Open the CIPO recordAbstract From the Canadian patent
An infusion pump has a housing (10) accommodating a pump finger mechanism (12). The pump finger mechanism (12) acts on a pump hose (13) fastened at holders (16 21) of the housing. The pump hose (13) is supported by a door (24). In order to guarantee a proper and positionally correct placement of the pump hose one of the holders (16) comprises two oblique pins. The associated transition piece (15) of the pump hose (13) has two holes (18) with the same inclination angle as the pins. The other transition piece (20) is of a different structure so that the transition pieces cannot be mixed up. A longitudinal color strip on the pump hose indicates any twisting of the hose.

Why it's free to use
- Filed June 19, 2003 and granted August 2, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 19, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 19, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
