Problems solved by technology

Although no information is provided about the structure of the generator, it is clear that a shield must be constructed around the ion exchange column, since it is essential that the channels in the shield be aligned precisely with the inlet and outlet of the ion exchange column

Embodiment Construction

[0021] will now be referred to by way of example only figure 1 Describing an embodiment of the invention, the figure shows a radioisotope generator having fluid connections to an ion exchange column according to the invention.

[0022] figure 1A radioisotope generator 1 is shown comprising an outer container 2, a top plate 3 which is hermetically fastened to the outer container 2, and a separate top cover 4 which is placed over the top plate 3 Fastened to the outer container 2. Inside the outer vessel 2 is provided a shielded inner vessel 5, which is preferably but not exclusively made of either lead or a depleted uranium core within a stainless steel shell, providing shielding against radiation. Shielded container 5 surrounds a tube 6 containing ion exchange column 7 . Molybdenum in the form of its radioactive isotope 99 Mo is adsorbed on the ion exchange column 7 . The tube 6 containing the ion exchange column has frangible rubber seals 8 and 9 at opposite ends 10 and 1...

Abstract

A device for producing a fluid containing a radioactive constituent, comprising a shielded chamber (5) with an opening for receiving an isotope container (6) housing a radioactive isotope (7); a chamber closure (18) adapted for cooperating with and closing the chamber opening; a first fluid port comprising a first hollow needle projecting into the shielded chamber from the chamber closure for fluid communication with the isotope container; a second fluid port comprising a second hollow needle projecting into the shielded chamber from the closed end of the chamber opposite the chamber closure for fluid communication with the isotope container; first and second compressible buffers (28, 29) mounted so as to surround at least partially the respective first and second hollow needles (12, 13), each buffer providing an outer surface for contact with opposed ends of the isotope container; and a spacer of a predetermined thickness associated with one or each of the first and second compressible buffers for determining the positioning of the isotope container within the shielded chamber.

Description

technical field [0001] The present invention relates to technetium-99m ( 99m Tc) is a commonly used type of radioisotope generator and relates to a method of constituting the radioisotope generator. Background technique [0002] The diagnosis and / or treatment of disease in nuclear medicine is one of the main applications of short-lived radioisotopes. It has been confirmed that in nuclear medicine more than 90% of the diagnoses performed each year worldwide use 99m Tc as labeled radiopharmaceutical. Because radiopharmaceuticals have short half-lives, it is helpful to have on-site equipment to generate suitable radioisotopes. Therefore, the ratio of portable hospital size / clinical size has increased substantially in recent years 99m Use of the Tc generator. A portable radioisotope generator is used to obtain a shorter-lived daughter radioisotope, which is the product of radioactive decay of the longer-lived parent radioisotope, which is usually adsorbed on the bed of an i...
