Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a small trolley for ECMO transfer in hospitals. BACKGROUND

[0002] At present, when ECMO equipment is transferred, there is a lack of special and stable bearing tools, and ordinary trolleys are difficult to balance the fixation and running process of the equipment, which is easy to cause the equipment to shake, affect the normal operation of the equipment, and even threaten the safety of the patient's life. Oxygen cylinders are usually equipped during the transfer process. The existing solutions often cannot properly place the oxygen cylinders, neither ensuring the stability of the oxygen cylinders nor reasonably planning the layout of the oxygen cylinders and the ECMO equipment, resulting in unstable overall center of gravity during the transfer process, increasing the risk of rollover.

[0003] Through retrieval, a multifunctional vehicle for ECMO transfer is disclosed in Chinese Patent No. CN216232391U, which includes a base, a lifting mechanism fixedly connected to the upper end of one side of the base, an ECMO equipment placement box fixedly connected to the upper end of the tray, and an ECMO medical device and a connecting pipeline between the devices placed in the ECMO equipment placement box. The lifting mechanism includes an outer sleeve and a plug-in barrel. The outer sleeve is fixedly connected to the upper end of the base, and the plug-in barrel is fixedly connected to the bottom of the tray. The plug-in barrel is inserted into the outer sleeve, and a plurality of auxiliary instrument storage boxes are rotatably connected to the outer wall of the outer sleeve. The above-mentioned prior art sets the ECMO equipment placement box, which facilitates the storage and layout of the ECMO equipment, reduces the exposure of the pipeline, and facilitates the pipeline insulation while avoiding pulling the pipeline during the transfer process.

[0004] For the related technology in the above, the inventors found that the following deficiencies still exist: the above-mentioned device lacks in bearing stability and does not fully consider the optimization of the overall center of gravity. During the transfer process, if the road surface is bumpy or turns, the center of gravity of the equipment is easy to deviate, which may cause the vehicle to be unbalanced, posing a potential threat to the normal operation of the ECMO equipment and the safety of the patient. For oxygen cylinders, which are also critical auxiliary equipment during transfer, the multifunctional vehicle lacks a proper placement and fixation solution, making it difficult to meet the demand of safely transferring both the ECMO equipment and the oxygen cylinders during actual transfer.

[0024] The support assembly 3 further includes a front leg support column 307, a second roller 308, an electric control lifting rod 309, an adapter block 310 and a U-shaped support arm 311, the front leg support column 307 is fixed vertically at the bottom of the front end of the cart base 1, and a steerable second roller 308 is movably installed at the distal end of the front leg support column 307, the electric control lifting rod 309 is built in the inside of the front leg support column 307 and is rigidly connected with the U-shaped support arm 311 at a 90° angle through the adapter block 310, and the surface of the U-shaped support arm 311 is provided with a self-adaptive buckle mechanism.

[0025] The oxygen cylinder cage 304 adopts a sunken structure design, and the vertical center line thereof is located at 1 / 3 of the overall height of the cart base 1, and the oxygen cylinder cage 304 is coaxially nested with the positioning ring 303, so that the overall center of gravity of the loaded oxygen cylinder body 4 is located at a position below the center of the cart base.

[0026] The bottom of the cart base 1 is provided with a counterweight bin, which is filled with metal counterweight blocks, and the weight distribution satisfies that when the ECMO device is hung on the U-shaped support arm 311, the overall center of gravity of the cart is not more than 40% of the height of the base.

[0027] The electric control lifting rod 309 includes a pressure sensing module and an automatic balance controller, which automatically adjusts the extension amount of the lifting rod when detecting the change of the load of the U-shaped support arm 311, so that the cart base 1 always remains horizontal.

[0028] The inclined support plate 301 adopts a gradually changing cross-section design, the thickness of the upper part is 5mm and gradually increases to 8mm downward, and the connection between the inclined support plate 301 and the cart base 1 is provided with a triangular reinforcing rib 312, forming a double center of gravity stable structure.

[0029] Further explanation is needed:

[0030] That is, the support assembly 3 plays a crucial supporting and stabilizing role in the hospital ECMO transfer trolley. The inclined support plates 301 are symmetrically fixed on both sides of the trolley base 1 and form a 50° angle with the base plane. The first rollers 302 at the bottom not only ensure the flexibility of the trolley during movement, but also increase the support area and enhance the overall stability. The front leg support column 307 is vertically fixed to the bottom of the front end of the trolley base 1 and is matched with the second steering roller 308 to further improve the maneuverability and stability of the trolley. The positioning ring 303 is fixed to the bottom center of the trolley base 1 and is connected vertically with the oxygen cylinder cage 304. It not only plays a positioning role, but also assists in supporting the oxygen cylinder cage 304. The oxygen cylinder cage 304 adopts a sunken structure design, so that when the oxygen cylinder body 4 is loaded, the overall center of gravity is located below the center of the trolley base 1. In addition, the metal counterweight in the counterweight compartment at the bottom of the trolley base 1 ensures that the overall center of gravity of the trolley is reasonable when the ECMO equipment is suspended, effectively reducing the risk of rollover.

[0031] The support assembly 3 also has equipment protection and adjustment functions. The annular buffer pad 305 is arranged on the top bearing surface of the oxygen cylinder cage 304, which can effectively buffer the vibration and impact of the oxygen cylinder body 4 during placement and movement, protect the safety of the oxygen cylinder body 4, and prevent foreign matter from falling into the oxygen cylinder cage 304. The top cover 306 plays a further protective role for the oxygen cylinder body 4. The U-shaped support arm 311 fixes the ECMO equipment through the self-adaptive buckle mechanism to prevent it from shaking or falling during transfer. In addition, the electric control lifting rod 309 is internally provided with a pressure sensing module and an automatic balance controller. When the load change of the U-shaped support arm 311 is detected, the lifting rod can automatically adjust the extension amount, so that the trolley base 1 always maintains a horizontal state, providing a stable operating environment for the ECMO equipment and the oxygen cylinder body 4, and ensuring the safety and reliability of the transfer process.

[0032] The implementation principle of the hospital ECMO transfer trolley according to an embodiment of the present application is as follows:

[0033] Firstly, the medical staff places the oxygen cylinder body 4 in the sunken oxygen cylinder cage 304, the positioning ring 303 ensures the precise installation position, the annular buffer pad 305 plays a buffering protection role, the top cover 306 prevents foreign matter from falling in, and at the same time, the ECMO equipment is fixed through the self-adaptive buckle mechanism on the surface of the U-shaped support arm 311. At this time, the metal counterweight in the counterweight compartment at the bottom of the trolley base 1, combined with the sunken structure of the oxygen cylinder cage 304, makes the overall center of gravity of the trolley at a lower and reasonable position, ready for movement.

[0034] Secondly, the medical staff holds the trolley handle 2 to push the trolley, the first roller 302 at the bottom of the inclined support plate 301 and the second roller 308 at the end of the front leg support column 307 can turn together to make the trolley flexible in different environments. The inclined support plate 301 forms a 50° angle with the base plane, and together with the front leg support column 307, it provides a stable support structure for the trolley during movement.

[0035] Then, when the ECMO device is placed on the U-shaped support arm 311, its weight will change the center of gravity of the trolley. At this time, the pressure sensing module in the electric control lifting rod 309 plays a role. After detecting the load change of the U-shaped support arm 311, the automatic balance controller quickly responds by adjusting the extension amount of the lifting rod, so that the trolley base 1 always maintains a horizontal state, maintains the stability of the overall center of gravity, and avoids the trolley from tipping over due to the shift of the center of gravity.

[0036] Next, during the entire transfer process, the self-adaptive buckle mechanism of the U-shaped support arm 311 firmly fixes the ECMO device to prevent it from shaking or falling off. At the same time, the oxygen cylinder placement cage 304 also stably carries the oxygen cylinder body 4, ensuring the safety of the device during movement.

[0037] Finally, the annular buffer pad 305 always plays a buffering and protective role for the oxygen cylinder body 4 to avoid damage due to collision, and the triangular reinforcing ribs and other structures enhance the strength of the connection between the inclined support plate 301 and the trolley base 1, further ensuring the stability of the trolley during operation, and ensuring the safe and reliable operation of the ECMO transfer work.

[0038] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
