Abstract
The present invention relates to the field of radioactive substances and in particular to a method to facilitate handling of radioactive solutions. Provided by the present invention is a device that enables preparation of capsules filled with radioactivity. More particularly, the radioactivity is suitable for use in certain radiopharmaceutical procedures. The present invention provides improved accuracy and uniformity of patient doses. Furthermore, the potential for spills and needle stick injuries is reduced and the radiation burden is reduced.
Claims33
A system comprising:
- (i) a capsule holder having a lower end and an upper end wherein said capsule holder comprises a solid base positioned at said lower end, a solid body extending upwardly from said solid base, and a well extending downwardly within said solid body wherein said well opens at the upper end of said capsule holder and ends prior to said solid base and is configured to receive a lower half of a capsule, wherein said capsule holder is formed from a radiation-shielding material;
- and
- (ii) a shielded needle positioner having a lower end and an upper end wherein said shielded needle positioner comprises a solid body defining a bore extending substantially linearly and centrally therethrough, said bore comprising a lower section opening onto said lower end and configured to be fitted over and contain the solid body of said capsule holder, and an upper section opening onto said upper end and configured to receive an upper half of a capsule, wherein said shielded needle positioner is formed from a radiation-shielding material.
The system 9, wherein said securing means comprises a spring or a screw.
