Als Verbandmaterial werden gewöhnlich Mullbinden und Watte aus Baumwolle oder Zellstoff verwendet. Während Mull in erster Linie als Wundverband zum Aufsaugen von Flüssigkeiten wie Blut oder Eiter dient, zeigt Watte nur geringe Saugkraft und wird vor allem wegen ihrer Polsterwirkung eingesetzt. Bei der EntzUndungsbekämpfung dienen Mull und Watte als Material für feuchte Umschläge. Unter Umschlagraaterial ist Material für Wickel, Packungen, Kompressen, Bandagen und dgl. zu verstehen. Hierzu wird die mit Flüssigkeiten, z.B. Wasser, Alkohol, Borwasser oder anderen, eine bestimmte heilende Wirkung ausübenden Lösungen, getränkte Mullbinde oder Watte auf den zu behandelnden Körperteil des Patienten gelegt und anschließend mit wasserdichter Folie abgedeckt.Gauze bandages and cotton wool are usually used as dressings Made of cotton or cellulose used. While Mull in primarily used as a wound dressing to absorb fluids such as blood or pus, cotton wool shows little Suction power and is mainly used because of its cushioning effect. Gauze and are used to combat inflammation Cotton as a material for damp envelopes. Cover material includes material for wraps, packs, compresses, To understand bandages and the like. This is done with liquids, e.g. water, alcohol, boron water or other solutions with a certain healing effect, soaked gauze bandages or cotton wool on the too treated body part of the patient and then covered with waterproof film.
Ausgehend vom Stand der Technik besteht die Aufgabe der Erfindung darin, ein Verband- und Umschlagmaterial vorzuschlagen, das gute Saugkraft und zugleich gute Polsterwirkung zeigt. Es muß ferner für feuchte Umschläge geeignet sein, wobei eine zusätzliche Abdeckung mit wasserdichter Folie nicht nötig ist.Based on the prior art, the object of the invention is to provide a bandage and wrapping material to propose that shows good absorbency and at the same time good cushioning effect. It must also be used for damp envelopes be suitable, an additional cover with waterproof film is not necessary.

Depending on its use, it can be flat or in a special way the body parts to be covered, e.g. in the form of a finger cot.
Zur Herstellung der porigen Formkörpers aus regenerierter Cellulose wird, wie bekannt, zunächst Zellstoff in Viskose übergeführt. In die Viskose werden gegebenenfalls Verstärkungsfasern, z.B. Baumwollfasern einer Länge von 12 bis 15 mm, und zur Porenbildung Salzkörner, insbesondereTo produce the porous molded body from regenerated cellulose, as is known, cellulose is first used in Viscose transferred. Reinforcing fibers, e.g. cotton fibers with a length of 12, are optionally added to the viscose up to 15 mm, and grains of salt, in particular, for pore formation Glaubersalzkristalle, gewünschter Korngröße eingearbeitet. Daraufhin wird die Masse beispielsweise auf ein endloses Trägerband aufgetragen und in der Hitze durch das Koagulationsmedium, z.B. durch ein Wasserbad von etwa 1000C, ausgefällt.

Anschließend wird die Viskose wie Üblichare preferably incorporated into the viscose during the production of the porous shaped body, e.g. by Kneading or stirring, with a minimum amount of about 3 percent by weight, based on the porous shaped body, is required. Then the viscose is as usual zur Koagulation gebracht.

Die Pulverteilchen können eine Größe von etwa ein Mikron bis zu ca. 2 mm,brought to coagulation. A proportion of more than 35 to 40 percent by weight is not necessary and leads in addition, a gradual deterioration in the strength of the porous molded body. The powder particles can have a size of about one micron up to about 2 mm, Fasern oder Fibride eine mittlere Länge von ca. 0,05 bis 15 mm aufweisen.

optischen Aufhellern ist fUr diesen Zweck nicht zulässig. Zur Verbesserung des TrUbungsgrades des wäßrigen Auszuges wird auf der Oberfläche des porigen Formkörpers ein Celluloseether vernetzt und mit einem hydrophillerend wirkenden Netzmittel versetzt.optical brighteners are not permitted for this purpose. To improve the degree of turbidity of the aqueous extract, a surface of the porous shaped body is applied Cellulose ether cross-linked and with a hydrophillic agent acting wetting agent added.
Bei der Anwendung fUr feuchte Umschläge wird der porige Teil des erfindungsgemäßen Verbandmaterials angefeuchtet und mit der zu behandelnden Körperpartie des Patienten in Kontakt gebracht; die Kunststoffolle gewährleistet, daßWhen used for moist envelopes, the porous Part of the dressing material according to the invention moistened and brought into contact with the part of the patient's body to be treated; the plastic roll ensures that die angrenzenden Kleidungsstücke, Bettzeug usw. nicht feucht werden, Ein weiterer Vorteil ist der, daß die aufgesaugte Flüssigkeit Über einen längeren Zeitraum einwirken kann, da der Verdunstung entgegengewirkt wird. Um einen Feuchtigkeitsaustritt auch an den Rändern desThe adjacent clothing, bedding, etc. do not get wet. Another advantage is that the The absorbed liquid can act over a longer period of time, as evaporation is counteracted. To prevent moisture from escaping also at the edges of the Verbandmaterials zu verhindern, ist die Fläche der Folie vorzugsweise größer als die zu bedeckende Oberfläche des porigen Formkörpers.Preventing dressing material is the area of the film preferably larger than the surface to be covered of the porous shaped body.
Sofern jedoch Wickel verabreicht werden sollen, bei denen eine allmähliche Verdampfung der aufgesaugtenHowever, if compresses are to be administered, at which a gradual evaporation of the absorbed Flüssigkeit aufgrund der Körperwärme des Patienten erfolgen soll, so ist die Folie des Verbandmaterials mikroporös und/oder perforiert, d.h. mit kleinen Poren versehen, die beispielsweise mechanisch oder auf chemischem Wege in bekannter Welse in die Folie eingebrachtFluid due to the patient's body heat should take place, so is the film of the dressing material microporous and / or perforated, i.e. provided with small pores which, for example, are mechanically or chemically introduced into the film in a known manner sind. Mikroporöse Folien sind bekannt; sie zeigen einen lederartigen Griff. Zum Befestigen des Verbandmaterials 1st es gegebenenfalls mit eine« oder mehrerern Verschlüssen versehen, z.B. mit Klettenverschluß, Selbstklebestreifen, Bindebändern und dgl.are. Microporous films are known; they show you leather-like handle. To fasten the bandage material, it is optionally provided with one or more fasteners, e.g. with Velcro fasteners, self-adhesive strips, binding tapes and the like.
