Definitions

  • This invention relates to patient airway management systems such as ventilation catheters, which are commonly known as endotracheal tubes, and supraglottic airway systems such as laryngeal masks and the like.
  • the traditional field of airway management includes a process of controlled ventilation that usually uses a mechanical ventilating machine to deliver a predetermined amount of inspiratory fluid, which is usually an air/oxygen gas mixture, with or without added water vapor, to the lungs of a patient on a predetermined cycle.
  • the ventilating machine cycles between delivering relatively high-pressure inspiratory fluid via a delivery system to the patient's lungs for a short time, and then reducing the pressure in the delivery system for a short time so that used inspiratory fluid within the patient's lungs is expelled.
  • the ventilating machine repeats this cycle of delivering new inspiratory fluid to and then expelling used inspiratory fluid from a patient's lungs, thereby ensuring proper oxygenation of a patient during times when they are unable to breath on their own.
  • airway management systems have evolved to permit oxygenation of a patient using oxygenated liquids and/or using a non-cyclic process involving a continuous flow of oxygenated liquids to a patient's lungs while simultaneously maintaining a continuous flow of used fluids from the patient's lungs.
  • An example of these types of systems can be found in U.S. Pat. No. 5,706,830 to Parker.
  • Patient airway management structures such as ventilation catheters and supraglottal-positioned airway structures are commonly used by both traditional and these more recent airway management systems to deliver inspiratory fluid to the patient's lungs.
  • Inspiratory fluid is usually delivered to these structures through a single tube, the internal cavity of which is often referred to as a lumen, that has an open distal end.
  • the distal end is inserted through a patient's mouth and in cases where the structure is a catheter, inserted into the patient's trachea so that the distal end is positioned well past the patient's vocal chords.
  • the opposite end of the endotracheal tube is operably connected to a ventilation machine. Accordingly, inspiratory fluid is provided directly to the lungs through the endotracheal tube and used fluid is removed from the patient's lungs through the same tube.
  • the endotracheal tube must have a reasonably small cross-section to permit easy insertion and positioning of the tube within a patient's trachea.
  • the cross-section must be large enough to allow a sufficient flow of oxygenated fluid therethrough.
  • each tube can have its own pneumatic cuff to allow isolation of particular lungs and/or bronchial tubes.
  • each tube operates much like a single lumen tube, by providing both inspiratory fluid to the lung and removing used inspiratory fluid from the lung.
  • a laryngeal mask usually has an inflatable mask and resilient tube that connects to the inspiratory fluid delivery system.
  • the mask is inserted in the patient's pharynx, forming a low pressure seal around the laryngeal inlet thereby permitting positive pressure ventilation.
  • Exemplar laryngeal mask structures can be found in U.S. Pat. No. 7,140,368 to Collins and U.S. Pat. No. 5,632,271 to Brain, the disclosures of which are hereby incorporated by reference.
  • the pulmonary secretion clearing airway management systems is a ventilation catheter has a double lumen portion with 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 used inspiratory 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.
  • a secretion collection system for removing the pulmonary secretions and the like from the pathway thereby improving operation and safety of the system.
  • the use inspiratory fluid within the system rather than releasing it to the environment, the release of potentially airborne infective material from a contagious patient, such as SARS and the like, can be minimized.
  • An improved cuff can also be used.
  • the cuff encircles the distal end of the ventilation catheter to form a substantially pneumatic seal within the trachea.
  • a small channel is formed along one side of the vent so as to allow a small leakage of air from the lungs of the patient during use to the ventilation catheter. This air leakage facilitates removal of secretions from within the patient's lungs without interfering with the ventilation catheter.
  • Alternative embodiments include incorporating the double lumen structure into a supraglottic-positioned airway structure such as a laryngeal mask or a transpharyngeal-positioned inspiratory fluid delivery tube with pharyngeal and esophageal inflatable cuffs positioned therealong.
