Abstract:
1. A method of manufacturing an elongated medical body coated with a fluororesin comprising: applying the fluororesin to an outer surface of an elongated core member comprised of a metallic substrate to produce a coated elongated member possessing an outer surface of the fluororesin, the elongated core member being mounted to and vertically suspended from a mounting member; relatively moving the coated elongated member and a heating unit comprised of an infrared ray-emitting heat source that emits infrared rays, the infrared ray-emitting heat source being positioned in an interior of a housing; emitting infrared rays from the infrared ray-emitting heat source during relative movement of the heating unit and the coated elongated member; heating the coated elongated member by way of heat resulting from the infrared rays emitted by the infrared ray-emitting heat source; the coated elongated member being heated to fix the fluororesin to the elongated core member by applying a forced convection of hot air, generated by the infrared ray-emitting heat source, to the coated elongated member in a direction from an upper side of the coated elongated member toward a lower side of the coated elongated member or in a direction from the lower side of the coated elongated member toward the upper side of the coated elongated member, the forced convection of hot air being applied to the coated elongated member by operation of a fan positioned in the interior of the housing; the heating of the elongated member comprising moving the heat source in a vertical direction and parallel to the elongated member; the coated elongated member being heated to a temperature equal to or greater than a melting temperature of the fluororesin; and shielding the coated elongated member from direct radiation by the infrared rays during the heating by a barrier positioned between the infrared ray-emitting heat source and the coated elongated member.
