Open the CIPO recordAbstract From the Canadian patent
A combination is disclosed of a handle and a member that is either a phlebotomy device or a drug-injecting syringe. The handle removably attaches by a mating pivot pin and aperture disposed relative to the axis of the handle and the member to ensure that the unlatched configuration is geometrically different from the latched configuration. Latching is achieved by a hook member on one that engages a recessed groove on the other simply by pivoting the handle until its axis coincides with the axis of the member.

Why it's free to use
- Filed January 23, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 23, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 23, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
