ている。(Prior Art) Conventionally, as a means for fixing a catheter made of difficult or non-adhesive synthetic resin such as Teflon to a needle base in this type of indwelling catheter, a molding die is attached to one end of a catheter a as shown in FIG. Tsuba b that is heated and melted using
Is integrally formed with the catheter a, and the needle base c is formed by injecting the needle base material from the outside to the catheter a and the collar b.
It is known that the catheter a is externally fitted and fixed to the inner surface of the infusion passage d. However, in such a configuration, a heating molding apparatus is required to heat and melt the brim b at one end of the catheter a for integral molding, and the workability is poor. In the case of Teflon, the resin material is heated and melted at the melting temperature. In that case, heat deterioration may be induced to reduce the material strength, and in the case of polytetrafluoroethylene (PTFE), when the resin material is heated and melted to form the brim b, it is burnt black and molded. There is a problem that can not be done. As shown in FIG. 4, one end of the catheter a is expanded to form a trapezoidal base portion e, the catheter a is inserted into the distal end portion of the needle base f, and the base portion e of the catheter a is inserted into the cylinder of the needle base f. It is known that the inner surface of the attachment hole g and a stator h inserted and fixed to the attachment hole g are sandwiched and fixed.

定出来る。Further, since the brim (9) provided on the base portion (8) of the catheter (2) is laminated without adhering to each other, when the catheter (2) is pulled, the brim (9) is attached to the base portion (8) of the catheter (2). The laminated part of the provided collar (9) spreads and catches on the rear end (11a) part of the adhesive (11), that is, the needle base (1) like an anchor, and the catheter (2) does not fall out of the needle base (1). The catheter (2) can be securely inserted and fixed to the needle base (1).
第１図実施例ではカテーテル（２）の基部（８）に設け

テルを提供するの効果がある。(Effect of the invention) As described above, according to the present invention, since the base portion of the catheter is folded outward and the laminated brim is provided, it is necessary to perform heating and melting as in the conventional case to form the brim. It is possible to efficiently install the collar at the base of the catheter without using a heat molding device, and when the catheter is pulled, the collars provided at the base of the catheter are folded and the laminated portions are spread and anchored. Since the catheter does not fall off from the needle base as it is caught on the needle base like in the above, the needle base made of synthetic resin with good adhesion such as vinyl chloride is made of difficult or non-adhesive synthetic resin such as Teflon. It is effective to provide an indwelling catheter in which the base of the catheter can be securely inserted and fixed.
