[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1 As shown, the improved patient transport stretcher in this embodiment includes a base frame 1, a first pad 2, a second pad 3, a front handrail 4, a rear handrail 5, and casters 6. The first pad 2 and the second pad 3 are arranged adjacent to each other on the base frame 1. The front handrail 4 is located on the base frame 1 near the end of the first pad 2, and the rear handrail 5 is located on the base frame 1 near the end of the second pad 3. A caster 6 is movably provided on both sides of the base frame 1 near its front and rear ends via connecting components 7. The caster 6 can be a self-locking swivel caster.

[0028] Each side of the base frame 1 is equipped with a handrail 8, which is convenient for patients to hold on to and also prevents patients from falling off the side of the stretcher.

[0029] The top front end of the first pad 2 is provided with a headrest 9 to improve the comfort of the patient lying on the stretcher.

[0030] A telescopic rod 10 is provided on each side above the front handrail 4. The upper ends of the two telescopic rods 10 are connected by a U-shaped handrail 11. The telescopic rods 10 can be extended through the U-shaped handrail 11 to facilitate the movement of the stretcher.

[0031] like Figure 2-3 As shown, the connecting assembly 7 includes a connecting sleeve 71, a connecting block 72, and a support rod 73. The connecting sleeve 71 is rotatably fitted onto the outside of the base frame 1. The caster 6 is fixedly connected to the outer wall of the connecting sleeve 71 through the connecting block 72. The support rod 73 is fixedly and vertically arranged on the outer wall of the connecting block 72.

[0032] The side wall of the connecting sleeve 71 is provided with a through first positioning hole 74 along the horizontal radial direction, and the base frame 1 is provided with through second positioning holes 12 along the horizontal and vertical diameter directions respectively. The first positioning hole 74 and the second positioning hole 12 are connected through each other by a spring ball pin 75.

[0033] like Figure 4 As shown, a positioning seat 14 with multiple slots 13 is fixedly provided on both sides of the bottom of the first pad 2. A crossbar 15 is provided on the base frame 1 at the bottom of the first pad 2. A U-shaped frame 16 is rotatably provided on the crossbar 15. The top of the U-shaped frame 16 is engaged in the slots 13 on the positioning seat 14.

[0034] The first pad 2 is rotatably connected to both sides of the base frame 1 via a rotating frame 17. The base frame 1 also has a support plate 18 on one side of the crossbar 15 for supporting the U-shaped frame 16. By adjusting the position of the U-shaped frame 16 in different slots 13 and flipping the rotating frame 17, the first pad 2 can be adjusted to various tilt angles. After placing the U-shaped frame 16 on the support plate 18, the first pad 2 can be completely flattened.

[0035] This utility model, through the setting of casters 6 and connecting components 7, can realize the conversion of stretcher into different forms:

[0036] Figure 1 The diagram shows the stretcher in its moving position. At this time, the casters 6 are in the extended position. When the patient lies on the stretcher, the stretcher can be moved by pulling it through the U-shaped handrail 11, thereby reducing the workload of medical staff.

[0037] Figure 5 The diagram shows the fixed configuration of the stretcher. At this point, the spring top pin 75 can be pulled out, and the caster 6 can be rotated inward by 90° to make the caster 6 horizontal and the support rod 73 vertical. Then, the spring top pin 7 is inserted vertically through the first positioning hole 74 and the second positioning hole 12 to lock the positions of the caster 6 and the support rod 73. At this point, the stretcher becomes the traditional hand-carrying mode, and the support rod 73 provides support for the stretcher.

[0038] In summary, this utility model combines the traditional hand-carried stretcher and the mobile stretcher into one, with a simple overall structure, small footprint, and applicability to different usage scenarios, thus improving the flexibility and convenience of stretcher use.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
