Patent number: 7201168Abstract: A non-tracheal ventilation tube includes a multi-lumen tube shaft having a proximal end and a distal end, a proximal cuff and a distal cuff. The multi-lumen tube shaft is separated into a ventilation channel extending from a proximal ventilation opening to a distal ventilation opening, a suction channel extending from a proximal suction opening to a distal suction opening, and an inflation channel. The proximal cuff is attached to the tube shaft and is connected to the inflation channel for inflation and deflation. The distal cuff is attached to the tube shaft on the distal side of the proximal cuff and is connected to the inflation channel for inflation and deflation. The proximal suction opening and the proximal ventilation opening are located on the proximal side of the proximal cuff. The distal suction opening is located on the distal side of the distal cuff. The distal ventilation opening is located between the proximal cuff and the distal cuff.Type: GrantFiled: April 12, 2005Date of Patent: April 10, 2007Assignee: King Systems CorporationInventors: Thomas W.

Patent number: 7178521Abstract: A unilimb breathing circuit has a proximal end coupling member, a distal end coupling member, an expiratory tube extending between the proximal and distal end coupling members, and an inspiratory tube extending between the proximal and distal end coupling members. The expiratory tube is a corrugated expiratory tube that is expandable between a fully compressed rest position, and a fully expanded rest position, and has a plurality of intermediate rest positions. At the plurality of intermediate rest positions, the expiratory tube is capable of maintaining its rest length without the exertion of an external force. The inspiratory tube is a corrugated inspiratory tube having a length that is variable between a fully compressed rest position and a fully expanded rest position, and includes a plurality of intermediate rest positions between the fully expanded rest position and the fully compressed rest position.Type: GrantFiled: March 26, 2004Date of Patent: February 20, 2007Assignee: King Systems CorporationInventors: Kevin D.

Patent number: 6070581Abstract: A laryngeal airway device includes an air tube with proximal and distal ends, and a sealing member attached to the distal end of the air tube. The sealing member includes an anterior surface adapted to seat in the throat, against the hyoid bone, and to stretch the laryngeal inlet. A hole extends through the anterior surface and the sealing member and communicates through an air passage with the distal end of the air tube. When the sealing member is seated in the throat, the hole is contained within the rim of the stretched laryngeal inlet, with which the anterior surface forms a seal that surrounds the hole. Airway patency is thereby ensured.Type: GrantFiled: June 30, 1997Date of Patent: June 6, 2000Assignee: Augustine Medical, Inc.Inventors: Scott D. Augustine, Randall C. Arnold, Thomas W. McGrail

Patent number: 5937859Abstract: A laryngeal airway device includes an air tube with proximal and distal ends, and a padded sealing member attached to the distal end of the air tube. The sealing member is padded on its anterior surface and is adapted to seat in the throat, against the hyoid bone, and to stretch the laryngeal inlet. A hole extends through the anterior surface padding of the sealing member and communicates through an air passage with the distal end of the air tube. When the sealing member is seated in the throat, the hole is contained within the rim of the stretched laryngeal inlet, with which the padded surface forms a seal that surrounds the hole. Airway patency is thereby ensured.Type: GrantFiled: October 16, 1996Date of Patent: August 17, 1999Assignee: Augustine Medical, Inc.Inventors: Scott D. Augustine, Randall C. Arnold, Thomas W. McGrail
