Description

Unterschenkelkunstbein mit eingebautem Luftpolster Die Erfindung betrifft :ein Unterschenkelkunstbein mit eingebautem Luftpolster und besteht darin, daß das Luftpolster an der Stelle des oberen Trichterrandes, welche dem Knieansatz gegenüberliegt, unter Freilassung des übrigen größeren Randteiles als einheitlicher Körper angebracht ist, aber in das Innere des Stumpftrichters in Form von zwei Luftkammern sich gabelt, welche das Schienbein von Druck und Reibung frei zu halten; vermögen. Die bekannten Luftpolster, die den größten Teil des Trichterrandes umfassen, haben den Nachteil, da13 durch sie der Blutlauf am Amputationsstumpf abgedrosselt wird und daß die in gleichmäßiger Stärke um den Trichter herumgeführte Polsterung an Schienbein und Kniekehle zuviel Druck und Reibung verursacht und dadurch das dauernde Tragen dieser Polster unmöglich macht.Artificial lower leg with built-in air cushion The invention relates to : an artificial lower leg with a built-in air cushion and consists in the fact that the Air cushion at the point of the upper edge of the funnel, which is opposite the knee, attached as a unitary body leaving the rest of the larger edge part free is, but bifurcates into the interior of the stump funnel in the form of two air chambers, which keep the shin free from pressure and friction; capital. The known Air cushions, which cover most of the funnel edge, have the disadvantage that through them the blood flow at the amputation stump is throttled and that the in padding on the shin and bone of uniform thickness around the funnel The hollow of the knee causes too much pressure and friction and consequently the constant wearing of it Makes upholstery impossible.

Durch den Erfindungsgegenstand werden obige Nachteile behoben.The above disadvantages are eliminated by the subject matter of the invention.

Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise m einer Ausführungsform dargestellt, und zwar zeigt Abb. F den vorderen Trichterteil von innen gesehen mit eingebautem Luftpolster und Abb. z -einen Langschnitt mit eingebautem Luftpolster.In the drawing, the subject matter of the invention is, for example, one Embodiment shown, namely Fig. F shows the front funnel part of Seen inside with built-in air cushion and Fig. z -a long section with built-in Air cushion.

Die neue Polsterung besteht aus einem. aufblasbaren Gummikissen a; welches nach unten in zwei Luftkammern b und c ausläuft.The new upholstery consists of one. inflatable rubber cushion a; which runs down into two air chambers b and c.

Zum Aufblasen des Luftkissens ist ein Luftventil vorgesehen. Das Luftpolster .erstreckt sich ungefähr zu einem Drittel des ganzen Trichterumfanges, so daß, :etwa zwei Drittel vom Polster frei bleiben, wodurch eine freie Zirkulation des Blutumlaufes im Amputationsstumpf bestehen bleibt.An air valve is provided for inflating the air cushion. The air cushion .extends about a third of the entire funnel circumference, so that,: about two thirds of the pad remain free, allowing free circulation of blood remains in the amputation stump.
