Title:
CATHETER
Document Type and Number:
WIPO Patent Application WO/2021/177434
Kind Code:
A1
Abstract:
When a contrast medium is injected under high pressure or a catheter shaft inserted into a body is pulled out of the body, the present invention reduces the risk of the shaft slipping out of a proximal hub. In a shaft accommodating part (22) of a hub (20), said shaft accommodating part (22) being for accommodating a shaft base end and base end vicinity, a shaft (10) is directly welded to the hub (20), and one of the welded surfaces (40) serves as the portion of the shaft accommodating part (22) having the smallest inner diameter. With this configuration, the shaft (10) can be prevented from slipping out of the hub (20) and, at the same time, worker safety can be ensured and manufacturing yield can be improved without using an adhesive, thus reducing both manufacturing costs and safety costs.
