Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a lung CT film auxiliary judgment and viewing device. Background Art

[0002] CT scans are a means of diagnosing a variety of diseases by viewing medical images. They use precisely collimated X-ray beams, gamma rays and ultrasound waves together with highly sensitive detectors to perform cross-sectional scans one after another around a certain part of the human body. They have the characteristics of fast scanning time and clear images. When reading CT scans, people usually hold the CT scans directly against the light source for viewing, but this obviously causes many viewing inconveniences. First, the number of CT scans viewed at one time is small, usually one or two, and additional lighting is required, which is time-consuming and labor-intensive. In addition, it is not convenient to use multiple CT scans to compare and explain the condition to the patient, and the practicality is poor. On the other hand, existing CT scans are prone to bending or offset during viewing, resulting in a certain error in the viewing angle, thereby affecting the judgment of the condition. Existing auxiliary viewing devices have made great improvements to the above problems, but they still have disadvantages. They are too large, bulky, and inflexible. They cannot be carried around, and are not convenient for explaining the condition to the patient anytime and anywhere.

The second slider (409) is composed of three parts: a slide cylinder, a first extension column and a second extension column. The first extension column is fixed to the side of the slide cylinder, and the second extension column is fixed to the other end of the first extension column. The second extension column is located in the rotating cylinder (410); Two stoppers are fixed on the pillar (604), the two stoppers are respectively located on both sides of the third gear (609) and are clearance-matched with the third gear (609), so as to facilitate the limiting of the third gear 609; the fourth gear (610) is meshed with teeth in the third groove (12); the length of the cylinder (611) is greater than the width of the CT film body (18), so as to facilitate the cleaning of the CT film body 18; When in use, first place the device on the desktop so that the support block 308 contacts the desktop, rotate the rotating plate 5 180 degrees, at this time the connecting plate 2 is directly above, then press the pressing blocks 303 on both sides, so that the cross plate 301 drives the end face of the second slide bar 304 to separate from the end face of the locking ring 309, at this time the spring 306 is in a compressed state, then place the arranged CT sheet body 18 on the connecting plate 2, and align the fixing holes 19 on the CT sheet body 18 with the two end faces, release the pressing blocks 303 on both sides, the spring 306 will drive the pressing blocks 303 to reset, and at the same time the end face of the second slide bar 304 passes through the fixing holes 19 and is aligned with the locking ring 3 09 end surfaces are fitted together to complete the position limiting of the CT film body 18. At this time, the CT film body 18 can be turned over along the locking ring 309. Pick up the device. At this time, if you want to view a specific CT film body 18, you only need to turn the CT film above the CT film body 18 and the CT film body 18 upward along the locking ring 309, and then rotate the rotating plate 5 to make it close to the connecting plate 2 or the other CT film bodies 18, and then rotate the CT film body 18 downward to cover it on the lampshade 13. Before viewing, rotate the pull rod 601 and place the bottom end of the CT film body 18 between the two cleaning sleeves 612, and pull the pull rod 601 to make the cleaning group The component 6 is moved as a whole to the top of the third groove 12. At this time, the two cleaning sleeves 612 are respectively located on both sides of the top of the CT film body 18. At this time, the pull rod 601 is rotated and pulled downward. Since the fourth gear 610 is engaged with the teeth on one side of the third groove 12, it will drive the second round rod 606 to rotate. The rotating second round rod 606 will drive the second gear 608 to rotate. The second gear 608 will drive the first gear 607 through the third gear 609 and then drive the first round rod 605 to rotate. The rotating first round rod 605 and the second round rod 606 will drive the cleaning sleeves 612 thereon to rotate on the surfaces of both sides of the CT film body 18. When the fourth gear 610 is located at the bottom of the third groove 12, the stains on the surface of the CT film body 18 are cleaned. By triggering the switch to close the circuit, the light is evenly irradiated on the bottom surface of the CT film body 18 through the lampshade 13. To enlarge a certain part of the CT film body 18, the first slider 403 can be moved up and down in conjunction with the knob 406 to move the convex mirror 412 up and down. The second slider 409 can be slid to move the convex mirror 412 in the horizontal direction. The rotating ring cylinder 411 can adjust the angle between the convex mirror 412 and the CT film body 18. The convex mirror 412 is moved to the part that needs to be enlarged and then observed.
