Description

Technical Field

[0001] This invention relates to the technical field of ultraviolet therapy devices, and more particularly to an ultraviolet therapy device capable of mapping area skin treatment. Background Technology

[0002] Ultraviolet (UV) therapy devices are medical instruments that treat skin diseases by emitting specific wavelengths of ultraviolet light (mainly UVA and UVB). The principle behind this is to utilize the biological effects of UV light to inhibit excessive immune responses or excessive cell proliferation in the skin, and to kill bacteria. It is primarily used to treat psoriasis, vitiligo, atopic dermatitis, eczema, and lymphoma.

[0003] Currently, for skin lesions with irregular shapes (such as meandering borders or island-like appearance) or scattered locations (such as psoriasis, vitiligo, and eczema), treatment with UVA / UVB phototherapy equipment mainly relies on physical covering cloths to define the treatment area. Medical staff need to manually cut the covering cloth according to the approximate shape of the lesions in advance and cover the healthy skin to expose the treatment area. This method has significant drawbacks: First, the operation is extremely cumbersome and time-consuming, especially when dealing with complex or irregularly shaped lesions, where precise cutting is difficult and repeated adjustments are necessary. Second, when a patient has multiple scattered treatment areas, a cyclical process of "cutting-covering-irradiation-removal-relocation-repetition" must be performed one by one, greatly prolonging the treatment time per session, reducing efficiency, and increasing the burden on medical staff. Third, the edges of manually cut covering cloths are usually rough and difficult to completely conform to the skin contour, easily leading to two risks: one is that ultraviolet light leaks and irradiates healthy skin around the lesion, causing unexpected photodamage and sunburn, which may increase the risk of aging or even cancer in the long term; the other is that excessive covering to avoid leakage may miss some lesion edge areas, affecting the treatment effect. In addition, repeated cutting and use of covering cloths also increases the cost of consumables and the difficulty of disinfection management. Summary of the Invention

[0004] In view of the above-mentioned problems in the existing technology, an ultraviolet therapy device capable of depicting regional skin treatment is proposed.

[0005] One aspect of this application provides an ultraviolet therapy device for treating skin in designated areas, the purpose of which is to cover skin in non-treatment areas and is reusable.

[0006] The technical solution of the present invention is as follows: an ultraviolet therapy device for treating skin in a specific area, comprising a shell, a lampshade on the shell, an ultraviolet therapy lamp at the bottom of the lampshade, a fixed first clamping edge on one side of the inner wall of the lampshade, a rotating second clamping edge on the other side, and a shielding unit clamped between the first clamping edge and the second clamping edge. The shielding unit includes a frame with two parallel shielding rods inside. The shielding rods divide the frame into three areas. The middle area has a horizontally folded horizontal shielding group, and the upper and lower areas have vertically folded vertical shielding groups. Both the horizontal and vertical shielding groups are composed of multiple shielding panels connected to each other.

[0007] Furthermore, a slide rail is provided on both sides of the frame, and a sliding block is provided at both ends of the shielding rod, and the sliding block slides within the slide rail.

[0008] Furthermore, the shielding sheets within the lateral shielding group have a retractable nested structure.

[0009] Furthermore, all the shielding plates are inclined, and their two sides are provided with curved portions in opposite directions for connecting adjacent shielding plates.

[0010] Furthermore, the shielding rod is provided with a cylindrical cavity, and a rotating shaft is rotatably provided in the cylindrical cavity. One end of the rotating shaft is fitted with an adjustment knob, which is partially exposed outside the shielding rod. Multiple friction rings are continuously fitted on the rotating shaft, and shielding windings are fitted on the friction rings. One end of the shielding winding passes through the shielding rod in the longitudinal shielding direction.

[0011] Furthermore, a baffle is provided at the end of the shielding winding that extends out of the shielding rod, and the shielding rod is provided with a groove to accommodate the baffle.

[0012] Furthermore, the cross-section of the shielding winding is arc-shaped.

[0013] Furthermore, each end of the shielding plate in the longitudinal shielding group is provided with a sliding block 2, which slides within the slide rail 1.

[0014] Furthermore, each of the two shielding rods is provided with a slide rail two on one side, and each of the shielding plates in the transverse shielding group is provided with a sliding block three at both ends, and the sliding block three slides within the slide rail two.

[0015] Furthermore, the sliding friction between the rotating shaft and the cylindrical cavity is greater than the sliding friction between the friction ring and the rotating shaft.

[0016] The beneficial effects of this invention are: 1. This ultraviolet therapy device, capable of depicting specific areas of skin, adjusts the coverage area through folding or unfolding the shielding sheets in both horizontal and vertical shielding groups. This creates a rectangular open space covering the treatment area by creating a break in the middle of the horizontal shielding group. Furthermore, within a cylindrical cavity along the length of the shielding rod, a rotating shaft can be driven to rotate via an end adjustment knob. This rotation causes the shielding winding wound around the shaft to extend or retract. The shielding winding extends from the shielding rod towards the vertical shielding group, and its extension length can be adjusted according to the actual shape of the treatment area, providing secondary shielding of the rectangular open space. Its curved cross-section design enhances rigidity during extension, preventing bending. Ultimately, through the layered effect of "initial shielding forming a basic range + secondary shielding precisely adapting to the shape," ultraviolet light is applied only to the area to be treated, achieving precise treatment.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Example 1, referring to Figures 1-9 This invention provides a first embodiment of an ultraviolet therapy device for treating skin areas, comprising a housing 1, a lampshade 2 on the housing 1, an ultraviolet therapy lamp 3 at the bottom of the lampshade 2, a fixed retaining edge 4 on one side of the inner wall of the lampshade 2, and a rotating retaining edge 5 on the other side, with a shielding unit sandwiched between retaining edge 4 and retaining edge 5; the shielding unit includes a frame 6, with two parallel shielding rods 7 inside the frame 6, dividing the frame 6 into three areas, with a horizontally folded horizontal shielding group 8 in the middle area and vertically folded vertical shielding groups 9 in the upper and lower areas, both the horizontal shielding group 8 and the vertical shielding group 9 being formed by multiple shielding sheets 10 connected to each other. The shielding sheets 10 in the horizontal shielding group 8 have a retractable nested structure. Slide rails 11 are provided on both sides of the frame 6, and sliding blocks 12 are provided at both ends of the shielding rods 7, sliding within the slide rails 11. Each end of the shielding plate 10 in the longitudinal shielding group 9 is provided with a sliding block 21, which slides within the slide rail 11. Each of the two shielding rods 7 has a slide rail 22 on one side opposite to the other. Each end of the shielding plate 10 in the transverse shielding group 8 is provided with a sliding block 23, which slides within the slide rail 22. All shielding plates 10 are inclined, and their two sides have oppositely oriented curved portions 13 for connecting adjacent shielding plates 10.

[0021] Specifically, the ultraviolet therapy lamp 3 uses a dedicated medical ultraviolet lamp array, which is fixedly installed on the lamp holder at the bottom of the lamp cover 2. The lamp holder is electrically connected to the control circuit board, and the lamp can be switched on and off and the light intensity can be adjusted via the adjustment buttons on the surface of the outer shell 1. One side of the inner wall of the lamp cover 2 has a single-layer, long strip structure with a gap between the two layers for clamping. Its length matches the width of the inner wall of the lamp cover 2, and the raised inner edge is designed with a smooth, rounded transition to avoid scratches during the installation of the shielding unit. The other side has a hinged second side 5 that is movably connected to the inner wall of the lamp cover 2. The user can control the rotation angle of the second side 5 to clamp the shielding unit within the first and second sides 4 and 5. The ultraviolet therapy lamp 3 is positioned behind the shielding unit. This positional relationship allows the ultraviolet rays emitted by the therapy lamp to be filtered by the shielding unit. Through the shielding and guiding of the ultraviolet rays by the shielding unit, the ultraviolet rays are precisely applied to the area to be treated, avoiding unnecessary irradiation of surrounding healthy skin.

[0022] The shielding unit includes a frame 6, which serves as the mounting carrier for the shielding components, providing a stable installation space and movement boundaries for the internal parts. Two parallel shielding rods 7 are installed within the frame 6, dividing the space into three zones. The middle zone contains a horizontally folding shielding group 8, while the upper and lower zones contain corresponding vertically folding shielding groups 9. Both the horizontal and vertical shielding groups 8 and 9 are composed of multiple shielding panels 10 interconnected, allowing adjustment of the shielding range through the folding and unfolding of the panels 10. The shielding panels 10 within the horizontal shielding group 8 have a retractable nested structure, which provides greater flexibility in adjusting the width of the horizontal shielding group 8, allowing the overall length to be changed by extending or retracting the nested sections. The shielding rods 7 can slide up and down within the frame 6. In actual operation, the position of the two shielding rods 7 is first manipulated to adjust the height of the horizontal shielding group 8 and its relative position to the vertical shielding group 9, thereby adjusting the width of the horizontal shielding group 8. Then, the horizontal shielding group 8 is opened to a specific width, creating an open space between the horizontal shielding groups 8 that is sufficient to cover the treatment area. The size and position of this open space are not fixed; the vertical range can be adjusted by controlling the extension and retraction of the vertical shielding group 9, and the horizontal range can be adjusted by controlling the retraction of the horizontal shielding group 8. This allows it to expose any area requiring treatment and any treatment area of ​​any shape from 1cm x 1cm to 5cm x 5cm.

[0023] Slide rails 11 are provided on both sides of the frame 6, arranged along the longitudinal direction of the frame 6, providing a stable track for the sliding of related components. Sliding blocks 12 are provided at both ends of the shielding rod 7. The shape of the sliding blocks 12 matches the slide rails 11, fitting perfectly into them. The sliding of the sliding blocks 12 within the slide rails 11 allows the shielding rod 7 to slide longitudinally within the frame 6. Simultaneously, the slide rails 11 also strictly limit the sliding direction of the shielding rod 7, ensuring it can only move smoothly longitudinally. Sliding blocks 21 are provided at both ends of the shielding plate 10 within the longitudinal shielding group 9. The sliding blocks 21 also fit the structure of the slide rails 11. The sliding blocks 21 slide within the slide rails 11. This fit not only guides the extension and retraction of the longitudinal shielding group 9 but also limits its extension and retraction within the frame 6 to longitudinal, ensuring the accuracy of its extension and retraction direction. The longitudinal shielding assembly 9 is connected to the frame 6 on one side and to the shielding rod 7 on the other side. This connection method allows the longitudinal shielding assembly 9 to extend and retract synchronously when the shielding rod 7 slides up and down. Each of the two shielding rods 7 has a slide rail 22 on one side, extending laterally along the shielding rod 7. The shielding panel 10 within the transverse shielding assembly 8 has sliding blocks 23 at both ends, matching the slide rail 22. The sliding blocks 23 slide within the slide rail 22, thus restricting the transverse shielding assembly 8 to only extend and retract laterally within the frame 6, ensuring that its extension and retraction direction meets adjustment requirements. A break area is provided in the middle of the transverse shielding assembly 8. This break area is crucial for creating an open space. By adjusting the degree of contraction of the transverse shielding assembly 8, the range of the break area changes accordingly, thus creating an open space that precisely covers the treatment area. In addition, all the shielding sheets 10 are set at an angle. This angled design can reduce the gap between adjacent shielding sheets 10 and enhance the overall light-blocking effect. Both sides of the shielding sheet 10 are provided with curved parts 13 in opposite directions. The shape of the curved parts 13 matches the side of the adjacent shielding sheets 10 and is specifically used to connect adjacent shielding sheets 10. This allows multiple shielding sheets 10 to be folded flexibly and fit tightly together after being connected, avoiding light-transmitting gaps.

[0024] Reference Figure 4 and Figure 7 The shielding rod 7 has a cylindrical cavity 14, and a rotating shaft 15 is rotatably mounted inside the cylindrical cavity 14. An adjusting knob 16 is fitted onto one end of the rotating shaft 15, with a portion of the adjusting knob 16 exposed outside the shielding rod 7. Multiple friction rings 17 are continuously fitted onto the rotating shaft 15, and a shielding winding 18 is fitted onto each friction ring 17. One end of the shielding winding 18 extends through the shielding rod 7 in the longitudinal direction of the shielding assembly 9. The cross-section of the shielding winding 18 is arc-shaped. The sliding friction between the rotating shaft 15 and the cylindrical cavity 14 is greater than the sliding friction between the friction rings 17 and the rotating shaft 15.

[0025] Specifically, the cylindrical cavity 14 extends along the length of the shielding rod 7, and its walls are polished to a smooth finish to reduce friction when the rotating shaft 15 rotates. Both ends are recessed inside the shielding rod 7 and will not penetrate its ends. The cylindrical cavity 14 houses the freely rotating shaft 15. The surface of the rotating shaft 15 can be treated with a wear-resistant finish to extend its service life. One end of the rotating shaft 15 is fitted with an adjustment knob 16, the surface of which can have anti-slip textures for easy gripping and application of force. A portion of the adjustment knob 16 protrudes from the shielding rod 7 for easy gripping and operation. By rotating the adjustment knob 16, the rotating shaft 15 can be easily rotated. Multiple tightly connected friction rings 17 are sequentially fitted onto the rotating shaft 15. The friction rings 17 are made of a wear-resistant material with a certain degree of elasticity, which can tightly fit the rotating shaft 15 and the shielding winding 18. The shielding winding 18 is wound around the friction rings 17. The shielding winding 18 is made of a flexible material with strong light-blocking properties, and one end of it extends out of the shielding rod 7 in the direction of the longitudinal shielding group 9. The shielding rod 7 can slide up and down within the frame 6, and the cross-section of the shielding winding 18 is designed to be arc-shaped. This arc-shaped structure can disperse external forces when the shielding winding 18 extends, increase its own rigidity, and effectively prevent the extended shielding winding 18 from bending due to its own weight or slight contact, ensuring the accuracy of secondary shielding and ensuring that the shielding effect is not affected.

[0026] Reference Figure 7 A baffle 19 is provided at the end of the shielding winding 18 that extends out of the shielding rod 7, and the shielding rod 7 is provided with a groove 20 to accommodate the baffle 19. This is designed to prevent the end of the shielding winding 18 from retracting into the cylindrical cavity 14; and to prevent the shielding winding 18 from extending out of the non-open area of ​​the transverse shielding group 8.

[0027] Working principle of the invention: In actual operation, the position of the two shielding rods 7 is first manipulated, and their sliding motion is used to adjust the height of the horizontal shielding group 8 and its relative position to the vertical shielding group 9, thereby adjusting the width of the horizontal shielding group 8. Then, the horizontal shielding group 8 is opened to a specific width, creating an open space sufficient to cover the treatment area. The size and position of this open space are not fixed; the vertical range can be adjusted by controlling the extension and retraction of the vertical shielding group 9, and the horizontal range can be adjusted by controlling the retraction and retraction of the horizontal shielding group 8. This allows it to expose any area requiring treatment and any size treatment area. (Refer to...) Figure 8 Based on this, the shielding winding 18 can extend the shielding rod 7 to different lengths according to the actual shape of the treatment area, such as an irregular patchy area, so that the shielding winding 18 extends to the edge of the lesion, as shown in the reference. Figure 9(Alternatively, extend all of the shielding windings 18 and keep their ends flush, then push them back to the edge of the lesion.) Secondary shielding is performed on the rectangular open space formed by the transverse shielding group 8 and the longitudinal shielding group 9, meticulously filling in the difference between the rectangle and the shape of the treatment area, ensuring a perfect fit to the contour of the treatment area, making the treatment more targeted. When the treatment is complete and the shielding groups need to be reset, rotate the adjustment knob 16 to retract all the shielding windings 18 and wrap them around the friction ring 17.
