Description
Elektrisches Heizkissen Ein elektrisches Heizkissen handelsüblicher Größe eignet sich ausschließlich für die Wärmebehandlung größerer Körperoberflächen, ist jedoch für die Wärmebehandlung kleiner Körperoberflächen, beispielsweise für die Wärmebehandlung des Auges, der Achsel-oder Kniehöhle, oder für die Wärmebeliandlung eines kleinen Geschwürs ungeeignet.Electric heating pad A commercially available electric heating pad Size is only suitable for heat treatment of larger body surfaces, however, is for the heat treatment of small body surfaces, for example for heat treatment of the eye, armpit or knee cavity, or for heat treatment a small ulcer unsuitable.
Durch die Erfindung wird dieser Übelstand beseitigt. Die Erfindung besteht darin, daß das Heizkissen mit Anschlußmitteln mechanischer und elektrischer Art ausgestattet ist, vermöge deren sich entsprechend ausgerüstete, eines selbständigen Zuleitungsanschlusses nicht bedürfende Ergänzungskissen an das Hauptkissen zwecks dessen Vergrößerung leicht anschließen lassen. Jeder Heizkissenteil hat mehrere Anschlußstellen. An den Ergänzungskissen sind elektrische Anschlußstellen zur Ermöglichung einer Parallelschaltung mit dem Hauptkissen eingerichtet.This drawback is eliminated by the invention. The invention consists in that the heating pad with connection means mechanical and electrical Art is equipped, by virtue of its appropriately equipped, an independent one Supply connection not required supplementary cushions to the main cushion for the purpose its enlargement can easily be connected. Each heating pad part has several Connection points. There are electrical connection points on the supplementary cushions to enable this set up a parallel connection with the main cushion.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung dargestellt.An embodiment of the subject matter of the invention is shown in the drawing shown.
In der Abb. i ist derjenige Heizkissenteil dargestellt, der mit einer Netzanschlußleitung versehen ist, und Abb. z zeigt einen Ergänzungsteil zu dem Heizkissen gemäß Abb. i.In Fig. I that part of the heating pad is shown, which with a Mains connection cable is provided, and Fig. Z shows a supplementary part for the heating pad according to fig. i.
Das Hauptheizkissen nach Abb. i besteht aus einer Anordnung von Heizdrähten a, die in einer Stoffhülle b untergebracht sind. Der Anschluß dieses Heizkissens an das Netz erfolgt durch die Drähte c, und das Heizkissen ist durch eine Thermosicherung Th vor unzulässiger Temperaturerhöhung geschützt. An der Schmal- und an der Breitseite des Heizkissens gemäß Abb. r befinden sich je zwei Druckknopfmatrizen d, in welche die Druckknopfpatrizen e des Ergänzungsheizkissens gemäß Abb. a eingefügt werden können. Beim Zusammenfügen der Heizkissenteile gemäß den Abb. i und z werden die Heizwicklungen derselben zueinander parallel geschaltet. Damit wächst auch die Stromaufnahme des vergrößerten Heizkissens, was bei richtiger Bemessung der Widerstände der Heizkissen zulässig und auch erwünscht ist, da hierbei die Wärmeübergangsoberfläche erhöht wird. Die Sicherung in dem an das Netz anschließbaren Heizkissenteil muß bei einer bestimmten Temperatur ansprechen und nicht bei einer bestimmten Stromstärke,, da die Stromstärke von der Zahl der miteinander verbundenen Heizkissen abhängt. Beim Zusammenfügen kleiner Heizkissenteile reichen die Kontaktglieder d, e auch zu ihrer mechanischen Verbindung aus; handelt es sich jedoch um die Zusammenfügung größerer Heizkissenteile, so ist es angezeigt, überdies noch rein mechanische Verbindungsglieder, beispielsweise Druckknöpfe, anzuwenden.The main heating pad according to Fig. I consists of an arrangement of heating wires a, which are housed in a fabric cover b. The connection of this heating pad to the network takes place via the wires c, and the heating pad is protected from inadmissible temperature increases by a thermal fuse Th. On the narrow side and on the broad side of the heating pad as shown in Fig. R there are two push-button matrices d, into which the push-button matrices e of the supplementary heating pad as shown in Fig. A can be inserted. When joining the heating pad parts according to Figs. I and z, the heating coils of the same are connected in parallel to one another. This also increases the power consumption of the enlarged heating pad, which is permissible and also desirable if the resistances of the heating pads are correctly dimensioned, since this increases the heat transfer surface. The fuse in the heating pad part that can be connected to the mains must respond at a certain temperature and not at a certain current strength, since the current strength depends on the number of heating cushions connected to one another. When joining together small parts of the heating pad, the contact members d, e are also sufficient for their mechanical connection; However, if larger heating pad parts are to be joined together, it is also advisable to use purely mechanical connecting elements, for example push buttons.
