Description

TECHNICAL FIELD [0001] The present invention relates to a smart mat system for preventing the onset of a disease and a dangerous situation through recognition of the status of a subject,

When a patient living in a nursing care facility or a home or an elderly patient who is uncomfortable in bed lies in the same posture for more than a certain period of time, pressure data is applied to the patient's body by a sensor installed on the bed.

Based on this, the bed automatically changes the posture of the subject and informs the manager or the caregiver to provide the service according to the condition of the subject.

Also, the time and contents of the services performed by the caregiver are automatically transferred to the system and recorded.

Also, in case of an emergency, inform the person in charge immediately so that emergency situation can be dealt with appropriately.

The present invention relates to a smart mat system for preventing diseases and preventing dangerous situations by recognizing the status of a supervisor who is an IoT-based smart healthcare system that helps provide medical care services.

According to the National Aging Index of the National Statistical Office (NSO) in 2014, rapid aging has become a social issue, increasing by 119.1% in 2020, 145.9% in 2024, 177.8% in 2028 and 288.6% in 2040.

As the Korean society is rapidly aging, the interest in elderly people including elderly people and dementia patients is increasing rapidly, and problems related to the protection and treatment of them are becoming social problems. The rapid aging of the silver industry is foreshadowing rapid growth.

In particular, the establishment of specialized medical institutions and nursing homes for the elderly has been increasing as an aging and silver industry, and the proportion of elderly people using them has been rapidly increasing. However, the rapid growth of the silver industry is not enough for the management system as well as the national financial resources.

For example, the elderly who are uncomfortable for a long period of time are left unattended for a long time, and the motor nerves are further slowed down or relatively healthy elderly people are lying in bed in the same position for a long time.

It is also reported that falls occur frequently when elderly people whose body movements are unnatural and fall apart from their beds. According to a survey on the type of nursing home accidents conducted in 2012, more than 80% of accidents are falls as shown in the figure.

These falls can be attributed to the lack of timely response by the managers responsible for the care of elderly and protected patients in nursing homes. In addition, there are frequent accidents of elderly people and patients in hospitals and nursing homes.

The Ministry of Health and Welfare, which manages the medical institution, establishes the operating rules of the medical institution and carries out the fall risk scale and pressure ulcer risk scale. It also checks whether the provision of service for change of position or wheelchair is progressed according to the risk .

In addition, by establishing the staffing standards for nursing hospitals and nursing homes, nursing hospitals have one nurse for every 6 patients, and nursing homes have one nurse for every 2.5 people. Nevertheless, news about falling and falling accidents and news that deep pressure has been worsened by pressure ulcers are being transmitted through media. In reality, caregivers in most nursing care facilities are nursing more elderly and protected persons than regulation.

It is very difficult to protect elderly patients in a timely manner or take timely responses in such situations. In the future, if the trend of aging accelerates, it is necessary to take a timely action to detect behavior or movements of elderly and guardian traders and to inform the caregivers and administrators of the need for a system to prevent incidences of bedsore and falls Do.

However, the conventional systems use a camera or an infrared sensor to incur an initial installation cost and a maintenance cost to continuously manage the installation cost. It is difficult to install such a system because most of the nursing homes have a lack of budget. In general households, there is a limit to paying for such expensive installation and maintenance costs. In addition, there is a need for expertise in installing necessary terminals in the system. For example, installing a camera, an infrared detector, a gas / temperature / water usage detector, etc., requires a technician's visit.

For example, patent 10-2013-0021614 falls from a similar context to the present invention, but in a method for resolving a bed fall in an elderly patient, a camera is used to monitor the skeleton image of the elderly patient And it is necessary to transmit a large amount of information in order to monitor it. Therefore, it is solved by using communication such as Wi-Fi or 3G / 4G. This method has the effect of detecting the fall by detecting the behavior of the elderly patient through the camera, but the expensive camera equipment is installed on the wall of the separated building and the expensive communication is used to technically fall Although it may be possible to solve the problem, it seems that commercialization of the product is unrealistic considering the infrastructure of the facility and the cost of use such as the backward budget of the nursing facility. In particular, this patented technology only considers the detection of falls in bed.

In addition, the existing behavior recognition technology using the ultrasonic sensor is inconvenient because the corresponding sensor must be attached on the chest, and it is impossible to recognize the behavior unless the user consciously attaches the sensor. Especially, it is not practical for elderly people to use sensors with complex or conscious use.

In addition, the existing behavior recognition technology using a camera or an infrared sensor induces psychological tension that the elderly is being monitored for their privacy. In other words, it treats the user as a target of surveillance, which causes restriction of daily life and psychological discomfort. In addition, in the conventional elderly person management systems, various sensors (camera, infrared sensor, ultrasonic sensor, etc.) are used for continuous monitoring, and a battery type power supply device or a household voltage device is used for power supply.

This approach is an important constraint on providing ongoing management services due to high power consumption or frequent battery replacement. As a result, the nursing home experiencing difficulties due to insufficient workforce will be a constraint on providing ongoing management services.

Therefore, there is a desperate need for a technique that can monitor the physical activity without psychological burden in the state where the elderly and the patient are unconscious.

Accordingly, a problem to be solved by the present invention is to provide a method and apparatus for monitoring the physical activity of an elderly person and a patient without any psychological burden, And to provide a smart mat system for preventing dangerous situations.

The smart mat system according to an embodiment of the present invention includes a smart mat for measuring a motion of a subject and generating a sensor signal to control a pump to change a position of a user; And a user terminal for monitoring and controlling the smart mat, wherein the smart mat comprises: a sensor unit positioned on the pump and sensing status information of a management subject using the smart mat; A position recognition module for recognizing a pressure part position state of the management subject using the state information of the management subject sensed by the sensor part; A risk situation detection module for detecting a risk situation based on a predetermined criterion according to a specific situation through a pressure site location state of the management subject recognized by the location recognition module; And a first control module for controlling the pump according to the detection of the dangerous situation detection module.

The smart mat also includes a pump including an expansion mechanism including two or more arranged in the column direction, wherein the first control module controls the pump so that the body part, So that the position of the management subject can be changed by expanding at least one of the expansion mechanisms.

In addition, the sensor unit includes a first block 311 in which sensors are positioned to sense pressure and position of the posterior capsule, scapula, ear, and shoulder through predetermined human body information; A second block 312 in which the sensors are positioned to sense the pressure and position of the fingers, elbows, iliac crest, sacrum, pubis, full bones, electrons, femur; And a third block 313 in which the sensors are positioned to sense the position and pressure of the side of the Achilles tendon, heel, knee, knee lateral, calf, medial and lateral lateral bones, foot, and foot.

According to the smart mat system for preventing the onset of diseases and the dangerous situation by recognizing the status of the person to be managed according to the present invention, the maintenance cost is low as well as the initial installation cost, and the elderly person and the patient are not conscious, It has the effect of monitoring the behavior.

In order to clearly describe the present invention, parts that are not related to the description are omitted, and the same reference numerals in the drawings denote the same members.

FIG. 1 is a diagram conceptually illustrating a smart mat system for preventing the onset of a disease and a dangerous situation through recognition of a state of a management subject according to an embodiment of the present invention.

1, 3A, and 4A, the SmartMat system 100 for preventing diseases and preventing a dangerous situation by recognizing the status of the management subject includes a smart mat 110, a user terminal 120, and the like The smart mat 110 includes a sensor unit 301, a position recognition module 302, a positional situation sensing module 303, a first control module 304, a database 305, and a first communication module 306 . The user terminal 120 also includes a management subject status monitor module 401, a risk status notification module 402, a second control module 403, a database 404, and a second communication module 405.

In addition, an external server may be installed in order to monitor the status of the management object from a plurality of smart mats 110 through one user terminal 120 and extend it to prevent a dangerous situation.

(emplacement)

The smart mat 110 shown in FIG. 1 is installed in a place where a management subject such as an elderly person and a patient who is inconvenient to move resides. The smart mat 110 may be installed at various positions where the smart mat 110 can lie down or sit on a bed, floor, or the like of a person to be administered such as an elderly person and a patient who are inconvenienced. In addition, the smart mat 110 includes sensors (not shown) that can detect when the management subject touches the mat surface.

(Sensor arrangement)

The sensor unit 301 of the smart mat 110 shown in FIGS. 1 and 3A is composed of a plurality of sensors. The sensors include various sensors capable of detecting status information of a target such as a pressure sensor, an infrared sensor, and an ultrasonic sensor Can be used.

The sensor arrangement 310 of the SmartMat shown in FIG. 3B locates the pressure ulcer area of the management subject having various elongations so as to focus on the key arrangement. The eardrum, shoulder, frontal spine, electronic, femur, inferior knee, knee side, lateral side of the pressure ulcer, Place the sensor so that it can focus on the side of the calf, the medial side (the radiating bone), the lateral side (the radiating bone), and the foot. Also, by using age-specific body size data surveyed by the National Institute of Standards and Technology of the Ministry of Industry and Commerce of the Republic of Korea, it is arranged so as to be able to sense the pressure ulcer area suitable for various elongation.

For example, a sensor may be deployed 310 as the sensor portion 301 of the SmartMat shown in FIG. 3B. A block 311 for mainly sensing the pressure and position of the scapula, shoulder blade, ear, and shoulder; a block (311) for mainly sensing the pressure and position of the fulcrum, the elbow, the iliac crest, the sacrum, the pubis, 312), a block 313 for mainly sensing the positions and pressures of the side of the foot, the heel, the inside of the knee, the side of the knee, the calf, the inside and the outside (the radiating bone) .

The smart mat 110 shown in FIG. 3A senses the position of the management subject and the pressure applied to each part of the body in real time to grasp the state of the management subject. And take appropriate measures to prevent risks to the management.

The position recognition module 302 shown in FIG. 3A calculates the height of the management subject by grasping the length of the foot from the head of the management subject. The position recognition module 302 determines whether or not a specific portion of the sensor unit 301 is located in any of the body parts of the body using the body size data for each age received from an external system (for example, the National Institute of Standards and Technology, Region. Then, the position of the pressure ulcer area corresponding to the calculated height is determined.

Also, the position of the management subject is grasped based on the sensor unit 301 to which pressure is applied. The body part is divided into a plurality of blocks so as to discriminate the shape of a specific body, and the recognition of the specific position sensor is performed for each block. The shape of the body part is identified and the position of the patient is grasped.

The dangerous situation detection module 303 shown in FIG. 3A periodically detects the state of the management subject by using the data obtained by the sensor unit located at the incident site and the position of the attack site corresponding to the position and height of the management subject.

The state of the management subject is represented by S_STAT shown in FIG. 2A, whereby the state of the management subject is determined by i) a general state (the state of the subject to be supervised is a state of repetition, positioning, pressure accumulation of a specific body part, State (a state where the pressure is sustained in a specific region of the management subject for a predetermined time or more, a risk of falling state, a state of falling occurrence, a state of unauthorized departure of the management subject, etc.).

i) In the case of the normal state, it transmits the status information of the supervisor periodically detected to the user terminal. The period is arbitrary. For example, according to the Korea Pressure Ulcer Nursing Handbook, in order to prevent pressure ulcers, you should change the attitude of your supervisor once every 2 hours. Accordingly, the user terminal 120 shown in FIG. 1 not only transmits the status information of the management subject when requesting, but also changes the status of the visualized management subject to the management subject monitor module of the user terminal at least once every 30 minutes, It informs the status of the management subject.

ii) When the dangerous situation detection module 304 shown in Fig. 3A detects a dangerous situation in the case of a dangerous state, for example, a risk of a bed sores occurrence, a risk of falling, etc., the control module 304 And transmits the operation result of the control module to the user terminal 120 shown in Fig. And transmits to the user terminal a measure to be taken by the user according to the state of the management subject.

If the pressure on the body part of the supervisor continues to accumulate for a certain period of time (for example, more than 2 hours in accordance with the Korea Pressure ulcer Nursing Handbook), it is determined that the pressure ulcer is dangerous. The first control module 304 shown in FIG. 3A controls the pump 320 shown in FIG. 3C so that the body part having a pressure longer than a predetermined time is no longer subjected to pressure, Expands one or more to change the position of the management subject.

After the pressurization is continued to prevent the pressure applied to the body-specific parts that have accumulated over a certain period of time from being sustained, information on the condition that has been taken (for example, (S_PRS 200 indicating a duration time, S_STAT (200) indicating a status of a person to be supervised, A_STAT (200) indicating an expansion state of an expansion mechanism, etc.) to the user terminal shown in FIG.

When the smart mat 110 shown in FIG. 1 is installed in a bed, that is, a furniture in which a person to be supervised is at risk of falling because of a vertical stand capable of stretching and lounging for rest or sleeping, a risk of falling is detected And sends a warning notification to the user terminal shown in FIG. For example, the position recognition module 302 shown in FIG. 3A divides the sensor unit 301 vertically into left and center right groups on the bed of the management subject. If the sensor of one group of the two groups except for the sensors of the central group senses the bias of the body of the management subject and the sensor of the center of the opposite group does not detect the body of the management subject, Lt; / RTI > The dangerous situation detection module 303 judges this as a fall risk state and informs the user module of the user that the management subject is in danger of falling.

If the management subject leaves the SmartMat 110 shown in FIG. 1 for a certain period of time without the user's permission, it is determined as a situation requiring assistance or a state of disengagement of the management subject and transmitted to the user terminal.

In the database 305, the pressure duration of each pressure sensing part of the management subject, the state of the management subject, and the air pump control state are stored. This is to analyze the collected data and to derive a meaningful value and monitor it at the user terminal. For example, at the user terminal, not only the current state of the patient can be confirmed, but also the daily, weekly, and monthly information indicating whether the pressure has persisted for each part of the body can be confirmed.

When the management object contacts the smart mat 110 shown in FIG. 1, the smart mat 110 generates status information of the management object and transmits the status information to the user terminal 120. Various wireless communication schemes may be used to transmit information to the user terminal 120. [ For example, when the smart mat 110 and the user terminal are connected wirelessly, various wireless communication protocols such as Bluetooth, infrared communication, WiFi, zigbee, RF communication, ultra wideband (UWB) Therefore, the status information of the management subject can be transmitted to the user terminal.

FIGS. 2A and 2B are data values measured from a smart mat and transmitted to a terminal, which are tables for illustrating a management subject pressure duration, a management subject pressure sensing region, a management subject state, and a pump control state. 2A, S_ID is unique information capable of identifying a management subject, S_PRS indicates a pressure duration of each part of the management subject, S_STAT indicates that the state of the management subject is a general state (rotation, positioning, etc.) State, fall occurrence state, unauthorized departure state of the management subject, etc.). The data received in FIG. 2A can be confirmed through the terminal, and in FIG. 2B, A_STAT indicates a pump operation control in which the user confirms and operates the pump operated.

The user terminal 120 shown in FIG. 4A can receive data transmitted from the smart mat 110 through the management subject monitor module 401 to determine the state of the management subject (general state of the repetition and positioning, risk of falling, Departure, etc.) to the user.

4B, the rotation status terminal display 411 grasps the current status of the management subject according to the data S_STAT transmitted from the smart mat 110, and displays the current state of the management subject based on the S_PRES, The pressure accumulation is shown by color.

According to the pressure ulcer management guidelines that patients with pressure ulcers should be changed at least once every 2 hours, when pressure is continuously detected for 1 hour or more, red is displayed. When pressure is detected for 1 hour or more, yellow is displayed. do.

The right side positioning state terminal display 412 indicates the pressure accumulation degree of each bed portion when the management subject receives the S_STAT 200 from the smart mat 110 in the right side positioning state and the left side positioning state terminal display 413 displays, Shows the pressure accumulation of each part when S_STAT is in the left-side positioning state.

4C is a graph showing the pressure accumulation degree of each portion of the bedsurge unlike the terminal display 411 in which the state of the management subject is expressed in color. The pressure accumulation degree display 421 of the subject of the current pressure sorne by the current pressure sorter shows a graph with the abscissa as the abscissa and the pressure accumulation time as the ordinate.

The pressure accumulation degree display section 422 for each weekly pressure ulcer occurrence position represents the cumulative data of the management subject stored in the database 404 by month and the pressure accumulation degree display section 423 for each weekly pressure ulcer occurrence position shows the accumulated cumulative data Data is shown weekly.

FIG. 4D shows an alarm 431 to the user terminal using the dangerous situation notification module 402 when the data S_STAT 200 of the management subject is in a dangerous state. The time when the dangerous situation has been reached through the alarm 431 is shown as a sequential list 432.

And changes the position of the management subject based on the data S_PRES measured through the smart mat 110. 4E, when the pump 320 appears black on the terminal monitor 441 when the pump 320 is not operated and when the pressure is sensed according to the S_PRES 200, on the basis of the accumulated pressure duration S_PRES 200, (442) to the right or to change the position to the left (443).
