Open the CIPO recordAbstract From the Canadian patent
An infusion system (11) includes fluid-delivery components for delivering a fluid from a separate source (13) of the fluid into a patient, transducer components (51) for producing a signal related to the pressure of the fluid in the fluid-delivery components (17), and identification components responsive to the signal for identifying pressure artifacts characteristic of patient activity. Gravity-fed infusion may be employed as well as infusion with a flow control device (15), and identification may be accomplished with a microprocessor (59) for examining the waveform of the signal and identifying pressure artifacts characteristic of patient activity amidst pressure changes caused by …

Why it's free to use
- Filed June 20, 1990 and granted May 12, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 20, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 20, 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.
