Description

Technical Field

[0001] This application relates to the field of emergency medical technology, and more specifically, to an emergency downstairs stretcher. Background Technology

[0002] Many buildings do not have elevators, so medical staff can only carry patients downstairs on stretchers or transport them down the stairs on stretcher carts.

[0003] Some existing stretchers have a single structural function and cannot be flexibly adjusted, so they can only be laid flat. In some buildings with narrow stairwells, medical staff usually stand at both ends of the stretcher when moving patients. Because the stretcher is long, it is very inconvenient to turn at the corners of the stairs, which leads to low rescue efficiency.

[0004] To address the aforementioned issues, this application provides an emergency downstairs stretcher. Utility Model Content

[0005] The emergency downstairs stretcher provided in this application adopts the following technical solution: An emergency downstairs stretcher includes a support plate, an adjustment mechanism on the outer side of the support plate, and the adjustment mechanism extends into the interior of the support plate. The adjustment mechanism includes a support frame, which is fixedly sleeved on the outside of a support plate. A soft pad and two connecting blocks are fixedly connected to the top of the support plate. Both connecting blocks are located behind the soft pad, and a rotating rod is embedded inside each connecting block. Two connecting slots are formed inside the support plate. A backrest and two gears are fixedly sleeved on the outside of the rotating rod. The bottoms of the two gears extend into the two connecting slots and are located on both sides of the backrest. Gears are meshed with gears at the bottom of each gear. Rollers are fixedly embedded inside the two gears. A fixing ring is fixedly sleeved on the outside of the roller. Multiple fixing slots are formed on the outside of the fixing ring. A spring telescopic rod is fixedly connected to the top of the support plate. An operating plate is fixedly connected to the top of the spring telescopic rod. A fixing rod is fixedly connected to the bottom of the operating plate. The bottom end of the fixing rod extends into one of the fixing slots. An operating handle is fixedly connected to one end of the roller. A connecting component is provided on the outside of the handle.

[0006] Furthermore, the connecting component includes a reinforcing block, which is fixedly connected to the bottom of the support plate and sleeved on the outside of the roller. The connection between the reinforcing block and the roller is movably connected by a bearing, and the connection between the rotating rod and the two connecting blocks is movably connected by a bearing.

[0007] By adopting the above technical solution and setting up reinforcing blocks, the rollers can be supported, thus making the rollers more stable when rotating.

[0008] Furthermore, a groove is provided on the front side of the support plate, a rotating shaft is embedded in the groove, an extension plate is fixedly sleeved on the outside of the rotating shaft, a guide frame is fixedly connected to the bottom of the support plate, and a support frame is sleeved on the outside of the guide frame.

[0009] By adopting the above technical solution and setting up a guide frame, the support frame can be both limited and supported.

[0010] Furthermore, a handle and a positioning block are fixedly connected to the bottom and one side of the support frame, respectively. The positioning block has a positioning groove inside. A telescopic rod is fixedly connected to the top of one side of the support plate. The telescopic rod is hollow inside.

[0011] Furthermore, a handle is fixedly connected to the top of the telescopic rod, and a spring and a pin are fixedly connected to the bottom of the handle. The bottom end of the spring is fixedly connected to the support plate, and the bottom end of the pin passes through the spring and the support plate and extends to the bottom of the support plate.

[0012] By adopting the above technical solution and setting a handle, the positioning block can be easily positioned later using a pin.

[0013] Furthermore, a U-shaped frame is fixedly sleeved on the outside of the support plate, an infusion stand is fixedly connected to the top of the U-shaped frame, and auxiliary straps are fixedly connected to both sides of the backrest, with buckles provided on the inner side of both auxiliary straps.

[0014] By adopting the above technical solution and setting two auxiliary straps, it is convenient to provide auxiliary fixation for the patient's upper body in the later stage, so as to avoid the situation of falling forward.

[0015] Furthermore, a plurality of silent casters are fixedly installed at the bottom of the support frame, and the plurality of silent casters are evenly distributed.

[0016] By adopting the above technical solution and setting multiple silent omnidirectional wheels, the efficiency of moving the stretcher cart is improved, and the generation of noise is reduced.

[0017] Compared with the prior art, the beneficial effects of this utility model are: During use, depending on the environment, grasp the control panel and pull it upwards. The fixing rod will move upwards along with it. Once the fixing rod disengages from the fixing ring, the roller can be rotated by turning the handle. When the backrest angle is adjusted to a suitable angle, stop turning the handle and release the control panel, allowing the fixing rod to return to its original position and extend into the corresponding fixing groove. The backrest is then positioned by the fixing ring. Based on this structure, patients can be transported in a seated position, significantly reducing the length of the device and making it easier to move in narrow stairwells. This improves the efficiency of transporting the device and the patient to the ambulance. Attached Figure Description

[0024] The implementation principle of this embodiment is as follows: During use, depending on the current environment, the operating plate 12 can be grasped and pulled upwards. The fixing rod 13 will move upwards together. At this time, the spring telescopic rod 11 is under force, and the telescopic end is in a stretched state. When the fixing rod 13 is separated from the fixing ring 10, the roller 9 can be rotated by turning the rocker handle 14, causing the two gears 8 to rotate. Since the two gears 7 mesh with the two gears 8 respectively, the angle of the backrest 6 can be adjusted by turning the rod 5. When the angle of the backrest 6 is adjusted to a suitable angle, the rocker handle 14 can be stopped and the operating plate 12 can be released. The spring telescopic rod 11 rebounds and drives the operating plate 12 to move downwards, so that the fixing rod 13 returns to its original state and extends into the corresponding fixing groove. The backrest 6 is positioned by the fixing ring 10. According to the above structure, the patient can be transported in a sitting position, which significantly reduces the length of the device and makes it easier to move in narrow stairwells. It has the purpose of improving the efficiency of transporting the device and the patient to the ambulance. Simultaneously, by pulling the handle 21 upwards, the pin 23 can be moved upwards. At this time, the telescopic rod 20 is in a stretched state, and the spring 22 is also in a stretched state. After the pin 23 is disengaged from the support plate 1, the support frame 18 can be pulled forward through the handle to support the extension plate 16. When the support frame 18 is in contact with the inner front wall of the guide frame 17, the handle 21 can be released. The spring 22 rebounds and moves the pin 23 downwards to extend into the positioning groove. The positioning block 19 positions the support frame 18, thus providing stable support for the extension plate 16. This makes the structure more stable during use and allows for sitting and lying positions, which is helpful for emergency rescue.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
