Description

Technical Field

[0001] The utility model relates to a shaking device for a PET quality control model, in particular to a radiation protection screen for shaking a PET quality control model. Background Art

[0002] Operators of PET / CT equipment need to perform quality control verification on PET crystals every week. During the operation, radioactive isotope 18F liquid and distilled water need to be filled into a bottle-shaped quality control model first, and then the quality control model is slowly shaken by hand to be mixed evenly before it can be used for quality control. In the prior art, the method of manually shaking the quality control model by the operator has the following deficiencies:

[0003] First, since the radioactive isotope 18 F is a non-sealed radiation source, the emitted rays have high energy and strong penetration power. During the time-consuming shaking operation, it will cause radiation hazards to personnel.

[0004] Second, when manually holding the quality control model and shaking it, the operation is laborious, and the liquid mixing uniformity is not ideal.

[0005] Third, when manually shaking, it is easy to have operation errors, such as the model bottle slipping and breaking, and the liquid spilling, which will cause radioactive contamination and is extremely difficult to clean up.

[0006] Fourth, the manual shaking action is relatively slow, the shaking time is relatively long, and the efficiency is low.

[0007] Fifth, there is no radiation protection product on the market that can assist in shaking the quality control model. Summary of the Utility Model

[0012] Wherein, the driving member can be a manual driving member or an electric driving device; the shaking operation can be a rotational motion, a linear reciprocating motion, a translational motion or other motion modes.

[0013] The bottle rack is used for loading the quality control model.

[0014] Thus, the usage method of the radiation protection screen of the present utility model is as follows:

[0015] First, seal the quality control model containing the radioactive isotope 18 F solution and place it in the bottle rack for fixation;

[0016] Secondly, connect the bottle rack to the shaking transmission mechanism directly behind the radiation protection door. After completion, the operator quickly evacuates to the front of the radiation protection door to utilize the radiation protection door to avoid the radiation damage of the radioactive isotope 18 F solution;

[0017] Then, drive the shaking transmission mechanism through the driving member to shake the bottle rack and the quality control model until the radioactive isotope 18 in the quality control model is evenly mixed;

[0018] Finally, take out the quality control model from the bottle rack and move it to the PET / CT device for the PET quality control process.

[0019] Thus, the present utility model is provided with a radiation protection door, a shaking device and a bottle rack. The operator can drive the shaking transmission mechanism through the driving member of the shaking device to shake the bottle rack and the quality control model therein. During the shaking process, the operator and the driving member are located in front of the radiation protection door, and the radiation protection door can be used to avoid the radiation damage of the radioactive isotope 18 F solution in the quality control model located directly behind the radiation protection door to the operator; therefore, the present utility model can improve the safety of the shaking operation of the quality control model and avoid the operation error problem existing when manually shaking the quality control model.

[0020] As a preferred embodiment of the present utility model: Refer to Figures 1 to 3 and the shaking device adopts the following structure:

[0021] The mounting clamping plate is a U-shaped clamping plate composed of a front side plate, an outer connecting portion and a rear side plate to form the mounting clamping groove; the front side plate and the rear side plate are respectively fixed to the front side and the rear side of the radiation protection door;

[0022] The shaking transmission mechanism is provided with a front shaft bearing assembly, a front synchronous belt transmission assembly, a transmission shaft bearing assembly, a rear synchronous belt transmission assembly, a rear shaft bearing assembly and a rigid coupling; the front shaft bearing assembly, the transmission shaft bearing assembly and the rear shaft bearing assembly are respectively installed on the front side plate, the outer connecting part and the rear side plate; the front shaft of the front shaft bearing assembly, the front driving synchronous pulley of the front synchronous belt transmission assembly and the driving member are coaxially connected, the front driven synchronous pulley of the front synchronous belt transmission assembly and the front end of the transmission shaft of the transmission shaft bearing assembly are coaxially connected, the rear end of the transmission shaft of the transmission shaft bearing assembly and the rear driving synchronous pulley of the rear synchronous belt transmission assembly are coaxially connected, the rear shaft of the rear shaft bearing assembly, the rear driven synchronous pulley of the rear synchronous belt transmission assembly and the rigid coupling are coaxially connected;

[0029] Preferably: A connecting shaft is provided at the middle position of the bottle rack frame for detachably connecting with the rigid coupling of the shaking transmission mechanism. Thus, it is possible to conveniently replace the corresponding model of the bottle rack according to different quality control models, ensuring the compatibility of the radiation protection screen.

Thus, the operator can conveniently view the liquid mixing condition inside the quality control model opposite the door through the leaded glass observation window, and the leaded glass observation window can also protect the operator from radiation hazards.
