Abstract
Vakuumventil mit vertikaler Durchflussrichtung zum Öffnen der Luftzufuhr bei Klebehüllen, insbesondere bei medizinischen Klebepflastern für Wundversiegelung, dadurch gekennzeichnet, dass bei einem definierten Vakuum die Luftdurchlassöffnung (4) zur Belüftung der Wunde (13) in der Klebefolie (3) durch das Ventil (11), (7), (2) geschlossen ist, während sich bei Vakuumsteigerung das Ventil (11), (7), (2) öffnet und durch eine Luftdurchlassöffnung (4), Belüftungsbohrung (8) und Filter (2) Luft zur Belüftung der Wunde (13) gelangt.Vacuum valve with vertical flow direction for opening the air supply in adhesive casings, in particular for medical adhesive patches for wound sealing, characterized in that at a defined vacuum, the air passage opening (4) for venting the wound (13) in the adhesive film (3) through the valve (11) , (7), (2) is closed, while the vacuum (11), (7), (2) opens and through an air passage opening (4), ventilation hole (8) and filter (2) air for ventilation of Wound (13) passes.
Description
Die Erfindung betrifft eine klebende Wundabdeckung, die mit einem Vakuumventil, ausgebildet bei einem definierten Vakuum im Wundbereich, die notwendige Luftzufuhr im Wundbereich zur Absaugung von Wundsekret ermöglicht.The The invention relates to an adhesive wound cover which is provided with a vacuum valve, trained at a defined vacuum in the wound area, the necessary Air supply in the wound area for suction of wound secretion allows.
Wundauflagen werden seit Jahrzehnten für die Behandlung von Wunden angewendet. Meistens handelt es sich um flexible Pflaster, Binden, Wundauflagen aus Textilien oder Schaumstoffen, die steril an dem zu versorgenden Wundort am Körper des Patienten anliegen.dressings have been used for decades for the treatment of wounds. Mostly they are flexible patches, bandages, wound dressings made of textiles or foams that are sterile to be supplied Place the wound site on the body of the patient.

Das Reservoir kann somit entweder in der Kompresse oder zwischen der Kompresse und der Deckschicht liegen. Im Reservoir ist ein Wirkstoff enthalten, der in einer flüssigen oder pastösen Substanz gelöst ist. Das Material des Reservoirs ist für den Durchgang des Wirkstoffes und der Substanz, in der er gelöst ist, undurchlässig. Durch Fingerdruck wird das Reservoir zerstört und der Wirkstoff tränkt die Kompresse.The Reservoir can thus either in the compress or between the Compress and the top layer lie. In the reservoir is an active ingredient contained in a liquid or pasty Substance is dissolved. The material of the reservoir is for the passage of the active substance and the substance in which it is dissolved is impermeable. Finger pressure becomes the reservoir destroyed and the drug soaks the compress.

Zur Belüftung von Wundauflagen werden doppellumige Drains angewendet, die mit Hilfe einer mechanischen Steuerung die Luftzufuhr an die Wunde in einem Zeitintervall steuern, so dass der Vakuumprozess zur Absaugung von Wundsekret wieder aktiviert wird.to Ventilation of wound dressings are applied double-lumen drains, with the help of a mechanical control the air supply to the Control wound in a time interval, so that the vacuum process is activated again for the suction of wound exudate.
Der Nachteil der beschriebenen Wundauflagen besteht darin, dass ab einer Wundflächengröße von 6–7 cm die notwendige Luftzufuhr zur Aktivierung des Vakuumprozesses nicht ausreicht. Eine zusätzliche mechanische Luftzufuhr mit aufwendiger Konstruktion ist erforderlich.Of the Disadvantage of the wound dressings described is that from a Wound area size of 6-7 cm the necessary air supply to activate the vacuum process not sufficient. An additional mechanical air supply with complicated construction is required.
Vorliegender Erfindung liegt die Aufgabe zugrunde, eine Wundauflage zur Behandlung von Oberflächenwunden mit Hilfe von Vakuum zu schaffen, die mit Hilfe eines Ventilmechanismus ohne Gerätschaften die notwendige Luftzufuhr bei einem definierten Vakuum an der Wunde ermöglicht und den Vakuumprozess zur Absaugung von Wundsekret nicht behindert.present Invention is based on the object, a wound dressing for treatment to create surface wounds with the help of vacuum, which by means of a valve mechanism without equipment the necessary air supply at a defined vacuum at the wound does not allow and the vacuum process for the suction of wound secretion with special needs.
