Method and system for estimating physiological parameters of phonation

InactiveUS20140122063A1Low variabilityEasy to separateSpeech analysisLarynxClassification methods

The invention consists of a method and computing system for recording and analyzing the voice which allows a series of parameters of phonation to be calculated. These transmit relevant information regarding effects caused by organic disorders (which affect the physiology of the larynx) or neurological disorders (which affect the cerebral centers of speech). The classification methods are also considered an essential part of the invention which allow estimations of the existing dysfunction to be obtained and for the allocation of personality. The usefulness of the invention lies in the possibility of applying the dysfunction estimation in primary care service centers for patient screening to specialist care centers, simplifying examination protocols, saving costs and reducing waiting lists. This methodology can also be used for detecting the personality of a speaker by their voice, allowing access to installations or services.

Equine airway disorders

ActiveUS9352152B2Promote regenerationReduce degenerationElectroencephalographySpinal electrodesDiseaseAnesthesia

Airway disorders in a horse are relieved by electrical stimulation of the airway tissue. Particular disorders and techniques include electrical stimulation to relieve laryngeal hemiplegia. A pacemaker processor generates an electrical treatment signal to be applied to upper airway tissue of the horse for treating the upper airway disorder. One or more stimulation electrodes interfaces with the upper airway tissue for delivering the treatment signal to the upper airway tissue.

Dual blade laryngoscope with esophageal obturator

InactiveUS20050054903A1Aircraft componentsBronchoscopesLarynxMedicine

A dual bladed laryngoscope for quickly and easily intubating a patient. The invention has two blades pivotally hinged on one side while the opposing side is open allowing the laryngoscope to be easily removed after intubating a patient. The proximal end of the upper blade has a grip portion which can be moved closer to or farther away from the handle attached to the proximal end of the lower blade to open or close the distal ends of the lower and upper blades. The lower blade of the invention has a distal end adapted as an esophageal obturator for obstructing the esophagus. An arytenoid bumper to prevent the laryngoscope from penetrating too far into the esophagus is preferably secured to the distal end of the lower blade. The arytenoid bumper may have a ramp or wedge shape adapted to deflect an intubation tube through a patient's larynx and into the trachea. The upper blade optionally has a tongue guard adapted to hold the tongue outside of a channel formed by the lower blade, the tongue guard and the upper blade. A suction conduit is optionally built in or secured to either the lower blade or the upper blade for providing a tube for suctioning secretions or emesis. A suction break is located in the handle of the laryngoscope to allow a finger of the hand holding the laryngoscope to control the presence and intensity of suction.
