Abstract
A multi-lumen breathing tube device providing for separate and bidirectional gas flow for expired and inspired gas during ventilation of a lung. Embodiments of the multi-lumen breathing tube include an improved laryngeal mask airway device and an improved endotracheal tube. The invention is compatible with a circle breathing circuit system used with many mechanical ventilators including those used in conjunction with anesthesia machines.
Claims17
A breathing device for separating inhalation air and exhalation air when inserted to or distal to the supraglottic region of a mammal, comprising:
- a. bidirectional airway tube comprising an inhalation lumen having a proximal end and a distal end, and a separate exhalation lumen having a proximal end and a distal end, and a length;
- b. an inhalation lumen extending from the proximal end to a most distal point of fresh gas flow at the distal end;
- c. an exhalation lumen extending from the proximal end to a distal end proximate to the most distal point of fresh gas flow;
- d. wherein said inhalation lumen and said exhalation lumen provide for a means to separate the inhalation air and the exhalation air substantially the length of said bidirectional airway tube.
A breathing tube connector, said breathing tube connector having a divider to direct fresh gas flow through the inhalation lumen of said breathing tube connector to the inhalation lumen of said bidirectional airway tube, and to direct expired gas through the exhalation lumen of said breathing tube connector to the exhalation lumen of said bidirectional airway tube.
An elbow connector for a breathing tube, said elbow connector having a divider to direct fresh gas flow through the inhalation lumen of said elbow connector to the inhalation lumen of said breathing tube connector, and to direct expired gas through the exhalation lumen of said elbow connector to the exhalation lumen of said breathing tube connector.
A Y-piece for a circle breathing circuit having a partial divider that accepts and interlocks with a complementary divider from an other connector, such that when interlocked said partial divider of said Y-piece and the divider from said other connector form a baffle that directs fresh gas flow through the inhalation lumen of said Y-piece to the inhalation lumen of said other connector, and directs expired gas to the exhalation lumen of said other connector to the exhalation lumen of said Y-piece.
An improved laryngeal mask airway device further comprising,
- a. bidirectional airway tube comprising an inhalation lumen having a proximal end and a distal end, and a separate exhalation lumen having a proximal end and a distal end, and a length;
- b. an inhalation lumen extending from the proximal end to a most distal point of fresh gas flow at the distal end;
- c. an exhalation lumen extending from the proximal end to a distal end proximate to the most distal point of fresh gas flow;
- d. wherein said inhalation lumen and said exhalation lumen provide for a means to separate the inhalation air and the exhalation air substantially the length of said bidirectional airway tube.
An improved endotracheal tube further comprising,
- a. bidirectional airway tube comprising an inhalation lumen having a proximal end and a distal end, and a separate exhalation lumen having a proximal end and a distal end, and a length;
- b. an inhalation lumen extending from the proximal end to a most distal point of fresh gas flow at the distal end;
- c. an exhalation lumen extending from the proximal end to a distal end proximate to the most distal point of fresh gas flow;
- d. wherein said inhalation lumen and said exhalation lumen provide for a means to separate the inhalation air and the exhalation air substantially the length of said bidirectional airway tube.
An improved laryngeal mask airway device further comprising, a laryngeal mask that further comprises temperature sensitive memory foam.
