Abstract

A new material (A) for producing bandages comprises a stabilizing, insulating layer (2) of closed-cell, skin-compatible neoprene, covered on both sides by laminated (adhered) textile material layers (1,3), such that the internal, skin contacting layer (3) provides a skin-bandage interface allowing respiration and controlled abstraction of heat and perspiration.

Description

The The present invention relates to a material for the production of Bandages, in particular medical, sports and veterinary medical Bandages.

• – sie sollen Gelenke bzw. Muskelbereiche stabilisieren und unterstützen, wobei die direkte mechanische Wirkung durch Integration zusätzlicher Stabilisierungselemente (z.B. Schienen, Pelotten) verstärkt werden kann,
• – sie sollen wärmen und damit einerseits zur Erhöhung der Elastizität und Belastbarkeit von Muskeln, Sehnen und Bändern in Aktivphasen des Körpers beitragen, und andererseits durch indirekte Beeinflussung von Versorgungssystemen und Nervenstrukturen Schmerzen mindern, und so medikamentöse Behandlung reduzieren,
• – sie sollen durch gleichmäßige Kompression von Muskel- und Gelenkbereichen, auch in der Bewegung, über Rezeptoren und Propriozeptoren Bewegungsabläufe verbessern,
• – sie sollen durch Mikromassage die Durchblutung fördern, damit Stoffwechselvorgänge beschleunigen und so Therapie, Rehabilitation und Regeneration verkürzen,
• – sie sollen die Hautatmung nicht unterbinden und das durch höheres Temperaturniveau vermehrt anfallende Schwitzwasser von den sensiblen Bereichen dorthin abführen, wo die Verdunstungskälte nicht schadet,
• – die Bestandteile der Bandagen sollten physiologisch unbedenklich sein,
• – die Bandagen sollen langlebig, formstabil und leicht zu reinigen sein.

Bandages in the medical, veterinary and sports fields, both for therapy and for prophylaxis, must meet certain requirements:

• They should stabilize and support joints or muscle areas, whereby the direct mechanical effect can be enhanced by integration of additional stabilizing elements (eg rails, pads),
• They should warm and thus contribute to increasing the elasticity and resilience of muscles, tendons and ligaments in active phases of the body, and on the other hand to reduce pain by indirectly influencing supply systems and nerve structures, and thus reduce drug treatment,
• They are intended to improve motion sequences through uniform compression of muscle and joint areas, also during movement, via receptors and proprioceptors,
• - They should promote the circulation through micro-massage, thus accelerating metabolic processes and thus shorten therapy, rehabilitation and regeneration,
• - they should not prevent skin respiration and dissipate the increased condensation caused by higher temperature levels of the sensitive areas where the evaporation does not harm,
• - the components of the bandages should be physiologically harmless,
• - The bandages should be durable, dimensionally stable and easy to clean.

From textile or Wirk-bandages is known (eg investigation report of the Institute of Applied Ergonomics, Munich 1996) that they can meet only a part of these demands:
The condensation is absorbed by the bandage and transported to the outside, where it evaporates and leads to cooling. This can have serious side effects especially with long-term use.

Textile Bandages do not compress evenly and can through the different Stretching of the mesh fabric partially cut, thereby Thrombosis danger exists at the joints. Textile bandages are less dimensionally stable, lose their after a relatively short time their desired Effect, i. the lifetime is limited.

Bandage material made of driven (closed-cell) synthetic polymers (eg neoprene, a synthetic chlorinated rubber, or polyurethane) do not have these disadvantages:
they form a good insulating layer against temperature changes and water. The body heat is held in the areas covered by bandage material on the body, cold from the outside is prevented from penetrating to the skin surface. The condensation water can not evaporate through the bandage material and thus lead to "hypothermia" in sensitive areas (see investigation report mentioned above).

A Compression by the high polymer bandage material is more uniform than in textile bandages. An anatomical preforming is easier. The bandages are long-term dimensional stability. The lifetime is greater than in textile bandages.

The cited Benefits are particularly pronounced with closed-cell neoprene; this material is very elastic, flexible and durable, reasons why it's been around many years as a bandage material is used. Products from this Neoprene are easy to clean.

• – sein allergenes und zelltoxisches Potential aufgrund von Inhaltsstoffen (z.B. Weichmacher und anderen Additives), die aggressiv gegenüber der Haut und anderem Gewebe reagieren können (Untersuchungen der BSL BIOSERVICE Scientific Laboratories GmbH, Planegg, 2002 und 2004),
• – die Unfähigkeit, überschüssige Wärme und Schwitzwasser geregelt abzuführen und die Hautatmung zu gewährleisten,
• – sein meist intensiver unangenehmer Geruch.

Disadvantages of the hitherto conventional neoprene bandage material, which is produced without exception on the basis of neoprene, which was developed for industrial use:

• Its allergenic and cytotoxic potential due to ingredients (eg plasticizers and other additives) that can react aggressively to the skin and other tissues (examinations of BSL BIOSERVICE Scientific Laboratories GmbH, Planegg, 2002 and 2004),
• - the inability to remove excess heat and condensation in a controlled manner and to ensure skin respiration,
• - his mostly intense unpleasant smell.

to solution the above problem, eliminating the disadvantages of the commonly used Bandage material for Neoprene bandages, with the present invention, a bandage material with the Features proposed by claim 1.

preferred Further development of the bandage material according to the invention are in the subclaims specified.

The bandage material according to the invention is characterized by the combination of three layers bonded together, wherein the outer layer consists of a textile lamination of synthetic fibers, natural fibers or a mixture of the two. The middle layer is made of a temperature-and water-insulating polymeric (closed or open-cell) material, esp It is largely odor-neutral, with the inner skin layer lying on top of the skin made of a synthetic fiber, natural fiber or blend fabric from both and is designed as a loop fabric, with the elimination of a portion of the loops patterns arise with channels that produce a pumping effect between the skin and bandage during movement, which allows breathing (air circulation) and provides a controlled heat and perspiration removal.

The The present invention will now be described with reference to an embodiment explained in conjunction with two drawings. The drawings show

1 a longitudinal sectional view of the claimed material with its three bonded layers,

2 a plan view of the material that rests on the skin (inner lining of the bandage material).

1 shows in a longitudinal sectional view of the structure of the bandage material. The outer (upper) layer 1 is formed by a textile lamination of synthetic fibers, natural fibers or a mixture of the two.

The middle layer 2 consists of a driven (closed-cell) skin-friendly neoprene, which serves as a stabilizing and hydrophobic insulating material (against temperature and water). The neoprene contains no or does not give off substances that have skin, tissue or cell damage, it is largely odorless.

The layer on the skin (lower) 3 consists of a fabric of synthetic fibers, natural fibers or a mixture of both. It is designed as Schlingware, where by eliminating a portion of the loops on the skin-facing side pattern with channels.

2 shows such a pattern in plan view and leaves the channels 4 become clear, which create a pumping effect between the skin and the bandage during movement, which allows breathing (air circulation, see 1 ) and ensures a controlled heat and perspiration removal.

3 to 9 show further pattern structures with channels used for this purpose.
