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 of the CPR training apparatus, respectively. Illustrated.

First, the cardiopulmonary resuscitation training device 400 of FIG. 4A may have a size such that the appearance is portable in a cube shape. In addition, the training device 400 provides training information and a training program for CPR training, and the configuration includes a training device 410, which is an electronic device, and a packing box used as a packaging and / or auxiliary teaching aid. . The packing box may include a cover part 420 and a body part 430.

The training device 410 is a device that detects the compression motion associated with the cardiopulmonary resuscitation training to measure the electrical signal, and provides feedback information corresponding to the measurement result in real time, it may be manufactured in a cube shape. The training device 410 measures the degree of deformation of the pressing portion of the upper end of the device by the pressing operation applied by the user in the vertical direction, and calculates the pressing depth, position, intensity, speed, etc. based on the measurement result. It can be determined whether or not is appropriate. The determination result is provided to the user using at least one of visual, auditory, and haptic as feedback information on the compression motion. The detailed configuration of the training device 410 will be described in detail with reference to Figure 4b below.

The cover part 420 may be understood as a top cover of a packing box for accommodating the training device 410, and has a hexahedral shape of which one side is opened. CPR training information may be printed on at least one outer side of the cover 420.

The body part 430 is covered by the cover part 420 and is a bottom support that surrounds the training device 410 and is manufactured in a foldable structure. When the body portion 430 is unfolded it has a plate-like shape of the two-dimensional plane, folded in the form of a hexahedron one side is opened in accordance with a predetermined guide fold line to surround the training device 410 is a cube shape, Covered by the cover portion 420 to form a package for receiving the training device 410. When the body portion 430 is unfolded, a figure of a human body shape may be printed in a direction in which the training device 410 is placed in the plate shape, and the figure of the body shape is utilized for cardiopulmonary resuscitation training. The configuration and utilization of the body portion 430 are as described above with reference to FIGS. 1, 2A, 2B, and 3A.

On the other hand, referring to Figure 4b, the training device 410 of the cardiopulmonary resuscitation training device 400 is a means for detecting a user's pressing motion and providing feedback information using the at least one output channel, the compression unit 411, a processor 412, and a feedback unit 413 may be included.

According to one embodiment, the pressing unit 411 may be deformed by receiving a pressing acting in the vertical direction. The compression unit 411 is a module for receiving a compression motion applied by the user in the vertical direction, and the compression motion and the relaxation motion according to the cardiopulmonary resuscitation training of the user should be distinguished. To this end, the pressing unit 411 includes an elastomeric material (eg, a urethane sponge material, a spring material, etc.) that can provide elasticity in a direction against the compression while the user gently performs CPR training. Similar to the chest strength of a real person, the elasticity required for chest compression (exemplarily, but not limited to, 25 kgf to 30 kgf for 5 cm compression), is applied after the chest compression. If left, the restoration rate can be maintained sufficiently even at a compression rate of about 100 times per minute for the relaxing property. The pressing portion 411 is configured to enter into a depth of about 2/3 of the total height of the pressing portion during the compression to give a similar effect to the pressure on the person. For example, when the height of the pressing portion 411 is 9cm, the depth actually entered by the user's pressing operation is implemented to be 5 ~ 6cm. 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 subject. Thus, examples of physical values of compression depth or elasticity / restoration force should not be understood to limit the scope of the present invention to such examples.

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

According to one embodiment, the hole formed between the pressing plate and the support plate is formed in a cylindrical shape that becomes wider toward the lower portion (support plate direction), so that the structure of the training device 410 does not twist sideways when pressure is applied. May help to shrink in the vertical direction. Therefore, this structure allows the user to induce an accurate compression direction and enable stable compression training. In addition, due to the structure that increases toward the bottom, the visual feedback generated in the feedback unit 413 at the bottom can be easily confirmed in the upward direction.

The processor 412 measures the degree of deformation of the pressing unit 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. At least one pressure information among depth, position, intensity, and speed may be calculated.

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

The feedback unit 413 may output feedback information about the compression information calculated by 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 measuring sensor for directly or indirectly measuring the deformation degree of the pressing unit 411. The output unit may output feedback information determined based on at least one of depth, position, intensity, and velocity with respect to the compression information calculated based on the deformation degree, such as visual, auditory, and tactile senses. At least one of a speaker, a buzzer, and a vibration motor.

When 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 illuminance according to a predetermined direction in response to the pressure information. Visual feedback can be implemented. In this case, it is possible to produce an effect of visually showing the degree of blood circulation by the user's pressing operation. In addition, visual feedback can be realized by illuminating the LED with increasing illuminance according to the pressing depth.

If the output unit is a vibration motor, it is possible to implement tactile feedback by 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 operation.

When the output unit is at least one of a speaker and a buzzer, auditory feedback may be implemented to output whether the compression information is appropriate as a beep sound or a click sound. According to some embodiments, auditory feedback may be implemented by outputting a guide sound for inducing a proper compression speed during training.

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

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

The pressing unit housing 511 may be made of a material having an elastic force so that the pressing operation and the relaxing operation performed by the user can be clearly distinguished. For example, the pressing unit housing is made of an elastomeric material (eg, a urethane sponge material, a spring material, etc.) so that the user may smoothly perform the pressing operation and return to the original shape when relaxing after the pressing operation. 511 may be manufactured.

The pressing plate 512 is a flat plate structure that delivers a firm feeling similar to the actual chest to the hand of the user applying the pressure and at the same time guides the pressure information to be uniformly transmitted in the vertical direction. Is accommodated in. The support plate 513 is a structure that binds between the pressing plate 512 and the feedback unit 520 in the pressing unit housing 511, and the pressing information transmitted from the pressing plate 512 includes the feedback unit ( 520 to be delivered. At this time, the central region of the support plate 513 includes a circular hole, the depth, position, intensity, which is transmitted by the pressure information is transmitted to the feedback unit 520 through the hole deformed by the user's pressure, Speed, frequency, etc. are measured. The pressing plate 512 and the support plate 513 should have a thickness enough to sustain the pressing operation of the user input from the pressing unit housing 511 and to the feedback unit 520 at the bottom thereof.

The air gap is narrowed gradually from the bottom to the top (the cross section of the upper end has a trapezoidal shape), and the compression unit housing 511 made of an elastomer without a skeleton is compressed in the vertical direction as much as possible by the user's compression to go straight. To fall down with 540. In addition, the gap 516 may be used to measure compression information including at least one of a degree of deformation of the compression unit 510 and the depth, position, intensity, and speed corresponding to the compression by the compression.

The feedback unit 520 measures the degree by which the compression unit 510 is deformed by the user's compression in at least one of a TOF method, a light quantity measuring method, a magnetic force measuring method, and a load measuring method, and the compression calculated based thereon. This part outputs feedback information about the information. The feedback part 520 is composed of a connecting part 521 and a body part 522 that are coupled to the pressing part 510.

The cap type is composed of a three-stage structure of the cover 515, the pressing unit 510 and the feedback unit 520 when viewed from the outside. The cover 515 provides a lower bodily sensation hardness with the chest because the user's hand is harder when pressed, compared to the press plate 512 inserted into the compression part 510 in the insert type. It helps to press the vertical direction more clearly, and is easy to manufacture according to the separation and assembly.

On the other hand, the pressing portion 510 may be manufactured in various ways to give a physical effect similar to pressing the human chest. During cardiopulmonary resuscitation training, an elastomeric compression pad 540 may be added to the top of the compression unit 510 to provide elastic force similar to the actual human chest strength in a direction against the compression operation 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, the 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 may be It can feel similar to compressing the breastbone.

The manner in which the feedback information is provided through the feedback unit 520 may be implemented by various embodiments. For example, when it is determined that the normal pressing operation is performed 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, frequency, and the like. When 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 may be set for the pressing operation signal, and all of the lit LEDs may be turned off if the normal pressing operation is not input for the set time.

In FIG. 6, the depth measuring sensor 620 is a module for measuring the height of the pressing part that is deformed according to the pressing of the user, and is disposed at a position vertically descending from the central portion of the air gap provided in the pressing part. The depth measuring sensor 620 is at least one of an infrared sensor, an ultrasonic sensor, a magnetic force sensor, and a load measuring sensor, and at least one of a light quantity measuring method, a TOF method, a magnetic measuring method, and a load measuring method according to the type of sensor provided.

7A and 7B illustrate a method of measuring compression information by the CPR training apparatus according to an embodiment. FIG. 7A illustrates a compression information measurement process using a light quantity measurement method, and FIG. 7B illustrates compression using a load measurement method. Each information measurement process is shown. In FIG. 7A, the cardiopulmonary resuscitation training device may measure the height change of the compression unit using a depth measurement sensor to measure the degree of deformation of the compression unit by the pressure applied by the user. The depth measuring sensor 710 may be configured as a light receiving unit and a light emitting unit set to measure the height change of the pressing unit through the gap.

The void portion 720 is a space provided between the upper surface of the void portion inside the pressing portion and the support plate in the pressing portion, and becomes narrower from the lower portion to the upper portion (the upper end portion has a trapezoidal shape). The light emitted from the light emitting part of the depth measuring sensor 710 may be designed to be exposed only at the end of the depth measuring sensor 710 so that the pressing plate inside the upper end of the pressing part may reach the light receiving part. At this time, in order to prevent measurement errors due to internal reflection, the lower surface of the pressing plate and the upper surface of the support plate may be treated with non-reflective material (for example, using a black matt surface material or painting). It may be. In addition, as described above, the air gap portion 720 is formed in a wide cylindrical shape in the lower end of the supporting plate direction compared to the upper end of the pressing plate direction, thereby preventing the user from correcting the structure of the device to the side when pressing the exact direction of the pressing operation Can be induced.

In FIG. 7A, the height change of the compression unit may be measured through the reflection time measurement in addition to the light quantity measurement. In this case, an infrared sensor or an ultrasonic sensor may be used as the depth measuring sensor, wherein the infrared radiation emitted upward from the infrared sensor is reflected by the pressing plate, or the ultrasonic wave emitted upward from the ultrasonic sensor is pressed on the pressing plate. By measuring the time of return from the reflection, the position of the pressing plate is calculated.

In FIG. 7B, a load sensing method that can be used in addition to the measuring method using the infrared rays and the ultrasonic waves will be described. Referring to FIG. 7B, the cardiopulmonary resuscitation training device uses a load sensing sensor (such as a pressure sensor, a load cell, a strain gauge, etc.) to measure the degree of deformation of the compression portion by the pressure applied by the user. You can measure the change in height of the negative. The load sensor 740 is disposed at a position vertically descending from the central portion of the air gap provided in the pressing portion, and measures the load force by the pressing operation, and then converts it to the pressing depth to calculate the depth. In the load sensing method, a mid cap (mid-) is disposed on the top of the support plate 731 and the load sensing sensor 740 so that the load sensing sensor 740 accurately measures the load force transmitted through the pressing plate. a cap 732 is further provided. The mid cap 732 is coupled or bonded by using a bolt or a piece at a position between the pressing plate and the support plate to connect the compression part and the feedback part of the CPR training device, and at the same time, the load force applied when the pressure is detected by the load It serves to be delivered to the sensor 740 intensively.

In addition, a magnetic force sensing method that calculates the compression depth by providing a magnetic material on the pressing plate and measuring the strength of the magnetic force using a magnetic force sensor installed near the support plate may be used in the process of measuring the compression information. .

8A to 8E are diagrams illustrating a feedback information output method of a CPR training apparatus, according to an exemplary embodiment. As shown in FIG. 8A, when the user applies a compression in the vertical direction to the compression unit 810 of the CPR training device, the shape of the compression unit 810 is deformed. The pressing part 810 may be made of an elastomeric material that may provide an elastic force in a direction against the pressing so that the shape according to the pressing state and the relaxing state after the pressing may be clearly distinguished. .

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

When implementing visual feedback using LEDs, a plurality of LEDs are arranged in the feedback unit 820 as shown in FIGS. 8B and 8C. The LEDs 831, 832, and 833 are arranged in the inner circumferential portion from the upper plate 821 of the feedback unit 820 to the lower surface as shown in FIG. 8B, or the outer side surface of the PCB using the side board as shown in FIG. 8C. It can be arranged on the side surface 822 of the feedback unit 820. In addition, in order to increase the diffusivity of the LED light, as shown in FIG. 8D, a material having a high reflectance (840, for example, a film-type mirror, diffusion acrylic, etc.) is additionally disposed on the upper side or the upper side of the feedback unit 820 May be

The plurality of LEDs arranged in the feedback unit 820 implements visual feedback in such a manner that the plurality of LEDs sequentially turns on or flashes in a predetermined direction in response to the pressing information. In this case, it is possible to produce an effect of visually showing the degree of blood circulation by the user's pressing operation. In some embodiments, each time the user correctly performs one round of compression (meaning that both conditions of depth titration and relaxation are met), one LED is additionally lit, and in this way a plurality of LEDs are all lit. Afterwards, the LEDs may be controlled so that the user may intuitively think that the blood is circulated as the plurality of LEDs are turned on and flashed sequentially while pressing.

According to another embodiment, the illumination intensity of the LED is changed according to the depth of compression (for example, the light is not turned on in the uncompressed state, and the intensity of light increases as the compression approaches the proper depth). Or LEDs that can display a variety of colors to display colors differently depending on whether or not the depth of compression is appropriate (for example, when the depth of compression is zero, the light does not turn on, and as the depth approaches the depth of white light, Visual feedback may be provided in such a way that green light is reached when the proper depth is reached, or red light is displayed when the pressure is not reached or the pressure is exceeded.

When implementing the tactile feedback using the vibration motor, the vibration motor 850 is mounted in the inner space of the feedback unit 820, as shown in Figure 8e, a plurality of grooves protruding on 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 an effect of tactilely directing a heartbeat state caused by a compression operation of the user. The vibration motor 850 provides tactile feedback in a simple manner that generates vibration whenever the compression depth caused by the compression operation exceeds an appropriate depth, or when continuous compression motion is effectively implemented according to CPR guidelines. Tactile feedback can also be implemented by generating a vibration pattern of the heartbeat to provide compensatory feedback.

For example, if it is determined that 30 consecutive titration cycles (titration-relaxation) have been performed by the user, the feedback unit 820 may determine at least one or more exaggerated heartbeat vibration patterns (in FIG. 8E, the center inflection point. As a reference, two waves of a short period including a steep left slope and a gentle right slope may be regarded as one beat). However, the criteria for providing the compensation feedback are not limited, and the vibration pattern shape and period of the heartbeat may be modified according to the training scenario and the user's preference.

In 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 proper compression. Auditory feedback is divided into a guide sound or a feedback sound according to a preset, which is set and changed through an additional button or switch operation provided at the outer bottom of the feedback unit 820 or used in conjunction with a training device. Can be set via the application. The guide sound may be provided in a manner of outputting 100 to 120 repetitive beeps or metroniums per minute, and the feedback sound may be provided in a manner of outputting a beep or click sound corresponding to a user's pressing motion.

Meanwhile, the auditory feedback may also be implemented in various ways. For example, if the depth of compression by the user's pressing motion is determined to be an appropriate depth (5-6 cm), a high tone single sound is output as an affirmative signal at the moment of pressing, and the pressure is not reached or exceeds the proper depth. If it is determined, a low tone sound may be output as a negative signal. In some embodiments, the positive signal is output in a rising negative array when the proper depth is pressed, and in a falling negative array when the improper depth is pressed (which means that the depth cannot be reached or exceeds the proper depth). A negative signal can also be output. In addition, auditory feedback may be implemented by outputting a high-pitched sound every time a proper depth compression is performed, and then outputting the sound as an ascending array of sounds when the continuous compression operation is effectively performed more than one set. .

Furthermore, the CPR training device may provide step-by-step feedback according to the user's training process. In the 'low-level feedback' for acquiring normal compression depth, whenever a user's measurement depth exceeds the normal depth threshold, a speaker outputs a voice signal such as a beep sound or a click sound. Provide auditory feedback. The 'mid-level feedback' for practicing the relaxation motion after acquiring the normal compression depth further includes a feedback rule that provides an appropriate compensation to the user whenever the relaxation after the normal depth compression is performed as one compression cycle. Can be provided. For example, a light signal is output by using a visual feedback output means such as an LED every time the compression period is counted, thereby providing a user with a distinction between the compression state and the relaxation state. In addition, 'high-level feedback' for repeated practice of effective compression trials can provide additional tactile feedback using vibration patterns to comprehend the importance of proper continuous compression and to compensate for the complete completion of a set. have. The feedback providing method is not limited by any one embodiment, and may be implemented in various ways by a user's setting.
