Radioisotope generator

Abstract

The invention relates to a device for producing a fluid containing a radioactive constituent, the device comprising: a shielded chamber within which is located an isotope container housing a radioactive isotope, the shielded chamber including first and second fluid connections to opposing ends of the isotope container and a fluid conduit extending from each of the first and second fluid connections to a fluid inlet and a fluid outlet respectively characterised in that the fluid inlet comprises a single spike having a substantially circular cross-section, the spike being adapted to penetrate the rubber seal of a vial and the spike having two bores, the first bore extending from a first aperture adjacent the tip of the spike to a fluid connection with the fluid conduit and the second bore extending from a second, separate aperture in the spike to a filtering air inlet which including a polytetrafluoroethylene filteration disc.

Description

[0001] This application is a divisional application of the Chinese patent application CN02828718.5 with the same name filed on December 11, 2002. technical field [0002] The present invention relates to technetium-99m ( 99m Radioisotope generators for radioisotopes such as Tc). Background technique [0003] In nuclear medicine, the diagnosis and / or treatment of disease is one of the main applications of short-lived radioisotopes. It is estimated that in nuclear medicine, more than 90% of the diagnostic procedures performed each year worldwide use added 99m Tc tracer radiopharmaceuticals. Given the short half-life of radiopharmaceuticals, it is helpful for facilities to generate the appropriate radioisotopes on-site. Therefore, the use of portable hospital / clinic type has greatly increased over the years 99m Adoption of Tc generator. Portable radioisotope generators are used to obtain shorter-lived daughter radioisotopes that are the product of radioactive decay of lon...

Problems solved by technology

The dispensing device is inserted into the elastic stopper, which presents a problem: any rotational movement of the rinse container will cause the stopper to tear, which in turn allows the uncontrolled introduction of air into the system, destroying the sterile environment

[0010] While piercing devices employing a single staple with two channels are known, such as shown in US 4,211,588, such piercing devices generally limit their application to intravenous systems
