Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nuclear medicine packaging, in particular to a nuclear medicine packaging instrument. Background Art
[0002] Radioactive nuclear medicine is mainly used in the field of nuclear medicine ECT examination. When receiving ECT examination, the examinee needs to be injected intravenously with radioactive nuclear medicine imaging agents. Radioactive imaging agents have only extremely small amounts of radioactivity (positron nuclides) and decay very quickly. They can usually be completely cleared from the body within tens of minutes to hours and will not cause harm to the human body. However, it is harmful for medical staff to come into contact with such drugs too frequently and be exposed to them for a long time when taking medicine and injecting them for patients. The radiation source should be effectively shielded through a variety of protective measures.
[0003] After searching, Chinese patent announcement number CN209338085U discloses a radionuclide dispensing instrument, including a shell. The left side and the right side of the shell each have an opening, and a compartment door is movably arranged at each opening. Two lead glass baffles are arranged on the front side of the shell, and a conveyor belt is arranged inside the shell. The conveyor belt is driven by a conveying motor, and an injection structure is arranged above the conveyor belt. The utility model sets the compartment door on the left and right sides of the shell, and the operator stands in front of the shell to operate, and is protected by the lead glass baffle, thereby avoiding the nuclear radiation damage caused by the vertical oblong operating hand hole and the operator facing the setting in the prior art. By setting the injection structure, automatic injection can be performed, which reduces the time of opening the compartment door and improves safety.
[0004] However, in the above technical solution, automatic injection packaging is performed only through an automatic injection structure, which improves the safety of radionuclide packaging. However, in the patent, the medicine bottles are placed on the conveyor belt manually, and there is no mechanism for fixing the medicine bottles on the conveyor belt. When the conveyor belt is started and stopped, it is easy to cause the medicine bottles to slide and shake, causing their positions to change and affecting the normal nuclear medicine packaging.
