Description

Technical Field

[0001] This utility model relates to the field of radionuclide technology, specifically to a parent radionuclide container. Background Technology

[0002] The parent nuclide is a nuclide that can decay into other nuclides in a radioactive decay chain.

[0003] In the existing technology, parent radionuclides play an important role in clinical diagnosis and treatment. Through the application of daughter radionuclides, they provide doctors with important diagnostic information. Because they are radioactive, they are often stored in containers with multiple protective layers.

[0004] However, while existing containers can store parent radionuclides without emitting radioactivity, when the parent radionuclides are extracted, the container top is opened, creating an opening through which the parent radionuclides can emanate radioactivity, potentially causing radioactive damage to operators.

[0026] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figures 1 to 8 This utility model provides a technical solution: a parent radionuclide container.

[0028] In Embodiment 1, a first storage groove 16 is provided on the inner wall of the upper opening of the first protective chamber 3. A first spring 11 is movably provided on the inner wall of the first storage groove 16. A first top cover 1 is movably provided on the inner wall of the upper opening of the first protective chamber 3. A first baffle 14 is fixed on the side surface of the first top cover 1. When the suction rod is no longer inserted into the first through hole 2, the first spring 11 will immediately push the first baffle 14 to rotate in the first storage groove 16, so that the first through hole 2 no longer corresponds to the second through hole 6.

[0029] The upper opening of the second protective chamber 4 has a second storage groove 22 on its inner wall. A second spring 18 is movably installed on the inner wall of the second storage groove 22. When the suction rod is no longer inserted into the second through hole 6, the second spring 18 will immediately push the second baffle 19 to rotate in the second storage groove 22, so that the second through hole 6 no longer corresponds to the third through hole 10. The upper opening of the second protective chamber 4 has a second top cover 8 movably installed on its inner wall. The second baffle 19 is fixed on the side surface of the second top cover 8. A container 5 is fixed inside the second protective chamber 4. A third top cover 9 is fixed on the upper end of the container 5.

[0030] Based on Embodiment 1, in order to prevent leakage when extracting the parent radionuclide from container 5, the second protective chamber 4 is fixed inside the first protective chamber 3. The first top cover 1, the second top cover 8, and the third top cover 9 have the same diameter and correspond to each other's axes. The upper surface of the first top cover 1 is provided with a first through hole 2, which penetrates the first top cover 1. The side surface of the first top cover 1 is fixed with a first annular block 12 and a first connecting block 13. The first baffle 14 is fixed to the end surface of the first connecting block 13. The inner wall of the upper opening of the first protective chamber 3 is provided with a first annular groove 15 and a first connecting groove 17. The first receiving groove 16 is opened on the inner wall side surface of the first connecting groove 17. The first baffle 14 corresponds to the first receiving groove 16 and is movably engaged. The first annular block 12 corresponds to the first annular groove 15 and is movably engaged. The engagement of the first annular block 12 and the first annular groove 15 provides support and positioning for the first top cover 1, preventing the first top cover 1 from falling or shifting during rotation.

[0031] The upper surface of the second top cover 8 is provided with a second through hole 6 and a sliding groove 7. The second through hole 6 penetrates the second top cover 8. A second connecting block 20 and a second annular block 21 are fixed to the side surface of the second top cover 8. A second baffle 19 is fixed to the end surface of the second connecting block 20. The inner wall of the upper opening of the second protective compartment 4 is provided with a second connecting groove 23 and a second annular groove 24. A second storage groove 22 is opened on the inner wall side surface of the second connecting groove 23. The second baffle 19 corresponds to the second storage groove 22 and is movably locked. The second annular block 21 corresponds to the second annular groove 24 and is movably locked. The locking of the second annular block 21 and the second annular groove 24 provides support and positioning for the second top cover 8, preventing the second top cover 8 from falling or shifting during rotation.

[0032] A slider 25 is fixed to the lower end of the first top cover 1. A sliding groove 7 corresponds to the slider 25 and is movably engaged. The sliding groove 7 is coaxial with the second top cover 8. The angle between the two ends of the sliding groove 7 and the axis is a right angle. When the first through hole 2 continues to rotate, due to the engagement of the slider 25 and the sliding groove 7, the rotation of the first through hole 2 will drive the second top cover 8 to rotate. A third through hole 10 is opened on the upper surface of the third top cover 9. The third through hole 10 penetrates the third top cover 9. The angle between the first through hole 2 and the second through hole 6 is a right angle, and the angle between the second through hole 6 and the third through hole 10 is a right angle. The first through hole 2, the second through hole 6, and the third through hole 10 have the same diameter. Since the suction rod has the same diameter as the first through hole 2 and both of their contact surfaces are made of rubber, the contact surfaces of the two will form a seal when the suction rod is inserted into the first through hole 2. At the same time, since the first through hole 2, the second through hole 6, and the third through hole 10 have the same diameter, when the suction rod extracts the parent radionuclide from the container 5, the parent radionuclide will not disperse to the outside world because the first through hole 2, the second through hole 6, and the third through hole 10 are connected, thus avoiding physical harm to the operator.

[0033] In actual use, when extracting the parent radionuclide from container 5, the suction rod of the extraction device is first inserted into the first through hole 2. The size of the suction rod is the same as the diameter of the first through hole 2, and the contact surfaces of both are made of rubber. Then, the first through hole 2 is driven to rotate 90 degrees. At this time, the first through hole 2 will correspond to the second through hole 6. The suction rod can then be inserted into the second through hole 6. While the first through hole 2 is rotating, it will drive the slider 25 to make an arc movement in the slide groove 7. So when the first through hole 2 rotates 90 degrees, the slider 25 is exactly pressed against the inner wall of the end of the slide groove 7 near the second through hole 6. Therefore, when the first through hole 2 is driven to rotate, due to the locking of the slider 25 and the slide groove 7, the rotation of the first through hole 2 will drive the second top cover 8 to rotate. When the first through hole 2 rotates 90 degrees again, the first through hole 2, the second through hole 6 and the third through hole 10 correspond. At this time, the suction rod can be inserted into container 5 through the third through hole 10 to extract the parent radionuclide inside container 5.

[0034] After extraction is complete, the suction rod is sequentially pulled out of the third through hole 10, the second through hole 6, and the first through hole 2. Due to the elasticity of the first spring 11 and the second spring 18, the first spring 11 and the second spring 18 will immediately reset the first top cover 1 and the second top cover 8, so that the first through hole 2, the second through hole 6, and the third through hole 10 are no longer connected, thus achieving automatic sealing protection of the parent radionuclide.

[0035] Since the suction rod and the first through hole 2 have the same diameter and their contact surfaces are both made of rubber, a seal is formed when the suction rod is inserted into the first through hole 2. At the same time, the first through hole 2, the second through hole 6, and the third through hole 10 have the same diameter. Therefore, when the suction rod extracts the parent radionuclide from the container 5, the parent radionuclide will not disperse to the outside world because the first through hole 2, the second through hole 6, and the third through hole 10 are connected, thus avoiding physical harm to the operator.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
