Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and more specifically, to a splash-proof sealed container for mixing radiopharmaceutical raw materials. Background Technology

[0002] Nuclear medicine is an emerging discipline that uses nuclear technology to diagnose, treat, and study diseases. In medicine, radioactive isotopes and nuclear radiation can be used for diagnosis, treatment, and medical scientific research; in pharmacy, they can be used to study the mechanism of drug action, determine drug activity, analyze drugs, and sterilize drugs by radiation.

[0003] A search revealed application CN202311071697.7, entitled "A Safe and Sealed Uniform Mixing Device for Radiopharmaceutical Synthesis." This application addresses the issues of inefficient heating and stirring of radiopharmaceutical reagent mixing equipment, the short shelf life of radiopharmaceuticals due to their short half-life, and the need for immediate preparation and use. It also notes that harmful gases and even radiopharmaceutical emissions can escape during the equipment's opening and drug release process, causing indoor air pollution and increasing the risk to workers preparing drugs on-site. The proposed solution involves a temperature-controlled stirring component inside the mixing chamber to mix the drug solution and prepare the radiopharmaceutical. An electric heater heats the radiopharmaceutical to a specific temperature to ensure its activity, while a vibrating motor vibrates the mixing chamber to ensure uniform mixing. However, the stirring component is prone to splashing materials during stirring, leading to leakage and waste, affecting production safety and stability. Furthermore, the complex surface structure of the stirring component makes cleaning difficult. Further improvements are needed.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
