Abstract

PURPOSE: To obtain the smooth and airtight connection with an extension tube, by molding the cavity of the connection part of a multi-cavity catheter so as to match with the outer shape of the connection end of the extension tube using a core.
CONSTITUTION: A principal part 1a and an enlarged base part 1b enlarged in a taper shape for connecting an extension tube are continuously molded by extrusion molding and cut to obtain a catheter main body 1 having cavities 2aW2d. Cores 4 made of stainless steel each having an outer shape almost equal to that of each of extension tubes 3 to be connected and inserted in the cavities 2aW2d up to a necessary depth under pressure and the catheter main body 1 is partially introduced into a mold 5 to be heated by hot air. The catheter main body 1 is drawn in the mold 5 and a molding scheduled part 1a is heated to higher temp. to old the cavities 2eW2h having circular cross-sections matching with those of the cores 4 to the connection end part of the catheter main body 1. The extension tubes 3 coated with an adhesive are inserted in the molded cavities 2eW2h of the catheter main body 1 and the adhesive is cured to obtain the smooth and airtight connection of the catheter main body 1 and the extension tubes 3.
