Description

Spulenfeldelektrode für Ho chfrequenztherapie Die Erfindung betrifft eine Spulenfeldelektrode für Hochfrequenztherapie in Form eines z. B. um das Behandlungsobj ekt wickelbaren oder zu einer auf das Rehandlungsobjekt auflegbaren Flachspule formbaren, biegsamen elektrischen Leiters mit elektrischen Anschlußklemmen an seinen beiden Enden. Coil field electrode for high frequency therapy The invention relates a coil field electrode for high frequency therapy in the form of a z. B. to the treatment object ectly windable or formable into a flat coil that can be placed on the object to be treated, flexible electrical conductor with electrical terminals on both of them End up.

Bei der Hochfrequenztherapie im Spulenfeld ist es im Hinblick auf die Erzielung einer hinreichenden Tiefenwirkung des magnetischen Hochfrequenzfeldes erwünscht, zwischen dem Spulenleiter und dem Behandlungsobjekt Abstandshalter vorzusehen, um zu vermeiden, daß die nahe der Oberfläche des Behandlungsobjektes liegenden Gewebeschichten in den Bereich der größten Feldliniendichte nahe der Oberfläche des Spulenleiters kommen. Zu diesem Zweck sollten die erwähnten elektrischen Leiter mit einer Schwammgummischicht überzogen sein, deren Dicke erheblich größer ist als die Leiterdicke. Solche bekannten Spulenfeldelektroden mit einer auf den biegsamen Leiter aufvulkanisierten dicken, als Abstandshalter dienenden Schwammgummischicht bedingen aber eine Sonderfertigung in Kabelfabriken, die wegen des gegenüber anderen Kabeln geringen Bedarfs unrentabel ist. Solche Spulenfeldelektroden sind daher nur in sehr geringer Anzahl in den Handel gekommen, was einer Durchsetzung der an sich medizinisch außerordentlich günstigen Spulenfeldbehandlung abträglich war. With high frequency therapy in the coil field it is with regard to the achievement of a sufficient depth effect of the magnetic high-frequency field it is desirable to provide spacers between the coil conductor and the object to be treated, in order to avoid the tissue layers lying close to the surface of the object to be treated in the area of the greatest field line density near the surface of the coil conductor come. For this purpose, the mentioned electrical conductors should be covered with a sponge rubber layer be coated, the thickness of which is significantly greater than the conductor thickness. Such well-known Coil field electrodes with a thick vulcanized onto the flexible conductor, However, the sponge rubber layer serving as a spacer requires a special production in cable factories, which are unprofitable because of the low demand compared to other cables is. Such coil field electrodes are therefore only commercially available in very small numbers come what an enforcement which in itself medically extraordinarily favorable Coil field treatment was detrimental.

Demgegenüber offenbart die Erfindung einen Weg, wie trotz der speziellen Anforderungen ein Kabel für die Spulenfeldbehandlung im Preis niedrig gehalten werden kann. Gemäß der Erfindung ist das Kabel mit dem dicken Abstandshalter aufgeteilt in zwei handelsübliche Teile, nämlich in ein normal isoliertes elektrisches Kabel und in einen darüberschiebbaren Schwammgummischlauch, wie er für andere als elektrische Zwecke von der Schwammgummiindustrie hergestellt wird. In contrast, the invention discloses a way, as in spite of the special Requirements for a cable for coil field treatment are kept low in price can. According to the invention, the cable with the thick spacer is divided in two commercially available parts, namely in a normally insulated electrical cable and in a sponge rubber tube that can be slipped over it, as it is for non-electric ones Purposes made by the sponge rubber industry.

Ein Ausführungsbeispiel der Erfindung wird nachstehend an Hand der Figur näher erläutert. An embodiment of the invention is described below with reference to the Figure explained in more detail.

Die Figur veranschaulicht ein in einer auf das Behandlungsobjekt auflegbaren bekannten Filztasche 1 mit dem Kern 2 untergebrachtes, zu einer Spule geformtes, handelsüblich isoliertes Kabel 3, an dessen Enden Stecker 4 angebracht sind, um die Spule lösbar mit dem Ausgang eines nicht dargestellten elektrischen Hochfrequenzapparates verbinden zu können. über das Kabel 3 ist als Abstandshalter zum Behandlungsobjekt ein biegsamer Schlauch 5 aus Moosgummi abstreifbar übergezogen. Zum bequemen Einlegen der Spule in die Filztasche hat diese, wie bekannt, durch Laschen 6 verschließbare Schlitze 7 und 8. The figure illustrates one in one on the object to be treated known felt bag 1 with the core 2 which can be placed onto a spool molded, commercially available insulated cable 3, at the ends of which plug 4 is attached are detachable to the coil with the output of an electrical, not shown To be able to connect high-frequency apparatus. over the cable 3 is as a spacer A flexible tube 5 made of foam rubber is pulled over the object to be treated. As is known, the felt pouch has through for easy insertion of the bobbin Tabs 6 lockable slots 7 and 8.

PATENTANSPRUCU Spulenfeldelektrode für Hochfrequenztherapie, bestehend aus einem biegsamen elektrischen Leiter mit elektrischen Anschlußklemmen an seinen beiden Enden sowie aus einer den Leiter zum Behandlungsobjekt hin abdeckenden, als Abstandshalter dienenden Schwammgummischicht, deren Dicke erheblich größer ist als die Leiterdicke, dadurch gekennzeichnet, daß die Schwammgummischicht in Form eines handelsüblichen Schwammgummischlauches und der biegsame elektrische Leiter in Form eines handelsüblichen, normal isolierten, in den Schwammgummischlauch einschiebbaren elektrischen Kabels benutzt ist. PATENTANSPRUCU coil field electrode for high frequency therapy, consisting made of a flexible electrical conductor with electrical terminals on its both ends as well as a covering the head to the treatment object, as Spacers serving sponge rubber layer, the thickness of which is considerably greater than the conductor thickness, characterized in that the sponge rubber layer is in the form of a commercial sponge rubber hose and the flexible electrical conductor in the form a commercially available, normally insulated that can be pushed into the sponge rubber hose electrical cable is used.
