MEDICAL DEVICE AND METHOD FOR MANUFACTURING THE SAME
First Claim
1. An integrally-molded medical device, comprising:
- a tubular member; and
a fixing member molded to the tubular member and fixed to a first end of the tubular member,wherein the fixing member comprises an outer circumferential contact portion in contact with an outer circumferential face of the tubular member, and an inner circumferential contact portion in contact with an inner circumferential face of the tubular member, anda circumferential wall of the tubular member comprises, at different positions in a circumferential direction, a pinching portion which is pinched by and between the outer circumferential contact portion and the inner circumferential contact portion, and a non-pinching portion which is in contact with the outer circumferential contact portion, is not in contact with the inner circumferential contact portion, and is not pinched by the outer circumferential contact portion and the inner circumferential contact portion.

Abstract
An integrally-molded medical device is provided including a tubular member and a fixing member molded around and fixed to a first end of the tubular member. The fixing member is molded around the tubular member to include an outer circumferential contact portion in contact with an outer circumferential face of the tubular member, and to include an inner circumferential contact portion in contact with an inner circumferential face of the tubular member. The circumferential wall of the tubular member includes, at different positions in a circumferential direction, a pinching portion which is pinched by the outer circumferential contact portion and the inner circumferential contact portion, and a non-pinching portion which is in contact with the outer circumferential contact portion, is not in contact with the inner circumferential contact portion, and is not pinched by the outer circumferential contact portion and the inner circumferential contact portion.

14. A method for manufacturing an integrally-molded medical device which includes a tubular member and a fixing member fixed to a first end of the tubular member, the method comprising:
-
a loading step of loading the tubular member into a molding die including a cavity that forms an outer shape of the fixing member; a filling step of filling the molding die with a molding material of the fixing member so as to be in contact with an inner circumferential face and an outer circumferential face of the tubular member and integrally molding the fixing member and the tubular member together, wherein, after the molding material of the fixing member cures, the inner circumferential face and the outer circumferential face of the tubular member are pinched between portions of the fixing member at the first end of the tubular member. - View Dependent Claims (15, 16, 17)
