Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
219 words
An apparatus comprising: a radioaerosol generating source and support means for supporting the radioaerosol generating source; transport means including a passage providing a first inlet for communication with the surrounding atmosphere and an outlet adapted for connection to a patient, said transport means including a second inlet connected to said source for transporting the radioaerosol generated by said source to said outlet; and shielding means substantially surrounding said transport means for reducing the amount of radiation transmitted to the surrounding atmosphere, said shielding means including a first opening aligned with said first inlet for providing communication between said first inlet and the surrounding atmosphere during use of said apparatus and a second opening aligned with said outlet, said shielding means including a lower portion and a cover portion, said lower portion formed to define said support means and to substantially surround said support means and including means for supporting said transport means, said cover portion engaging said lower portion to enclose said transport means, said cover portion including latch means releasably attachable to said transport means for holding said cover portion in engagement with said transport means, said cover portion being removable with said transport means and said source from said source support means, said transport support means and said lower portion of said shielding means as a unit.

Claim 3
Dependent Claim
22 words
The apparatus of claim 1 wherein said transport means comprises a manifold, said latch means including first attachment means on said manifold.
Claim 4
Dependent Claim
24 words
The apparatus of claim 2 wherein said latch means includes second attachment means on said cover portion for releasably engaging said first attachment means.
Claim 5
Dependent Claim
81 words
The apparatus of claim 3 wherein said manifold is formed as a rigid unit and includes a first conduit and a second conduit joined at one end to form a first hollow connector end at the other and to form a second hollow connector, said first connector defining said outlet and said second connector defining said first inlet; and a third hollow connector located in said first conduit between said first and second connectors, said third connector defining said second inlet.
Claim 6
Dependent Claim
30 words
The apparatus of claim 4 wherein said first and second conduits define an opening between them and said first attachment means is formed on at least one of said conduits.
Claim 7
Dependent Claim
30 words
The apparatus of claim 5 wherein said second attachment means includes means formed to enter said opening between said first and second conduits and releasably engage said first attachment means.
Claim 8
Dependent Claim
21 words
The apparatus of claim 6 wherein said first attachment means includes lip means and said formed means engages said lip means.
Claim 9
Dependent Claim
85 words
The apparatus of claim 4 including 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 towards 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 towards said first connector and preventing fluid flow in the reverse direction.
