Description

Technical Field

[0001] This application relates to the field of vitiligo treatment technology, and in particular to a phototherapy device for treating vitiligo. Background Technology

[0002] As the name suggests, a vitiligo phototherapy device is an instrument that uses the principle of ultraviolet light therapy to treat vitiligo. Its principle is to irradiate the affected area with ultraviolet medium-wave (UVB) or long-wave (UVA) light to stimulate the recovery function of melanocytes, thereby promoting the regeneration of melanin granules in the skin; adjusting the body's immunity and neuroendocrine system, promoting blood circulation, and improving blood microcirculation, thus causing the patient's skin to change from red to dark red or dark brown, ultimately achieving normal skin color. The phototherapy device uses light of specific wavelengths (such as ultraviolet light, laser, etc.) to act on the affected skin area.

[0003] In existing technologies, traditional use often results in the light source continuously shining on the same location, thus affecting the performance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, where the light source tends to continuously illuminate the same position during traditional use, thus affecting the effectiveness of the treatment. Therefore, this invention proposes a phototherapy device for treating vitiligo.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A phototherapy device for treating vitiligo, comprising:

[0007] The base and the treatment table and light shield respectively set on top of the base;

[0008] The collection box is fixedly installed on one side of the treatment table;

[0009] The sponge layer is fixedly installed on the top of the treatment table;

[0010] The display screen is fixedly installed on the other side of the treatment table;

[0011] A fixation mechanism, located at the top of the base, is used to secure the patient.

[0012] The lamp adjustment mechanism, located on the top of the treatment table, is used to adjust the patient's treatment position.

[0013] The light-shielding mechanism is located on the top of the base.

[0014] Preferably, the fixing mechanism includes two support plates fixedly installed on one side of the light-shielding cover, and each of the two support plates is fixedly installed with a binding strap on one side, and each of the two binding straps is fixedly installed with Velcro.

[0015] Preferably, the lamp adjustment mechanism includes a groove 1 disposed inside the treatment table, a drive motor disposed on the inner wall of the groove 1, a screw fixedly mounted on the output shaft of the drive motor, and the screw being rotatably connected to the groove 1, a connecting block 1 being threadedly connected to the outer surface of the screw, and the screw being slidably connected to the groove 1.

[0016] Preferably, an irradiation block is fixedly installed on the top of the connecting block one, and the irradiation block is slidably connected to the treatment table. A rotating shaft is rotatably installed on the irradiation block. An electric motor is provided on the rear side of the irradiation block, and the output shaft of the electric motor is fixedly connected to the rotating shaft. A fixing block is fixedly installed on the outer surface of the rotating shaft, and an ultraviolet lamp is fixedly installed on one side of the fixing block. By irradiating the vitiligo area with ultraviolet light, the activity of tyrosinase can be effectively activated, the production of melanin can be accelerated, thereby improving the symptoms of vitiligo. At the same time, it can also induce a series of photobiological effects in the skin, regulate immune function, inhibit abnormal immune responses in vitiligo patients, and reduce damage to melanocytes.

[0017] Preferably, the light-shielding mechanism includes two grooves on the front and rear sides of the light-shielding cover, an installation groove is provided inside the light-shielding cover, a slot is provided inside the base, a spring plate is fixedly installed on the inner wall of the installation groove, and an inclined block is fixedly installed at the bottom of the spring plate.

[0018] Preferably, a threaded rod is rotatably mounted on the inner wall of the slot, and a connecting block two is threadedly connected to the outer surface of the threaded rod. A push plate is fixedly mounted on one side of the connecting block two, and both the connecting block two and the push plate are slidably connected to the slot.

[0019] Preferably, a first bevel gear is fixedly mounted on the outer surface of the threaded rod, the first bevel gear meshes with a second bevel gear, and a rotating rod is fixedly mounted on the second bevel gear.

[0020] Preferably, the rotating rod is rotatably connected to the slot, and a crank handle is fixedly installed on the outer surface of the rotating rod.

[0021] The beneficial effects of the phototherapy device for treating vitiligo described in this utility model are as follows:

[0022] Because of the fastening mechanism, two Velcro straps are attached to each other. The Velcro straps have a strong adhesive ability, which improves the comfort of the Velcro straps. They can come into direct contact with the skin, thus achieving both an aesthetically pleasing appearance and improved comfort, and can fix the patient's legs.

[0023] Because of the lamp adjustment mechanism, the irradiation block moves back and forth through the connecting block, and the irradiation block moves the fixed block, rotating shaft, motor and ultraviolet lamp back and forth. After moving to a certain position, the rotating shaft drives the fixed block and ultraviolet lamp to rotate together. It can be adjusted left and right according to the patient's position, and can also be adjusted at the angle according to the patient's position, which increases the flexibility of treatment. The position and angle of the treatment device can be adjusted at any time, which not only improves the treatment effect.

[0024] Because of the light-shielding mechanism, by manually turning the crank, the crank drives the rotating rod to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate, and the first bevel gear drives the threaded rod to rotate. During the rotation of the threaded rod, the connecting block and the push plate move upward. When the push plate moves upward, it can push the inclined block out, which will compress the spring plate, thereby allowing the light-shielding cover to be taken out. This can prevent light leakage and ensure that the light can be concentrated on the affected area.

[0025] This invention, in traditional use, can illuminate different positions with a light source, thus improving the effectiveness of use. Attached Figure Description
