Description

Patient management device based on 2D temperature measurement {PATIENT ADMINISTRATION DEVICE BASED ON 2 DIMENSION TEMPERATURE CONTROL}

The present invention relates to a patient management device based on two-dimensional temperature measurement.

In hospitals and nursing homes, problems caused by falls of patients frequently occur. Conventionally, a fall prevention method through a physical sensing device has been mainly used as a countermeasure for a patient's fall accident.

The fall prevention method using a physical detection device is a method of detecting a fall by attaching a sensor to the patient, the patient's clothing or bedding equipment, which makes the patient's activities uncomfortable or increases the stress on the patient due to the noise generated from the installed pressure pad. It is not helping the patient's hospital life as expected. In addition, in hospitals, a physical sensing device may cause inconvenience because arrangement or replacement of bedding products frequently occurs due to hygiene problems.

In addition, as the number of people living alone has recently increased, social safety issues have arisen due to the death of people living alone. However, there is currently a lack of countermeasures for coping with emergency health situations by continuously monitoring the status of a person living alone, leaving a place, or decreasing body temperature.

Hereinafter, the present invention will be described in more detail based on a preferred embodiment of the present invention. However, the following examples are merely examples to aid understanding of the present invention, and thus the scope of the present invention is not reduced or limited.

The present invention proposes an apparatus and method that can use a two-dimensional temperature measurement function for patient management and management of a person living alone. To this end, in the present invention, in order to continuously monitor changes in body temperature and find problems (fever, decrease in body temperature) in this result, changes in body temperature are classified into a time domain (time-based monitoring), and the result of this recording Algorithm that can suspect fever based on is needed. In addition, an algorithm with the same structure is required for lowering body temperature.

More precisely, if a two-dimensional temperature measuring device is placed per patient, the patient is It is possible to see in advance the degree of movement of the body to the edge of the bed and the level of danger. At this time, in the present invention, when a patient 1 temperature sensor is installed, it is possible to induce a fall by ventilating the patient by alerting the patient by sounding an alarm and detecting it before the fall.In this case, the fall alarm and situation are not required to rely on the fall determination algorithm. Propagation is possible.

That is, in the present invention, since it is possible to immediately determine immediately before and after a fall, the quality level of patient management can be greatly improved. In the case of severely ill patients, it is possible to detect and notify a fall leading to death in advance, so it is possible to block a very dangerous medical situation early.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a diagram illustrating a configuration of a patient management apparatus based on 2D temperature measurement according to an embodiment of the present invention.

Referring to FIG. 1, the patient management apparatus 100 based on two-dimensional temperature measurement according to an embodiment of the present invention is a temperature measuring unit that generates temperature measurement information by sensing the temperature of a monitoring area in a non-contact two-dimensional temperature measurement method. (200), and a monitoring unit 300 for monitoring at least one of a change in vital information of a monitored person and departure from a monitoring area of a monitored person by using the temperature measurement information.

The temperature measuring unit 200 may generate temperature measurement information in a mosaic form obtained in two dimensions from a monitoring area set in various ways according to an installation location. In this case, the temperature measuring unit 200 may simultaneously detect the temperature of each pixel by dividing the person to be monitored in the monitoring area and its surroundings into a plurality of pixels. To this end, the temperature measurement unit 200 divides the surveillance area into a plurality of pixels, and may include a plurality of 2D temperature measurement sensors 210 arranged to match each of the plurality of pixels.

Here, each of the plurality of 2D temperature measuring sensors 210 may detect a temperature within a corresponding pixel using an infrared detection method. In addition, the temperature measuring unit 200 may collect temperature information sensed by each of the plurality of two-dimensional temperature measuring sensors 210 to generate temperature measurement information in a mosaic form obtained in two dimensions.

On the other hand, the temperature measuring unit 200 sets the resolution of the plurality of two-dimensional temperature measuring sensors 210 to be low, or using a low-resolution two-dimensional temperature measuring sensor 210, or a plurality of two-dimensional temperature measuring sensors 210 It is possible to reduce the resolution of the temperature measurement information in the form of a mosaic by reducing the number of Through this, the temperature measuring unit 200 may measure only the body temperature of the subject to be monitored to relieve the unpleasant feeling of the subject to be monitored according to the portrait right or behavior monitoring, or to prevent the occurrence of additional problems.

The monitoring unit 300 receives two-dimensional temperature measurement information from the temperature measurement unit 200, uses the received temperature measurement information to monitor changes in vital information of the monitoring target or departure from the monitoring area of the monitoring target, and externally monitor the monitoring results. Can be transferred to.

To this end, the monitoring unit 300 includes a noise filter 310 that removes noise components introduced into electrical signals output from the temperature measurement unit 200, an algorithm for determining a monitoring target from two-dimensional temperature measurement information, The control unit 320 that performs at least one of an algorithm for determining fever, an algorithm for determining a decrease in body temperature, an algorithm for determining a motion slowdown, an algorithm for determining a fall or bed departure, and the determination criterion information related to an algorithm performed by the controller 320 It may include a memory 330 that stores a memory 330, an alarm device 340 that issues at least one of a visible and audible alarm according to control by the controller 320, and a communication unit 350 that transmits a monitoring result to the outside.

Here, the communication unit 350 uses at least one of short-range wireless communication, wired communication, and public network communication to transmit the monitoring result through the network 400 to the control center 510, the medical staff call system 520, and other interlocking systems 530. It can be transmitted with at least one of.

Specifically, the controller 320 may perform correction to recognize the temperature measured in two dimensions as body temperature. That is, the controller 320 may perform a process of converting the temperature information into reliable body temperature in consideration of the distortion (or error) of the heat wavelength according to the measurement distance. According to an experiment, in the present invention, a deviation of about 2 degrees was shown, and by adding this to a correction factor, very reliable results can be obtained.

In addition, the controller 320 may monitor the presence or absence of a subject to be monitored and a change in abnormal body temperature of the subject according to the vital information set based on the temperature measurement information, and may determine whether an alarm is issued or the like.

In addition, the controller 320 may detect the movement of the person to be monitored through the distribution of body temperature as shown in FIGS. 2 and 3. The motion detection of the monitored person by the controller 320 is not an image capturing technique such as a camera, and thus can be performed regardless of the problem of the portrait right of the monitored person.

Here, referring to FIG. 2, the patient management apparatus based on two-dimensional temperature measurement according to an embodiment of the present invention is exemplarily installed on the ceiling of a hospital room to detect movement of a plurality of monitored persons lying on the bed 50 can do. In addition, referring to FIG. 3, the patient management device based on two-dimensional temperature measurement according to an embodiment of the present invention is exemplarily installed on the head of the bed 50 and the movement of the monitored subject lying on the bed 50 Can be detected.

In addition, the control unit 320 continuously monitors the change in vital information of the monitored person, and divides the change in body temperature into a time domain (time-based monitoring) in order to find problems in this result, such as fever and body temperature decrease. Can be recorded. To this end, the controller 320 may include a timer for measuring time.

Also, the controller 320 may perform an algorithm capable of suspicious of fever or decrease in body temperature based on a result of recording changes in vital information. Here, the difference between fever and decrease in body temperature is the speed of change in vital information.

This should be set based on body temperature-based vital information, and the control unit 320 manages the delta value (a value that regulates the allowable rate of change of body temperature rise or fall over time), thereby alarming and situation through changes in body temperature. You can decide whether to spread.

In addition, the controller 320 may determine the deviation of the monitoring target person from the temperature measurement information. Here, the control unit 320 may classify the departure of the monitored person from the surveillance area as a fall or a bed departure. In this case, the control unit 320 may classify a fall or a bed departure based on whether to return within a specified time.

Hereinafter, an algorithm for issuing an alarm and propagating a situation by determining the occurrence of an abnormal temperature by the controller will be described with reference to FIG. 4.

Referring to FIG. 4, the control unit 320 may perform an algorithm of synthesizing two-dimensional temperature measurement information to determine whether an abnormal temperature has occurred and to transmit data for alarm generation and situation propagation accordingly.

Specifically, the controller 320 may perform 2D temperature sampling by using 2D temperature measurement information with reference to FIG. 5 (S110 ). In addition, the control unit 320 may divide the monitoring region into one or more sub-regions, such as a four-person room, from the two-dimensional temperature measurement information (S120).

Also, the control unit 320 may calculate a temperature distribution of the sub-region. For example, the controller 320 may calculate a temperature distribution of the sub-regions divided into regions 1,2, 3, and 4 (S130).

In addition, the control unit 320 may determine the body temperature information calculated for each sub-area using a pre-set vital information change determination method (S140). For example, when a small number of pixels of 40 degrees or higher are detected, the controller 320 may be a hot beverage, and thus may be ignored in determining the change in body temperature of the person to be monitored.

The controller 320 detects an abnormal temperature from the temperature distribution of the sub-region (S150), and when it detects the abnormal temperature, issues a self-alarm (S155), or delays a certain time when the abnormal temperature is not found (S160). The maximum temperature for each sub-region may be transmitted (S170).

In addition, the controller 320 may determine whether the person to be monitored exists in consideration of the distribution of the body temperature of the person to be monitored and the number of combinations of normal body temperature pixels in the sub-region in order to clearly determine the person person to be monitored based on the vital information.

Specifically, the controller 320 may determine whether the number of pixels having a temperature equal to or higher than a reference value is approximately 10% or higher of the total area of the sub-region with reference to FIG. 6 (S210 ). If it is less than 10%, the controller 320 cannot determine whether the person to be monitored exists, and thus may terminate the determination algorithm.

Also, the control unit 320 may determine whether the distribution of pixels having a temperature equal to or higher than the reference value is biased (S220). In this case, if the distribution of pixels is biased, the control unit 320 may determine the existence of the person to be monitored (S230). If the distribution of pixels is not biased, the controller 320 cannot determine whether the person to be monitored exists, and thus the determination algorithm may be terminated.

Hereinafter, with reference to FIG. 7, after the control unit determines whether the person to be monitored exists or not, an algorithm for determining the fall or departure of the person to be monitored will be described.

Specifically, referring to FIG. 7, the control unit 320 determines the fall or bed departure of the monitored person based on whether the monitored person returns to the set time after the fall or the bed departure of the monitoring target according to the algorithm for determining I can judge.

First, the controller 320 may determine whether a person to be monitored exists in the monitoring area (S310). In this case, if the person to be monitored does not exist in the monitoring area, the controller 320 may determine whether a fall determination time has been set (S320). If the subject to be monitored exists in the monitoring area, the controller 320 may cancel the timer operation (S315).

In addition, the control unit 320 determines whether the fall determination time has been set, and if the fall determination time is not set, the control unit 320 may set the fall determination time in a timer (S330). If the fall determination time is set, the controller 320 may decrease the timer value (S340).

After decreasing the timer value, the control unit 320 may determine whether the timer value becomes zero (0) (S350). If the timer value becomes zero, the controller 320 cancels the operation of the timer (S360), determines that the person to be monitored has fallen, and transmits data on the issuance of an alarm and propagation of the situation to the outside (medical staff) ( S370). If the timer value has not reached zero, the controller 320 may continue to decrease the timer value.

On the other hand, the patient management device based on 2D temperature measurement according to an embodiment of the present invention leaves the role of a simple sensor for 2D temperature measurement and automatically issues an alarm when communication with an external receiver is lost, so that nearby people (patients, nurses, In order to be able to receive help from caregivers, etc.), it is possible to set alarm criteria, including criteria for determining the person to be monitored. Through this, the patient management apparatus based on two-dimensional temperature measurement according to an embodiment of the present invention may set a reference value to actively determine itself and issue an alarm.

Specifically, the target for setting the alarm criteria may include at least one of vital reference information, installation reference information, use reference information, configuration reference information, local communication information, and public network communication information.

Here, the target for setting the vital reference information may include at least one of a body temperature determination reference temperature, a fever determination reference temperature, a body temperature decrease reference temperature, and a fall or bed departure determination time. In addition, the target for setting the installation reference information may include at least one of whether a bed head is attached, whether a ceiling is requested in the hospitalization room, and bed area information when the ceiling of the hospitalization room is attached. In addition, the target for setting the use criterion information may include at least one of whether to manage a patient or to manage a person living alone. Also, the target for setting the configuration reference information may include at least one of a local (internal) network connection, a wireless or wired connection, and a public network connection.

In addition, the setting target of public network communication information may include at least one of an IP address of a temperature sensor, Internet access information, router information, server access information, and SIM card information.

When the patient management device 100 based on two-dimensional temperature measurement according to an embodiment of the present invention is operated for the purpose of managing a person living alone outside of a hospital, it must be installed on the ceiling of the corner of the room and operated independently as shown in FIG. Therefore, it is possible to perform the function of alerting the person living alone and propagating the situation through the public network by issuing an alarm after determining itself based on the above-described criteria.

Here, a communication configuration when independently operated for management of a person living alone will be described with reference to FIG. 9.

In addition, in the case of using a mobile communication network such as LTE, SIM information is provided to the patient management device based on 2D temperature measurement according to an embodiment of the present invention in a software or hardware method, and through this, the LTE network is accessed to communicate with the control center. I can. In addition, when using the Internet, it is possible to propagate the situation to the control center by embedding a LAN or WiFi function.

For reference, in the case of managing a person living alone, it is very important to recognize the complex process of lowering body temperature and slowing movement patterns.When only the body temperature decreases, when there is no movement or when there is a decrease, and according to the complex result, alarm and situation propagation is decided. This also depends on vital information. However, in the case of the elderly living alone, since vital information may act differently according to aging, proportional arithmetic according to age is required.

Hereinafter, an algorithm for monitoring a death or emergency situation of a monitored person in a patient management apparatus based on two-dimensional temperature measurement according to an embodiment of the present invention will be described with reference to FIG. 10.

The control unit obtains a two-dimensional temperature sampling through the temperature measurement unit, determines whether the decrease in body temperature continues after designating the subject to be monitored according to the algorithm for specifying the subject to be monitored, and determines whether the decrease in body temperature continues, and determines the slowing of the movement pattern. This is a two-dimensional temperature measurement-based patient management device that issues a self-alarm and propagates the situation to the outside when the motion pattern is slowed.
