Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an automatic storage, elution and purification device for a Mo-Tc generator. Background Art

[0002] Mo-Tc generator is a commonly used generator in medicine. Mo-Tc generator can produce test solution containing radionuclides through elution. For example, Mo-Mo-Tc generator can produce 99mTc, which can be used to label drugs and cooperate with nuclear medicine equipment such as SPECT for nuclear medicine imaging examination. Sr-Rb generator can produce 82Rb, which can be used with PET and other equipment for nuclear medicine examination, such as myocardial perfusion metabolic imaging.

[0003] However, since the Mo-Tc generator can produce a test solution containing radioactive nuclides through leaching, and it is well known that the test solution containing radioactive nuclides can cause harm to the human body, if the protection during the leaching process is improper, the personal health of the operator cannot be protected. At present, the leaching operation is done manually, and the operator can only be protected by wearing protective clothing, but the protection level is not enough and there are still safety hazards.

[0004] Therefore, there is an urgent need for a medical device that can automatically store and rinse and improve the level of protection to achieve the above operations and ensure the health of operators. Utility Model Content

Then remove the protective devices on the single and double needles of the 99Mo-99mMo–Tc generator, insert the sodium chloride elution solution bottle on the double needle of the 99Mo-99mMo–Tc generator, and then insert the lead protective tank containing the negative pressure bottle on the single needle for elution. After the elution solution in the sodium chloride elution solution bottle is drained, remove the negative pressure bottle containing the sodium pertechnetate [99mTc] acid eluent, and then use another negative pressure bottle to insert it into the single needle to drain the adsorption column of the generator. Then send the sodium pertechnetate [99mTc] acid eluent obtained by elution to the marking post for measurement and standby.
