Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
99 words
A manifold having an interior chamber and a plurality of ports, including a first port for attachment to a tracheal tube and a second port for connection to a breathable gas source, means for cleaning said interior chamber of said manifold when in use for delivering PEEP to a patient and for maintaining positive end expiratory pressure while cleaning said interior chamber, said means for cleaning comprising at least one additional port sized for directly accessing and cleaning said interior chamber of said manifold with a cleaning device while said manifold is in use and connected to a patient.
Claim 2
Dependent Claim
99 words
A manifold having an interior chamber and a plurality of ports, including a first port for attachment to a tracheal tube and a second port for connection to a breathable gas source, means for cleaning said interior chamber of said manifold when in use for delivering PEEP to a patient and for maintaining positive end expiratory pressure while cleaning said interior chamber, said means for cleaning comprising at least one additional port sized for directly accessing and cleaning said interior chamber of said manifold with a cleaning device while said manifold is in use and connected to a patient.
Claim 3
Dependent Claim
41 words
The manifold according to claim 1, wherein said at least one additional port comprises at least two ports directly accessing said interior chamber of said manifold, said at least two ports being positioned at diametrically opposed locations around said interior chamber.
Claim 4
Dependent Claim
23 words
The manifold according to claim 2, wherein said at least two ports are smaller in diameter than anyone of said plurality of ports.
Claim 5
Dependent Claim
21 words
The manifold according to claim 2, wherein said at least two ports and said second port lie in a single plane.
Claim 6
Dependent Claim
34 words
The manifold according to claim 2, including at least two ports directly accessing said interior chamber of said manifold, said at least two ports being in angles position in relation to a manifold body.
Claim 7
Dependent Claim
22 words

The manifold according to claim 6, including two pairs of said at least two ports, said pairs being positioned at diametrically opposed locations around said interior chamber.
Claim 9
Dependent Claim
36 words
The manifold according to claim 2, including at least two ports directly accessing said interior chamber of said manifold, each of said at least two ports having dual lumens for access by two separate cleaning devices.
Claim 10
Dependent Claim
21 words
The manifold according to claim 8, said at least two ports being positioned at diametrically opposed locations around said interior chamber.
Claim 11
Dependent Claim
23 words
The manifold according to claim 8, wherein said at least two ports are smaller in diameter than anyone of said plurality of ports.
Claim 12
Dependent Claim
21 words
The manifold according to claim 8, wherein said at least two ports and said second port lie in a single plane.
Claim 13
Independent Claim
164 words
A method of cleaning a manifold having an interior chamber and a plurality of ports, including a first port for attachment to a tracheal tube, a second port for connection to a breathable gas source, a third port for attachment of accessory devices thereto, a fourth port for weaning a patient off the respiratory support system, and at least one additional port sized for directly accessing and cleaning the interior chamber with at least one cleaning device while maintaining Positive End Expiratory Pressure, the method comprising the steps of: a) connecting said manifold to a tracheal tube which is intubating a patient and a breathing gas source; b) ventilating the patient with PEEP; c) uncapping the at least one additional port while PEEP is being delivered to the patient; d) cleaning the interior chamber with the at least one cleaning device; and e) recapping the at least one additional port after completion of said cleaning step the method being performed without disturbing patient ventilation.
Claim 14
Independent Claim
164 words
A method of cleaning a manifold having an interior chamber and a plurality of ports, including a first port for attachment to a tracheal tube, a second port for connection to a breathable gas source, a third port for attachment of accessory devices thereto, a fourth port for weaning a patient off the respiratory support system, and at least one additional port sized for directly accessing and cleaning the interior chamber with at least one cleaning device while maintaining Positive End Expiratory Pressure, the method comprising the steps of: a) connecting said manifold to a tracheal tube which is intubating a patient and a breathing gas source; b) ventilating the patient with PEEP; c) uncapping the at least one additional port while PEEP is being delivered to the patient; d) cleaning the interior chamber with the at least one cleaning device; and e) recapping the at least one additional port after completion of said cleaning step the method being performed without disturbing patient ventilation.
Claim 15
Dependent Claim
29 words
