preparation example Construction

[0054]During the preparation or use of radiopharmaceuticals, in order to avoid radioactive leakage, raw materials or preparations containing radionuclides are usually stored in a closed liquid storage bottle in the form of a solution, such as a vial. Herein, the radionuclide solution is also referred to as radioactive liquid. Extracting the radioactive liquid from the airtight vial usually requires manually opening the plastic cap, aluminum cap, and rubber stopper, and then using other pipetting tools or equipment to extract the radioactive liquid in it. There are many risks and shortcomings in this operation: (1) Extremely high risk of radioactive contamination, for example, a small amount of high-concentration radioactive liquid may be stained inside the rubber stopper, causing radioactive contamination to operators, operating instruments and the production environment; (2) In the process of opening the aluminum cap rubber stopper, there is a risk of aluminum scraps contamin...

Abstract

The present invention provides a radioactive liquid extraction device and method and use thereof, the extraction device is configured to extract a radioactive liquid from a liquid storage bottle, the extraction device comprises: a base configured to place the liquid storage bottle containing the radioactive liquid; a movable bracket configured to be movable in a direction substantially perpendicular to the base station; the puncture needle tube is supported by the movable bracket and is configured to penetrate through the rubber plug of the liquid storage bottle; the high polymer material tube is configured to enter the puncture needle tube from the end, away from the base station, of the puncture needle tube and penetrate out of the end, close to the base station, of the puncture needle tube so as to enter the liquid storage bottle to extract the radioactive liquid.

Description

technical field [0001] The present invention relates to the technical field of medicine, in particular to extraction equipment and extraction method of radioactive liquid, and use thereof. Background technique [0002] Radiopharmaceuticals are radiolabeled compounds that can be safely used in the diagnosis or treatment of human diseases, including inorganic, organic, biologically active substances and biological products containing radionuclides, which selectively accumulate in tissues and organs through radionuclides. Or participate in physiological, biochemical and other metabolic processes to achieve the purpose of diagnosis or treatment. [0003] The production of radiopharmaceuticals is usually carried out in isolation systems with radiation protection. The radionuclide is transferred to the reactor and subjected to isotopic labeling reaction with chemical precursors to prepare radiolabeled compounds, that is, active ingredients of radiopharmaceuticals. In order to av...
