A set of pull arm supports 22 are provided on both sides of the main frame 1 of the device. The pull arm supports 22 are hinged with the pull arm 24 through a torsion spring shaft 23. One end of the pull arm 24 is connected to the The pull plate 21 is matched, the other end of the pull arm 24 is connected to the pull arm slide button 15 through a pull arm pull cord 25, and a set of sloped surface blocking blocks 26 are provided on the side of the mounting frame 5, the sloped surface blocking blocks 26 is matched with the mounting frame 5 through a return spring 27, the slope block 26 is connected to the block slide button 14 by a block pull cord 28, and the handle 13 is provided with a pull arm slide groove 30 and a card Block sliding groove 31, the pull arm sliding button 15 is slidingly fitted with the pulling arm sliding groove 30, the clamping block sliding button 14 is slidingly fitted with the clamping block sliding groove 31, the pull arm pull cord 25 and the The clip pull cords 28 are all arranged in the device main frame 1 and cooperate with the rollers 29 arranged in the device main frame 1. A set of shock-absorbing plates 32 are arranged at the lower part of the mounting frame 5, and the shock-absorbing plates 32 A shock-absorbing spring 33 is provided on one side, and the shock-absorbing spring 33 is adapted to the rotating square sleeve 7, and the rotating square sleeve 7 is provided with a mounting groove 34 inside, and the supporting spring 8 is arranged in the mounting groove 34 Inside, a block groove 35 is opened on one side of the rotating square sleeve 7, and the block groove 35 is adapted to the slope block 26.

[0025] Working principle: When using the spine surgery stretcher, two medical staff cooperate, each holding the handle 13 at one end of the device main frame 1 lifts the device to move, moves the device main frame 1 to the vicinity of the patient, and then uses the inflator 12 pairs of air cushions 11 are inflated. After the air cushion 11 is inflated, the medical staff move the patient to the air cushion 11 on the main frame 1 of the device. The air cushion 11 can increase the patient’s comfort when lying down, and at the same time can reduce The main frame 1 of the device is a rigid plate-like structure, which can provide good support. The patient lies on the main frame 1 of the device, and the main frame 1 of the device is not deformed, which avoids the floating deformation of the traditional cloth stretcher. This causes the patient’s torso to be difficult to fix. The rotating square sleeve 7 is placed horizontally at the beginning, and the rotating square sleeve 7 is attached to the side of the mounting frame 5. After the patient lies down, the medical staff can grasp the handle 13 to hold the device The frame 1 is lifted to move the patient. When moving to an ambulance or other rescue place, it can be directly lifted to the destination. When the distance is far, the medical staff can use the index finger to pull the block on the handle 13 The slide button 14, the clip slide button 14 is pulled back in the clip slide groove 31, and then the clip pull cord 28 connected with the clip slide button 13 is pulled, and the other end of the clip pull cord 28 is locked with the slope surface. If the block 26 is connected, the ramp block 26 is pulled into the mounting frame 5, and the block groove 35 on the rotating square sleeve 7 is matched with the ramp block 26, and the ramp block 26 is pulled back to the mounting frame 5. After being inside, the block groove 35 loses the limiting function of the slope block 26. At this time, the rotating square sleeve 7 will rotate and fall under the action of gravity. When falling, the rotating square sleeve 7 will be affected by the elastic force of the damping spring 33 It is buffered to prevent the angle of the rotating square sleeve 7 from being too large and hurting the legs of the medical staff. After the medical staff releases the block sliding button 14, the slope block 26 will reset under the elastic force of the return spring 27, and the square sleeve can be rotated. 7 After being stabilized, the medical staff can pull the arm slide button 15 with the thumb. The arm slide button 15 is connected to the arm rope 25. The arm slide button 15 drives the arm rope 25 so that the arm rope 25 overcomes the torsion spring axis. The rebound force of 23 pulls down one end of the pull arm 24, and the other end of the pull arm 24 is tilted. At this time, the pull plate 21 loses the pulling action of the pull arm 24, and the side frame 3 falls under the action of gravity, and the limit plate 4 and The position of the rotating square sleeve 7 is adapted after it hangs down. After falling, the limit plate 4 is matched with the rotating square sleeve 7. The magnetic plate 20 and the side of the rotating square sleeve 7 are adsorbed to complete the fixing of the side frame 3, and then the rotating square sleeve 7 Can not swing under the limit effect of the limit plate 4, the whole device can contact the ground by rotating the square sleeve 7 and the support of the legs 9. The roller 29 can be set in the device main frame 1, and the roller 29 can reduce the jam The frictional force of the block rope 28 and the arm rope 25 prevents the block rope 28 and the arm rope 25 from directly rubbing against the corners of the main frame 1 of the device. The number of rollers 29 can be installed according to the actual situation. The position is enough to reduce friction. The use of universal wheel 10 makes the movement of the device convenient and labor-saving. Medical staff only need to pull the handle 13 to make the device move, which greatly reduces physical consumption. The time support spring 8 can play a shock-absorbing effect to prevent the patient from being strongly impacted when the main frame 1 of the device is bumped due to uneven road. At the same time, when the medical staff lifts the handle 13 to make the device pass through the road with bad road conditions, The direction wheel 10 is still in contact with the ground, and the support spring 8 can provide a certain lifting force, which reduces the weight of the medical staff.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
