Description

Technical Field

[0001] This invention relates to the field of rescue stretcher technology, specifically a multifunctional, highly stable, intelligent emergency rescue stretcher. Background Technology

[0002] A rescue stretcher is a medical transport tool designed specifically for patients with limited mobility or injuries. It is usually made of high-strength materials and features portability, stability, and safety. It is an indispensable piece of equipment in medical emergency and rescue operations and is widely used in various emergency situations. The main purpose of a rescue stretcher is to help medical personnel quickly and effectively transport patients from one place to another. It is suitable for various emergency medical rescue scenarios.

[0003] Currently used rescue stretchers are generally moved on the road by rollers. However, the road surface is prone to damage at some accident sites, and the rescue stretcher may get stuck when moving on damaged surfaces. Rescuers need to manually retract the outriggers of the rescue stretcher, which takes a certain amount of time and wastes valuable rescue time. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional, highly stable, intelligent emergency rescue stretcher to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a multifunctional, highly stable, intelligent emergency rescue stretcher, comprising a stretcher with a reinforcing plate fixedly connected to its surface. A handle is fixedly connected to the end of the reinforcing plate. A groove is formed at the end of the stretcher, and a carrying strap is fixedly connected to the inner wall of the groove. A positioning groove is formed at the top of the stretcher, and an intelligent life monitoring device is installed at the bottom of the inner wall of the positioning groove. This intelligent life monitoring device can monitor the patient's vital signs in real time, such as heart rate, blood pressure, blood oxygen saturation, and body temperature, and synchronously transmit the data to the mobile terminal of medical personnel and the rear medical command center via a communication integration module. A sliding groove is formed at the end of the reinforcing plate away from the stretcher, and a circular groove is formed at the bottom of the stretcher. A communication integration module is fixedly connected to the bottom of the stretcher, facilitating medical personnel to quickly obtain the patient's vital sign information on-site. The invention also includes:

[0007] A support component, the support component including an electric actuator, the top of the electric actuator being fixedly connected to the top of the inner wall of the circular groove, the bottom of the electric actuator being fixedly connected to an extrusion plate, and the end of the extrusion plate being hinged to a circular hole frame;

[0010] Furthermore, two reinforcing plates are provided, symmetrically arranged around the stretcher, with the ends of the reinforcing plates extending to the outer ends of the stretcher. The circular groove is located at the bottom center of the stretcher. A semi-circular frame is fixedly connected to the top of each reinforcing plate, and a corrugated protective cover is fixedly connected to the surface of the semi-circular frame. A magnetic ring is fixedly connected to the end of the corrugated protective cover away from the semi-circular frame. Two semi-circular frames are provided, symmetrically arranged around the reinforcing plates, and two magnetic rings are provided. The ends of the two magnetic rings away from the corrugated protective cover are magnetically connected. When the two corrugated protective covers are attracted together by the magnetic rings, they can protect the patient. The corrugated protective cover has the effects of radiation protection, magnetic protection, bulletproof protection, and wind and rain protection, improving the protection effect for the patient.

[0011] Furthermore, the support component includes a mounting frame, the top of which is fixedly connected to the bottom of the stretcher, a rotating rod rotatably connected to the inner wall of the mounting frame, an elastic frame fixedly connected to the surface of the rotating rod, and a caster wheel rotatably connected to the end of the elastic frame;

[0012] A connecting frame is fixedly connected to the surface of the rotating rod, an arc-shaped sliding plate is fixedly connected to the bottom of the connecting frame, and a cylindrical frame is fixedly connected to the surface of the rotating rod.

[0013] Furthermore, the number of elastic frames is set to four, and the four elastic frames are set to two groups, with two in each group. The two groups of elastic frames are symmetrically arranged with the extrusion plate as the center.

[0014] Furthermore, the arc-shaped sliding plate is located below the mounting frame, the inner wall of the circular hole frame slides against the surface of the cylindrical frame, and there are two mounting frames, which are symmetrically arranged with the stretcher as the center.

[0015] Furthermore, the docking component includes a protruding plate, a semi-circular groove block is inserted into the surface of the protruding plate, a pressure groove is formed on the inner wall of the semi-circular groove block, a pressure plate is fixedly connected to the surface of the protruding plate, and sliders are fixedly connected to the surface of the protruding plate and the surface of the semi-circular groove block, respectively. The surface of the slider is fixedly connected to the end of the spring, and a limit groove is formed at the ends of the protruding plate and the pressure plate that are far apart from each other.

[0016] The inner wall of the limiting groove is rotatably connected to a roller, the bottom of the extrusion plate is fixedly connected to a connecting plate, and the end of the connecting plate is fixedly connected to an expansion frame.

[0017] Furthermore, the surface of the slider is slidably connected to the inner wall of the groove, the surface of the pressure plate is inserted into the inner wall of the pressure groove, the surface of the roller extends to the outer end of the limiting groove, the surface of the roller contacts the inner wall of the expansion frame, and the ends of the expansion frame are set far apart from each other.

[0018] Furthermore, the limiting component includes a second arc plate, the bottom of which is hinged to the top of the reinforcing plate, a grooved rod is fixedly connected to the end of the first arc plate away from the reinforcing plate, and a cylindrical rod is fixedly connected to the end of the second arc plate away from the reinforcing plate.

[0019] The cylindrical rod has a slot at one end away from the arc plate, and a socket plate is fixedly connected to the inner wall of the cylindrical rod. A magnetic plate is inserted into the inner wall of the cylindrical rod.

[0020] Furthermore, the surface of the cylindrical rod contacts the inner wall of the grooved rod, the surface of the insertion plate contacts the inner wall of the slot, the magnetic plate penetrates the grooved rod and extends into the interior of the grooved rod, and the lower surface of the magnetic plate contacts the inner wall of the insertion plate.

[0021] The present invention has the following beneficial effects:

[0022] When a stretcher needs to be moved, rescuers lift it using a lever for transport. When the stretcher needs to be moved on the road, an electric actuator is activated to move it downwards. This downward movement of the actuator pushes a perforated frame downwards via a compression plate. The perforated frame rotates downwards on the surface of a cylindrical frame, which in turn rotates a flexible frame downwards via a rotating rod. Once the bottom of the cylindrical frame is lowered, the flexible frame causes the casters to contact the road surface, allowing the stretcher to be moved. The flexible frame provides support for the stretcher, and when the casters traverse uneven surfaces, the elasticity of the frame reduces vibrations to the stretcher. The electric push rod can be moved upwards to retract the elastic frame into the bottom of the stretcher when encountering damaged road surfaces, improving the convenience of retraction and allowing rescuers to quickly transport the stretcher to the patient. When the casters are in contact with the ground, the curved sliding plate will move to the end of the stretcher as the lever rotates. After the elastic frame is retracted into the bottom of the stretcher, the curved sliding plate will rotate to the bottom of the mounting frame. When the stretcher is on snow or gravel surfaces, rescuers can pull the stretcher with the straps, and the stretcher will slide on the curved sliding plate, improving the practicality of the stretcher.

[0023] When a stretcher needs to be quickly locked and connected to a transport vehicle such as a helicopter, the elastic frame needs to be retracted to the bottom of the stretcher. At this time, the compression plate will move upward. When the compression plate moves upward, it pushes the expansion frame upward through the linkage plate. When the expansion frame moves upward, it will move with the surface of the roller. As the expansion frame moves, the roller pushes the protruding plate and the semi-circular groove block to move closer to each other. At this time, the fixing rope of the transport vehicle is placed into the movement of the protruding plate and the semi-circular groove block. When the protruding plate and the semi-circular groove block come into contact, they will compress and fix the fixing rope, thereby fixing the stretcher to the fixing rope of the transport vehicle. A pressure plate is provided on the surface of the protruding plate. When the pressure plate moves into the pressure groove, it will compress and bend the fixing rope, thereby increasing the friction between the fixing rope and the semi-circular groove block and improving the stability of the stretcher. By retracting the elastic frame, the stretcher is fixed to the rope of the transport vehicle, improving the convenience of docking the stretcher with the transport vehicle.

[0024] In this invention, after the patient lies on top of the stretcher, the first and second arc-shaped plates are pushed to move closer together. This movement pushes the grooved rod into the surface of the cylindrical rod, and the inner wall of the slot contacts the surface of the insertion plate. At this point, a magnetic plate is inserted into the insertion plate to fix the grooved rod and the cylindrical rod. The patient is thus secured to the top of the stretcher using the first and second arc-shaped plates, preventing the patient from falling off during transport. The contact between the patient's armpits and the surfaces of the first and second arc-shaped plates prevents the patient from sliding on the stretcher surface. When the patient applies pressure to the first and second arc-shaped plates, an outward expanding force is generated. Simultaneously, the cylindrical rod presses against the magnetic plate, and the grooved rod presses against the magnetic plate through the insertion plate. Under this force, the magnetic plate is locked inside the grooved rod, improving the stability of the connection between the first and second arc-shaped plates.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0040] 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.

[0041] Please see Figures 1-11 As shown, this invention is a multifunctional, highly stable, intelligent emergency rescue stretcher, including a stretcher 1. A reinforcing plate 2 is fixedly connected to the surface of the stretcher 1, and a handle 3 is fixedly connected to the end of the reinforcing plate 2. A groove 9 is formed at the end of the stretcher 1, and a carrying strap 10 is fixedly connected to the inner wall of the groove 9. A positioning groove is formed at the top of the stretcher 1, and an intelligent life monitoring device 8 is provided at the bottom of the inner wall of the positioning groove. A sliding groove 7 is formed at the end of the reinforcing plate 2 away from the stretcher 1. A circular groove 11 is formed at the bottom of the stretcher 1, and a communication integration module 12 is fixedly connected to the bottom of the stretcher 1. The invention also includes:

[0042] Support component 4 includes an electric push rod 21. The top of the electric push rod 21 is fixedly connected to the top of the inner wall of the circular groove 11, and the bottom of the electric push rod 21 is fixedly connected to an extrusion plate 22. The end of the extrusion plate 22 is hinged to a circular hole frame 27.

[0043] The docking component 5 includes a positioning plate 32, the end of which is fixedly connected to the inner wall of the slide groove 7, and a spring 33 is fixedly connected to the surface of the positioning plate 32.

[0044] The limiting component 6 includes an arc plate 50, the bottom of which is hinged to the top of the reinforcing plate 2.

[0045] There are two reinforcing plates 2, symmetrically arranged around the stretcher 1. The ends of the reinforcing plates 2 extend to the outer ends of the stretcher 1. The circular groove 11 is located at the bottom center of the stretcher 1. A semi-circular frame 13 is fixedly connected to the top of the reinforcing plate 2. A corrugated protective cover 14 is fixedly connected to the surface of the semi-circular frame 13. A magnetic ring 15 is fixedly connected to the end of the corrugated protective cover 14 away from the semi-circular frame 13. There are two semi-circular frames 13, symmetrically arranged around the reinforcing plate 2. There are two magnetic rings 15. Two magnetic rings 15 are magnetically connected at the ends away from the corrugated protective cover 14. The bottom of the magnetic rings 15 is slidably connected to the top of the reinforcing plate 2. When the corrugated protective cover 14 is needed to protect the patient, the magnetic rings 15 are pulled and slid on the surface of the reinforcing plate 2. After the two magnetic rings 15 come into contact with each other, they can be magnetically attracted together to fix the corrugated protective cover 14, thereby protecting the patient with the corrugated protective cover 14. When not in use, the corrugated protective cover 14 can be folded together for easy unfolding next time.

[0046] The support component 4 includes a mounting frame 20, the top of which is fixedly connected to the bottom of the stretcher 1. A rotating rod 23 is rotatably connected to the inner wall of the mounting frame 20. An elastic frame 29 is fixedly connected to the surface of the rotating rod 23. A caster wheel 28 is rotatably connected to the end of the elastic frame 29.

[0047] A connecting frame 25 is fixedly connected to the surface of the rotating rod 23. When the present invention needs to move the stretcher 1, the rescuer lifts the stretcher 1 by gripping the rod 3 and moves it. When the stretcher 1 needs to be moved on the road, the electric push rod 21 is activated to move downward. When the electric push rod 21 moves downward, it pushes the circular hole frame 27 downward through the extrusion plate 22. When the circular hole frame 27 moves downward, it rotates downward on the surface of the cylindrical frame 24. When the cylindrical frame 24 rotates downward, it drives the elastic frame 29 to rotate downward through the rotating rod 23. An arc-shaped sliding plate 26 is fixedly connected to the bottom of the connecting frame 25, and a cylindrical frame 24 is fixedly connected to the surface of the rotating rod 23.

[0048] There are four elastic frames 29. When the bottom of the cylindrical frame 24 hangs down, the elastic frame 29 will drive the casters 28 to contact the ground. At this time, the stretcher 1 can be moved on the ground. The elastic frame 29 supports the stretcher 1. When the casters 28 pass over some uneven ground, the elastic frame 29 uses its elasticity to reduce the vibration force on the stretcher 1 and reduce secondary injury to the injured person caused by bumps. The four elastic frames 29 are set in two groups, and each group has two. The two groups of elastic frames 29 are symmetrically arranged with the compression plate 22 as the center.

[0049] The curved sliding plate 26 is located below the mounting frame 20. The electric push rod 21 can be moved upward to store the elastic frame 29 at the bottom of the stretcher 1, which improves the convenience of storing the elastic frame 29 so that rescuers can quickly transport the stretcher to the patient. The inner wall of the round hole frame 27 slides against the surface of the cylindrical frame 24. There are two mounting frames 20, which are symmetrically arranged with the stretcher 1 as the center.

[0050] The docking component 5 includes a protruding plate 35, a semi-circular groove block 34 inserted into the surface of the protruding plate 35, and a pressure groove 36 formed on the inner wall of the semi-circular groove block 34. When it is necessary to quickly lock and connect the stretcher 1 to a transport vehicle such as a helicopter, the elastic frame 29 needs to be stored at the bottom of the stretcher 1. At this time, the compression plate 22 will move upward. When the compression plate 22 moves upward, it pushes the expansion frame 38 upward through the linkage plate 31. When the expansion frame 38 moves upward, it will move with the surface of the roller 39. A pressure plate 37 is fixedly connected to the surface of the protruding plate 35. A slider 30 is fixedly connected to the surface of the protruding plate 35 and the surface of the semi-circular groove block 34, respectively. The surface of the slider 30 is fixedly connected to the end of the spring 33. Limiting grooves 40 are formed at the ends of the protruding plate 35 and the pressure plate 37 that are far apart from each other.

[0051] A roller 39 is rotatably connected to the inner wall of the limiting groove 40. As the expansion frame 38 moves, the roller 39 pushes the protruding plate 35 and the semi-circular groove block 34 to move closer to each other. At this time, the fixing rope of the transport vehicle is placed into the movement of the protruding plate 35 and the semi-circular groove block 34 closer to each other. When the protruding plate 35 and the semi-circular groove block 34 come into contact with each other, the fixing rope will be squeezed and fixed. The bottom of the squeezing plate 22 is fixedly connected to the connecting plate 31, and the end of the connecting plate 31 is fixedly connected to the expansion frame 38.

[0052] The surface of the slider 30 is slidably connected to the inner wall of the groove 7. A pressure plate 37 is provided on the surface of the protruding plate 35. When the pressure plate 37 moves into the pressure groove 36, it will squeeze the fixing rope and cause it to bend, thereby increasing the friction between the fixing rope and the semi-circular groove block 34. The surface of the pressure plate 37 is inserted into the inner wall of the pressure groove 36. The surface of the roller 39 extends to the outer end of the limiting groove 40. The surface of the roller 39 contacts the inner wall of the expansion frame 38. The ends of the expansion frame 38 are set far apart from each other.

[0053] The limiting component 6 includes a second arc plate 51, the bottom of which is hinged to the top of the reinforcing plate 2. A grooved rod 53 is fixedly connected to the end of the first arc plate 50 away from the reinforcing plate 2, and a cylindrical rod 52 is fixedly connected to the end of the second arc plate 51 away from the reinforcing plate 2.

[0054] A slot 56 is provided at the end of the cylindrical rod 52 away from the arc plate 51. After the patient lies on top of the stretcher 1, the arc plate 50 and the arc plate 51 are pushed to move closer to each other. When the arc plate 50 and the arc plate 51 move closer to each other, the grooved rod 53 will be pushed to insert into the surface of the cylindrical rod 52. The inner wall of the slot 56 will contact the surface of the insertion plate 55. The insertion plate 55 is fixedly connected to the inner wall of the grooved rod 53. A magnetic plate 54 is inserted into the inner wall of the grooved rod 53.

[0055] The surface of the cylindrical rod 52 contacts the inner wall of the grooved rod 53. The magnetic suction plate 54 is inserted into the interior of the socket plate 55 to fix the grooved rod 53 and the cylindrical rod 52. The patient is fixed to the top of the stretcher 1 by the arc plate 1 and the arc plate 2 51 to prevent the patient from falling off when the stretcher 1 is used to transport the patient. The surface of the socket plate 55 contacts the inner wall of the slot 56. The magnetic suction plate 54 passes through the grooved rod 53 and extends into the interior of the grooved rod 53. The lower surface of the magnetic suction plate 54 contacts the inner wall of the socket plate 55.

[0056] When using stretcher 1, rescuers lift it using handle 3 to move it. To move stretcher 1 on the road, electric actuator 21 is activated to move it downwards. As actuator 21 moves downwards, it pushes the perforated frame 27 downwards via the compression plate 22. The perforated frame 27 rotates downwards on the surface of the cylindrical frame 24. This rotation of the cylindrical frame 24, via the rotating rod 23, causes the elastic frame 29 to rotate downwards. Once the bottom of the cylindrical frame 24 is lowered, the elastic frame 29 causes the casters 28 to contact the road surface, allowing stretcher 1 to move. The elastic frame 29 supports stretcher 1. When the casters 28 traverse uneven surfaces, the elastic frame 29 uses its elasticity to reduce the vibration experienced by stretcher 1. To minimize secondary injuries to the injured due to bumps, when encountering damaged road surfaces, the electric push rod 21 can be moved upwards to retract the elastic frame 29 to the bottom of the stretcher 1, improving the ease of retraction and allowing rescuers to quickly transport the stretcher to the patient. When the casters 28 contact the ground, the curved sliding plate 26 will rotate with the lever 23 to the end of the stretcher 1. After the elastic frame 29 is retracted to the bottom of the stretcher 1, the curved sliding plate 26 will rotate to the underside of the mounting frame 20. When the stretcher 1 is on snow or gravel surfaces, rescuers can pull the stretcher 1 using the carrying straps 10. The stretcher 1 slides on the snow or gravel using the curved sliding plate 26, improving the practicality of the stretcher 1. This allows for quick integration of the stretcher 1 with transport vehicles such as helicopters. During the quick-lock connection, the elastic frame 29 needs to be retracted to the bottom of the stretcher 1. At this time, the compression plate 22 will move upward. When the compression plate 22 moves upward, it pushes the expansion frame 38 upward through the linkage plate 31. When the expansion frame 38 moves upward, it will move against the surface of the roller 39. As the expansion frame 38 moves, the roller 39 pushes the protruding plate 35 and the semi-circular groove block 34 to move closer to each other. At this time, the fixing rope of the transport vehicle is placed into the movement of the protruding plate 35 and the semi-circular groove block 34 closer to each other. When the protruding plate 35 and the semi-circular groove block 34 come into contact, they will compress and fix the fixing rope, thereby fixing the stretcher 1 to the fixing rope of the transport vehicle. A pressure plate 37 is provided on the surface of the protruding plate 35. The pressure plate 37 moves into the interior of the pressure groove 36. The compression of the fixing ropes causes them to bend, increasing the friction between the fixing ropes and the semi-circular groove block 34, thus improving the stability of the stretcher 1. The elastic frame 29 is used to secure the stretcher 1 to the ropes of the transport vehicle, improving the ease of docking the stretcher 1 with the transport vehicle. After the patient lies on top of the stretcher 1, the first arc plate 50 and the second arc plate 51 are pushed closer together. This movement pushes the grooved rod 53 into the surface of the cylindrical rod 52, and the inner wall of the slot 56 contacts the surface of the insertion plate 55. At this time, the magnetic plate 54 is inserted into the insertion plate 55 to fix the grooved rod 53 and the cylindrical rod 52. The patient is thus secured to the top of the stretcher 1 using the first arc plate 50 and the second arc plate 51.To prevent the patient from slipping off when transported using stretcher 1, the contact between the patient's armpit and the surfaces of arc plate 1 (50) and arc plate 2 (51) prevents the patient from sliding on the surface of stretcher 1. When arc plate 1 (50) and arc plate 2 (51) are subjected to pressure from the patient, they generate an outward expanding force. At this time, the cylindrical rod 52 compresses the magnetic suction plate 54, and simultaneously, the grooved rod 53 compresses the magnetic suction plate 54 through the insertion plate 55. Under this force, the magnetic suction plate 54 is locked inside the grooved rod 53, improving the stability of the connection between arc plate 1 (50) and arc plate 2 (51).
