Open the CIPO recordAbstract From the Canadian patent
The present invention describes an automated blood culture apparatus having a bell-shaped hollow rotatable drum for holding a number of blood culture bottles. All bottles are interrogated by sensor stations located within the drum with the whole system having only one moving part, and no flexible electric or optic cables. Consequently the expected, reliability is high, and the production cost should be low. The apparatus also includes an "auto-unloading" and sorting mechanism for sorting final "negative" and "positive" bottles.

Why it's free to use
- Filed September 18, 1997 and granted January 18, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 18, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 18, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
