An apparatus for measuring fluid flow rate and cardiac output comprises a support member (12, 32) having a distal end (14 34), a , proximal end (16, 36) and an outer wall (18 38). A first, temperature sensing means (20 44) is positioned on said outer wall (18 38) with a second temperature sensing means (22 46) positioned , on said outer wall (18 38) proximal to said first temperature sensing means (20, 44). Heating means (24 26, 48) is also, positioned on said outer wall (18 38) juxtaposed to said first, temperature sensing means (20 44). Thus, by energising the heating means (24, 26, 48) a temperature differential between the first and second temperature sensing means (20, 22 44, 46) is …

Why it's free to use
- Filed May 17, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 17, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 17, 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.
