Section: claims

1. A Ge-68/Ga-68 nuclide generator structure comprising first washing bottle containing sodium citrate solution, second washing bottle containing hydrogen chloride solution, an organic resin absorbing column connected with the first washing bottle, an inorganic resin absorbing column connected with the second washing bottle, a silica-gel cartridge connected with first pair of valves, of which one is connected to the second washing bottle and the other is connected to the organic resin absorbing column, respectively, and sodium citrate stock connected with second pair of valves, of which one is connected to the first washing bottle and the other is connected to the inorganic resin absorbin column, respectively, for producing two chemical forms of radioisotope solution Ga-68 gallium citrate and Ga-68 gallium chloride. 2. According to the structure of Ge-68/Ga-68 nuclide generator described in claim 1, the first washing bottle contains sodium citrate solution at 0.1M; the second washing bottle contains hydrochloric acid solution at 0.1M, wherein concentration of washing solution is determined by the type of washing solution. 3. According to the structure of Ge-68/Ga-68 nuclide generator described in claim 1, first washing device withdrawing the sodium citrate solution and passing through organic resin absorbing column to drain out the radioisotope solution of Ga-68 gallium citrate. 4. According to the structure of Ge-68/Ga-68 nuclide generator described in claim 3, the radioisotope solution of Ga-68 gallium citrate passing silica-gel cartridge through a valve of the first pair of valves and washed in second washing device with hydrochloric acid solution through the other valve of the first pair of valves to obtain the radioisotope solution of Ga-68 gallium chloride, wherein both of the first pair valves are open or closed simultaneously during operation process. 5. According to the structure of Ge-68/Ga-68 nuclide generator described in claim 4, the second washing device withdrawing the hydrochloric acid solution and passing inorganic resin absorbing column to drain out the radioisotope solution of Ga-68 gallium chloride. 6. According to the structure of Ge-68/Ga-68 nuclide generator described in claim 5, the radioisotope solution of Ga-68 gallium chloride passing the sodium citrate stock through a valve of the second pair of valves and mixing with the sodium citrate solution from the first washing bottle through the other valve of the second pair of valves to obtain the radioisotope solution of Ga-68 gallium citrate, wherein both of the second pair valves are open or closed simultaneously during operation process. 7. According to the structure of Ge-68/Ga-68 nuclide generator described in claim 1, the generated radioisotope solution refers to as Ga-68 gallium citrate solution or Ga-68 gallium chloride solution, which can react with chelating agent DotA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) to produce chelated radioisotope solution.
