Abstract

The invention relates to a device for dry and wet therapy of disorders, in particular in dermatology and paronychia, using ultrasound. The device consists of an electronics part (1) for control purposes with an attached ultrasonic transducer (2), at least one transducer being arranged in a pot-shaped manual transducer housing (3) on which on the one hand a preferably adjustable hand grip (9) and on the other hand a membrane (6) in front of the transducer is arranged with a water-tight housing connection, followed by a second membrane (7) which surrounds a liquid or water cushion (8) and through which the acoustic oscillations can be transmitted upon application to the treatment area, for use in the frequency range between 30 and 80 kHz, in particular at 50 kHz.

Description

Die Erfindung bezieht sich auf ein Gerät zur Nassbehandlung bei Ultraschalltherapie, insbes. der Dermatologie und Paronyhie mit den Merkmalen nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for wet treatment in ultrasound therapy, in particular dermatology and paronyhia with the features according to the preamble of claim 1.

Durch die EP-A-0 320 444 ist ein Gerät bekannt, welches ein Elektronikteil zur Regelung mindestens eines Ultraschallschwingers umfasst. Der Ultraschallschwinger ist in einem topfförmigen Handschwingergehäuse angeordnet. Dem Ultraschallschwinger ist eine Membrane vorgelagert. Das durch die EP-A-0 320 444 bekannte Gerät dient zur Diagnostik, insbesondere zur Erkennung von Tumoren.From EP-A-0 320 444 a device is known which comprises an electronic part for controlling at least one ultrasonic vibrator. The ultrasonic transducer is arranged in a pot-shaped handheld transducer housing. A membrane is placed in front of the ultrasonic transducer. The device known from EP-A-0 320 444 is used for diagnostics, in particular for the detection of tumors.

Für die Ultraschalltherapie sind Badeeinheiten bekannt in Form von Flüssigkeitsbehältern mit eingebauten Ultraschallgebern, welche Einheit zur Behandlung beim Eintauchen der erkrankten Körperteile dienen. Je nach Wannengröße sind diese Einheiten stationär oder auch mobil einzusetzen, wie dies z.B. die EPA 0 301 162 zeigt. Hierdurch wird die Durchblutung und Reinigung der zu behandelnden Körperteile und damit die Heilwirkung verbessert. Diese Badeeinheiten haben aber den Nachteil unhandlich und sperrig zu sein; sie haben einen entsprechenden Platzbedarf nötig und eignen sich daher für Therapieanstalten und weniger für den Privatgebrauch. Ausserdem gibt es auch schon kleine Geräte in Form von Fußwannen für die Naßbehandlung.Bath units are known for ultrasound therapy in the form of liquid containers with built-in ultrasound transmitters, which units are used for treatment when the diseased parts of the body are immersed. Depending on Trough size, these units can be used stationary or mobile, as shown, for example, by EPA 0 301 162. This improves the circulation and cleansing of the parts of the body to be treated and thus the healing effect. However, these bathing units have the disadvantage of being bulky and bulky; They require a corresponding amount of space and are therefore suitable for therapy institutions and less for private use. In addition, there are already small devices in the form of foot tubs for wet treatment.

Die Aufgabe besteht darin, ein Handgerät zum vielseitigen mobilen Einsatz zu schaffen, welches in Verbindung mit einer vorhandenen Wanne bei Nassbehandlung denselben Zwecken mit gleicher Effizienz dienen kann.The task is to create a handheld device for versatile mobile use, which in connection with an existing tub can serve the same purposes with the same efficiency with wet treatment.

Das Gerät zur Nassbehandlung bei Ultraschalltherapie zeichnet sich dadurch aus, dass der der Membrane nachgeordnete Rand des offenen Handschwingerghäuses mit Durchbrüchen versehen ist. Beim Eintauchen in eine Flüssigkeit bildet sich in dem offenen Handschwingergehäuse, begrenzt durch den mit Durchbrüchen versehenen Rand, ein Flüssigkeitspolster. Durch dieses Flüssigkeitspolster sind die Ultraschallschwingungen bei Auflage an der in einem Flüssigkeitsbehälter eingetauchten Behandlungsstelle übertragbar. Das Gerät wird vorzugsweise im Frequenzbereich zwischen 30 bis 80 kHz, insbes. bei 50 kHz verwendet.The device for wet treatment in ultrasound therapy is distinguished by the fact that the edge of the open hand-held vibrator housing located downstream of the membrane is provided with openings. When immersed in a liquid, a liquid cushion forms in the open hand-held vibrator housing, delimited by the perforated edge. Through this liquid cushion, the ultrasonic vibrations can be transmitted when placed on the treatment site immersed in a liquid container. The device is preferably used in the frequency range between 30 to 80 kHz, in particular at 50 kHz.

Weitere Einzelhtein des Geräts gemäss der Erfindung sind anhand eines Ausführungsbeispiels für die Naßbehandlung in der Zeichnung dargestellt und nachfolgend beschrieben und zwar zeigen:

Further details of the device according to the invention are shown in the drawing using an exemplary embodiment for the wet treatment and are described below and show that:

Nach Figur 1 entsprechend dem Ausführungsbeispiel besteht das Gerät aus einem Elektronikteil 1 mit Zuleitung 1a zum Ultraschallschwinger 2a im Handschwingergehäuse 3a mit bei 4a schwenkbar vorgesehenem Handgriff 5a. Das Gehäuse 3a ist in zylindrischer Form aus Edelstahl gefertigt mit wasserdicht vorgesetzter Edelstahlmembrane 6a, mittels Silikonring 6c abgedichtet, hinter welcher der Schwinger 2a angeordnet ist. Der Membrane 6a ist ein mit Durchbrüchen versehener Rand 7a nachgeordnet. In der dargestellten Ausführungsform ist der Rand 7a des Gehäuses 3a wellenförmig ausgebildet. Bei Auflage an der in einem Flüssigkeitsbehälter eingebrachten Behandlungsstelle werden somit die Schallschwingungen über das durch den Gehäuserand mit Seitenöffnungen zwischenliegendem Wasserpolster übertragen. Hierbei bildet sich infolge des Wellenrandes eine gute Wasserverwirbelung, welche zu einem schnellen Behandlungserfolg führt.According to FIG. 1 in accordance with the exemplary embodiment, the device consists of an electronic part 1 with a lead 1a to the ultrasonic vibrator 2a in the handheld vibrator housing 3a with a handle 5a pivotably provided at 4a. The housing 3a is made in a cylindrical shape from stainless steel with a waterproof stainless steel membrane 6a, sealed by means of a silicone ring 6c, behind which the oscillator 2a is arranged. The membrane 6a is followed by an edge 7a provided with openings. In the illustrated embodiment, the edge 7a of the housing 3a is wave-shaped. When placed at the treatment point placed in a liquid container, the sound vibrations are thus transmitted via the water cushion located through the edge of the housing with side openings. As a result of the wave edge, a good swirling of water forms, which leads to a quick treatment success.

Am topfförmigen Handschwingergehäuse 3a und zwar am Gehäuseboden ist gemäß der Figur 2 ein schwenkbarer Handgriff 5a vorgesehen, welcher zwichen der geschlitzten Segmentaufnahme 10 mit eingebrachtem Kunststoffsegment 11, das mit Seitenstutzen 12 verschwenkbar in der Segmentaufnahme 10 gehalten ist, als Griffbolzen 13 eingeschraubt. Der Griffsbolzen 13 ist in seiner verschwenkten Lage durch weiteres Einschrauben bis auf den Grund 14 der Segmentaufnahme 11 in seiner Schwenkstellung festlegbar.According to FIG. 2, a pivotable handle 5a is provided on the pot-shaped hand-held vibrator housing 3a, specifically on the housing base, which is between the slotted ones Segment receptacle 10 with inserted plastic segment 11, which is pivotally held in the segment receptacle 10 with side connectors 12, is screwed in as a handle bolt 13. In its pivoted position, the handle bolt 13 can be fixed in its pivoted position by further screwing in down to the base 14 of the segment receptacle 11.

Anstelle eines Edelstahlgehäuses kann auch ein Gehäuse aus elastischem Material wie Gummi oder Kunststoff treten, welches auch einstückig mit der Membrane gebildet sein kann.Instead of a stainless steel housing, a housing made of elastic material such as rubber or plastic can also be used, which can also be formed in one piece with the membrane.
