Description

Human-worn medical device using organic light-emitting diodes

[0001] The present invention relates to a human-attachable low-power light medical device for promoting wound healing using a flexible organic light-emitting diode.

[0002] The phototherapy market has seen a long history of research publications and product launches since its effectiveness was proven in the mid-1900s. Numerous devices for therapeutic or cosmetic purposes have been released, all sharing common characteristics. Currently, all phototherapy devices on the market utilize either laser or light-emitting diode (LED) sources. Consequently, they are often heavy and bulky, and because treatment requires a hospital visit, they are inefficient in terms of both space and time. Furthermore, since LED sources are point light sources, it is difficult to irradiate the desired area uniformly. Additionally, because irradiation is performed from a significant distance from the skin, it is not easy to apply the desired intensity to the wound. In particular, because these devices contain blue light harmful to the human eye, patients must cover their eyes during treatment; however, even with the eyes covered, there is a risk of exposure to light.

[0003] Therefore, there is a demand for small light medical devices that can be attached only to the necessary areas.

[0004] Accordingly, the present invention has been devised to solve the aforementioned problems, and the objective of the present invention is to provide a low-power light medical device (or wound healing aid) configured to be small enough to be attached only to necessary wound sites on the human body, and configured to easily attach to small wound sites anywhere on the human body by applying a flexible organic light-emitting diode panel and a battery to promote wound healing.

[0005] First, to summarize the features of the present invention, a medical device according to one aspect of the present invention for achieving the above objective comprises: a flexible front cover made of silicone material; a flexible back cover made of silicone material; and a control device mounted within a combination of the front cover and the back cover, comprising a flexible battery, a flexible printed circuit board operated by the flexible battery, and a red light-emitting OLED panel connected to the flexible printed circuit board and operated according to the control of a circuit of the flexible printed circuit board, wherein the red light-emitting OLED panel is configured to be attached to the back cover to irradiate red light or configured to irradiate red light through a window of the back cover, and wherein, according to the control of a circuit of the flexible printed circuit board, the red light-emitting OLED panel emits red light with an intensity of 600 to 700 nm wavelength at a low output (e.g., 2 mW / cm²). 2 From ) to high output (e.g., 25mW / cm² 2 By controlling the current flowing through the red light-emitting OLED panel to output up to ), the back cover is brought into contact with the human body, and the red light from the red light-emitting OLED panel assists in cell regeneration and activation for the healing of wounds on the human body.

[0006] The above red light-emitting OLED panel may be a flexible panel implemented on a flexible substrate.

[0007] The medical device may further include a separately configured double-sided tape for human attachment, and on the outer side of the back cover, include guideline markings that guide the position for attaching the double-sided tape for human attachment to the left and right of the red light-emitting OLED panel, and may provide a medical device for attaching one side of the double-sided tape to the guideline markings and attaching the other side of the double-sided tape to the human body.

[0008] On the outer side of the above-mentioned rear cover, a human body attachment tape is provided on the left and right sides of the red light-emitting OLED panel, and the release liner of the human body attachment tape may be peeled off and attached to the human body.

[0009] The above-mentioned front cover may include an embossing structure in which the outer surface appears as an uneven shape.

[0010] The above medical device further includes a transparent dressing film that is adhesive to the human body to prevent infection by blocking contact with external contaminants configured separately, and can irradiate the red light from the red light-emitting OLED panel onto the wound of the human body by attaching the transparent dressing film to the wound and contacting the back cover thereon.

[0011] The size of the medical device may be manufactured to be small, within 20 cm in width and 20 cm in height, and the size of the red light-emitting OLED panel may be manufactured to be small, within 10 cm in width and 10 cm in height. That is, the size of the medical device and the size of the red light-emitting OLED panel may be manufactured to be appropriately suitable sizes according to the type and size of the wound.

[0012] The above red light-emitting OLED panel may include a plurality of cells for applying 2-4V from the flexible battery in parallel to all cells.

[0013] The medical device may further include a charging terminal for charging the flexible battery.

[0014] The voltage magnitude of the flexible battery is fixed, and the resistance value of the variable resistor is varied according to the control of the circuit of the flexible printed circuit board to control the current flowing to the red light-emitting OLED panel, thereby controlling the light intensity to 2 mW / cm² 2 Up to 25 mW / cm 2The circuit of the flexible printed circuit board can be configured to allow setting the time during which the resistance value is maintained and varying, and setting the period of on / off of light generation during the time during which the resistance value is maintained and varying.

[0015] According to the human body-attachable medical device using an organic light-emitting diode according to the present invention, it can be manufactured in a compact size so as to be attached only to the necessary wound site on the human body, and by applying a flexible organic light-emitting diode panel and a battery, it can be easily attached to a small wound site anywhere on the human body, thereby promoting wound healing with a low output of the organic light-emitting diode panel.

[0016] Furthermore, according to the human body-attachable medical device using an organic light-emitting diode according to the present invention, by applying a harmless red light, particularly a wavelength of 600 to 700 nm (preferably 645 nm), to a wound to promote metabolic activity and induce cell proliferation, the wound can heal rapidly in the early stages through cell regeneration and activation, thereby reducing the possibility of scar formation. Since the present invention is manufactured in a human body-attachable form different from existing wound healing devices, there is no need to visit a hospital, resulting in excellent usability and convenience, and healing effects can be achieved with only a short period of irradiation. The intensity of the light source and the treatment time can be freely adjusted, and through the adjustment of intensity and time, it is a human body-attachable medical device that can be used not only for wound healing but also for various diseases such as pain relief. In addition, it is the first to utilize an organic light-emitting diode light source, enabling uniform irradiation and allowing for manufacturing with a flexible platform. Above all, because it is highly safe from the harmful effects of blue light, it is possible to provide a medical device that ensures photobiological safety.

[0017] Furthermore, according to the human-attachable medical device utilizing an organic light-emitting diode according to the present invention, it was verified in the preclinical stage that wound healing occurs rapidly, and it was confirmed that wounds heal quickly under conditions of a rapid irradiation time (20 minutes). The present invention is a medical device utilizing an organic light-emitting diode light source that can be freely attached to a wounded area to promote rapid wound healing through uniform light irradiation, and allows for continuous use through a rechargeable method. Additionally, by being manufactured in a human-attachable form, it provides a new medical device free from the constraints of time and space. Moreover, to overcome the limitations of existing phototherapy, an OLED surface light source capable of being manufactured in various form factors to enable uniform irradiation was developed and utilized, rather than a laser or general LED light source. It was also developed in a flexible form to allow users to freely attach and receive treatment without visiting a hospital. Furthermore, to enable continuous use rather than being a disposable product, it is designed to operate with a built-in battery charged via a charging terminal.

[0042] The above front cover (110) is formed with an embossing structure (115) on the outer surface that appears as an uneven shape, so that it can be flexibly bent and easily attached to any part of the human body, and its durability can also be improved.

[0043] Additionally, the back cover (120) is a part that the red light-emitting OLED panel (133) adheres to the wound area of ​​the human body.

[0049] FIG. 5a shows the size and 5 positions of the red light-emitting OLED panel (133) of the present invention, and FIG. 5b is a graph to explain the uniformity of optical characteristics at the 5 positions.

[0050] Referring to FIG. 5a, the planar light source cells (133-11) constituting the OLED panel (133) are composed of 20 cells (133-11) on a substrate measuring 15 mm in width and 13.4 mm in height. The planar light source cells (133-11) are connected in parallel with 2-4 V from a flexible battery (131) to produce a red light intensity of 600 to 700 nm wavelength (645 nm in the example of FIG. 4b) at a low output (e.g., 2 mW / cm²). 2 From ) to high output (e.g., 25mW / cm² 2 Output voltage can be up to ). Here, it is preferable for the output voltage of the flexible battery (131) to be 2-4V for small size, but this is exemplary and other output voltages such as 5V, 7V, 12V may be used depending on the case. The horizontal and vertical dimensions of the cells (133-11) for the surface light source constituting the OLED panel (133) are not important, but it is preferable to arrange them in parallel as densely as possible so that they emit light in the form of a surface light source.

[0051] The light source of the OLED panel (133) of the present invention was measured at 5 points (1 to 5) to verify the uniformity of the wavelength as shown in FIG. 5a, and as shown in FIG. 5b, the results of measuring the radiance and peak wavelength at each of the 5 points (1 to 5) confirmed that the overall uniform wavelength was approximately 10%.

[0052] In the present invention, the OLED panel (133) may be implemented on a non-flexible substrate such as glass when it is small in size, such as within 2 cm in width and within 2 cm in height. However, when it is manufactured in a larger size, or even if it is smaller, a flexible substrate such as polyimide (PI) may be used as a substrate that can be bent as needed.

[0053] Each cell (133-11) of the OLED panel (133) may have an organic light-emitting layer (Emissive Layer), an electrode layer (Anode and Cathode), and an encapsulation layer on the substrate as described above.

[0054] The above organic light-emitting layer is a layer in which an organic material reacts to an electric current to generate light. This layer is composed of a thinly coated organic material, and the color may vary depending on the composition of the organic material used. In the present invention, it is configured to emit a red wavelength (600 to 700 nm). The above electrode layer transmits current by having a transparent electrode and a reflective electrode located above and below the light-emitting layer, respectively. In flexible OLEDs, the electrodes may also be made of a material that is transparent and bendable (e.g., graphene, silver nanowires, etc.) to simultaneously ensure conductivity and flexibility. The above encapsulation layer is a layer for protecting the above organic light-emitting layer from external moisture or oxygen. It may be covered with glass, but in flexible panels, Thin-Film Encapsulation (TFE) technology may be used. The above thin-film encapsulation is composed of a thin multilayer structure to maintain lightness and flexibility. Additionally, if necessary, each cell (133-11) of the OLED panel (133) may be configured in a tandem structure.

[0056] As shown in FIG. 6, the wound healing medical device (100) of the present invention is manufactured in a stable rectangular shape with rounded corners on both the front cover (110) and the back cover (120). The front cover (110) and the back cover (120) are preferably made of silicone material so that they can be flexibly attached to the wound area, and an on / off switch (132-1) and a charging terminal (132-2), such as a C-type charging terminal, can be arranged to be exposed to the outside. As described above, the back cover (120) can be configured so that the user can attach it to the human body around the wound area using double-sided tape guideline markings (121) or fixed tape (122) on the left and right sides of the OLED panel (133).

[0057] FIGS. 7a and 7b are drawings illustrating the experimental process for observing wound healing effects in the preclinical stage using the present invention and the wound healing stage after light irradiation.

[0058] Referring to Fig. 7a, first, a nude mouse is placed under respiratory anesthesia and secured to a bed (1).

[0059] Next, draw a shape for making a wound about 8 mm x 8 mm in size on the back of the nude mouse (2).

[0060] Next, the dermis layer of the shaped mouse's back is removed using surgical scissors to create a wound (3).

[0061] Next, a transparent dressing film (190) is placed over the wound to remove exudate and block contact with external contaminants to prevent infection (4).

[0062] Next, the OLED panel (133) of the back cover (120) of the medical device (100) of the invention is placed on a transparent dressing film (190) (e.g., 3M tegaderm), and the medical device (100) is attached and fixed to the back of the mouse using double-sided tape or the like from the left and right sides of the OLED panel (133).

[0064] In this experiment, as shown in FIG. 7b, the healing results by date were observed up to 9 days after attaching the medical device (100) to the back of a mouse. That is, starting from 3 days later, the color of the wound area changed as it healed, and after removing the transparent dressing film (190), it was confirmed that the wound gradually became smaller.

[0065] Figure 8 shows these results as a graph of wound size by date after light irradiation.

[0066] Figure 8 is a graph of wound size by date after light irradiation to show that the present invention is effective for wound healing.

[0067] Referring to FIG. 8, when comparing the relative diameter size (au) with the control group (CTL), it was confirmed that the wound healed fastest when the medical device (100) of the present invention was used to irradiate light for 20 minutes every day.

[0068] In the medical device (100) of the present invention as such, the circuit (132-5) of the flexible printed circuit board (132) is such that the red light emitting OLED panel (133) emits red light with a wavelength of 600 to 700 nm at a low output (e.g., 2 mW / cm²) 2 From ) to high output (e.g., 25mW / cm² 2 The current flowing through the red light-emitting OLED panel (133) can be controlled to output up to ). Accordingly, the back cover (120) can be brought into contact with the human body to assist in cell regeneration and activation for healing wounds on the human body by the red light from the red light-emitting OLED panel (133).

[0069] To this end, although the voltage of the flexible battery (131) is fixed at 2~4V, etc., the resistance value of a predetermined variable resistor is varied according to the control of the circuit (132-5) of the flexible printed circuit board (132) to control the current flowing to the red light-emitting OLED panel (133) so that the intensity of the light is low output (e.g., 2mW / cm²). 2 From ) to high output (e.g., 25mW / cm² 2The voltage can be adjusted up to ). The variable resistor may be provided on a flexible printed circuit board (132), and the circuit (132-5) can adjust the intensity of the light as set by the user using a button or switch (not shown) provided on the outside of the combination of the front cover (110) and the back cover (120).

[0070] Furthermore, if necessary, the user can use a button or switch (not shown) provided on the outer side of the combination of the front cover (110) and the back cover (120) to set the time during which the resistance value is maintained and the period of on / off light generation during the time during which the resistance value is maintained and the period during which the resistance value is maintained and the period during which the light generation is maintained and the period during which the resistance value is maintained and the period during which the resistance value is maintained and the period (132-5) of the flexible printed circuit board (132) can be controlled to irradiate the intensity of the corresponding light on the time during which the resistance value is maintained and the period during which the resistance value is maintained and the period during which the resistance value is maintained and the period during which the resistance value is maintained and the period during which the resistance value is maintained and the period during which the light generation In some cases, the user may configure the system to allow setting the duty cycle (e.g., 30%, 40%, 50%, 60%, etc. based on on-time) using a button or switch (not shown) provided on the outside of the combination of the front cover (110) and the back cover (120).

[0071] As described above, the human body-attachable medical device (100) using an organic light-emitting diode according to the present invention utilizes a red wavelength, which is harmless to the human body, particularly 600 to 700 nm (preferably 645 nm), to apply to the wound to promote metabolic activity and induce cell proliferation, thereby allowing the wound to heal quickly in the early stages through cell regeneration and activation, and reducing the possibility of scar formation. Since the present invention is manufactured in a human body-attachable form different from existing wound healing devices, there is no need to visit a hospital, so it offers excellent usability and convenience, and a healing effect can be achieved with only a short period of irradiation. The intensity of the light source and the treatment time can be freely adjusted, and through the adjustment of intensity and time, it is a human body-attachable medical device that can be used not only for wound healing but also for various diseases such as pain relief. Furthermore, it is the first to utilize an organic light-emitting diode light source, enabling uniform irradiation and allowing it to be manufactured as a flexible platform. Above all, since it is very safe from the harmful effects of blue light, it is possible to provide a medical device that ensures photobiological safety.

[0072] In addition, the human body-attachable medical device (100) using an organic light-emitting diode (OLED) according to the present invention was verified to have rapid wound healing in the preclinical stage, and it was verified that the wound heals quickly under conditions of a rapid irradiation time (20 minutes). The present invention is a medical device using an organic light-emitting diode light source that can be freely attached to a wounded area to allow the wound to heal quickly through uniform light irradiation, and can be used continuously through a rechargeable method. Furthermore, it is manufactured in a form that is attached to the human body, providing a new medical device that is free from the constraints of time and space. In addition, to overcome the limitations of existing phototherapy, an OLED surface light source capable of being manufactured in various form factors to enable uniform irradiation was developed and utilized, rather than a laser or general LED light source. It was also developed in a flexible form so that the user can freely attach and receive treatment without visiting a hospital. Furthermore, to enable continuous use rather than being a disposable product that is used once and then discarded, a battery charged via a charging terminal is built in to operate.
