Abstract

PURPOSE:To integrally form an easily handleable rigid tip part and a tubular main body, which is easily connected to medical appliances, by a method wherein the flexible tubular main body, which is connected to the rigid tip part, is formed by contacting and heating thermoplastic plastisol in order to obtain a medical conduit such as a cannula. CONSTITUTION:A cylindrical mold 36 is filled to a rigid polyvinyl chloride cannula tip part 32, on which a collar part 15 and side holes 16 are made. The mold 36 consists of a portion 36a and a portion 36b. The tip part 32 is fitted to the low permeability magnetic material portion 36b, which is adjacent to the high permeability magnetic material portion 36a. The mold 36 is immersed in polyvinyl chloride plastisol 37 to a part of the rear end of the tip part 32 so as to be high frequency induction-heated with coils 39. The plastisol 37 at the region in contact with the high magnetic material portion 36a gels, resulting in forming a gelatinized layer 34. After the heat curing of the layer, the mold 36 is removed in order to obtain a cannula 31. The tip part 32 and tubular main body 33 are different from each other in hardness and flexibility and strongly fixed to each other.
