4A and 4B are conceptual block diagrams of a CPR training apparatus according to an embodiment, FIG. 4A is a CPR training apparatus 400, and FIG. 4B is a detailed configuration of the training apparatus 410 among the CPR training apparatuses, respectively. City.

First, the cardiopulmonary resuscitation training apparatus 400 of FIG. 4A may have a cube-shaped portable size. In addition, the training device 400 provides training information and training programs for CPR training, and the configuration includes a training device 410 which is an electronic device, and a packaging box used as a packaging and / or auxiliary teaching aid to accommodate the training. . The packaging box may include a cover part 420 and a body part 430.

The training device 410 is a device that detects a compression operation related to CPR training and measures it with an electrical signal, and provides feedback information corresponding to the measurement result in real time, and may be manufactured in a cube shape. The training device 410 measures the degree to which the compression portion at the top of the device is deformed by a compression operation applied by the user in the vertical direction, and calculates the compression depth, position, strength, speed, etc. based on the measurement result to perform the compression operation It is possible to determine whether or not it is appropriate. The determination result is provided to the user using at least one of visual, auditory and tactile senses as feedback information for the pressing operation. The detailed configuration of the training device 410 will be described in detail in FIG. 4B below.

The cover part 420 may be understood as a top cover of the packaging box accommodating the training device 410, and has a hexahedral shape with one side open. Cardiopulmonary resuscitation education information may be printed on at least one outer side surface of the cover part 420.

The body part 430 is covered with the cover part 420 and is a lower supporter surrounding the training device 410, and is manufactured in a folding structure. When the body portion 430 is unfolded, it has a plate shape of a two-dimensional plane, and is folded into a hexahedral shape with one side open according to a predetermined guide fold line to surround the training device 410 to become a cube shape. Covered by the cover portion 420 is to form a packaging that accommodates the training device (410). When the body portion 430 is unfolded, a picture of a person's body shape may be printed in a direction in which the training device 410 is placed in the plate shape, and the picture of the body shape is utilized for CPR training. The configuration and utilization of the body portion 430 are as described above with reference to FIGS. 1, 2A, 2B, and 3A.

Meanwhile, referring to FIG. 4B, the training device 410 of the CPR training device is a means for detecting a user's compression action and providing feedback information on it using at least one output channel. 411, a processor 412, and a feedback unit 413.

According to one embodiment, the pressing unit 411 may be deformed by receiving the pressing applied in the vertical direction. The compression unit 411 is a module that receives a compression action applied by a user in a vertical direction, and a compression action and a relaxation action according to a user's CPR training should be distinguished. To this end, the compression unit 411 includes an elastomer material (for example, urethane sponge material, spring material, etc.) capable of providing elastic force in a direction against the compression while the user gently performs CPR training. While having the elastic force required for chest compressions (e.g., but not limited to, an elastic force of 25 kgf to 30 kgf for 5 cm compression) similar to the actual human chest strength, the force after chest compression is applied. Restoration speed can be maintained even at a compression speed of about 100 times per minute for the property to be released immediately. The pressing portion 411 is configured to enter a depth of about 2/3 of the entire height of the pressing portion when pressing to give an effect similar to physically pressing a person. For example, when the height of the pressing portion 411 is 9 cm, the actual entering depth by the user's pressing operation is implemented to be 5 to 6 cm. Of course, this depth may be set differently in consideration of various factors such as the purpose of education, the age and gender of the target person. Thus, examples of physical values of compression depth or elasticity / restore force should not be understood as limiting the scope of the invention to such examples.

On the other hand, the pressing unit 411 may accommodate a pressing plate and a supporting plate on the inner or outer top to recognize the pressing operation of the user. The pressing plate is a flat plate structure accommodated inside the upper end of the pressing portion 411, and transmits a firm feeling similar to an actual chest to a user's hand applying pressure, and at the same time induces pressure information to be transmitted uniformly. The support plate is a structure that binds between the pressing plate and the feedback portion 413 inside the pressing portion 411, and supports the pressing information transmitted from the pressing plate to be transmitted to the feedback portion 413. At this time, the base plate may include a hole in the central area, the pressure information is transmitted to the feedback unit 330 through the hole, the depth, position, strength, speed, etc. deformed by the pressure of the user Can be measured.

According to one embodiment, the hole formed between the pressing plate and the base plate is formed in a cylindrical shape that widens toward the lower portion (direction of the base plate), so that the structure of the training device 410 does not twist sideways when pressure is applied. It can help to contract in the vertical direction. Therefore, this structure allows the user to induce an accurate compression direction and to enable stable compression training. In addition, due to the structure widening toward the bottom, it is possible to easily check the visual feedback generated in the lower feedback section 413 even in the upper direction.

The processor 412 measures the degree of deformation of the pressing portion 411 by the pressing in at least one of a TOF method, a light quantity measuring method, a magnetic force measuring method, and a load measuring method, and based on this, corresponds to the pressing At least one compression information among depth, position, intensity, and velocity may be calculated.

However, the method in which the processor 412 measures the degree of deformation of the compression unit 411 is in combination with or instead of the TOF method or the light amount measurement method, a triangulation method using a reflection angle, and a magnetic force measurement method using a magnetic force sensor. And a load measuring method using a load measuring sensor, according to various embodiments. In the case of using a triangulation method using a reflection angle, the pressure information may be calculated by outputting the angle of the light emitted from the IR light emitting unit to the pressing plate and returning to the IR light receiving unit as a voltage. In one embodiment, the processor 412 calculates the compression information by comparing information of incident light incident through the air gap provided in the compression unit 411 and information of reflected light from which the incident light is reflected and returned. When measuring the degree of deformation through a TOF method, the processor 412 may calculate the pressure information by comparing an input wave incident through the air gap portion and a reflected wave returned by the input wave reflected by the pressing plate. Here, the incident wave and the reflected wave may be infrared rays, ultrasonic waves, lasers, or the like. In addition, when measuring the deformation information through a light amount measurement method, the processor 412 calculates the pressure information by comparing the intensity of incident light incident through the air gap and the intensity of reflected light from which the incident light is reflected and returned. Can be. In the case of the input method, the pressure information can be calculated by receiving the pressing force from the pressing portion by the pressing plate.

The feedback unit 413 may output feedback information on the compression information calculated through the processor 412. To this end, the feedback unit 413 may further include a sensing unit for electrically measuring the degree of deformation of the pressing unit 411, and an output unit for outputting feedback information on the measurement result. The sensing unit includes at least one of an infrared sensor, an ultrasonic sensor, a magnetic force sensor, and a load measurement sensor for directly or indirectly measuring the degree of deformation of the pressing unit 411. In addition, the output unit for outputting the feedback information determined according to at least one criterion of the depth, position, intensity, speed of the pressure information calculated based on the degree of deformation, LED, It includes at least one of a speaker, a buzzer, and a vibration motor.

If the output unit is an LED, a plurality of LEDs are arranged in the feedback unit 413, and the plurality of LEDs sequentially turn on, flash, and change at least one feedback according to the predetermined direction in response to the pressing information. Visual feedback can be implemented. In this case, it is possible to produce an effect visually showing the degree of blood circulation due to the user's pressing action. In addition, visual illuminance can be implemented in a manner that the illuminance of the LED gradually increases and lights up according to the depth of compression.

If the output unit is a vibration motor, tactile feedback may be implemented in a manner of generating a preset vibration pattern in response to the compression information, which has the effect of tactilely creating a heartbeat state by the user's compression action.

If the output unit is at least one of a speaker and a buzzer, it is possible to implement auditory feedback to output whether or not the compression information is appropriate as a beep or click sound. According to some exemplary embodiments, auditory feedback may be implemented by outputting a guide sound that induces an appropriate compression speed during a training process.

The process of the feedback unit 413 outputting feedback information on the compression information may be implemented according to various embodiments. For example, if the depth value corresponding to the compression measured through the sensing unit is greater than or equal to a first measurement value that is a predetermined compression depth criterion, the feedback unit 413 judges normal compression and hears the normal pressure through the speaker. Feedback can be output. In addition, when the depth value measured after the normal compression returns within a predetermined range based on 0, the feedback unit 413 counts the number of normal compressions as determined as a relaxed state, and whenever the normal compression number is counted. Visual feedback can be output via the LED. If the number of LEDs provided in the feedback unit 413 is 20, the LED lights are turned on one by one when the cumulative count of the normal pressing times is 20 times or less, and the cumulative count of the normal pressing times is 20 times. If exceeded, visual feedback may be provided in a manner that provides time difference lighting. In addition, when the cumulative count number of the normal pressing times exceeds a predetermined number of times, the feedback unit 413 may additionally output tactile feedback using a vibration motor. The output method of the feedback information is not limited by any one embodiment, and the feedback information for each item such as depth, position, intensity, speed, number of times of the pressure information measured in response to the user's pressure LED, speaker , It can be provided in various ways in combination with each output means such as a vibration motor.

The training device 410 may be manufactured in a cube shape having a size that can fit in a 10x10x10 cube for easy portability, but can be modified in various sizes in consideration of a difference in the size of each user's hand. The detailed configuration inside the CPR training device 410 will be described in detail with reference to FIGS. 5A to 5E below.

On the other hand, the cardiopulmonary resuscitation training device 400 may further include a communication unit (not shown) so as to interoperate with a user terminal such as a user's mobile device, a PC, or a display device available at a user location. The communication unit may interwork with the user terminal through at least one wireless communication function of Wi-Fi, Bluetooth, or NFC (Near Field Communication), and perform a real-time simulation program or education program related to the feedback information. Can provide.

5A to 5E are diagrams illustrating a detailed configuration of a CPR training apparatus according to an embodiment. 5A is a front view of the cardiopulmonary resuscitation training apparatus 500, and FIGS. 5B, 5C, and 5D show the external and internal side surfaces of the CPR training apparatus 500, respectively. In addition, FIG. 5E shows the internal configuration of the compression unit to which the compression operation is directly applied in the CPR training apparatus 500.

The cardiopulmonary resuscitation training apparatus 500 is largely divided into a compression unit 510 and a feedback unit 520. The compression unit 510 is a portion that is deformed according to the user's compression, and the feedback unit 520 is caused by the compression. While supporting the external force, it can be understood as a part of measuring the degree of deformation of the pressing portion 510 and feeding it back. The pressing portion 510 and the feedback portion 520 have a structure that is easily coupled by an adhesive material (or auxiliary material such as a bolt), and maintains a three-dimensional cylindrical shape or a cube-like shape when no pressing is applied. .

First, the compression unit 510 is a portion that is transformed by receiving the pressure applied by the user in the vertical direction. When the user performs chest compression in the actual CPR process, the compression-relaxation state of an appropriate depth (eg, 50 mm or more) It is configured to experience repeatedly. The pressing unit 510 is a pressing unit housing 511 to which the user's pressing is directly applied, and a pressing plate accommodated in the pressing unit housing 511 to transmit pressing information corresponding to the pressing to the feedback unit 520. It may include a 512 and the base plate 513. The pressing unit housing 511 may be made of a material having elasticity so that the pressing operation and the relaxing operation performed by the user can be clearly distinguished. For example, the compression unit housing is made of an elastomer material (for example, urethane, sponge material, spring material, etc.) so that the user can return to the original shape when the user performs a gently pressing operation while relaxing after the pressing operation. 511 can be produced.

The pressing plate 512 is a flat plate structure that induces pressure information to be transmitted uniformly in the vertical direction while delivering a solid feeling similar to an actual chest to the user's hand applying pressure, inside the upper portion of the pressing part housing 511 Is accommodated in. The support plate 513 is a structure that binds between the pressing plate 512 and the feedback portion 520 inside the pressing portion housing 511, wherein the pressing information transmitted from the pressing plate 512 is the feedback portion ( 520). At this time, the central region of the base plate 513 includes a circular hole, through which the pressure information is transmitted to the feedback unit 520, the depth, position, strength, which is deformed by the pressure of the user, Speed, frequency, etc. are measured. The pressing plate 512 and the supporting plate 513 must have a thickness sufficient to withstand the pressing operation of the user input from the pressing portion housing 511 and to be transmitted to the lower feedback portion 520.

Meanwhile, a hole-shaped air gap portion 516 having a predetermined size is provided in the pressing portion housing 511. The gap portion is gradually narrower from the bottom to the top (the upper end cross-section exhibits a trapezoidal shape), and the pressing portion housing 511 made of a skeleton-free elastomer is compressed in the vertical direction as much as possible by the user's pressure, so that the straightness is achieved. Let it descend with a float (540). In addition, the air gap portion 516 may be used to measure pressure information including at least one of a degree of deformation of the pressing portion 510 and a depth, position, intensity, and speed corresponding to the pressing due to the pressing.

The feedback unit 520 measures the degree of deformation by the user's compression by the compression unit 510 by at least one of a TOF method, a light amount measurement method, a magnetic force measurement method, and a load measurement method, and the compression calculated based on this This is the part that outputs feedback information about the information. The feedback unit 520 is composed of a connection unit 521 and a body unit 522 that are engaged with the pressing unit 510. The connection unit 521 and the body unit 522 include a sensing unit, a processor, And an output unit. The sensing unit measures the degree of deformation of the pressing unit 510 using at least one of an infrared sensor, an ultrasonic sensor, a magnetic force sensor, and a load measurement sensor. The method of measuring the degree of deformation of the compression unit 510 in the feedback unit 520 may be implemented in various embodiments according to the type of sensor provided in the CPR training apparatus 500.

The processor calculates pressure information such as depth, position, intensity, speed, and frequency corresponding to the pressure based on the measurement result of the sensing unit, and determines whether normal compression is performed based on the calculated pressure information. The output unit outputs feedback information for the compression information by using output means such as an LED 531, a speaker 533, and a vibration motor 534 provided outside the side surface of the body portion 522. In addition, the body 522 may further include a means 532 for outputting power or battery status information of the cardiopulmonary resuscitation training apparatus 500 and a wireless communication function supporting interworking with a user terminal.

The pressing part 510 replaces the insert type of the structure in which the pressing plate 512 is inserted as shown in FIGS. 5B and 5C, and may be implemented as a cap type to which the cover 515 is added as shown in FIG. 5D. The cap type is composed of a three-stage structure of the cover 515, the pressing portion 510 and the feedback portion 520 when viewed from the outside. The cover 515 provides a lower tactile hardness with the thorax because the part of the user's hand that is pressed is harder than the pressing plate 512 inserted into the pressing part 510 in the insert type. It helps to press the vertical direction more clearly, and is easy to manufacture according to separation and assembly.

Meanwhile, the compression unit 510 may be manufactured in various ways to give a physical effect similar to that of compressing a human chest. In the course of CPR training, an elastic material compression pad 540 may be added to the top of the compression unit 510 in order to provide an elastic force similar to that of a real person's chest in a direction against the compression action of the user. have. In addition, in order to provide the user with a feeling similar to the hardness of the human chest during compression, a plate 541 may be additionally inserted or attached to the inside or the upper portion of the compression pad, in which case the plate 541 is a human It can feel similar to squeezing the breastbone.

The manner in which the feedback information is provided through the feedback unit 520 may be implemented by various embodiments. For example, if it is determined as a normal pressing operation as a result of measuring the sensing unit with respect to the pressing operation signal, the white LED may be turned on, or the LED brightness may be differentially adjusted according to the pressing depth, intensity, number of times, and the like. If the relaxation operation is not normally performed after the pressing operation, the red LED may be turned on or feedback may be provided through a speaker or a vibration motor. In addition, a hands-off time for the pressing operation signal is set, and if the normal pressing operation is not input for a set time, all of the lit LEDs may be turned off.

6 is a view for explaining the detailed configuration of the feedback unit of the CPR training apparatus according to an embodiment. The feedback unit of the CPR training device is equipped with a processor 610, a sensor 620, and feedback output means 630, 640, 650, as shown in FIG. 6, in order to output feedback information on the pressure applied by the user to the device. Includes PCB board.

In FIG. 6, the depth measurement sensor 620 is a module for measuring the height of the compression unit that is deformed according to the user's compression, and is disposed at a position vertically descending from the central portion of the air gap provided inside the compression unit. The depth measurement sensor 620 is at least one of an infrared sensor, an ultrasonic sensor, a magnetic force sensor, and a load measurement sensor, and at least one of a light quantity measurement method, a TOF method, a magnetic force measurement method, and a load measurement method according to the type of sensor provided In this way, the height change of the pressing portion is measured. The processor 610 calculates compression information including at least one of depth, position, intensity, and speed corresponding to the compression based on the height change of the compression unit measured by the depth measurement sensor 620, and the compression information The feedback output means (630, 640, 650) is controlled to output feedback corresponding to.

The cardiopulmonary resuscitation training device may include auditory feedback output means 630, visual feedback output means 640 and tactile feedback output means 650 to provide various feedbacks such as hearing, sight and tactile. At this time, the visual feedback output means 640 is a method in which one or more LEDs, lasers, and the like are disposed near the edge of the PCB board, and a plurality of pieces are continuously along each side of the cube to provide sequential lighting / flashing or animation effects. It may be deployed. In addition, the auditory feedback output means 630 and the tactile feedback output means 650 may be disposed near the center so that the feedback output is not biased and provided to a specific position. In addition, a power supply unit 660 for supplying power to the CPR training apparatus, and a wireless communication module 670 supporting interworking between the CPR training apparatus and the user terminal may be additionally disposed on the PCB board.

7A and 7B are diagrams illustrating a method of measuring compression information by a cardiopulmonary resuscitation training apparatus according to an embodiment, FIG. 7A is a compression information measurement process using a light quantity measurement method, and FIG. 7B is a compression method using a load measurement method It shows the information measurement process. In FIG. 7A, the CPR training apparatus may measure the height change of the compression unit using a depth measurement sensor in order to measure the degree of deformation of the compression unit by compression applied by the user to the device. The depth measurement sensor 710 may be configured as a set of light receiving units and light emitting units to measure the height change of the pressing unit through the air gap.

The void portion 720 is a space provided between the upper surface of the void portion inside the pressing portion and the base plate inside the pressing portion, and is gradually narrowing from the bottom to the top (the upper end section has a trapezoidal shape). The light emitted from the light emitting part of the depth measurement sensor 710 may be designed to be exposed only to the end of the depth measurement sensor 710 so that it can be reflected by the pressing plate inside the upper end of the pressing part to reach the light receiving part. At this time, in order to prevent measurement errors due to internal reflection, the lower surface of the pressure plate and the upper surface of the base plate are treated with non-reflective materials (for example, using a black matte surface material or painting). It might be. In addition, as described above, since the lower portion of the support plate direction is formed in a wide cylindrical shape compared to the upper end of the pressing plate direction, the structure of the device is prevented from twisting sideways when pressed, thereby allowing the user to determine the correct direction of pressing operation. Can be induced.

In FIG. 7A, the change in height of the pressing portion may be measured through measurement of reflection time in addition to measurement of the amount of light. In this case, an infrared sensor or an ultrasonic sensor may be used as the depth measurement sensor. The time at which infrared rays emitted from the infrared sensor return by being reflected by the pressing plate or the ultrasonic waves radiating upward from the ultrasonic sensor return to the pressing plate. By measuring the return time reflected from the, the position of the pressing plate is calculated.

7B describes a load sensing method that can be used in addition to the measurement method using infrared and ultrasonic waves. Referring to Figure 7b, the cardiopulmonary resuscitation training device using a load detection sensor (eg, pressure sensor, load cell, strain gauge, etc.) to measure the degree of deformation of the compression unit by the user applying pressure to the device Changes in wealth height can be measured. The load detection sensor 740 is disposed at a position vertically lowered from the central portion of the air gap provided inside the compression unit, measures the load force by the compression operation, and converts it to the compression depth to calculate the depth. In the load sensing method, a midcap (mid-) on the top of the support plate 731 and the load sensing sensor 740 is provided so that the load sensing sensor 740 can accurately measure the load force transmitted through the pressing plate. cap, 732) is additionally provided. The mid-cap 732 is coupled or adhered using a bolt or piece at a position between the pressing plate and the supporting plate to connect the pressing portion and the feedback portion of the cardiopulmonary resuscitation training apparatus, and at the same time, the load force applied during pressing detects the load It serves to be intensively delivered to the sensor 740.

In addition, a magnetic force sensing method that calculates the depth of pressure by measuring the intensity of magnetic force by using a magnetic force sensor installed near the base plate and having a material having a magnetic force on the pressing plate may be used in the measurement process of the pressure information. .

8A to 8E are diagrams illustrating a method of outputting feedback information of a CPR training apparatus according to an embodiment. As shown in Figure 8a, when the user applies a compression in the vertical direction to the compression unit 810 of the CPR training apparatus, the shape of the compression unit 810 is deformed. The pressing portion 810 may be made of an elastomeric material capable of providing elastic force in a direction against the pressing so that the shape depending on the pressing state and the relaxing state after pressing can be clearly distinguished. .

When the compression unit 810 is deformed by the compression, the feedback unit 820 of the CPR training apparatus measures compression information corresponding to the compression and outputs feedback information. At this time, the feedback information may be implemented by various embodiments, such as visual feedback of the LED provided on the bottom surface of the cube as shown in FIG. 8A, auditory feedback using a speaker, and tactile feedback using a vibration motor.

When implementing visual feedback using an LED, a plurality of LEDs are arranged in the feedback unit 820 as shown in FIGS. 8B and 8C. The LED (831, 832, 833) is arranged in the inner circumferential portion toward the lower surface from the top plate 821 of the feedback unit 820, as shown in Figure 8b, or using the side board as shown in Figure 8c the outer side of the PCB Erected may be arranged on the side 822 of the feedback unit 820. In addition, in order to increase the diffusivity of the LED light, a material having a high reflectance (840, such as a film type mirror, diffused acrylic, etc.) is additionally arranged on the upper or upper side of the feedback part 820, as shown in FIG. 8D. It may be.

The plurality of LEDs arranged in the feedback unit 820 implements visual feedback in a manner in which the plurality of LEDs are sequentially lit or flashed in a predetermined direction in response to the pressing information. In this case, it is possible to produce an effect visually showing the degree of blood circulation due to the user's pressing action. In some embodiments, one LED is additionally lit whenever the user correctly performs one compression (meaning that the conditions of depth titration and relaxation completion are all met), and in this manner, multiple LEDs are all lit. Afterwards, the LEDs can be controlled so that the user can intuitively recall that blood is circulating as the plurality of LEDs turn and flash sequentially while pressing.

According to another embodiment, the light intensity of the LED is changed according to the compression depth (for example, the light is not turned on in an uncompressed state, and the light intensity increases as the compression approaches an appropriate depth). Or, by using an LED device that can display various colors, the color is displayed differently depending on whether the compression depth is appropriate (for example, it does not light up when the compression depth is 0, and as the depth approaches the appropriate depth, the white light illuminates. It may increase, and visual feedback may be provided in such a way that green light is reached when the proper depth is reached, and red light is displayed when pressure is not reached or exceeded.

When implementing tactile feedback using a vibration motor, a vibration motor 850 is mounted in the inner space of the feedback unit 820 as shown in FIG. 8E, and a plurality of grooves protruding from the inner bottom surface of the feedback unit 820 It is fixed by (823). The vibration motor 850 may implement tactile feedback in a manner of generating a preset vibration pattern in response to the compression information, which has the effect of tactilely directing the heartbeat state by the user's compression action. The vibration motor 850 provides tactile feedback in a simple manner to generate vibration whenever the compression depth due to the compression operation exceeds an appropriate depth, or when a continuous compression operation is effectively implemented in accordance with CPR guidelines Tactile feedback can also be implemented in a way that provides compensation feedback by generating a vibration pattern of the heartbeat.

For example, if it is determined that the user has performed 30 appropriate compression cycles (adequate compression-relaxation) by the user, the feedback unit 820 sets the vibration pattern of the exaggerated heartbeat at least once or more (in FIG. 8E, the center inflection point). As a reference, two short-cycle wave shapes including a steep left slope and a gentle right slope can be repeatedly generated. However, the criterion for providing compensation feedback is not limited, and the shape and cycle of the vibration pattern of the heartbeat can be modified according to the educational scenario and the user's preference.

In the case of implementing auditory feedback using a speaker, intuitive feedback is provided by outputting whether the compression information is appropriate as a feedback sound or outputting a guide sound for inducing appropriate compression. Auditory feedback is divided into a guide sound or a feedback sound according to a preset setting, which is set and changed through the operation of an additional button or switch provided at the outer bottom of the feedback unit 820, or used in conjunction with a training device. It can be set through the application. The guide sound is provided in a manner of outputting a repeating beep sound or metronium 100 to 120 times per minute, and the feedback sound is provided in a way of outputting a beep sound or a click sound corresponding to a user's pressing action.

Meanwhile, the auditory feedback may also be implemented in various ways. For example, if it is determined that the compression depth by the user's compression action is an appropriate depth (5-6 cm), it outputs a high-pitched monotone sound as a positive signal at the moment of compression and fails to reach an appropriate depth or exceeds an appropriate depth. If it is judged, it is possible to output a short-pitched tone sound as a negative signal. In some embodiments, a positive signal is output in an ascending array of negatives when compressing the proper depth, and a negative array is descended when the non-appropriate depth is pressed (meaning that the proper depth is not reached or exceeding the proper depth). It can also output negative signals. In addition, after outputting a high-pitched monotone sound at each appropriate depth compression, audible feedback may be implemented by providing a compensation feedback by outputting a sound in an array of rising sounds when a continuous compression operation is effectively performed by more than one set. .

Furthermore, the CPR training apparatus may provide step-by-step feedback according to the user's education process. In the 'low-level feedback' for acquiring the normal compression depth, whenever the measurement depth due to the user's pressure exceeds the normal depth threshold, a speaker is used to output a voice signal such as a beep or click sound. Provide auditory feedback. The 'mid-level feedback' for the relaxation motion practice after the normal compression depth is acquired further includes a feedback rule that provides an appropriate compensation to the user whenever relaxation is performed completely as a compression cycle after normal depth compression. Can be provided. For example, by outputting a light signal using a visual feedback output means such as an LED whenever the compression cycle is counted, the user is provided with an explicit distinction between the compression state and the relaxation state. In addition, in 'high-level feedback' for repetitive practice of effective compression practice, tactile feedback using a vibration pattern can be additionally provided in order to understand the importance of proper continuous compression and to fully complete a set. have. The method for providing feedback is not limited by any one embodiment, and can be implemented in various ways according to a user's setting.
