[0021] like Figures 1 to 5 As shown, the medical flatbed cart in the embodiment of the present application includes a stretcher 2 and a vehicle body 1.

[0022] The stretcher 2 is placed on the upper surface of the vehicle body 1. Specifically, the stretcher 2 includes a main rod 21 and a rigid chain 22. Two main rods 21 are provided. The two main rods 21 are arranged side by side at intervals. In this embodiment, the main rods 21 can be hollow long tubes, which can effectively reduce the overall weight of the stretcher 2.

[0023] refer to Figure 2 Specifically, a plurality of rigid chains 22 are provided, and the plurality of rigid chains 22 are arranged side by side and vertically between the two main rods 21. The end of the rigid chain 22 is vertically fixedly connected to a limit rod 23 along its length direction, and a limit spring block 24 is vertically arranged on the outer surface of the limit rod 23. The main rod 21 is provided with mounting holes 211 on both sides of the rod body, and the two sides perpendicular to the mounting holes 211 are provided with limit holes 212. The head end of the rigid chain 22 is rotatably connected to the mounting hole 211 of one of the main rods 21. Specifically in this embodiment, the head end of the rigid chain 22 is fixedly connected to a limit column 4 with a T-shaped axial cross section. The limit column 4 passes through the hole of the mounting hole 211 from the outside of the main rod 21 and is fixedly connected to the head end of the rigid chain 22. The end of the rigid chain 22 is rotatably connected through the limiting rod 23 through the mounting hole 211 of another main rod 21, and the limiting spring block 24 on the limiting rod 23 is aligned with the limiting hole 212. When it is necessary to change the soft or hard state of the rigid chain 22 to achieve the purpose of the soft or hard stretcher 2, the medical staff only needs to press the limiting spring block 24 and then rotate the limiting rod 23 at the end of the rigid chain 22 one hundred and eighty degrees. At the same time, the limiting spring block 24 will also be clamped on the limiting hole 212 below the main rod 21, effectively fixing the changed state of the rigid chain 22.

[0024] In this embodiment, the rigid chain 22 is a prior art, for example, the rigid transmission chain structure is the same as that in the patent document with publication number CN102182791A. The rigid transmission chain includes multiple groups of paired outer connecting plates, multiple groups of paired inner connecting plates arranged on the inner sides of the outer connecting plates, and multiple upper connecting shafts and lower connecting shafts; the outer connecting plates and the inner connecting plates are symmetrically provided with the same fillet on both sides of the upper edges, the lower edges are straight and parallel to the upper edges, and the left and right edges are perpendicular to the lower edges, the outer connecting plates and the inner connecting plates are symmetrically provided with left upper shaft holes and right upper shaft holes of the same diameter on the upper ends, and two semicircular holes are symmetrically provided on both sides of the lower ends, and the lower shaft hole is provided at the midpoint of the line connecting the centers of the two semicircular holes; the outer connecting plates are movably connected to the upper right shaft holes on a pair of inner connecting plates through the upper left shaft holes thereon in pairs via the upper connecting shafts, and the outer connecting plates are movably connected to the upper left shaft holes on another pair of inner connecting plates through the upper right shaft holes thereon in pairs via the upper connecting shafts, and the paired outer connecting plates and the inner connecting plates are connected through the lower shaft holes and the lower connecting shafts respectively; fixing devices are provided at both ends of the upper connecting shafts and the lower connecting shafts.

[0025] The stretcher 2 also includes a stretcher cloth 25 and a filling layer 26. The stretcher cloth 25 is wrapped around the two main rods 21 and the rigid chain 22. The filling layer 26 is arranged between the two main rods 21 and the two relatively rigid chains 22. In this embodiment, the filling layer 26 is made of a bendable material, such as multi-layer cotton cloth, sponge or silicone. The filling layer 26 can effectively prevent the patient from being stabbed when lying on the stretcher 2. At the same time, the outer surface of the rigid chain 22 is covered with a protective cloth cover 27. By such a setting, the comfort of the patient when lying flat can be further increased.

[0026] In order to facilitate the rotation of the limiting rod 23 , a rotating rod 28 is fixedly connected to the limiting rod 23 at the end of the limiting rod 23 extending out of the main rod 21 and perpendicular to the limiting rod 23 .

[0027] In addition, in order to prevent the stretcher 2 from causing secondary injury to the patient when placed on the vehicle body 1 in a bendable state, a placement plate 3 is provided on the upper surface of the vehicle body 1 .

[0028] The method of using the medical flatbed cart is as follows: when using it, according to the patient's condition, the rotating rod 28 is rotated to change the soft and hard state of the rigid chain 22, and then the medical staff lifts the stretcher 2 on the flatbed cart to achieve the purpose of transporting the patient together.

[0029] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of the present application should all be within the protection scope of the present application.
