Description
Technical Field
[0001] The present invention relates to the technical field of medical equipment, and particularly to a rotatable, telescopic, and liftable DR (Digital Radiography) examination bed with a slide rail system for a mobile vehicle-mounted hospital suitable for field rescue. Background Art
[0002] In field rescue and emergency medical situations, mobile vehicle-mounted hospitals have become an important means of medical rescue. However, existing vehicle-mounted DR examination beds are usually fixed and have a single function, unable to meet the rescue needs in complex environments. The wounded need to be carried on a stretcher up the steps and pass through the narrow entrance of the vehicle-mounted DR room (only 70 cm wide) for examination, which is a cumbersome process and poses a risk of secondary injury. In addition, existing examination beds lack flexible adjustment functions and cannot adapt to wounded patients of different body types and changing rescue environments. Summary of the Invention
[0003] The present invention discloses a rotatable, telescopic, and liftable DR examination bed with a slide rail system, aiming to solve the technical problem that existing examination beds lack flexible adjustment functions and cannot adapt to wounded patients of different body types and changing rescue environments.
[0004] To achieve the above object, the present invention adopts the following technical solutions:
[0005] A rotatable, telescopic, and liftable DR examination bed with a slide rail system includes a base. The outside of the base is fixedly connected with a controller. A round hole is opened on the base, and the inner wall of the round hole is fixedly connected with a double-raceway bearing. The inner wall of the double-raceway bearing is fixedly connected with a slewing support column. A slip ring is slidably connected to the outside of the slewing support column. The upper side of the slip ring is movably connected with a bed surface. A docking groove is opened on one side of the bed surface. A round groove is opened on the inner wall of the docking groove. A plurality of balls are arranged in the round groove, and sliding grooves are opened on both the top inner wall and the bottom inner wall of the docking groove. A convex block is arranged at one end of the docking groove close to the controller. A round hole is opened on the convex block, and a thin rod is arranged in the round hole. The end of the thin rod located outside the docking groove is fixedly connected with a pull ring. A rectangular opening is opened on the inner wall of the docking groove close to the controller, and a return spring is arranged in the rectangular opening. The return spring is located outside the thin rod.
[0006] By providing the docking groove, pull ring, return spring, balls, sliding grooves, and bed surface, when the wounded are carried over by a quick-release stretcher, the stretcher is translated on the bed surface through the docking groove. When the pull ring is pulled, the thin rod is pulled out. After the stretcher slides to the designated position, the pull ring is released, and the return spring will clamp the stretcher to prevent it from moving. After the wounded are transferred, the pull ring is pulled out again to remove the stretcher. The docking groove is provided with balls, which can make the docking of the stretcher smoother and faster, preventing multiple handling of the wounded and causing secondary injury to the wounded.
[0007] In a preferred embodiment, four symmetrically arranged first hydraulic rods are fixedly connected to the upper side of the base. The output ends of the four first hydraulic rods are fixedly connected to the same intermediate platform, and the upper side of the intermediate platform is fixedly connected to the bottom of the slip ring. One end of the bed surface close to the controller is provided with a hinge, and the end of the hinge away from the bed surface is fixedly connected to the headboard. Both the bottom of the headboard and the upper side of the intermediate platform are fixedly connected with two symmetrically arranged bosses, and the outer parts of the two bosses on the same side are movably connected to the same gas spring.
[0008] By providing the first hydraulic rods, the slip ring and the intermediate platform, when the first hydraulic rods are started, the hydraulic rods will lift the intermediate platform, and the slip ring on the intermediate platform will move the examination bed up and down, which can adapt to different examination angles and spatial layouts, facilitate the operation of medical staff, and improve work efficiency.
[0009] In a preferred embodiment, a telescopic groove is formed on one side of the bed surface away from the controller. The inner wall of the telescopic groove is fixedly connected with two symmetrically arranged sliding frames, and the same telescopic bed is slidably connected in the two sliding frames. The inner wall of one side of the telescopic groove close to the headboard is fixedly connected with two symmetrically arranged second hydraulic rods, and the output ends of the two second hydraulic rods are fixedly connected to the outside of the telescopic bed.
[0010] By providing the sliding frames, the telescopic bed, the telescopic groove and the second hydraulic rods, when the height of the wounded is relatively high, the second hydraulic rods are started, and the telescopic bed in the telescopic groove slides out to adapt to the wounded with different heights, improving the applicability of the examination bed.
[0011] In a preferred embodiment, two rollers are arranged on both sides of the bed surface, and railings are movably connected to the outside of the rollers. Grooves are formed at the ends of the railings away from the bed surface, and round rods are arranged in the grooves. The same handrail is movably connected to the outside of the round rods on the same side, and a plurality of equidistantly distributed safety belts are fixedly connected to the outside of the bed surface. A round opening is formed on the intermediate platform, and the inner wall of the round opening is movably connected to the slewing support column.
[0012] By providing the railings, the handrails and the safety belts, when the wounded are moved to the examination bed, the railings and the handrails can be raised, and the safety belts are fastened to the wounded to prevent the wounded from falling, improving the protection of the wounded.
[0013] As can be seen from the above, the DR examination bed with a rail system that can be rotated, telescoped and lifted provided by the present invention has the technical effect that when the wounded are carried over by a quick-release stretcher, the stretcher is translated on the bed surface through the docking groove, the pull ring is pulled, the thin rod is pulled out, after the stretcher slides to the designated position, the pull ring is released, and the return spring will lock the stretcher to prevent it from moving. After the wounded are transferred, the pull ring is pulled out again and the stretcher is taken out, which can make the docking of the stretcher smoother and faster and prevent secondary injuries caused by multiple handling of the wounded.
