Cellulose Cyanoacrylate and Method of Employment
Cellulose cyanoacrylate is employed either to bond two surfaces or to duplicate the shape of a three-dimensional object. The method is carried out by applying a release material to the object to be duplicated, applying a sheet of cellulosic material formed of wood fibers onto the three dimensional object, then saturating the sheet of cellulosic material with a cyanoacrylate glue and permitting the saturated sheet to cure. The resulting product duplicates the shape of the object. Two surfaces may be bonded by placing a sheet of cellulosic material between the two surfaces and applying the cyanoacrylate glue to edges of the sheet until saturated and allowing it to cure. Paper toweling may favorably be employed as the cellulosic material. This material may also be employed in bone or tooth repair. A break or fracture in an article can be repaired by positioning a sheet of cellulosic material over the break, saturating it with cyanoacrylate glue, and holding the saturated sheet in place with a releasable film. Irritating fumes may be suppressed by covering the saturated cellulosic material with a release film.

Multi-component frame for use in an orthopedic device
A multi-component frame includes a first component made from a rigid structural material and a second component connected to at least an end portion the first component. The first component is constructed from a metal or metal alloy, and the second component is constructed from a material different from the first component. The first and second components form at least part of a length of the multi-component frame.
Orthopaedic splinting system
A composite material in the form of a linear structure having a width, a length and a thickness, the composite material having a first component formed by a polymer and a second component formed by a reinforcing material, wherein the first component is a thermoplastic polymer selected from the group of biodegradable polymers and mixtures thereof, and the second component is platy wood particles. The composite material being formable at a temperature of about 50 to 70 C. and being capable of being employed as a blank for an orthopedic splint.
NOVEL COMPOSITE MATERIALS COMPRISING A THERMOPLASTIC MATRIX POLYMER AND WOOD PARTICLES
The present invention concerns a novel low-temperature thermoplastic wood-biopolymer composite comprised of small wood particles and a polycaprolactone (PCL) homopolymer for use in medical procedures including orthopedic casting or splinting. The material is made from a thermoplastic composite that softens when heated to approximately 60 C., after which it can be formed directly on the patient. The composite then retains its shape as it cools down. The material is composed of epsilon caprolactone homopolymer reinforced with discontinuous short length wood particles.

The first component is constructed from a metal or metal alloy, and the second component is constructed from a material different from the first component. The first and second components form at least part of a length of the multi-component frame.
CURABLE IMMOBILIZING CAST DRESSING
The invention relates to a curable immobilisation dressing comprising a substrate element in form of a flexible sleeve made of knitted fabric with a meshed weave, and a curable element in form of a flexible sleeve made of knitted fabric with a meshed weave. soaked in a curable material, intended to be slid onto the substrate element. Both elements are made of synthetic yarn with hydrophobic properties. The curable material constitutes a hybrid mixture comprising: (a) at least one compound undergoing polymerisation and/or crosslinking upon exposure to light. (b) at least one photoinitiator. (c) at least one compound undergoing polymerisation and/or crosslinking upon exposure to water, and (d) at least one catalyst of the reaction of polymerisation and/or crosslinking of the compound (c) upon exposure to water.

Easily formed arm external fixing brace
An arm external fixing brace (10), characterized by a thickness (H) of an edge of a mesh panel (12) thereof being greater than a thickness (B) of a central location. Selectively, raw materials of the mesh panel (12) being, according to weight: 60-78% PCL; 20-38% EVA; 2-20% inorganic filler; a thickness of an edge of a large ventilation hole of the mesh panel (12) being less than a thickness between the centers of two adjacent large ventilation holes; multiple fastening substrates (300) being pre-embedded at adjacent horizontal edge locations of the mesh panel (12); two wings of a fastening substrate (300) being provided with side holes (305), two sides of a middle part of a fastening substrate (300) being provided with grooves (302, 303) having symmetrical structures, the middle part of a fastening substrate (300) being provided with a middle hole (304), and a non-return surface (301) being provided at two sides of a circumference of the middle hole (304) inside the grooves (302, 303); two sides of a thumb hole (15) of the mesh panel (12) being tapered surfaces having symmetrical structures. The arm external fixing brace has few components, but simultaneously can prevent adhesion during a molding process so as to facilitate removal from a mold, make clinical operation convenient, and be comfortable to wear, metrics which were previously in conflict with one another.
Ankle-foot orthosis and method for making the same
