Abstract
Description
Technical Field
[0001] This invention relates to the field of emergency care technology, and in particular to a device for loading and unloading a vehicle-mounted CT scanner and a hyperbaric oxygen chamber in an ambulance. Background Technology
[0002] Cerebral stroke, also known as stroke or cerebrovascular accident (CVA), is an acute cerebrovascular disease. It is a group of diseases caused by the sudden rupture of blood vessels in the brain or by the blockage of blood vessels, which prevents blood from flowing into the brain and causes damage to brain tissue. It includes ischemic stroke and hemorrhagic stroke.
[0003] Ischemic stroke has a higher incidence than hemorrhagic stroke, accounting for 60%–70% of all strokes. Occlusion and stenosis of the internal carotid artery and vertebral artery can cause ischemic stroke, primarily affecting individuals over 40 years of age, and is more common in men than women; severe cases can lead to death. Hemorrhagic stroke has a higher mortality rate.
[0004] The key to stroke emergency care is to first use a CT scanner (computed tomography) to determine the type of stroke. Therefore, bringing the CT scanner to the patient as soon as possible will buy the patient golden time for rescue.
[0005] Mobile CT scanners already exist in the technology, equipped with casters for easy movement, and can be carried by ambulances to complete the diagnosis of patients before admission;
[0006] However, in actual use, in addition to being placed inside the ambulance, the mobile CT scanner is also pushed into the hospital department when needed, so loading and unloading the CT scanner on the ambulance has become a problem;
[0007] Mobile CT scanners are large in size and generally weigh more than 250 kilograms. Manual handling is time-consuming and labor-intensive, and the safety of the equipment cannot be guaranteed during the handling process.
[0008] Hyperbaric oxygen chambers are specialized medical equipment for hyperbaric oxygen therapy. Traditional hyperbaric oxygen chambers are large and inconvenient to move, so they are mostly placed in hospitals. In case of emergency, patients often need to be taken to the hospital by ambulance before treatment can be given, which may result in untimely and ineffective treatment and thus affect the patient's cure rate.
[0009] Installing a hyperbaric oxygen chamber in an ambulance could provide more timely treatment for specific patients. However, in addition to being placed inside the ambulance, it would also be pushed into hospital departments when needed. Therefore, loading and unloading the hyperbaric oxygen chamber in an ambulance becomes a problem.
[0010] Therefore, a device is needed that allows for the installation and removal of a mobile CT scanner and hyperbaric oxygen chamber on an ambulance at any time. Summary of the Invention

One end of chain seven 594 is installed on sprocket eight 571 and the other end is installed on a set of sprockets twelve 578 of the side chain rod 577. One end of chain eight 595 is installed on sprocket ten 573 and the other end is installed on another set of sprockets twelve 578 of the side chain rod 577.
[0073] like Figure 9 As shown, the movable plate 60 has two sets of stretching plates 61, and each set of stretching plates 61 is connected to a roll of cloth 58.
[0074] The basic principle of this invention:
[0075] like Figure 3 , Figure 7 As shown, this is the initial state of the present invention. The two sets of hydraulic rods 281 are retracted into the hydraulic cylinder 14, the slide base 30 is located in the slide rail 13, the slide plate 40 is located in the groove 32, the rear side of the slide plate 40 is attached to the rear side of the groove 32, and both sets of doors 25 are in the closed state.
[0076] Then, the medical staff pushed the mobile CT scanner and the mobile hyperbaric oxygen chamber onto the two sets of mobile plates 60 respectively. Then, the hydraulic cylinder 14 pushed the two sets of hydraulic rods 281 to move, which in turn pushed the push plate 28 to move. The push plate 28 pushed the two sets of push rods 282, clamping plate 283, and lead screw 284 to move synchronously. The clamping plate 283 will press the spring 29 until the elastic force of the spring 29 is balanced with the dynamic friction force of the sliding plate base 30. The sliding plate base 30 will move, which will then move the sliding plate 40 together. The sliding plate 40 will move until the transmission gear 36 meshes with the rack 151, which will cause the transmission gear 36 to rotate. This will cause the rack 311 to drive the sliding plate 40 to move until the sliding plate base 30 contacts the base plate 10.
[0077] Then the motor 322 starts to drive the spline shaft 323 to rotate, so that the main drive shaft 56 rotates through the spline hole 564 and the spline shaft 323, thereby moving the two sets of moving plates 60 completely outside the ambulance.
[0078] During this process, the two sets of lead screws 284 in the direction of each set of moving plates 60 will move through the two sets of springs 29 to the middle section of the threaded holes 265 of the two sets of threaded drive shafts 26, causing the two sets of threaded drive shafts 26 to rotate, which in turn causes the two sets of sprockets 263 to rotate. This, in turn, causes the two sets of sprockets 241 to rotate through chains 27 and 271, which in turn causes the two sets of short gear shafts 24 to drive gear 242 to rotate, which in turn causes rack 252 to move the door 25 upward a certain distance. At this time, the state of the present invention is as follows. Figure 4 , Figure 8 As shown;
[0079] Then, hydraulic cylinder 14 continues to push the two sets of hydraulic rods 281 to move, which in turn causes the two sets of push plates 28 to continue pushing the two sets of push rods 282, clamping plates 283, and lead screws 284 to move synchronously. Clamping plates 283 will compress spring 29 to its limit, causing lead screws 284 to continue moving, thereby causing the two sets of threaded drive shafts 26 to continue rotating, and thus causing door 25 to continue moving upward until... Figure 5 , Figure 9 The state shown;
[0080] Then, motor 322 starts and drives spline shaft 323 to rotate. Spline shaft 323 drives main drive shaft 56 to rotate through spline hole 564. Main drive shaft 56 drives gear 3 552 to rotate through gear 4 561. Sprocket 7 562 drives a set of sprockets 3 51 to rotate through chain 4 591. Sprocket 6 553 drives another set of sprockets 3 51 to rotate through chain 3 59. Sprockets 4 52 and sprocket 53 of the two sets of long sprocket rods 50 will cause two sets of sprockets 9 572 and sprocket 11 574 to rotate through chains 5 592 and 6 593, thereby causing short sprocket rod 57 to rotate, and then causing sprockets 8 571 and sprocket 10 573 to rotate. Through chains 7 594 and 8 595, the two sets of sprockets 12 578 of each set of side sprocket rods 577 rotate, thereby releasing the rolled fabric 58. The moving plate 60 moves downward through the stretching plate 61. At this time, the state of the present invention is as follows. Figure 6 , Figure 10 As shown, the medical staff then unloaded the mobile CT scanner and the mobile hyperbaric oxygen chamber from the two sets of mobile panels 60 respectively.
[0081] Then, the motor 322 of the present invention reverses, causing the two sets of moving plates 60 to retract. Then, the hydraulic cylinder 14 retracts the two sets of hydraulic rods 281, thereby causing the push plate 28 to retract. This causes the push rod 282 to move the locking plate 283, thereby releasing the spring 29. Then, the locking plate 283, through the locking slot 351, drives the slide plate base 30 back to its original position, thus returning the present invention to its original state. Figure 1 The state shown.
