Description

Medical patch equipped with variable QR code and emergency notification system using the same {medical patch equipped with variable QR code and emergency notification system using the same}

The present invention relates to a medical patch having a variable QR code and an emergency notification system using the same, and more particularly, to a medical patch that converts a signal received from a sensor unit that measures a patient's bio-signal into a QR code and displays it on the front surface of the medical patch so that a third party can identify the patient's condition or transmit the patient's condition to a medical institution to enable emergency treatment, and an emergency notification system using the same.

A medical patch usually refers to a patch that is attached to the body of a patient or user to exhibit a medicinal effect or to measure a state of the body.

There are several types of medical patches, but they can be simply divided into a medicine patch that penetrates the body of a patient or a user and a bio-signal measurement patch that measures a certain value of a patient's body condition.

The bio-signal measurement patch is attached to the patient's body in the form of a patch and can transmit the patient's condition to a specific device.

On the other hand, at the emergency site, the patient's condition becomes very important. In order to know the patient's condition, there is no other way than to check whether the person at attention is taking a pulse or breathing, and it is practically difficult to have a measuring device that can measure the patient's condition even where there is a first aid kit.

In particular, in the case of islands and mountainous areas, the environment is even worse, so it is difficult to know what condition a patient is in when a patient occurs, and even when calling an ambulance, there is a problem in that you have to rely on 119 calls to know what to do until the ambulance arrives.

In order to solve this problem, the conventional technology discloses the patient's forearm to measure the biosignal and transmit the patient's biometric information to the medical staff remotely through a ubiquitous remote network.

1 is a diagram showing the overall configuration of a medical patch having a variable QR code according to an embodiment of the present invention.

Referring to FIG. 1 , a medical patch having a variable QR code according to an embodiment of the present invention includes a sensor unit 100 that measures a patient's bio-signal, a control unit 200 that converts the bio-signal received from the sensor unit 100 into a QR code, a QR code display unit 300 that displays the QR code converted by the control unit 200, and the sensor unit 100, the control unit 200, and the QR code display unit 300. ) is mounted, and includes a patch unit 400 attached to the body of the patient.

The sensor unit 100 measures various vital signs of the patient. It may include all bio-signals required in the medical field, and for example, the patient's electrocardiogram, respiratory rate, body temperature, blood pressure, oxygen saturation, blood sugar, and the like. In addition, a blood collection unit (not shown) may be further included to additionally analyze blood, and the sensor unit 100 may analyze the blood collected from the blood collection unit. It may include blood sugar, etc., and may include all kinds of tests that can be tested with blood.

On the other hand, when the body temperature is additionally measured, a high fever warning may be given, and a specific infection such as corona or influenza may be warned. In particular, when a warning is issued due to high fever, a body fluid collection unit (not shown) capable of collecting body fluid may be additionally provided to perform a corona or influenza test. When corona or influenza is determined by performing a corona or influenza test on the body fluid collected from the body fluid collection unit, the quarantine measure may be changed to a QR code to be described later and displayed. If high fever is checked, the corona or influenza test may take several minutes to several tens of minutes.

The control unit 200 converts the biosignal received from the sensor unit 100 into a QR code according to a standard. In this case, the QR code may be converted into a color QR code or a general black and white QR code. The QR code may include the patient's bio-signal information as well as time and place. That is, a location can be displayed from a GPS sensor, which will be described later, and time can be included through a built-in clock.

As will be described later, the control unit 200 can update the QR code at regular intervals to display the patient's bio-signals in the latest fashion. In addition, the controller 200 has a built-in memory (not shown), and can store bio signal histories according to time and place in the memory. In addition, the patient's bio-signal according to the patient's moving speed may be recorded. The bio-signal of the patient may affect the movement speed, and if an emergency occurs according to the movement speed, an emergency alarm may be displayed on the QR code display unit to be described later.

The QR code display unit 300 displays the QR code converted by the control unit 200 on the screen. A general display may be used, but it is preferable to use a flexible display.

The QR code displayed on the screen is a color or black and white QR code, and is periodically updated and displayed as described above.

In addition, as described above, quarantine warnings, emergency notifications, and the like can be displayed separately, or can be displayed by being embedded in the QR code. An LED lamp line may be connected along the outer edge of the QR code display unit 300, and a patient's condition may be indicated according to a color emitted by the LED lamp line. That is, for example, green indicates a stable state, yellow indicates a specific disease condition, red indicates an emergency situation, and orange indicates a quarantine warning. In this case, the intensity can be indicated according to the degree of flickering when indicated according to the color. That is, even in the case of red, the flickering speed may increase as the vital signal becomes urgent.

Meanwhile, the color may be different depending on a specific disease. That is, for example, in the case of heart disease, when the heart rate or electrocardiogram is low, a defibrillator to be described later needs to be used. Therefore, the white color may blink to indicate that the defibrillator can be used.

The patch unit 400 includes the sensor unit 100, the control unit 200, and the QR code display unit 300, and is formed in a patch shape so as to be worn on a patient's body. That is, the outer portion includes an adhesive portion (not shown) so that the entire medical patch can be closely adhered to the patient's body. The sensor unit 100 is attached to the bottom of the inner surface to be in close contact with the patient's body, thereby measuring the patient's biosignal.

The shape of the upper tooth patch unit 400 may be of various shapes, but it is preferably formed in a shape that can basically cover the patient's chest.

2 is a diagram of the configuration of a sensor unit of a medical patch having a variable QR code according to an embodiment of the present invention.

Referring to FIG. 2 , the sensor unit 200 may include an electrocardiogram sensor 110 for measuring the electrocardiogram of the patient, a respiratory rate sensor 120 for measuring the respiratory rate of the patient, a body temperature sensor 130 for measuring the patient's body temperature, and a blood pressure measurement sensor 140 for measuring the patient's blood pressure. Here, the patch unit 400 is sized to cover the patient's chest, the electrocardiogram sensor 110 has electrocardiogram sensing elements provided at at least three locations of the patch unit 400, the respiration rate 120 sensor is provided in the center of the patch unit 400, and the blood pressure measurement sensor 140 is connected to one side of the patch unit 400 and provided separately.

The electrocardiogram sensor 110 measures the electrocardiogram of the patient's vital signals, and sensing elements should be attached to the body of the patient at least three places, but should be placed at a position surrounding the heart. That is, it is arranged to surround the heart and measures the electrocardiogram of the patient.

Respiratory rate sensor 120 is a sensor for counting the patient's respiration rate, and is preferably disposed in the central portion of the patch unit 400, but is irrelevant as long as the respiration rate can be measured.

The body temperature sensor 130 is a sensor capable of measuring a general body temperature, and can be placed anywhere on the patch unit 400 as long as it can be in contact with the patient's body.

The blood pressure measuring sensor 140 is a sensor capable of measuring general blood pressure, and is connected to the patch part 400 by a line, and is formed in a shape surrounding a patient's arm. Or, as another embodiment, it may be inserted into the finger in the form of a ring.

Referring back to FIG. 2 , the sensor unit 100 may further include an oxygen saturation measurement sensor 150 that measures oxygen saturation of the patient. In addition, the medical patch may further include a defibrillator 160 connected to one side of the patch unit 400 .

The sensor unit 100 may include an oxygen saturation measurement sensor 150 capable of measuring the patient's oxygen saturation, and is generally measured at a place where blood vessels such as a patient's finger are relatively visible.

In addition, a defibrillator 160 may be further included on one side of the patch unit 400 to be used when a patient is in an emergency, and the defibrillator 160 may include a separate battery. As described above, when the defibrillator 160 determines that there is a problem with the heart based on the patient's heart rate, electrocardiogram, respiration rate, etc., an emergency alarm is issued with the QR code or a separate display (external LED line, etc.) on the QR code display unit 300. In this case, a third person or paramedics nearby can operate the defibrillator 160.

FIG. 3 is a diagram of configurations of a control unit, a communication unit, and a GPS sensor of a medical patch having a variable QR code according to an embodiment of the present invention.

Referring to FIG. 3 , the medical patch may further include a communication unit 500 that transmits the QR code converted by the controller 200 to the user terminal 2000 or the manager server 3000 . In addition, the control unit 200 may update the bio-signal at regular intervals and convert it into a QR code. When converting the bio-signal into a QR code, the sensor value measured by the sensor unit 100 may be converted by including a priority value, and may be converted by including a patient condition or a candidate disease name.

The communication unit 500 may be equipped as an option, and may transmit the converted QR code to the user terminal 2000 or the manager server 3000. That is, only the QR code is transmitted to minimize the amount of communication, and the QR code may include time, place, etc. in addition to the biosignal of the patient, and information such as high fever warning and emergency alarm. In addition, the movement speed of the patient is included, and each patient's history (time, place, biosignal, etc.) may be included.

These contents can be converted into QR code and the converted QR code can be transmitted to the user terminal 2000 or manager server 3000 through the communication unit 500, or all information before being converted into QR code can be transmitted as it is.

The user single device 2000 or the administrator server 3000 that has received the QR code automatically displays related information such as the patient's biosignal through a decoding program, and paramedics or medical staff can check it.

The control unit 200 may periodically update all bio-signals obtained from the sensor unit 100 to convert the QR code. That is, the QR code is changed at regular intervals such as every second or every 10 seconds, and updated information is included therein.

When converting to a QR code, it may be converted by prioritizing the biosignals acquired by the sensor unit 100. That is, when decoding, the conversion is performed by giving priority so that the order of importance can be known first. For example, electrocardiogram, respiration rate, blood pressure, body temperature, and oxygen saturation may be displayed on the screen in order. Also, this order may vary depending on the condition of the patient. In other words, it can be expressed from the physical quantity in which the patient exhibits an abnormal symptom. If only the body temperature is high, the body temperature may be a priority.

Additionally, if an input field is provided in the QR code display unit 300 at all times so that information about the patient, such as the patient's age or gender, can be entered, it can be displayed in a priority order appropriate thereto. For example, if the patient is older, the respiratory rate may be indicated first.

The control unit 200 can determine the patient's condition from the biosignal acquired by the sensor unit 100 and convert it into a QR code, including possible disease names. For example, if the patient's body temperature is high, there is no abnormality elsewhere, and the respiratory rate is not constant, the QR code can be converted including possible candidate disease names such as corona or influenza, and the patient's condition. The QR code can be converted including classification into emergency, good, and safety.

In the case of candidate disease names, in order to simplify the configuration of the control unit 200, bio-signals may be divided into stages and represented by representative candidate disease names such as heart disease, hypertension, hypotension, and dyspnoea. That is, if the electrocardiogram is divided into stages and the electrocardiogram is less than a certain level, it can be expressed as a heart disease.

If the patient's condition is classified as critical and the QR code is converted, it is immediately possible to know which part of the bio-signal is the problem in the above priority order, which can be of great help in urgently treating the patient.

Referring back to FIG. 3 , the medical patch further includes a GPS sensor 600 that can determine the location of the patient, and the control unit 200 can convert the patient's location and the nearest hospital or pharmacy when converting the biosignal into a QR code.

By including the GPS sensor 600 in the medical patch, the position of the medical patch can be grasped, and when converting to a QR code, location information can be included and converted. In addition, if the location is secured, the location of a nearby hospital or pharmacy may also be included. For example, if a third party attaches a medical patch to a patient and scans the QR code with a smart device such as a mobile phone (user terminal), a nearby hospital or pharmacy can be displayed along with the patient's biometric information, patient condition, candidate disease name, etc. Such contents may be identically displayed in the manager server 3000 that has been transmitted.

The emergency notification system includes a medical patch 1000 having a variable QR code, a user terminal 2000, a manager server 3000, an ambulance terminal 4000, and a hospital terminal 5000 (hereinafter referred to as 'administrator server 3000, etc.'). send, etc. When transmitted to the manager server 3000, etc., the patient's vital signs, location, time, candidate disease name, high fever warning, emergency alarm, moving speed, nearby hospital, pharmacy, etc. can be known from the manager server 3000, etc., and instructions or other advisory matters can be sent to the user terminal 2000, or a call can be made through automatic comments.

As an embodiment, contents converted into QR codes in the medical patch 1000 may include patient bio-signals, location information, time, and the like. When such QR codes are transmitted to the manager server 3000 through the user terminal 2000, the manager server 3000 can deliver candidate disease names, nearby hospitals, pharmacies, and instructions or advisory matters to the user terminal 2000.

The user terminal 2000 includes an imaging device 2100 capable of photographing QR codes, a QR code recognition unit 2200 that recognizes QR codes, and a user terminal communication unit 2300 that transmits QR code information.

The imaging device 2100 may be a general camera, and the QR code recognition unit 2200 may recognize and interpret the QR code. In addition, the user terminal communication unit 2300 may transmit the QR code itself or transmit interpreted information.
