With a total of 7 patents to his name, Petersen's work has had a profound impact on healthcare innovations.
Latest Patents
One of his latest patents is focused on reducing centrifugal pump bearing wear through dynamic magnetic coupling. This invention involves a pump drive for an extracorporeal blood pumping system that includes an adjustable drive magnet. The pump drive can be coupled to a blood pump featuring a pump impeller. It utilizes a stepper motor to dynamically adjust the position of the drive magnet, which varies the distance between the drive magnet and an impeller magnet. This adjustment minimizes forces acting on the bearings of the pump impeller, enhancing the overall efficiency and longevity of the system.
Another significant patent by Petersen is the clot protection and detection algorithm for activated clotting time testing. This innovation detects blood clotting time based on viscosity changes in a test sample. It employs a ferromagnetic washer that is lifted and dropped in a test chamber. The algorithm improves the detection of weak clots, which are often missed due to high levels of heparin in blood samples. By adjusting the lifting mechanism over time, the algorithm ensures accurate detection of clots, thereby improving patient outcomes.
