US Patent:

6338343, Jan 15, 2002

Filed:

May 8, 2000

Appl. No.:

09/566652

Inventors:

Scott Douglas Augustine - Bloomington MN
Randall Charles Arnold - Minnetonka MN
Thomas Wayne McGrail - Chaska MN

Assignee:

Augustine Medical, Inc. - Eden Prairie MN

International Classification:

A61M 1600

US Classification:

12820715, 12820714

Abstract:

An airway device for sealing against the laryngeal opening includes an air tube with proximal and distal ends and a sealing member attached to the distal end. The sealing member has a distal portion with a pair of opposing lateral flanges for engaging the cricoid cartilage to laterally align the sealing member with respect to the laryngeal inlet. The sealing member has a compressible anterior surface that contacts and seals against the laryngeal inlet. A tubular extension of the distal end of the air tube projects through and beyond the compressible anterior surface. The sealing member has a pronounced sigmoid shape having a lower section which, together with the tubular extension, creates a hook that provides an end point for accurate cephalad-caudad depth placement of the sealing member against the rim of the laryngeal inlet.

International Classification:

A61M 1600

US Classification:

12820026, 12820714, 12820715

Abstract:

A laryngeal airway device for sealing against the laryngeal opening includes an air tube with proximal and distal ends and a sealing member attached to the distal end. The sealing member includes a coupler for coupling the device to an introducer. Complementing the laryngeal airway device is an introducer that includes a track for receiving the coupler of the laryngeal airway device and guiding the sealing member to a sealing position with respect to the laryngeal inlet. The introducer may include an epiglottic engager on a distal end to engage the epiglottis and retain it while the sealing member is being tracked to engagement with the laryngeal inlet.

International Classification:

A61M 1600

US Classification:

12820715, 12820026, 12820714

Abstract:

A laryngeal airway device for sealing against the laryngeal opening includes an air tube with proximal and distal ends and a sealing member attached to the distal end. The airway device includes a tubular extension or snout for delivering air directly into the laryngeal opening; the snout is tapered and âhoodedâ in a manner that facilitates effective positioning of the airway device. The sealing member includes a coupler for coupling the device to an introducer. Complementing the laryngeal airway device is an introducer that includes a track for receiving the coupler of the laryngeal airway device and guiding the sealing member to a sealing position with respect to the laryngeal inlet.

International Classification:

A62B 9/04
A61M 16/00

US Classification:

12820227, 12820718, 128911

Abstract:

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. The inspiratory tube is also capable of maintaining these intermediate rest positions without the exertion of an external force.

International Classification:

A61M 16/00

US Classification:

12820714, 12820026

Abstract:

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.

US Classification:

12820711, 12820621, 12820628, 12820627

Abstract:

A strap system is useable with an anesthesia/respiratory face mask having an axially extending gas port connector and a gasket member. The gas port connector has a first diameter, and the gasket member is engageable with and conformable to a face of a patient. The strap system includes a strap member having a first end portion, a second end portion and a middle portion, and a collar. The collar includes an axially extending portion having a second diameter. The strap system includes a strap having a first end portion, and a second end portion; the collar also includes a radially extending portion having at least a first and a second slot through which the first and second end portions, respectively of the strap can pass. The slots are sized for adjustably receiving and fixedly positioning the first and second end portions of the strap.
