Description

Technical Field

[0001] The invention belongs to the technical field of ultraviolet therapeutic devices, and in particular relates to a wearable ultraviolet therapeutic device. Background Art

[0002] Vitamin D is an essential nutrient for maintaining the life of higher animals and is vital for bone health. According to research, the lack of vitamin D in residents is closely related to modern lifestyles, such as insufficient sunlight, an unreasonable diet, and reduced outdoor activities. Although vitamin D can be supplemented through sun exposure and food, it is difficult to obtain vitamin D naturally due to the weakening of ultraviolet rays, the popularization of sun protection measures, and the short sunshine time in winter, so it is particularly important to increase the level of vitamin D in the body.

[0003] Existing phototherapy technology mainly uses ultraviolet light with a wavelength of 280-320nm (UVB) to improve vitamin D deficiency by promoting metabolism of substances in the body and the synthesis of vitamin D.

[0012] The auxiliary shoulder strap passes through four connecting ears of the upper shell and is adjusted in tightness by Velcro to fit users of different body shapes.

[0013] The middle isolation plate is fixed on the aluminum substrate by screws and is used to isolate the ultraviolet LED lamp beads and the light homogenizing plate.

[0029] In this embodiment, the ultraviolet therapeutic device is mainly used for the treatment of back skin diseases, and a wearable design is used to achieve convenient and uniform ultraviolet irradiation. Figure 1As shown, the therapeutic device includes a phototherapy module 1, a power supply 2, a controller 3, a connecting line 4 and an auxiliary strap 5. The phototherapy module 1 is fixed to the back of the human body through the auxiliary strap 5 made of silicone material, and the controller 3 is connected to the power supply 2 composed of a lithium-ion battery pack through the connecting line 4. The controller 3 is provided with a touch interface, which can set the irradiation time (adjustable from 10 to 20 minutes, stepping 5 minutes) and the power level (10 to 20 μW / cm 2 , 5μW / cm 2 step), and control the output intensity of the UV LED through PWM dimming.

[0030] Further, if Figure 2-5 As shown, the phototherapy module 1 adopts a layered design: Shell structure: The upper shell 1-1 and the lower shell 1-5 are both made of medical grade silicone injection molding, with a thickness of 2mm, and are flexible to fit the curve of the human body. Fixing method: Connected by several groups of mushroom columns 1-5-2: The cylindrical protrusion (diameter 3mm, height 5mm) of the lower shell 1-5 passes through the corresponding hole 1-1-3 of the upper shell 1-1, and an interference fit is formed by the elasticity of silicone. An elliptical head 1-1-4 and an elliptical groove 1-5-3 are set at the edge, and medical silicone glue is used for bonding to ensure sealing.

[0031] Furthermore, there are 20 aluminum substrates 1-3, each with a size of 45×45mm, which are positioned by the card slot 1-5-1 of the lower shell 1-5, with a spacing of 5mm between adjacent boards, and are connected in series using flexible FPC lines. Each aluminum substrate is welded with 12 UVB LED lamp beads (model PB-B2SHD, power 2mW) with a peak wavelength of 297nm, and the irradiation area is 320cm 2 , the maximum irradiation dose is 24mJ / cm 2 The dose is much smaller than the standard erythema dose of 100 J / m 2 (GB / T20150-2023 Erythema benchmark action spectrum and standard erythema dose GB / T21005-2007 Ultraviolet erythema effect reference spectrum, standard erythema dose and ultraviolet index). The light homogenizing plate 1-2 is made of 2mm thick PTFE sheet with a transmittance of 15-30%, embedded in 20 rectangular grooves 1-1-2 (size 40×40mm) of the upper shell 1-1, and the uniformity of ultraviolet radiation intensity is not more than ±10%.

[0032] Furthermore, the upper shell 1-1 is provided with an array of heat dissipation holes 1-1-5 (aperture 1mm, spacing 3mm), which, combined with the thermal conductivity of the aluminum substrate 1-3 of 238W / m·K, stabilize the operating temperature below 40°C.

[0033] Furthermore, the middle isolation plate 1-4 is a 10 mm thick ABS plate, which is fixed to the aluminum substrate 1-3 by M2 screws and maintains a distance of 10 mm from the light homogenizing plate 1-2. This distance ensures the homogenization of light.

[0034] Furthermore, the auxiliary strap 5 is made of a 50mm wide silicone belt, which passes through the connecting ears 1-1-1 (annular structure with an inner diameter of 6mm) at the four corners of the upper shell 1-1, and the length is adjusted by Velcro (suitable for people with a chest circumference of 80-120cm). The inner side of the auxiliary strap 5 is provided with silicone anti-slip patterns, and the pressure sensor monitors the fit in real time. When the pressure is less than 50N, the controller will sound an alarm.

[0035] Furthermore, the power supply 2 is a 3S lithium-ion battery pack (7.2V / 5000mAh), which is charged via the USB-C interface and has a battery life of 4 hours. The controller 3 has a built-in STM32F103 main control, with temperature protection (automatic power off at >45°C) and countdown function, and a buzzer prompts after the treatment is completed.

[0036] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the protection scope of the present invention.
