A pre-slit injection site (436) includes a housing with an axial flow path (444) therethrough. A first end portion (438) has the form of a male Luer connector. The other end includes a pre-slit septum (442). The tapered exterior surface of the male Luer is substantially surrounded by a generally cylindrical gripping collar (446). The second end is provided on its outer surface with threads (452) and also with a radially-extending shoulder (454). These two distinct locking means allow connection with blunt cannula devices having either an interiorly threaded sleeve (476) or resilient gripping fingers (460).

Why it's free to use
- Filed March 16, 1990 and granted February 27, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 16, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 16, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
