Description

Technical Field

[0001] The invention belongs to the technical field of ultraviolet therapy, and in particular relates to a chair-type ultraviolet therapy device. Background Art

[0002] Vitamin D, as an essential nutrient for maintaining the life of higher animals, plays a key role in bone health, calcium and phosphorus metabolism, and immune system regulation. However, clinical studies have shown that vitamin D deficiency is extremely common in the Chinese population. A survey covering 2,173 Chinese residents showed that 94.6% of individuals had varying degrees of vitamin D deficiency, a phenomenon closely related to modern lifestyles, working environments, and geographical climates. Although sunlight exposure and dietary supplements are the main sources of vitamin D, the reduction in outdoor activities and long-term indoor office work during the urbanization process have led to insufficient sunlight. In addition, the short sunshine hours and weak ultraviolet light intensity in winter make it difficult to meet the demand by supplementing vitamin D through natural sunlight.

[0003] Currently, ultraviolet light therapy has received widespread attention as an important means of artificially supplementing vitamin D. Traditional ultraviolet light therapy equipment mostly adopts a vertical or horizontal structure, and has the following technical defects: First, the equipment structure is complex and bulky, making it difficult to adapt to the use scenarios of homes or small medical facilities; second, the light therapy process lacks ergonomic design, and users cannot adjust their body position according to their needs, resulting in poor comfort; third, existing equipment mostly uses a broad-spectrum ultraviolet light source, the irradiation wavelength is not accurate enough, and there is a lack of real-time intensity monitoring and closed-loop control, which poses the risk of skin damage caused by excessive exposure; fourth, when used in winter, the low temperature of the light-emitting surface leads to a poor user experience, and the equipment is not easy to disinfect, which may cause cross-infection. In addition, traditional light therapy equipment mostly relies on external power supplies, which has limited mobility and cannot meet the user's needs for flexible use.

[0004] While some improved UV phototherapy devices exist in the existing technology to address these issues, they still haven't fully addressed the coordinated optimization of portability, comfort, safety, and ease of use. Designing a phototherapy device that integrates an ergonomic chair structure, a precise narrow-spectrum UV light source, and intelligent temperature control and irradiation monitoring systems has become a pressing technical challenge in this field.

DETAILED DESCRIPTION

[0023] 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.

[0024] 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.

[0025] 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.

[0026] In this embodiment, if Figure 1 As shown, a chair-type ultraviolet therapy device includes a chair body 2, an electric push rod and a functional iron frame 8, a phototherapy module 1, a hand controller, and a touch screen 3. The chair body 2 is composed of a wooden structure, a decorative shell 2-1, and a leather upholstery. The phototherapy module 1 is mounted on the backrest of the phototherapy chair body 2 and is electrically connected to the hand controller and touch screen 3. The electric push rod and functional iron frame 8 are mounted on the bottom of the chair body 2, providing power and angle changes for the backrest and leg rest to expand and retract. The touch screen 3 is embedded in the armrest panel on the right side of the chair body 2. The touch screen 3 controls the start and end of phototherapy and the irradiation time of the phototherapy module. Four universal casters 7 are set at the bottom of the chair body 2 for easy transportation.

[0027] Furthermore, the phototherapy module 1 is provided with an ultraviolet LED lamp bead 1-6-1, a frame 1-4, a mirror-polished aluminum foil 1-10, a light board support plate 1-5, a light box bottom plate 1-8, a pressure plate 1-1, a circuit board 1-6, a control board 1-9, a lithium battery 1-7, a CBC board 1-3 and a polytetrafluoroethylene film 1-2. The circuit board 1-6 is mounted on the light board support plate 1-5, the ultraviolet LED lamp bead 1-6-1 is arranged on the circuit board 1-6, the light box bottom plate 1-8 is mounted on the bottom of the frame 1-4, the pressure plate 1-1 fixes the polytetrafluoroethylene film 1-2 and the CBC board 1-3 to the top of the frame 1-4, and the polytetrafluoroethylene film The thickness of 1-2 is 0.1-1mm. The polytetrafluoroethylene film 1-2 has a certain transmittance to ultraviolet light with a peak wavelength of 297±3nm. The transmittance is different for different thicknesses. Because of this, the refraction and reflection characteristics of the material are utilized, and the polytetrafluoroethylene film 1-2 has good light uniformity. The CBC plate 1-3 and the polytetrafluoroethylene film 1-2 together form the light-emitting surface. The frame 1-4 and the surface of the lamp board support plate 1-5 are pasted with mirror-polished aluminum foil 1-10. Such a light box structure can ensure the uniformity of the light emission of the lamp beads. The LED point light source is refracted and reflected to become a surface light source. The uniformity of the surface light source is within 10%. The ultraviolet LED lamp bead 1-6-1 adopts a narrow-spectrum ultraviolet light source with a peak wavelength of 297±3nm. The lithium battery 1-7 provides power for the phototherapy module 1. Platen 1-1 is equipped with a UV sensor 1-12, model CLUSVTGAF1T-IJ. This sensor monitors the UV intensity in real time and feeds the sensor signal back to the control system. If the UV intensity exceeds or falls below a set value, the system adjusts the current until the intensity returns to the set value, forming a closed-loop control system. Platen 1-1 is also equipped with a temperature sensor 1-11, which monitors the temperature of the light-emitting surface in real time.

[0028] Furthermore, UV LED 1-6-1 utilizes a narrow-spectrum UV light source with a peak wavelength of 297±3nm and 850nm or 940nm infrared LED 1-6-2. Infrared LED 1-6-2 primarily heats the light-emitting surface. Because treatment requires bare skin, the surface temperature of the light-emitting surface can be low and feel cold in winter. To address this, prior to treatment, infrared LED 1-6-2 is first activated to heat the light-emitting surface to 20-30°C. UV LED 1-6-1 is then activated for treatment, enhancing user comfort. Infrared LED 1-6-2 and UV LED 1-6-1 are spaced apart.

[0029] Furthermore, the hand controller is divided into a left armrest hand controller 6 and a right armrest hand controller 4. The right armrest hand controller 4 is equipped with a charging switch 4-2 and a power button 4-1. When the charging switch 4-2 is pressed, the lithium battery 1-7 built into the light therapy module is charged. The power button 4-1 is used to control the power on and off of the light therapy module 2. The left armrest hand controller 6 is equipped with an expand button 6-2 and a retract button 6-1 to control the expansion and retraction of the chair backrest and leg rest. The bottom of the chair body 2 is provided with an electric push rod and a functional iron frame 8. The functional iron frame is driven by the electric push rod. When the electric push rod moves forward, the backrest and leg rest are expanded together. When the electric push rod moves backward, the backrest and leg rest are retracted together. In the retracted state, the leg rest is 90 degrees to the horizontal plane and the backrest is 115 degrees to the horizontal plane. In the expanded state, the leg rest is 180 degrees to the horizontal plane and the backrest is 150 degrees to the horizontal plane. By adjusting the backrest and leg rest, the user can enjoy light therapy in a more comfortable posture, enhancing the user experience.

[0030] Furthermore, a purple light strip 5 is provided on the inside of the armrest, which is electrically connected to the control board 1-9. 4*10 grooves are provided on the inside and outside of the armrest, which match the 5*10mm side-emitting silicone light strip. During phototherapy, the purple light is always on. A blue light strip 5 is provided on the outside of the armrest, and the blue light is always on when preparing for and ending phototherapy.

[0031] The recommended treatment method of the present invention is irradiation five times a week, each time for 20 minutes, with an irradiation intensity of <8μW / cm², which is much lower than the minimum erythema dose of the human body, ensuring the safety of the treatment.

[0032] Since users need to expose their skin for irradiation, in order to facilitate rapid disinfection of different users and prevent cross infection, a replaceable disposable non-woven fabric is set on the back. The middle of the non-woven fabric is hollowed out to expose the phototherapy area. The non-woven fabric is connected by Velcro at the top of the backrest, which can be replaced quickly and conveniently.

[0033] 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.
