Problems solved by technology

The general processing procedure is to set up an additional shield to complete the required operation and processing in the additional shield, but such a processing procedure is not applicable for mobile equipment or devices, which increases the difficulty and complexity of the operation. There is also a risk of leakage or contamination of radionuclides

Embodiment 1

[0073] figure 1 It is a structural schematic diagram of a container for closed-type operation of radionuclides of the present invention, Figure 2-5 They are the top view, front view, A-A sectional view and left view of the container respectively. The container comprises a lower container 1, an upper container 2, a bottle body 3 containing radionuclides, a slidable movable part 4, a channel 5 provided in the movable part for the circulation of radionuclides, a puncture needle 6, and a circumferential limiter. Position piece 7, axial limit piece 8.

[0074] This container assembly is finished, and in storage or transportation process, puncture needle 6 does not pierce the bottle cap of bottle body 3, and this moment container state is as follows: Image 6 shown. The lower container 1 and the upper container 2 of the container are tightly connected by hoops or nuts, and the upper container and the movable part are tightly connected by a plurality of circumferential limiting p...

Embodiment 2

[0093] Compared with the embodiment, the difference is that the container cancels a plurality of circumferential stoppers 7 and axial stoppers 8, the movable part 4 is constructed as a fixed type, and a mobile platform 15 is arranged at the bottom of the bottle body 3. The front view, A-A sectional view, right view, and B-B sectional view of the container are as follows Figure 14-17 shown. The mobile platform 15 is driven upward by the external connecting rod of the container, and the bottle body 3 is pushed upward, so that the bottle cap sealing rubber plug of the bottle body 3 is pierced by the puncture needle 6 .

Abstract

The invention belongs to the technical field of nuclear medicine. The invention discloses a container and a method for closed operation of radionuclide. According to the container, an upper containerand a lower container are arranged, and a channel moving part and a puncture needle are arranged; relative axial movement can be generated through the puncture needle and a bottle body which is placedin the lower container and is filled with radionuclide; the puncture needle punctures a bottle cap of the bottle body, the radionuclide in the bottle body is sucked or recycled by inserting a drainage tube, the bottle body filled with the radionuclide does not need to be taken out during use, operation is convenient, and meanwhile the risk that the radionuclide in the bottle body leaks or is polluted is avoided.

Description

technical field [0001] The invention relates to the technical field of nuclear medicine, in particular to a container and method for closed operation of radionuclides. Background technique [0002] In nuclear medicine, radionuclides can be selectively combined with biological localization agents at the molecular level, injected into the blood of the human body, diffused therewith, and concentrated at certain specific locations. In this case, sites of selective accumulation of radionuclides are exposed to radiation for the purpose of diagnosis or treatment of disease. [0003] In the field of nuclear medicine and isotopes, various radionuclides are frequently used and handled, but direct handling of these radionuclides is difficult. Radionuclides with short half-lives may require complex separation procedures to isolate the radionuclide of interest from other materials to avoid additional radiation harm to patients or operators. The general processing procedure is to set up...
