Abstract
Lamellendichtung für Arm- und Beinprothesen zum halten eines Unterdrucks im Prothesenschaft in Kombination mit Liner- oder Stumpfstrumpfversorgungenlamellar seal for poor and prosthetic legs to maintain a negative pressure in the prosthesis stem in combination with liner or stump stockings
Description
Um einen Unterdruck bei einem Vakuumhaftschaft mit Liner im Prothesenschaft halten zu können wird entweder ein Liner mit einer fest aufgebrachten Dichtung verwendet (Seal-In, Firma Össur) oder bei Unterschenkelprothesen zusätzlich eine luftundurchlässige Kniekappe verwendet wenn der Seal-In Liner nicht zum Einsatz kommt. (z. B. Harmony System der Firma Otto Bock)Around a negative pressure in a vacuum adhesion with liner in the prosthesis stem will be able to hold either a liner with a fixed seal used (Seal-In, Össur company) or, in the case of lower leg prostheses, an additional air-impermeable knee cap used when the Seal-In Liner is not used. (eg Harmony system of Otto Bock)
Die Probleme bei Linern mit fest aufgebrachter Dichtung sind:
- • dass sie sich aufgrund der Materialverdickung an der aufgebrachten Stelle schwerer anziehen lassen
- • dass die aufgebrachte Höhe der Dichtung vom Hersteller fest vorgegeben ist und nicht variabel ist → bei langen Stümpfen bleibt wird nur ein kleiner Teil des Schaftes genutzt und bei zu kurzen Stümpfen ist eine Abdichtung nicht mehr möglich
- • dass der Dichtungsumfang an die Linergrößen gekoppelt ist → je nach Bindegewebsstatus und form des Stumpfes kommt es zur Faltenbildung der Dichtung
- • dass bei Defekt oder Verschleiß der Dichtung der gesamte Liner ausgetauscht werden muss
- • that they are harder to put on due to thickening of the material at the applied point
- • that the applied height of the seal is fixed by the manufacturer and is not variable → with long stumps only a small part of the shank is used and with too short stumps a sealing is no longer possible
- • that the seal circumference is linked to the liner sizes → depending on the connective tissue status and shape of the stump, the seal will wrinkle
- • If the seal becomes defective or worn, the entire liner must be replaced
Die Problematik bei der Verwendung von luftundurchlässigen Kniekappen ist, dass hier höher versorgt wird als eigentlich notwendig und die Kniebeweglichkeit eingeschränkt wird.The The problem with the use of airtight knee caps is that supplied here higher is considered necessary and the mobility of the knee is limited.
Versorgungen mit Stumpfstümpfen bei Vakuumhaftschäften sind zurzeit nicht möglich. Soweit der Stand der Technik.supplies with stump stumps in Vakuumhaftschäften are currently not possible. As far as the state of the art.
Die Erfindung der Lamellendichtung für Arm- und Beinprothesen zum halten eines Unterdrucks im Prothesenschaft in Kombination mit Liner- oder Stumpfstrumpf-Versorgungen löst die oben aufgeführten Probleme mit den im Schutzanspruch aufgeführten Merkmalen.The Invention of the lamellar seal for Arm and leg prostheses for holding a negative pressure in the prosthesis shaft in combination with liner or stump stocking solutions solves the problems listed above with those listed in the protection claim Features.
Mit der Erfindung wird ermöglicht das alle auf dem Markt befindlichen Liner, die nicht mit einer Dichtlippe versehen sind, für ein Vakuumhaftschaft umgerüstet werden können. Hierbei ist im Besonderen zu erwähnen, dass die hierfür verwendete Lamellendichtung nicht mit dem Liner fest verbunden wird. Der Techniker bestimmt am Patienten die optimale Höhe der Lamellendichtung und bringt zirkulär in angemessener Breite der festgestellten Höhe einen haftvermittelnden Untergrund auf, dessen Dicke 0,5 mm nicht überschreitet. Hierauf wird nun vom Anwender die Strumpfbandförmige Lamellendichtung mit geeignetem Umfang Positioniert. Unter Zuhilfenahme eines Anziehsprays zieht der Anwender in bekannter Technik die Prothese mit Vakuumhaftschaft an. Da die Lamellendichtung nicht fest mit dem Liner verbunden ist kann sie vom Anwender bei Bedarf jederzeit ausgetauscht werden.With The invention is made possible all the liners on the market that do not have a sealing lip are provided for converted a vacuum adhesion can be. It should be mentioned in particular that's for this used lamellar seal is not firmly connected to the liner. Of the Technician determines the optimum height of the lamellar seal and the patient brings circular a reasonable amount of the determined height an adhesion-promoting Substrate whose thickness does not exceed 0.5 mm. This will be now the garter-shaped lamellar seal with the user Appropriate scope Positioned. With the help of a dressing spray the user draws on the prosthesis with vacuum grip in a known technique. Since the lamellar seal is not firmly connected to the liner they can be exchanged by the user whenever necessary.
Diese Technik ermöglicht nun neben dem Umrüsten von Linern in derselben Art und Weise das Umrüsten von Stumpfstrümfen jeglicher Art zur Nutzung von Vakuumhaftschäften. Bei der Nutzung von Stumpfstrümpfen besteht zudem die Möglichkeit durch auseinanderscheiden des Strumpfes in Höhe der später zu positionierenden Dichtlippe, dort die selbige durch verkleben oder nähen ein zu bringen.These Technology allows now next to the conversion of liners in the same way the conversion of stumps of any kind Type of use of Vakuumhaftschäften. When using stocking stockings exists also the possibility through separating the stocking in the amount of the later to be positioned sealing lip, there to bring the same by gluing or sewing.
