Description

Technical Field

[0001] This utility model relates to the field of medical and nursing supplies technology, and in particular to an electric patient transfer bed with one-button lifting. Background Technology

[0002] Patient transport beds are used in medical institutions to transfer patients between different departments, wards, and examination areas, and are considered essential clinical medical equipment. With the improvement of medical service levels, electric patient transport beds are gradually being used. These beds use electric drive devices to move and adjust the bed, reducing the manual labor required by nursing staff and improving the safety and comfort of patient transport. The electric design not only improves operational efficiency but also reduces the risk of accidents caused by manual operation to a certain extent.

[0003] Most existing electric patient transport beds are equipped with guardrails to protect patients during transport. Common guardrails are usually connected to the bed frame with bolts, clips, or fasteners. While these provide basic protection, in clinical practice, disassembling and reinstalling the guardrails often requires multiple steps and is cumbersome, especially when emergency care or rapid patient abduction is needed. The method of fixing the guardrails can easily cause operational delays, lacks flexibility, and hinders transport efficiency. Therefore, a one-button lifting and lowering electric patient transport bed is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an electric patient transfer bed with one-button lifting, which aims to improve the problems of cumbersome installation and disassembly steps and inflexible operation of the protective railing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An electric patient transport bed with one-button lifting and lowering includes a bed board, a base at the bottom of the bed board, a lifting assembly between the bed board and the base, an electric slide rail inside the bed board, a slider slidably connected inside the electric slide rail, a conveyor plate between the sliders, a protective mechanism on the side wall of the bed board, and a buffer mechanism on one side of the bed board. The protective mechanism includes a hinge frame, a rotating arm, and a positioning block. The hinge frame is fixedly connected to the side wall of the bed board, the rotating arm is rotatably connected inside the hinge frame, the positioning block is fixedly connected to the top of the bed board, a sleeve is fixedly connected to the side wall of the rotating arm, a fixed rod is fixedly connected inside the sleeve, a sliding rod is slidably connected inside the sleeve, a first spring is fixedly connected between the fixed rod and the sliding rod, and the side wall of the sliding rod is slidably connected inside the positioning block.

[0006] As a further description of the above technical solution: A collar is slidably connected to the side wall of the sleeve, and a connecting block is fixedly connected to the inner ring of the collar. The side wall of the connecting block is slidably connected to the inside of the sleeve, and the side wall of the connecting block is fixedly connected to the side wall of the slide rod.

[0007] As a further description of the above technical solution: The buffer mechanism includes a fixed frame and a buffer pad. The fixed frame is fixedly connected to the side wall of the bed board, and the side wall of the buffer pad is slidably connected inside the fixed frame. A mounting base is fixedly connected inside the fixed frame, and a damper is fixedly connected between the buffer pad and the mounting base.

[0008] As a further description of the above technical solution: The mounting base is internally fixedly connected to a guide rod, and the guide rod is slidably connected to two sliding sleeves. A second spring is sleeved on the side wall of the guide rod, and the second spring is fixedly connected between the two sliding sleeves.

[0009] As a further description of the above technical solution: The sliding sleeve sidewall is rotatably connected to a connecting plate, the connecting plate sidewall is rotatably connected to a fixing column, and the fixing column is fixedly connected to the buffer pad sidewall.

[0013] 2. In this utility model, through the cooperation between the fixed frame, buffer pad, mounting base, damper and guide rod and other structures, the buffer pad is able to be stably subjected to force and damped buffer under the action of external force.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-5This utility model provides an embodiment of a one-button lifting electric patient transport bed, including a bed board 1, a base 2 at the bottom of the bed board 1, and a lifting assembly between the bed board 1 and the base 2. The lifting assembly supports and adjusts the height of the bed board 1 to accommodate beds of different heights, thereby improving the flexibility of use. The lifting assembly includes a controller 3 and a hydraulic rod 4. The controller 3 is fixedly connected to the side wall of the bed board 1, and the hydraulic rod 4 is fixedly connected to the top of the base 2. The controller 3 is fixed to the side wall of the bed board 1 with screws, and the hydraulic rod 4 is fixed to the top of the base 2 by welding. The output end of the base 2 is fixedly connected to the lower surface of the bed board 1. The controller 3 and the hydraulic rod 4 are electrically connected to realize the extension and retraction of the hydraulic rod 4, thereby realizing the lifting and lowering of the bed board 1. The bed board 1 is equipped with a corrugated cover 5, which is fixedly connected between the bed board 1 and the base 2. The corrugated cover 5 can be extended and shortened through its own folds. At the same time, the corrugated cover 5 can be used to prevent dust and foreign objects from entering the extension and retraction parts of the hydraulic rod 4, avoiding damage to the rod and improving its service life. The bed board 1 is equipped with an electric slide rail 6, and a slider 7 is slidably connected inside the electric slide rail 6. A conveyor plate 8 is set between the sliders 7. The conveyor plate 8 is an existing technology that allows the patient to move horizontally through the conveyor belt on its surface. It will not be described in detail here. The electric slide rail 6 and the conveyor plate 8 slide in a straight line to achieve a smooth transfer of the patient and avoid secondary injuries caused by manual handling. The side wall of the bed board 1 is equipped with a protective mechanism, and a buffer mechanism is set on one side of the bed board 1. The protective mechanism includes a hinge frame 9, a rotating arm 17, and a positioning block 10. The hinge frame 9 is fixedly connected to the side wall of the bed board 1, and the rotating arm 17 is rotatably connected inside the hinge frame 9. The hinge frame 9 and the rotating arm 17 cooperate to rotate, allowing the protective mechanism to be raised or lowered as needed to protect the patient's safety. The positioning block 10 is fixedly connected to the top of the bed board 1. A sleeve 11 is fixedly connected to the side wall of the rotating arm 17. A fixing rod 12 is fixedly connected inside the sleeve 11, and a sliding rod 13 is slidably connected inside the sleeve 11. The fixing rod 12 and the sliding rod 13 are fixedly connected. A first spring 14 is fixedly connected to the slide rod 13, which provides cushioning and restoring force to ensure that the slide rod 13 can automatically return to its original position and prevent the protective mechanism from loosening. The side wall of the slide rod 13 is slidably connected to the inside of the positioning block 10. A collar 15 is slidably connected to the side wall of the sleeve 11. A connecting block 16 is fixedly connected to the inner ring of the collar 15. The side wall of the connecting block 16 is slidably connected to the inside of the sleeve 11 and fixedly connected to the side wall of the slide rod 13. The collar 15, the connecting block 16, and the slide rod 13 work together to achieve telescopic movement, so as to achieve the effect of rapid absorption when the patient rolls over or is impacted.

[0018] Reference Figure 6 and Figure 7The buffer mechanism includes a fixed frame 18 and a buffer pad 20. The fixed frame 18 is fixedly connected to the side wall of the bed board 1, and the side wall of the buffer pad 20 is slidably connected to the inside of the fixed frame 18. The buffer pad 20 is used to absorb external impact forces and prevent the front side of the transfer bed from being hit during movement, thus avoiding a large impact force. A mounting base 19 is fixedly connected inside the fixed frame 18, and a damper 21 is fixedly connected between the buffer pad 20 and the mounting base 19. The damper 21 is used to generate a damping effect when the buffer pad 20 is subjected to force and displacement, thereby effectively reducing the instantaneous impact force of external impacts and achieving slow energy absorption. A guide rod 22 is fixedly connected inside the mounting base 19, and two sliding sleeves 23 are slidably connected to the side wall of the guide rod 22. The sliding sleeves 23 slide along the axial direction of the guide rod 22, thereby driving the buffer pad 20 to move smoothly. To prevent swaying, a second spring 26 is fitted on the side wall of the guide rod 22. The second spring 26 is fixedly connected between the two sliding sleeves 23. The second spring 26 provides a reverse elastic force after the buffer pad 20 is compressed, thereby achieving automatic reset and ensuring that the buffer mechanism can return to its initial state after multiple impacts. A connecting plate 25 is rotatably connected to the side wall of the sliding sleeve 23. The connecting plate 25 can rotate with the movement of the sliding sleeve 23, thereby playing a role in transmitting and dispersing force during the buffering process. A fixing post 24 is rotatably connected to the side wall of the connecting plate 25. The fixing post 24 is fixedly connected to the side wall of the buffer pad 20. The fixing post 24 is used to connect the connecting plate 25 and the buffer pad 20, so that when the sliding sleeve 23 drives the connecting plate 25 to move, it can synchronously drive the buffer pad 20 to move, thereby achieving the effect of absorbing and dispersing the impact force.

[0019] Working principle: When using this device, the patient is first laid flat on top of the transfer plate 8. The device is then moved by pushing it. During this movement, when the front of the transfer bed is impacted, the buffer pad 20 slides inward into the fixed frame 18, transferring the impact force to the inside of the damper 21. Simultaneously, the connecting plate 25 deflects, causing the sliding sleeve 23 to slide outside the guide rod 22, thus deforming the second spring 26. After the impact force is relieved and dissipated by the damper 21, the second spring 26 and the damper 21 work together to reset the buffer pad 20 to prepare for any subsequent collisions. The transfer bed is then pushed to one side of the patient bed. When aligned, the hydraulic rod 4 is then controlled by the controller 3 to move the bed board 1 so that the bed board 1 is level with the bed surface. At this time, the sliding collar 15 can be used to make the collars 15 on both sides move relative to each other. Then, the connecting block 16 drives the slide rod 13 to move and pull it out from the inside of the positioning block 10. Then, the space on one side of the transfer bed is released by the deflection arm 17. Then, the electric slide rail 6 and the slider 7 cooperate to extend the transfer plate 8 outward and position it at the top of the bed. At this time, the conveyor belt inside the transfer plate 8 is activated to move the patient horizontally. At the same time, the transfer plate 8 is reset backward, thus smoothly transferring the patient to the bed.
