• the splint of the present invention is structured to bring the aluminum casing in a pouch form into direct contact with the support, therefore making it possible to solve conventional problems. Ultimately, problems related to the festering of the affected part and the discomfort of the patient can be completely solved. Furthermore, the setting time is uniform and the rapid application to the affected part is realized, thus increasing the convenience of a person who applies the splint. Mode for the Invention
• Dry non- woven fabric for a support 1 was prepared to have a weight of 500-1500 g/D and a thickness of 2-5 mm, using a needle punching process, which was a mechanical bonding process.
• a water-curable resin to be applied on the support 1 a polyurethane prepolymer having NC0% (weight ratio) of 10-15% was used.
• the support was composed of the non- woven fabric, as a main component thereof, and the water-curable resin at a ratio of 7:3.
• liquid paraffin 20-200 mm thick As such, liquid paraffin was selected from among liquid paraffin oils for cosmetics, available from Kukdong Oil & Chemicals Co. Ltd., Korea.
• the aluminum casing 2 comprised a combination of nylon, aluminum and low- density polyethylene, and had a thickness of 110 mm.
• Non-woven fabric for an outer surface layer 3a was prepared using hydrophobic polyester through a needle punching process.
• the outer surface layer composed of such non- woven fabric had a weight of 100 g/D.
• a mechanical bonding type non-woven fabric was prepared using hydrophobic polypropylene through a needle punching process.
• the skin-protecting layer composed of such non- woven fabric had a weight of 320 g/D.
• a support having a monolayer was compressed at a pressure of 5 kgf/D, coated with a predetermined amount of a water-curable resin to have a ratio of the non- woven fabric to the water-curable resin of 7:3, and then further coated with liquid paraffin 100 mm thick. Thereafter, an aluminum casing, having two layers, was subjected to heat adhesion so that the support was enveloped therein, after which the outer surface layer and the skin-protecting layer were attached thereto using double-sided tape, thereby completing a product.
• the outer surface layer was prepared using double raschel in network form
• the product of the invention was advantageous because water was brought into direct contact not with the skin-protecting layer 3b or the outer surface layer 3 a but with the support 1 to react with the support, and thus the inventive product did not affect the aging or the setting time.
• the product of the invention had low initial water content, and thus the drying time thereof was decreased, so that no water remained. Unlike conventional products having water added throughout them, in the product of the invention, water was supplied only to the support requiring water. Accordingly, a patient did not feel discomfort due to water, thereby preventing the affected part from festering.
• the present invention provides a splint for orthopedics and a method of manufacturing the same.
• the splint for orthopedics using a water-curable resin it is easy to introduce water. Further, no water is supplied to the portion of the splint that comes into contact with the skin of a patient, thus decreasing the time required to dry the splint.
• the splint of the invention is advantageous in that the affected part of the patient can be prevented from festering, and the discomfort of the patient can be completely eliminated.
