Title: Innovations of Charles L. Davis

Introduction

Charles L. Davis is an accomplished inventor based in Beaverton, OR (US). He holds a total of 7 patents that showcase his contributions to medical technology. His work primarily focuses on noninvasive methods for measuring various physiological parameters, particularly related to blood density and hematocrit.

Latest Patents

One of his latest patents is a noninvasive method of measuring blood density and hematocrit. This invention includes an apparatus for applying pressure around a segment of a subject's limb, which incorporates pressure sensing means and an array of impedance sensing devices. These devices are applied to the subject's skin to measure independent fluid volume. The method records measurements of blood pressure, blood pulse wave velocity, and limb segment impedance, which are processed to yield changes in arterial blood volume during pulse wave passage. The resulting data is then used to calculate blood density and hematocrit through a linear relationship between the two.

Another significant patent by Davis is a noninvasive method of measuring physiological parameters. This invention provides means for identifying blood pressure characteristics in various types of vessels within the circulatory system. By applying known pressure to a body region, blood volume is forced from the region in a step-wise manner. The electrical impedance of the body part is measured during this process, allowing for the determination of blood pressure for each vessel type. This method is innovative as it does not rely on oscillometric or pulsatile measurement techniques.
