Description

Technical Field

[0001] This invention relates to the field of CT equipment maintenance, and more particularly to a CT equipment cleaning device. Background Technology

[0002] CT equipment, or "Computed Tomography," was developed by British physicists in 1971 and is now widely used in the field of clinical medicine. CT evolved from X-ray machines and has significantly improved the resolution of X-ray examinations. Its resolution and qualitative diagnostic accuracy are much higher than those of ordinary X-ray machines, thus broadening the scope of application of X-ray examinations and greatly improving the accuracy of X-ray diagnosis.

[0003] CT equipment mainly consists of a scanning bed, scanning gantry, high-voltage generator, computer system, and operating console. Because the scanning bed and the inner ring of the scanning gantry are in direct contact with the patient or are very close during examination, bodily fluids, splashed blood, and spilled intravenous fluids can adhere to them, posing a risk of pathogen transmission. Therefore, it is necessary to clean and disinfect the inner ring of the scanning gantry and the surface of the scanning bed regularly. However, currently, the cleaning and disinfection of the inner ring of the scanning gantry and the surface of the scanning bed are mostly done manually by medical staff, using disinfectant sprays and wiping. Manual cleaning is time-consuming and labor-intensive. Furthermore, because CT machines emit radiation, prolonged close contact during cleaning can significantly interfere with the health of medical staff. To address these issues, a CT equipment cleaning device is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the time-consuming and labor-intensive nature of manual cleaning of CT scanners, as well as the high safety risks involved, and to propose a CT equipment cleaning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A CT equipment cleaning device is designed, comprising a fixed frame and a synchronous cleaning mechanism. The synchronous cleaning mechanism is mounted on the fixed frame and includes two mounting brackets, two upper rollers, two lower rollers, a support mechanism, and a cleaning belt. The two mounting brackets are symmetrically spaced apart, with one mounting bracket fixedly connected to the fixed frame. The two upper rollers are rotatably mounted above the two mounting brackets, and the two lower rollers are rotatably mounted below the two mounting brackets. The support mechanism includes a first frame, a second frame, and a third frame. The first frame is symmetrically hinged to the inner side of the lower end of the two mounting brackets. The second and third frames are sequentially positioned above the first frame. A hinge plate is hinged between the first, second, and third frames. The cleaning belt is rotatably sleeved on the two upper rollers, the two lower rollers, and the hinge plate. A linkage mechanism is provided at the upper end of the two mounting brackets.

[0007] Preferably, a rotating shaft is rotatably mounted between the first frame, the second frame, and the third frame, and the rotating shaft is in contact with the cleaning belt.

[0008] Preferably, the linkage mechanism includes two connecting shafts, a horizontal plate, a bidirectional screw, a slide rod, and two movable seats. The two connecting shafts are symmetrically rotatably mounted on the upper ends of the two mounting brackets. The two ends of the horizontal plate are sleeved on the two connecting shafts. An installation groove is formed on the upper surface of the horizontal plate. The bidirectional screw is rotatably mounted in the middle of the installation groove. The slide rod is fixedly mounted in the installation groove and located on both sides of the bidirectional screw. The two movable seats are threadedly sleeved on the two ends of the bidirectional screw and slidably connected to the slide rod. A first support frame is hingedly mounted on the upper end of the two movable seats. The upper end of the first support frame is hingedly connected to the inner side of the hinge plate at the upper end of the first frame. A second support frame is hingedly mounted on the middle of the upper end of the two movable seats. The upper end of the second support frame is hingedly connected to the inner side of the hinge plate between the second frame and the third frame.

[0009] Preferably, each of the inner sides of the second support frame is hinged with a plug rod, and a sliding cylinder is slidably sleeved on an adjacent end of the plug rod, with a top plate fixedly installed above the sliding cylinder.

[0010] Preferably, a cleaning belt mechanism is provided between the two mounting frames. The cleaning belt mechanism is attached to the cleaning belt on both sides. The cleaning belt mechanism includes a box, a water supply tank, and a spray plate. The box is fixedly installed between the two mounting frames. End plates are fixedly installed at both ends of the box. The water supply tank is fixedly installed on one side above the box. A water pump is fixedly installed below the water supply tank. A water pipe is connected to the water pump. The spray plate is connected to the lower end of the water pipe and fixedly installed on one side of the box.

[0011] Preferably, a second scraper is fixedly installed on one side of the upper end of the box, a water collection tank is fixedly installed on the lower end of the box, a water channel is provided above the water collection tank near the spray plate, and one side of the water collection tank is in contact with the cleaning belt.

[0012] Preferably, a first scraper is fixedly installed on the upper end of the other side of the box, a partition is fixedly installed in the middle of the box, and water passage holes are arrayed and opened through the upper and lower sides of the other side of the box.

[0013] Preferably, a filter plate is inserted above the other side of the housing.

[0014] Preferably, a water collection tube is rotatably installed on the other side of the box, and water passage holes are formed through the circumferential array on the outer circular wall of the water collection tube.

[0015] Preferably, a support base is fixedly installed on the rear side of the fixed frame, a base plate is fixedly installed on the lower end of the support base, a counterweight is fixedly installed on the base plate, and omnidirectional wheels are arranged in an array below the base plate.

[0016] The CT equipment cleaning device proposed in this invention has the following advantages:

[0017] 1. The cleaning tape, wound around the upper and lower rollers in the synchronous cleaning mechanism, bends internally and is limited to a horizontal section, adapting to the surface of the scanning bed for cleaning. Meanwhile, the rotating shafts in the expansion mechanism, arrayed and mounted on the first, second, and third frames, connect with hinged plates, expanding the cleaning tape externally into a circle. This allows it to simultaneously conform to the inner ring of the circular scanning frame and the surface of the scanning bed. The rotation of the cleaning tape cleans the inner ring of the circular scanning frame and the surface of the scanning bed, effectively removing dust and cleaning patient bodily fluids, splashed blood, and spilled intravenous fluids. This achieves highly efficient cleaning for CT scans. In infectious disease departments, compared to frequent manual cleaning by medical staff, the cleaning speed is faster, easier to adjust, and reduces occupational exposure caused by manual cleaning, making it safer.

[0018] 2. The first support frame in the linkage mechanism is hinged to the hinge plates in the first and second frames, and the second support frame is hinged to the hinge plates in the second and third frames. The top plate abuts against the hinge plate in the middle of the third frame and the upper pivot, forming an adjustable support frame. This not only supports the first frame, hinge plates, second frame, and third frame, but also allows the cleaning belt to be supported and synchronously fit against the inner ring of the circular scanning frame and the surface of the scanning bed. At the same time, the synchronous movement of the moving seat can release the expanded state of the cleaning belt, making it easier to enter the inner ring of the circular scanning frame. When not in use, it can also reduce the stretching of the cleaning belt and extend its service life.

[0019] 3. The spray plate in the cleaning belt mechanism can spray disinfectant cleaning solution onto the cleaning belt, and the second scraper can scrape off the wastewater on the cleaning belt, thus achieving the first cleaning of the cleaning belt. This reduces the adverse cleaning effect of the soiled cleaning belt on the surface of the scanning bed. At the same time, since the surface of the scanning bed is in direct contact with the patient, it contains more dirt and bacteria. Therefore, the residual disinfectant cleaning solution is removed a second time by the first scraper and the water collection tube, thus achieving the second cleaning of the cleaning belt, which facilitates the cleaning of the inner ring of the circular scanning frame.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1

[0030] Reference Figure 1-5 A CT equipment cleaning device includes a fixed frame 1 and a synchronous cleaning mechanism 2. The synchronous cleaning mechanism 2 is mounted on the fixed frame 1 and includes two mounting brackets 21, two upper roller shafts 22, two lower roller shafts 23, a support mechanism 24, and a cleaning belt 26. The two mounting brackets 21 are symmetrically spaced apart. One mounting bracket 21 is fixedly connected to the fixed frame 1. The two ends of the two upper roller shafts 22 are rotatably mounted above the two mounting brackets 21. At the same time, a drive motor is fixedly mounted on the outer side of the upper end of one mounting bracket 21 corresponding to the two upper roller shafts 22. The output shaft of the drive motor passes through the mounting bracket 21 and is fixedly connected to the two upper roller shafts 22 respectively. Next, the two lower roller shafts 23 are rotatably mounted below the two mounting brackets 21 at both ends. The two upper roller shafts 22 and the two lower roller shafts 23 are all located in the middle of the two mounting brackets 21. The two upper roller shafts 22 and the two lower roller shafts 23 mainly guide the movement trajectory of the cleaning belt 26, so that the upper part of the cleaning belt 26 rotates in a circular manner to clean the inner circle of the circular scanning frame, while the lower part of the cleaning belt 26 protrudes inward, thereby covering the upper surface of the scanning bed. The expansion mechanism 24 is set on the mounting bracket 21. The expansion mechanism 24 includes a first frame 241, a second frame 243, and a third frame 244. The first frame 241 is symmetrically hinged to the inner side of the lower end of the two mounting brackets 21. The second frame 243 and the third frame 244 are sequentially arranged above the first frame 241. A hinge plate 242 is hinged between the first frame 241, the second frame 243, and the third frame 244, so that the first frame 241, the second frame 243, and the third frame 244 cooperate with the hinge plate 242 to form an arched frame, which supports the cleaning belt 26. At the same time, when the arched frame is fully supported, it can adapt to the inner circle of the circular scanning frame, thereby avoiding cleaning the four corners. The cleaning belt 26 is rotatably sleeved on the two upper roller shafts 22, the two lower roller shafts 23, and the hinge plate 242. The cleaning belt 26 is slightly stretchable and has a certain... The fabric has varying tension. A rotating shaft 245 is rotatably mounted between the first frame 241, the second frame 243, and the third frame 244. The rotating shaft 245 is in contact with the cleaning belt 26. The cleaning belt 26 is in direct contact with the rotating shaft 245, the two upper roller shafts 22, and the two lower roller shafts 23. At the same time, a limiting band 261 is provided on the inner side of the cleaning belt 26. Limiting grooves are opened on the outer circular walls of the two upper roller shafts 22 and the two lower roller shafts 23. The limiting band 261 is in the limiting groove. Meanwhile, the diameter of the rotating shaft 245 is smaller than the width of the first frame 241, the second frame 243, and the third frame 244, thereby limiting the cleaning belt 26 and preventing it from slipping during rotation.

[0031] The cleaning belt 26 is wound around the upper roller 22 and lower roller 23 in the synchronous cleaning mechanism 2, causing it to bend internally and be limited to a horizontal section, which can adapt to the surface of the scanning bed for cleaning. The rotating shaft 245 in the expansion mechanism 24, which is rotatably mounted on the first frame 241, the second frame 243 and the third frame 244, and the hinge plate 242, which serves as a connection, expand the cleaning belt 26 sleeved on it externally into a circle, so that it can synchronously fit the inner circle of the circular scanning frame and the surface of the scanning bed. The rotation of the cleaning belt 26 realizes the cleaning work of the inner circle of the circular scanning frame and the surface of the scanning bed. It can effectively remove the dust attached to the inner circle of the circular scanning frame and the surface of the scanning bed, and can effectively clean the patient's flowing body fluid, splashed blood and overflowing intravenous infusion fluid, thus achieving efficient cleaning of CT scans. When used in infectious disease departments, compared with the frequent manual cleaning by medical staff, the cleaning speed is faster, it is easier to adjust, and it reduces occupational exposure caused by manual cleaning, making it safer.

[0032] Two mounting brackets 21 are equipped with a linkage mechanism 25 at their upper ends. The linkage mechanism 25 includes two connecting shafts 251, a horizontal plate 252, a bidirectional screw 253, a sliding rod 254, and two movable seats 255. The two connecting shafts 251 are symmetrically and rotatably mounted on the upper ends of the two mounting brackets 21. The two ends of the horizontal plate 252 are sleeved on the two connecting shafts 251. The upper surface of the horizontal plate 252 has a mounting groove. The bidirectional screw 253 is rotatably mounted in the middle of the mounting groove. A motor is fixedly mounted at one end of the mounting groove. The motor output shaft is fixedly connected to the bidirectional screw 253. The sliding rod 254 is fixedly mounted in the mounting groove and located on both sides of the bidirectional screw 253. The two movable seats 255 are threadedly sleeved on both ends of the bidirectional screw 253 and slidably connected to the sliding rod 254. A first support frame 256 is hinged to the upper end of the 55. The upper end of the first support frame 256 is hinged to the inner side of the hinge plate 242 at the upper end of the first frame 241. A second support frame 257 is hinged to the middle of the upper end of the two movable seats 255. The upper end of the second support frame 257 is hinged to the inner side of the hinge plate 242 between the second frame 243 and the third frame 244. Insert rods 2571 are hinged to the inner side of the second support frame 257. A slide cylinder 258 is slidably sleeved on one adjacent end of the insert rod 2571. Springs are fixedly installed inside both ends of the slide cylinder 258, and the other end of the springs is fixedly connected to the insert rod 2571. A top plate 259 is fixedly installed above the slide cylinder 258. The top of the top plate 259 abuts against the hinge plate 242 in the middle of the third frame 244.

[0033] The first support frame 256 in the linkage mechanism 25 is hinged to the hinge plate 242 in the first frame 241 and the second frame 243. The second support frame 257 is hinged to the hinge plate 242 in the second frame 243 and the third frame 244. The top plate 259 abuts against the hinge plate 242 in the middle of the third frame 244 and the upper pivot 245, forming an adjustable support frame. This frame not only provides simultaneous support for the first frame 241, the hinge plate 242, the second frame 243, and the third frame 244, but also allows the cleaning belt 26 to be supported and fit against the inner ring of the circular scanning frame and the upper surface of the scanning bed. At the same time, the cleaning belt 26 can be released from its expanded state by the synchronous movement of the moving seat 255, making it easier to enter the inner ring of the circular scanning frame. When not in use, this also reduces the stretching of the cleaning belt 26 and extends its service life.

[0034] A support base 4 is fixedly installed on the rear side of the fixed frame 1. A base plate 5 is fixedly installed on the lower end of the support base 4. A counterweight 6 is fixedly installed on the base plate 5. A caster wheel 7 is arranged in an array below the base plate 5. The support base 4, base plate 5, and caster wheel 7 are set to support the device and facilitate its movement. The counterweight 6 is set to prevent the device from tilting due to the center shifting forward, thus playing a balancing role.

[0035] Example 2

[0036] According to Embodiment 1, the cleaning belt 26 can expand and fit against the inner ring of the circular scanning frame and the surface of the scanning bed, and the cleaning work on the inner ring of the circular scanning frame and the surface of the scanning bed is achieved by the rotation of the cleaning belt 26. However, the cleaning belt 26 will gradually become dirty during the cleaning process. If it is not cleaned and disinfected in time, it will cause secondary contamination of the inner ring of the circular scanning frame and the surface of the scanning bed. Refer to Figure 1 , 6 -7. As another preferred embodiment of the present invention, based on embodiment 1, it further includes a cleaning belt mechanism 3.

[0037] The cleaning belt mechanism 3 is positioned between two mounting brackets 21, with both sides of the mechanism conforming to the cleaning belt 26. The mechanism 3 includes a housing 31, a water supply tank 36, and a spray plate 37. The housing 31 is fixedly installed between the two mounting brackets 21, with end plates fixedly installed at both ends. The water supply tank 36 is fixedly installed on one side above the housing 31. The water supply tank 36 is filled with disinfectant and disinfectant solution, achieving disinfection in 2-3 minutes. It is non-corrosive to surfaces, non-irritating to humans, and non-allergenic. A water pump 361 is fixedly installed below the water supply tank 36, connected to a water pipe. The spray plate 37 is connected to the lower end of the water pipe. It is fixedly installed on one side of the housing 31. A second scraper 38 is fixedly installed on one side of the upper end of the housing 31. A water collection tank 35 is fixedly installed at the lower end of the housing 31. A water inlet trough 39 is opened on the side of the water collection tank 35 near the spray plate 37. One side of the water collection tank 35 is in contact with the cleaning belt 26. The water pump 361 sprays the card cloth and card liquid in the water supply tank 36 evenly onto the side of the cleaning belt 26 that is in contact with the inner ring of the circular scanning frame and the upper surface of the scanning bed. The second scraper 38 squeezes the cleaning belt 26 to discharge the dirt solution adsorbed in the cleaning belt 26, which facilitates the removal of dust and stains attached to the cleaning belt 26 and can disinfect the cleaning belt 26.

[0038] A first scraper 33 is fixedly installed on the upper end of the other side of the housing 31. A partition 32 is fixedly installed in the middle of the housing 31. Water passage holes 312 are arranged in an array on the upper and lower sides of the other side of the housing 31. A filter plate 311 is inserted on the upper side of the other side of the housing 31. A water collection cylinder 34 is rotatably installed on the other side of the housing 31. Water passage holes are arranged in an array on the outer circumference of the outer wall of the water collection cylinder 34.

[0039] The spray plate 37 in the cleaning belt mechanism 3 can spray disinfectant cleaning solution onto the cleaning belt 26, and the second scraper 38 scrapes off the sewage on the cleaning belt 26, thus achieving the first cleaning of the cleaning belt 26 and reducing the adverse cleaning effect of the soiled cleaning belt 26 on the surface of the scanning bed. At the same time, since the surface of the scanning bed is in direct contact with the patient, it has more dirt and bacteria. Therefore, the residual disinfectant cleaning solution is removed a second time by the first scraper 33 and the water collection tube 34, thus achieving the second cleaning of the cleaning belt 26, so as to facilitate the cleaning of the inner ring of the circular scanning frame.

[0040] Device Arrangement: When cleaning the CT scanner is required, first reset the scanning bed, i.e., move it away from the scanning gantry. At this time, push the support base 4 and the base plate 5 to align the synchronous cleaning mechanism 2 with the scanning gantry. At this time, both moving seats 255 are close to the middle of the horizontal plate 252. That is, the first support frame 256, the second support frame 257, and the top plate 259 do not expand the cleaning belt 26, making the cleaning belt 26 loose and easy to enter the scanning gantry. After the synchronous cleaning mechanism 2 enters the scanning gantry, the motor at one end of the control mounting slot drives the bidirectional screw 253 to rotate. Through the threaded connection between the bidirectional screw 253 and the two moving seats 255, the two moving seats 255 are moved outward, thereby supporting the first support frame 256, the second support frame 257, and the top plate 259, which in turn expands the first frame 241, the second frame 243, and the third frame 244, stretching the cleaning belt 26 to adhere to the inner surface of the scanning gantry.

[0041] Equipment cleaning: Then turn on the drive motor to drive the two upper roller shafts 22 to rotate, which in turn drives the cleaning belt 26 to rotate. At this time, move the scanning bed so that it moves slowly toward the synchronous cleaning mechanism 2 and contacts the horizontal section of the cleaning belt 26 in the middle of the two upper roller shafts 22. Then, the rotating cleaning belt 26 adheres to and cleans the inner ring of the circular scanning frame and the upper surface of the scanning bed.

[0042] Cleaning and disinfection of the cleaning belt: During the rotation of the cleaning belt, the water pump 361 sprays the cava cloth and cava liquid in the water supply tank 36 evenly through the spray plate 37 onto the side of the cleaning belt 26 that is in contact with the inner ring of the circular scanning frame and the surface of the scanning bed. The cleaning belt 26 rotates upward after passing through the spray plate 37 and contacts the second scraper 38. The squeezing action of the second scraper 38 on the cleaning belt 26 causes the adsorbed dirt solution in the cleaning belt 26 to be discharged. The upper end of the water inlet trough 39 contacts the cleaning belt 26, so that the wastewater scraped by the second scraper 38 flows along the cleaning belt 26 and the water inlet trough 39 under the action of gravity. Inside the water collection tank 35, the cleaning belt 26 rotates to contact and clean the surface of the scanning bed. Then, the cleaning belt 26 rotates to contact the first scraper 33, which scrapes off the residual sewage on the cleaning belt 26. The sewage flows into the water collection tank 35 through the water hole 312 on the housing 31. At the same time, the filter plate 311 can filter hair or other debris carried in the sewage. The filter plate 311 can be replaced. Then, the sewage in the cleaning belt 26 is squeezed by the water collection cylinder 34, which further squeezes out the sewage into the water collection cylinder 34 and finally flows into the water collection tank 35.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
