[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0031] Example

[0032] This embodiment provides a multi-casualty emergency loading device, comprising: a moving mechanism 100, on which an emergency medical chamber 120 is mounted; and a loading and unloading mechanism 200, disposed within the emergency medical chamber 120, comprising a lifting assembly 210 and a connecting assembly 220. The lifting assembly 210 comprises at least two lead screws 211, which are spaced apart along a first direction X. The connecting assembly 220 comprises a support frame 221 and a loading platform 222. The two ends of the support frame 221 are slidably connected to at least two lead screws 211, and the loading platform 222 is slidably connected to the support frame 221 along the first direction X. A stretcher 400 is supported on the loading platform 222.

[0033] The stretcher support mechanism 300 includes a plurality of support rods 310, which are respectively connected to the side wall of the emergency cabin 120 and extend along the second direction Y. At least some of the support rods 310 are arranged along the height direction of the emergency cabin 120 to separate multiple layers of buffer space inside the emergency cabin 120.

[0034] The multi-patient emergency transport device described in this utility model establishes a transmission channel connecting the emergency cabin 120 and the ground through the lifting component 210 and connecting component 220 in the loading and unloading mechanism 200. This overcomes the problem of the high chassis of off-road vehicles and other transport vehicles affecting the efficiency of patient movement. Simultaneously, the stretcher support mechanism 300 fully utilizes the internal space of the emergency cabin 120, enabling the simultaneous transport of multiple supine patients, significantly improving transport efficiency. Furthermore, the stretcher support mechanism 300 works closely with the loading and unloading mechanism 200, ensuring patient stability during transport and improving patient comfort. Compared to conventional emergency transport equipment, this application offers significant advantages such as ease of operation, high transport efficiency, controllable movement, high space utilization, and reduced patient movement pain, providing a new structure and approach for emergency equipment configuration.

[0035] It is worth noting that, for ease of description, this embodiment defines the moving direction of the moving mechanism 100 as the first direction X, the width direction of the device as the second direction Y, and the height direction of the device as the third direction Z. The first direction X, the second direction Y, and the third direction Z are mutually perpendicular, and the first direction X and the second direction Y are located in the same plane. Furthermore, the conventional stretcher structure includes a support column 410, a support surface 420, and support legs 430. The support column 410 is located on both sides of the support surface 420 in the width direction, and the support legs 430 are located at the bottom of the support surface 420, with the injured person supported on the support surface 420.

[0036] See Figure 1 As shown, the mobile mechanism 100 in this embodiment also includes a vehicle body 110, and the emergency rescue cabin 120 is disposed on the vehicle body 110. A transmission port communicating with the outside is provided on one side of the emergency rescue cabin 120, and the loading and unloading mechanism 200 extends to the ground through the transmission port.

[0037] See Figure 2 and Figure 3 As shown, the stretcher support mechanism 300 in this embodiment is used to divide the interior of the emergency cabin 120 into multiple buffer spaces for accommodating the wounded. Specifically, the stretcher support mechanism 300 divides the interior of the emergency cabin 120 into six buffer spaces arranged in a 2×3 array, including two bottom buffer spaces 121, two middle buffer spaces 122, and two top buffer spaces 123, thereby enabling the simultaneous transfer of six wounded. Furthermore, in the second direction Y, a wounded transport channel is formed between two adjacent buffer spaces. The loading and unloading mechanism 200 is disposed in the transport channel and can move horizontally / vertically within the transport channel to move the wounded to the corresponding buffer space.

[0038] Specifically, in this embodiment, two support rods 310 are provided for each buffer space. Each support rod 310 includes a rod body 312 and a fixing part 311. The fixing part 311 is fixedly connected to one end of the rod body 312 and is detachably connected to the inner wall of the emergency cabin 120. Furthermore, in order to improve the support stability of the support rod 310, the support rod 310 in this embodiment also includes a fitting groove 313 and a limiting member 314. The fitting groove 313 is recessed downward from the upper surface of the rod body 312. The support column 410 of the stretcher 400 is fitted into the fitting groove 313. The limiting member 314 is disposed on one side of the fitting groove 313 to limit the movement distance of the stretcher 400.

[0039] See Figure 3 and Figure 4 As shown, the lifting assembly 210 in this embodiment includes a lifting driver 212, a connecting shaft 214, and a sliding connector 213. The sliding connector 213 is correspondingly sleeved on the lead screw 211. The end of the connecting shaft 214 is connected to the working end of the lifting driver 212 and passes through and connects to the sliding connector 213 to drive the sliding connector 213 to move along the lead screw 211. The support frame 221 is connected to the sliding connector 213. Further, the inner surface of the sliding connector 213 is threadedly engaged with the outer surface of the lead screw 211. A reversing gear set is provided between the sliding connector 213 and the connecting shaft 214. The connecting shaft 214 rotates around its axial direction through the lifting driver 212 to drive the sliding connector 213 to rotate around the axial direction of the lead screw 211 to which it is connected. Each end of the lead screw 211 is provided with a base 215, and the connecting shaft 214 passes through and connects to an adjacent base 215 in the second direction Y. Based on the above structure, the injured can move horizontally in the transport channel via the loading platform 222, and simultaneously move vertically via the support frame 221 and the lifting assembly 210.

[0040] See Figure 5As shown, to improve the fit between the stretcher and the loading platform 222 and the support frame 221, and to prevent misalignment or slippage between the connecting assembly 220 and the stretcher 400 due to patient movement or transport bumps, the loading platform 222 in this embodiment is provided with at least one guide groove 2221. The guide groove 2221 extends along the first direction X and is recessed downward from the upper surface of the loading platform 222. The support column 410 of the stretcher 400 is embedded in the guide groove 2221 and moves along the guide groove 2221. Correspondingly, the support frame 221 is provided with at least one docking groove 2211. The docking groove 2211 extends along the second direction Y and is recessed downward from the upper surface of the support frame 221. The stretcher 400 support leg 430 is embedded in the docking groove 2211, and the stretcher 400 enters the stretcher support mechanism 300 through the connecting assembly 220 via the docking groove 2211.

[0041] Figures 6-10 The diagrams illustrate the structure of the injured during different transport processes, allowing for adaptive adjustments to the order of patient allocation based on actual conditions. Furthermore, in different embodiments, the multi-patient emergency loading device may also include a control system. The moving mechanism 100 and the loading / unloading mechanism 200 are respectively connected to the control system, enabling operators to control the structure and movement process in real time, thereby improving the flexibility of the device.

[0042] In summary, the multi-patient emergency transport equipment described in this utility model establishes a transmission channel connecting the emergency cabin 120 and the ground through the lifting component 210 and connecting component 220 in the loading and unloading mechanism 200. This overcomes the problem of the high chassis of off-road vehicles and other transport vehicles affecting the efficiency of patient movement. Simultaneously, the stretcher support mechanism 300 fully utilizes the internal space of the emergency cabin 120, enabling the simultaneous transport of multiple supine patients, significantly improving transport efficiency. Furthermore, the stretcher support mechanism 300 works closely with the loading and unloading mechanism 200, ensuring patient stability during transport and improving patient comfort. Compared to conventional emergency transport equipment, this application offers significant advantages such as ease of operation, high transport efficiency, controllable movement, high space utilization, and reduced patient movement pain, providing a new structure and approach for the configuration of emergency equipment.
