Description

[Technical Field]

[0001] The present invention relates to a gum blood circulation promoting device, and more specifically to a gum blood circulation promoting device that can irradiate the gums with near-infrared light and / or infrared light to promote blood flow, improve metabolism, and activate cells. [Background technology]

[0002] As shown in Patent Document 1, the present applicant has proposed a device that irradiates the skin with near-infrared light and applies minute vibrations. Near-infrared light has a wavelength of 780 to 2500 nm, and near-infrared light with a wavelength of 800 to 945 nm in particular is not absorbed by water in the skin or hemoglobin in the blood, so it penetrates the skin well. On the other hand, red visible light has a wavelength of 640 to 770 nm, and although it does not penetrate as deeply as near-infrared light, it gives a warm feeling when irradiated to the skin, similar to near-infrared light. Near-infrared light is invisible, but red visible light is visible.

[0003] Patent Document 2 discloses a gum warmer that can warm the gums. This gum warmer is in the form of a mouthpiece equipped with a heat storage material, which is heated in advance with a heater and then inserted into the oral cavity of the human body for use.

[0004] [Patent Document 1] Publication No. 3229657 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-10542 Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide a gum blood circulation promoting device that can come into contact with the gums, warm the gums, promote blood flow, and activate cells. [Means for solving the problem]

[0006] The gum blood circulation promoting device according to the present invention comprises a support member made of a metal plate or an optically opaque resin, on which a plurality of LEDs are mounted in a row; a base member in which the support member is embedded and which has rounded corners at its longitudinal end to form a strip-like shape and which can be inserted into the oral cavity; and a coaxial connector which supplies DC voltage to the LEDs, wherein the LEDs emit near-infrared light and / or red visible light, and at least the surface of the base member facing the LEDs is transparent.

[0007] The base member is characterized in that a flexible core material is provided inside the base member to maintain the bent shape of the base member.

[0008] The base member may include two base members, and a connecting band may be further provided to connect the two base members in a parallel state.

[0009] Another gum blood circulation promotion device according to the present invention comprises a support member made of a metal plate or an optically opaque resin, on which a plurality of LEDs are mounted in a row; a base member in which the support member is embedded and which has rounded corners at both ends in a U-shaped curve that follows the gums, and which can be inserted into the oral cavity; and a coaxial connector that supplies DC voltage to the LEDs, wherein the LEDs emit near-infrared light and / or red visible light, and at least the surface of the base member facing the LEDs is transparent.

[0010] The device further includes a USB connector that supplies DC voltage from an external power source to the coaxial connector. [Effects of the Invention]

[0011] According to the gum blood circulation promoting device of the present invention, (a) The thermal effects of near-infrared light and visible red light can slowly warm the gums, promoting blood flow, improving metabolism, relieving pain, and activating cells. (b) The base member is formed in a strip shape, making it easy to insert into the oral cavity. Because it is strip-shaped, it can be curved to make contact with the outside or inside of the gums. It can also be placed on the gums after a tooth has been extracted. The corners at the tip of the length of the base member are rounded, so it will not hurt the skin inside the mouth even if it comes into contact with it. Because it is a strip-shaped, oblong shape, it is suitable for locally warming the gums. (c) The surface of the base member facing the LED is made transparent, allowing the LED light emitted inside the base member to pass through to the outside. (d) When both a near-infrared LED and a visible red LED are installed, the visible red light is emitted when power is supplied, so it is possible to confirm at a glance that power is being supplied. (e) The support member for the LED is made of a metal plate or a light-opaque resin, so the LED can be hidden from view from the back of the support member on which it is mounted. If the base member is turned in the opposite direction, the light can be prevented from entering the eyes.

[0012] Since a core material is provided inside the strip-shaped base member, the base member is flexible and easily bent, but it can maintain its bent shape and come into contact with the gums.

[0013] A connecting band is provided to connect the two strip-shaped base members in parallel, so the base members will not come apart when inserted into the mouth. There is no need to hold the two base members in place with your hands or tongue.

[0014] According to another gum blood circulation promoting device of the present invention, (a) The thermal effects of near-infrared light and visible red light can slowly warm the gums, promoting blood flow, improving metabolism, relieving pain, and activating cells. (b) The base member is shaped like a U-shape that follows the gum line, so when the LEDs are placed inside the U-shape, they can warm the upper and lower outer gums. When the LEDs are placed outside the U-shape, they can warm the upper and lower inner gums. The corners on both ends of the length of the base member are rounded so they will not hurt the skin inside the mouth even if they come into contact with it. The U-shaped base member is suitable for warming both the upper and lower gums at the same time. (c) The surface of the base member facing the LED is made transparent, allowing the LED light emitted inside the base member to pass through to the outside. (d) When both a near-infrared LED and a red visible light LED are installed, the red visible light is emitted when power is supplied, so power supply can be confirmed at a glance. (e) The support member for the LED is made of a metal plate or a light-opaque resin, so the LED can be hidden from view from the back of the support member on which it is mounted. If the red visible light is too bright, you can prevent the light from entering your eyes by turning the base member in the opposite direction.

[0015] Since the DC voltage from the external power source is supplied to the coaxial connector via the USB connector, it can be made smaller and easier to use than outlets that have a circuit that converts AC to DC voltage. [Brief explanation of the drawings]

[0017] Hereinafter, the gum blood circulation promoting device of the present invention will be described in detail with reference to the drawings. [Example]

[0018] FIG. 1 is a diagram of a gum blood circulation promoting device 100 according to the present invention. A power outlet 1 is connected to a commercial power source and includes an internal AC / DC converter. In this embodiment, 100V AC is converted to 5V DC. A branch terminal 2 is connected to the electrical wires extending from the power outlet 1, splitting the power into two systems. Coaxial connectors 3 are attached to the two electrical wires extending from the branch terminal 2, and the coaxial connectors 3 transmit 5V DC to two strip-shaped base members 4, 4, each made of flexible resin. The strip-shaped base member 4 is equipped with multiple LEDs 6 arranged in a row. The LEDs 6 emit near-infrared light and red visible light, which are expected to have a thermal effect. The base member 4 is strip-shaped, approximately 1 cm wide, 10 cm long, and 5 mm thick. Twelve near-infrared LEDs 6a and red visible LEDs 6b are arranged alternately in a row on the strip-shaped base member 4. The electric wire 11 from the outlet 1 to the branch terminal 2 is approximately 1.25 m long. The distance from the branch terminal 2 to the coaxial terminal 3 is approximately 20 cm, and the distance from the coaxial terminal 3 to the base members 4 is approximately 10 cm. The base member 4 is inserted into the oral cavity and irradiates near-infrared light and red visible light toward the gums. In this embodiment, the LED 6 is equipped with near-infrared light and red visible light, but this is not limiting, and the LED 6 may be equipped with either near-infrared light or red visible light.

[0019] Figure 2 is a cross-sectional view of the base member 4 shown in Figure 1 taken along the line AA. The base member 4 is a transparent member made of silicone rubber or thermal plastic elastomer (TPE). Silicone rubber and thermoplastic elastomer (TPE) can be washed with water and are safe to insert into the mouth. Because they are flexible and soft, they do not damage the skin inside the mouth. The base member 4 has an LED 6 and a resistor 7 mounted on a support member 8 embedded therein. The support member 8 is a thin metal plate or a light-impermeable resin member. The support member 8 corresponds to a circuit board and mounts the LED 6 and resistor 7. Because the base member 4 is flexible and soft, it can be bent with little force. A flexible core member 10 extending longitudinally is provided within the base member 4. For example, a thin aluminum plate or a thin silicone resin plate can be used for the core member 10, which allows the base member 4 to maintain its bent state. The base member 4 was transparent on the front side of the LED 6, and mixed with a coloring material on the back side of the LED 6 so as to block light.

[0020] Figure 3 is a circuit diagram of the LED in Figure 1. Three LEDs 6 are connected in series and a resistor 7 is connected. Three LEDs 6 connected in series are connected in parallel for a total of 12 LEDs. Two base members 4 are provided, so there are 24 LEDs 6 in total. Note that when outlet 1 is plugged into an external outlet, power is supplied to the LEDs 6; however, instead, a power on / off switch can be provided in branch terminal 2 so that power is supplied to the LEDs 6 when the switch is turned on. Note that if a power indicator is provided in branch terminal 2, even if all of the LEDs 6 emit near-infrared light, the power indicator will light up to indicate that power is supplied.

[0021] FIG. 4 shows the bent state of the base member 4. When irradiating the outside of the gums with light from the LEDs 6, bend the base member 4 so that the LEDs 6 are on the inside of the curve, as shown in FIG. 4(A). When irradiating the inside of the gums with light from the LEDs 6, bend the base member 4 so that the LEDs 6 are on the outside of the curve. As shown in FIG. 4(B), a portion of the left end can be curved using the core material 10. Even without the core material 10, the strip-shaped base member 4 can be bent, so it can be pressed against the gums with the hand or cheek. The corners of the tip of the base member 4 in the longitudinal direction are rounded, as shown by the dotted circle, so that it does not hurt when it comes into contact with the skin inside the mouth. Both longitudinal ends can also be rounded.

[0022] Figure 5 is a photograph of the base member in Figure 1 when power is supplied and red visible light is turned on. Six LEDs 6b are lit, and the near-infrared LED 6a is not visible to the naked eye, even though it is energized.

[0023] Figure 6 shows an example in which two base members 4, 4 are connected vertically with a connecting band 12. When warming the front sides of the lower and upper gums of the oral cavity together, the connecting band 12 with two holes connects both ends of the base members 4, 4. This allows the base members 4, 4 to be connected vertically in parallel. The base members 4, 4 can be made into a single wide base member. The connecting band 12 in Figure 6 is configured with a ring, a connecting material, and another ring lined up in the vertical direction.

[0024] Figure 7 shows an example of two base members 4, 4 connected front to back with a connecting band 12. When warming the front and back of the lower gums of the oral cavity together, both ends of the base members 4, 4 are connected with a connecting band 12 having two holes. The base members 4, 4 can be connected front to back in a parallel position. It can be used by placing it over the teeth of the lower gums. The connecting band 12 in Figure 7 is configured with a ring, connecting material, and another ring lined up in the front to back direction, with the two rings arranged at right angles to the connecting material. [Example]

[0025] FIG. 8 is a diagram of another gum blood circulation promoting device 100 according to the present invention. The USB connector 13 is a typical USB connector with different connector shapes, and several commonly used shapes were prepared. The USB connector 13 has a 5V power pin in addition to a signal pin, and this 5V is used. The DC 5V from the multiple USB connectors 13 is combined into one at the power supply coupling unit 9 and sent to the coaxial connector 3. The DC 5V is then sent from the coaxial connector 3 to the LEDs 6 arranged in two rows on the base member 4. The base member 4 is formed in a U-shaped curve. In Example 2, a total of 16 LEDs, consisting of near-infrared LEDs 6a and red visible LEDs 6b, are arranged in 8 x 2 rows inside the U-shaped curve. The near-infrared LEDs 6a and red visible LEDs 6b are alternately arranged in a row on the base member 4, forming two rows, one above the other. The U-shaped base member 4 of this embodiment is convenient for warming both the lower and upper gums by inserting it from the front of the oral cavity and pressing it against the lower and upper gums. As shown by the area circled by dotted lines, both ends of the base member 4 are rounded without any corners, so that even if it comes into contact with the skin inside the mouth, it will not injure the skin. There are also recesses above and below the center of the base member 4 to prevent it from coming into contact with the midline inside the mouth.

[0026] The circle in Figure 8 shows the AA cross section of the base member 4. The base member 4 is a transparent member made of silicone rubber or thermoplastic elastomer (TPE). An LED 6 and a resistor 7 mounted on a support member 8 are embedded inside the base member 4. The support member 8 is a light-impermeable resin member. The base member 4 is elastic and soft, so it is gentle on the skin.

[0027] As shown in Figure 8, the base member 4 does not have a core material 10. The support member 8 has thickness and maintains a U-shaped curved shape. Both ends of the base member 4 can be widened or narrowed by about 1 cm, but one base member 4 cannot accommodate the different gums of adults and children, so three base members 4 with large, medium, and small U-shaped curves are provided. In addition, in the configuration shown in Figure 8, power is supplied to the LED 6 when the USB connector 13 is inserted into an external USB connector, but instead, an on / off switch for the power supply coupling unit 9 may be provided so that power is supplied to the LED 6 when the switch is turned on.

[0028] Figure 9 is a diagram showing a modification of Example 2. In the gum blood circulation promoting device 100 shown in Figure 9, the base member 4 is formed in a U-shaped curve, and 16 LEDs 6 are arranged on the outside of the U-shaped curved base member 4. This is convenient when inserting the base member 4 from the front to the back of the oral cavity to warm the inside of both the lower gums and the upper gums.
