Title: Innovations by David R Marble
Introduction
David R Marble is an accomplished inventor based in Seattle, WA. He has made significant contributions to the field of medical technology, particularly in the area of pulse oximetry. With a total of 2 patents to his name, Marble's work focuses on improving the accuracy and sensitivity of arterial oxygen saturation measurements.
Latest Patents
One of Marble's latest patents is the "Conformal Pulse Oximetry Sensor and Monitor." This innovative device features an optoelectronic pulse oximetry sensor that physically conforms to a patient's body part, such as a finger. The design ensures a firm engagement between the sensor and the patient's body, utilizing a flexible substrate that adheres to the skin. The sensor includes a light source assembly for transilluminating the body part and a light detector assembly for measuring the transmitted light. This configuration allows for improved accuracy in measuring arterial oxygen saturation, especially in low perfusion conditions.
Another notable patent is the "System and Method for the Algebraic Derivation of Physiological Signals." This technique employs mathematical relations of detected light signals to derive a pulse oximetry signal. By using first and second light sources, the system transmits light through the patient's finger or reflects it off blood vessels. A light detector captures the light from each source, generating a measured intensity signal that includes both the true intensity and any noise. The data is then analyzed to determine the best estimate of oxygen saturation in the patient.
