Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a space self-adaptive medical transfer device. BACKGROUND

[0002] In the medical transfer scene, for the transfer needs of patients between different units such as beds, operating rooms, imaging departments (CT / MRI rooms), etc., the existing transfer bed and supporting bed plate technical solutions are mainly divided into the following four categories:

[0003] 1. Electric conveyor belt type transfer bed, the core design of this type of equipment is a height-adjustable transfer bed body with a telescopic ultra-thin conveyor belt bed plate. When operating, the conveyor belt bed plate needs to be extended into the gap between the patient's back and the original bed surface. Through the active conveying of the conveyor belt and the telescopic action of the bed plate, the patient is transferred to the transfer bed. However, in actual application, the process of extending the bed plate under the patient's body still causes slight extrusion and friction to the patient's body, which easily causes discomfort to postoperative, fractured or critically ill patients, and cannot achieve truly non-invasive transfer. At the same time, the driving system and metal structural parts of this type of equipment are not subjected to non-magnetic treatment, and cannot enter the strong magnetic field of the nuclear magnetic (MRI) room. Moreover, the transfer process still needs manual assistance to adjust the patient's body position, and cannot completely eliminate human intervention;

[0004] 2. Traditional operating room transfer bed, this is a classic transfer equipment that has been used in clinical practice for a long time. The bed body is usually 500-600mm wide and about 2000mm long, which is suitable for the size of the ordinary ward corridor. However, the flexible turning and reversing of the relatively wide bed body in the ward is poor. The early products have fixed bed height, and multiple people are needed to lift and move the patient to the bed surface, which not only has high labor intensity, but also has the risk of patient falling and body position injury. Although some improved types realize height adjustment, the core transfer method still cannot be separated from manual lifting and transfer, and the transfer efficiency is low and the invasiveness to the patient is strong;

[0005] 3. Direct transfer scheme of hospital ordinary sick bed, some hospitals use the mode of directly placing the patient on the original hospital sick bed and pushing it to the operating room and examination department. This scheme saves the bed transfer link, but when entering the CT, MRI and other imaging departments, the ordinary sick bed cannot be precisely docked with the examination bed, and medical staff still need to lift and move the patient to the examination bed surface. This process relies on human power throughout the transfer process, and the stability of the patient's body during the transfer process cannot be guaranteed, especially for patients with spinal injuries, fractures and critically ill patients;

[0006] 4. The manual transfer solution using ultra-thin carbon fiber bed boards: Designed for transfers in narrow gaps, an ultra-thin carbon fiber bed board has been developed. Its lightweight and high-strength properties allow it to be easily inserted under the patient. The bed board is equipped with pull ropes on both sides. During operation, the patient must first be assisted to turn over, and the bed board placed under the patient's back. Then, multiple people simultaneously pull the ropes to transfer the patient and bed board together to the target transport equipment or examination bed. While this solution simplifies the transfer tools, it relies entirely on manual operation. Uneven force during pulling can easily cause the patient's position to shift. Furthermore, the bed board itself lacks a fixing and limiting structure, posing a safety hazard of the patient slipping. Additionally, if the carbon fiber bed board has not undergone professional demagnetization treatment, it cannot be used in the MRI room.

[0007] The above solutions have obvious limitations in terms of non-invasiveness, ease of operation, and adaptability to different scenarios. Summary of the Invention

[0043] The above-mentioned technical solution of the present invention has the following beneficial effects: By setting up a transfer cart and a transfer bed, the present invention can control the transfer cart to move the transfer bed, which has the following advantages:

[0044] 1. Strong spatial adaptability, adaptable to all narrow scenes. The transport vehicle can be adjusted in length and width, and with the rotation of the hoisting frame, the hoisted equipment can be seamlessly connected with the bed within a 1.1m wide ward aisle and an 80cm bed spacing, without moving the bed or bedside table.

[0045] 2. The transfer is safe and non-invasive with a low risk of secondary injury. The system enables patients to be transferred without touching the ground, eliminating the need for manual handling or turning of patients. The self-locking components of the guardrails ensure stable transfer. The transfer bed is made of non-magnetic, high-transmittance material, allowing the patient to enter the CT, MRI and operating room without the need for secondary transfer, thus significantly reducing the risk of secondary injury.

[0046] 3. Seamless adaptation across all scenarios, filling gaps in processes: The system integrates adaptation capabilities for three major scenarios: medical, civilian, and emergency. The medical end is adapted to standard hospital beds, operating tables, and various imaging examination equipment. The civilian end can be adapted to home and ambulances. The emergency end, with its lightweight, small size, and wear-resistant characteristics, is adapted to narrow spaces, bulk transportation, and complex environments, realizing non-invasive transportation throughout the entire process of "home-ambulance-hospital" and "battlefield / disaster relief site-ambulance-hospital", filling the scenario gaps in existing technologies.

[0047] 4. The equipment has a high reusability rate and outstanding emergency replacement function. One transport vehicle can be adapted to multiple transfer bed boards for rotation. A single bed board can be used by patients for a long time, which greatly reduces the hospital's procurement and management costs. The guardrail components of the transfer bed board can be used directly as an emergency stretcher, filling the non-invasive transport needs when there is no transport vehicle, avoiding secondary trauma caused by simple stretchers, and improving the adaptability of emergency scenarios.

[0048] 5. Lightweight and easy to operate, highly practical, can be operated by a single person, suitable for patients who need to be bedridden for a long time after surgery, fractures, spinal injuries, etc., as well as battlefield / disaster relief casualties, and can also be used in home-based elderly care, health care and other places.

[0068] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0069] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0070] like Figures 1-18 As shown, an embodiment of the present invention provides a space-adaptive medical transport device, including a transport vehicle and a transport bed board suspended on the transport vehicle;

[0071] The transfer vehicle includes a top plate 1, and a rotatable lifting frame 2 is provided at the bottom of the top plate 1. The lifting frame 2 is connected to a height-adjustable hook 3 at its four corners by lifting ropes 14. At the bottom of the top plate 1, in a position away from the lifting frame 2, a first beam frame that can extend left and right is arranged laterally. The two ends of the first beam frame extend outwards from the top plate 1. At the two ends of the first beam frame, a second beam frame that can extend forward and backward is arranged longitudinally. At the bottom of the two ends of the second beam frame, mounting columns 6 are provided. The overall structure of the transfer vehicle is made of stainless steel and 316 stainless steel spliced ​​together. A traveling mechanism 7 is provided at the bottom of the mounting columns 6. The traveling mechanism is a caster wheel.

[0072] The transfer bed board includes a bed board body 8 and detachable guardrail assemblies 9 set on both sides of the bed board body 8; the bed board body 8 includes several boards, each board is connected end to end and hinged together, and the guardrail assemblies 9 are set on both sides of each board and fix the position of each board; both the bed board body 8 and the guardrail assemblies 9 are made of non-magnetic materials, and the materials of the bed board body 8 and the guardrail assemblies 9 are UPE or PEEK; the hooks 3 are hoisted on the guardrail assemblies 9 on both sides.

[0073] A rotating disk 10 is provided on the top plate 1. A mounting column 11 is provided at the bottom of the rotating disk 10. The hoisting frame 2 is fixedly connected to the mounting column 11. A worm gear 12 is provided at the top of the rotating disk 10. A rotatable first rotating rod group is horizontally placed on the top plate 1 above the corresponding rotating disk 10. A worm 13 is provided on the outer side of the first rotating rod group. The worm 13 and the worm gear 12 mesh with each other. The rotating disk 10 rotates under the cooperation of the worm 13 and the worm gear 12.

[0074] The first rotating rod group is controlled to rotate, and the worm gear 13 on the first rotating rod group will drive the worm wheel 12 to rotate, so that the rotating disk 10 can rotate 360°, thereby driving the hoisting frame 2 to rotate. In this way, the transfer bed board can rotate 0°-360° together with the hoisting frame 2, which can meet the seamless connection between the transfer vehicle and the carrier such as the hospital bed.

[0075] The hoisting frame 2 is a frame structure. A mounting plate 15 is located in the middle of the hoisting frame 2. The bottom of the mounting column 11 is fixedly connected to the top of the mounting plate 15. The hoisting frame 2 has rotatable guide wheels 16 on both sides of its front end and rear end. rotatable guide wheels 16 are also located on both sides of the rear end of the hoisting frame 2. rotatable steering wheels 17 are located on both sides of the middle of the top of the hoisting frame 2. Rotatable steering wheels 17 are also located on the rear of the top of the hoisting frame 2, inside the corresponding guide wheels 16. A movable plate 18 is located on the top of the hoisting frame 2, in front of the corresponding middle steering wheel 17. Four hoisting ropes 14 are also present. One end of each rope is fixedly installed on the rear side of the movable plate 18. Two ropes 14 pass around the middle steering wheel 17 and are respectively wound around the two front guide wheels 16. The two ropes 14 turn 180° along the middle steering wheel 17 and are wound around the front guide wheels 16. The other two ropes 14 pass around the rear steering wheel 17 and are respectively wound around the two rear guide wheels 16. The other two ropes 14 turn 90° with the rear steering wheel and are wound around the rear guide wheels 16. The four ropes 14 are all arranged hanging down after passing around each guide wheel 16. The hook is installed on the hanging end of the rope 14.

[0076] Driven by the two sets of steering wheels 17, the hoisting rope 14 can move synchronously and in the same direction as the movable plate 18. When the movable plate 18 moves forward, it pulls the hoisting rope 14 along the steering wheels 17 and the guide wheel 16 to perform line winding operations, thus controlling the hook 3 to move upward synchronously. When the movable plate 18 moves backward, it pulls the hoisting rope 14 along the steering wheels 17 and the guide wheel 16 to perform line unwinding operations, thus controlling the hook 3 to move downward synchronously.

[0077] The hoisting frame 2 has a first lead screw 19 at the front along the front-back direction. The top of the hoisting frame 2 has first slide rails 20 on both sides corresponding to the first lead screw 19. The two ends of the movable plate 18 have first sliders 21. The middle of the movable plate 18 has an installation block. The first sliders are installed on the first slide rails 20. The first lead screw 19 passes through the installation block. The rotation of the first lead screw 19 drives the movable plate 18 to move back and forth along the first slide rails 20. The movement of the movable plate 18 can control the hook 3 to move up and down synchronously.

[0078] The front end of the first lead screw 19 is also provided with a connecting rod 22 extending towards the front end of the hoisting frame 2, and the end of the connecting rod 22 is provided with a crank handle 23;

[0079] The crank 23 drives the connecting rod 22 and the first lead screw 19 to rotate. At this time, the movable plate 18 connected to the first lead screw 19 will move back and forth along the first slide rail 20 at the top of the hoisting frame 2, thereby controlling the position change of the height of the hook 3.

[0080] The lifting frame 2 is also equipped with vertical limiting heads 24 at the lower ends of its four ends. The limiting heads 24 are provided with vertical limiting holes. Each lifting rope 14 passes through the limiting holes after passing over each guide wheel 16. The hook 3 is located at the end of the lifting rope 14 that passes through the limiting holes. The limiting heads 24 and the limiting holes facilitate the fixing of the lifting rope 14, thereby ensuring the stability of the entire lifting rope 14 and avoiding excessive swaying during the lifting operation.

[0081] The first beam frame includes two crossbeams 25 arranged on the front and rear sides of the top plate 1. Two crossbeams 25 are arranged on each side, with the two crossbeams 25 on the same side facing opposite directions and staggered. The crossbeams 25 on the same side extend to the left and right outer sides of the top plate 1, respectively. The ends of the crossbeams 25 facing the same direction on the outer sides of the top plate 1 are fixedly connected by connecting plates 26. The second beam frame is respectively arranged on the connecting plates 26 on both sides. A rotatable second rotating rod assembly is also horizontally arranged at the bottom of the top plate 1 along the left and right directions. Second lead screws 27 are also arranged at the bottom of the top plate 1 on the front and rear sides corresponding to the second rotating rod assembly. Connecting blocks 28 are respectively arranged on one crossbeam 25 extending to the left on one side of the top plate 1 and another crossbeam 25 extending to the right on the other side. The connecting blocks 28 on both sides are connected to the second lead screws 27 on both sides of the bottom of the top plate 1. The two connecting blocks 28 are respectively arranged at the opposite ends of the second lead screws 27 on the crossbeams 25 extending to the left. 8 is connected to the left end of the front second lead screw 27, and the connecting block 28 on the right-extending crossbeam 25 is connected to the right end of the rear second lead screw 27. One end of the second rotating rod group is provided with a pulley 29, and both ends of the front second lead screw 27 are also provided with pulleys 29. The rear second lead screw 27 is also provided with a pulley 29 on the side opposite to the pulley 29 on the second rotating rod group. The pulley 29 on the second rotating rod group is connected to the pulley 29 at one end of the front second lead screw 27 through a belt 30. The pulley 29 at the other end of the front second lead screw 27 is also connected to the pulley 29 on the rear second lead screw 27 through a belt 30. The rotation of the second rotating rod group drives the two second lead screws 27 to rotate synchronously. The two second lead screws 27 rotate in the same direction and the thread directions of the two second lead screws 27 are opposite. The installation orientations of the two connecting blocks 28 are opposite. When the two second lead screws 27 rotate, the two connecting blocks 28 will also move in opposite directions.

[0082] On both sides of the bottom of the top plate 1, a second slide rail 31 is provided at the position corresponding to each crossbeam 25, arranged in the left and right direction. A second slider 32 is provided on the top of each crossbeam 25. The second slider 32 is installed on the second slide rail 31. The crossbeams on both sides of the top plate 1 move laterally along the second slide rail 31 under the drive of the second rotating rod group.

[0083] The second rotating rod assembly is driven to rotate, which in turn drives the front second lead screw 27 to rotate via the belt 30. The rotation of the front second lead screw 27 in turn drives the rear second lead screw 27 to rotate synchronously. The rotation of the two second lead screws 27 controls the connecting blocks 28 on the opposite crossbeams 25 to move in opposite directions. In this way, the opposite crossbeams 25 can move towards the center of the top plate 1 at the same time, or move away from the top plate 1 at the same time. This allows the crossbeams 25 on both sides to retract or expand in the left and right direction, that is, to control the position adjustment of the entire transfer vehicle in the length direction. The transfer vehicle can extend and retract in the length direction within the range of 1.1m-2.2m.

[0084] The second beam frame includes a front longitudinal beam 33 and a rear longitudinal beam 34 located at the bottom of the connecting plate 26. The front longitudinal beam 33 extends towards the front end of the connecting plate 26, and the rear longitudinal beam 34 extends towards the rear side of the connecting plate 26. The bottom of the front longitudinal beam 33 and the rear longitudinal beam 34 at the end away from the connecting plate 26 is provided with a base plate 35. The mounting column 6 is located at the bottom of the base plate 35. The top of the connecting plate 26 is provided with a gearbox 36. The connecting plate 26 is provided with a clearance opening at the position corresponding to the gearbox 36. Both the front longitudinal beam 33 and the rear longitudinal beam 34 are provided with racks 37. The lower end of the gear set in the gearbox 36 passes through the clearance opening and meshes with the racks 37 on the two longitudinal beams. The gearbox 36 between the two connecting plates 26 is driven to rotate by a third rotating rod group. The front longitudinal beam 33 and the rear longitudinal beam 34 move synchronously in the front and rear directions under the cooperation of the gearbox 36 and the racks 37.

[0085] Two front longitudinal beams 33 and two rear longitudinal beams 34 are provided on each side. The racks 37 are respectively provided on one of the longitudinal beams on both sides. The two racks 37 on the same side are opposite to each other and staggered.

[0086] The gear set inside the gearbox 36 includes a main gear 38. A third rotating rod assembly is connected to the main gears 38 on both sides. The main gear 38 is located in the gap between the left and right longitudinal beams and does not contact the rack 37. A first driven gear 39 is provided inside the gearbox 36 on the side corresponding to the main gear 38. The bottom of the first driven gear 39 meshes with the rack 37 on the front longitudinal beam 33. The first driven gear 39 also meshes with the main gear 38. The first driven gear 39 avoids the rack 37 on the rear longitudinal beam 34. A second driven gear 40 is also provided inside the gearbox 36 on the side corresponding to the first driven gear 39. The bottom of the second driven gear 40 meshes with the rack 37 on the rear longitudinal beam 34. The second driven gear 40 also meshes with the first driven gear 39. The second driven gear 40 avoids the rack 37 on the front longitudinal beam 33.

[0087] The connecting plate 26 is provided with a third slide rail 41 at the position corresponding to each longitudinal beam, and the bottom of the front longitudinal beam 33 and the rear longitudinal beam 34 is provided with a third slider 42. The third slider 42 of each longitudinal beam is respectively installed on its own third slide rail 41. The longitudinal beams on both sides of the connecting plate 26 move synchronously along the third slide rail 41 under the drive of the third rotating rod group.

[0088] The main gear 38, the first driven gear 39, and the second driven gear 40 are staggered and meshed with each other. That is, one side of the main gear 38 partially meshes with one side of the first driven gear 39, and one side of the first driven gear 39 partially meshes with one side of the second driven gear 40. The first driven gear 39 and the second driven gear 40 rotate along the rack 37 on the front longitudinal beam 33 and the rear longitudinal beam 34, respectively, and the gears do not interfere with each other. That is, the first driven gear 39 and the second driven gear 40 only mesh with the rack 37 on one side.

[0089] The third rotating rod group is driven to rotate, which controls the rotation of the main gear 38 in the gearboxes 36 on both sides. The main gear 38 rotates in the gap between the two racks 37 on the same side. The main gear 38 drives the first driven gear 39 to rotate, and the first driven gear 39 drives the second driven gear 40 to rotate. In this way, the direction of rotation of the first driven gear 39 is opposite to that of the second driven gear 40. When the two driven gears on the same side rotate, they will drive the racks 37 on the front longitudinal beam 33 and the rear longitudinal beam 34 to move in the front and rear directions, respectively. Since the two driven gears on the same side rotate in opposite directions, the front longitudinal beam 33 and the rear longitudinal beam 34 can be controlled to move towards the center of the connecting plate 26 at the same time, or to move away from the connecting plate 26 at the same time. In this way, the longitudinal beams on both sides can be contracted or expanded in the front and rear directions, that is, the position adjustment of the entire transfer vehicle in the width direction can be controlled. The transfer vehicle can extend and retract in the width direction within the range of 0.65m-1.25m.

[0090] The first rotating rod assembly includes a first sleeve rod 43 horizontally placed on the top plate 1. The first sleeve rod 43 is located above the rotating disk 10. The worm gear 13 is located outside the first sleeve rod 43. One end of the first sleeve rod 43 is provided with a telescopic first connecting rod 44. The first connecting rod 44 can rotate synchronously with the first sleeve rod 43.

[0091] The second rotating rod assembly includes a second sleeve rod 45 horizontally placed at the bottom of the top plate 1. One end of the second sleeve rod 45 is provided with a telescopic second connecting rod 46, which can rotate synchronously with the second sleeve rod 45.

[0092] The third rotating rod assembly includes a third sleeve rod 47 located at the bottom of the top plate 1. One end of the third sleeve rod 47 is provided with a telescopic third connecting rod 48. The third connecting rod 48 can rotate synchronously with the third sleeve rod 47. The ends of the third sleeve rod 47 and the third connecting rod 48 that are away from each other pass through the gearboxes 36 on both sides and are connected to the main gear 38 inside the gearboxes 36.

[0093] The first connecting rod 44, the second connecting rod 46, and the third connecting rod 48 have the same orientation. The top of the gearbox 36 and the top of the connecting plate 26, which have the same orientation as each connecting rod, are provided with rotating shaft seats. The top and bottom of the top plate 1 are also provided with rotating shaft seats. The first sleeve rod 43 is rotatably mounted on the rotating shaft seat on the top of the top plate 1. The first connecting rod 44 passes through the rotating shaft seat on the top of the gearbox 36. The second sleeve rod 45 and the second lead screw 27 are both mounted on the rotating shaft seat on the bottom of the top plate 1. The second connecting rod 46 passes through the rotating shaft seat on the top of the connecting plate 26.

[0094] The cross-sections of the first connecting rod 44, the second connecting rod 46, and the third connecting rod 48 are polygonal structures. The movable cavities inside the first sleeve rod 43, the second sleeve rod 45, and the third sleeve rod 47 are adapted to the shape of each connecting rod. The third connecting rod 48 and the third sleeve rod 47 pass through the belt 30 at the bottom of the top plate. Each of the first connecting rod 44, the second connecting rod 46, and the third connecting rod 48 is provided with a crank handle 49 at the end away from its respective sleeve rod. The pulley 29 is located at the end of the second sleeve rod 45.

[0095] This arrangement allows each rotating rod assembly to retract. When the crossbeam 25 retracts (i.e., the two crossbeams 25 move synchronously toward the top plate 1), each connecting rod is inserted into its respective sleeve rod. When the crossbeam 25 expands (i.e., the two crossbeams 25 move synchronously away from the top plate 1), each connecting rod extends out of its respective sleeve rod. In this way, each rotating rod assembly retracts as the crossbeam 25 moves.

[0096] The manual adjustment devices on the transport vehicle (i.e., the first rotating rod group, the second rotating rod group, the third rotating rod group, and the first lead screw) can also be controlled by a pneumatic control unit. That is, the above-mentioned manual adjustment devices are replaced with cylinders. An air pump can be installed on the frame of the entire transport vehicle. The air pump is powered by a battery pack and equipped with solenoid valves and control panels to realize the position adjustment of the entire transport vehicle structure. Alternatively, an electronic control component can be used, that is, the rotating rod groups and the first lead screw are driven by a motor. The motor is powered by a battery or other power supply equipment. After the transport vehicle is hoisted into the imaging equipment workroom with the bed board, the transport vehicle is moved and parked away from the magnetic field area.

[0097] The board consists of six panels, namely, head panel 50, chest panel 51, waist bridge panel 52, hip panel 53, thigh panel 54, and calf panel 55. The rear end of the head panel 50 has a clearance notch, and the front end of the calf panel 55 has a connector. The front and rear ends of the chest panel 51, waist bridge panel 52, hip panel 53, and thigh panel 54 also have connectors and clearance notches, respectively. The connectors and clearance notches of each panel are interlocked and connected by a hinge shaft. Each panel has a slot at its left and right ends, and a pull-out extension frame 56 is installed in the slot. The extension frame 56 has a vertically flip-up limiting hinge 57 at the end away from the panel. The guardrail assembly is placed on the extension frame 56, and the outer side of the guardrail assembly is fitted with the limiting hinge 57.

[0098] The buttocks plate 53 and thigh plate 54 have installation notches in the middle of their mating ends. The two installation notches cooperate to form a nursing notch. Sealing covers 78 are provided in both installation notches. The end of the sealing cover 78 located in the buttocks plate 56 is also provided with an avoidance notch. The end of the sealing cover 78 located in the thigh plate 54 is also provided with a connector. The connectors of the two sealing covers 78 are inserted into the avoidance notches. The hinge shaft connecting the buttocks plate 53 and thigh plate 54 passes through the joint between the connectors and the avoidance notches on the two sealing covers 78. The nursing area formed by the sealing cover 78 and the nursing notch can be mainly used for emergency nursing. In some special scenarios, the injured person who has been staying for a long time may not be able to be quickly arranged to the hospital for treatment and nursing. In this case, the sealing cover 78 can be opened according to the physiological needs of the injured person to allow for the discharge of urine and feces, thereby keeping the bed board clean and reducing the risk of infection.

[0099] The guardrail assembly includes a frame structure guardrail panel 58. A limiting mechanism is also provided on the lower end of the guardrail panel 58 on the side away from the limiting hinge 57. The guardrail assembly is fixed on the extension frame 56 under the limitation of the limiting hinge 57 and the limiting mechanism. The hook 3 is hoisted on the guardrail panel 58.

[0100] The bed board body 8 measures 52cm × 195cm. The extension stroke of the two side extension frames 56 is 6.5cm. After the two side extension frames 56 are pulled out, the width will increase by 13cm. At this time, the width of the bed board body 8 can be extended to 65cm, thus adapting to the width of most operating tables.

[0101] After removing the guardrail assembly 9 and placing the bed board body 8 on the hospital bed, auxiliary bed boards can be laid on both sides of the bed board body 8. The structure of the auxiliary bed boards is the same as that of the bed board body. They are also connected end to end by several auxiliary plates 79. The length of each auxiliary plate 79 is adapted to the length of its adjacent plate. The hinge axis between the auxiliary plates 79 also corresponds to the hinge axis position of the plate. The bottom of the auxiliary plate 79 is provided with a clearance groove 81 at the position corresponding to each extension frame 56. The clearance groove 81 at the bottom of the auxiliary plate 79 covers the top of the pulled-out extension frame 56.

[0102] The overall dimensions of the auxiliary bed board are 19cm × 195cm. Thus, the width of the two auxiliary bed boards combined with the bed board body 8 is 90cm, which is compatible with the width of standard hospital beds. Subsequently, a 90cm × 195cm × 5cm medical foam mattress 80 is laid on the board surface formed by the bed board body 8 and the auxiliary bed boards. The foam mattress 80 can adopt a split structure, with each foam mattress 80 adapted to the shape of the bed board body 8 and the two auxiliary bed boards respectively. This embodiment can adapt to the needs of conventional medical, civilian or emergency hospital beds. Both the main board and the auxiliary board are segmented hinged structures. The clearance groove 81 at the bottom of the auxiliary board 79 also covers the extension frame 56 on both sides of the bed board body 8. In this way, when the patient lies on the bed and performs functions such as getting up, lying down, raising legs, etc., the bed board body 8 and the auxiliary bed boards can change positions synchronously, thereby ensuring the stability of the entire bed board operation.

[0103] The overall weight of the bed board is 15kg-16kg, and the weight after installing the guardrail is ≤25kg. The lightweight design makes it easy to move.

[0104] The limiting mechanism includes an adjusting rod assembly disposed at the front end of the guardrail 58 and a limiting strip 59 disposed on the side of the guardrail 58 facing the board. The guardrail 58 is provided with a plurality of protruding first connectors 61 at its lower end on the side facing the board. The lower end of the limiting strip 59 is provided with a second connector 60 at the position corresponding to the gap between each first connector 61. The first connectors 61 and the second connectors 60 are hinged by a shaft. The adjusting rod assembly is movably connected to one end of the limiting strip 59.

[0105] The adjusting rod assembly includes a base block 62 fixed to the front end of the guardrail 58. An L-shaped operating handle 63 is provided on the upper front side of the base block 62. One end of the operating handle 63 is hinged to the upper end of the base block 62, and the other end extends forward of the base block 62. A linkage block 64 is hinged to the operating handle 63 at its included angle. A vertical movable groove 65 is provided on the front side of the base block 62 below the corresponding operating handle 63. A vertically movable linkage rod 66 is provided within the movable groove 65. The upper end of the moving rod 66 is hinged to the lower end of the linkage block 64. A notch 67 is provided on the lower part of the base block 62 facing the plate. The notch 67 is connected to the movable groove 65. A swing rod 68 is provided in the notch 67. The upper end of the swing rod 68 is hinged to the lower end of the linkage rod 66. The lower end of the swing rod 68 extends obliquely towards the plate along the notch 67. A hinge seat 69 is provided at the front end of the limiting strip 59 on the side facing the plate. The lower end of the swing rod 68 extends obliquely and is hinged to the hinge seat 69.

[0106] The operating handle 63 is arranged with one angled end facing downwards. The operating handle 63 has a mounting groove (not shown in the figure) on the end rod facing the base block 62. The connector at the upper end of the base block 62 is inserted into the mounting groove and the two (i.e., the operating handle 63 and the connector at the upper end of the base block 62) are hinged by a pin. The linkage block 64 is arranged at an angle. The upper end of the linkage block 64 is inserted into the mounting groove located at the angle and the two (i.e., the angle between the linkage block 64 and the operating handle 63) are also hinged by a pin. The lower end of the linkage block 64 is inclined towards the linkage rod 66 and is hinged to the upper end of the linkage rod 66 by a pin. The linkage rod 66, the swing rod 68 and the hinge seat 69 are also hinged by pins.

[0107] The front side of the base block 62 is provided with a limiting protrusion 70 at the position corresponding to the operation handle 63 and the linkage block 64. The limiting protrusion 70 can also be inserted into the mounting groove. Both the operation handle 63 and the limiting protrusion 70 are provided with a limiting hole 71 for mating insertion. A retaining pin that can be inserted into the limiting hole 71 is provided.

[0108] The extension bracket 56 includes extension rods 72 inserted into both sides of the slot, with a movable gap between the two extension rods 72. The two extension rods 72 are fixedly connected at their ends outside the plate by a connecting shaft. A limiting hinge 57 is provided at the movable gap, and a hinge joint 73 is provided at one end of the limiting hinge 57. The hinge joint 73 is rotatably mounted on the connecting shaft.

[0109] The hinge joint 73 is provided with a first arc-shaped platform 74 on both sides, and the extension rod 72 is provided with a second arc-shaped platform 75 at one end of the corresponding hinge joint 73. The first arc-shaped platform 74 and the second arc-shaped platform 75 are staggered and fitted together. The limiting hinge 57 rotates 180° up and down along the connected shaft under the restriction of the two arc-shaped platforms. When the limiting hinge 57 and the extension rod 72 are arranged perpendicularly, the two arc-shaped platforms contact each other and limit each other.

[0110] The limiting hinge 57 is provided with a limiting insertion hole 76, and the guard plate 58 is provided with a limiting protrusion 77 at the corresponding position of each limiting insertion hole 76. The limiting protrusion 77 is inserted into the insertion hole 76 of the limiting hinge 57, and the limiting strip 59 cooperates with the limiting hinge 57 to fix the position of the guard plate 58.

[0111] When installing the balustrade 58, first pull out the extension brackets 56 on both sides of each panel, then flip the limiting hinges 57 on each extension bracket 56 upwards. The two arc-shaped platforms work together to restrict the limiting hinges 57 to a vertical state. Then, place the balustrade 58 vertically on the extension brackets 56. The limiting protrusion 77 on the outer side of the balustrade 58 is inserted into the insertion hole 76 of the limiting hinge 57. Then, turn the operating handle 63 downwards. The operating handle 63 rotates along the upper end of the base block 62. When the operating handle 63 rotates, it will cause the linkage rod 66 to move downwards. When the linkage rod 66 moves downwards, it will drive the linkage rod 66 to move downwards in the movable groove 65. When the linkage rod 66 moves downwards, it will also cause the swing rod 68 to change position. Because the linkage rod 66 The lower end of 6 is hinged to the hinge seat 69 on the limiting strip 59, and the swing rod 68 will rotate, thereby driving the limiting strip 59 that is against the inner side of the guardrail 58 to rotate. At this time, the vertical limiting strip 59 can rotate to the horizontal state, and the end of the horizontal limiting strip 59 abuts against the end of the board. In this way, the guardrail 58 is fixed on the extension frame 56 with the cooperation of the limiting strip 59 and the limiting hinge 57. Finally, the retaining pin is inserted into the limiting protrusion 70 of the base block 62 through the limiting hole on the operating handle 63. In this way, the operating handle 63 can no longer rotate, and the limiting strip 59 is stuck between the guardrail 58 and the board. The extension frame 56 cannot move either, thus fixing the guardrail 58 to both sides of the bed board body 8.

[0112] The bed board body 8, with the railing 58 assembled, can be used as a stretcher in various scenarios, such as for transporting patients at home, or for moving the wounded in battlefields or disaster situations. The railing 58 is equipped with hanging holes, allowing for hoisting and transport via a transport vehicle. In disaster relief and emergency rescue scenarios, the entire bed board can be lifted by a rescue helicopter to complete rescue operations in special circumstances. When using the transport vehicle described in this application to transport the bed board, the patient can lie on the bed board, and the hook on the transport vehicle can be lowered and hung on... On the side rails of the bed board body, the hook 3 is then raised to lift the bed board body 8. The bed board body 8 can then be moved using a transport cart. The length and width of the transport cart can be adjusted according to the size of the space to transport the bed board body. The transport cart can then move the bed board body onto the operating table. During transport, the side sub-beds can be removed, and the side rails 58 can be installed. At this point, the bed board body 8 forms a stable whole. The transport cart is then used to lift the bed board and the patient together, and the patient is placed... After placing it on the operating table 83, the side panels 58 on both sides of the operating table 8 are removed again. Then, the limiting hinges 57 are rotated downwards to a vertically downward position. Instrument strips 84 are generally provided on both sides of the operating table 83. Movable blocks 85 are clamped on the instrument strips 84 and can slide along them. A positioning screw 86 is provided on the outward-facing side of the movable block 85. Moving the movable block 85 to the position corresponding to each limiting hinge 57 causes the downward-flipped limiting hinge 57 to rest against the outside of the movable block 85. Then, the positioning screw is used... The screw 86 passes through the insertion hole 76 on the limiting hinge 57 and is screwed onto the movable block 85. As the positioning screw 86 is continuously screwed in, the end of the positioning screw 86 will abut against the instrument side strip 84. In this way, the positioning screw 86 will fix the position of the movable block 85, thus completing the assembly of the bed board body 8 and the operating table 82. At this time, surgery can be performed directly. The bed board body can also be hoisted and moved to the CT machine or X-ray machine by a transport vehicle. Since the bed board body 8 and the railing are made of non-magnetic materials, the patient can undergo imaging examinations without leaving the bed board body.
