Open the CIPO recordAbstract From the Canadian patent
A transparent capillary tube is held in a cassette-type container during blood drawing and blood testing procedures. The cassette protects the capillary tube against breakage; allows the placement of patient and blood sample testing information labels thereon; and allows technicians to draw and test blood samples without having tocome into direct contact with the capillary tube or the blood. Once the blood sample is drawn into the capillary tube, the cassette can be used in the performance of kinetic gravimetric blood cell counts.

Why it's free to use
- Filed November 18, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 18, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 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.
