[0002] Medical transport equipment is a tool used to transport patients within or outside healthcare facilities. It is designed to ensure patient safety and comfort during transport, providing stable support and protection, especially in complex or emergency situations. Effective medical transport equipment can improve healthcare efficiency and reduce secondary injuries to patients during transport.

[0003] Traditional medical transport equipment typically includes a bed frame, support system, casters, fixation devices, and related auxiliary tools. The bed frame provides support for the patient, the support system ensures the patient remains stable during transport, the casters allow the equipment to move smoothly, and the fixation devices ensure that the patient's position on the equipment does not change unexpectedly, avoiding injuries caused by instability during transport.

[0004] Traditional medical transport equipment requires manual patient handling, often due to the complexity and weight of the equipment's design. While the equipment provides necessary support and stability, the process still relies heavily on the physical strength and skill of healthcare workers.

[0018] 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.

[0019] Reference Figures 1-3This utility model provides one embodiment: a medical electric transfer cart with a telescopic guide and positioning structure for the bed board, including a telescopic frame 1, which is made of Q235 carbon steel. The telescopic frame 1 serves to support the fixing frame 2, motor 3, telescopic assembly, and bed board assembly, providing overall structural support to ensure that the equipment does not deform or shift during patient transport. This is common knowledge and will not be elaborated further here. Multiple fixing frames 2 are fixedly connected to the side wall of the telescopic frame 1, and motors 3 are fixedly connected to the side walls of the fixing frames 2. The motors 3 are 12V DC geared motors, which provide stable rotational power to the output sprocket 4. Their deceleration characteristics can control the output... The output speed is adjusted to avoid excessive speed of chain 6 transmission, which could cause impact when the telescopic bed board 9 shifts, thus protecting patient safety. This is common knowledge and will not be elaborated further here. The output end of motor 3 is fixedly connected to output sprocket 4. Output sprocket 4 meshes with chain 6 through teeth, driving chain 6 to move along the outer periphery of output sprocket 4 and driven sprocket 5. At the same time, chain 6 drives driven sprocket 5 to rotate synchronously, forming a closed-loop power transmission path, achieving the effect of converting the rotational power of motor 3 into linear power of chain 6. Driven sprocket 5 is rotatably connected to the side wall of fixed frame 2. Chain 6 is provided on the outer wall of driven sprocket 5 and output sprocket 4. Telescopic components are provided on the side wall of chain 6. The telescopic assembly includes a slide 7, which transmits sliding power to the telescopic bed board 9 through a top fixing member 8, ensuring that the telescopic bed board 9 extends and retracts synchronously with the slide 7 to achieve a smooth movement effect. The side wall of the slide 7 is fixedly connected to the side wall of the chain 6, and the top of the slide 7 is fixedly connected to the fixing member 8. The top of the fixing member 8 is fixedly connected to the telescopic bed board 9, and the top of the telescopic frame 1 is provided with a bed board assembly.

[0020] Reference Figure 4 and Figure 5The bed board assembly includes an adjustable bed board 10, made of medical-grade ABS material. Its function is to directly support the patient's body and provide a mounting base for components such as the telescopic straps 11 and the fixing plate 14. Its smooth surface is resistant to disinfection and corrosion, preventing bacterial growth and cross-infection in the medical environment—a well-known fact, which will not be elaborated further here. The adjustable bed board 10 is located at the top of the telescopic frame 1. Multiple telescopic straps 11 are fixedly connected to the side walls of the adjustable bed board 10. These straps are made of medical-grade elastic nylon, and their function is to adapt to the fixation needs of patients of different body types through their elasticity, avoiding excessive tightness that compresses the patient or excessive looseness that leads to fixation failure. The nylon material is also wear-resistant and skin-friendly, reducing friction damage to the patient's skin—a well-known fact, which will not be elaborated further here. Each telescopic strap 11 has a fixed end connected to a support plate 12, and a positioning plate 13 is fixedly connected to the side wall of the support plate 12. The positioning plate 13 works in conjunction with the internal positioning mechanism of the buckle plate 19. The positioning groove 20 engages with the positioning plate 13. When the positioning plate 13 aligns with the positioning groove 20, the positioning groove 20 mechanically restricts the movement of the positioning plate 13, thereby fixing the length of the telescopic belt 11 and achieving the effect of firmly restraining the patient on the adjustable bed board 10. Multiple fixing plates 14 are fixedly connected to the side wall of the adjustable bed board 10. A fixing shaft 15 is fixedly connected between the multiple fixing plates 14. A rotating frame 16 is rotatably connected to the outer wall of the fixing shaft 15. A lower plate 17 is fixedly connected to the side wall of the rotating frame 16. A spring 18 is provided on the side wall of the lower plate 17. A buckle 19 is fixedly connected to the top of the rotating frame 16. The buckle 19 is used to cooperate with the positioning plate 13 through the internal positioning groove 20 to form a mechanical locking structure, preventing the positioning plate 13 from falling off during the transfer process and ensuring the reliability of the fixation. The buckle 19 has a positioning groove 20 inside. One end of the spring 18 is fixedly connected to the side wall of the adjustable bed board 10, and the other end of the adjustable bed board 10 is fixedly connected to the side wall of the lower plate 17.

[0021] Working principle: The output end of motor 3 drives the output sprocket 4 to rotate, and the output sprocket 4 drives the driven sprocket 5 to rotate synchronously through chain 6. The slide 7 fixed to the side wall of chain 6 moves along the guide path of telescopic frame 1 with chain 6. The top of slide 7 is fixedly connected to telescopic bed board 9 through fastener 8. The sliding of slide 7 drives telescopic bed board 9 to extend and retract synchronously. This process does not require medical staff to manually move the patient or the object to the target position, reducing the workload of medical staff and avoiding secondary injuries caused by manual handling. Pulling the telescopic belt 11 on the side wall of adjustable bed board 10 moves the support plate 12 fixed at one end and the positioning plate 13 on the side wall of the support plate. Until the positioning plate 13 is in contact with the position to be fixed, the fixing shaft 15 between the side wall fixing plates 14 of the adjustable bed board 10 provides a rotation fulcrum for the rotating frame 16. Press the buckle plate 19 on the top of the rotating frame 16, and the rotating frame 16 rotates around the fixing shaft 15. The lower plate 17 on the side wall of the rotating frame 16 compresses the springs 18 fixed on both sides. When the positioning groove 20 inside the buckle plate 19 is aligned with the positioning plate 13, the buckle plate 19 is released, and the spring 18 releases its elastic potential energy to push the lower plate 17 to reset, driving the rotating frame 16 and the buckle plate 19 to reset synchronously. The positioning groove 20 tightly engages with the positioning plate 13, thereby fixing the adjustable bed board 10 and the telescopic belt 11, preventing the parts from loosening during the transfer process, and ensuring safe transportation.
