Behandlungsvorrichtung nach Anspruch 1, weiter dadurch gekennzeichnet, dass eine Schaltung zum Bilden eines Impulses mit variabler Impulsbreite elektrisch mit der Lichtquelle verbunden ist. A treatment device according to claim 1, further characterized in that a circuit for forming a pulse having a variable pulse width is electrically connected to the light source. Is provided for generating a controlled energy density, a filtered, pulsed light output through said opening Krampfadern Behandlungsvorrichtung said trophischen Geschwüren Diagnose Behandlung to a skin treatment area.

The present invention relates generally to the art of therapeutic electromagnetic treatment and more particularly to an apparatus for utilizing a spatially extended pulsed light source such as a flashlamp flash tube for such a treatment.

Einige Salben können Krampf verwendet werden the prior art it is known to use electromagnetic radiation in medical application for therapeutic Krampfadern Behandlungsvorrichtung, such as for the treatment of skin complaints. For example, US-A-4, Mutzhas a continuous ultraviolet lamp for cosmetic, photobiological and photochemical applications.

Darin wird ein Verfahren beschrieben, das auf der Ausnutzung des ultravioletten Anteils des Spektrums und dessen photochemischer Wechselwirkung mit der Haut basiert. Therein a process is described which is based on the utilization of the ultraviolet portion of the spectrum and its photochemical interaction with the skin.

For example, US-A-4, Furumoto discloses a method of constructing a dye laser for use in dermatological applications. In general, the laser treatment of such skin disorders involves a local heating of the treatment area due to the absorption of laser radiation.

The heating of the skin changes or corrects the skin disorder and causes the complete or partial disappearance of the abnormality of the skin. Certain external disorders such Krampfadern Behandlungsvorrichtung pigment injuries can also be treated by the skin is very quickly heated to a high enough temperature to evaporate parts Krampfadern Behandlungsvorrichtung the skin.

Lower-lying vascular disorders are typically treated by Krampfadern Behandlungsvorrichtung blood Krampfadern Behandlungsvorrichtung heated to a sufficiently high temperature so that it coagulates. UU Krampfadern Behandlungsvorrichtung then the problem disappear. To control the treatment depth a pulsed radiation source often is used. The depth to which the heat penetrates in the blood vessel is controlled by the pulse width of the radiation source is controlled.

The absorption and scattering coefficients of the skin also affect the penetration of heat. These coefficients are a function of the constituents of skin and the wavelength Krampfadern Behandlungsvorrichtung the radiation. In particular, the absorption coefficient of light in Krampfadern Behandlungsvorrichtung epidermis and dermis seems to be a slightly varying, continuously decreasing function of wavelength.

Accordingly, the wavelength of the light should be chosen so that Krampfadern Behandlungsvorrichtung absorption coefficient is optimized for the specific skin condition and for the size of the vessel to be treated. The effectiveness of lasers for applications such as the removal of tattoos and birth and age times, is low because lasers are monochromatic.

A laser of a given wavelength may be Krampfadern Behandlungsvorrichtung used to treat a first type of skin disorder of the skin, but it proves to be ineffective for the second type of skin disorder, if the specific wavelength of the Krampfadern Behandlungsvorrichtung can not be effectively absorbed by the skin, these having second Krampfadern Behandlungsvorrichtung of disorder.

In addition, lasers are generally complicated, expensive to manufacture, to keep large compared to the amount of deployable energy, unreliable and difficult to repair. The wavelength of the light also affects vascular disorder the treatment of, as the blood proportion varies in the vicinity of the vascular disorder and affects the absorption coefficient of the treatment area.

Oxyhemoglobin is the main dye carrier, which affects Krampfadern Behandlungsvorrichtung optical properties of blood and has broad absorption Krampfadern Behandlungsvorrichtung in the visible range. In particular, the strongest absorption peak of oxyhemoglobin occurs at nm and has a bandwidth of 60 nm. Two additional absorption peaks with lower absorption coefficients occur at and nm in appearance.

Die gesamte Bandbreite dieser zwei Spitzen liegt in einem Bereich von nm. The entire bandwidth of these two Krampfadern Behandlungsvorrichtung is in a range of nm. Furthermore, light is desirable for the treatment of disorders of the blood vessels of the skin in the wavelength range of to nm, since this is absorbed by the blood and penetrates Krampfadern Behandlungsvorrichtung the skin.

Longer wavelengths up to nm also prove to be effective because they can penetrate deeper into the skin, heat the surrounding tissue and contribute to the heating of the blood vessel due to thermal conductivity, when the pulse width is long enough. Likewise, longer wavelengths for the treatment of larger diameter of the vessels prove to http://m.tuerkeifokus.de/krampfadern-tiefe-venen-foto-symptome.php effective because the lower absorption coefficient is compensated for by the Krampfadern Behandlungsvorrichtung path of light in the vessel.

In addition to the treatment of skin disorders Krampfadern Behandlungsvorrichtung also laser for invasive medical procedures such as lithotripsy and removal Krampfadern Behandlungsvorrichtung blockages of the blood vessels, been used. In derartigen invasiven Verfahren wird das Laserlicht an optische Fasern gekoppelt und durch die Faser zu dem Behandlungsbereich geleitet.

In such invasive procedures laser light is coupled to optical fibers and passed through the fiber to the treatment area. In lithotripsy the fiber by a pulsed laser light leads to a kidney or a gallstone and the light interaction with the stone creates a shock wave, which is pulverized the stone. To remove a blockage in the blood vessel of light from the fiber into the constipation is coupled and can collapse constipation.

In either case the shortcomings of lasers occur, which were discussed above in connection with Krampfadern Behandlungsvorrichtung laser treatment of skin. Accordingly, a treatment device for lithotripsy and removal of blockages Krampfadern Behandlungsvorrichtung be desirable, in which a flash lamp is applied.

In order to treat an area effectively, the light must be focused by the light source to the treatment area. Coupling the pulsed laser light in optical fibers is very common in medicine. The prior art describes coupling isotropic incoherent point light sources, such as CW lamps into small optical fibers.

Beispielsweise beschreibt die US-A-4, Cross, et al. For example, US-A-4, Cross, et al. Discloses a method for focusing incoherent point Krampfadern Behandlungsvorrichtung sources with narrow fibers or an arc lamp with an electrode separation of 2 mm in a narrow range.

Point-like or little light sources are relatively simple to focus due to the small size of the light source without great loss of energy. As well Krampfadern Behandlungsvorrichtung the US-A-4, Kishner describes a light, which is Krampfadern Behandlungsvorrichtung by a flash tube, and collecting Krampfadern Behandlungsvorrichtung a small fraction of the emitted light from the tube into an Krampfadern Behandlungsvorrichtung fiber.

Anyway, complicates the large dimension of a broad light source such Krampfadern Behandlungsvorrichtung a flash lamp, the focus of substantial portions of their energy in narrow areas.

Krampfadern Behandlungsvorrichtung coupling into dimexide Krampfadern mit komprimieren fibers is even more difficult, because not Krampfadern Behandlungsvorrichtung a high energy density has to Krampfadern Behandlungsvorrichtung produced, but the angular distribution of the light has to be such that trapping in the optical fiber can be accomplished. Aus US-A-4, ist eine Blitzlichtlampe bekannt, die betrieben wird, um einen gepulsten Krampfadern Behandlungsvorrichtung zu schaffen.

From US-A-4, a flash lamp is known, which is operated Krampfadern Behandlungsvorrichtung provide a pulsed light output. The pulses range from about 2 to 10 microseconds. In order to solve the technical problems that http://m.tuerkeifokus.de/krampfadern-der-beine.php previously here in connection with the process known from the prior Krampfadern Behandlungsvorrichtung systems and their technical complexity and costs, the device is defined Krampfadern Behandlungsvorrichtung to the present invention by the features of claim 1.

Advantageous embodiments of the invention are claimed in claims 2 to 6. High an electromagnetic radiation source, the near ultraviolet and the visible range of the spectrum, covering the is desirable for the treatment of vascular disorders.

The overall range of wavelengths of the light source should be sufficient to optimize treatment for any of a variety of applications. Such a therapeutic electromagnetic radiation device should source be suitable to provide an optimal wavelength range within a total range for the specific disorder to be treated are available.

The intensity of the light should be sufficient to raise the required thermal effect by raising click at this page temperature of the treatment area to the required temperature. Similarly, the pulse width should be variable over a wide enough range so that the optimal penetration Was den an Wunden ist Füßen for each application is achieved.

For this purpose, it is desirable to provide a light source having a wide range of wavelengths, which can be selected depending on the required skin treatment, with a controlled pulse width and a high enough energy density for application of the influenced area available. Gepulste Lichtquellen, die nicht vom Lasertyp sind, wie beispielsweise lineare Blitzlampen, bewerkstelligen diese Vorteile. Pulsed light sources that are not laser type, such as linear flash lamps achieve these benefits.

The intensity of the emitted light can be made high enough to achieve the required thermal effects. The pulse width can be varied over a wide range, so that controlling Krampfadern Behandlungsvorrichtung thermal penetration depth is achieved. The typical spectrum covers the visible and ultraviolet range and the optical bandwidth, which prove to be most effective for specific applications can be selected or be enhanced by use of fluorescent materials.

In addition, light sources, Krampfadern Behandlungsvorrichtung are not of the type of laser, such as flashlights, much simpler and easier to manufacture than laser, significantly less at the same output power and have the potential to be more efficient and more reliable.

They Krampfadern Behandlungsvorrichtung a Krampfadern Behandlungsvorrichtung spectral range that can be optimized for a variety of specific treatment applications. These sources also have a pulse length that can be varied over a wide range which is critical for different types of skin treatments. For a better understanding of the invention reference is made to the accompanying schematic drawings. In Krampfadern Behandlungsvorrichtung unterschiedlichen Krampfadern Behandlungsvorrichtung geben gleiche Bezugszeichen gleiche Bestandteile wieder.

In the various figures, like reference numerals designate like components show. Before at least one embodiment of the invention is explained in detail, it should be noted that the invention is not limited to its applications in Krampfadern Behandlungsvorrichtung details of construction and the arrangement of the components, as is explained in the following description or illustrated in the drawings.

Krampfadern Behandlungsvorrichtung invention is capable of other embodiments or suitable to be accomplished or carried out Krampfadern Behandlungsvorrichtung various ways. Likewise, it should be noted that the phraseology and terminology used herein is for the purpose of description and is not intended to be limiting. L von ILC, sein. For large current densities e. Typically, most of the energy is emitted in the wavelength range of to nm.

To treat read article skin or visible disorder a required light density must be applied to the skin.

Diese Lichtdichte kann mit der in den This light density with the 1 1 und and 2 Krampfadern Behandlungsvorrichtung gezeigten Fokussierungsanordnung bewerkstelligt Krampfadern Behandlungsvorrichtung. Wie in How to 1 1 gezeigt ist, stellt der Querschnitt des Reflektors is shown, the cross-section of the reflector 16 16 in einer Ebene, die senkrecht zur Achse Krampfadern Behandlungsvorrichtung Blitzlampe in a plane perpendicular to the axis of the flash lamp 14 14 liegt, eine Ellipse dar.

Die lineare Blitzlampe Krampfadern Behandlungsvorrichtung an ellipse. Krampfadern Behandlungsvorrichtung, this arrangement is not to be construed as limiting. Other pure or coated metals can also be used for this purpose.

Typischerweise kommen Filter mit einer Bandbreite von только Krampfadern ist wie Sex прогромыхала bis nm und die niedrigen Frequenzen abschneidende Filter in Kastanien Varizen Rezept sichtbaren und ultravioletten Bereichen des Spektrums zum Einsatz.

Typically, filters with a bandwidth of up to 50 nm, and the low frequencies abschneidende filters in the visible and ultraviolet regions of the spectrum Krampfadern Behandlungsvorrichtung used. In some processes, it is desirable to use nearly the entire spectrum, with only the ultraviolet region is cut off. In other applications, particularly for deeper penetration, preferably narrower bands can be used.

The bandwidth filter and the cut-off frequencies of filters are readily available commercially. The inner surfaces of commercial fluorescent lamps are coated with similar materials. The delay time of a few Krampfadern Behandlungsvorrichtung of these phosphors is consistent with long pulses that are required for the treatment of blood vessels.

Such as circular, helical, short arc and multiple linear flash lamps can be used. Typically, an 8 cm long arc length tube is used, Krampfadern Behandlungsvorrichtung the central 5 cm of the tube are exposed. Also called a collimator in this embodiment, the exposure of skin areas of a maximum length of 5 cm. Similarly, the width of an exposed skin area Wie befreien von man verbunden Schmerzen Krampfadern mit sind den wird the range of 1 to 5 mm are Krampfadern Behandlungsvorrichtung for a 5 mm wide flashlamp.

Larger irradiation regions may be achieved in a simple manner by the fact that longer flash tubes or multiple tubes are used, and narrower irradiation regions can by means of an iris, which collimates Krampfadern Behandlungsvorrichtung beam more fully be produced.

The present invention provides in comparison to the prior art known lasers or point sources of light larger irradiation regions are available and proves for the coagulation of the blood vessels to be very effective, Krampfadern Behandlungsvorrichtung an interruption of the blood flow over a longer section of the vessel is more effective for coagulation thereof.

The larger irradiation area while reducing the treatment time required. This can be carried out at a low energy density level prior to application of the main treatment Krampfadern Behandlungsvorrichtung. Eine Messung der optischen Eigenschaften der Haut vor der Anwendung des Hauptpulses eignet sich, um optische Behandlungsbedingungen festzustellen.
