  • Publication number: 20220249790
    Abstract: 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.

  • Publication number: 20210386949
    Abstract: 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.

  • Patent number: 11135048
    Abstract: 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.

  • Patent number: 8529442
    Abstract: Video-based laryngoscopes having an external centrally located channel coursing from the handle to a curved blade configured to deliver an ETT to a trachea as visualized by a non-removable, or alternatively, a removable video camera and lighting unit located beneath the external channel. The channel laryngoscope may be made for single use in a patient and discarded, or be processed for re-use. Alternatively, the channel laryngoscope may have a removable video camera and lighting member located within an internal chamber that runs parallel with the external channel. In another embodiment a laryngoscope adapter may be detachably affixable to the channel laryngoscope equipped with the non-removable camera to provide a decontaminated or sterile surface to permit re-use of the channel laryngoscope without having to undergo washing or decontamination procedures.
