Title: Innovations of David H Harris

Introduction

David H Harris is a notable inventor based in Ogden, Utah, with a significant contribution to the field of noninvasive medical technology. He holds a total of seven patents, showcasing his dedication to advancing healthcare solutions through innovative inventions.

Latest Patents

One of his latest patents is a system for noninvasive hematocrit monitoring. This system determines hematocrit levels transcutaneously and noninvasively. It includes a finger clip assembly and an earlobe clip assembly, each equipped with at least a pair of emitters and a photodiode. These components are aligned to enable operation in either a transmissive mode or a reflectance mode. The system utilizes at least two, and preferably three, predetermined wavelengths of light that are passed onto or through body tissues such as the finger, earlobe, or scalp. The extinction of each wavelength is detected, and mathematical manipulation of the detected values compensates for the effects of body tissue and fluid to determine the hematocrit value. Additionally, if a fourth wavelength of light is used, which is extinguished differently by oxyhemoglobin and reduced hemoglobin, the blood oxygen saturation value can be determined independently of hematocrit. This method is particularly useful in states of low blood pressure or low blood flow, as it does not require a pulse wave.
