Definitions
- the invention concerns devices for the safe, painless and permanent removal of unwanted hairgrowth in accordance with the specification in claim 1.
- U.S. Patent No. 5.226.907 proposes the use of a CO2 laser with a wavelength of ca. 10.000 nm, or a pulsed dye laser with wavelengths of 531 , 584, 587 or 632 nm.
- the applicator covers a treatment area of ca. 1 cm2, and the radiation intensity is from 5 to 10 J/cm2.
- a photosensitizer such as a suspension of carbon in oil, which must penetrate through to the hair-roots via the pores.
- WO 95/15725 proposes, for the same purpose, a ruby laser with a wavelength of 694 nm, a neodyme-YAG laser with a wavelength of 1064 nm, or the use of any other laser with a wavelength of between 600 and 1500 nm.
- the pulse-length should be between 1 ⁇ sec. and 1 millisec.
- U.S. Patent No. 5.059.192 describes the use of a ruby laser which emits a light-pulse of 30-40 nsec, treating an area of ca. 3 mm. with an intensity of 0,4 to 10 J/cm2.
- the irradiation time should be under 2 msec.
- U.S. Patent No. 4.388.924 proposes the use of an argon laser with a wavelength of between 480 and 520 nm.
- the laser-beam should have a strength of 0,5 to 2,5 W and the treatment time be between 10 and 400 msec.
- the light is transferred from the laser to the applicator by means of photo-optic fibres.
- U.S. Patent No. 4.608.978 describes a device for the removal of unwanted body-hair with the use of a flashtamp.
- the flashlamp is located in the main unit of the apparatus, the light being conveyed to the applicator by means of photo-optics. No reference is made to the wavelength of the light, but it is known that the light from a flashlamp lies in the wavelength area of 180 to 2000 nm.
- U.S. Patent No. 5.066.293 proposes the use of an adjustable dye-laser for derma- tological applications.
- the skin should be pretreated with a light-absorptive suspension, i.e. a photosensitizer.
- GB 21 23 287 describes a device for the removal of unwanted body-hair which entails that each individual hair must be threaded into an opening in the hand- applicator. Albeit that this method is probably gentler with the surrounding dermal tissue, the threading of each individual hair is so time-consuming as to render the method impractical. In practice, areas of skin are always treated, in facial areas with a beam of 10 mm diameter and in body areas with a beam of 30 mm diameter.
- the invention addresses the task of improving the characteristics of devices for the removal of unwanted body hair through the following aims; to ensure patient safety from tissue damage in the event of technical or human operational error, to be cheaper, and to enable a painless treatment without side-effects.
- the task is solved through two devices.
- the first device which is the subject of patent claim 1 , uses as its light-source at least one semiconductor diode and / or at least one laser diode, whereby the light-source is adjustable according to the colour of the hair and the skin type.
- the second device uses a flashlamp as its light-source, with colour filters which can be changed according to the hair colour and skin type.
- the light-source contains at least one adjustable laserdiode.
- Laserdiodes whose wavelength can be adjusted by means of a piezo-element are customary.
- the light-source contains at least one semiconductor diode which can produce light of different wavelengths. It is known that certain LED-diodes, with suitable input, can emit light at wavelengths of 600, 900 and 1200 nm.
- the light-sources should preferably contain several semiconductor and / or laser diodes which can emit light at different wavelengths. Therefore the radiation from the diodes should preferably be individually selectable - switched ON or OFF, thus rendering it possible to adjust both the radiation power and wavelength of the inventions.
- a further development of the device is the inclusion of a photosensor in the applicator which senses the light reflected from the skin.
- the photosensor enables a fully automatic tuning of the light intensity and most particularly of the wavelength.
- a further sensor which monitors the contact of the applicator with the patient's skin and immediately switches off the beam if the contact is broken.
- Fig.4 a further device for the removal of unwanted body hair
- Fig.5 a second applicator for use with the device in fig.4. Detailed description of the invention:
- Fig.1 shows a control and power unit 10 in its casing, with buttons 11 for adjustment of treatment time, frequency, intensity, radiation intensity in J/cm2 etc.
- the installed values can be read on a display 12. Access is subject to a personal passcode.
- the control and power unit 10 can be run either from 110/230 V AC or from low-voltage DC. Four different applicators can be connected to the control and power unit 10.
- Fig.2 shows a first applicator which is connected to the control and power unit 10 by means of cable 13.
- the applicator- housing has a start-button 19 and a standby indicator 18.
- a light-source and an optic are installed in the front casing 14. Part 14 is interchangeable.
- a contact-sensor 9 registers the applicator's contact with the skin 2.
- Fig 3. shows a light-source 20 and the pertaining optics 16,16'.
- a printed circuit- board 21 twelve LED-diodes 22 and four laser diodes 23 are installed.
- the radiation from the diodes 22 and 23 are individually selectable - switched ON or OFF. They emit light of different wavelengths. This enables the adaptation of radiation intensity and wavelength to the colour of the hair 1 and the type of skin 2.
- the light emitted by the diodes 22, 23 is first concentrated in the lenses 16, 16', before it reaches the skin.
- a photosensor 24 is located in the centre of the printed circuit-board 21 . This receives the light which is reflected back from the skin. This feedback signal is used in the control and power unit to regulate the radiation intensity and the wavelength of the light-source semi- and fully-automatically.
- Fig.4 shows a second device for the removal of unwanted body hair.
- This consists of a control and power unit 10', with a flashlamp 20' as light-source.
- the colour filters 25 In front of the flashlamp 20' are the colour filters 25, by means of which the light can be filtered to an optimal wavelength in the range 180 to 2000 nm for the respective patient.
- the filtered light is conducted by means of optic fibres 17 to an applicator 15 where it is focused by optic 16.
- the treatment procedure is started with start-button 19.
- the tip of the applicator 15 has a diameter of eg. 10 mm and is thus suitable for the depilation of facial skin.
- Fig 5 shows an applicator 15' with a tip of ca. 30 mm diameter, which is suitable for the depilation of body areas.
- the invention is intended for medical and / or cosmetic skin treatment.
