FIG. 8 is a view illustrating a cross-section as viewed from a cross section A-A' of the main body of the cardiopulmonary resuscitation simulator device shown in FIG. 7 . Referring to FIG. 8 , the cut surface A-A' of the main body is a cross-section through which the cross-sectional structure of the first force sensing module 130 - 1 positioned in the front can be confirmed. Typically, the first force sensing module 130-1 located at the front transmits the distributed force to the front area among the forces applied to the upper part of the device 100, so ideally, 1/3 of the total force applied to the upper part of the first force sensing module 130-1 As much as the size may be transmitted to the first force sensing module 130-1. However, in the case of the present invention, when the magnitudes of the forces sensed by the first to third force sensing modules 130 - 1 are compared, if they fall within a certain threshold range, the same force may be treated as being sensed. This will be described with reference to a separate drawing.

The substrate mounting plate 121 is exposed under the upper hole 111 of the main body. A controller module 150 may be configured on a lower surface of the substrate mounting plate 121 . Since the outer circumferential surface of the main body is covered by the external part 160 , the upper hole 111 is not exposed to the outside of the CPR simulator device 100 , which is finally assembled. By configuring a groove in the inner upper surface of the exterior part 160 in the same shape as that of the upper hole 111 of the body part, the groove provided on the inner upper surface of the exterior part 160 is in the upper hole 111 of the body part. will be plugged in When the groove provided on the inner upper surface of the exterior unit 160 is inserted into the upper hole 111 of the main body part, even if a force is applied to the top surface of the exterior part 160 , the applied force is applied to the upper part of the housing module 120 . It can be distributed evenly in the The dispersed force may be transmitted to the force sensing modules 130-1 to 130-3, respectively. 8 shows the first transmitted force F1 transmitted to the first force sensing module 130-1. In the same manner, the second transmission force F2 may be transmitted to the second force sensing module 130 - 2 , and the third transmission force F2 may be transmitted to the third force sensing module 130 - 3 . This will be described in more detail below with reference to FIG. 9 .

9 is a view illustrating an exemplary cross-section viewed from the B-B' section of the main body of the cardiopulmonary resuscitation simulator device shown in FIG. 7 . Referring to FIG. 9 , since the two force sensing modules 130 - 2 and 130 - 3 are located at the rear of the apparatus 100 , about 2/3 of the force applied to the upper portion of the apparatus 100 is the second force. It may be distributed and transmitted to the sensing module 130-2 and the third force sensing module 130-3. The second transmission force F2 transmitted to the second force detection module 130-2 is the direction of the force applied perpendicular to the third transmission force F3 transmitted to the third force detection module 130-3, and the magnitude of the force is the same.

10 is a view illustrating an appearance of a cardiopulmonary resuscitation simulator apparatus according to an embodiment of the present invention. Referring to FIG. 10 ( a ), the completed CPR simulator apparatus 100 is surrounded by an exterior part 160 , and the exterior shape may be configured in a heart shape. The CPR simulator apparatus 100 may provide a stable curved surface that can be touched by the user by gripping the hand by processing the central portion of the upper surface to be concave. Referring to FIG. 10( b ), it can be seen that the rear part of the completed CPR simulator apparatus 100 is surrounded by the exterior part 160 , and that the upper edge and the side edge are all rounded. Referring to FIG. 10( c ), it can be seen that the force sensing module 130 is more exposed to the outside than the lower surface of the exterior part 160 . Substantially, the force sensing module 130 is in contact with the installation surface, and when the force is transmitted to the main body by pressing the upper portion of the exterior unit 160, the applied force is dispersed and transmitted to the force sensing module 130, respectively, and the force is sensed A force is sensed by the force sensing module 130 when the equilibrium with the vertical drag forces acting between each of the modules 130 and the installation surface is maintained, and an electric signal may be generated according to the magnitude of the sensed force. Referring to FIG. 10( d ), the three force sensing modules 130 - 1 to 130 - 3 positioned on the lower surface may be configured in less than three or in excess of three. However, preferably, it is possible to detect the direction, magnitude, and position of the hand with the optimal number of parts by configuring three.

11 is a view exemplarily illustrating an example in which an external force F is applied to the upper portion of the cardiopulmonary resuscitation simulator device shown in FIG. Referring to Figure 11 (a), the upper surface of the outer portion 160 is marked with a preferred point where the gripped hand should be located. When a force (F) is applied to the upper surface of the device 100 in a state where the user's hand is accurately positioned at the corresponding point, the position where the force is applied by the coordinate values decomposed by the X and Y axes is the coordinate value on the X-Y plane. can be determined as Referring to Figure 11 (b), when the hand is positioned at the correct position and the force is applied in the correct posture, the applied force F is the first transmitted force (F) to the three force branch modules 130-1 to 130-3, respectively. F1), the second transmission force F2, and the third transmission force F3 may be distributed and transmitted.

In Fig. 11(b), assuming that the installation surface is maintained horizontally, the X-Y plane and the X'-Y' plane maintain a state parallel to each other, and the hand is placed at a predetermined position on this virtual X'-Y' plane. When placed, it is determined that the posture of the hand is correct, and when a force is applied to the correct posture at the corresponding position, the magnitudes of the first to third transmitted forces F1 to F3 are the same or have similar values within a critical difference. If the magnitude of the first to third transmission forces F1 to F3 is constant, it is determined that both the position of the hand and the posture of the user are satisfied for the applied force F. It is transmitted to the terminal 200, and the operation contents are displayed on the application installed in the user terminal 200 by using the information of the transmitted force.

12 is a view exemplarily showing an example in which the force is distributed and transmitted inside the B-B' section of the body part when an external force F is applied to the upper part of the CPR simulator shown in FIG. 10 . Referring to FIG. 12 ( a ) , the cut surface B-B' of the device 100 is cut in the X-axis direction of the device, and it can be confirmed that the horizontal state is made based on the front and rear directions. Referring to FIG. 12(b) , the X1-X2 axis and the X1'-X2' axis are parallel to each other, and the X1-X2 axis is a direction on one side of the installation surface. Preferably, the X1-X2 axes are linear components that can divide the device 100 in half in shape, and are horizontal components to the installation surface. Assuming that the X1-X2 axes are horizontal, if a force F is applied while maintaining the X1'-X2' axes in a horizontal state, the applied force is transmitted to the lower portion and the first to third force sensing modules 130-1 to 130 In -3), the first to third transmission forces F1 to F3 may be sensed.

13 is a view exemplarily illustrating a case in which a user applies an external force to the upper portion of the CPR simulator device in a correct posture. Referring to FIG. 13 (a), the user maintains the horizontality of both shoulders, puts hands on top of each other in a state where both arms are straight, and puts them on the hand position points of the exterior part 160, to apply a certain force (F) You can see that you are in a ready position. Referring to FIG. 13( b ), when the force F applied to the upper part of the device 100 by the user is decomposed into components, it can be expressed as first to third transmission forces F1 to F3 . The first to third transmission forces F1 to F3 dispersed in this way may be sensed by the first to third force sensing modules 130-1 to 130-3, respectively. As shown in Fig. 13(a), a virtual triangle is generated by detecting the position of the hand, the horizontal shoulder, the shape of the arm, etc. by the object detection algorithm, and if the created virtual triangle maintains the isosceles triangle shape, the correct front The posture may be recognized, and the result of CPR performed in this state may be transmitted to the user terminal 200 .

14 is a view exemplarily illustrating a case in which a user applies an external force to the upper portion of the CPR simulator device in an incorrect posture. Referring to FIG. 14 ( a ), the user puts his hands on top of the exterior part 160 in a state in which both shoulders are not kept horizontal and both arms are not straightened, to apply a certain force (F). You can see that you are in a ready position. Referring to FIG. 14(b) , when the force F applied to the upper part of the device 100 by the user is decomposed into components, it can be expressed as first to third transmission forces F1 to F3. The first to third transmission forces F1 to F3 dispersed in this way may be sensed by the first to third force sensing modules 130-1 to 130-3, respectively. As shown in Fig. 14(a), when a virtual triangle is generated by detecting the position of the hand, the shoulder level, the shape of the arm, etc. by the object detection algorithm, the generated virtual triangle cannot maintain an isosceles triangle. Therefore, the current user's posture is recognized as an incorrect posture, and the result of CPR performed in this state is recognized by the apparatus 100 , but the result value is not transmitted to the user terminal 200 . Alternatively, depending on the setting, even the result value executed in the wrong posture may be transmitted to the user terminal 200 , transmitted to the LMS server through the network, and transmitted to the instructor terminal 400 .

However, for the operation of CPR performed in a state where the user's posture is incorrect, a notification signal (light emission, sound, vibration, etc.) is generated to notify the user that the posture is incorrect.

The operation of the CPR learning training system using the CPR simulator apparatus 100 according to an embodiment of the present invention will be described as follows. The first simulator 100 - 1 is interconnected with the first learner terminal 200 - 1 through a device pairing process. The first learner terminal 200 - 1 performs a user authentication procedure to use the first simulator apparatus 100 - 1 . That is, when a user information request is made to the data server 300-1 connected through the network, and the user information is transmitted from the data server 300-1, the corresponding user information is transmitted to the LMS server 300-2 and the corresponding user CPR learning training simulation. At this time, the LMS server 300-2 generates the practice data and transmits it to the first learner terminal 200-1 through the network. Learning and training information (eg, pressure intensity value, etc.) obtained while the user follows the practice data displayed on the first learner terminal 200-1 is transferred to the first learner terminal 200-1 in the first simulator 100-1 and the learning and training information is transmitted to the instructor terminal 400 through the LMS server 300 - 2 or directly through the network, and the instructor gives feedback on the user's learning training information transmitted through the instructor terminal 400 . is generated and delivered to the first learner terminal 200-1 through the network. When the first learner terminal 200-1 displays feedback to the user, the user performs new learning by reflecting the feedback, and the first simulator 100-1 provides new learning and training information (eg, new compression strength value) is transmitted to the first learner terminal 200-1, new learning and training information is transmitted to the LMS server 300-2 through the network, and the user information is updated by transmitting it to the data server 300-1.

17 is a timing diagram exemplarily illustrating an operation process of the CPR education and training system shown in FIG. 16 . Referring to FIG. 17 , the simulator 100 performs device pairing with the learner terminal 200 ( S1701 ). The learner terminal 200 processes the learner login procedure through TCP/IP communication with the server 300 (S1702). The instructor terminal 200 processes the instructor login procedure through TCP/IP communication with the server 300 (S1703). The simulator 100 recognizes the user's CPR operation preparation (S1704). The user posture monitoring processing is processed by the app between the simulator 100 and the learner terminal 200 (S1705). When the user puts his/her hand on the simulator 100 , the position of the hand is recognized and the gesture is recognized for the posture the user takes to identify whether the position of the hand is correct and the motion is correct. The position recognition motion recognition is performed using an image object recognition and motion detection algorithm.

When the hand is correctly placed on the simulator and the operation posture is taken correctly, the simulator 100 acquires information on the magnitude of the force for the user's CPR operation as CPR operation execution information (S1706). The simulator 100 transfers the acquired CPR operation execution information to the learner terminal 200 (S1707-1). The learner terminal 200 transmits the CPR operation execution information to the server 300 through the network (S1707-2). The server 300 transmits the CPR operation execution information to the instructor terminal 400 through the network (S1707-3).

The instructor generates feedback for the learner by using the received CPR action execution information (S1708). The instructor terminal 400 transmits the CPR operation feedback information to the server 300 through the network (S1709-1). The server 300 delivers the CPR motion feedback information to the learner terminal 200 through the network (S1709-2). When the learner terminal 200 displays CPR operation feedback information to the user, the user re-executes the CPR operation reflecting the feedback using the simulator 100 ( S1710 ). The simulator 100 transmits the CPR operation re-execution information to the learner terminal 200 (S1710-1). The learner terminal 200 transmits the CPR operation re-execution information to the server 300 through the TCP/IP network (S1710-2). The server 300 transmits the CPR operation re-execution information to the instructor terminal 400 through the TCP/IP network (S1710-3).

The instructor generates CPR motion evaluation information by executing learner evaluation on the received CPR motion re-execution information (S1711). The instructor terminal 400 transmits the CPR operation evaluation information to the server 300 through the TCP/IP network (S1712). The server 300 records the received CPR motion evaluation information as learning information for the learner (S1713).

Referring to FIG. 18 , when the learner's hand is accurately positioned on the upper surface of the CPR simulator device 100 , the learner terminal 200 visually displays on the display 210 that the user's hand is placed in the correct position, , information about where the hand should be placed on the manikin can be visually displayed together.

19 is a diagram exemplarily illustrating a user interface for providing feedback information to a user by sensing a user's motion, which is another example of the user posture monitoring step shown in FIG. 17 . Referring to Figure 19 (a), the learner terminal 200 captures the user's frontal motion posture, detects the two points (Point_1, Point_2) and the hand position (Point_3) of both shoulders of the photographed user, and these The three points (Point_1 to Point_3) are virtually interconnected to evaluate the accuracy of the learner's frontal posture, and when it is determined that the correct posture is taken, it is visually displayed on the display 210 so that the user's posture is the correct posture can do. Referring to FIG. 19( b ), the learner terminal 200 captures the user's lateral motion posture, detects the photographed user's shoulder point (Point_1) and the hand position (Point_2), and determines whether or not the arm is extended. Recognizes the point (Point_3) connected vertically down from the position of the user's eyes, evaluates the accuracy of the learner's lateral posture by connecting these three points virtually, and when it is determined that the correct posture is taken, the display 210 is displayed on the display 210. The user's posture may be visually displayed so that it can be recognized that the user's posture is the correct posture.
