The technical FIELD TO WHICH the INVENTION RELATES.

The present invention relates generally to the removal, i.e. the (temporary or permanent) hair removal with light.

The prior art INVENTIONS

Photoepilation is in itself known; see, for example, U.S. patent 5735844. Light from a suitable light source (laser, flash lamp) is absorbed by the melanin of the hair and/or follicle. The absorbed light is converted into heat. This heat damages or even destroys the follicle. Hair falls out, and the growth of new hair is delayed or even completely prevented.

Light usually fail pulses. There are several parameters that affect the efficiency of the epilation: pulse duration, pulse frequency, wavelength or spectral band of light and the flux density (or energy density, expressed in j/cm2). When planned permanent hair removal and, consequently, the destruction of the follicle in the literature reported high densities of flow up to 60 j/cm2supplied with pulses in the range from several milliseconds to several hundred milliseconds. In U.S. patent 7044959 method of temporary inhibition of hair growth using parameter settings in a wide range for pulsed sources, and for continuous sources with scanning pen is the displacement. In the article "Low dose epilation by alexandrite laser: a dose response study", Med.Laser Appl., volume 16, 2001, pp. 293-298, M.: Drosner, and others, describes the research hair removal with the use of relatively low alexandrite laser. Wavelength is 890 nm, the flux density is from 5 to 10 j/cm2the pulse duration is 7 MS. The authors of the above article observed long-term hair removal, but have doubts about the stability of the proposed method.

The INVENTION

Professional systems typically are designed to summarize the high density of the flow, to achieve permanent hair removal. However, the problem is that there are different skin types. If the flux density is too low for the skin of some type, then the result may be unsatisfactory. If the flux density is too high for the skin of some type, the melanin in the epidermis will absorb too much light, and, therefore, probably a manifestation of undesirable effects, such as blistering and/or hyperpigmentation, and/or severe pain. Therefore, when working with these professional systems options must be installed by qualified professionals, to ensure that the settings are suitable for the corresponding type to the patient. In addition, the processing of high-density stream to be combined with the cooling of the skin to ease pain and prevent damage to the skin of the patient. Mentioned professional systems are bulky, heavy and expensive. Therefore, these systems are not suitable for the consumer market.

In another solution, aimed at reducing the overall dimensions of the device, a high flux density provide a reduction of the treatment area, i.e. the area of the skin that can be treated. In commercially available device for photoepilation, intended for the consumer market, the flux density reaches 18 j/cm2when the processing window only 0.8 cm2. The data clearly make the processing of large areas of skin, such as the leg, in an awkward, slow and tedious work.

The aim of the present invention is to provide a device for photoepilation, which allow convenient use by consumers in a home environment, with little risk or no risk of side effects and with little risk or no risk of unacceptably high levels of pain.

An additional objective of the present invention is a device for hair removal treatment that can be used by consumers with all types of skin, without the need for a qualified who tirovannyh specialists to work with the device.

Another objective of the present invention is a device for photoepilation, which has relatively small dimensions. In particular, the present invention should, with the said order, to provide portable and portable device for photoepilation.

In accordance with an important aspect of the present invention, depending on skin type choose the setting to a small flux density, which, however, is effective. This selection retains a low level of heat generation and, therefore, can be effectively cooled by a simple fan blowing outside air with a low flow rate, and, ultimately, makes it possible to reduce the size of the device.

The device in accordance with the present invention has features in claim 1 of the claims. Further advantages and preferred characteristics formulated in the dependent claims.

It should be noted that some known systems include a base unit and a portable unit. The device in accordance with the present invention is characterized by the absence of the base unit and the connection between the base unit and the portable unit, as the lamp and the controller are contained in a portable package. Thus, the device in accordance with this is Subramaniam is fully Autonomous.

BRIEF DESCRIPTION of DRAWINGS

These and other aspects, features and advantages of the present invention are explained hereinafter in the following description, at least one preferred variant implementation, with reference to the drawing, in which identical positions indicate the same or similar parts and in which:

1 schematically depicts a portable device for hair removal treatment in accordance with the present invention.

DESCRIPTION of embodiments

1 schematically depicts a portable device 1 for hair removal treatment in accordance with the present invention. The device includes a housing 10, the size of which is comparable to the size of the device for shaving. The housing 10 accommodates at least one intensive broadband source 20 of the light. The source 20 of the light, hereinafter referred to as "lamp", implemented respectively in the form of a xenon flash lamp, but can also be used in lamps of other types, provided that they provide the optical spectrum, which is suitable for the implementation of photoepilation. Because of the xenon flash lamp currently known, further explanation is not required.

The housing 10 is essentially closed, but it has one window 11 (however, the housing can also contain a lot of Windows), so that the light generated by the lamp 20, could go out to the Busa. The edge of the window 11 are called on the socket 12 of the device 1. The preferred form of the window is essentially rectangular, and the preferred amount is about 30 mm about 10 mm, However, for treating small areas of the skin, it may be desirable that the window had smaller dimensions, for example, approximately 15 mm 10 mm Box can be furnished with movable gates to reduce the outlet. Near the lamp 20 is opposite to the window 11 is the reflector 30 to increase the proportion of the generated light, which exits the housing, and to improve the efficiency of the outgoing light and reduce the amount of light unproductive lost inside. The reflector 30 may have, as shown, a suitable curvature to focus the outgoing light. It should be noted that the reflector 30 can be replaced with a system of multiple reflectors.

Xenon flash lamp capable of generating intense light in the spectral range from UV to infrared light, i.e., from less than 575 nm to 1700 nm. UV light can be dangerous. Therefore, ultraviolet light, it is advisable to filter. For this purpose, the filter 40 located between the lamp 20 and the window 11, choose to block UV light, and preferably are chosen to block wavelengths shorter than approximately 57 nm; thus the boundary of the above-mentioned range is not important. As suitable filters are essentially known, further explanation is not required. It should be noted that the designer can select a different filter with another characteristic that blocked the spectral range was a little bit different.

The range of wavelengths longer than approximately 1000-1200 nm, almost not involved or not involved in photoepilation. So you can also optionally enter a filter to block light with wavelengths longer than about 1200 nm, while the border is not important. However, in the context of the present invention the filtering is not required.

Near a window 11 inside the mirror system 35 determines the optical path for light passing from the filter 40 to the window 11 and, therefore, to be processed skin. These mirrors can be manufactured, for example, polished metal reflects light, which is not exactly to the window 11, and also to improve the efficiency of the outgoing light and reduce the amount of light unproductive lost inside.

The fan 50 to cool the lamp 20 is located inside the housing. This fan creates an air flow which passes along the lamp to cool it. The enclosure can contain output holes (not shown)to allow potatovodka out of the housing; mentioned output apertures can be placed near a window 11. The housing can also contain input holes (not shown)to allow air into the case.

The housing 10 accommodates the battery 60 for supplying power to the lamp 20 and the fan 50 is controlled by the electronic control device 70, usually containing a microcontroller or microprocessor, or similar device. The control device 70 includes input 76, a battery connected to the battery for receiving power from the battery. It should be noted that the battery 60 can be replaced with the discharge, but the battery may be rechargeable, and then the casing 10 is equipped with a connector (not shown) for connecting to the charger, usually made in the form of a network adapter. In an alternative embodiment, the battery can also be recharged by the scheme, receiving electromagnetic energy wirelessly and containing, with the aforementioned purpose, the take-up spool (not shown)located in the housing 10. As mentioned technology for battery charging, essentially known, further explanation in the present description is not required.

Control device 70 further comprises a tube output 72, which is connected to the lamp 20 to control the operation of the lamp. The controller 70 also contains the fan exit 75, which is connected to the fan 50 to control the operation of the fan.

The housing 10 provides a user control element 17 to turn on or off the device 1 for photoepilation. The control element 17 may be made in the form of a push-button switch, slide switch, etc. essentially known in the art. In the shown embodiment, the control device 70 further comprises an input 77 of a custom control, which is connected to the control element 17 and allows the control device 70 can decide to turn on the lamp and the actuation of the fan based on the position of the control element 17. In an alternative embodiment, the control element 17 may also be connected to the battery 60 to turn on and off battery power.

Suitable operating parameters depend on the skin type of the user. Therefore, the control device 70 is sensitive to user control element 14 connected to the user input 74, to install at least one working parameter. Usually there are six different skin types. Therefore, a suitable input element 14 is, for example, the rotary head for six positions to assign specific skin type.

It should be noted that alternatively, or in addition to the appointment of one of the six skin types item 14 enter the mod is et to allow some fine adjustment.

In addition, it should be noted that the input element 14 and the user control element 17 can be combined. For example, the input element 14 may have a seventh position, which is the off position.

Instead of hand-operated multi-position switch to be installed by the user, the device 1 may also include a sensor 90 skin type, which is mounted near a window 11 for receiving the reflected light that is reflected back by the skin, and is configured to generate a sensor signal type of skin colour or spectral distribution of the reflected light. In this case, the control device 70 includes an input 79 of the sensor skin, which is connected to the sensor 90 skin type.

The device may also contain the above-mentioned sensor 90 skin type in combination with the user input element 14. In this case, the sensor signal type of skin can lead, for example, to the General choice of the host device 70 of the six skin types, while the user input element 14 can be fine-tuned within the range set General skin type.

In principle, the lamp 20 can be enabled immediately when the user enables the button 17. However, this solution is not necessarily to prefer, since it is desirable that high-intensity light is generated only when required, i.e. when the astrub 12 is applied to the skin of the user. Therefore, the device 1 preferably contains at least one sensor 13 skin contact, which generates a signal contact, in contact with skin of the user. Control device 70 further comprises an input 73 of the signal contact with the skin, which is connected to the sensor 13 contact with skin and includes a lamp 20 only if the signal is accepted at the input 73 of the signal contact with skin, indicates the presence of skin contact. The sensor 13 skin contact may be, for example, a mechanical sensor, which is displaced upon contact with the skin, an optical sensor, an ultrasonic sensor, a capacitive sensor, etc.

In a more preferred embodiment, the device 1 contains multiple sensors contact with the skin, located on opposite sides of the socket 12, and the control device 70 includes a lamp 20 only if the signals received from all of the sensors in contact with the skin, indicate the presence of skin contact.

During operation, the control device 70 controls the lamp 20 so that the lamp is switched short pulses, with pulse duration in the range from 1.1 MS to 1.9 MS. The preferred setting of the pulse width is approximately equal to 1.8 MS. In this context, the duration of the pulse is measured at a height of 50% of the maximum light intensity as the lamp is required is camping some time to increase the light intensity from zero, and the lamp takes some time to reduce the intensity of light back to zero.

The flux density at the skin level is set in the range from 2 to 7 j/cm2(integral value in the working spectral range from 575 nm to 1000 nm) on the pulse, depending on skin type. It should be noted that any radiation in the spectral range of wavelengths above 1000 nm is not considered in the above value of flux density.

The generally accepted classification system of the skin developed in 1975, Dr. of medicine and Dr. of philosophy Thomas b Fitzpatrick (Thomas B. Fitzpatrick, MD, PhD of Harvard medical school. The system of classification of skin color-based and external structure of the skin and reactions on exposure to sunlight and contains the following types with the following characteristics:

TYPE I:Very light skin, blond/red hairAlways burns, never tans
TYPE IILight skinEasily gets burns
TYPE IIISlightly dark skinGets burns, then tans
TYPE IV Light brown leatherTans easily, with minimal burns
TYPE VLight black leatherDark tan, with an extremely rare burns
TYPE VIVery dark skinDark tan, never gets burns

As mentioned above, the input element 14 may enable the user to enter the type of skin, and the user may receive, for example, information relating to the skin type of leadership and descriptions or sample images or similar informative materials. For skin types on the system Fitzpatrick control unit 70 sets the flux density at the skin level in the range of:

5 to 7 j/cm2for types I, II, III skin;

4 to 6 j/cm2for type IV skin;

3 to 5 j/cm2for type V skin; and

2 to 3 j/cm2for type VI skin.

Usually if the input element 14 is able to enter only the skin type, the control device 70 preferably sets the flux density at the skin level at the maximum value of the above-mentioned ranges, ie,

approximately 7 j/cm2for types I, II, III skin;

approximately 6 j/cm2for type IV skin;

priblizitelen is 5 j/cm 2for type V skin; and

approximately 3 j/cm2for type VI skin.

Usually if the input element 14 allows the user to make fine adjustment in accordance with a specific tolerance or sensitivity of the user, in the range from MINIMUM (MINIMUM) and MAXIMUM (MAX), the control device 70 preferably sets the flux density at the skin level at the maximum value of the above-mentioned ranges, when the user assigns a MAXIMUM, i.e. at

approximately 7 j/cm2for types I, II, III skin;

approximately 6 j/cm2for type IV skin;

approximately 5 j/cm2for type V skin; and

approximately 3 j/cm2for skin type VI;

and preferably sets the flux density at the skin level to the minimum value of the above-mentioned ranges, when the user assigns a MINIMUM, ie,

approximately 5 j/cm2for types I, II, III skin;

approximately 4 j/cm2for type IV skin;

approximately 3 j/cm2for type V skin; and

approximately 2 j/cm2for type VI skin.

The user may not be required to enter your settings for your skin type as the input element allows the user to select a continuous adjustment of the flux density from the MINIMUM (MINIMUM) and MAXIMUM (MAX). The input element can be performed, for example, as a rotary knob, and the control unit 70 sets the value of the flux density at the skin level in the range from 2 to 6 j/cm2in linear dependence on the user settings (position of the head rotation) between the MINIMUM position and MAXIMUM position.

For hair removal above the flux density should lead to the skin within a time interval having the above-mentioned duration. In this respect no matter fed does light within time interval continuously, i.e. as one continuous flash or continuous pulse, or light within time interval is supplied intermittently, i.e. as a sequence of subimperial, the sequence will continue to be called "impulse". Several pulses of light to one area of the skin is not required. For processing zones of the skin, beyond the treatment area (i.e. the size of the window 11) of the device, the user must move the device from one zone of the skin to another and repeat the process. The device may contain user-driven input trigger signal, for example, a push button, which the user actuates when the user is ready to apply another light pulse. The controller 70 may also be initiated by the lamp again, for example, with a pulse repetition frequency in diapazonom 0.1 Hz to 0.5 Hz, that gives the user time to move the device between pulses. As mentioned above, the light pulse is preferably not supplied, if skin contact is missing.

In professional systems at high flux density it is necessary to filter out light having wavelengths above 1000 nm, for the relief of pain. Due to the relatively low flux density present invention eliminates the necessity of eliminating the above-mentioned wavelengths and, thus, provides savings. In addition, given the relatively low flux density lamp generates relatively little heat, which can be defined using a simple fan that eliminates the need for complex and heavy equipment cooling. In addition, also due to the relatively low flux density there is no need for skin cooling gel or similar tool.

The device 1 is preferably provided with a thermometric means for generating a signal indicating the temperature of the lamp, for example, a temperature sensor 80 mounted near the lamp 20 to control its temperature. Control device 70 further comprises an input 78 of the temperature signal, which is connected to the temperature sensor 80. The controller 70 compares the temperature signal with a pre-selected by ohavim signal and provides the lamp 20, only if the temperature of the lamp is below the threshold temperature. Although the invention is shown in detail in the drawing and is explained in the above description, a person skilled in the technical field, it must be clear that the picture and description should be considered illustrative and exemplary, and that neither the picture nor the description does not limit the invention. The present invention is not limited to the described variants of implementation; on the contrary, within the protected scope of the invention possible individual variations and modifications, as defined in the attached claims.

For example, instead of or in addition to battery power, the device can be equipped with a power cord to connect to the network.

In addition, the operating range from 545 nm to 1200 nm is the preferred range, but there may be some small changes within a given range. It is sufficient if the light is radiated in a wide spectral range suitable for effective hair removal.

Additionally, you may split open.
