Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a radioactive drug micro-dispensing device. Background Art

[0002] Radioactive drugs refer to radionuclide preparations or their labeled compounds used for clinical diagnosis or treatment. In order to facilitate storage and transportation, radioactive drugs are mostly produced in the form of concentrated liquids. Their end users need to dilute them into liquids before clinical use. The substances emitted by radioactive drugs are carcinogenic.

[0003] The patent number is CN2453424Y, which is a radioactive drug micro-dispensing device, comprising a needle, a piston syringe, and a tee. The device is characterized in that two needles (2 and 3) are arranged in front of the piston syringe (4), and a tee (1) is arranged between the syringe (4) and the two needles (2 and 3), and the tee (1) is adjustable. The device has the advantages of simplifying the operation steps of liquid dispensing, one-time acupuncture, multiple dispensing, and reducing the working error during dispensing. The device is easy to operate, low in cost, and easy to clean and disinfect. The device can be widely used in the dispensing of radioactive drug liquids, flammable and explosive volatile liquids, and highly toxic liquids, and can also be used for chemical analysis such as pipetting and titration of various reagents. During use, the device lacks a dilution mechanism, making it difficult to fully dilute the radioactive drug, resulting in leakage of radiation when the radioactive drug is diluted.

[0004] Radioactive drugs need to be diluted into liquids before they can be used clinically. There are many steps in the packaging and dilution of radioactive drugs. The longer the radioactive drugs are in contact with the air, the more radiation will leak from the radioactive drugs, and the greater the impact on medical staff. Utility Model Content
