Description

Technical Field

[0001] The utility model relates to the technical field of radiation protection devices, in particular to a radiation protection device in the running state of a tumor radiotherapy room. Background Art

[0002] A radiation shield is a device used to detect and measure radiation levels in an environment. Radiation shields can monitor different types of radiation.

[0003] Existing technologies include a utility model patent with publication number CN211158202U, which discloses a radiation shield for tumor radiotherapy. The patent includes a bed plate, a protective cover, and a treatment window. The radiation shield for tumor radiotherapy has sliding protective covers on both sides of the upper surface of the bed plate. When the two protective covers abut against each other, they form a hollow rectangular chamber with the bed plate for the patient to lie down for radiotherapy. A locking mechanism for connecting the two protective covers is provided on one end surface of the two protective covers. Multiple treatment windows are also provided on the two protective covers. The radiation shield for tumor radiotherapy forms a rectangular radiotherapy area through the two treatment windows. The radiotherapy area corresponds to a part of the patient's body, such as the torso, head, or legs. This allows external radiotherapy equipment to treat the patient's designated part from within the radiotherapy area, while shielding other parts of the body from the treatment windows, thereby minimizing the area of ​​radiation exposure to other parts of the body.

[0004] In daily use, it is found that the radiation protection device can be installed on the assembly board by screws. When the radiation protection device monitors that the radiation level in the tumor radiotherapy room exceeds the preset safety threshold, the radiation protection device will automatically sound an alarm to remind the staff to pay attention. However, the installation steps of the radiation protection device installed by screws are relatively cumbersome, which also leads to a long installation time. The staff also need to use installation tools for installation, and the radiation protection device is generally installed in the upper part of the assembly board. In order to facilitate installation, workers usually use a stepladder to perform installation work, which also leads to certain safety risks for workers working at heights for a long time. Utility Model Content

The workers also need to use installation tools for installation, and generally the radiation protection device is installed in the upper part of the assembly plate. In order to facilitate installation, the workers usually use a stepladder to perform the installation work, which also leads to the workers working at height for a long time, which poses certain safety risks. A radiation protection device for the operating state of a tumor radiotherapy room is proposed.

[0015] The effect achieved by the above-mentioned components is: after the anti-radiation device body is connected to the power cord, the auxiliary device can be used to improve the stability of the connection between the power cord and the anti-radiation device body, thereby avoiding the situation where the power cord and the anti-radiation device body become loose when connected, causing the anti-radiation device body to fail to work normally.

[0016] Preferably, one end of the elastic sheet away from the adjusting block is fixedly connected to a pressing block.

[0017] The effect achieved by the above components is that when the elastic sheet needs to be pressed, the pressing block installed on the elastic sheet can be used to press the elastic sheet, and the pressing block can improve the efficiency and speed of pressing the elastic sheet.

[0018] Preferably, the bump is a titanium alloy block.

[0019] The effect achieved by the above components is that when the titanium alloy protrusion is engaged with the slot for a long time, the surface of the block is relatively hard, which also makes the protrusion less likely to deform under long-term use, and the use effect is better.

[0020] In summary, the beneficial effects of the present invention are as follows:
