Title:
医療的適用のためのカニューレアセンブリおよび製造方法
Document Type and Number:
Japanese Patent JP2004525655
Kind Code:
A
Abstract:
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.
