Description

Technical Field

[0001] This utility model relates to the field of protective chamber technology, specifically a CT protective chamber. Background Technology

[0002] The CT protective chamber provides comprehensive protection for medical staff and patients. It comes with lead plates to effectively block radiation and protect medical staff and patients from radiation damage. In addition, the protective chamber is equipped with air conditioning, sterilizers, negative pressure purification, air disinfection and ultraviolet disinfection equipment to ensure a clean and safe environment. The CT protective chamber is also easy to move and use flexibly. It has a small footprint and can be moved anytime and anywhere without too many restrictions on the site. This makes it possible to quickly deploy the CT protective chamber in emergency situations.

[0003] For example, a CT protective device disclosed in the authorization announcement number CN210277196U includes a CT bed. An elastic band and a metal ring are fixed from top to bottom at the front end of the CT bed, and a hook is fixed at the lower end of the elastic band. Support rods are welded symmetrically at the upper and lower ends of the CT bed, and an upper round rod and a lower round rod are installed on the support rods.

The outside of the base 1 is symmetrically arranged with rollers 20. The two ends of each roller 20 are movably fitted with a support sleeve 13, and the support sleeve 13 is fixedly connected to the base 1. The side wall of the base 1 on one side of the roller 20 is equipped with a support plate 10.

[0028] When using the CT protective chamber, the chamber is connected to the sliding plate of the CT machine and can be securely fixed to it. The grounding wire 9 is loosened to the ground surface to discharge static electricity from the patient, reducing interference with the images. A disposable sheet body 19 is placed on top of the base 1, and the patient lies on it. Depending on the examination area, multiple sets of lead plates 4 are placed inside the groove 3 and moved to the appropriate position using the side handle 7 to block X-rays from areas that do not need exposure. The lead shield 5 is placed on the guide rod 2 above the base 1 using the upper handle 21. The lead shield 5 slides on the surface of the guide rod 2 via the retaining ring 22. Depending on the examination area, the sliding lead shield 5 blocks and shields areas that do not need to be examined. Above, to avoid radiation damage to the human body, the lead shield 5 of the area to be examined is moved away to expose the area to be examined, so that CT rays can pass through and obtain examination data. During the sliding of the lead shield 5, the indicator red light 6 can be seen through the controller 8 to project light onto the patient's body surface, indicating the position of the sliding shield of the lead shield 5, and clearly defining the radiation shielding range of each lead shield 5. It is convenient to move the position according to the light of the indicator red light 6. The sliding of the lead shield 5 corresponds one-to-one with the lead plate 4, realizing convenient modular movement of the CT protective chamber to shield X-rays. It is convenient for each group of modules to move and adjust the X-ray shielding position independently, improving the convenience of the CT protective chamber for mobile protection of the human body and avoiding radiation damage to other parts of the human body.

[0029] Rotating rods 11 are movably installed inside the support plate 10. The rotating rods 11 all pass through the support plate 10 and extend to the surface of the support sleeve 13. A handle 18 is installed at the end of the rotating rod 11 away from the support sleeve 13, and a first right angle gear 12 is installed at the end of the rotating rod 11 close to the support sleeve 13.

[0030] Worms 14 are movably installed on the side walls of the support sleeve 13. A second right-angle gear 15 is installed at the end of the worm 14 near the rotating rod 11. The second right-angle gear 15 meshes with the first right-angle gear 12. A support shaft 17 is installed at one end of the outer roller 20 of the support sleeve 13.

[0031] The support shaft 17 is equipped with a worm gear 16 at the end away from the roller 20. The worm gear 16 meshes with the worm 14. The surface of the roller 20 is covered with a disposable bed sheet body 19, and the disposable bed sheet body 19 covers the top of the base 1 and extends to the other side of the base 1 to contact another set of rollers 20.

[0032] A controller 8 is installed on the side wall of the base 1 on one side of the roller 20. The output terminal of the controller 8 is electrically connected to the input terminal of the indicator red light 6.

[0033] When a patient's examination is completed and the disposable bed sheet needs to be re-laid, the two sets of handles 18 are turned. One set of handles 18 rotates clockwise, and the other set rotates counterclockwise. Supported by the support plate 10, the handles 18 drive the rotating rod 11 to rotate. Supported by the support sleeve 13, the rotating rod 11 drives the first right-angle gear 12 to rotate. With the first right-angle gear 12 meshing with the second right-angle gear 15, the first right-angle gear 12 drives the second right-angle gear 15 and the worm gear 14 to rotate. With the worm gear 14 meshing with the worm wheel 16, the worm gear 14 drives the worm wheel 16 to rotate. The worm gear 16 drives the support shaft 17 and roller 20 to rotate. The roller 20 drives the unused disposable bed sheet body 19 to be released and replaced on the surface of the base 1. At the same time, the handle 18 on the other side of the base 1 is turned in the opposite direction, so that another set of rollers 20 rolls up the used disposable bed sheet body 19 and replaces it with a new disposable bed sheet, which is convenient for the next patient to use. This facilitates the replacement of disposable bed sheets, avoids the risk of cross-infection, and ensures the safety of the CT protective chamber for the human body. It also improves the flexibility and convenience of replacing disposable bed sheets in the CT protective chamber.

[0034] Working principle: Depending on the examination site, multiple sets of lead plates 4 are placed inside the groove 3 and moved to the appropriate position via the side handle 7 to block X-rays from areas that do not need to be exposed. The lead shield 5 is placed on the guide rod 2 above the base 1 via the upper handle 21. The lead shield 5 slides on the surface of the guide rod 2 via the retaining ring 22. Depending on the examination site, the sliding lead shield 5 blocks and shields areas that do not need to be examined, preventing radiation damage to the body. Simultaneously, the lead shield 5 for the area to be examined is moved away, exposing the area to be examined, allowing CT rays to pass through and obtain examination data. During the sliding of the lead shield 5, the indicator red light 6 illuminates the patient's skin, indicating the position of the sliding lead shield 5 and clearly defining the shielding range of each lead shield 5. This facilitates the movement of the lead shield 5 according to the light from the indicator red light 6. The sliding of the lead shield 5 corresponds one-to-one with the lead plate 4. After one patient's examination is completed, the process needs to be repeated. When laying out the disposable sheet, turn both sets of handles 18. One set of handles 18 rotates clockwise, and the other set rotates counterclockwise. With the support of the support plate 10, the handles 18 drive the rotating rod 11 to rotate. With the support of the support sleeve 13, the rotating rod 11 drives the first right-angle gear 12 to rotate. Under the meshing of the first right-angle gear 12 and the second right-angle gear 15, the first right-angle gear 12 drives the second right-angle gear 15 and the worm gear 14 to rotate. The worm gear 14 drives the worm wheel 16 to rotate. The worm wheel 16 drives the support shaft 17 and the roller 20 to rotate. The roller 20 drives the unused disposable sheet body 19 to be released and replaced on the surface of the base 1. At the same time, turn the handle 18 on the other side of the base 1 in the opposite direction so that the other set of rollers 20 rolls up the used disposable sheet body 19 and replaces it with a new disposable sheet for the next patient. This convenient and quick replacement of disposable sheets completes the use of the protective chamber.
