Radionuclide liquor automatic separate-charging apparatus and method thereof

Abstract

The invention discloses a radioactive soup self-separator, which comprises the following parts: PLC controller, mechanic extraction device, air-operated control device, product bottle, activity measuring cylinder and injector, wherein the mechanic extraction device, air-operated control device and activity measuring cylinder connect the PLC controller electrically through control wire; the product bottle is set in the activity measuring cylinder; the injector connects the air-operated control device, which connects the mechanic extraction device. The invention guarantees the accuracy and separating precision, which possesses good protective property.

Description

1. Technical field [0001] The invention relates to a dispensing device and a dispensing method, in particular to an automatic dispensing apparatus for radionuclide medicinal liquid and a dispensing method thereof. 2. Background technology [0002] At present, the radiopharmaceuticals needed by PET centers at home and abroad, such as choline [C-11]-HOLINE, 2-[F-18]-fluoro-2-deoxyglucose (FDG), etc., are all produced by cyclotrons, and the finished drugs are finally It is stored in a sterile vial for use. From the end of production to within 9 hours thereafter, the staff need to manually extract a certain dose of radiopharmaceuticals from the vial and inject them into the body of the examinee. The dose ranges from It varies from 5 to 15mci. The dose size required for inspection is relatively strict. There are two disadvantages in manual extraction: one is that the predetermined amount cannot be accurately extracted, and the other is poor repeatability. The syringe cannot extr...

AI Technical Summary

Problems solved by technology

The dose required for inspection is relatively strict. There are two disadvantages in manual extraction: one is that the predetermined amount cannot be accurately extracted, and the other is poor repeatability. The syringe cannot extract a suitable volume of liquid medicine every time.

[0004] The inaccuracy of manual dispensing, poor repeatability and exposure to too much radiation are the three main drawbacks of traditional dispensing methods

[0005] There is a packaging method in foreign countries, which is to directly transport the radionuclide liquid into the protective device, and then pump the liquid into the syringe through a peristaltic pump, but there are also shortcomings such as inaccurate packaging, poor repeatability, and inconvenient operation.
