Description

Technical Field

[0001] The present invention relates to an eyelash extension system, and more specifically to a system comprising tweezers with a light irradiation function for eyelash extension using a photocurable glue.

Background Art

[0002] In recent years, eyelash extensions, in which artificial hairs are added to individual natural eyelashes, have been popular as a beauty treatment for women. Eyelash extension is a beauty treatment that bonds one (or more) artificial hair to a single natural eyelash with a special glue (adhesive) to lengthen the eyelashes and make the eyes look more defined.

[0003] An outline of a conventional eyelash extension treatment method will be described with reference to FIG. 7. Typically, the recipient receives the treatment in a supine or reclined position, and protective tape, patches or the like are applied around the eyes, which are omitted in FIG. 7 for simplicity of explanation. As shown in FIG. 7(a), with tweezers held in the dominant hand (the right hand in this example), a single artificial hair 15 is picked up from a bundle of artificial hairs (not shown), and its root is lightly brought into contact with a prepared glue (not shown) to attach the glue to the root. Next, with another pair of tweezers held in the hand opposite the dominant hand (the left hand in this example), the left and right eyelashes are moved outward, leaving only the natural eyelash 20 to which the artificial hair 15 is to be attached, to prevent unnecessary contact. As shown in FIG. 7(b), the artificial hair 15 and the natural eyelash 20 are bonded such that they overlap each other over a certain length. Conventionally, cyanoacrylate-based instant adhesives that cure by reacting with moisture have been used as glue for eyelash extensions. In the state shown in FIG. 7(b), after holding for about 10 to 30 seconds, the tweezers are released, and the technician may move on to treating the next eyelash, or alternately perform treatment on one eye at a time to allow further curing. For this reason, attaching tens to more than a hundred artificial hairs in a single treatment takes several tens of minutes to more than one hour.

[0004] To shorten treatment time and reduce discomfort for the patient, the use of light-curing glue for eyelash extensions has been proposed (for example, Patent Documents 1-4). These documents describe a process in which artificial lashes are attached to natural eyelashes using light-curing glue, and then the glue is cured by irradiation with ultraviolet or visible light. This results in a faster curing speed compared to conventional procedures using instant adhesives, and consequently, a shorter treatment time. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2011-87658 [Patent Document 2] Japanese Patent Publication No. 2017-119935 [Patent Document 3] Japanese Patent Publication No. 2019-56095 [Patent Document 4] Japanese Patent Publication No. 2020-7663 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, conventional systems using light-curing glues all irradiate the patient's eyelashes with ultraviolet or visible light, but their structure does not allow the light source or light emitter to be placed too close to the adhesive area of ​​the eyelashes. Therefore, a strong light source is required to obtain the necessary polymerization reaction, which is not only difficult to miniaturize and costly, but can also be harmful to both the practitioner and the patient. If the light source or light emitter is brought closer to the patient's eyelashes in this case, it obstructs the practitioner's work area and requires the practitioner to frequently switch between tweezers and the LED irradiation device, which reduces work efficiency. In addition, conventional systems all irradiate the patient's eyelashes and eyelids from above, and the light is directed towards the patient's eyes.

[0007] In view of the above-mentioned problems, the present invention aims to provide an eyelash extension system that dramatically reduces the treatment time, can be constructed at low cost, and also protects the eyes of both the practitioner and the patient. [Means for solving the problem]

[0008] The present invention relates to an eyelash extension system using a light-curing glue, characterized by comprising: a tweezers body having two elongated members with tapered / thinned tips that converge at the base end; a light source for curing the light-curing glue; a power supply unit for driving the light source; and an optical path for emitting light from the light source from the tip portion of at least one of the elongated members.

[0009] In the eyelash extension system of the present invention, it is preferable that the optical path is configured to emit light from the light source in a direction substantially perpendicular to the long axis of the elongated member and toward the inside of the tweezers body.

[0010] Furthermore, it is preferable that the power supply unit includes a control unit that causes the light source to blink at a predetermined cycle. It is also preferable that the tip portion of the elongated member of the tweezers body is replaceable.

[0011] Furthermore, it is preferable that a transparent cover is provided at the light emission port at the end of the optical path to prevent the glue from entering the optical path.

[0012] Furthermore, it is preferable that the light source has at least two levels of switching between irradiation intensities, or that it includes two or more light sources with different irradiation intensities. Also, the power supply unit and the tweezers body can be configured separately and connected by wiring.

[0013] Furthermore, it is preferable to provide a detachable light shield on the tweezers body to protect the practitioner's eyes during use. Additionally, it is preferable to provide a flexible arm for holding the tray containing the artificial hair and light-curing glue near the patient's eyelashes during treatment. [Effects of the Invention]

[0014] The eyelash extension system of the present invention is configured to harden the glue by emitting light from the tip of the tweezers. This allows light to be irradiated from an extremely close distance (1-3 mm) to the glue while the adjacent eyelashes are removed using the tweezers. Therefore, light can be applied only to the adhesive portion of the eyelashes while maintaining strong hardness, and there is no need to switch to a separately configured irradiation device from the tweezers and bring it closer to the patient's face. As a result, the procedure time for eyelash extensions can be dramatically reduced.

[0015] The present invention, when configured to emit light in a direction substantially perpendicular to the long axis of the elongated member and towards the inside of the tweezers body, allows the glue to harden without directly shining light on the patient lying on their back, unlike when light is shone from above towards the patient's face or eyes, thus protecting the patient's skin and eyes.

[0016] Furthermore, by configuring the light source to automatically flash at a predetermined cycle, the glue irradiated by the flashing light hardens gradually, forming layers and improving adhesive strength. Additionally, by setting the light to automatically turn off during the periodic intervals when the technician picks up a new artificial lash, applies glue, and blends it with the natural lash, the technician no longer needs to manually turn the light on and off, reducing their workload and eliminating the physical instability associated with switch operation, allowing for more accurate and reliable treatment.

[0017] Further, since glue may adhere to the tip of the tweezers and cure during the procedure, configuring the tip of the tweezers to be replaceable or providing a transparent cover on the light emission port to prevent the optical path from being blocked can extend the service life of the instrument.

[0018] In addition, when the light irradiation intensity can be switched in at least two levels, it is possible to realize a usage method in which weak light is irradiated first to gradually cure the artificial hair while finely adjusting the direction and length of the artificial hair, and finally strong light is irradiated to completely cure the artificial hair. Furthermore, when the tweezers and the power supply are configured separately and connected by wiring, the instrument held in the hand for the procedure is lighter than incorporating a power supply therein, which can improve operability.

[0019] Furthermore, when a detachable light shield (for example, a UV-cut transparent acrylic plate) for protecting the practitioner's eyes is provided on the tweezers, the practitioner's eyes can be protected while ensuring visibility. Furthermore, by providing a movable arm for holding a tray, the tray carrying artificial hair and photocurable glue can be held in the immediate vicinity of the eyelashes, and the range of movement of the practitioner's hands can be minimized to improve efficiency.

[0021] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Fig. 1 is a diagram showing the configuration of forceps 30 according to an embodiment of the eyelash extension system of the present invention. As shown in this drawing, the forceps 30 of the present invention is formed by connecting the root sides of two elongated members 31a and 31b, wherein the tips are separated when no force is applied, and the tips can be brought close to each other or closed when a force is applied. Each of the elongated members 31a and 31b incorporates an LED light source on the root side (not shown). Light emission ports 32a and 32b are respectively provided at the tip portion of the elongated member 31, more specifically, a position several mm closer to the root side than the pointed tip and at mutually opposing inner portions of the forceps 30, and are configured such that light from the LED light sources is emitted from these ports in directions D1 and D2 substantially toward each other.

[0022] The LED light source used in the eyelash extension system of the present invention can be appropriately selected according to the photo-curable glue to be used, and it is preferable that the LED light source has little influence on the human body. For example, an LED that emits ultraviolet light or visible light having a peak wavelength of any one of 365 to 410 nm, preferably 400 nm, can be used. Unlike thermosetting or room temperature curable resins, the photo-curable glue is a photo-curable resin that cures by the action of light energy, and is composed of a monomer, an oligomer, a photopolymerization initiator, and other components such as a thickener, a stabilizer and a pigment. By matching the peak wavelength of the LED light source with the wavelength at which the polymerization initiator of the photo-curable resin is activated, the photo-curable resin can be efficiently cured. Photo-curable resins and light sources used therefor are known in the art, and for example, details are also described in the above-mentioned prior art documents, so further detailed description in the present specification is omitted.

[0023] As shown in Figure 1, the light from the LED light source is configured to be emitted in a direction approximately perpendicular to the long axes of the elongated members 31a and 31b, and toward the inside of the tweezers 30 (directions D1 and D2). The optical path from the LED light source inside the elongated member 31 to the light emission port 32 may be hollow, but for example, the elongated member 31 may be made of a transparent acrylic material with an internal mirror coating (mirror spray) applied to its surface to create an optical path that utilizes internal reflection, or the light may be emitted from the LED light source through an optical fiber to the light emission port 32 with the directionality described above. The position of the LED light source in the elongated member 31 can be appropriately determined considering design factors such as weight balance, and if the optical path is hollow, mirrors, prisms, focusing lenses, etc. can be appropriately arranged to give directionality to the light. Furthermore, depending on the embodiment, a directional (i.e., not omnidirectional) LED light source may be directly attached to the inner surface of the tip of a conventional pair of tweezers, and the light may be irradiated from there in a desired direction. Furthermore, when using optical fibers, an LED light source can be placed on the power supply unit, which is separate from the tweezers 30, and the optical fiber can be extended from there to the tweezers 30. In yet another embodiment, the power supply unit may have a rechargeable battery built into the tweezers 30, and the tweezers 30 may be a standalone and rechargeable type.

[0024] In the embodiment shown in Figure 1, the wiring 16 of the LED light source is connected inside the tweezers 30 and extends outwards from the elongated member 31a on one side. Since the tweezers 30 in this embodiment are held in the hand and the tip is narrowed or loosened by applying force, the ON / OFF of the LED light source is configured to be operated by a foot switch (for example, the foot switch 58 in Figures 5 and 6). In this case, the LED light source may be configured to be ON while the foot is pressed down and OFF when released, or it may be configured to be ON for a predetermined period (for example, 5 seconds) when the foot switch is pressed once. Furthermore, as will be described later, it may be configured to blink repeatedly for a predetermined period when the foot switch is pressed once.

[0025] The tweezers 30 configured in this way can be used in much the same way as conventional left-handed tweezers. That is, as shown in Figure 2, hold the tweezers 5 in your dominant hand (right hand in this example) and the tweezers 30 according to the present invention in your non-dominant hand (left hand). Use the tweezers 5 to pick up one (or more) artificial hairs 15 and apply glue to the base. Use the tip of the tweezers 30 to move the eyelashes on either side of the target eyelash 20 to create working space, and then adhere the artificial hair 15 to the eyelash 20. At this time, if you rub the eyelash 20 several times with the base of the artificial hair 15 so that the glue is applied all around the eyelash 20, the overall strength after curing can be increased. While maintaining the state shown in Figure 7(b), that is, the state in which the artificial hair 15 is adhered to the eyelash 20, turn on the LED light source, and light will be irradiated from the light emitters 32a and 32b toward the eyelash 20, activating the polymerization initiator and curing the light-curing glue in a few seconds. By selecting the appropriate light source and corresponding glue, light-curing glue can be fully cured in just a few seconds (e.g., 2-5 seconds) without moving hands or switching instruments during the procedure. Therefore, the procedure is faster than when using conventional cyanoacrylate adhesives, and there is no need to work on one eye at a time alternately to allow sufficient curing time. In this example, after attaching 15 artificial hairs to one natural eyelash 20, the process moves on to attaching a new artificial hair to the adjacent eyelash.

[0026] As shown in Figures 1 and 2, the light used to cure the light-curing glue is directed inward from a distance of a few eyelashes from the target area and is oriented so as not to be directed towards the patient's eyes. This avoids adverse effects such as strong ultraviolet light being directed towards the patient's eyes or skin. If necessary, the light-emitting port 32 of the tweezers 30 may have a canopy-like projection that physically blocks downward-directed light during use. Alternatively or additionally, a focusing lens may be provided at the light-emitting port 32 to further restrict the light to a desired direction.

[0027] In this embodiment, the LED light source is switched ON / OFF using a foot-operated foot switch (for example, foot switch 58 in Figures 5 and 6), but in another embodiment, a switch may be provided on the tweezers 30 itself (for example, on the side of the elongated member 31). Also, instead of a configuration where the LED is ON while the switch is pressed and OFF when released, the LED may be configured to switch ON / OFF each time the switch is pressed.

[0028] In yet another embodiment, the system may be configured such that when the foot switch 58 or another switch is turned ON, the LED light source of the tweezers 30 automatically blinks in a predetermined cycle. In this case, when the switch is turned OFF, the blinking may stop and the light may turn off completely, or the light may blink repeatedly for a predetermined period after the switch is turned ON before turning off completely. The blinking cycle can be, for example, alternating between on and off for 0.5 seconds each, alternating between 3 seconds on and 2 seconds off, or blinking for 0.4 seconds, 0.6 seconds, and 0.8 seconds, with 0.5 seconds off in between each of these on periods. The blinking cycle may be fixed at the time of factory shipment, or the on and off times may be arbitrarily set using an operation panel (not shown) provided in the system. By providing periodic off periods in the glue curing cycle, the glue can be cured slowly while blending in, a layer can be formed in the curing glue to increase its strength, and the glue can be prevented from clumping. Furthermore, in an embodiment where the light is turned on for 3 seconds and then off for 2 seconds, for example, a new artificial eyelash can be prepared during the off period and placed on the natural eyelash, and then cured during the on period. With this configuration, the practitioner does not need to operate the light ON / OFF for each eyelash, reducing the burden on the practitioner, and the shaking caused by switching the switch is eliminated, resulting in more stable hands.

[0029] The tweezers of this embodiment can be modified in various ways, as described below. (1) An example in which light is shone from only one side of the tweezers. In the embodiments shown in Figures 1 and 2, light is emitted from both ends of the tweezers toward each other. However, the LED light source and light path may be provided only on one of the elongated members 31, and these functions may be omitted from the other elongated member. Even in this case, the glue can be cured by shining light from a close distance while ensuring space by clearing the eyelashes on both sides of the target eyelash. In this embodiment, a reflective structure (mirror or reflective coating) may be provided on the part of the elongated member opposite to the light-emitting part that is illuminated, and this reflection may be used to illuminate the entire circumference of the eyelash.

[0030] (2) An example in which the illumination intensity of the LED light source can be switched. For example, the foot switch that operates the LED light source can be equipped with two switches, one for low and one for low intensity. This allows for gradual hardening of the artificial hair by first irradiating it with a weak light to allow for fine adjustment of its direction and length, and then irradiating it with a strong light at the end to completely harden it. Alternatively, the foot switch can remain as a single unit, and an electronic control circuit (not shown) can be incorporated into the power supply unit to configure it so that when the foot switch is pressed, a weak light is emitted for the first predetermined number of seconds, and then a strong light is emitted for the following predetermined number of seconds. In this case as well, the irradiation may be configured to stop immediately when the foot is removed from the foot switch. In a further modification, the two elongated members 31a and 31b that make up the tweezers 30 may be configured so that a strong light is emitted from one and a weak light is emitted from the other, and the two can be switched to emit light. In this case, there are four operational settings: both OFF, one ON, one ON, and both ON.

[0031] (3) An example in which the wavelengths of the left and right LED light sources are different. For example, if one elongated member 31a is equipped with an LED light source having a peak wavelength for curing photocurable glue, and the other elongated member 31b is equipped with an LED light source that emits ultraviolet light with a bactericidal wavelength (200-300 nm, preferably around 222 nm), the procedure can be performed while sterilizing the artificial hair, glue, and even the treatment area.

[0032] (4) Example using a replaceable quartz prism at the tip of the tweezers Figure 3 is a perspective view showing an embodiment in which a replaceable quartz prism is used at the tip of the tweezers. As shown in Figure 3(a), the tweezers 35 according to this embodiment comprises flexible elongated members 36a and 36b, and quartz prisms 37a and 37b inserted axially into the tip of the elongated member 36. The tips of the quartz prisms 37a and 37b are cut at an angle, allowing incident light from the base end to be reflected at 90° and emitted in the direction of the inside of the tweezers. Optical fibers 38a and 38b are introduced to the base ends of the elongated members 36a and 36b, respectively, allowing light to be incident on the base ends of the quartz prisms 37a and 37b through almost the entire length of the elongated member 36. The optical fiber 38 is connected to a light source provided in the main unit 57 shown in Figure 5, for example. Appropriate coatings or paints can be applied to the bevels and roof faces of the quartz prism 37. With this configuration, the incident light from the optical fiber 38 can be directed towards the desired target direction, and if the glue hardens due to long-term use, only the quartz prism 37 at the tip can be replaced.

[0033] Furthermore, as shown in Figure 3(b), the tweezers 35 of this embodiment can be separated into a pair of elongated members 36a and 36b and used individually or separately. As shown in Figure 3(b), two engaging recesses 39 are provided at the inner base end of one elongated member 36a, and these engage with corresponding engaging protrusions (not shown) provided at the base end of the other elongated member 36b, allowing the two to be detachably connected. With this configuration, the elongated members 36 can be separated and used individually, or, for example, when two or more people are performing the procedure, one person can hold one elongated member 36a and one 36b in each hand. In this embodiment as well, an LED light source may be incorporated into the elongated members without using optical fibers as described above.

[0034] (5) Embodiments equipped with a light shield for the practitioner Figure 4 shows an embodiment of an eyelash extension system equipped with a light shield for the practitioner. As shown in Figure 4(a), the system comprises tweezers 40 and a detachable light shield 45. The tweezers 40 are an improved version of conventional metal tweezers, with holes 41 drilled in the tips of the elongated members 40a and 40b on both sides, and optical fibers 42 fixed there toward the inside (facing each other). The optical fibers 42 are routed along the side or inside of the elongated members 40a and 40b so as not to interfere with operation, and are fixed to the handle end of the tweezers 40, extending from the handle end of the tweezers 40 to a power supply unit equipped with an LED light source (for example, the main unit 57 shown in Figures 5 and 6). The optical fibers 42 are flexible and do not hinder the fine movements of the tweezers 40. A foot switch extends from the power supply unit (for example, the foot switch 58 in Figures 5 and 6), allowing the practitioner to control the ON / OFF of the LED light source with their foot.

[0035] On the other hand, the light shield 45 consists of a detachable part 47 made of elastic resin for detachable attachment to the tweezers 40, and a UV-cut plate 48 made of transparent acrylic. The UV-cut plate 48 is configured to absorb light of the wavelength of the LED light source used in this system. As shown in Figure 4(b), it is attached to an appropriate location on the tweezers 40 to prevent the light from the optical fiber 42 from directly reaching the practitioner's eyes during use. The shape of the detachable part 47 and the UV-cut plate 48 can be appropriately changed depending on the shape of the tweezers to which they are applied.

[0036] Figure 5 is a schematic diagram showing the entire system according to a further embodiment of the eyelash extension system of the present invention. The eyelash extension system 50 shown in this figure comprises tweezers 55, a movable tray 56, a main unit 57, and a foot switch 58. The main unit 57 incorporates a power supply unit and an LED light source unit (not shown) and has sufficient weight to stably support an upward-extending support column 57a. One end of a flexible arm 59, which can freely change the position of the movable tray 56, is fixed to the support column 57a. The flexible arm 59 is configured to displace the movable tray 56 when force is applied, but to remain in its position when the hand is released. Since this structure itself is publicly known, a detailed explanation is omitted in this document. Bundles of artificial hairs to be attached and light-curing glue are placed on this movable tray 56.

[0037] The system 50 may further include an electric reclining seat 60 commonly used in barbering or dental clinics, as shown in Figure 6. During the procedure, the patient is seated in the reclining seat 60 and reclined to an angle that is easy for the practitioner to work with, and the tray 56 is positioned in an easily accessible location very close to the eyelashes. During the procedure, when the foot switch 58 is pressed with the foot, LED light is emitted from a light emitter (not shown) at the tip of the tweezers 55. The tweezers 55 may have the same configuration as the tweezers in any of the embodiments described herein, or a combination of multiple configurations.

[0038] Using this system, a tray 56 containing artificial hair and light-curing glue is placed at the desired position near the eyelashes. The technician uses tweezers (conventional type, not shown) in their dominant hand to pick up the artificial hair and apply glue. They then use tweezers 55 in their other hand to remove the eyelashes on either side of the target eyelash to create space, and then adhere the artificial hair to the eyelash. At this point, the adhesion site between the target eyelash and the artificial hair is still located inside the tip of the tweezers 55 (between the two elongated parts). When the technician presses the foot switch 58 with their foot, light is shone onto the adhesion site from a close distance of 1-3 mm, and the glue hardens in a few seconds. By repeating this process, eyelash extensions can be performed much faster than before.

[0039] Although several embodiments of the eyelash extension system of the present invention and several examples thereof have been described in detail, the present invention is not limited to the embodiments illustrated and described above, and can be realized in various modified forms.
