Description

Technical Field

[0001] This utility model relates to the field of activation equipment, specifically a fully automatic activation device for an FDG synthesizer. Background Technology

[0002] Fluorine-[18F]deoxyglucose injection (18F-FDG) is the only positron emission tomography (PET) radiopharmaceutical approved in China. It is used for imaging of the brain, myocardium, tumors, and inflammation. Its synthesis process uses an FDG synthesizer, and the activation device is a piece of equipment used in conjunction with the FDG synthesizer.

[0003] With the increasing application of thermal desorption technology in environmental protection, food, medical, and environmental monitoring fields, the demand for its essential component, the desorption tube, is also growing. Therefore, the activation and regeneration of the desorption tube is crucial. Activation of the desorption tube is primarily achieved through a specialized activation device. Existing activation equipment, when activating the sampling tube, releases any incompletely desorbed impurities from the tube, while toxic and harmful gases are directly discharged, potentially endangering the health of operators and polluting laboratory air.

[0004] According to patent document CN218725917U, a fully automatic activation instrument includes an instrument body and a base. The instrument body is fixed to the base via a back plate. An electric heating block is provided on the base, and heating slots for placing the sample tubes are arrayed on the electric heating block. An air blowing mechanism is also provided inside the base, along with an adsorption fan and a protective cover. The adsorption fan is located at the lower end of the instrument body. In use, the protective cover surrounds the electric heating block, forming a relatively sealed environment. This prevents heat loss and improves heating efficiency, while also preventing the indiscriminate emission of toxic and harmful gases, thus protecting the environment and operators. The protective cover is controlled by a lifting mechanism for automatic raising and lowering. While this solution avoids heat loss, it cannot sufficiently and quickly heat the sample tubes through the heating mechanism, resulting in inconvenience during use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fully automatic activation device for FDG synthesizer to solve the problems mentioned in the background technology. The utility model has a novel structure. In use, after the sampling tube is fixedly installed inside the groove, the movable column moves upward under the pull of the ring seat. The movable column moves upward and exposes the sides of the sampling tube, which heats the sampling tube over a large area quickly, thereby effectively improving the activation speed.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a fully automatic activation device for an FDG synthesizer, comprising a base, a fixed frame fixed on the base, a fixed box fixed on the top of the fixed frame, an exhaust duct fixedly installed on the top of the fixed box, a movable box movably installed inside the fixed box, a movable plate and a support plate movably installed on the sides of the fixed frame, protrusions fixedly installed on the sides of both the movable plate and the support plate, an observation window fixedly installed on the support plate, and an air inlet pipe and a filter assembly fixedly installed on the sides of the base.

[0007] Furthermore, a support base is fixed to the top of the base, the support base has a groove, a limit ring is fixedly installed on the inner wall of the groove, and an exhaust fan is fixedly installed inside the exhaust duct.

[0008] Furthermore, the sides of the groove are respectively provided with fixing holes and openings, a movable column is movably installed inside the fixing holes, and a ventilation hole is provided at the bottom of the fixed box.

[0009] Furthermore, a friction seat is fixed to the bottom of the movable column, the friction seat is movably installed inside the fixing hole, and a ring seat is fixed to the top of the movable column.

[0010] Furthermore, a heating mechanism is fixedly installed inside the movable column, and a fixing tube is fixed to the bottom of the fixing hole and the support base, with the fixing tube installed inside the base.

[0011] Furthermore, a slider is fixedly installed on the side of the fixed frame, and a sliding groove is opened on the inner wall of the movable plate and the support plate. The slider is movably installed inside the sliding groove, and an adsorption plate is fixedly installed inside the movable box.

[0012] The beneficial effects of this utility model are:

[0013] 1. This fully automatic activation device for an FDG synthesizer, in use, after the sampling tube is fixedly installed inside the groove, the movable column moves upward under the pull of the ring seat. The movable column moves upward and exposes the sides of the sampling tube, which heats the sampling tube over a large area quickly, thereby effectively improving the activation speed.

[0014] 2. This fully automatic activation device for an FDG synthesizer allows air to enter through an opening. The airflow entering through the opening flows along the side of the test tube, which can quickly remove the high temperature on the sampling tube, thus facilitating rapid cooling of the sampling tube.

[0022] In this embodiment, the sides of the groove 13 are respectively provided with fixing holes 15 and openings 14. A movable column 16 is movably installed inside the fixing hole 15. A ventilation hole is provided at the bottom of the fixed box 2. A friction seat is fixed at the bottom of the movable column 16 and is movably installed inside the fixing hole 15.

[0023] In use, the movable plate 5 and support plate 6 are slid to the sides, moving along the slider 11 via a groove. After opening the support plate 6 and movable plate 5, the internal support seat 12 is exposed. The sampling tube is then installed inside the groove 13. A limit ring, made of rubber, is fixed to the inner wall of the groove 13, limiting and fixing the sampling tube. After the sampling tube is fixed, the movable column 16 is moved upwards via the ring seat 17, increasing the heating area for the sampling tube. After the movable column 16 is removed, the support plate 6 and movable plate 5 are closed, allowing the space of the support seat 12 to be... The heating mechanism inside the sealed movable column 16 generates high temperature, which directly heats the sampling tube. At the same time, the exhaust fan 19 is activated, and the exhaust fan 19 draws air in from the filter assembly 10 into the base 1.
