[0002] Pre-hospital comprehensive trauma first aid refers to timely and effective preliminary treatment of patients after traffic accidents, disaster accidents and other accidental injuries to reduce the mortality and disability rate of patients. However, due to time and space limitations, as well as the uncertainty of patient conditions, pre-hospital first aid personnel often need to have a high level of professional knowledge and skills, as well as the ability to respond in emergency situations.

[0003] The existing pre-hospital comprehensive trauma first aid training simulation system mainly relies on hand sensors to detect the trajectory of the hand, such as the traffic accident pre-hospital comprehensive rescue virtual simulation device and method disclosed in the Chinese patent application No. 202210152784.4, However, the motion trajectory of the hand cannot directly deduce the bandaging effect on the human body, which may lead to the training task being detached from reality.

[0033] The number of times that the output parameter of the photosensitive sensor or photosensitive element changes corresponds to the number of layers of bandaging, and is used to determine whether the number of layers of bandaging is qualified;

[0072] In this embodiment, the training project includes cardiopulmonary resuscitation, and the cardiopulmonary resuscitation includes at least one of chest compression, opening the airway and artificial respiration.

[0073] The rescue information collection module corresponding to the above cardiopulmonary resuscitation project comprises a compression sensor, a head posture sensor 6 and a ventilation detection sensor in sequence.

[0074] The compression sensor is arranged at the chest of the mannequin 1 and is used to detect the compression force, depth and frequency in the chest compression project; for example, Figure 3 and 4As shown, the pressing sensor includes a simulated rib 9 arranged inside the chest of the mannequin 1 and a pressing plate 8, the simulated rib 9 includes a set of elastic metal sheets 91 simulating the C-shaped bending state of the rib shape, and a connecting plate 92 arranged above the elastic metal sheets 91, the C-shaped open end of the elastic metal sheets 91 is connected to the connecting plate 92. A cable 93 is connected to the connecting plate 92, the lower end of the cable 93 extends downward and is fixed to the lower end of the elastic metal sheets 91, for maintaining the bending deformation of the elastic metal sheets 91 in the state without external force, in which state the cable 93 is straightened. The connecting plate 92 is provided with the pressing plate 8, and the pressing plate 8 is provided with a plurality of pressure sensors, the chest compression training is performed by pressing the pressing plate 8, after completing a compression, the elasticity of the elastic metal sheets 91 can reset the pressing plate 8. The plurality of pressure sensors are used to sense the pressing force and the pressing position, and a cable displacement sensor 7 arranged below the pressing plate 8, the cable displacement sensor 7 is fixed inside the mannequin 1, the cable end of the cable displacement sensor 7 is connected to the pressing plate 8, for detecting the change of the displacement amount of the pressing plate 8 during the chest compression training to correspond to the compression depth and frequency. The pressure sensor and the cable displacement sensor 7 transmit the detection signal to the single-chip microcomputer arranged in the mannequin 1, and then transmit the data to the upper computer through Bluetooth. In this embodiment, the structure of the simulated rib 9 simulates the shape of the human rib, compared with the ordinary spring, the resistance feedback can be improved when performing the compression operation.

[0075] The head posture sensor 6 is arranged at the head of the mannequin 1, for detecting the posture information of the head in the open airway project; the head posture is detected by the head posture sensor 6 to judge the completion degree of the open airway project. The sensor for detecting the posture of the object is the prior art, and the angular velocity sensor (gyroscope) can be used.

[0076] The ventilation detection sensing module is arranged in the mannequin 1, and the ventilation detection sensing module includes a simulated airway 5 and a ventilation sensor 4, the simulated airway 5 is communicated with the mouth of the mannequin 1, and the ventilation sensor 4 is used to detect the ventilation in the simulated airway.

[0077] As Figure 3 and 5As shown, in the embodiment, the ventilation sensor includes a gas bag 3 which is in communication with the simulated airway 5, the gas bag 3 is arranged on the connecting plate 92, and the pressing plate 8 is pressed against the gas bag 3, when gas enters the gas bag 3, the pressing plate 8 rises, and the pull wire of the pull wire displacement sensor 7 is pulled out, so as to detect the frequency and the ventilation volume of the ventilation to the mannequin 1 when the artificial respiration training is performed. In an embodiment, the pressing plate 8 is covered in the mannequin 1 by the elastic skin, and after one ventilation is completed, the pressing plate 8 is reset by the elastic force of the skin and / or the gravity of the pressing plate 8 itself. It should be noted that the up-down positional relationship of the pressing plate 8, the pull wire displacement sensor 7, the gas bag 3 and the simulated rib 9 in the embodiment is defined in the posture that the chest of the mannequin 1 is upwardly lying, that is, the chest is upward and the back is downward.

Specifically, the cardiopulmonary resuscitation item further includes a compression-ventilation cycle, and the corresponding action of the rescue operation is the cyclic alternating action of the chest compression and the artificial respiration action. Specifically, the cardiopulmonary resuscitation item includes, in sequence, the chest compression, the airway opening, the artificial respiration and the compression-ventilation cycle. It should be noted that when the chest compression is performed, the pressing plate 8 moves downward relative to the initial position, and when the artificial respiration is performed, the pressing plate 8 moves upward relative to the initial position. Therefore, the displacement direction of the pressing plate 8 relative to the initial position is detected by one pull wire displacement sensor 7, and the chest compression and the artificial respiration action can be detected and distinguished. Specifically, the artificial respiration training can be performed by using a simple balloon resuscitator.

[0079] In the embodiment, the training item includes external defibrillation;

[0080] As shown, Figure 6 The defibrillator 4 is further connected with a pair of electrode pads 41, and is used for performing the defibrillation operation on the mannequin 1 in the external defibrillation item;

[0081] The rescue information acquisition module includes a defibrillation operation counter and an electrode pad positioner,

[0082] The defibrillation operation counter is used for counting the number of times of the defibrillation performed by the defibrillator 4;

[0083] The electrode pad positioner is used for detecting the position of the electrode pad 41 on the mannequin 1 during the defibrillation operation.

[0084] When the pulse is found to stop beating, the external defibrillation project should be judged to be executed. The defibrillation operation counter is arranged in the defibrillator 4, and the number of defibrillations is counted by detecting the number of times of pressing the switch of the defibrillator 4, so as to judge whether the number of defibrillations meets the standard. The electrode pad locator is arranged on the electrode pad 41, and the corresponding sensing element corresponding to the electrode pad locator is arranged at the corresponding position of the mannequin 1, so that the information is collected when the electrode pad 41 is attached to the correct position of the mannequin 1, so as to judge whether the position of the electrode pad 41 meets the standard.

[0085] In an embodiment, the electrode pad locator is a magnet, and a sheet-shaped Hall matrix sensor is arranged at the corresponding chest cavity part of the mannequin 1. When the electrode pad 41 is attached to the corresponding part of the chest cavity, the sheet-shaped Hall matrix sensor can read the coordinates of the magnet, so as to determine whether the electrode pad 41 is attached and whether it is attached to the correct position. Specifically, the polarities of the magnets on the two electrode pads 41 are arranged in opposite directions, so that the positions of the two electrode pads corresponding to different electrode polarities can be positioned respectively, and the situation that the two electrode pads 41 are attached in reverse is prevented.

[0086] In the embodiment, the trauma situation includes bleeding at the preset part of the corresponding limb, and the training project includes trauma bandaging.

[0087] The bandage is also included, which is used for bandaging the bleeding position of the corresponding limb of the mannequin 1 when the trauma bandaging project is performed, and the bandage has light transmittance.

[0088] The rescue information acquisition module includes a trauma bandaging pressure sensor arranged at the preset position of the limb of the mannequin 1, which is used for detecting the force of bandaging.

[0089] The rescue information acquisition module includes a bandaging layer number detector, which is a light-sensitive sensor 51 arranged at the preset position of the limb of the mannequin 1.

[0090] The trauma bandaging project includes a plurality of training projects corresponding to the bandaging method, and the bandaging method includes ring bandaging and spiral bandaging.

[0091] The rescue information acquisition module includes a bandaging method detector, which includes a bandaging layer number detector and / or a group of light-sensitive elements 52 arranged along the extension direction of the limb.

[0092] The bandaging layer number detector is a light-sensitive sensor 51 arranged at the preset position of the mannequin.

[0093] The group of light-sensitive elements 52 arranged along the extension direction of the limb is used for detecting the trajectory of the bandage wound at the limb of the mannequin, so as to judge the bandaging method executed. It should be noted that the light-sensitive element 52 can also execute the detection of the number of bandaging layers.

[0094] The tightness of the bandage is detected by the pressure sensor. The light transmittance of the bandage decreases with the increase of the number of layers of the bandage. The light sensor 51 is arranged at the bandaging position to detect whether the number of layers of the bandage at the bandaging position is qualified. When the spiral bandaging method is used, the bandage covers the light sensitive elements 52 arranged along the extension direction of the limb in sequence. Therefore, the change of the output signal of the light sensitive elements 52 can be used to detect the trajectory of the bandage to determine whether the spiral bandaging method is used.

[0095] Specifically, the detection process of the circular bandaging is as follows:

[0096] The number of times of change of the output parameter of the light sensor 51 or the light sensitive element 52 at the preset position and the trend of each change are detected.

[0097] If the output parameter of the light sensor 51 or the light sensitive element 52 at the preset position is detected to change, and the trend of each change corresponds to the decrease of the brightness, it is determined that the circular bandaging method is used. The image display plays the bandaging animation at the corresponding position to real-time feedback the bandaging effect. Otherwise, it is determined that the bandaging method is incorrect.

[0098] The number of times of change of the output parameter of the light sensor 51 or the light sensitive element 52 corresponds to the number of layers of the bandage, which is used to determine whether the number of layers of the bandage is qualified.

[0099] The detection process of the spiral bandaging is as follows:

[0100] The light sensitive elements 52 arranged along the extension direction of the limb are sequentially numbered.

[0101] The light intensity of the first light sensitive element 52 is detected to change within a preset range to determine the initial position of the bandage.

[0102] Subsequently, the light intensity of a pair of light sensitive elements 52 is detected to change within a preset range. It is determined whether the numbers corresponding to the two light sensitive elements 52 change in sequence. If the difference between the two numbers is 1, it is determined that the numbers change in sequence.

[0103] When the numbers are determined to change in sequence, it is determined that the spiral bandaging method is used. The image display plays the bandaging animation at the corresponding position to real-time feedback the bandaging effect. Otherwise, it is determined that the bandaging method is incorrect.

[0104] Specifically, during the training process of the wound bandaging, the light sensor 51 or the light sensitive element 52 that is not bandaged is used to input the signal of the intensity of the ambient light as a reference parameter to overcome the interference signal caused by the shadow, the switching of the light and other environment.

[0105] In the embodiment, the wound condition includes the fracture of the preset part of the limb, and the training project includes the fixation of the limb.

[0106] Also included is a fixator splint for fixing the fractured position of the corresponding limb of the mannequin 1 when performing the limb fixation project;

[0107] The rescue information acquisition module includes a splint positioning sensor for detecting the position of the fixator splint on the mannequin 1.

[0108] The splint positioning sensor can be a proximity switch and a sensor respectively arranged on the fixator splint and the fractured position of the limb.
