Description

Technical Field

[0001] The present application relates to the field of CT technology, and in particular to a CT vehicle. Background Art

[0002] Currently, CT machines are computer-assisted imaging devices that use X-rays as the transmission energy for human body tomographic scanning. They have become a popular medical device for examination and diagnosis in hospitals. CT examinations are significantly superior to X-rays in displaying cross-sections and can provide the most valuable guiding information for surgical operations in emergency treatment.

[0003] Most existing CT machines are installed inside hospitals. If a patient needs to be examined, he or she needs to travel a long distance to the hospital for examination. The inventor believes that it is very inconvenient for patients to undergo a CT examination. Summary of the Invention

[0004] In order to facilitate examinations for patients and provide more convenience for patients, the present application provides a CT vehicle.

[0005] The CT vehicle provided in this application adopts the following technical solution:

[0006] A CT vehicle comprises a trailer provided with a carriage, wherein a CT machine is provided inside the carriage, a scanning cavity is provided on the CT machine, the axis direction of the scanning cavity is the same as the width direction of the carriage, a CT scanning bed used in conjunction with the CT machine is provided on one side, and a support assembly for supporting the CT scanning bed is provided inside the carriage.

[0007] By adopting the above technical solution, when a patient needs a CT examination, he or she can call a CT vehicle, which can transport the CT machine and the CT scanning bed to the patient's residence, thereby providing more convenience for the patient and facilitating the examination of the patient.

[0008] Preferably, an expansion cabin capable of sliding along the axis of the scanning cavity is provided on the side of the carriage facing the scanning cavity, and the CT scanning bed is located inside the expansion cabin and can rotate around a vertical axis on the support assembly.

[0009] By adopting the above technical solution, before examining the patient inside the carriage, the length direction of the CT scanning bed can be made parallel to the length direction of the carriage, which can reduce the width requirement of the CT machine for the CT cart; during the examination, the expansion cabin can be slid along the axis direction of the scanning cavity away from the carriage, and the expansion cabin will drive the CT scanning bed to move away from the CT machine, and then drive the CT scanning bed to rotate around a vertical axis on the support assembly until the length direction of the CT scanning bed is the same as the axis direction of the scanning cavity, and then the patient examination can be started.

[0010] Preferably, the support assembly includes a fixed seat, on which a horizontal turntable is provided that can drive the CT scanning bed to rotate around its own axis.

[0011] By adopting the above technical solution, when the CT scanning bed needs to be driven to rotate inside the carriage, the turntable can be driven to rotate on the fixed seat.

[0012] Preferably, four balancing legs with the same structure that can drive the trailer to move back and forth in the vertical direction are provided under the trailer, and a detection system for detecting the pressure on the balancing legs is coupled to the balancing legs.

[0013] By adopting the above technical solution, the weight of the CT vehicle is a fixed value. When the CT vehicle maintains balance, the balancing legs are used to drive the trailer to move upward until it leaves the ground. The pressure on the balancing legs is a fixed value and the pressure on the four balancing legs should be approximately the same. Therefore, when the CT vehicle is used to examine people, the pressure on each balancing leg is detected by the detection system. This can determine whether the CT vehicle is in a balanced state, thereby improving the accuracy of the CT machine in detecting people's conditions.

[0014] Preferably, a fixing device for positioning the CT machine is provided inside the carriage, including two protective layers arranged on both sides of the CT machine and abutting against the sides of the CT machine, and the two opposite ends of each protective layer are detachably connected to a fixing ring fixedly connected to the inner wall of the carriage.

[0015] By adopting the above technical solution, when the CT machine is transported by a trailer, two layers of protective nets are placed on both sides of the CT machine and are in contact with the sides of the CT machine. Then, the ends of each layer of protective nets are fixed to the fixing rings. The protective nets can reduce the possibility of the CT machine tipping over inside the vehicle and thus being damaged. After the CT machine is transported to the designated location by the trailer, the protective layers and the fixing rings can be separated from each other.

[0016] Preferably, the fixing rings at both ends of each protective layer are located on the top and bottom surfaces of the vehicle compartment.

[0017] By adopting the above technical solution, the fixing rings are located on the top and bottom surfaces of the carriage, which can make the protective layer more effective in protecting the CT machine.

[0018] Preferably, the protective layer includes a protective net, a connecting strip is connected to the bottom of the protective net, and hooks detachably connected to the fixing ring are provided at the upper end of the protective net and the lower end of the connecting strip.

[0019] By adopting the above technical solution, after the CT machine is transported to the designated location, the protective net and the hooks on the connecting bar can be separated from the fixing rings.

[0020] Preferably, a manhole is provided on the carriage, a sealed door is installed inside the manhole, and a ladder is provided below the sealed door, which is inclined downward from close to away from the carriage.

[0021] By adopting the above technical solution, when it is necessary to enter the interior of the carriage, the sealed door is opened and the ladder outside the carriage can facilitate people to enter the carriage.

[0022] Preferably, a receiving groove for a ladder to enter is provided below the manhole, a mounting rod is slidably connected inside the receiving groove, and the mounting rod is hinged to the end of the ladder near the end of the ladder around a horizontal axis.

[0023] By adopting the above technical solution, after the ladder is used, the ladder is rotated on the mounting rod, and then the mounting rod and the ladder are moved toward the interior of the carriage, so that the ladder can be stored in the accommodating groove.

[0024] Preferably, a storage box is provided on the outside of the carriage, and a sunshade cloth that can be pulled out to cover the manhole or expansion cabin is provided inside the storage box.

[0025] By adopting the above technical solution, when the CT vehicle is in use, it is necessary to maintain a certain temperature inside the vehicle compartment. At this time, the sunshade cloth can be pulled out from the inside of the storage box. The sunshade cloth can prevent the manhole or expansion cabin from being directly exposed to sunlight, thereby reducing the impact of external light on the temperature or humidity inside the vehicle compartment.

[0034] The present application is further described in detail below with reference to the accompanying drawings.

[0035] Reference Figure 1 and Figure 2 The present application provides a CT vehicle, comprising a trailer 1, a CT machine 2, a CT scanning bed 3, and a support assembly 4. The trailer 1 is provided with a carriage 11, the side panels of the carriage 11 being made of lead plates, and adjacent side panels being overlapped with each other, thereby reducing the radiation from the CT machine 2 to the outside of the carriage 11. The CT machine 2 and the CT scanning bed 3 are both arranged inside the carriage 11. The CT machine 2 is provided with a scanning cavity 21, the central axis of which is horizontal and in the same direction as the width of the carriage 11. The CT scanning bed 3 is made of carbon fiber, is located on one side of the CT machine 2, and when in use, its extension direction is in the same direction as the axis of the scanning cavity 21. The support assembly 4 is arranged between the CT scanning bed 3 and the carriage 11 to support the CT scanning bed 3. When people need to be examined, they lie flat on the CT scanning bed 3, and the CT machine 2 can perform CT examinations on them.

[0036] Reference Figure 3 and Figure 4The support assembly 4 includes a fixing seat 41, a guide rail 42 and a fixing block 43. The fixing seat 41 is arranged on the lower surface of the carriage 11, and the fixing block 43 is arranged above the fixing seat 41; the guide rail 42 is made of carbon fiber, and the length direction of the guide rail 42 is the same as the length direction of the CT scanning bed 3. The guide rail 42 is arranged on the lower surface of the CT scanning bed 3 and is detachably fixed to the CT scanning bed 3 by installing bolts 44. The guide rail 42 passes through the fixing block 43 and is slidably connected to the fixing block 43. The tightening bolt 45 is arranged on one side of the fixing block 43, and the tightening bolt 45 extends to the inside of the fixing block 43 in the direction close to the fixing block 43 and presses against the guide rail 42.

[0037] After people lie on the CT scanning bed 3, if they need to move closer to or away from the CT machine 2, they first loosen the tightening bolts 45 and push the CT scanning bed 3. The CT scanning bed 3 will drive the guide rail 42 to slide on the fixed block 43. After the CT scanning bed 3 is moved to the specified position, the tightening bolts 45 are tightened. The tightening bolts 45 press against the guide rail 42 to limit the guide rail 42 and the CT scanning bed 3. After the CT scanning bed 3 has been used for a period of time, the guide rail 42 will be worn. The guide rail 42 can be detachably installed on the CT scanning bed 3 by installing bolts 44, which makes it convenient for people to replace the guide rail 42.

[0038] Reference Figure 4 In order to facilitate people to rotate the tightening bolt 45 on the fixing block 43, a locking handle 46 is provided on the end of the tightening bolt 45 away from the fixing block 43.

[0039] Reference Figure 2 and Figure 5 The carriage 11 is provided with an expansion cabin 12 on the side opposite to the scanning cavity 21. The carriage 11 is provided with a pusher 13 for driving the expansion cabin 12 to move back and forth along the axis direction of the scanning cavity 21. The fixing seat 41 is provided inside the expansion cabin 12. Figure 3 A fixing bracket 47 is provided on the fixing seat 41, a turntable 48 is fixed to the fixing bracket 47, and a connecting plate 49 that can rotate about a vertical axis is fixed to the turntable 48. The upper surface of the connecting plate 49 and the fixing block 43 are detachably mounted on the connecting plate 49 via fixing bolts. When the CT machine 2 inside the carriage 11 is transported using the trailer 1, the turntable 48 first drives the connecting plate 49 and the CT scanning bed 3 to rotate together about a vertical axis until the CT scanning bed 3 is completely located inside the expansion cabin 12; then, the pusher 13 drives the expansion cabin 12 to move closer to the interior of the carriage 11. This reduces the width of the carriage 11 and facilitates the transportation of the CT machine 2.

[0040] Reference Figure 5The pushing member 13 includes a pushing cylinder 131 and guide rods 132 arranged on both sides of the pushing cylinder 131. A card plate 121 with a cross-sectional area larger than that of the expansion cabin 12 is provided on the end surface of the expansion cabin 12 away from the car body 11. The pushing cylinder 131 is fixed inside the car body 11. The piston rod of the pushing cylinder 131 is fixedly connected to the side of the card plate 121 close to the car body 11. The extension direction of the guide rod 132 is parallel to the movement direction of the expansion cabin 12. The end of the guide rod 132 close to the car body 11 is inserted into the car body 11 and is slidably connected to the car body 11. The end away from the car body 11 is fixedly connected to the card plate 121. When the pushing cylinder 131 drives the piston rod to move, it will drive the expansion cabin 12 to slide in and out on the car body 11 through the card plate 121. The guide rod 132 has a guiding effect on the movement process of the car body 11, which can make the movement process of the car body 11 more stable.

[0041] Reference Figure 4 To adapt the CT scanner bed 3 to a wider range of patient heights, a movable frame 411 is positioned above the fixed base 41. A lifting member 412 is positioned between the fixed base 41 and the movable frame 411 to move the movable frame 411 vertically up and down. In this embodiment, the lifting member 412 is a three-stage lifting cylinder. In other embodiments, the lifting member 412 may also utilize other lifting structures with the same effect. As the patient's height changes, the lifting member 412 can drive the movable frame 411, the fixed frame 47, and the structure above the fixed frame 47, including the CT scanner bed 3, to move vertically up and down, making it easier for the patient to lie on the CT scanner bed 3.

[0042] Reference Figure 2 The trailer 1 may shake when transporting the CT machine 2 inside the carriage 11. In order to reduce the possibility of damage to the CT machine 2 caused by shaking, a fixing device 5 for positioning the CT machine 2 is provided inside the carriage 11.

[0043] Reference Figure 6The fixing device 5 includes a mounting plate 51, a fixing ring 52, and a protective layer. The mounting plate 51 is horizontally positioned below the CT scanner 2. The protective layer comprises two layers, each of which is vertically positioned on either side of the CT scanner 2. Each layer of the protective layer corresponds to two sets of fixing rings 52, each of which is provided with a stud. The two sets of fixing rings 52 are threadedly mounted on the top surface of the interior of the carriage 11 and the upper surface of the mounting plate 51 via the studs, and are detachably connected to the upper and lower end surfaces of the protective layer. When the trailer 1 is required to transport the CT scanner 2 within the carriage 11, the two protective layers are placed on either side of the CT scanner 2, abutting the sides of the CT scanner 2. The upper and lower end surfaces of the protective layers are then connected to the fixing rings 52 on either side. If the CT scanner 2 tends to shake, the two protective layers can reduce the shaking tendency of the CT scanner 2, thereby reducing the possibility of damage to the CT scanner 2.

[0044] Reference Figure 6 The protective layer includes a protective net 531, a connecting bar 532 and a hook 533. The protective net 531 is located above the connecting bar 532. There are two groups of hooks 533, and the two groups of hooks 533 are respectively arranged on the side away from each other of the connecting bar 532 and the protective net 531; the protective net 531 includes longitudinal bars 534 and transverse bars 535 that are cross-connected and fixed to each other. The upper end of the longitudinal bar 534 is fixedly connected to the hook 533, and a rope tightener 536 is provided between the lower end of the longitudinal bar 534 and the connecting bar 532; an auxiliary bar 537 is provided between the two protective layers, and both ends of the auxiliary bar 537 are fixedly connected to the transverse bar 535 inside the protective net 531.

[0045] When the protective layer needs to be installed on the fixing ring 52, the hooks 533 on the longitudinal bars 534 and the connecting bars 532 are hung on the fixing ring 52. The tension between the longitudinal bars 534 and the connecting bars 532 can be adjusted by the rope tightener 536, so that the protective layer can protect the CT machine 2 more effectively; the auxiliary bar 537 between the two protective layers can enhance the integrity of the two protective layers and reduce the possibility of damage to the protective layers due to the stress on one protective layer alone.

[0046] Reference Figure 5 When using the CT machine 2 to perform CT examinations on people, it is necessary to ensure that the CT machine 2 is in a balanced state. In order to improve the accuracy of the examination results of the CT machine 2 on people, four balancing legs 6 with the same structure are provided under the carriage 11 and can drive the trailer 1 to move back and forth in the vertical direction. The balancing legs 6 are coupled to a detection system for detecting the pressure on the balancing legs 6.

[0047] The weight of the CT vehicle is a fixed value. When the CT vehicle maintains balance, the balancing legs 6 are used to drive the trailer 1 to move upward until it leaves the ground. The pressure on the balancing legs 6 is a fixed value and the pressure on the four balancing legs 6 should be approximately the same. Therefore, when the CT vehicle is used to examine people, the pressure on each balancing leg 6 is detected by the detection system. This can determine whether the CT vehicle is in a balanced state, thereby improving the accuracy of the CT machine 2 in detecting people's conditions.

[0048] Reference Figure 5 In this embodiment, the balancing leg 6 can be a hydraulic cylinder, and the cylinder body of the hydraulic cylinder is fixedly connected to the car body 11. The piston rod of the hydraulic rod extends downward in the vertical direction and is coaxially fixed with a support 64. The cross-sectional area of ​​the support 64 is larger than the cross-sectional area of ​​the piston rod of the hydraulic cylinder. Other balancing legs 6 with the same effect are still applicable.

[0049] Reference Figure 7 The detection system includes a detection component 61, a control component 62, and a display component 63. The detection component 61 is a pressure sensor provided on the balancing leg 6 for detecting the pressure on the balancing leg 6. The control component 62 is a single-chip microcomputer provided inside the car body 11 and coupled to the detection component 61. The display component 63 is a display screen provided inside the car body 11 and coupled to the control component 62. After the car body 11 leaves the ground, the pressure on the balancing leg 6 is detected by the detection component 61. The pressure on the balancing leg 6 can be displayed on the display screen in the form of data. People can judge whether the car body 11 is in a balanced state based on the data on the display screen. If the balanced state is not reached, the balanced state of the car body 11 can be adjusted by moving the trailer 1 to change the position of the trailer 1 until the pressure areas on the four balancing legs 6 are the same.

[0050] Reference Figure 1 and Figure 2, an equipment hole 14 is provided on the side of the carriage 11 away from the front of the trailer 1, and two door panels 15 with the same structure are rotatably connected inside the equipment hole 14 for opening or closing the equipment hole 14. A manhole 16 is also provided on the carriage 11, and the manhole 16 is located on the side of the expansion cabin 12 away from the front of the trailer 1. A sealed door 17 is hinged inside the manhole 16 to open or close the manhole 16. A ladder 18 is provided below the manhole 16 to facilitate people entering and exiting the carriage 11. The ladder 18 gradually tilts towards the ground from approaching to away from the carriage 11; a position on the side of the carriage 11 that is directly opposite to the upper end of the ladder 18 is opened. A accommodating groove 111 is provided, and a mounting rod 112 is provided inside the accommodating groove 111. The mounting block and the carriage 11 can slide inside the accommodating groove 111 by cooperating with the slider and the slide groove. The end of the mounting rod 112 close to the ladder 18 is hinged to the upper end of the ladder 18 around a horizontal axis. After the ladder 18 is used, people can rotate the ladder 18 on the mounting rod 112 until the ladder 18 is in a horizontal state, and then move the ladder 18 toward the carriage 11. The ladder 18 will drive the mounting rod 112 to move toward the inside of the carriage 11, so that the ladder 18 can be stored inside the accommodating groove 111.

[0051] Reference Figure 1 Two storage boxes 7 are provided on the outside of the carriage 11. The two storage boxes 7 are respectively located above the expansion cabin 12 and the sealing door 17. A winding shaft 71 is provided inside the storage box 7. A rolled sunshade cloth 73 is provided on the winding shaft 71. The movable end of the sunshade cloth 73 is located on the outside of the storage box 7. A through hole is opened on the storage box 7 for the sunshade cloth 73 to pass through. A rotating motor 74 is provided on the carriage 11 to drive the winding shaft 71 to rotate inside the storage box 7.

[0052] When the sealing door 17 is opened or the expansion cabin 12 is pulled out from the interior of the carriage 11, the winding shaft 71 is driven to rotate by rotating the motor 74, and the winding shaft 71 unwinds the sunshade cloth 73, and then the sunshade cloth 73 passes from the side of the sealing door 17 or the card plate 121 away from the carriage 11, so that the sunshade cloth 73 can prevent the manhole 16 or the expansion cabin 12 from being directly exposed to the sun, reducing the impact of the external environment on the temperature and humidity inside the carriage 11.

[0053] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
