| 摘要 |
A catheter is disclosed which includes a mechanical connection between the strain relief thereof and the hub. The strain relief operates both to secure the catheter tube to the hub and to provide strain relief for the catheter tube. The strain relief connection is assisted in gripping the catheter tube by intentional overstressing of the catheter hub during manufacture thereof to expand the hub wall and generate residual hoop stresses therein which assist in securing the catheter tube within the hub. |
