Abstract From the Canadian patent

An autotransfusion bag is provided with semi-rigid side walls and flexible material interconnecting the side walls. The bag is provided with spreader arms which extend across the top of the bag and across the bottom of the bag engaging retainer elements mounted on the external face of the side walls. The spreader arms maintain the bag in an open position to permit the bag to be filled with blood. When the bag is filled, the spreader arms may be removed to permit the bag to collapse as the blood is being reinfused to the patient.

Why it's free to use

  • Filed July 6, 1990 and granted September 13, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 6, 2010.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 6, 2012.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
