Title: Innovations by Inventor Kelvin Bonnema
Introduction
Kelvin Bonnema is an accomplished inventor based in Brooklyn Park, MN (US). He has made significant contributions to the field of medical technology, particularly in the area of heparin determination systems. With a total of 3 patents to his name, Bonnema's work showcases his dedication to advancing healthcare solutions.
Latest Patents
One of his latest patents is a point of care heparin determination system. This invention describes methods and devices for determining heparin concentration in blood at the point of care. The system includes cartridges with protamine ion sensitive electrodes (ISEs) and reference electrodes, which automatically determine heparin concentration. Some systems add blood to a protamine bolus sufficient to bind all heparin, leaving excess protamine. The concentration of excess protamine can be determined by measuring the initial slope of the electrode potential rate of change and comparing it to known protamine concentration slope values. Additionally, some cartridges utilize an oscillating pressure source to move the blood-protamine mixture across the protamine ISE. The invention also includes the use of a second blood sample with heparin removed or degraded to create a blank reference sample. The protamine ISEs can consist of polyurethane polymer, DNNS ionophore, and NPOE plasticizer, with specific structural characteristics to enhance performance.
