Description

A stretcher trolley adaptable to various transportation scenarios Technical Field

[0001] This utility model relates to a stretcher transfer device, specifically a stretcher cart that can be adapted to various transportation scenarios. Background Technology

[0002] A stretcher is a specialized piece of equipment used for medical emergency, patient transport, and nursing care. It is widely used in hospitals, emergency centers, ambulances, rehabilitation institutions, and other settings. Its main function is to safely and smoothly transport and transfer patients who are immobile or require medical monitoring, reducing the physical burden on medical staff and their families, while ensuring the safety and comfort of the patient.

[0003] Currently, the commonly used stretcher carts have a fixed connection between the stretcher bed and the cart body. When the patient who needs to be transferred is in an area that is inconvenient for the stretcher cart to enter, medical staff need to use the stretcher bed to transfer the patient to the corresponding area, and then transfer the patient to the stretcher cart for further movement, which greatly complicates the operation steps of medical staff. Summary of the Invention

[0004] The purpose of this invention is to provide a stretcher trolley adaptable to various transportation scenarios, thereby solving the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides a stretcher vehicle that can be adapted to multiple transportation scenarios, including a stretcher mechanism and a vehicle body mechanism, wherein the stretcher mechanism is detachably mounted on the vehicle body mechanism;

[0006] The stretcher mechanism includes a support frame and a bed board assembly. The support frame includes two sets of parallel support beams, which are fixedly connected by multiple sets of reinforcing plates. Handles are installed at both ends of the support beams. The bed board assembly includes a base plate, a horizontal support plate, and a flip-over support plate. The base plate is installed on the support frame by multiple sets of elastic connectors. The horizontal support plate is fixedly installed on the upper end of the base plate. The flip-over support plate is rotatably installed on the base plate and is flipped by a flipping assembly installed at the bottom of the base plate.

[0007] The vehicle body structure includes a supporting top plate, a supporting bottom frame, and two sets of telescopic frames. The supporting top plate engages with the bottom of the supporting beam via a rack and pinion assembly. A clamping mechanism for fixing the supporting bottom frame and the supporting beam is installed on the supporting top plate. Multiple sets of supporting wheels are installed at the bottom of the supporting bottom frame, and each set of supporting wheels is equipped with a foot brake. The two sets of telescopic frames are arranged between the supporting top plate and the supporting bottom frame in an X-shape. The upper end of the telescopic frame is rotatably connected to the positioning shaft at the bottom of the support frame, and its lower end is rotatably connected to the connecting column on the supporting bottom support plate.

[0008] As a further embodiment of this utility model, two sets of support columns are fixedly installed on one narrow side of the support frame, and two sets of moving wheels are installed on the other narrow side through the mounting columns.

[0009] As a further embodiment of this utility model, the elastic connector includes a damping link and a shock-absorbing spring;

[0010] The two ends of the multiple sets of damping links are fixedly connected to the bottom support plate and the top support plate, respectively. The shock absorber is arranged on the outside of the damping links to elastically connect the bottom support plate and the top support plate.

[0013] As a further embodiment of this utility model, the rack assembly includes a first meshing rack and a second meshing rack;

[0014] The first meshing rack is fixedly installed in the mounting groove at the bottom of the support beam, and the second meshing rack is fixedly installed at the upper end of the support top plate.

[0015] As a further embodiment of this utility model, the clamping mechanism includes a mounting block, a double threaded rod, and two sets of clamping blocks;

[0016] The mounting block is fixedly installed at the bottom of the support top plate, and two sets of clamping blocks are slidably installed on both sides of the support top plate. The middle part of the double threaded rod is rotatably connected to the connecting hole on the mounting block, and a set of external threads is mirrored on both sides of the rod body. The two sets of clamping blocks and the corresponding external threads form a helical pair transmission.

[0017] As a further embodiment of this utility model, multiple sets of limiting rods pass through the connecting holes on the mounting block and are fixedly connected to the mounting block, and two sets of clamping blocks are slidably installed at both ends of the multiple sets of limiting rods.

[0034] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0035] As shown in Figures 1 to 6, in this embodiment of the present invention, a stretcher trolley adaptable to multiple transportation scenarios includes a stretcher mechanism 100 and a vehicle body mechanism 200. The stretcher mechanism 100 is detachably mounted on the vehicle body mechanism 200. The stretcher mechanism 100 includes a support frame and a bed board assembly. The support frame includes two sets of parallel support beams 101, which are fixedly connected by multiple sets of reinforcing plates 106. Handles are installed at both ends of the support beams 101. The bed board assembly includes a base plate 102, a horizontal support plate 103, and a tilting support plate 104. Plastic sponges 300 are correspondingly installed on the horizontal support plate 103 and the tilting support plate 104 to support the patient. The base plate 102 is mounted on the support frame via multiple sets of elastic connectors, and the horizontal support plate 103 is fixedly mounted on the base plate. At the upper end of 102, the flipping tray 104 is rotatably mounted on the base, and is flipped by the flipping assembly mounted on the bottom of the base; the vehicle body mechanism 200 includes a supporting top plate 201, a supporting bottom frame 203 and two sets of telescopic frames 202. The supporting top plate 201 is engaged with the bottom of the supporting beam 101 through a rack assembly. The supporting top plate 201 is equipped with a clamping mechanism 400 for fixing the supporting bottom frame 203 and the supporting beam 101. The bottom of the supporting bottom frame 203 is equipped with multiple sets of supporting wheels 206, and each set of supporting wheels 206 is equipped with a foot brake. The two sets of telescopic frames 202 are arranged between the supporting top plate 201 and the supporting bottom frame 203 in an X-shape. The upper end of the telescopic frame 202 is rotatably connected to the positioning shaft 204 at the bottom of the support frame, and its lower end is rotatably connected to the connecting column 205 on the supporting bottom tray 102.

[0036] In use, this utility model can be adapted to different scenarios. When the road conditions facilitate the movement of the rollers, the stretcher mechanism 100 can be fixedly connected to the vehicle body mechanism 200, and the stretcher can be moved by pushing the vehicle body. When the road conditions do not facilitate the movement of the rollers, medical personnel can quickly operate by unlocking the clamping mechanism 400 to separate the support base frame 203 and the support beam 101. Medical personnel can then separate and disassemble the stretcher mechanism 100 from the vehicle body mechanism 200 to form a movable stretcher bed for individual use.

[0037] As shown in Figures 2 to 4, in this embodiment of the present invention, two sets of support columns 107 are fixedly installed on one narrow side of the support frame, and two sets of movable wheels 105 are installed on the other narrow side through the mounting columns. In this invention, when the stretcher mechanism 100 is disassembled from the vehicle body mechanism 200 and placed on the ground, the support frame can be supported by the two sets of movable wheels 105 and the two sets of support columns 107. The friction between the two sets of support columns 107 and the ground can keep the support frame in a stationary state. At the same time, when it is necessary to move the support frame, the side of the support frame with the mounting columns can be lifted, and the movement of the support frame can be achieved by pushing the movable wheels 105 to roll.

[0038] As shown in Figure 4, in this embodiment of the present invention, the elastic connector includes a damping link 112 and a shock-absorbing spring 113. The two ends of the multiple sets of damping links 112 are respectively fixedly connected to the bottom support plate 102 and the supporting top plate 201. The shock absorber is arranged on the outside of the damping link 112 and is used to elastically connect the bottom support plate 102 and the supporting top plate 201. The present invention elastically connects the bottom support plate 102 and the supporting top plate 201 by designing the damping link 112 and the shock-absorbing spring 113. The damping extension and contraction of the damping link 112 and the elastic extension and contraction of the shock-absorbing spring 113 reduce the impact on the patient when the vehicle body mechanism 200 moves, thus reducing the patient's discomfort.

[0039] As shown in Figure 3, in this embodiment of the present invention, the flipping assembly includes a telescopic cylinder 108, a drive block 109, a transmission rod 110, and a fixed shaft 111. The telescopic cylinder 108 is fixedly installed at the bottom of the base plate 102, the drive block 109 is fixedly installed at the end of the telescopic rod of the telescopic cylinder 108, and the fixed shaft 111 is fixedly installed at the bottom of the flipping tray 104. One end of the transmission rod 110 is rotatably connected to the drive block 109, and the other end is rotatably connected to the fixed shaft 111. The angle of the flipping tray 104 in this invention... The degree can be adjusted according to the actual requirements of patient transfer. During the adjustment process, the tilting tray 104 is tilted by controlling the extension stroke of the telescopic cylinder 108. For example, in this utility model, when the telescopic cylinder 108 retracts, the drive block 109 moves synchronously with the end of the telescopic rod of the telescopic cylinder 108 and drives the transmission shaft to rotate synchronously. The other end of the transmission shaft is on the fixed shaft 111 and drives the tilting tray to rotate accordingly. When the telescopic cylinder 108 retracts to its limit stroke, the tilting tray 104 is in a horizontal state.

[0040] As shown in Figures 5 and 6, in this embodiment of the present invention, the rack assembly includes a first meshing rack 114 and a second meshing rack 115. The first meshing rack 114 is fixedly installed in the mounting groove at the bottom of the support beam 101, and the second meshing rack 115 is fixedly installed at the upper end of the support top plate 201. In this invention, when the stretcher mechanism 100 is placed on the vehicle body mechanism 200, the first meshing rack 114 at the bottom of the support beam 101 engages and locks with the second meshing rack 115 at the upper end of the support top plate 201, so that the support beam 101 can be locked in a locked state on the horizontal plane of the support top plate 201, and the support beam 101 will not slip on the support top plate 201, thereby improving the stability of the support frame when placed on the support top plate 201.

[0041] Furthermore, the clamping mechanism 400 includes a mounting block 401, a double-threaded rod 403, and two sets of clamping blocks 404. The mounting block 401 is fixedly installed at the bottom of the supporting top plate 201. The two sets of clamping blocks 404 are slidably installed on both sides of the supporting top plate 201. The middle part of the double-threaded rod 403 is rotatably connected to the connecting hole on the mounting block 401. Both sides of the rod body are provided with a set of external threads. The two sets of clamping blocks 404 and the corresponding external threads form a helical pair transmission. After the medical staff completes the placement of the support frame on the supporting top plate 201, they can rotate the double-threaded rod 403 to drive the two sets of clamping blocks 404 to move closer to each other and clamp them on the supporting top plate 201 and both ends of the support frame. The clamping blocks 404 limit the upward movement of the support frame away from the supporting top plate 201. The engagement of the first meshing rack 114 and the second meshing rack 115 finally achieves the locking between the supporting top plate 201 and the support frame.

[0042] Furthermore, multiple sets of limiting rods 402 pass through the connecting holes on the mounting block 401 and are fixedly connected to the mounting block 401. Two sets of clamping blocks 404 are slidably installed at both ends of the multiple sets of limiting rods 402. By limiting the sliding of the limiting rods 402 and the clamping blocks 404, the stability of the clamping blocks 404 during sliding is improved. Of course, in actual design, a track for the clamping blocks 404 to slide can also be set at the bottom of the supporting top plate 201 to replace the limiting rods 402 selected in this utility model.

[0043] As shown in Figures 6 and 7, in this embodiment of the present invention, the telescopic frame 202 includes a movable frame 2021, a limiting frame 2022, a driving screw 2023, and a driving motor 2024. Both the movable frame 2021 and the limiting frame 2022 are U-shaped structures. The far ends of the movable frame 2021 and the limiting frame 2022 are rotatably connected to the positioning shaft 204 and the connecting column 2025, respectively. The lower end of the movable frame 2021 is slidably installed in a guide groove provided within the limiting frame 2022. The moving screw 2023 is rotatably installed inside the limiting frame 2022 and forms a helical transmission pair with the bottom of the movable frame 2021. The drive motor 2024 is fixedly installed at the bottom of the limiting frame 2022 and is used to drive the driving screw 2023 to rotate. When it is necessary to adjust the length of the telescopic frame 202, the drive motor 2024 can be turned on by controlling the drive motor 2024 to drive the driving screw 2023 to rotate, and the helical transmission will drive the movable frame 2021 to slide linearly within the limiting frame 2022.

[0044] In this utility model, both sets of telescopic frames 202 can be telescopically extended or retracted independently. By synchronously extending or shortening the two sets of telescopic frames 202, the height of the supporting top plate 201 and the stretcher mechanism 100 thereon can be adjusted. When a single telescopic frame 202 is extended or retracted, the tilt angle of the supporting top plate 201 and the stretcher mechanism 100 thereon can be adjusted.

[0045] In summary, this utility model provides a detachable stretcher mechanism 100 and a vehicle body mechanism 200, which can be flexibly adapted to the actual use scenario, allowing medical staff to assemble or disassemble the stretcher mechanism 100 and the vehicle body mechanism 200 for separate use.

[0046] 1. When the stretcher mechanism 100 is placed on the vehicle body mechanism 200, the meshing rack 114 on the bottom of the support beam 101 meshes and clamps with the meshing rack 115 on the upper end of the support top plate 201. At the same time, the two sets of clamping blocks 404 are mirrored and clamped to the two ends of the support top plate 201 and the support frame, locking the horizontal and vertical movement of the support frame, thereby completing the fixed assembly of the stretcher mechanism 100 and the vehicle body mechanism 200.

[0047] 2. When the stretcher mechanism 100 is to be used alone, the two sets of clamping blocks 404 can be driven to move away from each other and the support frame can be lifted to remove the support frame from the support top plate 201. The friction between the two sets of support columns 107 of the support frame and the ground can keep the support frame in a stationary state.

[0048] This solution also includes a controller, which is installed on the equipment. During use, each electrical device can be started and operated separately through the controller. The power connection method of each electrical device is a mature existing technology, and the control circuit of the controller can be implemented by simple programming by those skilled in the art. All of these are well-known technologies to those skilled in the art, and will not be elaborated further here.

[0049] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
