Description

Technical Field

[0001] The invention relates to the technical field of sub-packaging hot chambers, in particular to a full-automatic sub-packaging hot chamber. Background Art

[0002] With the rapid development of nuclear medicine, equipment for the production and related operations of radioactive nuclide drugs has been widely used. Hot cells are one of them. Hot cells are high-radiation protection equipment that provides an effective protection place for the corresponding operations or core equipment during the production and packaging of radioactive nuclide drugs. How to ensure the safety of protection and make the various use requirements of the equipment meet industry specifications while making the operation and use of personnel more reasonable and convenient is the direction of equipment research and development. Radioactive drug packaging hot cells are widely used in nuclear medicine departments of large hospitals, radioactive drug production institutions and radioactive drug research institutions. They are used for the packaging of radioactive drugs such as 18F-FDG. They can keep medical staff away from radiation sources during the drug packaging process and reduce their radiation exposure. They are widely used in the field of nuclear medicine.

[0003] During the use of traditional filling hot chambers, the main body of the hot chamber can only provide a shielding environment. The specific processes of moving in medicine bottles and filling and injecting medicines require manual operation by operators. The degree of automation is low, which increases the burden on operators. At the same time, during the operation, the operator is too close to the radioactive drugs and is close to the radiation environment for a long time, which is likely to have a certain impact on the physical and mental health of the operator. In addition, it is not convenient to clean the hot chamber quickly after use, which is likely to affect the subsequent use efficiency. For this reason, we propose a fully automatic filling hot chamber. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a fully automatic packaging hot chamber. The programming operation is performed by a programmer. The operating parameters of the internal equipment of the device are adjusted and controlled according to the different medicine packaging requirements. In the preparation stage, the bracket is located inside the entry chamber, and the shielding door on one side of the entry chamber is closed. The movable door is opened, and the medicine to be loaded and its external lead can are placed on the top of the bracket. Then the movable door is closed, and the motor drives the rotation of the moving wheel so that the bracket carrying the lead can and the medicine bottle moves along the slide groove to the inside of the hot chamber. The inside of the suction cup is vacuumed through the exhaust pipe so that the suction cup absorbs the lead can cover. Then the power output end of the cylinder moves up to open the lead can, exposing the medicine bottle, and the medicine discharge end of the injection tube is inserted into the medicine bottle for injection. After the injection is completed, the injection tube and the bracket are reset, and the cover is reset to seal the lead can, and the electric hinge is operated. The shielding door of the discharge chamber is opened, and the bracket moves to the inside of the discharge chamber, and then the shielding door is closed. After cleaning, the movable door on one side of the discharge chamber is opened to take out the lead can and the medicine bottle. During the injection process, the ventilation pipe keeps running, and the hot chamber, the entrance chamber and the discharge chamber are ventilated respectively. When the injection is completed, the water pipe is connected, and water is sprayed to different chambers through the spray pipe and the nozzle to clean the environment of each chamber, reducing the impact on the subsequent injection process. The bracket is used to drive the lead can and the medicine bottle to move inside different chambers. At the same time, the supporting injection and other equipment are operated in sequence to automatically complete the injection and packaging operations. No manual operation is required throughout the process, which improves the convenience and safety of operation. The automatic opening and closing structure of the shielding door and the operation of the cleaning system not only ensure the automatic packaging of the medicine, but also effectively isolate the radiation and clean the inside of the device.
