Description

Technical Field

[0001] The present application relates to an LED308 phototherapy device, and in particular to an LED308 pen-type phototherapy device, which belongs to the field of ultraviolet phototherapy technology. Background Art

[0002] It is well known that the commonly used treatments for vitiligo and psoriasis include drug therapy, physical therapy and surgical treatment, among which physical therapy is the most widely used, and the most commonly used physical therapy is ultraviolet irradiation with a wavelength of 308nm.

[0003] At present, 308nm UVB phototherapy on the market is divided into three categories according to the light source: 308nm excimer laser, 308nm quasi-spectrography, and 308nm LED light. The principle of 308nm excimer light / laser is that inert gas atoms produce high-energy ultraviolet light (excimer light) under the excitation of excimers, and 308nm LED light uses UVB LED to emit ultraviolet light with a peak wavelength of 308nm. 308nm excimer laser treatment of vitiligo and psoriasis has been clinically proven to be safe and effective. The peak wavelength of 308nm LED is almost the same as that of 308nm excimer lamp, so the effect is the same in clinical treatment. Compared with 308 excimer light and 308 excimer laser, LED 308 has obvious advantages in terms of safety of use, light source life, consumables, maintenance, and impact on the environment.

[0004] In the related technology, LED308 ultraviolet light therapy devices are often used for the precise treatment of vitiligo and psoriasis in small areas such as hands and feet, among which miniaturized products are widely in demand due to their portability. However, currently known portable LED308 ultraviolet light therapy devices, such as CN210992644U, a portable ultraviolet light therapy device, although portable, are limited to use in fixed scenarios such as homes or medical institutions in terms of both appearance, size and performance, and cannot be used anytime, anywhere, and are not suitable for more temporary and non-specific scenarios.

[0005] At the same time, for patients in the early stages of the disease, children with smaller physiques, and special parts such as the lower abdomen and groin, since the affected area is very small, during treatment, when the irradiated area is larger than the area of ​​the treated part, it will damage the surrounding normal skin, posing a safety issue. When shielding measures are taken to assist the operation, it will become cumbersome and affect the treatment efficiency. Utility Model Content

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] In the related art, portable phototherapy devices, such as CN210992644U and CN214807927U, generally set up a light source, heat dissipation, part of the control circuit and the display screen together as a phototherapy head. The phototherapy devices other than the phototherapy head are mostly handheld shells, which need to be used as carriers to set the main control circuit and power control circuit, charging or replaceable power supply structure, operation buttons, switch buttons, etc. For the whole machine, the overall structure is not compact enough, and the volume cannot achieve the effect of carrying it with you and taking it whenever you want. In addition, the interface for display and / or operation is relatively small, and the configuration on a miniaturized product affects the user experience. Furthermore, with the miniaturized design of the product, in terms of function, it is inevitable that the optimal configuration of the irradiation intensity and the heat dissipation effect cannot be taken into account.

[0050] Based on the above-mentioned technical problems, the embodiment of the present application provides a LED308 pen-type phototherapy device, which can be carried with you and used anytime and anywhere, and can accurately treat difficult areas, avoid irradiation of normal skin, and make treatment convenient and efficient.

[0051] Reference Figures 1 to 5 As shown, the LED308 pen-type phototherapy device includes a pen-shaped housing 10 and an LED light source assembly 20, a heat dissipation assembly 30, a built-in power supply assembly 40, a control assembly 50 and a display assembly 60 arranged in the pen-shaped housing 10;

[0052] The pen-shaped housing 10 is in a strip shape as a whole and has a closed end and a light-emitting end at both ends in the length direction. The pen-shaped housing 10 also forms a display plane portion and an operation curved portion at two opposite sides perpendicular to the length direction.

[0053] The LED light source assembly 20, the heat dissipation assembly 30 and the built-in power supply assembly 40 are sequentially arranged along the length direction of the pen-shaped housing 10, and correspond to one side of the operating curved surface; one end of the LED light source assembly 20 is connected to the light emitting end, and the other end thereof is connected to the heat dissipation assembly 30;

[0054] The display assembly 60 and the control assembly 50 are stacked on one side of the heat dissipation assembly 30 and the built-in power supply assembly 40, and together correspond to one side of the display plane portion.

[0055] The LED308 pen-type phototherapy device provided in the present application is provided with a compact pen-shaped shell 10, and using it as a carrier, a light-emitting end is provided at one end of the length, and the main components are centrally arranged in the pen-shaped shell 10 outside the light-emitting end; specifically, a display plane portion and an operating curved portion are provided along the height direction, and a large-area screen display component 60 and an integrated control component 50 are stacked on the display plane portion, and then the LED light source component 20, the heat dissipation component 30, and the built-in power supply component 40 are compactly arranged along the length direction in the inner cavity of the pen-shaped shell 10 corresponding to the operating curved portion; thereby, the finished product of the present application can be carried with you and used anytime and anywhere, and can accurately treat difficult areas, such as small-area early-stage vitiligo in children or difficult areas such as the armpits and groin, without the need for additional shielding operations, and the affected area can be accurately treated, avoiding exposure to normal skin.

[0056] The specific shape of the pen-shaped housing 10 is not limited. For example, in the embodiment of the present application, the pen-shaped housing 10 can be similar to the shape of an existing "point reading pen" with a large screen display, so as to meet the requirements of being carried in a bag or pocket. The LED308 pen-type phototherapy device in the embodiment of the present application focuses on the compact and portable characteristics of the product in terms of overall design, and also realizes the firmness and drop resistance of the structural components. At the same time, the uniformity of the overall weight of the device is taken into consideration, and the convenience and comfort of hand-held irradiation and the convenience of repairing and replacing parts are fully taken into consideration.

[0057] Reference Figure 1-4 In a possible implementation, the closed end is a semicircular head structure; the plane where the light-emitting end is located is set at an angle to the longitudinal plane of the pen-shaped shell 10; and the cross-sectional shape of the operating curved surface is "U"-shaped.

[0058] The angle between the light-emitting end and the pen-shaped housing 10 is set so that the light-emitting port 11-1 is inclined at a certain angle. Figure 2 The light outlet 11 - 1 adopts an inclined surface to ensure close contact with the skin. When in use, the light outlet 11 - 1 can be easily aligned with the treatment area, and will not cause fatigue when used for a long time.

[0059] The semicircular design of the closed end helps to reduce the size of the product while creating a unique appearance; the "U" shape of the operating curve can increase the installation space while improving the handheld operating area and comfort, while also beautifying the appearance.

[0060] Reference Figure 5In a possible implementation, the pen-shaped shell 10 is mainly composed of a front shell 11, an upper shell 12 and a lower shell 13; a light outlet 11-1 is provided at the center of the front shell 11, constituting a light outlet end; the upper shell 12 is provided with a display window 12-1 for installing a screen display component 60 and has an upper shell cavity 121 for accommodating a control component 50, constituting a display plane portion; the lower shell 13 is provided with a lower shell cavity 131 for accommodating a heat dissipation component 30 and a built-in power supply component 40, constituting an operating curved surface portion.

[0061] In order to meet the requirements of light weight, firmness and drop resistance, the material of the front shell 11, the upper shell 12 and the lower shell 13 can all be ABS. In order to obtain good anti-slip and wear-resistant properties, a surface with an oily touch can be further provided.

[0062] The light outlet 11-1 directly forms the treatment area, and the light outlet end formed on the front shell 11 can obtain a more compact and precise treatment effect. It can be achieved by simply touching the affected area, making the treatment convenient and efficient. The display plane portion is composed of a screen display component 60 and a control component 50 mounted in the upper shell cavity 121, realizing a large interface display, overcoming the shortcomings of limited display and operation of small phototherapy products, and improving the user experience. The operating curved surface portion is composed of a heat dissipation component 30 and a built-in power supply component 40 mounted in the lower shell cavity 131, realizing a compact layout of functional components, which is conducive to reducing the product volume and further improving the product portability.

[0063] Reference Figure 6-10 In a possible implementation, the shape of the light outlet 11-1 is rectangular; a plurality of contact sensors 111 are evenly distributed around the light outlet 11-1, each contact sensor 111 is independently connected to the input end of the control component 50, and the output end of the control component 50 is commonly associated with the LED light source component 20; a light-transmitting glass 112 is installed on the inner side of the light outlet 11-1; a sealing ring 113 is provided between the light-transmitting glass 112 and the LED light source component 20.

[0064] The shape of the light outlet 11-1 is designed to be rectangular, so as to fit the LED light source assembly 20 arranged in a matrix at the end of the small cross section of the pen-shaped housing 10, thereby outputting ultraviolet light with both small diameter and high energy. Furthermore, in some models, the light outlet 11-1 with a rectangular light spot shape can be specifically set, and in other models, the light outlet 11-1 with a square light spot shape can also be specifically set.

[0065] In this embodiment, the light-transmitting glass 112 mainly plays the role of protecting the light source, and its material can be quartz glass. Further preferably, the quartz glass has a thickness of 1.5 mm and a distance of 1 mm from the surface of the light source. In order to achieve the effect of strengthening protection, a sealing ring 113 needs to be placed between the glass and the light source, and the sealing ring 113 can also play a certain decorative role.

[0066] In order to facilitate the operator to find the treatment site during irradiation, a light outlet 11-1 is formed on the shell of the front shell 11. Specifically, the inner edge of the shell corresponds to the light outlet 11-1, so the shape of the inner edge is rectangular, such as a rectangle with a size of 19.5×13mm or a square with a size of 16×16mm, and the outer edge of the shell corresponds to the outer contour shape of the entire light outlet, which can be a rectangle or other shapes, such as a circle.

[0067] In a specific implementation, the light outlet 11 - 1 is preferably designed to protrude 1 to 2 mm from the shell surface, and the protruding portion is made of a transparent material that is not transparent to ultraviolet rays, thereby minimizing the size of the phototherapy head while ensuring that the operator can easily aim at the irradiated area.

[0068] Multiple contact sensors 111 are used to trigger the light source. Only when the light emitting end fully contacts the affected skin, that is, multiple contacts built around the light outlet 11-1 by multiple contact sensors 111 are triggered, will the irradiation treatment be started. This avoids erroneous operation caused by turning on the light source when the light outlet 11-1 is partially contacted, and safety is improved.

[0069] In one possible implementation, a table 122 for docking the display assembly 60 is provided around the upper periphery of the display window 12-1, and the upper shell cavity 121 is located at the lower part of the display window 12-1. The display assembly 60 and the control assembly 50 are respectively connected to the outer surface and inner surface of the table 122.

[0070] In this embodiment, the screen display component 60 may include a glass cover plate, a touch sensor chip and a liquid crystal display screen. When assembled, the glass cover plate of the screen display component 60 can be fixed to the table 122 by adhesive, so as to be flush with the upper surface of the upper shell 12, so as to maximize the coverage on the surface of the upper shell 12, and build a visual and convenient human-computer interaction interface. A screen film 61 can also be provided on the outer surface of the glass cover plate. As a feasible solution, the touch sensor chip and the liquid crystal display screen are consistent with the size of the display window 12-1, and the two are arranged in the display window 12-1 in an overlapping manner. The liquid crystal display screen is directly arranged in close contact with the control component 50 in the upper cavity, so that full-screen display and touch are possible. As another feasible solution, the touch sensor chip and the liquid crystal display screen are arranged in different areas in the display window 12-1, and are arranged in close contact with the control component 50 in the upper cavity, so that partial display and partial touch are possible. Further, the liquid crystal display screen can be selected as a TFT liquid crystal screen, and the screen size can be selected according to the appearance design effect of the product during design. For example, when partially displayed, it can be set to 0.96 inches. In this embodiment, the control component 50 may be a main control board that centrally provides a shutdown low-power circuit, a skin detection circuit, a temperature acquisition circuit, a battery charging circuit, an LED drive circuit, and an acceleration detection circuit.

[0071] Reference Figure 11-15 In a possible implementation, a connecting sheet metal part 14 is provided between the upper shell 12 and the lower shell 13 to reinforce the assembly of the upper shell 12 and the lower shell 13 and to maintain the spatial independence of the upper shell cavity 121 and the lower shell cavity 131;

[0072] The connecting sheet metal 14 includes a supporting sheet metal 141 limited between the upper shell 12 and the lower shell 13. The supporting sheet metal 141 is provided with at least a first connecting end 1411 and a second connecting end 1412 facing the upper shell 12 and the lower shell 13 respectively. The first connecting end 1411 is used to fix the control component 50 to the upper shell 12 through a first fastener, and the second connecting end 1412 is used to fix the control component 50 to the upper shell 12 through a second fastener.

[0073] Exemplarily, the overall shape of the supporting sheet metal 141 of the connecting sheet metal 14 can be "Π"-shaped, and the first connecting end 1411 can be arranged at the two free ends of the "Π"-shape, for example, it can be formed by extending and then bending, and the second connecting end 1412 can be arranged in the middle of the closed end of the "Π"-shape, for example, the bent plate connector can be installed by one-piece molding or fixed connection.

[0074] Reference Figure 11-15 and Figure 18-20In a possible implementation, the lower shell 13 is provided with a front opening 131-1 and a top opening 131-2 both connected to the lower shell cavity 131, which are respectively used to connect the front shell 11 and the upper shell 12; a hand-held concave arc 132 is provided in the middle position of the outer side of the lower shell 13, and an operation key opening 132-1 and an anti-slip convex pattern 1321 are respectively provided on one side and the middle part of the hand-held concave arc 132.

[0075] During operation, the hand can be applied to the holding concave arc 132, and the finger can trigger the switch key installed in the operation key port 132-1. Specifically, the switch key can adopt a physical silicone button, which together with the LCD screen of the screen display component 60 forms a human-computer interaction method, which has the advantages of being simple and practical.

[0076] Reference Figure 16-17 and Figure 5 In a possible implementation, the heat dissipation assembly 30 includes a heat conducting plate 31, a bent heat pipe 32, a heat sink 33, a heat dissipation fan 34, and a heat dissipation hole group 35. The first surface of the heat conducting plate 31 is connected to the back of the LED light source assembly 20, and the area of ​​the first surface is not less than the surface area of ​​the back; one end of the bent heat pipe 32 is attached to the second surface of the heat conducting plate 31, and the other end thereof is bonded and connected to the bottom surface of the heat sink 33. The bent heat pipe 32 is used to arrange the LED light source assembly 20 and the heat sink 33 in a straight line;

[0077] The lower shell 13 is symmetrically provided with heat dissipation hole groups 35 on both sides corresponding to the heat dissipation assembly 30. Furthermore, the heat dissipation hole group 35 has a preset pattern, and the preset pattern is formed by a combination of a porous shape arrangement and a change in aperture. The heat dissipation fan 34 is installed on the inner wall of the lower shell cavity 131 and close to the heat dissipation hole group 35 on one side through a fan slot plate 341, and the heat sink 33 is arranged in the installation space between the heat dissipation fan 34 and the heat dissipation hole group 35 on the other side.

[0078] Furthermore, a fan pressure plate 342 can be detachably installed on the top of the fan slot plate 341. The fan pressure plate 342 is mainly used to assist in reinforcing the cooling fan 34 and reduce the noise caused by vibration. At the same time, when the area of ​​the fan pressure plate 342 extends to the top of the heat sink 33, it is also beneficial to guide the natural cooling wind to flow in a concentrated manner, so that the heat dissipation is more sufficient.

[0079] When in use, the heat generated by the LED light source assembly 20 is directly and efficiently absorbed by the heat conducting plate 31, and then transmitted to the heat sink 33 over a long distance through the bent heat pipe 32. The heat conduction efficiency is high, and the phototherapy head is simplified into a phototherapy end structure, which promotes a small pen-shaped product appearance and achieves the effect of controlling the light source temperature not exceeding 75°C. Furthermore, based on the unilaterally arranged heat dissipation fan 34, low-temperature air is introduced from the heat dissipation hole group 35 on one side, flows through the fin gap of the heat sink 33, fully takes away the heat of the fins and becomes high-temperature air, and then discharged from the heat dissipation hole group 35 on the opposite side. The preset pattern can not only improve the heat dissipation effect, but also take into account the aesthetics.

[0080] Reference Figure 5 and Figure 16-17 In a possible implementation, the built-in power supply assembly 40 includes a built-in battery 41, a battery cell 42 and a battery positioning compartment 43. The battery positioning compartment 43 is arranged at the bottom of the inner wall of the lower shell 13, and the inner walls of the lower shell cavity 131 on both sides of the battery positioning compartment 43 are also symmetrically provided with locking card plates 422; both ends of the battery cell 42 are provided with a clamping portion 421 detachably connected to the locking card plate 422, which is used to constrain the built-in battery 41 in the battery positioning compartment 43 from the top.

[0081] For example, please refer to Figure 5 , 16 and Fig.17 As shown, the battery positioning compartment 43 can be integrally formed on the inner bottom wall of the lower shell 13 to accommodate the built-in battery 41; the clamping portion 421 of the battery 42 can be a notch opened at its end, and the locking card plate 422 is used to lock the position of the battery 42 and maintain it on the upper part of the built-in battery 41 after being connected with the notch. Specifically, the locking card plate 422 can be a clamping strip integrally formed on the inner side wall of the lower shell 13, and the clamping strip can be connected with the notch. The built-in power supply assembly 40 in the embodiment of the present application is a structure in which the battery is not replaced, so it is convenient to optimize the design of the battery compartment area and the battery power supply connection, which is conducive to further miniaturization of the product.

[0082] More specifically, the built-in battery 41 can be a single 18650 lithium battery of 2200-2600mAh, which is expected to provide at least 1 hour of continuous illumination of the device. Further, a socket for connecting to an external power adapter plug can be provided at the closed end of the pen-shaped housing 10, for example, the socket can be a type-c interface.

[0083] In a possible implementation, the LED light source assembly 20 uses an LED light source board 21 with a six-bead array or a nine-bead array, which is configured to obtain the following technical parameters:

[0084] Peak wavelength 308±2nm; irradiation intensity 20-60 mW / cm²; effective irradiation area 2.5cm²±10%; the stability of ultraviolet irradiation intensity is no more than 5%, and its unevenness is 33% or 26.6%.

[0085] The LED light source board 21 of this embodiment, when combined with the above-mentioned light output end design, can achieve an effective irradiation area of ​​2.5cm²±10%, which meets the requirements of small-area precision treatment; at the same time, the LED light source board 21 of this embodiment, when combined with the above-mentioned heat dissipation component 30 design, can achieve a stability of ultraviolet radiation intensity of no more than 5%, which meets the technical standards.

[0086] When the LED light source assembly 20 adopts an LED light source board 21 with a six-lamp bead array, the light source driving part adopts a single-stage constant current boost method, with six lamp beads in three series and two in parallel; when the LED light source assembly 20 adopts an LED light source board 21 with a nine-lamp bead array, the nine lamp beads are in three series and three in parallel, and a single-stage constant current boost method is used.

[0087] In order to save costs, in this embodiment, the LED light source assembly 20 can all be made of 308nm ultraviolet LEDs made of PW chips, and driven by a boost constant current method. The design of the LED light source board 21 based on a six-bead array or a nine-bead array can achieve a minimum of 20mW / cm 2 , maximum 60mW / cm 2 Irradiation intensity, 20mW / cm 2 The low intensity is safer and more effective when used for children, 60mW / cm 2 The high intensity is a value that cannot be achieved by small-area treatment products on the market, which is conducive to achieving the expected treatment effect in a shorter irradiation time. In terms of light source uniformity, the maximum deviation of the simulated uniformity analysis of the prior art is 60%, and the uniformity is poor. However, the non-uniformity of the six-bead solution of this application is 33%, and the non-uniformity of the nine-bead solution is 26.6%, and the uniformity is significantly improved.
