Publication number: 20220249790Abstract: A ventilation catheter and airway management system is described to create conditions that tend to clear secretions during the normal conduct of ventilation by having an exclusive outflow channel and/or to use a programed cuff leak combined with PEEP to protect the airway. The secretion clearing endotracheal tube may include separate inflow and outflow paths as part of a double lumen, to facilitate breathing when placed in a patient. The double lumen portion intersecting to form a single lumen for protrusion into the intratracheal region allowing the new inspiratory fluid from the airway management system to flow into a patient and the used inspiratory fluid from the patient to flow back to the airway management system. A pharyngeal suction component removes fluid from the intratracheal region via periodic suctioning.Type: ApplicationFiled: December 29, 2021Publication date: August 11, 2022Inventor: John Allen Pacey

Publication number: 20210386949Abstract: A pulmonary secretion clearing airway structure and related airway management system is disclosed that has a double lumen portion which each lumen of the double lumen portion operably secured to an airway management system so that inspiratory fluid (air/oxygen mixtures, with or without added water vapor) is delivered to the distal end of the ventilation catheter through one of the two lumens and expired inspiratory fluid, pulmonary secretions, and pulmonary fluids are removed from the patient through the other lumen. The expiratory fluid pathway preferably includes a secretion collection system for removing the pulmonary secretions and the like from the pathway, thereby improving operation and safety of the system. The airway structure can be a ventilation catheter or a supraglottic airway system such as laryngeal mask and the like.Type: ApplicationFiled: March 8, 2021Publication date: December 16, 2021Inventor: John Allen Pacey

Patent number: 11135048Abstract: An urethral compression apparatus is defined by a semi-cylindrical fenestrated dorsal hood that is worn dorsally on the penis and which is interconnected with a strap to a urethral compressor that is oriented ventrally to apply compressive pressure on the urethra to prevent urine leakage. The dorsal hood and the urethral compressor apply distributed pressure that prevents compromised venous and arterial circulation but eliminate incontinence. The device may be worn continually and is easily removed to allow voiding, then reattached. The fenestration in the dorsal hood (or plural fenestrations as the case may be) allows distribution of pressure to avoid venous and arterial blood flow interruption. The dorsal hood partially encircles the penile shaft and the urethral compressor is oriented ventrally and applies the desired pressure to the soft ventral tissues and the urethra.Type: GrantFiled: June 16, 2017Date of Patent: October 5, 2021Assignee: Pacey Medtech Ltd.Inventor: John Allen Pacey
