Title: Innovations of Donald E. Stapf: A Pioneer in Heat Exchange Technology
Introduction
Donald E. Stapf, based in Minneapolis, MN, is a notable inventor with an impressive portfolio that includes 31 patents. His work primarily focuses on innovations that enhance technological efficiency in the medical field, particularly regarding heat exchangers in infusion units.
Latest Patents
One of Stapf's latest patents is a "Heat Exchanger for High Flow Rate Infusion." This invention features a laminar fluid flow path positioned between heating plates, designed to conduct heat through direct contact. It incorporates a bubble trap that collects air from the infusate exiting the flow path and includes an air vent that allows for venting unwanted air. Furthermore, a valve has been integrated to shut off the flow of infusate if air is detected in the bubble trap, enhancing safety and reliability.
Another significant patent, "High Flow Rate Infusion with Extraction Assist," outlines an infusion unit consisting of a heating unit featuring opposed heating plates. The heat exchanger in this design facilitates fluid flow under pressure, heating the infusate efficiently. When the flow is stopped or interrupted, any trapped infusate is displaced into a reservoir, significantly reducing friction and making it easier to extract the heat exchanger from the unit.
