Description

Technical Field

[0001] The present invention relates to the technical field of emergency care, and in particular to a device for loading and unloading a vehicle-mounted CT machine on an ambulance. Background Art

[0002] Stroke, the medical term for it is "cerebrovascular accident" and commonly referred to as "stroke", is a serious medical condition. It refers to the sudden rupture or blockage of blood vessels in the brain, which prevents blood from flowing normally to the brain, causing damage to brain tissue. This damage may be due to ischemia caused by blood vessel blockage or bleeding caused by blood vessel rupture, both of which may cause acute effects on brain function. Stroke is a disease that requires urgent medical intervention because it can quickly lead to the loss of partial or total body function, or even death. It is characterized by high morbidity, high disability rate, high mortality rate and high recurrence rate.

[0003] The key to emergency treatment of stroke is to first use a CT machine (computed tomography) to determine the type of stroke. Therefore, bringing the CT machine to the patient as soon as possible will buy golden time for the patient's rescue.

[0070] Basic principles of the present invention:

[0071] like Figure 1 As shown, this is the initial state of the present invention, where multiple groups of connecting bars 31 are evenly arranged. When the mobile CT machine needs to be moved out of the ambulance, the medical staff moves the connecting bars 31 to the positions shown in FIG. Figure 2 、 Figure 3 Then, the mobile CT machine is pushed onto the mobile plate 30, and the plurality of connecting strips 31 are restored to the state shown. Figure 1 In the state shown, the semicircular bottom plate 22 is lifted and supported;

[0072] Then the motor 16 starts to drive the central shaft 201 to rotate, thereby rotating the rotating plate 20 by 180 degrees, and then the hydraulic cylinder 1 50 drives the hydraulic rod 1 52 to move, thereby causing the hydraulic rod 1 52 to drive the horizontal plate 53 to move, thereby causing the horizontal plate 53 to drive the two groups of hydraulic cylinders 2 54 to move, and the two groups of hydraulic cylinders 2 54 slide in the two groups of slideways 1 141 through the side slides 541. At this time, the state of the present invention is as follows: Figure 4 As shown;

[0073] Then the two groups of hydraulic cylinders 2 54 drive the hydraulic rods 2 55 and 3 56 to move into the two groups of slideways 2 24. At this time, the state of the present invention is as follows: Figure 5 As shown, the hydraulic rod 2 55 and the hydraulic rod 3 56 continue to move and slide out from the two sets of slideway openings 243. At this time, the state of the present invention is as follows: Figure 6 As shown;

[0074] exist Figures 4 to 6 During the process, the movement of the second hydraulic rod 55 and the third hydraulic rod 56 will drive the first vertical slide 551 and the second vertical slide 562 to slide synchronously in the two sets of slideways 24. During the sliding process, the second rack 553 and the fourth rack 563 will first engage with the two sets of gears 43, thereby rotating the gear 43, thereby driving the sprocket 431 to rotate. The sprocket 431 drives the sprocket 3 41 to rotate through the second chain 42, thereby causing the two sets of support plates 40 to rotate around the sixth rotating shaft 411 of the rotating part 401 as the axis. After breaking free from the suction of the magnet 251, they rotate downward perpendicular to the ground to support the semicircular bottom plate 22.

[0075] Then the hydraulic rod 2 55 and the hydraulic rod 3 56 continue to move, so that the rack 2 553 and the rack 4 563 are out of mesh with the gear 4 43, and the rack 1 552 and the rack 3 561 are meshed with the gear 1 32, so that the gear 1 32 rotates, and then the bevel gear 1 322 rotates, and then the bevel gear 2 331 rotates, and then the rotating shaft 2 33 drives the bevel gear 3 332 and the sprocket 1 333 to rotate synchronously, and the sprocket 1 333 drives the sprocket 2 341 to rotate through the chain 1 35, so that ... The third shaft 34 rotates synchronously with the second rotating shaft 33, thereby causing the fourth bevel gear 342 and the third bevel gear 332 to rotate synchronously. The fourth bevel gear 342 and the third bevel gear 332 drive the fourth rotating shaft 36 to rotate by cooperating with the fifth bevel gear 361, thereby causing the second gear 362 to rotate. The second gear 362 rotates the fifth rotating shaft 37 by cooperating with the third gear 371. The fifth rotating shaft 37 cooperates with the left-hand screw 301 and the right-hand screw 302 through the threaded hole 372 to cause the movable plate 30 to descend.

[0076] The medical staff then moves the connecting strip 31 to the position as shown in FIG.
