Description

Technical Field

[0001] This invention relates to the field of medical rescue technology, specifically a temporary helipad for medical rescue. Background Technology

[0002] With the continuous development of the medical industry, the demand for medical devices has been further boosted. Among the current medical equipment, rescue helicopters are being used more and more widely. Rescue helicopters can further avoid traffic congestion and thus achieve timely treatment.

[0003] When an emergency occurs in the field, it is necessary to set up a temporary rescue station. Therefore, a helipad needs to be built at the temporary rescue station for the temporary parking of rescue helicopters. However, building a helipad near a temporary rescue station cannot guarantee that the ground at the parking location is flat enough. Moreover, building a temporary helipad wastes a lot of time and resources, which has a significant impact on medical rescue. Therefore, we propose a temporary helipad for medical rescue. Summary of the Invention

[0004] The purpose of this invention is to provide a temporary helipad for medical rescue, in order to solve the problems that need to be addressed in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a temporary helipad for medical rescue, comprising a first fixed base and a second fixed base, two sets of hinge seats fixedly installed on one side of the second fixed base, a hinge rod inserted into the hinge seat fixedly installed on the first fixed base, two sets of positioning mechanisms fixedly installed on the top of the first fixed base, a parking mechanism for parking rescue helicopters being connected inside the positioning mechanism, the parking mechanism always being in a horizontal state due to its own weight, a locking mechanism for locking the parking mechanism being provided on both the first and second fixed bases, and a stretcher transfer mechanism for transferring rescue helicopter stretchers fixedly installed on one side of the second fixed base, the stretcher transfer mechanism being provided with a stretcher fixing mechanism to prevent stretcher displacement.

[0006] In the event of an emergency in the field, temporary rescue stations need to be set up. Therefore, helipads are required at these temporary rescue stations for temporary parking of rescue helicopters. However, building helipads near temporary rescue stations often doesn't guarantee a sufficiently flat ground surface, and the construction of temporary helipads wastes a significant amount of time and resources, thus greatly impacting medical rescue efforts. This invention features a separate design for the first fixed base, second fixed base, and parking mechanism, facilitating easy transport and faster setup. The parking mechanism can rotate along a positioning mechanism, ensuring it remains horizontal due to its own weight. This allows for horizontal placement even on unstable surfaces, adapting to various ground conditions. After placement, a locking mechanism secures the bottom sides of the parking mechanism, preventing it from shifting and ensuring that the parking mechanism won't shift when the rescue helicopter is parked.

[0007] Preferably, the positioning mechanism includes a fixing bolt, a positioning plate, and a support base. The positioning plate is fixedly installed on the top of the second fixed base by the fixing bolt. One bottom side of the positioning plate overlaps the top of the first fixed base. The support base is fixedly installed on the top of the positioning plate. Multiple sets of first fixed seats are fixedly installed on the inner wall of the support base. First ball bearings are rotatably connected to the first fixed seats.

[0008] Preferably, the parking mechanism includes a fixed shaft and a parking plate, with fixed shafts fixedly installed on both sides of the parking plate, and the outer wall of the fixed shafts contacting multiple sets of the first ball bearings.

[0009] Preferably, the first fixed base and the second fixed base have the same structure and both include a first fixed frame, a connecting seat, a fixed ring and a support leg. Multiple sets of connecting seats are fixedly installed at the bottom of the first fixed frame, and multiple sets of support legs are fixedly installed on one side of the fixed ring and at the position corresponding to the connecting seats. The top of the support leg is inserted into the interior of the connecting seat.

[0010] Preferably, the locking mechanism includes a first fixed plate, a first threaded sleeve, a first turntable, and a first threaded rod. The first fixed plate is fixedly connected to the fixed ring. Multiple sets of first threaded sleeves are fixedly installed on the first fixed plate. The first threaded sleeves are internally threaded with a first threaded rod. The bottom of the first threaded rod is fixedly connected to the first turntable. The top of the first threaded rod contacts the bottom of the stop plate.

[0011] Preferably, the stretcher transfer mechanism includes a second fixed plate, a first limiting rod, a transfer frame, and a second threaded sleeve. The second fixed plate is fixedly installed on the other side of the fixed ring. Two sets of first limiting rods are slidably connected to the second fixed plate. The transfer frame is fixedly connected to the top of the first limiting rod. The second threaded sleeve is fixedly installed on the second fixed plate. The second threaded sleeve is internally threaded with a second threaded rod. The top of the second threaded rod is rotatably installed on the bottom of the transfer frame. The bottom of the second threaded rod is fixedly installed with a second turntable.

[0012] Preferably, the stretcher fixing mechanism includes a snap-fit ​​plate, a clearance groove, a pressure plate, and a third fixing plate. The snap-fit ​​plate is slidably connected inside the transfer frame. A clearance groove is provided on one side of the transfer frame. The third fixing plate is fixedly installed at the bottom of the transfer frame. Two sets of second limiting rods are slidably connected to the third fixing plate. The top of the second limiting rods is fixedly connected to the bottom of the snap-fit ​​plate. A spring is fixedly connected to the top of the third fixing plate and to the outer surface of the second limiting rods. The top of the spring is fixedly installed at the bottom of the transfer frame.

[0013] Preferably, the transfer frame has multiple sets of second fixed seats fixedly installed inside, the top of the second fixed seats is rotatably connected to a second ball bearing, the outer surfaces of the first fixed base and the second fixed base are fixedly installed with multiple sets of handles, and the bottom of the connecting seat is fixedly connected to a frustum-shaped extension ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The first fixed base, the second fixed base and the parking mechanism of the present invention are designed as separate units, which facilitates their transportation and makes the assembly process faster and more convenient. The parking mechanism can rotate along the positioning mechanism, so that the parking mechanism can always be in a horizontal state due to its own weight. This ensures that the parking mechanism can be placed horizontally even on unstable ground, thus adapting to different ground environments.

[0016] 2. After the parking mechanism is placed, the bottom two sides of the parking mechanism are fixed by the locking mechanism. This will prevent the parking mechanism, which is in a horizontal position, from shifting again. After it is fixed, the parking mechanism will not shift when the rescue helicopter is parked.

[0017] 3. The stretcher transfer mechanism allows for the rapid transfer of patients using stretchers from the parking facility, facilitating the transfer of rescue stretchers by rescue station staff. After the stretcher is transferred to the top of the stretcher transfer mechanism, it can be secured using the stretcher fixing mechanism to prevent the stretcher from swaying or shifting during transport.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-3 This invention provides a technical solution: a temporary helipad for medical rescue, comprising a first fixed base 1 and a second fixed base 2. Two sets of hinge seats 3 are fixedly installed on one side of the second fixed base 2. A hinge rod 4 inserted into the hinge seat 3 is fixedly installed on the first fixed base 1. Two sets of positioning mechanisms 5 are fixedly installed on the top of the first fixed base 1. A parking mechanism 6 for parking rescue helicopters is connected inside the positioning mechanism 5. The parking mechanism 6 is always in a horizontal state due to its own weight. Both the first fixed base 1 and the second fixed base 2 are provided with locking mechanisms 7 for locking the parking mechanism 6. A stretcher transfer mechanism 8 for transferring rescue helicopter stretchers is fixedly installed on one side of the second fixed base 2. The stretcher transfer mechanism 8 is provided with a stretcher fixing mechanism 9 to prevent stretcher displacement.

[0024] The first fixed base 1, the second fixed base 2, and the parking mechanism 6 are designed as separate units, facilitating their transport. During assembly, the hinge rod 4 on the first fixed base 1 is simply inserted into the hinge seat 3 of the second fixed base 2. This installation method is quick and convenient. The parking mechanism 6 can rotate along the positioning mechanism 5, ensuring it remains horizontal due to its own weight. This design allows the parking mechanism 6 to remain horizontal even on unstable surfaces, adapting to various ground conditions. After completion, the bottom sides of the parking mechanism 6 are fixed using the locking mechanism 7. This prevents the parking mechanism 6, which is in a horizontal position, from shifting again. It also ensures that the parking mechanism 6 will not shift when the rescue helicopter is parked after the fixation is completed. The stretcher transfer mechanism 8 facilitates the rapid transfer of patients using stretchers from the parking mechanism 6, making it convenient for rescue station staff to transfer the rescue stretchers. After the stretcher is transferred to the stretcher transfer mechanism 8, the stretcher fixing mechanism 9 can be used to fix the stretcher, thereby preventing the stretcher from shaking or shifting during the transfer process.

[0025] Please see Figure 1 and Figure 2 The first fixed base 1 and the second fixed base 2 have the same structure and both include a first fixed frame 15, a connecting seat 16, a fixed ring 17 and a support leg 18. Multiple sets of connecting seats 16 are fixedly installed at the bottom of the first fixed frame 15. Multiple sets of support legs 18 are fixedly installed on one side of the fixed ring 17 and at the position corresponding to the connecting seat 16. The top of the support leg 18 is inserted into the interior of the connecting seat 16. Multiple sets of handles 40 are fixedly installed on the outer surface of the first fixed base 1 and the second fixed base 2. A frustum-shaped extension ring 19 is fixedly connected to the bottom of the connecting seat 16.

[0026] During the installation of the first fixed base 1 and the second fixed base 2, multiple sets of support legs 18 are first inserted into the interior of multiple sets of fixing rings 17. The frustum-shaped extension ring 19 makes it easier to insert the support legs 18 into the interior of the fixing rings 17. Then, the hinge rod 4 on the first fixed base 1 is inserted into the hinge seat 3 of the second fixed base 2 to complete the fixed installation of the first fixed base 1 and the second fixed base 2.

[0027] Please see Figure 1 , Figure 2 and Figure 3The positioning mechanism 5 includes a fixing bolt 10, a positioning plate 11, and a support base 12. The top of the second fixed base 2 is fixedly mounted with the positioning plate 11 by the fixing bolt 10. One bottom side of the positioning plate 11 overlaps the top of the first fixed base 1. The top of the positioning plate 11 is fixedly mounted with the support base 12. Multiple sets of first fixed seats 13 are fixedly mounted on the inner wall of the support base 12. First ball bearings 14 are rotatably connected to the first fixed seats 13. The parking mechanism 6 includes a fixing shaft 20 and a parking plate 21. The fixing shaft 20 is fixedly mounted on both sides of the parking plate 21. The outer wall of the fixing shaft 20 contacts the multiple sets of first ball bearings 14.

[0028] In the process of placing the parking mechanism 6, the fixed shafts 20 on both sides of the parking plate 21 are first placed into the support base 12, so that the first ball bearing 14 contacts the fixed shaft 20. This arrangement makes it easy for the parking plate 21 and the fixed shaft 20 to rotate automatically along the first ball bearing 14. This arrangement also makes it easy for the parking plate 21 to be in a horizontal state by its own weight.

[0029] Please see Figure 1 and Figure 2 The locking mechanism 7 includes a first fixing plate 22, a first threaded sleeve 23, a first turntable 24, and a first threaded rod 25. The first fixing plate 22 is fixedly connected to the fixing ring 17. Multiple sets of first threaded sleeves 23 are fixedly installed on the first fixing plate 22. The first threaded sleeve 23 is internally threaded with a first threaded rod 25. The bottom of the first threaded rod 25 is fixedly connected to the first turntable 24. The top of the first threaded rod 25 contacts the bottom of the stop plate 21.

[0030] Once the stop plate 21 is in place, the first turntable 24 is rotated, causing the first threaded rod 25 to rotate along the inside of the first threaded sleeve 23. This allows the top of the first threaded rod 25 to contact the bottom of the stop plate 21, thus preventing the stop plate 21 from shifting back and forth after it has reached a horizontal position.

[0031] Please see Figure 1 and Figure 2The stretcher fixing mechanism 9 includes a snap-fit ​​plate 34, a clearance groove 35, a pressure plate 36, and a third fixing plate 37. The snap-fit ​​plate 34 is slidably connected inside the transfer frame 28. The pressure plate 36 is fixedly connected to one side of the snap-fit ​​plate 34. The clearance groove 35 is opened on one side of the transfer frame 28. The third fixing plate 37 is fixedly installed at the bottom of the transfer frame 28. Two sets of second limiting rods 38 are slidably connected on the third fixing plate 37. The top of the second limiting rods 38 is fixedly connected to the bottom of the snap-fit ​​plate 34. A spring 39 is fixedly connected to the top of the third fixing plate 37 and located on the outer surface of the second limiting rods 38. The top of the spring 39 is fixedly installed at the bottom of the transfer frame 28. Multiple sets of second fixing seats 33 are fixedly installed inside the transfer frame 28. The top of the second fixing seat 33 is rotatably connected to a second ball bearing 32.

[0032] After the rescue helicopter is parked, press the pressure plate 36 to lower the locking plate 34 and make way for the stretcher. Then place the stretcher above the second ball bearing 32. The second ball bearing 32 can then easily push the stretcher above the transfer frame 28. Then release the pressure plate 36. Because of the action of the spring 39, the locking plate 34 can move back up and lock the stretcher in place.

[0033] Please see Figure 1 and Figure 2 The stretcher transfer mechanism 8 includes a second fixed plate 26, a first limiting rod 27, a transfer frame 28, and a second threaded sleeve 29. The second fixed plate 26 is fixedly installed on the other side of the fixed ring 17. Two sets of first limiting rods 27 are slidably connected to the second fixed plate 26. The transfer frame 28 is fixedly connected to the top of the first limiting rods 27. The second threaded sleeve 29 is fixedly installed on the second fixed plate 26. The second threaded sleeve 29 is internally threaded with a second threaded rod 30. The top of the second threaded rod 30 is rotatably installed on the bottom of the transfer frame 28. The bottom of the second threaded rod 30 is fixedly installed with a second turntable 31.

[0034] Once the stretcher is secured, the second turntable 31 is rotated, causing the second threaded rod 30 to rotate along the second threaded sleeve 29. This allows the transfer frame 28 to descend continuously, facilitating timely transfer of the stretcher and the injured by medical personnel at the rescue station.

[0035] In use, the first fixed base 1, the second fixed base 2, and the parking mechanism 6 are designed as separate units for easy transport. During assembly, the hinge rod 4 on the first fixed base 1 is inserted into the hinge seat 3 of the second fixed base 2. This installation method is quick and convenient. The parking mechanism 6 can rotate along the positioning mechanism 5, ensuring it remains horizontal due to its own weight. This design allows the parking mechanism 6 to remain horizontal even on unstable surfaces, adapting to various ground conditions. After the parking mechanism 6 is in place, the locking mechanism 7 secures the bottom sides of the parking mechanism 6 to prevent it from becoming horizontal. The parking mechanism 6 in its current state shifts again, and after it is secured, the parking mechanism 6 will not shift when the rescue helicopter is parked. The stretcher transfer mechanism 8 facilitates the rapid transfer of patients using stretchers from the parking mechanism 6, making it convenient for rescue station staff to transfer the rescue stretchers. After the stretcher is transferred to the stretcher transfer mechanism 8, the stretcher fixing mechanism 9 can be used to fix the stretcher, thereby preventing the stretcher from shaking or shifting during the transfer. When installing the first fixing base 1 and the second fixing base 2, multiple sets of support legs 18 are first inserted into the interior of multiple sets of fixing rings 17. The frustum-shaped extension ring 19 makes it easier for the support legs 18 to be inserted into the fixing ring 17. The hinge rod 4 on the first fixed base 1 is inserted into the hinge seat 3 of the second fixed base 2 to complete the fixed installation of the first fixed base 1 and the second fixed base 2. When placing the parking mechanism 6, firstly, the fixed shafts 20 on both sides of the parking plate 21 are placed into the support base 12, so that the first ball bearing 14 contacts the fixed shaft 20. This arrangement facilitates the automatic rotation of the parking plate 21 and the fixed shaft 20 along the first ball bearing 14. This arrangement allows the parking plate 21 to easily maintain a horizontal position using its own weight. After the parking plate 21 is placed, the first turntable 24 is rotated. The first turntable 24 drives the first threaded rod 25 to rotate along the inside of the first threaded sleeve 23, and then the top of the first threaded rod 25 can be aligned with the parking mechanism 6. The bottom of the landing plate 21 is in contact, which prevents the landing plate 21 from shifting back and forth after it is in a horizontal position. After the rescue helicopter is parked, press the pressure plate 36 to move the locking plate 34 down and make way for the stretcher. Then place the stretcher above the second ball bearing 32. The second ball bearing 32 can then push the stretcher up to the transfer frame 28. Then release the pressure plate 36. The spring 39 can make the locking plate 34 move up again and lock the stretcher in place. After the stretcher is fixed, rotate the second turntable 31 to make the second threaded rod 30 rotate along the second threaded sleeve 29. This allows the transfer frame 28 to continue to descend, which makes it easier for medical personnel at the rescue site to transfer the stretcher and the wounded in a timely manner.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
