[0002] Ultraviolet phototherapy is a physical therapy technology that uses ultraviolet light to irradiate the human body to prevent and treat diseases. This instrument has significant therapeutic effects on skin diseases such as vitiligo and psoriasis. Ultraviolet phototherapy emits medium-wave ultraviolet light with a wavelength of 311nm, most of which is absorbed by the epidermal tissue, and has significant biological effects on the skin and other tissues. Ultraviolet light has good drying, sterilization, and anti-inflammatory effects, and has a direct killing effect on bacteria or viruses in superficial tissues. At the same time, it also accelerates blood circulation, relieves pain, and promotes epithelial regeneration.

[0003] When using an ultraviolet phototherapy device to treat a patient's affected area, there may be a situation where the ultraviolet radiation range is large. When ultraviolet radiation shines on the patient's normal skin, it can easily accelerate the aging of the skin and also easily trigger inflammatory reactions on the skin, which can affect the use of the ultraviolet phototherapy device.

[0004] Therefore, this utility model provides a light-shielding structure for a phototherapy device. Utility Model Content

[0009] Preferably, a guide block is fixedly connected to the side wall of the light-shielding plate; the guide block is slidably connected to the inside of the light-shielding cover; so that the light-shielding cover tilts less during the sliding process, making the light-shielding plate more stable when sliding.

[0010] Preferably, a positioning block is fixedly connected to the side wall of the threaded rod; the positioning block is rotatably connected to the inside of the sliding frame; making the positioning block more stable during rotation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] like Figures 1 to 4 As shown in the embodiment of this utility model, a light-shielding structure for a phototherapy device includes a phototherapy device body 1; a support arm 2 is fixedly connected to the side wall of the phototherapy device body 1; a light shield 3 is fixedly connected to the end of the support arm 2 away from the phototherapy device body 1; an ultraviolet lamp 4 is installed inside the light shield 3; a support frame 5 is fixedly connected to the bottom of the light shield 3; two sliding frames 6 are fixedly connected to the side wall of the light shield 3, and the two sliding frames 6 are arranged on two adjacent side walls of the corresponding light shield 3; the two sliding frames 6 are staggered; a light-shielding plate 7 is slidably connected inside the sliding frame 6; a threaded rod 8 is rotatably connected inside the sliding frame 6; the light-shielding plate 7 and the threaded rod 8 are threadedly connected; a drive mechanism is fixedly connected to the side wall of the sliding frame 6. Motor 9; The threaded rod 8 is fixedly connected to the output end of the drive motor 9; During operation, when phototherapy is needed for a patient, the patient's affected limb can be placed inside the support frame 5, and then the drive motor 9 can be started, causing the drive motor 9 to drive the threaded rod 8 to rotate. Through the threaded engagement between the threaded rod 8 and the light shield 7, the light shield 7 is moved inside the sliding frame 6, thereby blocking the light emitted by the ultraviolet lamp 4 through the two light shields 7. This makes it easier to control the range of light and effectively solves the problem that when ultraviolet light shines on the patient's normal skin, it can easily accelerate the aging of the human skin and also easily cause inflammatory reactions on the skin, which can affect the use of the ultraviolet phototherapy device.

[0024] like Figures 1 to 2As shown, a light-blocking curtain 10 is fixedly connected inside the light-blocking cover 3; the light-blocking curtain 10 is provided at both ends of the light-blocking cover 3; during operation, when irradiating the patient's affected area, by setting the light-blocking curtain 10 at the end of the light-blocking cover 3, the irradiated light can be blocked, effectively preventing the light from scattering to the outside and easily affecting the rest of the patient's skin.

[0025] like Figure 2 As shown, a support pad 11 is fixedly connected inside the support frame 5; the shape and size of the support pad 11 are correspondingly set to the shape and size of the support frame 5; during operation, when the patient's affected limb is placed inside the support frame 5, by setting the support pad 11 inside the support frame 5, the contact area between the patient's affected limb and the support frame 5 can be increased, thereby making the affected limb more stable when placed inside the support frame 5, and at the same time making the patient more comfortable.

[0026] like Figures 3 to 4 As shown, a guide block 12 is fixedly connected to the side wall of the light-shielding plate 7; the guide block 12 is slidably connected to the inside of the light-shielding cover 3; during operation, when the light-shielding plate 7 slides inside the light-shielding cover 3, the sliding of the guide block 12 is restricted by the light-shielding cover 3, so that the light-shielding cover 3 tilts less during the sliding process, making the light-shielding plate 7 more stable when sliding.

[0027] like Figures 3 to 4 As shown, a positioning block 13 is fixedly connected to the side wall of the threaded rod 8; the positioning block 13 is rotatably connected to the inside of the sliding frame 6; during operation, when the threaded rod 8 is driven to rotate by the drive motor 9, the rotation of the positioning block 13 is restricted by the sliding frame 6, which makes the positioning block 13 more stable during rotation.

[0028] like Figures 3 to 4 As shown, a plurality of balls 14 are provided between the sliding frame 6 and the positioning block 13; the sidewalls of the balls 14 are in contact with the sidewalls of both the sliding frame 6 and the positioning block 13; during operation, when the positioning block 13 rotates inside the sliding frame 6, the balls 14 provided between the sliding frame 6 and the positioning block 13 can change the sliding friction between the sliding frame 6 and the positioning block 13 into rolling friction, thereby reducing the frictional force between the sliding frame 6 and the positioning block 13 and thus reducing the wear between the sliding frame 6 and the positioning block 13.

[0029] When phototherapy is needed, the patient's affected limb can be placed inside the support frame 5. Then, the drive motor 9 can be started, causing the threaded rod 8 to rotate. Through the threaded engagement between the threaded rod 8 and the light-shielding plate 7, the light-shielding plate 7 moves inside the sliding frame 6. This allows the light emitted by the ultraviolet lamp 4 to be blocked by the two light-shielding plates 7, making it easier to control the range of light. This effectively solves the problem that when ultraviolet light shines on the patient's normal skin, it can accelerate the aging of the skin and easily cause inflammatory reactions, which can affect the use of the ultraviolet phototherapy device.

[0030] When irradiating the patient's affected area, a light-blocking curtain 10 is installed at the end of the light-blocking shield 3 to block the irradiated light, effectively preventing the light from escaping to the outside and potentially affecting the rest of the patient's skin.

[0031] When the patient's affected limb is placed inside the support frame 5, the support pad 11 inside the support frame 5 increases the contact area between the patient's affected limb and the support frame 5, making the affected limb more stable inside the support frame 5 and increasing the patient's comfort.

[0032] When the light shield 7 slides inside the light shield 3, the sliding of the guide block 12 is restricted by the light shield 3, so that the light shield 3 tilts less during the sliding process, making the light shield 7 more stable when sliding.

[0033] When the threaded rod 8 is driven to rotate by the drive motor 9, the rotation of the positioning block 13 is restricted by the sliding frame 6, which makes the positioning block 13 more stable during rotation.

[0034] When the positioning block 13 rotates inside the sliding frame 6, the ball bearing 14 between the sliding frame 6 and the positioning block 13 can change the sliding friction between the sliding frame 6 and the positioning block 13 into rolling friction, which reduces the friction between the sliding frame 6 and the positioning block 13 and thus reduces the wear between the sliding frame 6 and the positioning block 13.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
