An activity detection station

Abstract

The invention provides an activity detection station, which is used for the activity detection of radiopharmaceuticals in vials, and comprises an inner cylinder, an outer cylinder, a station spring, an activity meter and a shielding cover; the outer cylinder is sleeved on the inner cylinder The outer and the two can be slidably matched, and the inner tube and the outer tube are telescopically telescopic to accommodate the vials, which makes the taking and placing of the vials more convenient. A shielding cover covers the upper end of the inner cylinder for closing the opening to shield radiation, and it can be toggled to open. Both the inner cylinder and the outer cylinder have an inner core of a radiation shielding cylinder and are provided with a shielding cover, so as to avoid external radiation interference and have higher measurement accuracy.

Description

technical field [0001] The invention relates to the field of automatic dispensing systems, in particular, to a device for detecting activity during the preparation of radiopharmaceuticals, and more particularly to an activity detecting station. Background technique [0002] Current nuclear medicine diagnostic methods mostly use radioisotopes, such as technetium (Tc-99m), which has a short half-life and cannot be stored for a long time, and needs to be dispensed before use. At present, for the preparation of technetium reagents, the molybdenum (Mo-99)-technetium (Tc-99m) generator is usually washed with a salt solution, the fission technetium is dissolved in the salt solution, and then washed into a vial located in a lead barrel, After dilution, drug distribution, and mixing with other ligands, technetium reagents are obtained, which are used for nuclear medicine diagnosis. Since molybdenum and technetium are both radioactive elements, they will cause radiation to the human ...

Problems solved by technology

[0004] However, multiple activity tests are required during the preparation of radiopharmaceuticals. During the manual preparation process, an activity meter is required to measure the activity. This process requires manual removal of the vial and placing it on the activity meter for measurement. The radiopharmaceuticals in the bottle will decay due to time, resulting in inaccurate measurement values, and will cause certain radioactive pollution to humans and the environment

[0005] In addition, if the above detection links are also applied to the automatic dispensing process, the easiest way is to put the existing activity meter into the dispensing equipment for activity detection and data export, but the existing activity meter is very large , will directly lead to an increase in the volume of the dispensing equipment. The most important thing is that the existing activity meters are all imported products. Due to restrictions such as patents, the measurement data cannot be directly exported, and the existing activity meters cannot be applied to the dispensing equipment.
