Description

Technical Field

[0001] This invention belongs to the technical field of equipment for training first aid skills by military medical personnel, specifically relating to a training device for simulating bumpy and shaking conditions in field. Background Technology

[0002] For every medical worker in the military, providing timely first aid to the wounded in harsh field conditions is an essential skill. However, in peacetime, there are no real-life scenarios for medical workers to train in, and they can only acquire some knowledge from theoretical books. The actual application in wartime environments may be quite different. Therefore, simulation training devices are needed to improve the first aid skills of medical workers. Existing simulated first aid training usually only simulates shaking conditions. However, in the field, the rescue scenarios are complex and varied, and traditional simulated first aid training devices are difficult to simulate, such as sharp turns, continuous turns and bumpy conditions. This limits the training scope for medical personnel and makes it difficult to further improve their rescue skills.

The movable block 221 is slidably connected to the surface of the constraint rod 220 through a small hole. The two ends of the two springs 222 are fixedly connected to the rectangular block 218 and the movable block 221 respectively. Telescopic rods 231 are fixedly connected to the surface of the guide plate 227 near the four corners. Universal joints 232 are installed at the ends of the telescopic rods 231 and the ends of the universal joints 232 are installed on the bottom surface of the bearing plate 229.

[0019] It should be noted that this device can be used in conjunction with a controller, which can control the moving speed of the mobile vehicle 207, the rotation speed of drive motor 206, and the rotation speed of drive motor 216, thereby adjusting the training intensity and training pattern of this device. During the movement of the mobile vehicle 207, the second guide wheel 211 can be moved from the fourth constraint groove 235 to the inside of the fifth constraint groove, and the first guide wheel 208 can be moved from the fifth constraint groove to the inside of the fourth constraint groove 235, which facilitates the adjustment of the movement trajectory of the mobile vehicle 207.

[0020] Working principle and workflow: During field simulation training, medical personnel first enter the ambulance body 233 to prepare for rescue operations on the training dummy inside. Simultaneously, the moving vehicle 207 is activated and moves within track 201. During the movement of the moving vehicle 207, guide wheels 211 and 208 are located within constraint grooves 235 and 235 respectively. With the cooperation of T-shaped rod 209 and spring 210, the rigidity of the moving vehicle 207 is reduced as it moves within track 201. The damage caused by the collision is mitigated by controlling the operation of the drive motor 206, which causes the cavity 204 to move the arc-shaped adjustment rail 203 inside the slide groove 202 via the toothed groove 234. This causes the end of the arc-shaped adjustment rail 203 to extend and contact the training base 101, thereby causing the moving vehicle 207 to change track along the part of the arc-shaped adjustment rail 203 that extends out of the slide groove 202 when the track 201 moves. This allows the moving vehicle 207 to make circular motion on one side of the training base 101 or move along the trajectory of the number 8 on the surface of the training base 101. In this embodiment, during the movement of the moving vehicle 207, the second drive motor 216 is activated, causing the first lead screw 215 to rotate. The rotation of the first lead screw 215 causes the first moving block 214 to reciprocate along the surface of the first constraint rod 213 inside the constraint frame 212. Under the coordination of the second constraint rod 220 and the second spring 222 inside the rectangular block 218, and the constraint of the S-shaped guide groove 228 on the guide plate 227, the connecting rod 224 on the second moving block 221 drives the ball 226 inside the ball seat 225 to move along the bottom surface of the bearing plate 229 and the surface of the semi-cylindrical block 230, thereby... The ambulance body 233 undulates, and during the movement of the moving block 214, the rotation of the cam 223, in conjunction with the constraint groove 219 and the T-shaped rod 217, causes the rectangular block 218 to continuously reciprocate in the vertical direction. This makes the pushing motion of the ball 226 on the support plate 229 more complex, delaying the adaptation of medical personnel to the regular shaking during training, thereby enabling the device to achieve a better training effect. During the undulation of the S-shaped guide groove 228, the extension and retraction of the telescopic rod 231 and the adjustment of the universal joint 232 ensure that the support plate 229 maintains the stability of its connection with the device during the shaking process.

[0021] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
