Trusted by Canadians for 3 Generations
At BIOS Diagnostics™, we are proud of our legacy in blood pressure monitoring in
Canada. From the early 1930’s to 1987 we manufactured “Tycos” brand professional
blood pressure equipment for doctors and hospitals in Canada.
In the 1970’s we pioneered the first blood pressure devices for monitoring at home,
and in the 1980’s we introduced digital technology in Canada. We haven’t been
counting, but we know that millions of our home-use monitors have been used by
Canadians in the last 30 years.
All BIOS Diagnostics™ devices are developed in collaboration with physicians and
clinically tested to prove their measurement accuracy. For more information on clinical
tests and other BIOS medical products, visit our website at www.biosmedical.com.
