Description

Skin Injury Treatment Band using Flexible OLED and Control Method Thereof}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band for skin wound treatment using a flexible OLED (organic light emitting diode; referred to as 'OLED') and a control method thereof. The present invention relates to a band for skin wound treatment using a flexible OID and a method of controlling the same.

The present applicant has proposed Korean Patent Application No. 2007-0080751 (name of the invention: an adhesive autodynamic therapy apparatus using OLED; hereinafter referred to as 'quotation invention'), which is opaque and flexible to cover the lesion area. The adhesive tape with the adhesive layer formed on the bottom of the synthetic resin tape, which is an insulator, and the thin film OLED having the same size as the lesion area at the center of the bottom of the adhesive tape, and the OLED connected to the OLED by being located on one side of the adhesive tape. An OLED characterized by having a drive control circuit for turning on the OLED for a set time after the set time for driving, and a battery which is located on one side of the adhesive tape and connected to the OLED and the drive control circuit to supply power A self-adhesive adhesive photodynamic therapy device has been proposed.

In this way, the cited invention can wait a long time until the photosensitizer is sufficiently reacted to the lesion and then automatically perform a series of photodynamic therapy procedures for irradiating a laser or visible light for a set time, thereby prolonging a bandage. Discomfort such as wound around the lesion area or the photosensitizer absorption waiting time, there is an effect that can be eliminated discomfort due to the restraint of the patient's body during the light irradiation period.

Accordingly, the invention of the cited invention greatly simplifies and facilitates the photodynamic treatment process, the inconvenience of the patient waiting for a long time in the hospital is eliminated, and the free activity is possible, but the light of the OLED is applied only to the lesion area of the patient. Intensive irradiation is to optimize the state of light at a wavelength or intensity suitable for the lesion, and to be irradiated for an optimal time, the effect of the ideal photodynamic therapy can be expected.

Therefore, a method of utilizing the cited invention to treat the damaged or inflamed wounds of the skin by utilizing the photodynamic treatment device according to the cited invention can be considered, but the OLED used in the cited invention has a thickness thereof. Is thin, but made of a rigid material, which has a lot of curvature, and it is difficult to be in close contact with the skin where deformation such as bending and unfolding occurs frequently.

In addition, since the strong OLED material may further damage the wound or inflammation of the skin and worsen the condition, it is difficult to realize the practical use.

The purpose of the present invention is to replace the light source emitting inside the wound treatment protective band with an OLED capable of surface emitting, in order to improve the cited invention, as well as a flexible OLED made of a flexible material, and in direct contact with the skin The present invention provides a band for treating skin wounds using a flexible OLED and a method of controlling the same, by allowing the light emitting surface to be realized on an optical fiber screen, thereby providing a soft fit to the skin in contact with the fiber.

In addition, the present invention is to provide a band for the treatment of skin wounds using a flexible O LED and a control method thereof by optimizing and setting the light emission retention time and the light emission form of the flexible OLED, to obtain a more effective cosmetic effect.

In order to achieve the above object, the present invention provides a substrate, an anode, and a cathode in an adhesive layer on the bottom of an opaque, flexible, and insulator synthetic resin tape, and an organic thin film and an OLED composed of a plurality of TFT pixels are disposed therebetween. A microcontroller, a built-in battery, and an operation means composed of a power button, a first button, a second button, and the like, connected to the aforementioned OLED,

The above-mentioned substrate has a glass plate flexible OLED structure having a thickness of 100 to 200 μm, and a polymer film for preventing cracks having a thickness of 3-5 μm is formed thereon, and a band for skin wound treatment using the flexible OLED, and a control method thereof. Suggest.

In this way, the present invention is thin in thickness, and at the same time to install an OLED that can emit light across the entire surface of the light emitting surface to treat the wound or inflammation of the wound, the side effects as in the case of drug use Increasing the production of capillaries, increasing the amount of oxygen in the blood, promoting the production of collagen and ATP (Adenosine Triphosphate), phagocytes Of course, the present invention has the effect of relieving inflammation and acquiring the effects of wound healing by activating pha-gocytosis. As it is deformed together, it provides a soft fit and does not physically irritate skin wounds or inflammations. There is a useful effect of obtaining this excellent therapeutic effect.

In addition, the present invention is to set up the light irradiation time, irradiated form, optimized treatment is possible to provide convenience of use as well as to obtain a safe and high skin treatment effect.

Referring to the present invention in more detail with reference to the accompanying drawings as follows. As is well known, when a forward voltage is applied to the OLED 10, holes are injected at the anode 11 at the highest Occupied Molecular Orbital (HOMO) level of the pixel 19, which is an organic layer, and at the cathode 12, LUMO (Lowest Unoccupied Molecular) Electrons are injected into the orbital. The injected electrons and electrons form an exciton, which emits light as it moves to the ground.

10A and 10B show typical structures of the OLED 10 used in the present invention.

As can be seen from the above, the present invention is opaque, flexible, and the substrate, the anode 11, and the cathode 12 are provided in an adhesive layer on the bottom of a synthetic resin tape, which is an insulator, and an organic thin film and a plurality of TFTs therebetween. By installing an OLED (10) of pixels (19)

The microcontroller 23 and the battery 24 are built in one side of the synthetic tape, and an operation means composed of a power button 26, first and second buttons 27 and 28, etc. is provided on the outer surface thereof. ), But by applying power to the microcontroller 23 which irradiates light having a wavelength of 600 μm to 1300 μm by the OLED 10 on the inner surface 22 of the band, and adjusts the irradiation time and brightness thereof. It can be adjusted according to the expert's prescription, and irradiated to the living body by being irradiated with the appropriate brightness for the most ideal time to penetrate the living tissue to excite the molecules of the cells. Accordingly, the production of capillaries, the increase in the amount of oxygen supported by the blood, as well as the activation of phagocytosis (pha-gocytosis) can be used to treat skin wounds and relieve inflammation.

Both kinds of general OLED 10 usable in this invention can be utilized. One is Passive MATRIX OLED and the other is ACTIVE-MATRIX OLED. The passive OLED has a simple structure, but the selected pixel emits light for a short time, so that the device is degraded and consumes a lot of power, which is disadvantageous in a wide application skin area. In addition, in the case of the active emission type OLED, since the emission area is reduced by the TFT in the pixel, the top emission type shown in FIG. 2 is suitable. In particular, the present invention should use a flexible OLED. Therefore, for this purpose, the OLED substrate 13 as shown in FIG. 3 can be made a transparent glass plate 14.

However, since the glass plate 14 is easily brittle, such as bending, the glass plate 14 is coated with a polymer film on a thin glass having a thickness of about 100 μm, thereby reinforcing brittleness so as not to be broken while being light.

The flexible glass plate 14 is thin and flexible but has excellent glass transition temperature, thermal expansion, hardness, compatibility of the multilayer coating thin film, thickness uniformity and flatness, and chemical resistance.

In addition, in the flexible OLED 10, an electrode protective layer 25, a cap 17, and a cover 18 are formed on the cathode 12.

In the present invention, the OLED substrate 13 may be a metal plate 16. In this embodiment, by using a steel material, the thin film is made of a flexible, heat-resistant and durable metal thin film, which is limited due to the opacity of the steel material.

In addition, in the case of the OLED substrate 13 made of steel, the planarization film should be coated and used because it is insufficient to satisfy the condition required by the OLED 10 in terms of flatness. On the other hand, in the case of the OLED substrate 13 made of steel, there is an advantage over the flexible glass plate 14 in terms of process temperature, thermal expansion, chemical resistance and durability.

In particular, in the case of the OLED substrate 13 made of steel, it is more advantageous than the case of the flexible glass plate 14 in that a TFT process performed at high temperature can be performed without difficulty in order to implement a flexible active drive type OLED.

In addition, in the present invention, the OLED substrate 13 has a glass plate structure, and as shown in FIG. 4, a light guide plate formed of an optical fiber screen 15 can be used. The optical fiber screen 15 used in the present invention is composed of a plurality of parallel arranged optical fibers, and is preferably arranged at right angles to the surface of the screen to transmit light through the fibers. Such an optical fiber screen can be used, for example, in mass production by Scott Corporation (Yonkers, New York).

The diameter of such optical fibers is preferably about the same as or smaller than the diameter of the light emitting elements of the display, so that at least one fiber is arranged at a density that allows light to pass from each pixel of the display. According to this embodiment, the light emitted from the OLED 10 to the skin surface through the fibers constituting the optical fiber screen 15 can be irradiated with the skin, it is possible to smooth the touch of the skin when wearing the band As the epidermis of the skin is blocked by the substrate, it becomes difficult to breathe the skin, thereby minimizing the discomfort and discomfort and irritation of skin physiology due to the generation of oil and moisture.

In the present invention, the OLED substrate 13 has a metal plate 16 structure as shown in FIG. 5, wherein the upper cap 17 is made of a transparent material and the optical island surface 15 is formed on the light guide plate thereon. By forming a, it is possible to be a top emission type.

In addition, in the present invention, as shown in Figure 6, in the structure of the OLED substrate 13 in the glass plate 14 structure, the cap 17 is made of a transparent material, the light guide plate on the tapered optical fiber of the upper and lower side in the drawing By forming the screen 15, it is possible to widen the light diffusion range and increase the skin irradiated surface. In addition, as shown in FIG. 7, if necessary, the tapered optical fiber screen 15 of upper and lower beams is formed on the drawing to narrow the light diffusion range so that the light can be focused to increase the partial focusing luminance. do.

In addition, in the present invention, even when the OLED substrate 13 is made of the metal plate 16 and the cap 17 is made of a transparent material, the tapered optical fiber screen 15 of the upper and lower sides of the drawing is formed on the light guide plate thereon, It is possible to increase the skin irradiation surface by widening the light diffusion range. In addition, if necessary, by forming a tapered optical fiber screen 15 of upper and lower light, the light diffusion range can be narrowed so that the light can be focused to increase the brightness and reduce the skin irradiated surface.

In addition, in the present invention, it is preferable that the thickness of the flexible glass plate 14 described above is 100 μm or more and 200 μm or less, and a polymer film for preventing cracks is preferably coated with a thickness of 3 to 5 μm thereon.

In addition, in the case of the present invention, the flexible OLED substrate 13 is a synthetic resin film, PET (Polyethylene terephtalate), PES (Polyether-sulphone), PC (Polyester-carbonate), PI (Polyimide), PEN (Polyethyenenapthalate) It is desirable to.

That is, the flexible OLED substrate 13 used in the present invention is thin, light, flexible, and can be rolled to roll process, but the productivity is high, but the moisture and oxygen permeability is 1 × 10- Since it is 10 ~ 1000g / m2 / day, which is less than 5g / m2 / day, inorganic membranes such as SiOX, SiNX, AlO, and MgO should be coated to minimize moisture and oxygen permeability. Accordingly, in the present invention, the organic film prevents pinholes formed during the deposition of the inorganic film and buffers the stress to prevent peeling and cracking of the inorganic film, thereby ensuring low moisture permeability and low oxygen permeability.

In addition, in the present invention, indium tin oxide (ITO) used as the anode 11 is made of zinc oxide (GZO), which is a transparent conductive material, or doped with ZnO to prevent cracking and peeling due to strain. By using the ZIO, the characteristics such as flexibility, flatness, sheet resistance, transmittance, and work function can be satisfied.

As described above, the present invention is controlled by the microcontroller 23 so that the light of the intensity set for the time set by the expert is irradiated to the skin, and when the battery 24 is exhausted during such repeated use, It can be used repeatedly by replacing it.

In addition, in the present invention, the TFT, which is a switching element of the flexible OLED 10 controlled by the microcontroller 24, may be made to emit light across the entire surface by passing a current at a time. However, as shown in FIG. As shown in FIG. 9, intermittent lighting may be performed at regular time intervals. In addition, it can be made to emit light in various forms as needed, and also change the wavelength of the light, this series of various operation control is stored in the memory of the microcontroller 23, stored in several operating mode programs and connected to By operating the buttons 26, 27 and 28, it can be set to operate in the optimum mode.

Set the operating time to 15 minutes, press three times to set the operating time to 20 minutes, press four times to set it to 25 minutes, and press five times to set it to 30 minutes.

In addition, when the user presses the second button 28 once, the first operation mode in which the microcontroller 23 continuously supplies the power of the battery 24 to all the TFTs of the flexible OLED 10 for a set operating time is provided. When the second button 28 is pressed twice, the power of the battery 24 becomes a second operation mode in which the power of the battery 24 is sequentially supplied to the TFT of the flexible OLED 10 in the column or the row. When the second button 28 is pressed three times, power is supplied to all the TFTs of the flexible OLED 10 for 3 seconds, the power supply is cut off for 2 seconds, and the power is again supplied to all the TFTs of the OLED 10 for 3 seconds. It is set to the third operation mode to repeat the process.

After setting the operation time and operation mode as described above, by pressing the power button 26 and the first button 27 at the same time, the microcontroller 23 recognizes this as a setting completion and operation start command. The flexible OLED 10 of the inner surface 22 is started to operate in the set operating time, operating mode.

At this time, the user needs to organize the foreign matter on the wound and to prepare the skin damage in order to enhance the skin treatment effect.

In addition, the band according to the present invention should be used to peel off the release paper 29 before sticking to the skin. After the present invention is adhered to the wound or inflamed site of the skin, the microcontroller 23 automatically cuts off the power after the light emitting operation of the flexible OLED 10 is performed in a set operation mode for a set time. In order to indicate the completion of the operation, the light emitting diodes 30 installed on the outer surface of the band is required to be considerate so that the user can recognize the completion of the operation.

In this way, after the operation is completed, the band according to the present invention can be recovered, and the foreign substances on the inner surface can be wiped off and reused.
