Description

[0001] APPARATUS AND METHOD FOR ASSISTING CHEST COMPRESSIONS [0002]

The present invention relates to a device and a method for assisting compression of chest, and relates to a device and a method for assisting CPR in a subject in need of CPR.

Cardiopulmonary resuscitation (CPR) is a first-aid measure to restore normal breathing and circulation during accidents such as heart attacks and drowning. It is used to purify the lungs connected to the lungs and to perform cardiac massage that externally pressurizes the chest And should only be administered to unconscious persons who are not breathing, and must be trained in CPR training.

In cardiopulmonary resuscitation, chest compressions assist the circulation of the patient's blood. In the cardiac arrest state, the blood flow to the important organs including the heart is stopped, so that the patient's chest can be pressed to maintain a certain degree of blood circulation.

In reference to the standardized CPR Guidelines 2010, it is recommended that chest compressions be performed in a range of at least 2 inches with a minimum of 100 compressions per minute, but chest compressions and depths are often lowered in practice. In addition, it is recommended to assist the ventilator with 8 to 10 ventilation per minute for patients who have undergone tracheal intubation, but hyperventilation is often induced. Hyperventilation increases the pressure in the thoracic cavity to lower the coronary perfusion pressure, The probability of recovery is lowered.

CPR refers to chest compressions that compress the chest during operation of CPR unless otherwise noted. The use of CPR and chest compressions does not mean a difference, Can be used in combination.

The main unit 101 can generate information related to chest compression, and the main unit 101 will be described in detail with reference to FIG. 2, which will be described later.

The connecting portion 102 extends from the main unit 101 and is connected at both ends so that the chest compression assisting device 10 can be worn on a part of the user's body. For example, in accordance with various embodiments of the present invention, the connection portion 102 may be adapted to secure the chest compression assisting device 10 to the wrist region of the user. More specifically, the connection portion 102 may be made of a urethane material, but is not limited thereto.

Specifically, fastening of the connection portion 102 can be accomplished by using a Velcro, a snap button, a magnet or a cable tie Method or the like. This has the effect of making the chest compression assisting device 10 simple to carry.

According to another example of the present invention, the chest compression assisting device 10 may include a detachable portion (not shown). The detachable portion is formed between the main unit 101 and the connecting portion 102 and can be fixed so that the main unit 101 can be detached or attached to the chest compression assisting device 10. [ In other words, the desorbing part can separate or fix the chest compression assisting device 10 and the main unit 101. [ The detachable part separates the chest compression assisting device 10 and the main unit 101 to allow the main unit 101 to operate and the main unit 101 of the other chest compression assisting device 10 to operate the chest compression assist device 10, respectively.

Such a detachable portion can provide convenience in use, such as moving, filling, or storing, with respect to the main unit 10, and can provide scalability such as using the main unit 101 of another chest compression assist device 10 It is possible.

For example, the charging unit may be configured to charge the power supply unit, and may be configured as a micro 5-pin. However, the configuration of the charging unit is not limited to those described above. For example, various configurations such as a wireless charging scheme may be applied. Meanwhile, the charging unit may be used as an interface capable of transmitting the information generated in the main unit 101 to the external device 20 via the wire.

FIG. 2 illustrates the operation of such a device for assisting compression of chest compressions according to an embodiment of the present invention. Referring to FIG. 3, referring to step S301, the chest compression assisting device 10 may be capable of estimating the angle of the performer's arm in performing chest compressions to more accurately perform chest compressions, Referring to S302, the chest compression assisting device 10 may measure the compression depth at which the performer presses the chest. Through steps S301 to S302, the chest compression assisting device 10 can determine whether the performer is pressing the chest with an appropriate angle, thereby improving the accuracy of chest compressions including CPR. In step S303, the chest compression assisting device 10 may output sound to guide CPR so that CPR can be performed more accurately.

2 is a configuration diagram of a main unit according to an embodiment of the present invention. 2, the main unit 101 includes a sensor unit 1011, an information generation unit 1012, a light source operation unit 1013, a communication unit 1014, a switch 1015, and an audio output unit 1016 do. However, the configuration of the main unit 101 is not limited to those described above.

The sensor unit 1011 can measure the compression depth of the chest compressions and measure the compression direction of the chest compressions. The sensor unit 1011 can measure at least one of the pressing depth and the pressing direction through the acceleration sensor and can detect at least one of the pressing depth and the pressing angle based on the offset and the signal change period according to the acceleration change of the main unit. More than one can be measured. For example, the sensor unit 1011 is a six-axis acceleration sensor, and the distance moved from the chest to the reference axis can be measured by the pressing depth.

More specifically, the sensor unit 1011 can detect a change in the position of the main unit 101, and the sensor unit 1011 can be an acceleration sensor. An acceleration sensor is a sensor that measures the dynamic force of an object such as acceleration vibration, impact, etc., and is a sensor that makes it possible to detect the motion state of an object. In other words, when performing chest compressions, the sensor unit 1011 can measure a case in which the chest is moved 4 to 6 cm in the cardiac direction from the chest of the subject to be chest compressed.

The information generating unit 1012 can generate information based on the measurement result of the sensor unit 1011. [ The information may be accuracy information indicating whether the chest compressions are performed correctly. For example, the information generating unit 1012 can generate information indicating that the chest is pressed correctly when it is measured through the sensor unit 1011 that the chest is moved 4 cm to 6 cm in the cardiac direction from the chest of the subject.

The sensor unit 1011 continuously senses the motion of the user, and when the acceleration pattern of the CPR is measured over a predetermined number, the information generating unit 1012 determines that the CPR operation is performed, At least one of the internal or internal parts of the apparatus 10 may be operated. This is because, in the case of using the chest compression assisting device 10, when a situation occurs in which CPR or chest compressions are performed and there is no burden or time to operate the chest compression assisting device 10, The power source can be automatically operated to provide a guide for chest compressions even if the pressing assist device 10 is not operated, and the convenience of the user can be increased.

Hereinafter, operations of the sensor unit 1011 and the information generating unit 1012 will be described in detail with reference to FIGS. 4A to 4B. 4A and 4B are views showing the operation of the sensor unit according to an embodiment of the present invention.

4A and 4B, the sensor unit 1011 may be designed as a six-axis accelerometer drive circuit for measuring the motion of the user's wrist performing CP compression including CPR, and may be used for CPR or chest compressions It is possible to measure the parameters calculated during the implementation.

Referring to step S401, the sensor unit 1011 may estimate the angle of the arm in CPR or chest compressions. (A) when the arm angle is not perpendicular to the chest and (B) when the angle of the arm is perpendicular to the chest, for example, in the case of A And B, the offset height is different, and the height of the offset peak of the reference axis (chest-to-thoracic heart direction) can be measured to be larger in the case of B than in case of A. At this time, the height of the offset maximum point represents the distance of movement of the main unit 101 in the direction of the reference axis through the chest compressions, through which the sensor unit 1011 can estimate the arm angle of the chest compressor. In another example, the sensor unit 1011 may measure the offset value of the axis other than the reference axis in case of A, or may estimate the angle of the arm in the operation of performing chest compression through the offset variation between different axes .

The information generating unit 1012 can generate accuracy information based on the height of the highest peak of the offset to be measured, the estimated angle of the arm, and the like or whether the chest compressions are correctly performed.

Referring to step S402, the sensor unit 1011 may estimate the frequency and period of the chest compressions using the measured values or the patterns of the signals measured during CPR or chest compressions. More specifically, the number of chest compressions can be measured based on a pattern of 6-axis acceleration signals or a signal measurement period. On the other hand, the information generating unit 1012 may generate information on whether or not the chest is pressed at the correct period based on the measured number of times of chest compressions.

The light source operation unit 1013 can operate the light source based on the generated information. A plurality of light sources having different colors are located in the main unit 101. The light source operation unit 1013 can operate a plurality of light sources having different colors and when the pressing depth is included in the first threshold range , It is possible to operate both the first color light source and the second color light source when the first color light source is operated and the pressing depth is included in the second threshold range. Further, the light source operating portion 1013 can light some of the plurality of light sources according to the pressing depth, and in this case, the number of the portions may be different depending on the pressing depth. In this case, the first critical range and the second critical range may be determined based on at least one of the age or gender of the subject of chest compressions.

For example, the light source operating portion 1013 may estimate the depth of the chest compressions to quantify the parameters associated with CPR. At this time, the light source operation unit may perform a double integration based on at least one of the pressing depth, the pressing direction, and the pressing speed measured by the sensor unit 1011, or by performing regression equation modeling according to the correlation between the pressing speed and the pressing depth, It is possible to estimate the depth at which the user presses the chest, and to operate a plurality of light sources based thereon. The performer can estimate the compression depth through the light source being operated and can determine whether the chest has been pressed to the correct depth.

In another example, the light source operating portion 1013 can be provided on both sides of the main unit 101, so that the chest compressing can be performed more accurately by confirming the light source in which the performer performing the chest compressing is operated. At this time, the light source is provided in at least three colors and may include a plurality of light sources. More specifically, when the information generating unit 1012 judges that the accurate chest compressions have not been performed based on the measurement result of the sensor unit 1011, the light source is lit in red, and when accurate chest compressions are performed, A plurality of light sources including green light sources may be illuminated green. In other words, when precise chest compressions are made, multiple red, yellow and green light sources may be stacked and lighted.

In another example, the light source operating section 1013 may light a plurality of light sources based on the measurement result of the sensor section 1011. [ For example, when the light source operation unit 1013 determines that the chest compressing depth of the information generating unit 1012 exceeds the predetermined threshold value based on the measurement result of the sensor unit 1011, and the accurate chest compressing has not been performed , It can be lit in red. In this case, the red light source may be stacked on the green light source, and the red light source stacked on the green light source may be a light source different from the red light source described above. In other words, when the depth of the chest compressions exceeds a predetermined threshold, at least one or more red, yellow, green and red light sources may be stacked and lighted.

In another embodiment, the light source operating section 1013 can operate the light source based on other information besides the depth information of the chest compressions. For example, if the remaining amount of the battery of the chest compression assisting device 10 is 30% or less, a warning signal indicating that the chest compression assisting device 10 should be charged may be displayed in yellow. In this case, the yellow light source may be lit for two minutes at intervals of one hour, but is not limited thereto. This makes it possible to transmit the information about the chest compression to the chest compressor simply and accurately, thereby making it possible to more effectively perform CPR or chest compressions.

The operation of the light source operation unit 1013 will be described in detail with reference to FIG. 5 is a diagram showing the operation of the light source operating unit according to one embodiment of the present invention. Referring to FIG. 5, S501 to S505 show light sources operated by the light source operating unit 1013 according to the chest compression depth. The information generating unit 1011 judges that chest compression is performed correctly when the movement from 4 cm to 6 cm from the reference position to the patient's heart is measured from the sensor unit 1011. The light source operation unit 1013, . That is, when the position of the light source operating unit 1013 changes from 4 cm to 6 cm under the same condition as the initial step S501, it is determined that accurate chest compressions are performed and the light source can be operated as in step S505. The light source may be operated in the form of a stack of red, yellow, and green. This allows the practitioner to visually confirm that the current chest compressions were performed correctly. The light source operating portion 1013 can operate the light source in addition to the chest compression depth, even when the chest is pushed in the correct direction based on the pressing direction or the like.

On the other hand, the light source operating portion 1013 controls the number or color of the light sources to be operated in the case of the first pressing depth and the first pressing direction to the number or color of the light sources operating in the case of the first pressing depth and the second pressing direction You can do it differently. For example, the light source operating section 1013 can operate the color or the number of the light sources to be operated differently when the chest compression direction is not correct even when the chest compression depth is correct. More specifically, when the chest is pushed in the direction corresponding to 30 degrees with respect to the cardiac direction, rather than pushing the subject's chest as the reference position in the cardiac direction, the light source is operated as shown in S502 to S504 of Fig. 5 .

The communication unit 1014 can transmit the information to the external device 20. [ The communication unit 1014 may transmit the current position of the user to the external device 20 while the user performs chest compressions. The external device 20 may be comprised of a mobile device communicatively coupled to at least two or more chest compression assist devices 10. For example, the communication unit 1014 can transmit information on the current position to the external server or the external device 20 when an emergency patient occurs, and in another example, the communication unit 1014 can measure If the number of chest compressions is measured 30 times or more, the current position may be transmitted to the external server or the external device 20 so that the emergency rescue team can receive the location information of the emergency patient. In this case, the communication unit 1014 may be provided so as to directly communicate using a mobile communication network, a Wi-Fi, or the like. The communication unit 1014 may communicate with the external device 20, which is provided by Bluetooth and performs chest compressions, Device 20 and a server. In this case, a separate application can be installed and used in the mobile terminal.

In another example, the communication unit 1014 may transmit information related to chest compressions to the external device 20 while the user performs chest compressions. For example, when an emergency patient is present, the communication unit 1014 transmits information related to chest compressions to the external device 20 when the number of chest compressions measured by the sensor unit 1011 is 30 or more, The external device 20 may transmit the current position measured by GPS or the like provided in the external device 20 to an external server or a separate device so that the emergency rescue team can receive the location information of the emergency patient.

The communication unit 1014 may be designed as a Bluetooth-based wireless communication circuit for data synchronization between the chest compression assisting device 10 and the external device 20 such as a smart device application. A virtual network using a dummy file can be constructed to form a wireless network based on the Bluetooth communication, power consumption can be minimized by using a Bluetooth low power profile, and a plurality of chest compression assist devices 10 can be connected to an external device 20 Network. ≪ / RTI >

In more detail, the communication unit 1014 may be coupled to an external device 20 that performs monitoring and analysis of parameters related to CPR or chest compressions measured through the chest compression assist device 10. In this case, the external device 20 may perform monitoring and analysis through the smart device application installed in the external device 20. [ The communication unit 1014 transmits information on the five CPR evaluation qualities to the external device 20, and the external device 20 can monitor the CPR. The five qualification criteria may be, for example, compression rate, level of compression, correct relaxation after compression, exact compression axis, frequency and length of compression interruption.

The external device 20 according to an exemplary embodiment of the present invention may perform a database function for storing the medical record in the device, store the CPR time for generating a report after the CPR, Feedback and CPR-related research materials. Also, the external device 20 can build or test a virtual sensor network using a dummy file. The mobile application can access the database, and the initial dummy file can be used to construct or test the virtual sensor network to send and receive data.

The switch 1015 may receive user input to begin providing information related to chest compressions. For example, the switch 1015 may allow the user to operate the chest compression assisting device 10 and may comprise a button. However, the switch may be provided with a touch screen so as to simultaneously perform input and output, but the present invention is not limited thereto.

The information generating unit 1012 sets the position of the sensor unit 1011 to the reference position and outputs the measurement to be measured by the sensor unit 1011. In the case where the chest compression assisting device 10 is operated through the switch 1015, Information can be generated based on the value. In other words, the position of applying power to the chest compression assisting device 10 through the switch can be the reference position.

The switch 1015 may change the first threshold range and the second threshold range based on one of the age or gender of the subject of chest compressions when a predetermined type of operation is input. For example, when the switch 1015 is pressed twice quickly, the mode can be changed, and there may be a mode having various threshold ranges depending on the age range or gender of the patient.

The sound output unit 1016 may output sound that guides the compression of the chest during the process of performing the chest compression by the user. For example, the sound output unit 1016 may perform an alarm to notify the user of the CPR cycle recommended in the CPR, and provide a periodic alarm to inform the user of the recommended CPR cycle It can be designed in the form of a buzzer.

In another example, the sound output unit 1016 is provided with a speaker and can output sound 30 times at a rate of 100 to 110 times per minute. The user can perform chest compressions in accordance with sounds output through the sound output unit 1016. [ The sound output unit 1016 outputs a sound of a predetermined rhythm so that the chest compressions can be performed 30 times during the CPR operation. Also, the sound output unit 1016 may output a sound capable of performing artificial respiration, and the artificial respiration sound may be output so as to last for 1 second and repeat the silence twice for 2 seconds. The artificial respiration sound may be provided to be output after the compression of the chest is finished, and the sound of the chest compression and the sound of the artificial collar may be provided in different sounds or sounds.

Although not shown in the drawings, according to various embodiments of the present invention, the chest compression assisting device 10 may further include a GPS (not shown), an LED counter (not shown), and an optical sensor (not shown).

GPS can grasp the current position of the user, more than two GPSs for accuracy of position measurement, and more precise information can be obtained by offsetting the common positions of GPS using two or more GPSs located close to each other It is possible. Thereafter, it is possible to obtain the corrected position information by comparing with the position information received from another GPS.

The LED counter can indicate the number of chest compressions. More specifically, when the user performs accurate chest compressions, there is an effect that information on the number of chest compressions performed by the user can be obtained by outputting information through the counter LEDs. The counter LED can also indicate the time.

The optical sensor is a sensor capable of monitoring the wearer himself wearing the chest compression assisting device 10, and can monitor the occurrence of an anomaly to the wearer so as to generate information. That is, the optical sensor senses the pulse of the user and transmits the information to the external device 20 through the communication unit 1014 or the sound output unit 1016 when the pulse is measured above or below a preset value So that the wearer can ask for help in case of an emergency. An example of the optical sensor is an infrared sensor, which can monitor a user's pulse, but is not limited thereto.

According to various embodiments of the present invention, the external device 20 may be another chest compression assist device. Other chest compression assisting devices may be worn on the body part of the second user and other chest compression assisting devices may be operated using information generated in the chest compression assisting device 10. [ For example, in performing cardiopulmonary resuscitation, if there are more than two performers, information associated with the CPR generated at the first user's chest compression assist device 10 may be shared by the second user's chest compression assist device , It is possible to perform a smooth CPR operation.

In this case, the communication unit 1014 receives external information from another chest compression assist device, and the information generating unit 1012 receives external information from the other chest compression assist device You can generate information related to chest compression or CPR. In this case, the other body part may be, but not limited to, a part of the user's left and right wrists.

In other words, the chest compaction aid device 10 may be operated by sharing information between two or more users and sharing information with each other, and may be operated by sharing information with two or more parts of one user's body have.

In addition, according to one embodiment of the present invention, the chest compression assisting device 10 may receive and store external information from the external device 20. [ For example, when the external device 20 is a CPR pad for guiding the execution of the CPR operation, the user can perform chest compressions using the CPR pad attached to the subject's body, And the information generating unit 1012 may generate information related to compression of the chest or CPR in consideration of external information. The chest compression assisting device 10 may store the received external information. The external device 20 may be an Automated External Defibrillator (AED), but is not limited thereto.

6 is a flowchart illustrating a procedure of chest compression according to an embodiment of the present invention. Referring to FIG. 6, in step S601, the chest compressing operator performs a CPR on the patient's palm heel in the center of the patient's chest and touches the switch 1015 of the chest compression assisting device 10 Can be pressed. In this case, it is possible to change to the adult and infant mode in accordance with the age range of the patient, and the mode change can be changed by quickly pressing the switch 1015 twice.

In step S602, voice guidance for CPR is output, and the performer can periodically press the subject's chest about 5 cm in the cardiac direction.

In step S603, the sound guiding compression of the chest compression assisting device 10 can be output 30 times at a rate of 110 times per minute, and the user can periodically press the chest with information to be pressed at a depth of about 5 cm in accordance with the beat . The chest compression assisting device 10 may transmit the current position to the networked smartphone during fifteen presses during the thirty presses, and the rescue request to the thumbnail 119 upon thirty presses. On the other hand, the performer can confirm the accuracy of chest compressions by watching the light source operated on the chest compression assist device 10 in performing chest compressions. The light source may be raised so that the plurality of light sources become green when correct chest compression is performed, which is 4 cm to 6 cm in depth in the cardiac direction with respect to the chest of the subject. If the light source is operated in red, it can be confirmed that the correct chest compressions are not made. On the other hand, the chest compaction assisting device 10 can count the time and number of times when correct chest compressions are performed while 30 alarms periodically come out.

In step S604, the sound that ends the 30 beeps and notifies the artificial respiration lasts for 1 second and then becomes silent for 2 seconds. Sounds that announce artificial respiration can come out twice. At this time, even when chest compression is performed without artificial respiration, the number of pressing times can be recorded. The performer can perform artificial respiration according to the sound of artificial respiration. At this time, if the depth or pressure cycle of the chest compressions is out of the normal range, a feedback message may be output via the sound or display.

After the sound for notifying the artificial respiration is terminated in step S605, the note is changed to a note informing the chest compressions, and the performer can resume chest compressions based on this. In step S606, the chest compression assisting device 10 may repeat the operations of steps S603 to S605 until termination through the switch 1015, and the performer may perform CPR based on the guidance sound. When the CPR or chest compressions are completed in step S607, the operation of the device can be stopped by operating the switch 1015 of the chest compression assisting device 10, and the start time, end time, The number of times and the recording graph, and the like can be transmitted. The user can record on the hospital recording sheet based on the transmitted information.
