Automatic radioisotope filling apparatus

An automatic radioisotope filling apparatus comprising:

• a radioisotope vial containing a radioisotope solution;
• a saline vial containing a physiological saline solution;
• a dilution vial into which a predetermined amount of the radioisotope solution and a predetermined amount of the physiological saline solution are provided to prepare a diluted radioisotope solution;
• a radiation detector for measuring the radioactive intensity of the solution in the dilution vial;
• a plurality of label vials containing a drug to be labeled;
• and
• withdraw and transfer means for withdrawing and transferring said solutions, wherein the diluted radioisotope solution preparation in the dilution vial is provided into each of the label vials containing said drug, prepared as a labeled drug, and wherein each label vial is provided with a predetermined amount of the diluted radioisotope solution and means for immediately subjecting a label vial to stirring before a next label vial is subjected to a same procedure.

An automatic radioisotope filling apparatus comprising:

• a radioisotope generator for milking a radioisotope to produce a radioisotope solution;
• a saline vial containing a physiological saline solution;
• a plurality of label vials containing a drug into which a predetermined amount of the radioisotope solution or the physiological saline solution is to be provided;
• a metering and transfer means for withdrawing and transferring a predetermined amount of the radioisotope solution from the radioisotope generator by suction;
• a dilution vial into which a predetermined amount of the radioisotope solution and a predetermined amount of the physiological saline solution are provided to prepare a diluted radioisotope solution;
• and
• a radiation detector for measuring radioactive intensity of the radioisotope solution transferred to the dilution vial,
• wherein specific radioactivity of the radioisotope solution transferred to the dilution vial is calculated based on volume of the radioisotope solution transferred to the dilution vial, the radioactive intensity of the radioisotope solution measured by the radiation detector, an amount of drug needed and a name of a nuclide.

An automatic radioisotope filling apparatus comprising:

• a radioisotope vial containing a radioisotope solution, or a radioisotope generator for milking a radioisotope to produce a radioisotope solution;
• a saline vial containing a physiological saline solution;
• a syringe for withdrawing a predetermined amount of the radioisotope solution or the physiological saline solution by suction;
• a dilution vial into which a measured amount of the radioisotope solution or a measured amount of the physiological saline solution is to be provided;
• a plurality of label vials containing a drug into which a predetermined amount of the radioisotope solution or a predetermined amount of the physiological saline solution is to be provided;
• and
• a tube connecting the syringe, the vials and the generator,
• wherein in discharging the solution remaining in the tube, an amount of air, at least equivalent to the internal volume of a discharging section of the tube, is sucked into the syringe and then the solution remaining in the tube is discharged using the air as a buffer material.
