Abstract
Description
Technical Field
[0001] This invention relates to the field of high-altitude emergency medical equipment technology, specifically providing a field transport emergency bed and a high-altitude emergency vehicle. Background Technology
[0002] High altitudes are unique environments characterized by low air pressure, low oxygen, extreme cold, and high ultraviolet radiation. These conditions exert a series of unique stimuli on human physiological activities, with low oxygen levels having the most significant impact. In high-altitude environments, many physiological changes negatively affect overall physical capabilities to varying degrees. Activities that are normally performed at lower altitudes become more difficult at high altitudes.
[0003] Furthermore, the terrain and geological conditions in the wild are much harsher and more complex, making existing emergency beds difficult to use in the field, especially in high-altitude areas. Stretches, which are frequently used for emergency transport in the wild, require at least two people to lift them. This not only increases the number of personnel needed, but also poses a significant risk of injury to the person being rescued if even one person falls.
[0004] Therefore, there is an urgent need for a field transport and emergency bed that requires fewer personnel, saves labor, and is suitable for safe use in complex terrain environments. Summary of the Invention
[0005] The purpose of this invention is to provide a field transport emergency bed that is small in size when folded, easy to transport, and can be safely transferred by one transporter on wet and soft ground. It can also be easily transferred by one transporter to an ambulance.

[0058] The method for transferring 300 people awaiting rescue to a high-altitude ambulance using the field transport emergency bed 100 provided by this invention is described in the following reference: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 :
[0059] S1. Lift the front of the field transport emergency bed 100, pull the lifting component 110 to rotate counterclockwise by about 180 degrees, and then use the lifting hook 114 to lower the field transport emergency bed 100 to the front wheel 5 and place it on the ground.
[0060] S2. Place the head-forward longitudinal tube 124 of the person to be rescued on the support cloth 10, and secure the person to be rescued 300 with the protective belt 20.
[0061] S3. The transport personnel 400 hold the hook 114 and pull the field transport first aid bed 100 up until the front wheel 5 leaves the ground. Then the transport personnel 400 continue to pull the field transport first aid bed 100 toward the high-altitude ambulance.
[0062] S4. Upon reaching the rear of the high-altitude ambulance, hook the hook rod 114 onto the abutment 214 at the rear end of the high-altitude ambulance's cargo floor 210. Then, the transport personnel 400 walks to the rear end of the field transport emergency bed 100, lifts the rear longitudinal tube 123 by hand, and then uses the three-state switch (the three-state switch can be marked with "lift", "off", and "lower") to start the worm gear output head motor 9 to rotate, causing the front end of the bed frame 120 to rise along the lifting member 110. At the same time, the transport personnel 400 simultaneously lifts the rear end of the bed frame 120 to make the bed frame 120 basically parallel to the ground. When the front end of the bed frame 120 moves to the end, the three-state switch is turned to the off state.
[0063] S5, the transfer personnel 400 push the rear longitudinal tube 123 to the field transfer emergency bed 100 and completely move it onto the carriage floor 210.
[0064] When using the field transport first aid bed 100 of the present invention to transport the person to be rescued 300 on wet, slippery and soft ground, first flip the skateboard 70 under the rear wheel 40, and then transport them in the manner described above.
[0065] The principle of how the worm gear output head motor 9 drives the front end of the bed frame 120 to rise along the lifting member 110:
[0066] When the longitudinal tube 124 is located at the lower end of the lifting member 110, the rope 60 is only connected between the winding part 83 and the rope fixing hole 115, and is not wound on the winding part 83. When the worm output head motor 9 is started, the worm 91 rotates, driving the worm wheel 81 to rotate, and then the winch 8 rotates to wind the rope 60 on the winding part 83. As the rope 60 is wound on the winding part 83, the front end of the bed frame 120 is lifted to the upper end of the lifting member 110. After the bed frame 120 is lifted to the upper end of the lifting member 110, when the transfer personnel 400 push the rear longitudinal tube 123 forward, the lifting member 110 will rotate clockwise with the lower end of the hook rod 114 as the fulcrum. After the front wheel 5 lands on the carriage floor 210, the connecting rod 111 on the lifting member 110 rotates to the magnet near the bottom of the bed frame 120 and is attracted and fixed.
[0067] When it is necessary to move the front end of the bed frame 120 down to the lower end of the lifting member 110, first pull the lower end of the lifting member 110 away from the magnet, then rotate it counterclockwise until the lifting member 110 is basically perpendicular to the bed frame 120. Then, start the worm gear output motor 9 to rotate in the opposite direction until the front end of the bed frame 120 moves down to the lower end of the lifting member 110. After that, the lifting member 110 can be rotated clockwise and folded under the bed frame 120.
[0068] Of course, a mechanism for retracting a measuring tape can be provided at the rope fixing hole 115 to ensure that the rope 60 is always in a tightened state, further improving the convenience of moving the front end of the bed frame 120 down to the lower end of the lifting member 110.
[0069] The method provided by this invention for transferring a field transport first aid cot 100 carrying 300 people in need of rescue to the first aid station 211 inside an ambulance 200 with minimal effort is described in the following article. Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 10 :
[0070] S1. The field transport emergency bed 100 is moved to the point where the protrusion 2152 on the bed lifting component 215 can hook the rear side of the hook rod 6.
[0071] S2. Hold the end of the lifting rod 2153 and turn it clockwise onto the platform. At this time, the protruding column 2152 supports the back of the hook rod 6 and the bottom of the bed frame 120, lifting the upper part of the field transport emergency bed 100. Then continue to rotate the lifting rod 2153 until the locking rod 1242 under the front longitudinal tube 124 falls onto the emergency table 211.
[0072] S3. Hold the rear longitudinal tube 123 and lift the bed frame 120 until it is parallel to the top of the emergency table 211. Then push the rear longitudinal tube 123 forward until the locking rod 1242 is inserted into the slot 2111 on the emergency table 211. Finally, tighten the hand screw 2 on the side of the locking rod 1242 to fix the field transport emergency bed 100 on the emergency table 211.
[0073] The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
