Abstract
Abstract A tracheal tube for use in intubation of a trachea, and embodying a resilient, yieldable cuff for effecting an air seal between the tube and the trachea. The cuff contains a resilient member, such as a rubber sponge, which resiliently maintains the cuff in an expanded position away from the tube. The cuff may be contracted by means of a vacuum applied thereinto by a secondary tube mounted on the tracheal tube. The cuff in its normal expanded position within the trachea affords a good seal and at the same time prevents injury to the tracheal wall by virtue of its yieldable contact therewith.

Claims Analysis
Total Claims: 31
Claim 1
Independent Claim
174 words
A tracheal tube comprising a. an elOngated tube having an outer surface, proximal end and distal end, b. a cuff mounted on said elongated tube adjacent to said distal end and in spaced relation to said proximal end, c. said cuff comprising 1. a flexible tubular cover a. disposed on said elongated tube in surrounding relation thereto, and b. having its ends secured to said outer surface, and 2. a resilient body portion mounted in said cover, d. said body portion having 1. normally an expanded position, wherein it is effective to hold a portion of said cover outwardly away from said elongated tube, and 2. a collapsed position, wherein the outer surface thereof is disposed closer to said elongated tube than in said expanded position to thereby permit said portion of said cover to assume a position closer to said elongated tube, and e. means connected to said cuff for creating and releasing a vacuum in said cover to thereby cause said body portion to move toward said collapsed and expanded positions, respectively.
