Description

Multifunctional phototherapy veil

Technical Field

The invention relates to a multifunctional phototherapy veil. And more particularly, to a multifunctional phototherapy veil using an OLED light emitting panel as a light source.

Background

Technologies such as Low Light Laser Treatment (Low Light Laser Treatment) and photobiological modulation (PBM) appear in the middle and later stages of the 20 th century, and both of them are applied to the medical field by using illumination as a means for treating diseases (Michael r. There are many studies that red to near infrared illumination has been found to help promote the regeneration of tissues such as collagen and skin cells, and can be applied in the fields of anti-wrinkle cosmetology, wound healing promotion, spot removal, etc. (Chan Hee Nam et al, dermotologic Surgery,2017, 371-380, daniel barolet, semin Cutan Med surg,2008,27 227-238, yonggin jeon, adv. Meanwhile, blue light irradiation is also the most effective means for treating pediatric jaundice at present, and phototherapy products using semiconductor Light Emitting Diodes (LEDs) as light sources and integrated on flexible substrates are gradually emerging (US 6811563B2, US6596016B, US6974224B 2), and even commercial phototherapy blankets for treating neonatal jaundice, such as BiliTX products of Philips corporation (https:// www. Philips. Com. Cn/healthcare/product/HC 866437/biltix-).

Various phototherapy devices aimed at anti-aging skin have been applied in beauty parlors, for example, LED masks have been commercialized on the market. These products arrange the LED chips in an array on the back of a plastic face mask. LEDs are high intensity point sources of light, often accompanied by heat generation. LED light sources typically incorporate heat sinks to reduce temperature, and the LEDs must be spaced apart for heat dissipation when used in an array format. This results in three disadvantages of the LED mask. First, such masks are thick and heavy because heat dissipation considerations necessitate the addition of a heat sink and must be located some distance from the person's face for safety. Some of these masks weigh up to 1.6 kilograms and are less comfortable to wear on the face. Secondly, in the array arrangement, the LEDs are all independent at a certain position, and have a distance from each other, which results in uneven light emission. In cosmetic treatments, such uneven lighting may lead to uneven skin tone or require multiple treatments in different areas. Finally, to cover the entire face, a large number of LEDs, sometimes as many as 200 chips, need to be used, which increases the difficulty of LED screening, assembly and maintenance.

In contrast, OLED is a surface light source, a cold light source, is not glaring, and has a light and thin property, making it very easy to integrate into a flexible substrate. This makes OLEDs ideal light source options for wearable applications, and the related patent applications also cover various fields in recent years. Patent applications CN205108772U, CN204951964U and US2012155057A1 all mention that OLED light sources can be used as wearing products for medical treatment. US20100179469A1 mentions the use of OLEDs with wavelengths around 450nm as light sources for the treatment of pediatric jaundice; the inventor's previous application CN111450421A proposed that the flexible green OLED is converted into blue light to treat jaundice in combination with the conversion on TTA; application CN203694423U and prior application CN109173071A by the present inventors mentioned the use of OLEDs to prepare phototherapy masks; the inventor's prior patent applications CN111481833A, CN111514466A, CN111544774A and CN112754764A mention the use of OLED for the preparation of hair growing cap, slimming shaping clothes, phototherapy socks and band-aid, respectively.

Besides the above-mentioned phototherapy application, lifting the mandible and lightening the neck line are also important items for medical cosmetology. The product currently on the market for lifting the lower jaw is a lifting belt, as shown in fig. 4a (https:// detail. Tmall. Hk/hk/item. Htmspm = a1z10.3-b-s.w4011-22176177950.20.6c2a69ce0qyrj0&id =604917088657& = d4772db3f94d35694a538c5f7acd & -abbucket = 11), mainly treated from a physical aspect using cloth with special elastic lifting in combination with unique weaving technology. The effect of the lifting belt is very limited, because the physical treatment treats the symptoms and does not treat the root causes, the lifting belt is easy to repeat; moreover, the lifting belt is designed to be special in appearance, can be used at home only and cannot be used at any time and any place. A neck print care instrument, as shown in FIG. 4b (https:// detail. Tm. Total. Com/item. Htmspm = a1z10.3-b-s.w4011-18825636492.53.7d465781ckocjs &id = 5918194848 = 2e4f3f02a2e9987b8a2b259e268e62 &abbucket = 11), 459 LED beads are integrated in a housing, and neck wrinkles are phototherapy by emitting red and near infrared light. This device weighs more than 240 grams, is bulky, and suffers from the drawbacks of the LED phototherapy products described above. Neck print phototherapy, as shown in fig. 4c (https:// detail. Tm. Call. Hk/hk/item. Htmspm = a1z10.1-b-s.w5003-231578789.3.

However, the appearance of the neck beautifying instrument is still not beautiful enough, the neck beautifying instrument can only be worn at home, and a hand-held controller is needed, so that the neck beautifying instrument is inconvenient to use.

Fig. 2 shows a dual-cell stacked device, and a third light-emitting cell and a second charge generation layer can be added to form a three-cell stacked device. The fabrication of both single and stacked OLED devices is well known in the art and not described in detail herein.

A schematic cross-sectional view of an OLED light-emitting panel is shown in fig. 3a-3 d. The OLED light emitting panel 300 includes a substrate 301, an OLED device 302, a pair of contact electrodes 304 electrically connected to the OLED device 302, and an encapsulation layer 303 (but exposing the contact electrodes 304). The substrate 301 may be a rigid glass, preferably flexible, such as ultra-thin flexible glass, more preferably a non-brittle material, including but not limited to plastic (PET, PEN, PI), textile, leather, paper, metal foil, or a combination thereof. In particular, the substrate 301 may be a material (e.g., PI, polyimide-based material) that is coated on the supporting substrate in the form of a solution in advance, cured and planarized for device fabrication. After the device is prepared, it is peeled off from the supporting substrate using a laser and transferred to other flexible films as needed. The substrate 301 may be additionally coated with a moisture barrier layer (not shown). OLED device 302 can be a bottom emitting device or a top emitting device, with a top emitting device being preferred because of its higher luminous efficiency. OLED device 302 can be a single layer structure or a stacked layer structure, with a stacked layer structure being preferred because it has a longer lifetime at the same brightness and because a thicker film layer is beneficial for increasing production yield. The organic material in the OLED device 302 may be formed by evaporation in a vacuum chamber by thermal evaporation (vacuum evaporation), or may be formed partially or even entirely by a solution process, including but not limited to ink jet printing (ink jet printing), spin coating, organic vapor spray printing (OVJP), and the like. The encapsulation layer 303 may be glass adhered to the device by UV curable adhesive, preferably a flexible encapsulation layer, also called thin film encapsulation layer, generally having a thickness of 5 μm or more, such as a single inorganic thin film, or a multilayer structure of organic and inorganic thin films alternating, and is formed by PECVD, ALD, printing, spin coating, etc. The contact electrode 304 may comprise at least one anode contact and one cathode contact. A front cover film 305 may be added to the OLED light-emitting panel described above as shown in fig. 3 b. The front cover film 305 may be a Flexible Printed Circuit (FPC) board on which a pre-designed circuit is printed and electrically connected to the OLED device 310 through the adhesive structure 304. In another alternative, the adhesive structure 304 may be an FPC frame and the front cover film 305 may be a sheet of plastic film to provide mechanical support. A specific description of the use of an FPC board to drive an OLED light-emitting panel can be found in chinese patent application US20190376650A1, which is incorporated by reference in its entirety and which is not within the scope of the detailed description of the present application. The front cover film 305 may also include a light extraction layer. When OLED device 310 is top-emitting, front cover film 305 is transparent in the light-emitting area. The front cover film 305 may be a combination of the above. Additional thin film encapsulation layers 306 may be applied to one or both sides of the substrate 301 as shown in fig. 3 c. The front cover film may also be coated with an additional thin film encapsulation layer 306, but is not shown in this figure. In fig. 3d, a back cover film 307 is overlaid onto the substrate 301. The back cover film 307 may be used for mechanical support. When the OLED is a bottom-emitting device, the back cover film 307 may be a light extraction layer and transparent. The back cover film 307 may be a combination of the above. Such an OLED light-emitting panel is an OLED light source when electrically driven to form an electrical connection with an external device (regardless of whether it is in an on or off state), and is one of the essential components of the present invention. The OLED devices in the above-mentioned OLED light-emitting panels all use common organic layers, in particular having common organic light-emitting layers, i.e. non-pixellated processes, which can only emit light of one color at a fixed operating point. The OLED light-emitting panel can emit at least one light with the peak wavelength of 400-2000nm, preferably, the OLED light-emitting panel can emit at least one light with the peak wavelength of 450-1000nm, and more preferably, the OLED light-emitting panel can emit at least one light with the peak wavelength of 600-970 nm.

The phototherapy veil of the invention can be integrated with OLED light-emitting panels, and the light-emitting panels in different areas can emit light with different colors to meet different requirements. There are several ways to achieve light with a variety of different wavelength bands: the first is to design a pixelized layout on the same OLED light-emitting panel and then independently drive each pixel, or to group pixels and then independently drive different groups. Preferably, a flexible OLED light-emitting panel is used, i.e. encapsulated with a flexible substrate and a thin film. The pixels here usually have a light-emitting area in the order of millimetres, i.e. a minimum dimension greater than 1mm ² Preferably greater than 5mm ² . For example, a flexible OLED light-emitting panel 500 shown in fig. 5a may include a flexible OLED substrate 501 on which a series of OLED devices 502 are manufactured by patterning, and these devices share the same thin film encapsulation layer 503, in this case, each light-emitting unit is an OLED device, and the whole flexible OLED light-emitting panel is a light source. In this case, the metal wires may be arranged on the panel at the same time of preparing the anode or the cathode for electrically connecting the OLED devices 502, and the method of the metal wires is well known in the art and will not be described herein. Different OLED devices are controlled by the circuit control system, so that different devices can emit light with different colors, or the same device works under different currents, and multiple colors are realized. A variation of this is a flexible OLED light emitting panel 510 as shown in fig. 5b comprising a flexible OLED substrate 501, a series of OLED devices 502, but each device enjoys a separate encapsulating layer 513, and preferably a thin film encapsulating layer. At this time, the different OLED devices 502 can be connected through metal wiring, and can also be electrically connected through an FPC circuit board, thereby greatly improving the possibility of conductivity and circuit complexity. All in oneAlso, a single or multiple OLED devices 502 can be independently driven through these electrical connections. Under the two conditions, if light with different colors is emitted, different device structures can be evaporated on different OLED devices by using a metal mask, and particularly, the material of a light emitting layer is changed; it is also possible to refer to the arrangements described in patent applications CN111081892A and CN111081891A, all of which use the same structure of independent units, multiple light emitting layers, with the change of colour being achieved by the movement of the recombination zones at different working points. Alternatively, individual OLED light emitting panels may be arranged in an array, as shown in fig. 5c, where each light emitting panel comprises an individual substrate 521, an OLED device 502 and an individual encapsulating layer 513. The advantage of this arrangement is that a non-flexible OLED light-emitting panel and/or a non-flexible encapsulation layer can be selected, and the light source formed into an array can still have a certain flexibility as long as the area is small enough. The individual OLED light emitting panels may be cut from the same motherboard, for example, using the same individual unit multi-light emitting layer structure, or may be reassembled by selecting different structures of devices from different motherboards. The scheme has the advantages that the device can be screened, the yield is improved, and the color diversity of products is also improved. The independent light-emitting panel shown in fig. 5c may be arranged and combined through an FPC or front and rear cover films, etc. as required, to form a dot matrix physically connected to each other, and reference may be made to the method disclosed in CN208750423U, which is not the focus of the research in this application and is not described again. Also, the panels may be independently controlled, giving different operating currents. The array arrangement can realize multicolor luminescence and zone control, for example, different treatment effects can be achieved by using different wavelengths of light for the lower jaw and the neck region, or different light intensities and durations can be performed for different regions. The local illumination can further reduce the power consumption and save energy.

Fig. 6a shows a schematic of the external structure of a phototherapy veil 600, "external" referring to the side of the veil away from the face of a person. Phototherapy veil 600 includes a shell 601 and fastening device 602. In fig. 6a, the fixing device 602 is embodied in the form of an ear hook, but the fixing device 602 may be in other forms, including but not limited to a strap, an elastic band, a button, a zipper, a hook and loop fastener, etc., and the fixing device 602 is used to fix the whole phototherapy veil on the face without falling down. The housing 601 is further divided into a nose and mouth area 6011, a chin area 6012, and a neck area 6013. Note that the chin area 6012 is only partially visible in fig. 6a, and cannot be fully shown in fig. 6a because the shell in this area will fold over to wrap around the chin. The shell may be made of materials including, but not limited to, plastics, silica gel, rayon, natural textiles, and the like, and preferably, the natural textiles include, but are not limited to, silk, cotton, hemp, yarn, brocade, satin, and the like. Fig. 6b shows a schematic view of the interior of a phototherapy veil 610, with "interior" referring to the face of the veil that faces the person's face. From the internal schematic view, the veil comprises a shell 611 on which are integrated OLED light emitting panels 6111, 6112 and 6113 (panel 6113 on the other side of the figure) which mainly cover the chin area of the face and emit light with peak wavelength of 400-2000nm, preferably 600-1000nm, red and near infrared light towards the face, serving to lift and tighten the chin. The OLED light emitting panels 6111, 6112, and 6113 are preferably flexible panels. The housing 611 also contains a neck region, and an OLED light emitting panel 6114 is integrated in the neck region. The OLED light emitting panel 6114 can emit light of 600-1000nm toward the human body as well as emit light of a different color than the OLED light emitting panels 6111, 6112 and 6113. The OLED luminescent panel 6114 of the neck portion can function to remove wrinkles. Phototherapy veil 610 can also contain fixing device, and can be divided into two parts, and fixing device 6121 is the bandage form, is responsible for the veil of fixed oronasal part and lower jaw portion, and fixing device 6122 is the magic subsides form, is responsible for fixed neck veil. Phototherapy veil 610 may also include portions that cover the oronasal region 6110, but region 6110 may not be integrated with an OLED lighting panel. Moreover, the nose and mouth area 6110 may be made of a different material from the lower jaw area and/or the neck area, for example, the nose and mouth area 6110 may be made of a non-woven fabric similar to a medical mask, and the lower jaw area may be made of a flexible fabric. The method of integrating an OLED light-emitting panel into an elastic fabric can refer to the inventor's prior application CN111514466A. Thus, the mask portion of the oronasal region may function as a protective mask, while the mask of the mandibular portion may also function as a physical lift. The mask may further comprise attachment means in different regions, for example between the mandible and the neck, and between the oronasal and the mandible, and these attachment means may be removable and may be selectively used. Wherein, the connecting device includes but not limited to button, zipper, magic tape, etc. Note that although different regions of the face yarn may be selected from different materials, it is possible to define that these different regions, together with the connecting means, are associated with a housing 611. The phototherapy veil 610 also includes a driving device, which is not shown here. The driving devices provide external power and circuit control to the OLED panels 6111-6114, including but not limited to batteries, circuit boards, leads, wireless charging devices, bluetooth communication devices, etc. The driving device can also realize wireless Bluetooth connection with external electronic equipment and be controlled by the external electronic equipment, such as a switch, dimming control, partition control and the like. The external electronic device can be a smart phone, a smart watch, a tablet computer, a notebook computer, a computer and the like. Furthermore, the control can be combined with an application program (APP). The drive means may be integrated in any suitable part of the housing, for example in the region of the fixing means. Fig. 6c shows a schematic view of the interior of a phototherapy veil 620 (i.e., the side facing the face of a person). Phototherapy veil 620 includes a housing 621 having OLED light emitting panels 6211 and 6212 integrated thereon, covering the face (including the mandible) and neck regions, respectively, i.e. unlike phototherapy veil 610 in fig. 6b, phototherapy veil 620 can be used for phototherapy of both cheek regions simultaneously. Phototherapy veil 620 also includes two fixation devices 6221 and 6222 for fixing the veil on the face (including the chin area) and neck, respectively. The phototherapy veil 620 also contains a driving device, which is not shown here.

Fig. 7a shows an external schematic view (i.e., the side away from the face) of another phototherapy veil 700 including a housing 701 and a fastening device 702. The housing 701 further includes an oronasal region 7011, a mandibular region 7012, a neck region 7013, and a forethorax region 7014. The chest region 7014 may be connected to the neck region 7013 by a connection means (not shown). Fig. 7b shows a schematic view of the interior of a phototherapy veil 710 (i.e., the side facing the face of a person). Phototherapy face yarn 710 includes a casing 711 and two fixing device 7121 and 7122, and fixing device 7121 is the shape of bandage, is responsible for the face yarn part of fixed oronasal region and jaw area, and fixing device 7122 is the shape of magic subsides, is responsible for the face yarn part of fixed neck and front chest. OLED light emitting panels 7111, 7112, 7113 (panel 7113 on the other side of the figure) are integrated on the housing 711, and can cover the mandible area of a human face and perform phototherapy; the housing 711 also integrates an OLED light-emitting panel 7114 which can cover the neck and perform treatment; finally, the housing 711 also incorporates an OLED light panel 7115 that covers the chest portion and provides a firming treatment to the skin of the chest. Such a phototherapy veil 710, which of course also contains a drive, is not shown here. Of course in other embodiments, the phototherapy veil 720 as shown in fig. 7c may also integrate the OLED lighting panel 7110 in the oronasal region (including the cheeks). The mandibular area and the neck, and the neck and the forethorax areas may be provided with attachment devices that also form part of the housing 711.

In another embodiment, the housing of the phototherapy mask is foldable in the oronasal and mandibular areas, and the phototherapy mask is pulled open and covers the oronasal area only when needed, as shown in fig. 8. Phototherapy mask 800 may include a lower jaw area 801 having an OLED light emitting panel (not shown) integrated thereon, and lower jaw area 801 may be made of an elastic material. Chin area 801 may also include creases 8011 that when pulled apart cause phototherapy mask 800 to appear as a dotted line, including a region 802 that covers the nose and mouth. The OLED lighting panel integrated on the mandible region 801 may take many forms, for example it may be a single piece of flexible itself, or it may be multiple flexible or rigid panels integrated on a flexible housing similar to that described above; a plurality of OLED light emitting panels can also have blank areas, and can be folded to form a shape like a fold 8011; the original light-emitting area can not be shielded after the LED lamp is folded. The foldable phototherapy veil has the advantages that if only the phototherapy aiming at the lower jaw is needed, the foldable phototherapy veil can be used in a folded form, and the light-emitting area is concentrated at the lower jaw when the phototherapy is used; when needed, the phototherapy veil 800 can be further spread to form a large-area spread as shown by the dotted lines in fig. 8, and then the phototherapy veil 800 can further cover the mouth, nose and cheek areas 802, and can perform phototherapy on the mouth, nose and cheek areas. The phototherapy mask 800 further comprises an OLED light emitting panel 803 covering the neck portion and a connecting means 804 connecting the neck portion and the mandible area. Such a phototherapy veil 800, which of course also contains a drive, is not shown here. The dual-purpose veil can be used as a phototherapy product and can also be used as a mask, thereby achieving two purposes.

In other cases, the phototherapy veil may also include a second shell that may cover the outside of the first shell, i.e., the side away from the person. The second shell can be made of natural textiles, including but not limited to silk, cotton, hemp, yarn, brocade, satin and the like, and can be provided with a certain decorative pattern. The second shell can cover the first shell, and the appearance is more attractive. As shown in the schematic structural diagram of the phototherapy veil 900 in fig. 9, it includes not only a first shell 901 but also a second shell 902, and the second shell covers the first shell. The first housing may further be integrated with an OLED lighting panel 9011 covering both cheek regions, an OLED lighting panel 9012 covering the mandible region and a lighting panel 9013 covering the neck region. The phototherapy veil 900 of course also contains drive means, which are not shown here. Such phototherapy veil is particularly suitable for external occasion and dresses, can also play sun-proof effect.
