She has made significant contributions to the field of blood component separation, holding 2 patents that showcase her innovative approach to medical technology. Her work focuses on improving the efficiency and effectiveness of blood processing methods.

Latest Patents

One of her latest patents is a "Method of separating blood components." This invention relates to a method and a blood bag system for the separation of blood components from whole blood. The blood is tapped into a blood bag, which is then centrifuged to form an upper layer containing blood plasma, a lower layer containing red blood cells, and an intermediate buffy coat layer. The method is characterized by the blood being tapped into a first blood bag with outlets both at the top and bottom. After centrifugation, the layer containing blood plasma is pressed out through the upper outlet, while the layer containing red blood cells is pressed out through the lower outlet, leaving substantially only the intermediate layer in the bag.

Another significant patent is a "Device for blood separation." This invention relates to a device for blood separation by squeezing out blood components from a blood bag. The device comprises a support surface and a pressure surface that is movable relative to the support surface. It is designed to compress a blood bag inserted between the pressure surface and the support surface. The pressure surface is arranged essentially in parallel with the support surface, and drive means are provided for its displacement. The device includes at least one sensing device that detects when a pre-selected blood component layer has reached a given level in the blood bag, activating means to shut off at least one of the outlet conduits.
