Description

Technical Field

[0001] The present 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 life in higher animals and is crucial for bone health. Research suggests that vitamin D deficiency is closely linked to modern lifestyles, such as insufficient sunlight exposure, an unhealthy diet, and reduced outdoor activity. While vitamin D can be supplemented through sunlight and dietary intake, naturally occurring vitamin D is difficult to obtain due to reduced UV radiation, widespread sun protection measures, and shorter daylight hours in winter. Therefore, boosting vitamin D levels is particularly important.

[0003] Existing phototherapy technologies primarily utilize ultraviolet light (UVB) with a wavelength of 280-320 nm to improve vitamin D deficiency by promoting metabolism and vitamin D synthesis in the body. However, such phototherapy devices are typically bulky and inconvenient to use in daily life, limiting their popularity and convenience. Summary of the Invention

[0011] The upper shell is provided with a plurality of heat dissipation holes for dissipating the heat generated when the aluminum substrate is working.

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

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

[0014] The power source is a lithium-ion battery pack, which is connected to the controller via a connecting line.

[0015] The upper shell is provided with an elliptical head, and the lower shell is provided with a corresponding elliptical groove. The elliptical head and the elliptical groove are bonded and fixed by silicone glue.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all the embodiments. These descriptions are only to further illustrate the features and advantages of the present invention, rather than to limit the claims of the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0029] In this embodiment, the ultraviolet therapy device is mainly used for the treatment of back skin diseases, and realizes convenient and uniform ultraviolet radiation through a wearable design. Figure 1As shown in the figure, 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, in steps of 5 minutes) and the power level (10 to 20 μW / cm 2 , 5μW / cm 2 step), and controls 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 injection-molded with medical-grade silicone, with a thickness of 2mm and flexibility to conform to the curves of the human body. Fixing method: Connected by several groups of mushroom pillars 1-5-2: The cylindrical protrusions (3mm diameter, 5mm height) of the lower shell 1-5 pass through the corresponding holes 1-1-3 in the upper shell 1-1, forming an interference fit using the elasticity of the silicone. The edges are provided with elliptical heads 1-1-4 and elliptical grooves 1-5-3, bonded with medical silicone glue to ensure a tight seal.

[0031] Furthermore, there are 20 aluminum substrates 1-3, each measuring 45×45mm. They are positioned by the slots 1-5-1 of the lower shell 1-5, with a spacing of 5mm between adjacent panels. They are connected in series using flexible FPC circuits. Each aluminum substrate is welded with 12 UVB LED lamp beads (model PB-B2SHD, power 2mW) with a peak wavelength of 297nm, irradiating an area of 320cm. 2 , the maximum irradiation dose is 24mJ / cm 2 , its 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 homogenizer 1-2 is made of 2mm thick PTFE sheet with a transmittance of 15-30%. It is embedded in 20 rectangular slots 1-1-2 (size 40×40mm) of the upper housing 1-1. The uniformity of the ultraviolet radiation intensity is no 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 base plate 1-3 by M2 screws and maintains a distance of 10 mm from the light homogenizing plate 1-2. This distance ensures the uniformity of light.

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

[0035] Furthermore, Power Supply 2 is a 3S lithium-ion battery pack (7.2V / 5000mAh), which is charged via a USB-C port and has a battery life of up to 4 hours. Controller 3 has a built-in STM32F103 main control unit, with temperature protection (automatic power off at >45°C) and a countdown function, with a beeping alarm when treatment is completed.

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