[0002] ECMO mainly consists of endovascular cannulas, connecting tubing, a power pump (artificial heart), an oxygenator (artificial lung), oxygen supply tubing, and a monitoring system. The oxygenator (artificial lung) oxygenates the infused blood and outputs oxygenated arterial blood. Hollow fiber membrane lungs, currently the most commonly used form of extracorporeal oxygenator, are characterized by easy degassing, high gas throughput, and strong oxygenation capacity. During the production, research, and optimization of oxygenators, extracorporeal circulation simulation experiments are conducted on oxygenators with different parameters and specifications. The performance indicators of the oxygenator are then evaluated by detecting the parameters of blood samples from the simulation experiments.

[0003] Existing technology CN223311474U discloses a miniature extracorporeal membrane oxygenation (ECMO) device, comprising a circulation pump, an oxygenator, and a heat exchanger respectively mounted on a base.

The outlet of the heat exchanger is connected to the inlet of the oxygenator via a first pipe, and the outlet of the oxygenator is connected to the inlet of the heat exchanger via a second pipe. The circulation pump is installed on the first pipe. The oxygenator has an oxygenation port in the middle, and an air inlet pipe is installed in the oxygenation port and connected to an air supply device. All the accessories of this oxygenation device are placed on the base.

[0010] Furthermore, an anti-bump unit is installed at the lower end of the trench. The anti-bump unit includes two pairs of movable tubes. The lower end of the movable tube is fixed to the lower end of the trench, and the upper end of the movable tube is fixed to the lower end of the moving block. A spiral beryllium copper wire is attached to the outside of the movable tube. Each side of the spiral beryllium copper wire is connected to the lower end of the moving block and one side of the movable tube. One side of the movable tube is connected to a channel. The upper end of a pair of channels on the same side passes through a concave platform and connects to a silicone shell. The lower end of the silicone shell is fixed to the concave platform. Multiple silicone protrusions are installed at the upper end of the silicone shell. The multiple silicone protrusions are in close contact with the lower end of the support.

[0011] Furthermore, two pairs of uprights are fixedly connected to the corner of the base, and a baffle plate is fixedly connected to the upper end of the uprights. The baffle plate matches the opening at the upper end of the cover. Two pairs of electric telescopic rods are embedded in the inner wall of the cover. The movable end of the electric telescopic rod is fixedly connected to the baffle plate. A control panel is installed on the outer wall of the cover.

[0012] The beneficial effects of this invention are as follows: 1. The present invention can enclose the entire device by installing a cover and a shield, thereby effectively isolating the device from the outside world and preventing dust accumulation on the surface due to prolonged placement. This eliminates the need for frequent cleaning. Furthermore, the installation of hubs and other components allows the device to be moved directly to a designated location by pushing or dragging without the need for manual or equipment assistance, saving time and effort and greatly improving the ease of use. 2. In this invention, the movable platform is moved by dragging a pull block with a handle. After the movable platform moves the moving platform out of the movable opening, the moving platform rotates in the U-shaped opening around the pin rod under the cooperation of weight until the supporting defense unit on one side of the moving platform is in contact with the ground. When the supporting defense unit extends, one of the extension blocks is dragged inside the supporting platform, causing the interlocking block inside the extension block to pull the rotating disk to rotate. The interlocking block inside the other extension block also engages with the rotating disk, allowing a pair of extension blocks to extend from both sides inside the supporting platform. When both extension blocks are fully extended, the extension... The protrusions on the same side as the support platform are in contact with the ground to achieve anti-slip purpose. The flip support platform pulls the rotating platform and rotating column to rotate on one side of the movable platform, allowing the extension block and support platform to adjust themselves according to the ground inclination angle, thereby enhancing the stability of the support. The rotating handle pulls the screw to rotate and passes through the fitting interface to contact the movable platform. When the movable platform is pressed, it will press the support platform at the lower end, pressing the support platform and a pair of extension blocks tightly against the ground, enhancing the stability of the equipment support. The extension blocks and support platform work together to perform support, increasing the support range. The entire structure is convenient to use and provides stable support. During equipment transfer, when the frame and support platform experience bumps due to road conditions, the impact is transferred to the cover via the concave platform and support seats. The cover is then pulled downwards by two pairs of connecting rods, causing the movable blocks to move. As the movable blocks move downwards in the trench, they compress the two pairs of movable tubes and two pairs of spiral beryllium copper wires. This compression of the spiral beryllium copper wires provides upward support to the movable blocks, reducing the impact on the movable blocks and support seats, and consequently reducing the impact on the cover. During the compression and shortening of the movable tubes, the air inside can be transported through channels to the silicone shell, causing the silicone shell to expand. The lower end of the support seat is supported to reduce the vibration between the support seat and the cover, preventing the cover from moving back and forth too much vertically. This enhances the vibration reduction effect of the cover and ensures the safe transfer of the equipment. It also assists in the placement of several silicone protrusions on the upper end of the silicone shell to prevent the lower end of the support seat from slipping between the silicone shell and the support seat, which would cause instability. When the equipment moves upward under the support, the deformation of the spiral beryllium copper wire supports the moving block, allowing the movable tube to extend. Some air inside the silicone shell returns to the movable tube through the channel, thus achieving the effect of stable support for the equipment. When removing the support from the equipment, rotate the handle in the opposite direction, causing the handle to pull the lead screw to rotate upwards until the lower end of the lead screw moves away from the locking interface on the moving platform. At this point, the moving platform is in a self-moving state. Then, press the extension block on one side of the support platform. The extension block rotates through the engagement block, and the extension block on the other side can move together, allowing both extension blocks to move into the support platform. Then, grasp the handle and press the traction block, causing the traction block to pull the moving platform into the moving opening. During the movement of the moving platform, the moving platform is supported at the opening of the moving opening and twists until the moving platform pulls the support platform into the U-shaped opening at the bottom of the moving platform. Then, press the traction block, causing the traction block to pull the moving platform and the support and defense unit to move into the moving opening and be retracted. Therefore, when the equipment is not supported, the parts can be retracted to ensure the normal transfer of the equipment.

[0017] Reference Figures 1-3 A cover 8 is installed on the outside of the base 1. The base 1 can move vertically inside the cover 8. Two pairs of columns 7 are fixedly connected to the corner of the base 1. A baffle 9 is fixedly connected to the upper end of the column 7. The baffle 9 fits into the opening at the upper end of the cover 8. Two pairs of electric telescopic rods 27 are embedded in the inner wall of the cover 8. The movable end of the electric telescopic rod 27 is fixedly connected to the baffle 9. A control panel is installed on the outer wall of the cover 8. The electric telescopic rods 27, the control panel and the power supply box are electrically connected.

[0018] When the equipment is moved to the usage location, the electric telescopic rod 27 is extended via the control panel, and the cover plate 9 is moved up. With the cooperation of the column 7, the accessories on the base 1 are moved out of the cover 8, and the equipment can be used. After use, the electric telescopic rod 27 is shortened via the control panel, and the cover plate 9 is lowered to put the accessories on the base 1 into the cover 8, which greatly improves the protection of the equipment and is very convenient to use.

[0019] Reference Figures 2-5The lower end of the cover 8 is fixedly connected to the support base 10. The lower end of the support base 10 is equipped with a bearing platform 11. A concave platform 14 is fixedly connected to the bearing platform 11. A groove 15 is reserved in the center of the concave platform 14. A movable block 16 is movably installed in the groove 15. A connecting rod 17 is fixedly connected to the corner position of the upper end of the movable block 16. The upper ends of the two pairs of connecting rods 17 are fixedly connected to the lower end of the support base 10.

[0020] The support platform 11 is fixed to the frame 12 on both sides, and the frame 12 has a triangular structure. Wheel hubs 13 are installed on both sides of the frame 12, and grooves are reserved on the outer circumference of the wheel hubs 13. By pulling the handle on one side of the frame 12, the support platform 11 pulls the wheel hubs 13 at the lower end of the frame 12 to rotate. The control on the outside of the wheel hub 13 is used to enhance its grip and facilitate the movement of the equipment.

[0021] Reference Figure 6 An anti-bump unit 18 is installed at the lower end of the trench 15. The anti-bump unit 18 includes two pairs of movable tubes 181. The lower end of the movable tube 181 is fixed to the lower end of the trench 15, and the upper end of the movable tube 181 is fixed to the lower end of the variable block 16. A spiral beryllium copper wire 182 is attached to the outside of the movable tube 181. Both sides of the spiral beryllium copper wire 182 are connected to the lower end of the variable block 16 and one side of the movable tube 181. One side of the movable tube 181 is connected to a channel 183. The upper end of a pair of channels 183 on the same side passes through a concave platform 14 and connects to a silicone shell 184. The lower end of the silicone shell 184 is fixed to the concave platform 14. Multiple silicone protrusions 185 are installed on the upper end of the silicone shell 184. The multiple silicone protrusions 185 are in close contact with the lower end of the support seat 10.

[0022] The cover 8 is pulled downward by two pairs of connecting rods 17 to move the variable block 16. During the downward movement of the variable block 16 in the trench 15, it presses down on two pairs of movable tubes 181 and two pairs of spiral beryllium copper wires 182. After being pressed, the spiral beryllium copper wires 182 provide upward support for the variable block 16, which can reduce the bumps on the variable block 16 and the support seat 10, and then reduce the bumps on the cover 8. The trench 15 constrains the variable block 16, which enhances the smoothness of the variable block 16 pulling the movable tubes 181 to extend or shorten. Air in the active tube 181 is transported to the silicone shell 184 through the channel 183. The silicone shell 184 expands to support the lower end of the support seat 10, which can reduce the impact on the support seat 10 and the cover 8, prevent the cover 8 from moving back and forth vertically, thereby enhancing the purpose of reducing the impact of the equipment and ensuring the safe transfer of the equipment. It works in conjunction with several silicone protrusions 185 on the upper end of the silicone shell 184 to prevent the lower end of the support seat 10 and the silicone shell 184 from sliding sideways and causing unstable support.

[0023] Reference Figures 7-9The support platform 11 has a pre-reserved opening 19, in which a movable platform 20 is movably mounted. A pulling unit 21 is mounted on the movable platform 20. A U-shaped opening 25 is pre-reserved at the lower end of the movable platform 20. Two sides of the U-shaped opening 25 are connected to a movable platform 24 via pins. A support and defense unit 26 is mounted on one side of the movable platform 24. When the movable platform 20 moves the movable platform 24 out of the opening 19, the movable platform 24, under the assistance of its weight, rotates around the pins in the U-shaped opening 25 until the support and defense unit 26 on one side of the movable platform 24 is in contact with the ground, thus facilitating the adjustment of the tilt angle of the movable platform 24.

[0024] The pulling unit 21 includes a pulling block 211, which is fixedly connected to the movable platform 20. A handle 212 is fixedly connected to the pulling block 211, and constraint posts 213 are fixedly connected to both sides of the other end of the pulling block 211. The constraint posts 213 are movably fitted into pre-drilled holes on the support platform 11. By pulling the pulling block 211 with the handle 212, the pulling block 211 pulls the movable platform 20 to move in the movable port 19. The movable port 19 constrains the movable platform 20, assisting the pulling block 211 in pulling the pair of constraint posts 213 to move in the holes on the support platform 11, thereby enhancing the smoothness of the movement of the movable platform 20 pulling the movable platform 24.

[0025] The upper end of the variable platform 20 is reserved with a fitting interface 22. One side of the concave platform 14 is fixed to the top of the pulling unit 21 with a stop unit 23. The stop unit 23 includes a support 231, which is fixed to one side of the concave platform 14. A threaded tube 232 is fixed to the center of the support 231. A lead screw 233 is connected to the threaded tube 232. A handle 234 is fixed to the top of the lead screw 233. The lower end of the lead screw 233 is arched and can be fitted into the fitting interface 22.

[0026] The rotating handle 234 drives the lead screw 233 to rotate in the lead screw cylinder 232, causing the lead screw 233 to move downward and pass through the insertion interface 22, thereby stopping the movable platform 20 to prevent the movable platform 20 from moving on its own in the movable port 19. The lower end of the lead screw 233 is arched, and during the downward movement of the lead screw 233, it can press the movable platform 24, so that the movable platform 24 pulls and supports the defense unit 26 to press it firmly against the ground.

[0027] Reference Figures 10-12, the support and defense unit 26 includes a support platform 261. On one side of the inner wall surface of the support platform 261, a carrier 263 is embedded. On the other side of the support platform 261, a rotating platform 2611 is fixedly connected. A rotating column 2612 passes through the center of the rotating platform 2611. The rotating platform 2611 is rotationally connected to the movable platform 24 via the rotating column 2612. When changing the inclination angle of the support platform 261, rotating the support platform 261 pulls the rotating platform 2611 and the rotating column 2612 to rotate on one side of the movable platform 24, enabling the extension block 264 and the support platform 261 to perform self-adjustment according to the ground inclination angle, thereby enhancing the stability of the support.

[0028] A rotating disk 262 is clamped in the carrier 263. At the top and bottom of the rotating disk 262, extension blocks 264 are respectively installed. On the opposite wall surfaces of the pair of extension blocks 264, a plurality of engaging blocks 265 are staggeredly installed. The engaging blocks 265 are engaged and connected to the teeth on the rotating disk 262. Pull one of the extension blocks 264 inside the support platform 261, so that the engaging blocks 265 inside the extension block 264 pull the rotating disk 262 to rotate. The engaging blocks 265 inside the other extension block 264 are also engaged with the teeth on the rotating disk 262, facilitating the simultaneous expansion of the pair of extension blocks 264 from inside the support platform 261.

[0029] On the other side of the extension block 264 farther from the rotating disk 262, a changing piece 266 is fixedly connected. A slideway 2613 is reserved on the inner surface of the support platform 261 at the position of the changing piece 266. The cross-section of the changing piece 266 is in an "丄" shape structure and can be movably installed in the slideway 2613. On the other side of the changing piece 266 farther from the extension block 264, a blocking piece 267 is fixedly connected. A passage 268 is reserved on the outside of the support platform 261 at the position of the blocking piece 267. The blocking piece 267 can be movably inserted through the passage 268; A plurality of protrusions 269 are respectively installed on the same side of the support platform 261 and the pair of extension blocks 264.

[0030] During the change of the extension block 264, it pulls the changing piece 266 to change in the slideway 2613, achieving the guiding of the extension block 264 and enhancing the stability of the lateral change of the extension block 264; The blocking piece 267 on the changing piece 266 changes in the passage 268, and the blocking piece 267 is restricted via the passage 268 to prevent the extension block 264 from pulling the changing piece 266 away from the support platform 261. When the pair of extension blocks 264 are fully expanded, the protrusions 269 on the same side of the extension block 264 and the support platform 261 are in contact with the ground, achieving the purpose of anti-sliding.

[0031] In operation, when the equipment is transferred, the support platform 11 is pulled by the handle on one side of the frame 12, so that the support platform 11 pulls the wheel hub 13 at the lower end of the frame 12 to move on the ground, so as to transfer the equipment. When the frame 12 and the support platform 11 are bumpy due to the road conditions during the equipment transfer, the bumpy action is transferred to the cover 8 through the concave platform 14 and the support seat 10. The cover 8 is pulled by the two pairs of connecting rods 17 to move the moving block 16 downward. When the moving block 16 moves downward in the trench 15, it presses the two pairs of movable tubes 181 and the two pairs of spiral beryllium copper wires 182. After the spiral beryllium copper wires 182 are pressed, they provide upward support for the moving block 16, reducing the bumpy action on the moving block 16 and the support seat 10, thereby reducing the bumps borne by the cover 8, and constraining the moving block 16 through the trench 15, enhancing the stability of the moving block 16 pulling the movable tube 181 to extend or shorten. During the compression of the movable tube 181, the air inside the movable tube 181 is transported to the silicone shell 184 through the channel 183. The silicone shell 184 expands to support the lower end of the support seat 10, thereby reducing the shaking between the support seat 10 and the cover 8 and preventing the cover 8 from moving back and forth vertically. This enhances the shock reduction effect of the equipment and ensures the safe transfer of the equipment. It also assists in the arrangement of several silicone protrusions 185 on the upper end of the silicone shell 184 to prevent the lower end of the support seat 10 and the silicone shell 184 from sliding sideways and causing unstable support. When the equipment moves upward under the support, the deformation of the spiral beryllium copper wire 182 supports the moving block 16, allowing the movable tube 181 to extend. Some air inside the silicone shell 184 returns to the movable tube 181 through the channel 183, thus achieving the effect of stable support for the equipment. When supporting and protecting the equipment, the pull block 211 is dragged by the handle 212, causing the pull block 211 to pull the movable platform 20 to move within the movable port 19. The movable platform 20 is constrained through the movable port 19, assisting the pull block 211 in pulling a pair of constraint posts 213 within the holes of the support platform 11, enhancing the smoothness of the movable platform 20's movement of the movable platform 24. After the movable platform 20 pulls the movable platform 24 out of the movable port 19, the movable platform 24, under its own weight, rotates around the pin in the U-shaped opening 25 until the support and protection unit 26 on one side of the movable platform 24 contacts the ground. As the support and protection unit 26 extends, an extension block 264 is dragged within the support platform 261, causing the interlocking blocks within the extension block 264 to engage. 265 pulls the rotating disk 262 to rotate, and the biting block 265 inside another extension block 264 also bites and connects with the rotating disk 262, allowing a pair of extension blocks 264 to extend from both sides inside the support platform 261. During the movement of the extension block 264, the moving plate 266 moves in the slide 2613, thereby guiding the extension block 264 and enhancing the stability of the lateral movement of the extension block 264. The blocking plate 267 on the moving plate 266 moves in the passage 268, and the blocking plate 267 is constrained through the passage 268 to prevent the extension block 264 from pulling the moving plate 266 away from the support platform 261. When a pair of extension blocks 264 are fully extended, the protrusion 269 on the same side of the extension block 264 and the support platform 261 is in contact with the ground surface, achieving the purpose of anti-slip. When the tilt angle of the support platform 261 is changed, the rotation of the support platform 261 pulls the rotating platform 2611 and the rotating column 2612 to rotate on one side of the movable platform 24, so that the extension block 264 and the support platform 261 perform self-adjustment according to the ground tilt angle, thereby enhancing the stability of the support. At this time, the insertion interface 22 on the variable platform 20 is at the bottom of the lead screw 233. The lead screw 233 is pulled to rotate in the threaded cylinder 232 by rotating the handle 234, so that the lead screw 233 moves downward and passes through the insertion interface 22, thereby stopping the variable platform 20 to prevent the variable platform 20 from moving on its own in the variable port 19. The lower end of the lead screw 233 is arched. During the downward movement of the lead screw 233, it presses the upper end of the movable platform 24. When the movable platform 24 is pressed, it presses the support platform 261 at the lower end, so that the support platform 261 and a pair of extension blocks 264 are pressed tightly to the ground, thereby achieving the purpose of strengthening the support of the equipment. When releasing the support of the equipment, rotate the handle 234 in the reverse direction, causing the handle 234 to pull the lead screw 233 upwards during rotation, until the lower end of the lead screw 233 moves away from the engagement interface 22 on the moving platform 20. At this point, the moving platform 20 is in a self-moving state. Then, press the extension block 264 on one side of the support platform 261. The extension block 264 pulls the rotating disk 262 to rotate through the biting block 265, and the extension block 264 on the other side can move together, allowing the pair of extension blocks 264 to move together into the support platform 261, and then grab... Press the handle 212 to pull the drag block 211, causing the drag block 211 to pull the movable platform 20 toward the movable opening 19. During the movement of the movable platform 20 pulling the movable platform 24, the movable platform 24 is supported at the opening of the movable opening 19 and twists until the movable platform 24 pulls the support platform 261 into the U-shaped opening 25 at the bottom of the movable platform 20. Then press the drag block 211, causing the drag block 211 to pull the movable platform 20 and the support and defense unit 26 to move into the movable opening 19 and be retracted, thus canceling the support of the equipment.
