Background With the development of medical radiation detection technology, various radiation detection devices have been widely used. However, these products still have some problems in practical use. For example, medical radiation detectors currently on the market generally employ more traditional detection structures, and the precision and response speed of the medical radiation detectors are difficult to meet the requirements of the modern medical field for high-precision and rapid detection.

The design uploads data to the blockchain node through the 5G communication module, and the test tubes are detected one by combining the storage mechanism, the test tube placement mechanism and the lifting mechanism. Although this design improves the efficiency of manually replacing test tubes, it does not involve high-precision detection techniques in terms of detection structure, and its main focus is on the safety of data transmission and storage, rather than improving detection accuracy and sensitivity. Thus, this approach may not fully meet the requirements in the face of complex medical scenarios requiring high precision detection. Through the search, a medical radiation-proof controllable isolation layer for radiology with the publication number of CN108166906B is disclosed, and the publication date is 2019, 6, 25. The radiation-proof isolation function is realized through components such as the door plate, the pulling module, the electromagnetic lock, the size detector, the LED indicator lamp and the like.
