摘要:
This invention provides holding and supporting appliances used in the fields of orthopedics, rehabilitation and sports and support members thereof that are light in weight, thin, rigid and durable and breathe well, and, furthermore, support members made of plastics reinforced triaxially woven fabrics by impregnating with a resin. The support members according to this invention comprises a shell-like piece formed of plastics reinforced with triaxially woven fabrics. Preferably, the formed piece should have openings representing 5 to 33 percent of the overall area thereof, and a flexural rigidity of 10 to 1 x 10 4 kg·mm 2 per unit width and a basis weight (weight per unit area) of 50 to 1000 g/m 2 . Holding and supporting appliances are formed by using the support members described above.
摘要:
The present invention provides an article comprising a curable resin and a filler associated with the resin. The incorporation of fillers into the casting materials of the present invention adds substantially to the strength of the cured casting material as well as to the handling properties of the uncured casting tape or bandage. The incorporation of fillers into the casting materials of the present invention also imparts air and vapor porosity to the cured casting materials. If desired articles of the present invention may also incorporate fibers (either individually, bundled, or in the form of a light-weight scrim) to provide increased cohesiveness to the uncured article. Extremely moldable casting tapes are also provided which comprise a highly-filled composite material coated on a light-weight scrim. The casting tapes of this embodiment handle like traditional plaster of Paris casts yet cure to a weight-bearing cast in less than one hour.
摘要:
A kit of curable orthopedic casting/splinting materials (11) in a substantially hermetic heat sealed package (10). The package (10) is formed of laminate sheet material (20; 30) having a heat sealable inner layer (24; 34) and an outer layer (21, 22; 31, 32). A plurality of evenly-spaced fibers (25; 35) are provided between the inner layer (24; 34) and outer layer (21, 22; 31, 32) of the laminate sheet material (20; 30) to facilitate tearing the laminate sheet material (20; 30) in a predetermined direction. The evenly-spaced fibers (25; 35) define the predetermined direction for the desired tear path, and are arranged and sized so as to facilitate evenly winding the laminate sheet material into rolls before cutting and heat sealing to form packages (10) and to allow forming reliable heat seals containing the fibers (25; 35).
摘要:
Apparatus for cutting free the rectum of hogs to be slaughtered and comprising a tubular knife (6), which is rotatable around and displaceable along its longitudinal axis, and an inner holding and controlling means (5) adapted, while the axially displaceable knife (6) advances to make the cut, to centre the knife in relation to the anus of the animals, and, after the cut has been made, to hold the rectum, which has been cut free. To obtain a safe hold without using devices getting in touch with the interior of the gut or which necessitate the use of vacuum in the interior of the rotating knife, the holding and controlling means (5) comprises at least one movable hook (7), which by activating a drive means (8) connected with the hook (7) is adapted to be taken through the skin and out again in the area immediately adjacent to the anus of the animal. The holding and controlling means minimize the risk of visceral contents leaking from the anus during the cutting free and the subsequent removal of the rectum.
摘要:
Es wird ein orthopädisches Verbandmaterial offenbart, das ein textiles Flächengebilde enthält, welches mit einer Mischung aus einem Polyisocyanatprepolymeren und einer wirksamen antiklebrigmachenden Menge eines oder mehrerer hydrophiler Bisurethane beschichtet oder imprägniert ist. In einer bevorzugten Ausführungsform ist das hydrophile Bisurethan abgeleitet aus der Reaktion eines Polyethylenglykols mit einem Molekulargewicht von etwa 4000 und Methylen-4,4′-bis(phenylisocyanat) zur Bildung eines auf Isocyanat endenden Prepolymeren, welches dann mit Ethanol umgesetzt wird.
摘要:
Water hardenable splinting bandages comprising a flexible fabric carrying a water curable isocyanate terminated prepolymer and a catalyst therefor wherein the prepolymer is in admixture with an organic acid anhydride to inhibit premature setting of the bandage on storage, water curable isocyanate terminated prepolymers and water hardenable compositions for use in the bandages and methods for their preparation.
摘要:
A method of preparing a water curable resin-coated sheet useful as an orthopedic cast having a non-polar hydrophobic lubricant admixed with a resin prepolymer in the coating in order to provide low surface tack, which comprises mixing the lubricant and resin prepolymer briefly to form an unstable mixture and immediately applying the mixture to a substrate sheet of fiberglass or the like, the lubricant being present in an amount in excess of that which is miscible with the resin prepolymer.
