Description

Die Erfindung betrifft ein Kissen zur Verhinderung und Behandlung von Dekubitalgeschwüren.The invention relates to a pillow for the prevention and treatment of decubitus ulcers.

Bei bewegungsbehinderten Personen, die sich über längere Zeiten in im wesentlichen unveränderten Sitzstellungen oder Liegepositionen befinden, besteht die Gefahr, daß sich infolge mangelhafter Gewebsernährung durch Sitzen oder durch Liegen Dekubitalgeschwüre ausbilden können.In the case of people with movement disabilities who are in essentially unchanged sitting or lying positions over long periods of time, there is a risk that decubitus ulcers may develop as a result of inadequate tissue nutrition through sitting or lying down.

Aufgabe der Erfindung ist es daher, ein Kissen zu schaffen, das das Entstehen von Druckgeschwüren vermeidet und mit dem sich bereits vorhandene Druckgeschwüre behandeln lassen.The object of the invention is therefore to provide a pillow which avoids the development of pressure sores and with which existing pressure sores can be treated.

Zur Lösung dieser Aufgabe ist das erfindungsgemäße Kissen durch eine Platte gekennzeichnet, in der eine Magnetspule angeordnet ist und die durch eine mit dieser verbundene plattenförmige Schicht aus einem viskoelastischen Kunststoff abgedeckt ist.To achieve this object, the pillow according to the invention is characterized by a plate in which a magnetic coil is arranged and which is covered by a plate-shaped layer made of a viscoelastic plastic connected to it.

Die Erfindung geht von der überraschenden Erkenntnis aus, daß sich mit einer Magnetfeldtherapie chronisch-entzündliche und degenerativ-entzündliche Prozesse, Traumata, Sauerstoffmangelerscheinungen, Knochendefekte und ähnliche Schäden erfolgreich behandeln lassen. Bei dieser Magnetfeldtherapie werden wir zu behandelnden Körperteile einem pulsierenden Magnetfeld mit extrem geringer Frequenz im Bereich von 1 - 50 Hertz, vorzugsweise 8 Hertz, ausgesetzt. Dieses pulsierende Magnetfeld hat eine massageähnliche Wirkung, die sich überraschenderweise zur Prophylaxe und Therapie von Dekubitalgeschwüren bei bewegungsbehinderten Personen in lang andauernden Sitz- bzw. Liegepositionen mit gutem Erfolg anwenden läßt. Um diese Magnetfeldtherapie bei gefährdeten Personen und bei Personen mit Dekubitalgeschwüren anwenden zu können, weist das erfindungsgemäße Kissen eine die Magnetspule abdeckende plattenförmige Schicht aus einem viskoelastischen Kunststoff auf, die einen guten Druckausgleich herstellt und eine entspannte Stellung der zu behandelnden Person bzw. der zu behandelnden Körperteile schafft, in der das pulsierende Magnetfeld seine durchblutungsfördernde, den Stoffwechsel aktivierende und die Sauerstoffzufuhr fördernde Wirkung voll entfalten kann.The invention is based on the surprising finding that chronic-inflammatory and degenerative-inflammatory processes, trauma, oxygen deficiency symptoms, bone defects and similar damage can be successfully treated with a magnetic field therapy. In this magnetic field therapy, the body parts to be treated are exposed to a pulsating magnetic field with an extremely low frequency in the range of 1-50 Hertz, preferably 8 Hertz. This pulsating magnetic field has a massage-like effect, which, surprisingly, can be used with great success for the prophylaxis and therapy of decubitus ulcers in people with reduced mobility in long-lasting sitting or lying positions. In order to be able to use this magnetic field therapy for people at risk and for people with decubitus ulcers, the cushion according to the invention has a plate-shaped layer made of a visco-elastic plastic covering the magnetic coil, which creates a good pressure equalization and a relaxed position of the person to be treated or the body parts to be treated creates in which the pulsating magnetic field can fully develop its blood circulation-promoting, metabolism-activating and oxygen-promoting effects.

Zweckmäßigerweise besteht die Platte aus einer Bodenplatte aus hartem Kunststoff, die mit einer Schicht aus Schaumkunststoff verbunden ist, die mehrfach dicker als die Bodenplatte ist und in die die ringförmige Magnetspule mit zu der Bodenplatte rechtwinkeliger Mittelachse eingebettet ist.The plate expediently consists of a base plate made of hard plastic which is connected to a layer of foam plastic which is several times thicker than the base plate and in which the ring-shaped magnetic coil is embedded with a central axis perpendicular to the base plate.

Die Schicht aus visko-elastischem Kunststoff besteht in besonders vorteilhafter Weise aus einem Zweikomponenten-Silikon-Kunststoff, der weich-plastisch eingestellt und von einer Kunststofffolie eingefaßt ist. Die Schicht weist ein gutes elastisch-plastisches Verhalten auf und hat nach ihrer Entlastung das Bestreben, aufgrund der Kriech- und Relaxationseigenschaften in ihren unverformten Ausgangszustand zurückzukehren. Die Weichheit des Zweikomponenten-Silikonkautschuks wird so eingestellt, daß er eine ausreichende plastische Nachgiebigkeit besitzt, die eine ausreichende Seitenfestigkeit gewährt, ohne das Gefühl zu vermitteln, auf einer schwabbeligen Unterlage zu sitzen.The layer of visco-elastic plastic consists in a particularly advantageous manner of a two-component silicone plastic, which is soft-plastic and is surrounded by a plastic film. The layer has good elastic-plastic behavior and, after being relieved, strives to return to its undeformed initial state due to the creep and relaxation properties. The softness of the two-component silicone rubber is adjusted in such a way that it has sufficient plastic resilience which ensures sufficient lateral strength without giving the feeling of sitting on a wobbly surface.

Da ein weich eingestellter Zweikomponenten-Silikonkautschuk eine ölige Oberfläche besitzt, wird er zweckmäßigerweise von einer Polyurethanfolie eingefaßt, die eine griffige und gut anfaßbare Hülle schafft.Since a softly set two-component silicone rubber has an oily surface, it is expediently surrounded by a polyurethane film, which creates a non-slip and easy-to-grip cover.

Das Kissen selbst ist mit einem Anschluß für ein Kabel versehen, das zu einem Generator führt, der den das pulsierende Magnetfeld erzeugenden Strom liefert.The pillow itself is provided with a connection for a cable which leads to a generator which supplies the current which generates the pulsating magnetic field.

Das erfindungsgemäße Kissen wird in seinen Abmessungen dem jeweiligen Verwendungszweck angepaßt. Für Rollstuhlfahrer hat es die Form üblicher Sitzkissen. Der Rollstuhlfahrer kann zur Magnetfeldbehandlung selbst das Kissen an den Generator anschließen und damit mit der gewünschten Häufigkeit die Behandlung durchführen.The dimensions of the pillow according to the invention are adapted to the respective intended use. For wheelchair users, it takes the form of conventional seat cushions. The wheelchair user can connect the cushion to the generator for magnetic field treatment and thus carry out the treatment at the desired frequency.

Für bettlägerige Patienten kann das Kissen in eine entsprechende Ausgleichsmatratze eingebaut werden.For bedridden patients, the pillow can be installed in an appropriate balancing mattress.

Ein Ausführungsbeispiel des erfindungsgemäßen Kissens wird nachstehend anhand der Zeichnung näher erläutert, in deren einziger Figur ein Schnitt durch ein Kissen dargestellt ist.An embodiment of the pillow according to the invention is explained in more detail below with reference to the drawing, in the single figure of which a section through a pillow is shown.

Das Kissen besteht aus einer stützenden rechteckigen oder quadratischen Bodenplatte 6 aus einem ausreichend festen und zähen Kunststoff. Mit der Bodenplatte 6 ist eine Schicht 4 aus Schaumkunststoff, vorzugsweise Polyurethanschaum, verbunden, in die eine Ringspule 5 eingebettet ist. Diese Ringspule kann aus einem Kupferdraht mit einem Durchmesser von etwa einem Millimeter bestehen, der zu seiner Isolierung lackiert ist. Die Spule kann beispielsweise etwa 100 Windungen aufweisen. Die Enden der Spule sind mit einem Anschluß 1 für das Generatorkabel verbunden, der seitlich an dem Kissen angeordnet ist und aus einem üblichen Stecker bestehen kann.The pillow consists of a supporting rectangular or square base plate 6 made of a sufficiently strong and tough plastic. A layer 4 of foam plastic, preferably polyurethane foam, is connected to the base plate 6, in which a ring coil 5 is embedded. This ring coil can consist of a copper wire with a diameter of about one millimeter, which is coated for its insulation. For example, the coil may have about 100 turns. The ends of the coil are connected to a connector 1 for the generator cable, which is arranged on the side of the cushion and can consist of a conventional plug.

Mit der Kunststoffschaumschicht 4 ist die etwa gleichdicke Schicht aus Zweikomponenten-Silikonkautschuk 3 verbunden, die in eine Hülle aus Polyurethanfolie eingeschweißt ist. Die Verbindung kann durch eine Verklebung hergestellt werden. Das aus der Bodenplatte 6 und den plattenförmigen Schichten 3, 4 aufgebaute Kissen ist auf seiner Oberseite durch einen Bezugsstoff 2 mit gerippter Oberfläche versehen. Der Bezug faßt zweckmäßigerweise das Kissen vollständig ein und ist zum Wechseln mit seitlichen Reißverschlüssen versehen.The approximately equally thick layer of two-component silicone rubber 3 is bonded to the plastic foam layer 4 and is welded into a cover made of polyurethane film. The connection can be made by gluing. The pillow constructed from the base plate 6 and the plate-shaped layers 3, 4 is provided on its upper side by a cover fabric 2 with a ribbed surface. The cover expediently completely surrounds the pillow and is provided with side zippers for changing.
