Title: The Innovations of Vernon D. Heidner
Introduction
Vernon D. Heidner is a notable inventor based in Mound, Minnesota. He is recognized for his contributions to medical technology, particularly in the field of pulse oximetry. His innovative work has led to the development of a significant patent that enhances the accuracy of blood constituent measurements.
Latest Patents
Heidner holds a patent for a single channel pulse oximeter. This electronic apparatus is designed to sense the percentage of different blood constituents in arterial blood. The device utilizes light of multiple separate wavelengths, which is sequentially passed through a portion of the body. This process can occur through direct transmission or scattering, allowing the pulsatile blood flow to modulate the intensity of the light. A signal processing circuit operates in accordance with the Lambert-Beer Law to determine the percentage of various blood constituents from the fluctuations in the logarithm of light absorption. The innovation includes time-multiplexing the sampling of separate wavelengths through a common channel, eliminating the need for separate electronics for each monitored constituent. Additionally, the signal processing circuitry compensates for noise from ambient light or other stray sources, thereby improving overall accuracy.
