Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, in particular to a real-time measuring device for the residual amount of a Chinese medicine solution for radioactive drug injection. Background Art

[0002] With the development of nuclear medicine, radionuclide drugs have played an important role in the diagnosis and treatment of several serious diseases (tumors, cancer, cardiovascular and cerebrovascular diseases, etc.). Nuclear medicine molecular targeted therapy for malignant tumors has been a hot topic and a frontier in tumor treatment in recent years. It can guide treatment based on the individual patient's condition at the molecular level, reduce adverse reactions, and improve treatment efficacy. During radiotherapy, some radionuclide drugs (such as 177Lu-DOTATATE and 131I-MIBG) require intravenous infusion. Understanding the radioactive drug residue and radioactivity level is essential for treatment effectiveness. Because radionuclide drugs must be stored inside lead shielding tanks during transportation, storage, and injection, traditional measurement methods can only measure the activity of the radioactive drug placed outside the shielding tank before injection and after removal from the shielding tank after injection. Measurement of the drug's radioactivity during the injection process is not possible. Traditional lead shielding tanks are sealed and cannot be visualized. Medical staff can only judge whether the radionuclide drug has been completely infused into the patient's body by repeatedly observing whether the liquid in the infusion tube has dripped out. It is impossible to accurately and in real time observe the changes in the remaining amount of radionuclide drugs in the lead shielding tank.
