The CPR training device according to one embodiment is installed inside the human body model for CPR training, and may include a pressure pad, an artificial respiration measurement module, and a control module. The CPR training device is configured to use at least one required unit of the pressure pad and the breathing measurement module in association with the control module in accordance with the training purpose and the human body model structure, Training, monitoring and the like.
The compression pad is a unit for providing the compression mode of the CPR training apparatus and can be mounted on the sternum in the thoracic region inside the human body to provide sensed data measurement in the compression mode and real time feedback information therefrom. The pressing pad senses a pressing action through sensors that measure acceleration, position, and force with respect to a pressing force applied by a user. The acceleration value by the pressing increases and the depth measurement value of the force sensor reaches a predetermined depth If it is above the threshold value, it can be judged as the pressing mode operation irrespective of the result value of the remaining sensors.
The artificial respiration measurement module is a unit for providing the respiration mode of the CPR training apparatus. The artificial respiration measurement module may be connected to the artificial lung of the human body model to provide sensed data measurement in respiration mode and real time feedback information. Wherein the ventilation measurement module measures respiration activity through an air pressure sensor unit that measures whether the user blows in air, and when the respiration amount corresponding to the air pressure measurement value of the air pressure sensor unit by the respiration action is equal to or greater than a predetermined respiration threshold, It is possible to discriminate the breathing mode operation regardless of the result of the sensors.
The control module may be connected to at least one of the pressure pad and the ventilation measurement module to supply power to the pressure pad and the artificial respiration measurement module.

In the CPR training device, when the pressure action and the breathing action by the user are simultaneously detected, the CPR training device determines whether the sensed data measured by each sensor is equal to or greater than a threshold value for each sensor, have. However, when both the pressure pad and the sensor data included in the respiration measurement module are measured above the threshold value, the pressure mode or the breathing mode can be determined by giving priority to each sensor. For example, if the magnitude of the input measured by the force measuring sensor is greater than the threshold pressure and the acceleration measured by the acceleration measuring sensor is greater than or equal to the critical acceleration in the direction of action of the pressure, The pressure mode can be selected during the breathing mode. In addition, the ventilation measurement module may correspond to at least one of a case where the pressure measured by the force measuring sensor is less than a critical pressure and a case where the acceleration measured by the acceleration measuring sensor is less than the critical acceleration in the direction of the pressure, If the measured air pressure value is above the threshold air pressure, the control module can determine the current measurement state as the breathing mode during the compression mode and the breathing mode.

FIG. 9 is a flowchart illustrating a process of breathing mode according to an embodiment.
The artificial respiration measurement module senses respiratory action through an air pressure sensor unit that measures a change in air pressure in an artificial lung due to inflow of air blowing by a user. The pressure applied to the pressure pad is less than a critical pressure, It is possible to determine that the breathing mode operation is performed when the breathing amount corresponding to the air pressure measurement value of the air pressure sensor unit due to the breathing action is less than the critical acceleration in the action direction of the pressure and is equal to or greater than a predetermined breathing threshold value. The artificial respiration measurement module has a cycle of periodic reduction and expansion after being first bounded to an artificial lung. The sensory data of the atmospheric pressure-breathing amount estimation module is used to estimate the expansion and contraction of the artificial lung And the respiratory volume information corresponding to the respective breathing volume. For example, when the artificial lung expands according to breathing, the respiratory state is determined according to the amount of respiration, and when the artificial lung is reduced, respiration relaxation information can be discriminated.
In
In
In the respiration mode, normalization (for example, 1-100) is performed on the breathable amount detectable section from the atmospheric pressure-respiratory volume data of the human body model obtained from the sample data of the correction data, and this interval is divided into three sections (WEAK) in which the respiration amount due to the measured pressure is less than the effective period and the respiration amount due to the measured pressure exceed the effective period based on the effective breathing amount interval (GOOD) "STRONG"). In this case, an interval corresponding to a certain portion (for example, 10% to 15%) is designated as a breathing threshold value so as to efficiently identify the breathing action while reducing errors caused by unnecessary sensing data, The module determines the respiratory volume information according to the respiratory infusion cycle in which the breathing air is repeatedly introduced into the human body model.
10 is a flowchart illustrating a sensing data correction process in a compression mode and a breathing mode according to an embodiment.
During the compression of the thorax, the magnitude of the force applied to the pressure pad through the force sensor is measured, which is corrected to the pressure depth value by the force-depth prediction function, It can be used in programs. Similarly, during artificial respiration on the anatomical model, the air pressure value due to the air entering the artificial lung is measured through the air pressure sensor, which is corrected to the respiratory volume value by the air pressure-respiration prediction function, It can be used for training and test programs.
When the sensing data correction in the compression mode or the breathing mode is started in

However, if it is determined that the existing correction data is not utilized as a result of the determination, the process of generating new correction data suitable for the training apparatus linked to the current human body model may be sequentially performed. In this case, new correction data is generated in

However, if it is determined that the user does not satisfy the test result for the correction data, the correction data may be modified through step 1071. In the modification process of the correction data, And changing the slope of the linear function corresponding to the data. In the correction data modification process of step 1071, the correction data can be simply modified without additionally collecting new trial data by directly adjusting the slope of the linear function for the correction data. 11, the initial force-depth linear prediction function (or the atmospheric pressure-respiration amount prediction function) obtained by the user based on the repeated execution data is expressed as the slope a 1110, If the depth value (or the amount of breath) is desired to be corrected, the correction data can be corrected in such a manner that the inclination is decreased toward the inclination a '1120 or the inclination is increased toward the inclination a' '1130.

16 is a view for explaining a process of providing feedback when interfacing with a CPR training apparatus according to an embodiment.
When the CPR training device operates in the compression mode, the pressure pad attached to the chest of the human body measures an acceleration value change with respect to the gravity direction of the pressure using the acceleration measurement sensor unit, It can be determined whether it is pressed or depressed by an action or is released and released. The pressing position can be determined according to whether or not the pressing depth measured by the pressure applied to the pressing pad is equal to or greater than a predetermined depth threshold.
If the measured pressure value does not exceed the depth threshold value, the position measurement sensor unit disposed at the inner edge of the pressing pad detects a wrong pressing position from the user's mobile device linked to the CPR training device And provide user feedback in real time. At this time, the position measurement sensor unit reflects on / off detection results of the switch sensors uniformly arranged in the front, rear, left, and right directions of the inside of the pressing pad, The direction with the most turn-on result among the four directions of the right / wrong direction can be determined as the wrong pressing position. The feedback information on the wrong pressing position may be provided as a
If the current pressing depth value measured through the force measuring sensor unit mounted at the center of the pressing pad exceeds the depth threshold value, the pressing position of the user sensed by the position measuring sensor unit becomes the normal pressing position It is judged whether or not it is not. As a result of the determination, if the pressure depth measurement value is greater than or equal to the maximum depth value, the maximum depth value is updated. If the pressure depth measurement value is less than the maximum depth value, In other words, it can be determined that the downward movement -> the upward movement). (Where the initial maximum depth value is set to a sufficiently low value and the initial position is set to zero)
If the maximum depth value is smaller than the start point of the effective compression depth section, it is determined that the compression depth due to the current pressure does not fall within the effective range, and the maximum depth value is determined as the start point of the effective compression depth section And if the maximum depth value is less than or equal to the end point of the effective compression depth section, it is determined that the compression depth by the present pressure exceeds the effective range. If the maximum depth value is less than or equal to the end point of the effective compression depth section, It can be judged as a 'GOOD' state in which the pressing depth by the pressure is within the effective range. The force sensor measuring unit may transmit sensing data about the pressing depth to a user's mobile device linked to the CPR training device to provide user feedback in real time. Feedback information on the pressing depth is provided as a three-
When it is determined that the pressing position of the user sensed by the position measurement sensor unit is the normal pressing position and the current acceleration measurement value is not the normal pressing position and the current acceleration measurement value is greater than the maximum acceleration value, , And if the current acceleration value is less than the maximum acceleration value, it can be determined that the direction of motion caused by the pressing is changed (for example, descending motion -> upward motion).
And it is possible to determine whether the pressing position of the user sensed by the position measuring sensor unit is the normal pressing position, when it is determined that the pressing pad is lifted and the pressing pad is relaxed. As a result of the determination, if the current depth measurement value is less than the minimum depth value, the minimum depth value is updated. If the current depth measurement value exceeds the maximum depth value, In other words, it can be judged that the upward movement -> the downward movement). If the current depth value and the minimum depth value are greater than a predetermined depth threshold, it is determined that the compression relaxation is not normal. If the current depth value or the minimum depth value is less than or equal to the depth threshold value, If both the position / normal pressure depth / normal pressure relaxation is achieved, it is possible to initialize the relevant parameters after the final determination that the correct compression has been achieved comprehensively. However, if at least one of the normal pressing position, the normal pressing depth, and the normal pressing relaxation is not performed, only the initialization of the related variables proceeds without any discrimination about the pressing. Feedback information on the determination of the relaxed state may be provided as a
If it is determined that the pressing position of the user sensed by the position measurement sensor unit is the normal pressing position, if it is determined that the pressing position is not the normal pressing position, the minimum acceleration value is updated if the current acceleration measurement value is less than the minimum acceleration value If the current acceleration value exceeds the minimum acceleration value, it can be determined that the direction of motion due to the pressing is changed (for example, the upward movement-> the downward movement).
In the case where the CPR training apparatus operates in a breathing mode, the respiration sensing unit of the artificial respiration measurement module, which is fastened to the artificial lung, measures the atmospheric pressure of the artificial lung using the air pressure sensor unit, It is possible to judge whether or not it is inflated by the action. If it is determined that the artificial lung is inflated, if the current breathing amount of the artificial lung is equal to or higher than the highest breathing amount, the breathing amount according to the current air pressure is updated to the highest breathing amount. If the current breathing amount is less than the highest breathing amount, (Ie, expansion -> contraction). (Here, the initial upper respiratory volume is set to a sufficiently low value)
If the maximum respiration amount is less than the start point of the effective respiration amount interval, it is determined that the respiration amount due to the current air pressure does not reach the valid period. If the maximum respiration amount is equal to or more than the start point of the effective respiration amount interval, STRONG "state in which the volume of breathing due to the current air pressure exceeds the valid interval if the breathing volume is greater than the ending point of the breathing volume section, and if the breathing volume is less than or equal to the ending point of the effective breathing volume section, It can be judged as 'GOOD' state.
If the artificial lung is judged to be reduced, it is judged that the direction of movement by breathing is changed (for example, miniaturized motion - > inflation motion) if the amount of respiration based on the current air pressure is below a predetermined respiratory threshold, Can be initialized. However, if the respiration amount due to the current air pressure exceeds the respiration threshold value, the artificial lung is in a state of being reduced, so that no processing is performed (idle).
