Abstract
Abstract A manifold is described, for delivery of radioaerosol to a patient, having a pair of rigid conduits joined at one end to form a first connector and at the other end to form a second connector. A third connector is formed in the first conduit between the first and second connectors and a one way-valve is located between the first and third connector. A second one-way valve is located in the second conduit to permit exhalation by the patient.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
170 words
A manifold comprising a first, rigid, tubular conduit and a second, rigid, tubular conduit joined at one end to form a first tubular connector and at the other end to form a second tubular connector, said first and second conduits being spaced from each other to define an opening therebetween; a third tubular connector located in said first conduit between said first and second connectors; attachment means formed on at least one of said first and second conduits and associated with said opening to attach said manifold to a support means; a first, one-way valve located in said first conduit between said first connector and said third connector permitting fluid flow through said first conduit in a direction from said first connector toward said second connector and preventing fluid flow in the reverse direction; and a second, one-way valve located in said second conduit permitting fluid flow through said second conduit in a direction from said second connector toward said first connector and preventing fluid flow in the reverse direction.
Claim 2
Dependent Claim
170 words
A manifold comprising a first, rigid, tubular conduit and a second, rigid, tubular conduit joined at one end to form a first tubular connector and at the other end to form a second tubular connector, said first and second conduits being spaced from each other to define an opening therebetween; a third tubular connector located in said first conduit between said first and second connectors; attachment means formed on at least one of said first and second conduits and associated with said opening to attach said manifold to a support means; a first, one-way valve located in said first conduit between said first connector and said third connector permitting fluid flow through said first conduit in a direction from said first connector toward said second connector and preventing fluid flow in the reverse direction; and a second, one-way valve located in said second conduit permitting fluid flow through said second conduit in a direction from said second connector toward said first connector and preventing fluid flow in the reverse direction.
Claim 3
Dependent Claim
31 words
The manifold of claim 1 wherein said attachment means includes a lip formed on at least a portion of said one of said conduits and said lip extends into said opening.
Claim 4
Dependent Claim
22 words
The manifold of claim 2 wherein said third connector has means thereon for rigidly securing said third connector to a fluid source.
Claim 5
Dependent Claim
21 words
The manifold of claim 3 wherein said securement means is a groove formed on the outer circumference of said third connector.
