  • Patent number: 8118759
    Abstract: The disclosure relates to a system for producing an orthopedic splint made of a cast material, wherein the system includes at least one thermoplastic cast material present as a flat material web and a template having a flat template body, wherein the cast material can be wound around the template body in a prescribed direction for generating a splint blank, and the splint blank can be activated in order to achieve deformability, particularly after cutting the cast material to length, and to a method for producing an orthopedic splint.

  • Patent number: 6358220
    Abstract: The invention relates to a thermoplastic casting material, especially a thermoplastic casting material for orthopedic and other medical applications for immobilization of extremities and/or joints, that comprise a first textile fabric, a thermoplastic polymer applied to the first textile fabric and at least one second textile fabric applied to this composite. Additionally, the invention relates to a method for the production of this thermoplastic casting material that comprises the following steps: a) application of a thermoplastic polymer on a first textile fabric and b) application of at least one second textile fabric on the first textile fabric from step a) provided with the thermoplastic polymer.

  • Patent number: 5156589
    Abstract: A cohesive bandage fabricated according to a method comprising the steps of providing at least one layer of woven fabric and applying a coating containing polybutylacryate ester and alkyphenyl polyethylene glycol ether to at least one fabric face is disclosed. In one embodiment, the coating is applied by an airless method microselectively in statistical distribution where the quantity of coating is controlled by pump pressure. Alternatively, an aqueous dispersion of polybutyl acrylate ester and carboxymethyl cellulose is microselectively and cohesively coated on both sides of the fabric by screen printing to produce a regular dot pattern on both faces of the fabric.

  • Patent number: 4984570
    Abstract: The textile fabric is used as a wound dressing in much the same way as dressing gauze with improved characteristics compared with the latter and comprises a central web portion of man-made fibers having a high surface tension, and on either side thereof web portions formed from absorbent, cellulosic yarns. The central web portion is connected by looping to the outer web portions so that after folding, a nonstick wound dressing is obtained in which the hydrophobic man-made fibers functioning as the wound covering, come to rest on the wound, while the folded layers of cellulosic fibers behind it, act as an absorbent layer.
