Abstract
Abstract A tracheotomy tube comprises a first port for orienting outside the neck of a wearer, a second port for orienting within the trachea of the wearer, and a passageway connecting the first and second ports to permit the flow of gases from the first port to the second port on inhalation by the wearer and from the second port to the first port on exhalation by the wearer. The tracheotomy tube further comprises a third port oriented between the first and second ports, and a valve controlling flow through the third port. The valve opens to permit flow from the passageway through the third port.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
A tracheotomy tube comprising an inner surface and an outer surface, a first port for orienting outside the neck of a wearer, a second port for orienting within the trachea of the wearer, the inner surface defining a passageway connecting the first and second ports to permit the flow of gases from the first port to the second on inhalation by the wearer and from the second port to the first on exhalation by the wearer, a third port between the first and second ports, and a valve for controlling flow through the third port, the third port connecting the inner and outer surfaces to thereby permit exhaled gases to flow from said tube into the trachea.
Claim 2
Dependent Claim
117 words
A tracheotomy tube comprising an inner surface and an outer surface, a first port for orienting outside the neck of a wearer, a second port for orienting within the trachea of the wearer, the inner surface defining a passageway connecting the first and second ports to permit the flow of gases from the first port to the second on inhalation by the wearer and from the second port to the first on exhalation by the wearer, a third port between the first and second ports, and a valve for controlling flow through the third port, the third port connecting the inner and outer surfaces to thereby permit exhaled gases to flow from said tube into the trachea.
Claim 3
Dependent Claim
53 words
The tracheotomy tube of claim 1 further comprising an inflatable cuff between the second and third ports and second passageway for introducing an inflating fluid into the cuff in situ in the trachea of the wearer to impede the flow of fluids between the cuff and the trachea when the cuff is inflated.
Claim 4
Dependent Claim
18 words
The tracheotomy tube of claim 1 wherein the valve comprises a flexible membrane having a slit in it.
Claim 5
Dependent Claim
53 words
The tracheotomy tube of claim 3 further comprising an inflatable cuff between the second and third ports and second passageway for introducing an inflating fluid into the cuff in situ in the trachea of the wearer to impede the flow of fluids between the cuff and the trachea when the cuff is inflated.
Claim 6
Dependent Claim
