prevention game or accessory information for detailed analysis in the code analysis module 270 to be described later, as well as the game guide module 260 or the sound output module 280 ) plays the role of saving various sounds output from the file format.

The game guide module 260 performs a function of outputting a guide sound including the type and rule of the dementia prevention game to the user through the speaker 240 . For example, if the user is guided to the same image search game, it can be guided as "Choose two pictures with the same shape." Choose a picture like ". In response to such detailed dementia prevention game rules, the game database 250 provides detailed information that can be analyzed by the code analysis module 270 to the code analysis module 270 through which the code analysis module 270 provides detailed information. It is possible to perform analysis judgments corresponding to the normal dementia prevention game rules.

The code analysis module 270 receives the attribute information for the OID code recognized by the code recognition sensor 210 from the game database 250, and the code recognition sensor 210 sequentially recognizes the attribute information based on this attribute information. It performs the function of determining the noon of the OID code.

Here, the sequential recognition means that the dementia prevention game of the present invention has a main purpose to find the same, related/continuous images, etc., and whether they are the same or related/continuous, that is, the noon judgment is one OID code This means that it is assumed that the code recognition sensor 210 recognizes at least two OID codes in time series (sequentially according to time flow).

As described above, sequentially recognizing two OID codes and judging whether the order is right or wrong is called noon judgment, and various types of dementia prevention games in which noon judgment is possible may exist.

To explain the dementia prevention game as an example, place multiple fruit pictures in the game area, but place 2 identical fruits to find them, 1 by 1 like 1,2,3,4,5,6,7.. It may consist of various rules and images, such as a game in which consecutive numbers are sequentially searched to increase, and in response, the code analysis module 270 indicates the meaning of the attribute information of the OID code first transmitted from the code recognition sensor 210 When is 'apple', if the meaning of the attribute information of the second transmitted OID code is 'apple', it is judged as positive, and if it is 'tangerine' rather than 'apple', it can be judged as false. have.

The sound output module 280 has a function of differentially outputting an alarm sound through the speaker 240 according to the result of the determination of noon for the attribute information of the OID code in the code analysis module 270 described above. carry out

To explain the previous example, in the same image finding game in which the user has to press two images sequentially through the tip of the pen 200, when the user presses the picture images for apple-apple sequentially, it is judged as positive Thus, the sound output module 280 outputs sounds such as “You did a good job” and “That’s right. You did a good job.” When the apple-tangerine is pressed, it is judged as “O” and outputs “I’m sorry” or “ When a new OID code is inputted in response to outputting a guide message giving one more opportunity, such as "Please press it again", the code analysis module 270 may determine noon again.

In particular, the dementia prevention game of the present invention consists of at least two types, for example, one is a game for finding the same picture/image and the other is a continuous number game, so that the user can enjoy dementia prevention without feeling bored. Make it an important purpose to be able to

At this time, a button for selecting any one of at least two dementia prevention games is separately provided on the pen 200 or a separate game selection image is formed around the game area 110 on the silver mat 100 and then this game It is possible to recognize the start of a specific dementia prevention game in the code analysis module 270 when the user presses the OID code in which attribute information indicating the start of the game is stored on the selected image.

In summary, the silver mat assembly of the present invention enables the education specialized in dementia prevention to be conducted in at least two different game methods, so that you can enjoy the same experience at home without having to visit the dementia prevention center or repeat only one game tediously. It provides the characteristics of being able to receive simple and diverse dementia prevention education in a comfortable environment.

5 is a flowchart illustrating a noon determination process for the same image search game, and FIG. 6 is a flowchart illustrating a noon determination process for a related image search game.

As mentioned above, the dementia prevention game provided by the present invention is provided in at least two types. The functions of the four dementia prevention games shown in FIGS. 1 and 2 and the detailed configuration of the pen 200 corresponding thereto will be described in detail. do.

First, referring to FIG. 5 , it can be seen that the noon determination process for the same image search game is shown.

The dementia prevention game according to FIG. 5 is a 'same image finding game', a game in which a plurality of images 111 (pictures or picture images) are placed in one of the plurality of game areas to find the same picture image. it means.

Specifically, the user presses a specific button of the pen 200 or presses a game selection image provided on one side of the game area to start the game, and then draws the second picture image corresponding to 'magpie' on the tip of the pen 200. When instructed or pressed, the code recognition sensor 210 recognizes the OID code (00012) of this figure image, and the code analysis module 270 stores the OID code (00012) as 'magpie' in the game database 250 will be delivered from

Thereafter, when the user directs or presses the tip of the pen 200 to the 4th picture image, which is the same picture as the 2nd picture, the code recognition sensor 210 recognizes the OID code (00024) of the picture image and the code analysis module 270 The game database 250 receives attribute information in which this OID code (00024) is stored as 'magpie'.

At this time, the code analysis module 270 analyzes that both the first OID code 00012 and the second OID code 00024 are 'magpies' based on each attribute information, and determines that they are positive.

Thereafter, the sound output module 280 may output an alarm sound having the meaning of a correct answer. If the user selects No. 3 instead of No. 4 as the second picture image, the code analysis module 270 performs a determination corresponding to an error by the above-described process, and the sound output module 280 in response thereto. outputs an alarm sound with the meaning of incorrect answer.

6 is a diagram illustrating an analysis process of a so-called 'relationship image finding game' in which a plurality of picture images are arranged in a game area for the dementia prevention game, and picture images related to each other are found.

If the user selects the game of finding related images, then selects the 2nd image and sequentially selects the 3rd image, the code analysis module shows the OID code 00156 for the 2nd image and the OID code for the 3rd image. In recognizing 00179, the game database 250 stores these two attribute information as being correlated, so that the code analysis module 270 determines them to be correlated, that is, determines that they are positive, Accordingly, the sound output module 280 outputs an alarm sound having the meaning of the correct answer.

On the other hand, since the first picture image 'car' and the fourth picture image 'wheel' are also correlated images 111, the game database 250 stores attribute information indicating that there is a correlation even with respect to the combination of these OID codes. Thus, the code analysis standard of the code analysis module 270 may be presented.

At this time, an area in which several images 111 for the 'same image search game' of FIG. 5 are stored is referred to as a first game area, and an area where several images 111 for the 'related image search game' of FIG. 6 are stored Referring to as the second game area, the first and second game areas are formed in a state separate from each other on the mat. Of course, the two games to be described later are also formed of a total of four game areas 110 as a third game area image and a fourth game area image, or two dementia prevention games including two dementia prevention games to be described later. It may be selected and displayed as the first and second game areas.

That is, in the dementia prevention game of the present invention, at least two of the four dementia prevention games are selected, and a plurality of detailed images 111 thereof can be displayed on the silver mat 100 in mutually separated areas. .

Although not shown in the drawings, another dementia prevention game of the present invention, 'number game,' is a game in which a user finds consecutive numbers in a state in which a plurality of number images are arranged in the above-described first game area. When the code analysis module 270 sequentially recognizes the OID code included in each of a plurality of number images, it corresponds to a positive number image recognized as a continuous number, and a negative number to a number image recognized as a discontinuous number image. make a judgment

In addition, the 'identical picture finding game' is a game to find a picture image in which the first syllable has the same pronunciation among picture images consisting of, for example, two syllables, for example, 'apple', 'tangerine', 'lion'. , when four picture images of 'tiger' are presented, 'apple' and 'lion' have the same pronunciation of the first syllable, so it can be stored in the game database 250 as having correlated attribute information, and the code analysis module ( 270) shows that when the OID code included in each of a plurality of picture images is sequentially recognized, the picture image with the same pronunciation of a specific syllable is positive, and the picture image that has a different pronunciation of a specific syllable is recognized as wrong. Appropriate judgments may be made. This match game game will have a higher level of difficulty than other dementia prevention games.

As such, the present invention provides a variety of dementia prevention games, and by providing a difference in difficulty from each other, users can add concentration according to the dementia prevention game, thereby preventing the problem that the dementia prevention game is uniformly progressed or the prevention effect is weak. provides the characteristics.

As described above, the silver mat 100 of the present invention can be made in various sizes while being placed on a desk or floor. In particular, when placed on the floor or desk, it slides easily, thereby avoiding the problem of injury to the user sitting on it. There may be a need to prevent

To this end, the silver mat 100 of the present invention can be composed of a double layer of a base and an anti-slip layer.

The base plays the same role as the main plate on which the game area 110, the image 111, and the OID code are printed on the upper surface, and may be made of, for example, a synthetic resin series such as PVC or thermoplastic polyurethane (TPU). This base supports the anti-slip layer, which will be described later, and plays a role in basically securing impact resistance through its own elastic function.

The anti-slip layer is a plate-shaped body laminated under (bottom surface) of the above-described base, and takes a mixed configuration of ethylene vinyl acetate (EVA) and a functional auxiliary agent.

Ethylene vinyl acetate (EVA) is a copolymer of an ethylene monomer and a vinyl acetate (VA) monomer, that is, a material produced by polymerization of the two monomers together. , stress crack resistance, good ozone resistance, and excellent adhesion and workability. In particular, it is possible to combine a shock absorbing function with the function of acting as an anti-slip.

The functional aid is added to add an additional function to ethylene vinyl acetate, which acts as an anti-slip agent, and basically includes chloroprene rubber.

Chloroprene rubber is a synthetic rubber made by polymerizing chloroprene, and is known to have elasticity and anti-slip functions as well as sound-absorbing properties.

Such an anti-slip layer is formed by placing chloroprene rubber on the bottom of the base and then placing ethylene vinyl acetate (EVA) under it, or using a layer made of a mixture of ethylene vinyl acetate (EVA) and chloroprene rubber. It is possible to arrange it on the bottom.

In particular, the present inventors found that the anti-slip layer consists of 40 to 50 parts by weight of a functional auxiliary containing Chloroprene Rubber and 50 to 60 parts by weight of ethylene vinyl acetate (EVA) as a result of experiments over several trials and errors. And it has been found that noise absorption and anti-slip functions can be performed more smoothly.

In summary, by implementing the silver mat 100 as a base and an anti-slip layer (the anti-slip layer may have a one- to two-layer structure) having the above-described structure and composition, shock and noise absorption as well as an anti-slip role are strengthened Therefore, it is possible to not only guarantee the safety of users, especially the elderly, but also to prevent the problem of easily turning off or tearing the silver mat 100 in the process of pressing the silver mat with the pen 200 several times. .

Furthermore, the functional auxiliary agent containing chloroprene rubber is a first solution preparation step, a filtration step, a first material obtaining step, a tertiary solution preparing step, a second material obtaining step in order to further enhance the above-described impact resistance and durability. , it is possible to manufacture through a composite completion step.

First, the first solution preparation step is dimethylformamide (N,N'-Dimethylformamide) 75 to 90 parts by weight, chloroprene rubber (Chloroprene Rubber) 10 to 30 parts by weight, chlorosulfonated polyethylene (chlorosulphonated polyethylene) 5 to 15 It is a process of preparing a first solution by mixing 1 to 10 parts by weight of sodium azide and then heating at 80 to 120° C. for 8 to 15 hours, and the filtration step is 20 to 30 parts by weight of the first solution. It is a process of removing residues by filtration after cooling to °C. After the filtration process, only the solution from which the residues are removed exists.

Here, chloroprene rubber has been previously described, and chlorosulfonated polyethylene is a synthetic rubber made by reacting polyethylene with chlorine and sulfurous acid gas to change it into a vulcanizable elastomer. This chloroprene rubber can be said to be a rubber that chlorosulfonated polyethylene has a chlorine group (-Cl) as a functional group.

Sodium azide serves to provide an azide group to chlorosulfonated polyethylene, and this reaction may proceed in dimethylformamide as a solvent. That is, sodium azide can be substituted with an azide group by providing an _{azide group (N 3 ) to the chlorosulfonated polyethylene.}

In addition, since chloroprene rubber has excellent weather resistance, chemical resistance, and flame retardancy, and chlorosulfonated polyethylene has excellent ozone resistance, heat resistance and durability, it can help improve the durability of the anti-slip layer as a result.

After that, the step of obtaining the first material is a process of preparing a second solution by mixing 80 to 95 parts by weight of water and 5 to 20 parts by weight of the filtered first solution, and then filtering the second solution to obtain the first material as a precipitate. , is a process of obtaining a primary material, which is a solid precipitate, by precipitating the primary solution in an excess of water, wherein the primary material is chloroprene rubber and chlorosulfonated polyethylene substituted with functional groups.

Next, the tertiary solution preparation step is a process of preparing a tertiary solution by mixing 85 to 90 parts by weight of tetrahydrofuran and 5 to 15 parts by weight of the primary material, and mixing the primary material in excess tetrahydrofuran By doing so, impurities and unreacted substances in the solution can be removed.

After that, the secondary material obtaining step is a process of preparing a fourth solution by mixing 80 to 90 parts by weight of methanol and 5 to 15 parts by weight of the tertiary solution, and then filtering the fourth solution to obtain a secondary material as a precipitate, the complex The completion step is a process of vacuum-drying the secondary material for 20 to 30 hours to complete the composite.

Here, it is a process of purifying the modified chloroprene rubber and chlorosulfonated polyethylene by re-precipitating the tertiary solution in excess methanol, through which a complex with high purity can be completed.

In summary, the functional auxiliary agent manufactured through this process is included in the silver mat 100 (precisely an anti-slip layer) to provide an excellent elastic restoring force and a role of strengthening mechanical properties such as impact resistance and abrasion resistance.

Furthermore, when the silver mat 100 of the present invention is placed in a shared facility such as a nursing home, hygiene problems may arise while using it by several people, and in particular, it may cause concerns about the corona virus infection that is prevalent until 2021. Therefore, there is a need to easily clean the silver mat 100 to ensure hygiene.

Therefore, the pen 200 of the present invention additionally includes a detergent tank storing a detergent and a spraying unit in addition to the above-described configuration, so that the silver mat 100 is conveniently sprayed with a detergent before and after use of the silver mat 100 and then gauze or gauze. It is possible to maintain the cleanliness of the silver mat 100 by rubbing it with a tissue.

Specifically, the detergent tank stores a detergent with a disinfecting function, and an inlet connected to the detergent tank is provided to secure the convenience of filling the detergent, and this inlet is opened or closed or connected to an external detergent storage container and conveniently stored in the detergent tank. It provides a base for filling the cleaning agent.

In this case, the detergent means a liquid substance having a cleaning function as well as a disinfecting function, and may be made of, for example, a known surfactant or a mixture of this surfactant and ethyl alcohol (ethanol) or ethyl alcohol and water.

The spray unit includes a manipulation unit, a spray nozzle, and a spray pump, and the manipulation unit is a part that a user manipulates for a spray operation, and may be made of, for example, a trigger or a push button in a known spray. The injection pump delivers the cleaning agent stored in the cleaning agent tank to the injection nozzle through the injection path by the operation of this operation unit, and then ejects the cleaning agent to the outside of the injection nozzle. At this time, the spray nozzle is formed at a position deviated from the tip where the code recognition sensor 210 is installed, or is installed at the end of the spray extension path that protrudes for a certain length to the outside of the housing surrounding the pen 200 to provide the code recognition sensor 210 It is possible to be formed so as not to interfere with its cognitive function.

Since such a detergent tank and the spraying unit are similar to the structure in which the currently well-known spray-type spray barrel has a handle for spraying, separate drawings or descriptions will be omitted.

According to the cleaning agent spraying structure of the pen 200 as described above, the user sprays the cleaning agent onto the mat through the control unit of the pen 200 before using it, and then wipes the silver mat 100 with a separate tissue paper, or wipes the silver mat 100 with a tissue paper. By wiping the pen 200 with a tissue after spraying the detergent, it is possible to provide a feature capable of ensuring a clean use environment as well as virus prevention.
As described so far, the configuration and operation of the silver mat assembly for dementia prevention according to the present invention are expressed in the above description and drawings, but this is merely an example and the spirit of the present invention is not limited to the above description and drawings. , of course, various changes and modifications are possible without departing from the technical spirit of the present invention.
