The present invention is formed of one or more synthetic resin impregnated layers of longitudinal strips of fabric, one side covered with pads, the other side covered with water vapor permeable longitudinal and / or transverse elastic films or seat covers, and stored in a moisture proof package. And a synthetic rigid bandage for splinting and / or supporting a wounded or injured limb of a human or animal walker, comprising a curable core that is moldable in a ready-to-use state. It provides a synthetic rigid bandage, characterized in that separated from the resin impregnated layer by a spacer.

Description

Synthetic rigid bandage

Conventionally, there are a number of documents that disclose orthopedic splints or supports which in principle are mostly similar to those described in the introductory paragraph of Claim 1, in which the means and materials are the subject of the invention. Natural or synthetic textile substrates and often glass fibers are used primarily as starting materials and they are impregnated with curable synthetic resins and stored in film envelopes, which are mainly protected in the form of rolls against access to the curing medium.

Among the hardeners are in particular the following: a) UV or X-rays (US 3 656 475), b) thermal action, for example interacting with polyurethanes and photoinitiators; For example, an orthopedic bandage made of a thick fibrous material consisting of a thermoplastic composition containing 60 to 80% by weight of saturated linear polyester and 20 to 40% by weight of resin having a low crystal point and a softening temperature of about 45 ° C. (US 4 326 509), c) air humidity or moisture; For example, the textile gas is impregnated with a resin selected from the group of hydrocurable isocyanates, stored in a porous envelope and impregnated in water for curing (DE-PS 23 57 931), d) for wounded or injured limbs Semi-rigid, elastic supports are described in US Pat. No. 4,968,542 and are likewise cured by the reaction of a resin with a curing agent.

Various passive experiences have shown that, as a disadvantage in the storage of resin impregnated fabric gases, resins pass through or out of the cover after unpredictable storage times in conventional systems of the type described above with resin impregnated cores. Because of this, there is a risk of contact with the user's hand and the skin, since the user must use it without a corresponding protective device (globe). In addition, the product becomes unusable.

FIELD OF THE INVENTION The present invention relates to synthetic rigid bandages, in particular formed of at least one synthetic resin impregnated layer of longitudinal strips of fabric, one side being a pad, the other being water vapor permeable longitudinal and / or transverse elastic film or seat cover. Covered with a curable core, stored in a moisture-proof package, ready-to-use and ready-to-use, and synthesized for splinting and / or supporting a wounded or injured limb of a human or animal locomotion organ Relates to rigid bandages.

An object of the present invention is to provide a synthetic rigid bandage of the type described in the introduction of claim 1 so as to reliably prevent the resin from passing through the cover during storage of the resin impregnated fabric or nonwoven fabric, even during extended periods, using inexpensive low cost means. To improve.

In order to achieve the above object in the synthetic rigid bandages of the kind first described, the present invention provides a spacer between a film or sheet and a resin-impregnated core connected to the film as an outer layer by segmental water vapor permeable pressure-sensitive adhesive coating. It is suggested to introduce.

For example, by adhering hydrophobic breathable longitudinal and / or transverse elastic nonwovens, cotton, plastic foams, nonwoven plastics, water repellent fabrics, or fabrics to the inner wall of the cover film, adverse contact between the resin and the film is prevented and the resin Completely prevents spills and their adverse effects. The spacer is free of resin in the core layer, and the segmented pressure-sensitive adhesive coat between the spacer and the film does not degrade the water vapor permeability of the film, while bringing a comprehensive best practice that can be performed at a negligibly low cost. In addition, laminates formed in this way are elastic in the transverse direction so that rigid bandages can be used on parts of the body, such as arms or legs, without being folded or crimped, and are also dried in a suitable time.

Embodiments of the invention are described in the dependent claims.

One embodiment of the rigid bandage is that the longitudinal strip layer forming the core is impregnated with a polyurethane resin. This resin is particularly suitable for curing by air humidity or water.

One embodiment may employ a means wherein the nonwoven consists of 100% polyester fibers.

In addition, in the present invention, the nonwoven fabric layer forms a laminate with the cover film, and the laminate has elasticity in the longitudinal direction and has water vapor permeability.

Finally, in one embodiment, the hydrophobic synthetic cotton layer is 1-8 mm thick, preferably 1.5-5 mm, particularly preferably 2.5 mm thick.

The use of synthetic rigid bandages of the present invention is not cumbersome and saves time since the padding of simple rigid bandages is not necessary. It is easy to handle, does not require a glove, and the so-called plaster room is kept clean.

The width and length of the rigid bandage are selected according to the instructions and the required length is removed from the package.

The cut spot is carefully and immediately sealed to avoid hardening due to air humidity approach. To this end, the material ends are folded inwards a few centimeters and tightly sealed. The cut rigid bandage is then immersed in water adjusted to about 20-30 ° C. and then folded to press excess water. The pad is then drawn against the glass fiber cutting edge by stretching slightly. For use, the moldable material must be secured with an elastic bandage at its end, hand molded to a portion of the body that is subsequently supported, and then wait unmoved if possible until the rigid bandage is set within 3 to 5 minutes.

The present invention is inexpensive, inexpensive, and prevents unwanted contact between the resin and the film, so that outflow of the resin is prevented with its disadvantages. In this respect, the present invention achieves the best of the problems first raised.
