[0018] In order to enable the infusion rod 4 to move up and down, an empty slot with an opening facing forward is opened on the right side of the main body 1, and the rear side of the empty slot is connected to the vertical slot. A rotating shaft 7 with a left and right axial direction is rotatably connected in the empty slot, and a lever 8 in the front and back directions is fixed on the rotating shaft 7. An arc-shaped rack 9 is fixed to the rear end of the lever 8. A plurality of third tooth grooves 10 distributed in the up and down directions are opened on the front side of the infusion rod 4. A power gear 11 with a left and right axial direction and meshing with the third tooth groove 10 is rotatably connected in the empty slot. An intermediate gear 12 is rotatably connected in the empty slot. The front side of the intermediate gear 12 is meshed with the arc-shaped rack 9 and the rear side is meshed with the power gear 11.

[0019] In order to make the front end of the lever 8 swing downward by a small amplitude and the rear end thereof swing by a larger amplitude, that is, to facilitate smooth reset of the lever 8, the distance between the front end of the lever 8 and the rotating shaft 7 is smaller than the distance between the rear end thereof and the rotating shaft 7, and the left and right sides of the rotating shaft 7 are respectively connected to the main body 1 via coil springs 13.

[0020] In order to limit the position of the extension plate 2 and the infusion pole 4 after they are deployed, an arc-shaped groove is opened on the right side wall of the main body 1, which runs through the left and right sides and is coaxial with the rotating shaft 7. An arc-shaped rod 14 is slidably connected to the arc-shaped groove in the left and right directions. The right end of the arc-shaped rod 14 extends out of the main body 1 and is fixed with a baffle 15. The baffle 15 is connected to the right end surface of the main body 1 via a tension spring. The front side surface of the arc-shaped rod 14 is an inclined surface with the left end tilted backward.

[0021] The main body 1 is provided with a plurality of slide grooves distributed in the up and down directions and opening forward, a drawer 16 is slidably connected in the slide groove, an inverted earth-shaped partition is fixed in the drawer 16, the main body 1 is provided with a placement groove 17 located below the slide groove and opening forward, and the main body 1 is provided with a storage groove 18 located on the left side of the placement groove 17 and the front and left sides are respectively connected to the outside world.

[0022] In order to facilitate the storage of more items, a mesh storage bag is fixed to the right side of the main body 1, a bracket 19 with an upward opening is fixed to the left side of the main body 1, and a restraint belt 20 is fixed to the left side of the main body 1 above the bracket 19. The free end of the restraint belt 20 can be bonded to the rear end face of the main body 1 via Velcro.

[0023] In order to facilitate the movement of the main body 1, wheels with brake functions are fixed at the four corners of the lower end of the main body 1, and a handrail is fixed at the left end of the main body 1.

[0024] When the present invention is in use, the spaces in the multiple drawers 16 are respectively used to place connectors, needles and threads, injection supplies, informed consent forms, medicines, surgical gowns, gloves, guide wires, disinfectants and sterile sheets, etc., which are necessary for rescuing patients. The oxygen cylinder is placed in the holder 19, and the restraint belt 20 is passed around the outside of the oxygen cylinder and adhered to the rear side of the main body 1 through Velcro. The ECMO machine is placed in the storage slot 18, and the ultrasound machine and membrane lung supplies are placed in the placement slot 17. The infusion pole 4 and the extension plate 2 are both stored in the main body 1, the lever 8 is in a horizontal state, and the coil spring 13 and the tension spring are in their initial uncompressed state.

[0025] When ECPR is required for the patient, the medical staff pushes the armrest to push the main body 1 to the side of the bed, presses the front end of the lever 8 downward, and the front end of the lever 8 swings downward. At the same time, the lever 8 drives the rotating shaft 7 to rotate and compresses the coil spring 13. The rear end of the lever 8 drives the arc-shaped rack 9 to swing upward, and drives the intermediate gear 12 and the power gear 11 to rotate. The power gear 11 engages with the third tooth groove 10 to move the infusion pole 4 upward. At the same time, the second tooth groove 5 engages with the transmission gear 6 to rotate. The transmission gear 6 engages with the first tooth groove 3 to move the extension plate 2 to the right.

[0026] When the lever 8 swings downward and squeezes the inclined surface on the arc rod 14, the arc rod 14 drives the baffle 15 to move to the right and stretches the tension spring. When the front end of the lever 8 swings downward until it is out of contact with the arc rod 14, the arc rod 14 is reset to the left under the action of the tension spring and is located on the upper side of the front end of the lever 8. The medical staff stops pressing the front end of the lever 8 downward. The arc rod 14 blocks the front end of the lever 8 from swinging upward. At this time, the infusion pole 4 extends upward and the extension plate 2 extends to the right, increasing the operating area. The maximum height of the infusion pole 4 after extension is set within the height range prescribed by medicine. The medical staff will take out the corresponding items and machines according to the rescue needs of the patient and place them on the upper surface of the main body 1 and the extension plate 2 to perform the corresponding rescue operations.

[0027] After the patient's rescue is completed, the unused sterile items and machines are placed in the drawer 16, storage slot 18 or placement slot 17. After cleaning the items on the extension plate 2, pull the baffle 15 to the right. The baffle 15 drives the arc rod 14 to move to the right and stretches the tension spring. When the arc rod 14 is out of contact with the lever 8, the front end of the lever 8 swings upward under the action of the coil spring 13, and its rear end swings downward. Under the action of the intermediate gear 12 and the power gear 11, the infusion rod 4 moves downward into the vertical groove. At the same time, with the cooperation of the second tooth groove 5, the transmission gear 6 and the first tooth groove 3, the extension plate 2 moves to the left into the horizontal groove. When the coil spring 13 returns to its initial state, the infusion rod 4 and the extension plate 2 both return to their initial state, and the main body 1 can be pushed away.
