Description

Technical Field

[0001] The invention relates to the technical field of optical therapeutic instruments, and in particular to an LED optical therapeutic instrument for treating vaginitis. Background Art

[0002] Candida vaginitis or candidal vaginitis, also known as vulvovaginal candidiasis (VVC), is a common and frequent vulvovaginal inflammatory disease caused by Candida albicans. Candida albicans is an opportunistic pathogen. 10% to 20% of non-pregnant women and 30% of pregnant women have this fungus in their vagina, but the amount of bacteria is small and does not cause symptoms. Only when the systemic and local vaginal immunity decreases, especially the local cellular immunity decreases, and Candida albicans multiplies in large numbers, will vaginitis symptoms occur. For simple vulvovaginal candidiasis, local medication is mainly used. Generally, the symptoms are alleviated or disappear 2-3 days after medication. Clotrimazole vaginal suppository, used every 3 days, a total of 2 times. Regarding the treatment of complicated vulvovaginal candidiasis, the selected drugs are basically the same as those for simple vulvovaginal candidiasis. Whether it is local medication or systemic medication, the treatment time should be appropriately extended. When treating candidal vaginitis, the hands contain a large number of bacteria when inserting the suppository into the affected area, which may have some impact on the treatment.

[0003] When using tools to inject suppositories into the vagina, it is easy to cause the medicine to shift in position because the location of the disease cannot be seen, and it cannot achieve a good therapeutic effect. Summary of the invention

Before use, a medicine suppository is installed in the elastic clip 42 of the front tube 41, the vagina is opened by the inner support plate 2, and the location of the disease is observed. Then the movable tube 1 is rotated to dock with the outer end of the inner support plate 2, and the front tube 41 is pushed to move by the pushing component 4 until it is close to the treatment position. The angle of the front tube 41 can be rotated to facilitate the treatment and irradiation sterilization of diseases in different positions, thereby improving the treatment effect.

When the moving cylinder 1 is in a vertical state, the position of the disease is observed in the space supported by the two inner support plates 2, and the length to be moved is determined according to the scale mark 21. When the screw is pushed forward, the moving position can be determined according to the scale of the tooth plate 41146, which can effectively reduce the deviation between the position where the suppository is used and the position irradiated by the irradiation lamp 43 and the position where the disease is located.

[0035] In this embodiment, a fixing ring 415 is fixed on the surface of the side of the front tube 41 away from the rotating shaft 49, and a moving ring 417 is slidably sleeved on the surface of the front tube 41 close to the rotating shaft 49, a spring 416 is fixed between the moving ring 417 and the fixing ring 415, a connecting rod 414 is rotatably connected to the position on the outer surface of the moving ring 417 corresponding to the back of the irradiation lamp 43 through a rotating shaft, and the other end of the connecting rod 414 is rotatably installed on the back of the irradiation lamp 43, a sliding groove 412 is opened on the back of the irradiation lamp 43, and a slider 413 is slidably connected in the sliding groove 412, and the other end of the connecting rod 414 is rotatably connected to the slider 413 through a rotating shaft, cylinders 419 are installed on both sides of the upper end of the rotating shaft 49, an extension plate 418 is fixed on the top of the moving ring 417, and the extension plate 418 is squeezed and contacted with the cylinder 419 after rotation. In the initial state, the front tube 41 and the middle tube 48 remain in the same straight line. At this time, the extension plate 418 does not contact the cylinders 419 on both sides, and the movable ring 417 is also away from the fixed ring 415. When the rotating shaft 49 drives the front tube 41 to rotate, the cylinder 419 here is in a fixed position, which can be understood as being fixed to the rear middle tube 48 by a connecting piece and does not rotate with the rotating shaft 49. During the rotation of the front tube 41, the extension plate 418 will contact the circular surface of the cylinder 419 on one side, and squeeze the movable ring 417 to move toward the side of the fixed ring 415, and drive the slider 413 to slide along the slide groove 412 through the connecting rod 414, and push the irradiation lamp 43 to rotate, so that it is gathered toward the diseased area, thereby improving the light treatment effect. Similarly, when the front tube 41 rotates to restore the initial position, the movable ring 417 and the irradiation lamp 43 are reset by the elastic force of the spring 416.

[0036] Before use, the movable cylinder 1 can be pushed by translation so that the outer end of the inner support plate 2 is inserted into the slot 12. At this time, the plug plate 37 is just separated from the plug frame 38, keeping the movable cylinder 1 and the inner support plate 2 in the same straight line to avoid being affected by the turntable 33. When the movable cylinder 1 moves backward, the plug plate 37 is inserted into the plug frame 38. At this time, there is a rotation space between the movable cylinder 1 and the inner support plate 2. The movable cylinder 1 can be changed to a vertical state by rotating the turntable 33, so as to facilitate the observation of the disease position before medication treatment and the installation of the therapeutic suppository inside the front tube 41. The vagina is opened by the inner support plate 2. When the movable cylinder 1 is in the vertical state, the position of the disease is observed according to the space supported by the two inner support plates 2, and the length to be moved is determined according to the scale mark 21. When it is pushed by the screw, the moving position can be determined according to the scale of the scale 4641146, which can effectively reduce the deviation between the position of the suppository used and the position irradiated by the irradiation lamp 43 and the position of the disease. The front tube 41 is moved to dock with the outer end of the inner support plate 2, and the front tube 41 is pushed to move by the pushing component 4 until it is close to the treatment position. In the initial state, the front tube 41 and the middle tube 48 are kept in the same straight line. At this time, the extension plate 418 does not contact the cylinders 419 on both sides, and the movable ring 417 is also away from the fixed ring 415. When the rotating shaft 49 drives the front tube 41 to rotate, the cylinder 419 here is in a fixed position, which can be understood as being fixed to the rear middle tube 48 by a connecting piece and does not rotate with the rotating shaft 49. During the rotation of the front tube 41, the extension plate 418 will contact the circular surface of the cylinder 419 on one side, and squeeze the movable ring 417 to move toward the side of the fixed ring 415, and drive the slider 413 to slide along the slide groove 412 through the connecting rod 414, and push the irradiation lamp 43 to rotate, so that it is gathered toward the diseased area, thereby improving the light treatment effect. Similarly, when the front tube 41 rotates to restore the initial position, the movable ring 417 and the irradiation lamp 43 are reset by the elastic force of the spring 416, thereby improving the treatment effect.
