Improved needle design and manufacturing method for medical applications |
摘要 |
The present invention is directed to a novel process for inserting a cannula, such as a hypodermic needle, into a hub member by roughening a first portion of the cannula while leaving a second portion substantially smooth such that the first portion forms an interference fit and the second portion a line-to-line fit with the hub bore. In the absence of an adhesive, the second portion is passed through the hub bore followed by the first portion. The first portion is forced into the hub bore to provide an adhesive-free interference fit that is capable of resisting puncturing forces during normal use. |
