Title: Innovations by Mark Stewart

Introduction

Mark Stewart is an accomplished inventor based in East Hanover, NJ (US). He holds a total of four patents, showcasing his contributions to the field of medical technology. His work primarily focuses on systems and methods that address airway obstruction and related health issues.

Latest Patents

One of his latest patents is titled "System, method and biomarkers for airway obstruction." This invention provides two biomarkers for obstructive apnea. The first biomarker determines the amplitude and timing of inspiratory efforts from a bioelectric signal. It compares the respiratory rate with a normal pre-detection rate, and the amplitude of the effort is compared with a normal amplitude. If a series of inspiratory efforts are above a normal amplitude and with increasing amplitude, but at a normal rate, obstructive apnea is likely present. The second biomarker assesses heart rate and respiratory rate. It establishes a normal lower threshold for heartbeat intervals, and if subthreshold events occur, a commencement time for each sequence of subthreshold events is compared for a respiratory rate-normalized window. If the number of subthreshold events exceeds a minimum for the window, obstructive apnea is likely present.

Another significant patent is the "Acute pulmonary pressurization device and method of use." This system and method provide relief of negative lung pressure during acute laryngospasm or upper airway obstruction. It includes a non-toxic gas cartridge capable of supplying between 0.5-5 liters of gas during a procedure, a valve adapted to commence and stop gas release, and a trans-cricothyroid cartilage inflation needle for acutely relieving the negative pressure in the chest. The needle may also be used to insert a guidewire to assist in endotracheal tube insertion.
