Abstract
Description
Beschreibung description
Die Erfindung betrifft eine neue Anwendung von üblicherweise auf medizinischem Gebiet verwendeten Lasern.The invention relates to a new application of what is usually medical Area used lasers.
Die Behaarung des menschlichen Körpers ist bekanntlich recht verschieden. Neben Menschen mit dünner Behaarung mit verhältnismäßig wenig kurzen, unauffälligen Haaren gibt es andere, die sehr dicht, lang und auffallend mit starken Haaren behaart sind. Vor allem bei letzteren besteht zuweilen der Wunsch, von auffälliger Behaarung teilweise oder weitestgehend befreit zu werden, um das persönliche Wohlbefinden zu steigern.The hairiness of the human body is known to be quite different. In addition to people with thin hair with relatively little short, inconspicuous There are other hairs that are very dense, long and conspicuously hairy with thick hair are. Especially in the latter, there is sometimes a desire to have conspicuous hair to be partially or largely freed for personal well-being to increase.
Dazu wurde bisher eine Mikrowellentechnik angewandt: Eine Nadel wurde jeweils in die Haarwurzel gestochen und diese mit Hilfe von Mikrowellen zerstört. Es ist einzusehen, daß dieses Verfahren recht mühsam, unangenehm und auch in gewissem Umfang gefährlich ist, da die Gefahr von Infektionen und Narbenbildung groß ist. Zudem ist diese herkömmliche Technik auch recht zeitaufwendig.To this end, a microwave technique has been used up to now: a needle has been used pricked into the roots of the hair and destroyed with the help of microwaves. It is to be understood that this procedure is quite tedious, uncomfortable and also in a certain way Scope is dangerous as the risk of infection and scarring is great. In addition, this conventional technique is also quite time-consuming.
Aufgabe der Erfindung ist es daher, diese herkömmliche kosmetische Behandlung zu verbessern, insbesondere angenehmer, rascher durchführbar und unter dem Gesichtspunkt der Infektionsgefahr und der Narbenbildung auch sicherer zu machen.The object of the invention is therefore to provide this conventional cosmetic Improve treatment, especially more comfortable, quicker and under also make it safer from the point of view of the risk of infection and scarring.
Diese Aufgabe wird erfindungsgemäß durch die Anwendung eines medizinischen Lasers zur Enthaarung gelöst. Dabei ist mit dem Ausdruck "medizinischer Laser" ein solcher gemeint, wie er üblicherweise für medizinische und augenoptische Zwecke Verwendung findet. Besonders hat sich in der Praxis der bekannte Typ des CO2-Lasers bewährt.This object is achieved according to the invention through the use of a medical Laser solved for depilation. The term "medical laser" is used here meant as it is commonly used for medical and ophthalmic Purposes Is used. The well-known type of CO2 laser has proven particularly useful in practice proven.
Die erfindungsgemäße Anwendung nutzt die Wärme, die von einem Laser-Lichtstrahlenbündel (bevorzugt CO2-Emission) hervorgerufen wird, das durch ein optisches Faserkabel an die Haarwurzel gelangt, die dann zerstört wird.The application according to the invention uses the heat generated by a laser light beam (preferably CO2 emissions) caused by an optical fiber cable reaches the hair root, which is then destroyed.
Die erfindungsgemäße Anwendung des Lasers zur Haarentfernung hat gegenüber der herkömmlichen Methode verschiedene Vorteile: Sie führt nicht zu Infektionen und Narbenbildung, und die Wirkung wird erheblich rascher erzielt.The use according to the invention of the laser for hair removal has opposite There are several advantages to the conventional method: It does not lead to infections and scarring, and the effect is achieved much more quickly.
-Für die erfindungsgemäße Anwendung des Lasers zur Haarentfernung sind die im Einzelfall geeignetsten Bedingungen vom Fachmann leicht festzustellen. So hängt die vom Laser-Lichtstrahl übertragene Energiemenge (und in Abhängigkeit von ihr die Intensität bzw. die Bestrahlungszeit) von der Dicke des Haares ab, und die Optimalwerte der Strahlungsstärke und der Bestrahlungszeit sind leicht zu ermitteln, indem man mit einer milden Anwendung, also geringer Leistung und kurzer Bestrahlungszeit, beginnt, und stufenweise steigert, sofern nicht bereits die Erfahrungswerte vorliegen. Im allgemeinen läßt sich aber sagen, daß ein durch eine Linse fokussierter Strahl von 0,5 W Leistung für etwa 0,5 bis 2 s angewandt wird, während ein nicht-fokussierter #Strahl von 1 W für eine Zeit in der Größenordnung einer Sekunde angewandt wird. Üblicherweise erfolgt die Anwendung eines C02-Lasers mit einer Leistung von etwa 0,5 bis 2 W.-For the use according to the invention of the laser for hair removal the most suitable conditions can easily be determined by a person skilled in the art. The amount of energy transmitted by the laser light beam (and depending on from it the intensity or the irradiation time) from the thickness of the hair, and the optimal values of the radiation intensity and the radiation time are easy to determine, by using a mild application, i.e. low power and short irradiation time, begins, and increases gradually, unless the empirical values are already available. In general, however, it can be said that a beam focused through a lens 0.5 W power is applied for about 0.5 to 2 s, while a non-focused one # 1 W beam is applied for a time on the order of a second. Usually, a CO2 laser is used with a power of approx 0.5 to 2 W.
Besonders bewährt haben sich Anwendungsbedingungen innerhalb dieser Bereiche von kurzer Bestrahlungszeit bei relativ hoher Leistung.Application conditions within these have proven particularly useful Areas of short exposure time with relatively high power.
In der Praxis wird der optische Lichtleiter möglichst nahe an den Ort der Wirkung des Laser-Strahls, also die Haarwurzel, herangeführt und diese durch die Strahlungswärme zerstört. Dadurch entfällt natürlich sowohl die unangenehme Empfindung des Einstechens einer Nadel (wie für die Mikrowellenbehandlung) als auch die Gefahr von Infektionen und Narbenbildung. Ferner entfällt die bisherige Notwendigkeit der Durchführung der Enthaarung durch Mediziner (wie im Falle der Enthaarung durch Mikrowellenbehandlung), vielmehr erfolgt die erfindungsgemäße Anwendung durch Kosmetiker, die nunmehr diese kosmetische Haarentfernung zudem noch rascher durchzuführen in der Lage sind.In practice, the optical light guide is as close as possible to the Place of action of the laser beam, i.e. the hair root, introduced and destroyed them by the radiant heat. This of course eliminates both the uncomfortable sensation of sticking a needle (as for microwave treatment) as well as the risk of infection and scarring. Furthermore, the previous one is no longer applicable Need for medical professionals to perform depilation (as in the case of the Depilation by microwave treatment), rather the application according to the invention takes place by beauticians, who now also do this cosmetic hair removal even faster are able to perform.
