Description

  The method and apparatus generally relate to the field of skin treatment and more particularly to epilation.

  Actually the appearance is important for everyone. In recent years, methods and devices for different cosmetic and dermatological treatments have been developed. Among these are hair loss, vascular lesion treatment, wrinkle removal, skin rejuvenation and the like. In these treatments, the skin surface is irradiated at a temperature high enough to achieve the desired effect to heat deep skin or tissue volumes. This is typically in the range of 38-60 ° C. The effect is to weaken the hair shaft or destroy even the hair follicle or hair root.

  Another desired effect is hair growth delay. This is typically accomplished by irradiating the initially depigmented skin surface with a laser, LED, xenon lamp, ultra-short pulsed light (Intense Pulsed Light (IPL)), or incandescent lamp radiation. These are commonly referred to as light emission. The light radiation has a single wavelength, for example a laser, or has several wavelengths or a broad spectrum. Such wavelengths are selected to be optimal for the color of the contrasted element of the skin segment undergoing treatment and are typically in the range of 400 to 1800 nm. Light radiation, usually flash light or pulsed light, is applied to the skin with the aid of an applicator having a predetermined size aperture. In order to “cover” the entire skin surface, the aperture is removed in some places in a relatively accurate manner based on steps equal to at least one aperture dimension so that there is no area on the skin that is to be treated twice. Need to move to. To avoid this, the individual visually tracks the applicator position. Light pulses inevitably reach his / her eyes, disturbing the individual and affecting the applicator position tracking and hair removal process. Such a device achieves the desired effect only when a predetermined energy density is applied to the skin tissue. If the device moves too fast or too slowly across the skin, the device becomes ineffective or causes burns.

  Methods have been developed to treat deep layers of skin or tissue based on applying several radio frequency (RF) to the skin simultaneously. In such a method, electrodes are applied to the skin, and RF voltage is applied between the electrodes in a pulsed or continuous waveform (CW). The characteristics of the RF voltage are selected to generate an RF induced current in a predetermined volume or layer of tissue undergoing treatment. The current heats the tissue to the required temperature. This is typically in the range of 38-60 ° C. The temperature destroys or damages the hair follicle or hair root and delays further hair growth.

  There are devices that combine light and RF treatments. Such devices are typically configured to illuminate a defined segment of the target skin that is substantially similar or equal to the aperture surface. Light radiation is directed to the skin segment through the aperture. Typically, electrodes are placed near the periphery of the aperture. Typically, tissue layers deeper than RF is heated by light are heated. This destroys / damages the hair bulb and / or hair follicle. There is a delicate relationship between the amount of RF energy and the amount of light radiation applied to the same skin segment. Excessive light between both causes skin burns, while applications that are less than the optimum ratio of RF energy to light radiation do not provide the desired treatment results.

  There is a need in the market for a device that operates by allowing the user to: i) Avoid skin burns or poor skin treatment results. ii) Avoid looking at the area receiving treatment for a long time throughout the treatment.

  In the following detailed description, reference is made to the accompanying drawings that form a part hereof. This reference is illustrated by the illustration of different embodiments in which the present apparatus and method may be implemented. Since elements according to embodiments of the apparatus can be in several different orientations, the directional terms are for illustrative purposes and are not limiting in any way. It should be noted that other embodiments may be used and structural or logical changes may be made without departing from the scope of the method and apparatus. The following detailed description is, therefore, not to be taken in a limiting sense. The scope of the apparatus and method is defined by the appended claims.

  As used herein, the term “skin treatment” refers to hair removal and treatment, skin rejuvenation treatment, wrinkle removal, and collagen contraction or destruction of various skin layers such as stratum corneum, dermis, epidermis. Such treatment is included.

  The term “skin surface” refers to the outermost skin layer. This may be the stratum corneum.

  Reference is made to FIG. 1, which is a schematic diagram illustrating one embodiment of a personal skin treatment device. The apparatus 100 includes an applicator or device 104 configured to slide over the subject skin, a base 108 including a charge storage mechanism such as a controller, a power supply module, and a capacitor (not shown), and an applicator 104. And a supply cord 112 connecting between the bases 108. The power supply includes a transformer with or without a rectifier. The device 100 is powered from a standard power network outlet or from a rechargeable or conventional battery. The applicator or device 104 is designed to easily hold the body (shown as having a transparent envelope). The body includes an infrastructure structure 116, a cooling means such as an axial fan or blower 120, a control circuit 124 that controls the operation of the apparatus 100, and a hair removal attached to the infrastructure structure 116 or assembled on a common frame. Mechanism 128. The epilation mechanism or head 128 may be one of a shaver head, a head such as a stripping or tweezer epilator, or a razor. The head 128 is a removable head. For safety reasons, the electrical contact of the head 128 is configured so that the epilation mechanism is powered on only when inserted in the proper position. In one additional embodiment, the epilation mechanism may be replaced by a skin rejuvenation head (FIG. 8).

  At least one visible status indicator 132 is attached to the device 104, such as an LED that notifies or displays to the user operational status of the device and / or skin treatment process parameters. At least one optional audible operational status indicator 136, such as a buzzer that signals the status of skin treatment process parameters to the user, is attached to the device 104 or disposed on the base.

  FIG. 2 is a schematic diagram illustrating one embodiment of an applicator or device infrastructure assembly for personal skin treatment. Provided in the infrastructure structure 116 is a light radiation application module 200, a mechanism or configuration for continuously moving the device 104 across the skin shown in FIGS. 5A-5C, a moving speed monitoring mechanism (FIG. 5A), an infrastructure structure frame 116 (FIG. 1) is a safety switch (FIG. 3) provided at 116 (FIG. 1) and activated by the radiation providing module 200 (FIG. 2). The epilation mechanism 128 is configured to attach to the infrastructure frame 116 and is configured to be capable of undergoing a treatment or mechanical epilation from a target skin segment. Optionally, a pair of electrodes 220 are attached to the infrastructure frame 116.

  FIG. 3 is a schematic diagram illustrating one embodiment of an infrastructure frame 116 assembly, shown without the epilation mechanism 128 (FIG. 1). Shown are a safety switch 300 attached to the infrastructure frame 116 and a sensor 528 for the direction of movement of the device 104 shown in FIG. 5A. The safety switch 300 is activated by inserting the radiation application module 200 (FIG. 2) into the frame 116 at that position. Thereby, useless or erroneous operation of the module 200 can be avoided. For example, a high voltage is not present and “live” at the electrode of the applicator 104. Thus, no one is at risk of high voltage when the disposable cartridge is removed.

  According to some embodiments of the present disclosure, an RFID device is connected to the control circuit 124 (FIG. 1). The RFID device needs to be preloaded with the maximum number of pulses to be emitted before the radiation imparting module 200 needs to be replaced, and the count needs to be reduced for each emitted pulse. Alternatively, the RFID device is preloaded with all the energy applied to the skin in one treatment before the radiation application module 200 (FIG. 2) needs to be replaced. The RFID device also functions as an additional safety measure. If the RFID cannot be identified, i.e., if the radiation application module 200 is not correctly installed, the control circuit 124 prevents the radiation application module 200 from emitting a pulse.

  One additional example is a 1024-bit 1-Wire® EEPROM, such as DS2431, commercially available from Maxim / Dallas Semiconductors of Sunnyvale, CA 94086, USA. A 1-Wire EEPROM that acts as a counter can be assembled on the control print circuit 124 that controls the radiation application module 200, among others. Similar to RFID, desired information may be preloaded on the counter. The same 1-Wire EEPROM can function for the purpose of identifying the reliability of the radiation grant module 200.

  FIG. 4 is a schematic view showing an embodiment of the reflector of the light emission providing module and a cooling method thereof. The module 200 is implemented as a disposable cartridge that includes a light radiation source 400, a reflector 404, and a dielectric coated protective window 408. The reflector 404 is configured to reflect the emitted light radiation to the skin segment undergoing treatment. Window 408 defines an aperture. Through the aperture, light radiation is emitted to the skin. The light source 400, shown in broken lines, is an incandescent lamp, such as an AGAC 4627 high power density xenon flash lamp commercially available from PerkinElmer Optoelectronics, Inc. 65199 Wiesbaden, Wenzel-Jaksch St. 31, Germany, or an LED, laser It may be any one of a group of diodes, solid state lasers, gas lasers, xenon IPL (Intense Pulsed Light) lamps.

  The reflector 404 is a prism case or prism body having a flat facet and a polygonal cross section. Alternatively, it is a tubular case or tubular body having an optional curvature of 2 or more. It may be a simple cylindrical cross section, a parabolic cross section, or any other cross section where the light radiation can be uniformly concentrated and distributed across the aperture of the window 408. The light radiation is emitted to the skin through the aperture of window 408. The dielectric coating of window 408 is selected to transmit the relevant section of the light emission spectrum to the skin segment undergoing treatment and reflect the other sections. The reflector 404 has a plurality of openings 412 that allow air to pass inside the reflector. The opening 412 is disposed near the top of the reflector 404. A dielectric cover protection window 408 disposed near or attached to the open longitudinal portion of the reflector 404 forms an air conduction channel 420 with the reflector 404. Air conduction channel 420 is bounded by reflector 404 on one side and window 408 on the other side. A portion of the flow of cooling air 424 generated by a cooling element such as axial fan 120 (FIG. 1) enters channel 420 through opening 412. This is directed into the air conduction channel 420 along the light source 400, shown in broken lines, to cool the light source 400. The butt end opening 428 of the reflector 404 terminates the air conduction channel at both ends and functions as a cooling air outlet. The area of the butt opening or exhaust 428 is at least equal to or greater than the area of the opening 412 that allows air to pass through the reflector 404 and through the air conduction channel 420. The other part of the cooling air flow 424 flows around the outer section of the reflector 404 and cools that outer section of the reflector 404.

  As shown schematically in FIG. 10, according to some embodiments of the present disclosure, the cooling means includes a rotary blower 1000. The blower 1000 blows air indicated by an arrow 1010 into one side of the light emission providing module 200 (FIG. 2). The air flows parallel (along) the light radiation source 400 and the reflector 404 (FIG. 4) and emerges from the opposite side of the light radiation application module 200 as indicated by arrow 1020.

  Again, as schematically shown in FIG. 10, according to some embodiments of the present disclosure, a second glass window 1030 is placed parallel to the window 408. A portion of the cooling air marked with an arrow 1040 blown by the blower 1000 flows between the two windows 408 and 1030. As shown in FIG. 11, an inclined lamp electrode 1100 is installed on the air intake side of the light radiation source 400 to promote air flow toward the window. Arrows 1130 schematically illustrate the cooling air flow that flows inside and outside reflector 404 and between windows 408 and 1030. The reflector 404 is shown in FIG. 11 as a prism structure.

  According to some embodiments of the present disclosure, the fan 120 shown in FIG. 1 may be used to cool the air between two glass windows. It has been experimentally proven that three or more windows parallel to the window 408 have a cooling air flow between them to provide good thermal insulation and that the temperature of the part of the device in contact with the skin hardly changes. Yes.

  According to some embodiments of the present disclosure, a thermal sensor 1050, such as a thermistor, or any other type of temperature measuring means may be used as a safety measure against overheating if the cooling means is malfunctioning. It is installed at either the inflow end or the outflow end of air.

  Windows 408 and 1030 are made from Pyrex, sapphire, quartz, or specially processed borosilicate glass. Window 1030 or both windows are coated with a dielectric coating. The dielectric coating functions as a filter that reflects unwanted wavelengths, such as UV and predetermined IR wavelengths emitted from the light source 400.

  As also shown in FIG. 11, according to some embodiments of the present disclosure, two reflectors (1110, 1120) are provided on both sides of the two windows (1030, 408). This prevents light scattering outside the treatment area.

  The architecture of the light radiation application module 200 and the method of cooling it allows a compact and efficient light radiation source to be produced, providing sufficient output for skin treatment. Module 200 operates in a pulsed or continuous mode of operation. It has been found that low repetition rates of light emission or light pulses are bothersome for users who always track the applicator position visually. In order to relieve the user's sensation, the light source emits several low power light pulses intervening between high power treatment pulses. As a result, the repetition period of the light pulse is increased, and the annoying and disturbing effects of the light pulse having a low repetition period are reduced.

FIG. 5A is a schematic diagram illustrating one embodiment of a device movement mechanism. This is a bottom view of an exemplary mechanism for moving device 104 continuously across the skin. The mechanism includes a DC motor 500 of appropriate size and output. DC motor 500 is coupled to one or more drive wheels 508 or one of the caterpillar by one or more gears 504 (registered trademark) type track (caterpillar type track). The user attaches device 104 to skin 512 (FIG. 5B) and applies minimal force so that the device does not fall off the skin. Device 104 may have any suitable amount of additional auxiliary wheels 516 as required. The operation of the DC motor 500 allows the device 104 to move across the skin 512 at a variable speed. A wheel or roller 528 of known diameter is in contact with the skin. The roller 528 rotates according to the movement of the device. By measuring the rotational speed of roller 528, the device movement speed can be determined in a manner well known to those skilled in the art. Alternatively, the diameter of one of the plurality of wheels 508 or 516 may be known.

  In another embodiment of the device movement mechanism shown in FIG. 5B, a peristaltic piezoceramic motor 516 implemented as a caterpillar type track moves the device 104 across the skin 512 as indicated by the arrow 540. In a further additional embodiment of the device movement mechanism shown in FIG. 5C, a belt 520 driven by a piezoceramic motor 524 or other type of motor moves the device 104 across the skin 512 as indicated by arrow 544.

  The device movement mechanism described above allows the device 104 to move at a variable speed to accommodate different skin treatment conditions. However, this requires the ability to detect or monitor and correct device movement speed. FIG. 6 is a schematic diagram showing an embodiment of a device moving speed and moving direction detection configuration. In device 104 (FIGS. 1 and 5) travel speed monitoring configuration 600, a rotating wheel 602 or roller of known diameter makes permanent contact with skin 512. The wheel 602 has an O-ring 604 that is tensioned around the wheel 602. The travel speed monitoring configuration 600 is implemented as a wheel 602 -I having an opening 606 (FIG. 6B). The wheel 602 -I is disposed between the LED 608 and the detector 612 and is configured to generate a pulse when the opening passes between them. Alternatively, the wheel may be connected to a speed measuring device such as a tachometer that communicates with the control circuit 124, for example. In response to the speed reading, the control circuit 124 (FIG. 1) changes the moving speed of the device 104. In an alternative embodiment, a configuration similar to an optical mouse monitors device 104 travel speed.

  Continuous detection of device movement speed and direction of travel, combined with visual or audible signals that inform the user of treatment status, frees the user from the cumbersome task of constantly tracking the applicator position. The user nevertheless needs to ensure that the applicator travel speed is in accordance with a desired applicator speed corresponding at least to the source pulse repetition period. The source pulse repetition period establishes the light radiation output and the active size of the aperture. Visible signal indicators and audible signal indicators provide the user with the information necessary for decisions regarding skin treatment conditions. The user may not remember the location of the strip or strips that have previously undergone treatment.

  The direction movement sensor is a wheel 528 (FIG. 5) having an asymmetric aperture 614, a detector 612, and an LED 608. Detector 612 and LED 608 are configured to generate a pulse when the aperture passes between them. Alternatively, one of the wheels 508 or 516 may have an asymmetric opening. Depending on the direction of travel, the pulses caused by the modulation of LED radiation by the aperture 612 have different rise times. This indicates the direction of movement. When the skin segment treatment is complete, the operator changes the direction of travel of the applicator.

  FIG. 7 is a schematic diagram illustrating one embodiment of an electrode for a personal hair removal device. Skin treatment device 104 optionally includes a pair of removable electrodes 220 (FIG. 2). The electrode 220 is configured to be operable to apply RF energy to the skin segment. The RF electrode 220 has an elongated body configured along at least one side of a protective window or aperture 408 (FIG. 4). The RF electrode 220 is floated on the spring 700 with respect to the infrastructure frame 116. Alternatively, the electrode 220 may include a solid metal strip 710 attached to the exterior side of the housing of the light delivery module 200. A metallization appropriately deposited on the surface of module 200, which may be plastic, can also function as electrode 200. During the skin treatment, the RF electrode 220 is in firm contact with the skin and accurately follows the surface morphology of the skin. The RF electrode 220 or 710 may have a bare metal surface for conductive coupling with the skin. Alternatively, it may be a dielectric coated electrode and may be capacitively coupled to the skin.

  FIG. 8 is a schematic diagram illustrating an exemplary disposable and replaceable skin rejuvenation device for use with the apparatus. Device 800 is provided in place of the epilation mechanism 128. Device 800 is a cylindrical or other three-dimensional shaped carrier 802. On the surface of the carrier 802 is a dome-shaped conductive element 804. The conductive element 804 is configured such that the dome 804 protrudes from the outer surface of the carrier 802. The carrier 802 is manufactured by stretching a flexible substrate on a carcass. This may be a solid cylinder or a cage structure. The side 816 of the carrier 802 bears the contact strip 820. RF voltage may be supplied to the dome 804 through the contact strip 820. Such a carrier configuration allows the carrier to be applied and translated over a relatively large skin segment. In the context of this disclosure, “large skin segment” means the dimension of a skin segment that exceeds the dimensions around the carrier surface or contact electrode carrier surface. Carrier 802 is rotationally symmetric and rolls on the skin to obtain a reasonable thermal relaxation time for the first treated skin segment and easily reposition to provide treatment for adjacent skin segments. Can do. It is also possible to return to the same skin segment that was previously treated. Carrier repositioning does not leave untreated skin segments or skin patches. Then, the remaining patchwork type skin pattern is eliminated. This type of skin treatment is actually a continuous skin surface treatment process. The carrier 802 may be a reusable or disposable part.

  FIG. 9 is a schematic diagram illustrating one embodiment of a skin treatment method using the present device and apparatus. For skin treatment, the device 104 is applied to a skin segment 900 that undergoes the treatment. A firm or at least almost firm contact is possible between the RF electrode 220 (FIG. 2) and the skin. When the light delivery module 200 is activated, a mechanism that continuously moves the device across the skin moves the device in the desired direction, for example, along the skin segment undergoing treatment. In one embodiment, light radiation is directed through the aperture 408 to irradiate the skin segment undergoing treatment with a constant light radiation output. The light radiation is supplied in continuous or pulsed mode. A travel speed monitoring configuration 600 (FIG. 6) sets the appropriate travel speed. The dependency between the moving speed and the light radiation output is prepared as a look-up table (LUT) and loaded into the control circuit 124. As the treatment progresses and the device 104 advances across the skin, the device 104 reaches the boundary of the skin segment undergoing the treatment. When device 104 reaches the end of a skin segment that has undergone a treatment or shaving, the user manually repositions device 104 on the next skin segment to receive treatment or on a skin segment that has not received treatment, and the same Or set to move in the opposite direction. The risk of causing skin burns by reducing the treatment to the same skin segment twice is reduced. This is because there is time for skin cooling between successive skin segments by the device 104. Light radiation delays future hair growth on the treated skin segment by heating the hair follicle. RF energy applied to the same skin segment heats the deep skin layer where the hair bulbs and hair follicles are present. The heat generated by the RF energy destroys them, enhancing the hair removal process performed by light radiation.

  In an additional embodiment of the skin treatment method using the device and the apparatus, the user applies the skin treatment device 104 to the skin segment to be removed. The skin segment is removed by mechanical means such as shaving or stripping. Following mechanical hair removal, light radiation of the appropriate power and wavelength is applied to the same skin segment that received the treatment. Optionally, RF energy may be applied to the same skin segment. The application of light radiation and RF energy further delays hair growth and removes residual hair remaining after mechanical hair removal from the treated skin segment. Similar to the first disclosed method, the device that provides treatment to the skin segment itself automatically moves from the treated skin segment to the other untreated skin segment.

  Several examples have been described. Nevertheless, various modifications are possible without departing from the spirit and scope of the method. Accordingly, other embodiments are within the scope of the following claims.
