Patent ID: 6858187

Claim:
A device for preparing a radioactive water solution to be infused in a patient and which is adapted to be mounted detachably to a surrounding lead shield, the device comprising: a reaction chamber ( 13 ) within which radioactive water is capable of forming by catalytic reaction of hydrogen gas with radioactive oxygen-15 gas; a diffusion chamber ( 14 ) which allows the radioactive water to penetrate, but which prevents the penetration of gases; tubes ( 26 ) and valves ( 16 , 18 ) for directing a sterile saline solution to the diffusion chamber ( 14 ), and for directing the saline solution containing radioactive water out from the diffusion chamber; a measuring instrument ( 17 ) for measuring the radioactivity of the radioactive solution, and a frame ( 50 ) for commonly mounting at least the diffusion chamber ( 14 ), the tubes ( 26 ), the valves ( 16 , 18 ) and the radioactivity measuring instrument ( 17 ), to form a separate water module unit ( 30 ), which as one entity is capable of being detached from the lead shield ( 10 ) surrounding the device.
