Hereinafter, an analgesic patch whose activity is enhanced by light, which is one embodiment of the present invention, will be described in detail with reference to the drawings.

1 is a front view of an analgesic patch 100 whose activity is enhanced by light, which is an embodiment of the present invention. 1, the analgesic patch 100 according to an embodiment of the present invention has a rectangular shape as a whole, and has a first tapered portion 101 on the long side and a second tapered portion 102 on the short side . Here, the first tapered portion 101 is formed at an obtuse angle, and the second tapered portion 102 is formed at an acute angle to have a butterfly shape as a whole. Accordingly, when the analgesic patch 100 is attached to the place of use, the shapes of the first and second tapered portions 102 can be configured to easily cope with the movement due to the contraction and relaxation of the muscle. Furthermore, the analgesic patch, which is one embodiment of the present invention, enhances feeling by using fabric fiber as a substrate in consideration of contraction and relaxation of muscles. This will be described in detail with reference to FIG.

1, a light diffusion sheet 120 is attached to a light emitting sheet 110 including an optical element arranged in a matrix form in the analytical patch according to the present invention, (130) is applied. Accordingly, the light generated in the optical element passes through the light-diffusing sheet 120 through the chemical agent layer 130, and irradiates the attachment region of the wearer. The light at this time is a photon therapy light that activates the epidermal layer or the epidermal layer. Accordingly, since the drug layer 130 adheres to the skin (the affected part) in a state in which the dermal layer and the skin layer are activated, the drug component of the drug layer 130 is more easily absorbed to the skin.

Hereinafter, the overall structure of the analgesic patch 100 whose activity is enhanced by light, which is one embodiment of the present invention, will be described in more detail through an exploded perspective view of FIG.

2, the analytical patch 100 whose activity is enhanced by light, which is one embodiment of the present invention, includes a light emitting sheet 110, a light diffusion sheet 120, a medicine layer 130, a release paper 140 A heat-radiating sheet 150, and an adhesive sheet 160, as shown in FIG.

The light emitting sheet 110 may include a flexible substrate 111 and an optical element 113 attached to the flexible substrate 111. As the flexible substrate, a flexible fiber fabric layer may be used. This is because when the analgesic patch 100 according to the present invention is attached to muscle, it has to have a very high ductility in accordance with relaxation of muscle contraction. It is a structure that a metal pattern layer is formed on a substrate called a fiber cloth layer, It is possible to maintain the same ductility as the fiber.

On the other hand, the optical element 113 is a component for irradiating near-infrared light stimulating the skin layer and far-infrared light stimulating the dermal layer. To this end, the optical element 113 includes a first optical element 113a and a second optical element 113b, and the first optical element 113a and the second optical element 113b may be alternately installed . Here, the first optical element 113a may have a wavelength band of 600 to 780 nm, and the second optical element 113b may have a wavelength band of 780 to 900 nm. The structure of the light emitting sheet 110 of the analgesic patch 100 according to the present invention will be described in more detail with reference to FIG.

The light diffusion sheet 120 is attached to the front surface of the light emitting sheet 110 to function to uniformly irradiate the phonon therapy light generated from the optical element 113 to the chemical agent layer 130, In order to mitigate the heat generated in the optical element of the light emitting diode (LED). To this end, the light diffusion sheet 120 may be made of a light transmitting resin material, and may be made of transparent silicon or a transparent urethane material including a light diffusing material such as a silicon powder. The light-diffusing sheet 120 has a concentric corrugation 123 as shown. The corrugated portion 123 serves as a light guide to uniformize the photon therapy light emitted from the optical element. The surface of the light diffusion sheet 120 may be embossed to scatter the photon therapy light so as to give a proper stimulus to the skin, as well as to enhance the binding property with the medicament layer 130.

On the other hand, in the light diffusion sheet 120, the optical element grooves 121 corresponding to the optical elements of the light emitting sheet 110 are formed in a matrix form. By providing the optical element groove 121 in this way, the loss of the photon therapy light of the optical element 113 can be minimized, so that the skin irritation can be more effectively guided. Further, by the above-described wrinkle portion 123 By maintaining the uniformity of the photon therapy light, it is possible to safely maximize the skin irritation of the light.

The light diffusion sheet 120 is made of a silicone or urethane material having a high latent heat so as to promote a proper thermal effect on the chemical agent layer 130 and the affected part so as to further promote skin absorption of the chemical substance in the chemical agent layer 130 .

The heat-radiating sheet 150 is attached to the rear surface of the light-emitting sheet 110, and functions to heat the heat of the light-emitting sheet 110 to the outside. At this time, the heat-radiating sheet 150 may be formed of a fiber fabric layer, and the fiber fabric layer may include a plurality of outer fiber bundles formed orthogonally and an inner fiber bundle formed in a space formed by the outer fiber bundles . The heat-radiating sheet 150 is made of fibers and is configured to cope with relaxation of muscle contraction, and metal powder may be included to maximize heat dissipation efficiency. This will be described in more detail in FIG.

A chemical agent layer 130 is formed on the front surface of the light diffusion sheet 120. The medicament layer 130 may be a gel-type layer having a medicinal component containing an analgesic component, a solid layer, or a fluidized bed. The releasing paper 140 is attached to the front surface of the medicine layer 130 so that the medicine layer 130 is exposed to the outside air to prevent the moisture from disappearing or the medicine component from being lost and its efficacy being degraded.

On the other hand, the heat-radiating sheet 150 can function as an adhesive sheet as its elongated body, or can adhere the adhesive sheet 160 to the back surface or the entire surface of the heat-radiating sheet 150 separately. The adhesive sheet 160 is coated with an adhesive component and functions to attach the analgesic patch 100 according to the present invention to the affected part of the user.

Hereinafter, the structure of the heat radiation sheet and the light emitting sheet will be described in detail with reference to FIG.

Fig. 3 is a cross-sectional view showing a state in which a light emitting sheet and a heat radiation sheet of an analgesic patch whose activity is enhanced by light, which is an embodiment of the present invention, are combined. 6, a flexible fiber fabric layer 111, a metal pattern layer 114, an insulating resin adhesive layer 112, an optical element 113, and a heat radiation sheet 150 are shown in Fig. Here, the flexible fiber fabric layer 111, the metal pattern layer 114, the insulating resin adhesive layer 112, and the optical device 113 are included in the light emitting sheet 110.

The flexible fiber fabric layer 111 serves as a substrate of the light emitting sheet 110. The analgesic patch according to an embodiment of the present invention can be attached to the affected part of the wearer with good ductility. A fiber-based substrate is used instead of a simple flexible substrate. On the flexible fiber fabric layer 111, an insulating resin adhesive layer 112 and a metal pattern layer 114 are formed thereon. The flexible fiber fabric layer 111 may be formed of a plurality of fiber bundles that are orthogonal to each other. Fibers are natural or artificial linear objects that are long, thin, and bendable. The plurality of fibers may be woven by a weaving method to be a woven fabric or may be knitted by a knitting method to be a knitted fabric. The plurality of fibers may comprise carbon fibers (which are constituent elements of a bundle of carbon filaments). Carbon (carbon) fiber is a fibrous carbon material having a mass content of carbon element of 90% or more. The carbon fiber is a fibrous type organic precursor material made from polyacrylonitrile, a petroleum coal hydrocarbon residue pitch or rayon, or a precursor, meaning a fiber obtained by pyrolyzing a substance before carbonization in an inert atmosphere do.

The specific heat of the carbon fiber is 0.7 to 0.9 kJ / Kg · K (average value from room temperature to 70 ° C), which is approximately the same as 0.5 to 1.0 kJ / Kg · K (from room temperature to 100 ° C) of iron, aluminum and titanium alloy, Of 1.5 to 2.0 kJ / kg · K). The specific heat of the carbon fiber increases as the temperature increases, and the average value from room temperature to 1,500 ° C is 1.7 kJ / Kg · K. The thermal conductivity of carbon fiber is 390 ~ 750 W / m · K, 1.5 ~ 2 times that of metal.

Carbon fiber has various products depending on performance, form, manufacturing method and starting material. The carbon fiber includes a small tow having 1,000 to 12,000 unit fibers in one bundle and a large tow having 48,000 to 320,000 unit fibers.

The insulating resin adhesive layer 112 is a component for allowing the metal pattern layer 114 to adhere to the flexible fiber fabric layer 111. Such an insulating resin adhesive layer 112 may include a ceramic powder that can enhance thermal conductivity and have sufficient ductility with the resin.

The resin may be a thermosetting or thermoplastic resin and may include at least one of acrylic resin, silicone resin, urethane resin, polyimide resin, epoxy resin, and PEEK resin. These types of resins are suitable for conducting heat generated from the optical element 113 mounted on the metal pattern layer 114, since they have excellent adhesion, high ductility and high thermal stability. The ceramic powder may be formed to include at least one of aluminum oxide, aluminum nitride, titanium dioxide, and silicon dioxide. These ceramic powders are suitable for conducting heat generated from the optical element 113 mounted on the metal pattern layer 114 in that they have high thermal conductivity and high electrical insulation. The ceramic powder may be mixed with 30 to 80% by weight of the resin. If the amount of the ceramic powder is less than 30% by weight of the resin, the heat-conductive ability of the insulating insulating resin adhesive layer 112 is insufficient, and thermal conduction from the metal pattern layer 114 to the flexible fiber fabric layer 111 may become a bottleneck . If the ceramic powder is more than 80% by weight, the adhesion between the insulating resin adhesive layer 112 and the metal pattern layer 114 or the soft fiber fabric layer 111 may be problematic.

The metal pattern layer 114 is a layer in which a thin plate (metal foil) made of a metal has a certain pattern. Here, the metal foil may be formed of a copper material. And the optical element 113 is attached on the metal pattern layer 114. As such optical element 113, a flip-on-chip light emitting diode may be used.

The optical element 113 irradiates photon therapy light including near-infrared light and far-infrared light. That is, the first optical element 113a and the second optical element 113b are alternately installed. Here, the first optical element 113a has a wavelength band of 600 to 780 nm and the second optical element 113b has a wavelength band of 780 to 900 nm, so that not only the skin layer but also the dermal layer are activated, Be able to penetrate well into

On the other hand, a CNT layer having a good thermal conductivity may be further added between the flexible fiber fabric layer 111 and the heat-radiating sheet 150. This CNT layer is formed in order to allow the heat generated from the optical element 113 to be conducted to the second woven fiber layer sooner. On the other hand, if the metal pattern layer 114 is made of copper or aluminum having excellent ductility, the heat radiation effect can be maximized while the overall ductility is increased.

The lower portion of the heat-radiating sheet 150 attached to the flexible fiber fabric layer 111 is exposed to the atmosphere as it is. The surface thus exposed may be referred to as a heat releasing surface.

With this configuration, one surface of a plurality of interwoven fibers of the heat-radiating sheet 150 is directly exposed to the atmosphere, so that the surface area of a portion of the heat-radiating sheet 150 in contact with the atmosphere becomes extremely high.

Thereby heat generated by the optical element 113 mounted on the metal pattern layer 114 passes through the metal pattern layer 114, the insulating resin adhesive layer 112 and the flexible fiber fabric layer 111 in this order, Heat can be effectively radiated to the atmosphere after being transmitted to the heat-radiating sheet 150. In this heat dissipation process, the convection action of the atmosphere in contact with the heat-radiating sheet 150 enhances the heat-radiating function more effectively by the relatively large surface area of the heat-radiating sheet 150.

The heat dissipation sheet 150 includes an inner fiber bundle 151 arranged in parallel to each other, a first outer fiber bundle surrounding the outer surface of the inner fiber bundle 151 in a first sine wave shape, And an outer fiber bundle (152) including a second outer fiber bundle which intersects the outer bundle of the first outer fiber bundle in a second sine wave shape having an angle of 180 ° and encloses the outer surface of the inner fiber bundle (151) have.

At this time, the inner fiber bundle 151 has a higher thermal conductivity than the first and second outer fiber bundles.

Such a heat-radiating sheet, by its function, can include a heat-converging layer and a heat-dissipating layer. The heat converging layer is an upper layer of the heat-radiating sheet 150, and is a portion that directly converges heat transmitted from the soft fiber fabric layer 111. [ On the other hand, the heat dissipating layer is a portion exposed to the outside, and dissipates the heat converged in the heat converging layer to the outside.

At this time, the thermal conductivity of the inner fiber bundle 151 arranged at the center becomes higher than that of the first and second outer fiber bundles 152. As a result, the heat in the heat convergence layer is transferred to the inner fiber bundle that is more excellent in thermal conductivity and the heat in the inner fiber bundle 151 is transmitted to the first and second outer fiber bundles 152 So that the heat radiation efficiency is excellent. In other words, at this time, the heat convergence layer is capable of convergence because the heat advances from the broad curved surface toward the center of the curved surface. On the contrary, the heat dissipating layer radiates heat through the broad curved surface at the center, so that the heat dissipation becomes possible.

The inner fiber bundles 151 are arranged so as to extend in a direction perpendicular to the drawing sheet on which the drawing is drawn. The inner fiber bundles 151 may be arranged so as to be parallel to each other.

The first and second outer fiber bundles 152 surround the outer surface of the inner fiber bundle 151 to form a closed curve. Specifically, in this embodiment, the outer fiber bundle 152 forms a generally elliptical closed curve with respect to the inner fiber bundle 151 and surrounds the outer surface of the inner fiber bundle 151. The first outer fiber bundle and the second outer fiber bundle 151 are arranged so as to cross each other and form a sine wave having a phase opposite to that of each other. In view of the shape of the outer fiber bundle 151 having a sine wave shape, the first outer fiber bundle may be referred to as a first sine wave fiber bundle, and the second outer fiber bundle may be referred to as a second sine wave fiber bundle. .

Since the heat-radiating sheet 150 described above has higher thermal conductivity than the flexible fiber fabric layer 111 and has no problem even if it has electrical conductivity, the metal powder is included in the heat-radiating sheet 150 to further increase the thermal conductivity . Since the heat-radiating sheet 150 described above has higher thermal conductivity than the flexible board 111 and has no problem even if it has electrical conductivity, the metal powder is included in the heat-radiating sheet 150 to further increase the thermal conductivity .

Hereinafter, the mounting of the power supply module for supplying power to the light emitting sheet in the analytical patching in which the activity is enhanced by light, which is one embodiment of the present invention, will be described with reference to FIG.

4 is a rear view of a light emitting sheet of an analgesic patch whose activity is enhanced by light, which is an embodiment of the present invention. 4, a power supply source 115 for supplying power to the light emitting sheet and a control circuit 117 for controlling the current applied from the power supply source 115 may be provided on the rear surface of the light emitting sheet. Here, the power supply source 115 may include a battery 115a attached on the light emitting sheet, and a small battery such as a mercury battery may be used in consideration of the overall weight and design.

According to the above configuration, when the wearer wears the analgesic patch on the wearing area, the power supply 115 supplies power to the light emitting sheet through the control circuit 117. [

In the present invention, a fiber cloth layer is used as the substrate of the light emitting sheet. However, the present invention is not limited to this, and a flexible substrate made of a plastic material can be used. This will be described with reference to FIG.

FIG. 5 is a cross-sectional view for explaining another example of the light emitting sheet in the analgesic patch according to one embodiment of the present invention, wherein FIG. 5 (a) is an example thereof and FIG. 5 (b) is another example.

5, the light emitting sheet of another example of the light emitting sheet corresponds to the soft substrate 11 ', the metal pattern layer 12, the light emitting diode element 14, the optical element 113 above, The second optical element is the same as the second optical element), and a metal reinforcing plate 15. The metal reinforcing plate 15 may be a metal plate or a metal plate. Here, the metal pattern layer 12 and the light emitting diode element 14 are the same constituent elements as those described above, so that a description thereof will be omitted.

The flexible substrate 11 'is a substrate having sufficient flexibility that can be bent so as to sufficiently cope with relaxation of the muscles. Here, the flexible substrate 11 'is made of fiberglass reinforced epoxy laminates (FR4), and its thickness may be 0.1 mm to 0.5 mm. When the thickness is less than 0.01 mm, there is a risk of fraying due to warping depending on the face shape. If the thickness is 0.05 mm or more, there is a problem that warpage does not occur due to muscle relaxation shrinkage.

On the other hand, the rigidity of the flexible substrate 11 'becomes a problem. That is, as the flexible substrate 11 'is warped, cleavage of the substrate itself may occur. In order to reinforce this, the metal reinforcing plate 15 is attached to the lower surface of the flexible substrate 11 '.

The metal reinforcing plate 15 is made of copper having excellent ductility, and the metal reinforcing plate 15 can have a weight of 0.5 to 1 ounce. Since copper has excellent ductility and excellent thermal conductivity, it not only has an effect of rapidly radiating heat generated from the light emitting diode element 14 to the lower surface side of the substrate, but also has a cleavage effect . At this time, when it is configured to be 0.5 ounces or less, the reinforcing function is insufficient, and if it is 1 ounce or more, the ductility of the metal reinforcing plate 15 itself is insufficient, and it becomes impossible to cope with relaxation of muscle contraction.

On the other hand, the metal reinforcing plate 15 may be provided with a metal reinforcing plate 15 as a whole on the lower surface of the flexible substrate 11 'as shown in FIG. 6 (a) A metal reinforcing plate 15 'may be provided for each surface between the metal pattern layers 12 in the lower surface of the substrate 11'.

According to an embodiment of the present invention having the above-described configuration, since the chemical layer is attached to the user's skin in a state where light for activating the skin or dermis layer, such as infrared light or near-infrared light, , The skin absorption of the drug component of the applied drug layer can be made more smoothly.

Further, according to the embodiment of the present invention, since the analgesic patch has sufficient ductility in accordance with the relaxation and contraction of the muscles of the wearer, it is possible to stably attach the analgesic patch.

In addition, according to one embodiment of the present invention, since the heat during light irradiation for a long time is appropriately maintained, a warm massage effect is also performed, so that the skin can be absorbed while preventing the burn.

The structure and method of the above-described embodiments are not limited to be applied to the analgesic patch whose activity is enhanced by the light described above. The embodiments may be configured so that all or some of the embodiments may be selectively combined so that various modifications may be made.
