Description

The The invention relates to a Schnellwundverband, a Schnellwundpflaster or a compression bandage for the fast wound care. For example, it is a compression plaster, which quickly stops the bleeding by metered compression without to prevent the circulation in the tissue. It consists of one Compression elastic functional unit with wound dressing Uptake of wound secretions, e.g. Blood, for example, applied on one self-adhesive inelastic carrier.

By Manual compression is the compression-elastic wound dressing reversibly deformed. The inventive entity is glued to the wound and closes the wound delayed by the Decompression of the functional unit. Moreover, the wound is going on Protected against the penetration of dirt or germs.

• 1) Blutabnahmen
• 2) Venenkatheter/Braunülen
• 3) Implantatswunden
• 4) Kleine Wunden und Schnitte

First of all, some conceivable application areas are listed, which are explained in more detail below:

• 1) Blood samples
• 2) Venous catheter / Braunülen
• 3) implant wounds
• 4) Small wounds and cuts

In the following individual application areas are enumerated:
To stop bleeding after taking blood, the wound must be masked slightly compressively, so that the formation of "blue spots" is prevented. For this purpose, for example, a gauze swab is glued to a 7 × 7 cm large Fixomullzuschnitt. This unit is glued to the wound. To assist, the patient holds his "thumb" on the patch to aid in the slight compression.

Also in simple implant surgery, for example subcutaneous implantation from hormone sticks to Disease prevention is the puncture channel closed compressively. The bleeding is thereby satisfied and to protect the wound from the ingress of germs.

Become needles and hoses placed on the patient, one also manages several individual ones Components. For permanent fixation is usually a combination used from a gauze swab and an inelastic adhesive carrier.

In Emergency first aid for severely bleeding wounds is used also very compressive wrap bandages. The wrapping of these bandages is difficult for the inexperienced. The bandage should not be too tight or too loose.

In Venous therapy also requires pressure to surround the surrounding veins after the desolation single sick vessels or also relieve after surgical removal. This pressure will often achieved by elastic bandages around the treated areas be wound while doing the wound knit flat and firmly above the Fix the Vulnerus Ulcer. The metered pressure is supposed to be the circulation promote in the vessels and thus facilitates the work of the venous valves. To cause problems generally areas around joints of the musculoskeletal system. It is often not there possible the necessary Pressure while ensuring maximum freedom of movement.

above enumerated Applications have in common that these consist of two or more components be composed and the application sometimes time consuming and is impractical. Furthermore, the combination of several components Time but also experience needed around the associations create professionally.

Wundpflaster are already developed in all forms and conceivable variations and optimized. There are already some publications about the Use of e.g. reversible deformable materials in medicine. In surgery, e.g. In laparoscopy you can get the reversible Exploitation of a material exploit the openings and cavities to be completed in the meantime after the organ removal. By the deformable flexible property is possible through the smallest operation openings to introduce this material into the patient and remove it again (US Pat. No. 6,080,168). This will be close to the surgical field underlying tissues and separated from the type of operation. The inventive effect lies in the filling and supporting action of the compressive material during The surgery and the material can be done through small surgical openings be introduced.

at In another application, a compressible sponge is described in US Pat 6,162,960 used to wound fluids take. Such applications are particularly strong secreting wounds, e.g. needed for burn victims. This Sponge, however, does not have reversible and elastic properties as required by the invention.

Elastic bandages are also used in venous therapy. After surgical removal or obliteration of diseased vessels, an elastic bandage is wrapped around the diseased areas. By default, elastic bandages and compresses from various manufacturers are used. The compresses close and protect the operating area. Alternatively, so-called zinc glue dressings are created. These differ from elastic bandages only by the Addition of zinc oxide. An inventive development describes the use of an elastic bandage unilaterally equipped with a stretchable hydrocolloid US Patent 5,006,401. The elastic bandage causes the compression. The hydrocolloid layer adheres to the skin, thereby facilitating the attachment of the bandage and provides the wound optimally. By skillful winding the required compression is achieved by the elasticity of the bandage.

there It often comes to differently stressed lots of one Leg. It may also be too strong for compression lead the blood circulation. In strongly moving body parts, such as. in the squat, a winding is effective.

The Invention is intended to enable new product applications and the disadvantages mentioned cancel already described products.

Of the Wound dressing should seal the wound permanently and germ-free and The functional unit with the wound dressing is said to stop the bleeding breastfeeding light compression. The compression is dependent the material properties of the functional unit, dosed. So that "bruises" by too light Pressure but also circulatory disorders at can be prevented to strong pressure.

By the practical combination of two or more components becomes an already complete wound plaster for direct application to the patient provided.

• – ein Wundpflaster bereit zu stellen, bei dem nicht mehrere Komponenten für die Anwendung zusammengefügt werden muss.
• – das unter Verwendung von möglichst geringem Materialeinsatz den genannten Produktnutzen bietet.
• – das unter Verwendung von möglichst wenig Material kostengünstig herstellbar ist.
• – und mit minimalem Zeitaufwand am Patienten anwendbar ist.

Another object of the present invention is:

• - to provide a wound plaster that does not require the assembly of multiple components for the application.
• - Provides the product benefits mentioned using as little as possible use of materials.
• - Which is inexpensive to produce using as little material as possible.
• - And with minimal time on the patient is applicable.

These The object underlying the invention is achieved by the teaching of Hauptanspruches solved. Advantageous embodiments but also other types of applications are while in the dependent claims explained.

Accordingly, the invention a wound dressing preferably consisting of a wound swab for the absorption of wound secretions, from an elastically reversible deformable functional unit and a self-adhesive or non-self-adhesive carrier for fixation on the skin. The wound swab may also be omitted become.

Of the Wound swabs are used to take up wound secretions, e.g. Blood. He can be made of different materials. Mentioned are cotton wool, plastic fabric, Knitted fabrics, polyurethane foams or hydrogels with superabsorbents that stick to dry skin, but not on the wound.

This Wound swabs are applied directly to the wound. Conceivable are sterile as well as unsterile variants. This wound swab can also be left out e.g. if the function of wound secretion uptake is not necessary or is also taken over by the functional unit.

The reversibly deformable functional unit, e.g. made of polymer foam is connected to the wound swab either positively or adhesively. Conceivable are also any other joining techniques, such as Ultrasonic welding, stitching or Melt. Also conceivable are any three-dimensionally shaped functional units containing surfaces, e.g. those of the patient, can be adjusted. This will meet the specific needs of the body.

The The following properties of the functional unit become the reaction of the invention demanded and can achieved by any materials, materials or composite materials become. In the following we talk about materials in the sense of a generic term. A restriction to certain reference characteristics / properties can not and may not done because the physical properties depending on the application For example, emergency primary care or rapid-release patches can vary considerably.

Physical Properties:

• Ad1 delayed in time decompression
• Ad2 partly elastic properties
• Ad3 reversible / partially reversible deformable

According to the invention is thus a material that is elastic by manual compression and / or deform partially elastic and its deformation is delayed in time reversibly or partially reversible regresses, or simply to meet the requirements of metered compression becomes.

Exemplary production engineering Properties of the functional unit:

• Ad4 physical properties metrologically controllable
• Ad5 physical properties technically reproducible to produce
• Ad6 good processability, good handling
• Ad7 physical properties adjustable
• Ad8 cost-effective producible
• Ad9 ecological compatible
• Ad10 sterilizable

According to the invention is thus preferably to use a material that can be processed well, which reproducible, controllable, possibly sterile, possibly ecological compatible and cost-effective can be produced.

When Material example is a polyurethane foam mentioned that meets the requirements sufficiently corresponds to the invention. It is only to a material example, which should not be tempted as a limitation to to apply this material class. Rather, this is as evidence of To understand feasibility.

to Fixing the patch unit in the wound area of the patient helps one of a self-adhesive but not adhesive carrier material. This carrier fixes the functional unit with the wound swab at the site of action. Furthermore, it should be inelastic in at least one direction be so that he has the strength that is involved in the delayed decompression of the functional Unfolded unit, put in a light pressure on the wound can. As an example, here is a product called Fixomull called the just has these properties mentioned.
