Radiation dose detection device for irradiation equipment, irradiation equipment and detection method

Abstract

The invention provides a radiation dose detection device for irradiation equipment, the irradiation equipment and a detection method, and relates to the technical field of medical instrument detection, the radiation dose detection device for the irradiation equipment comprises a cover plate, a fixing assembly and a probe assembly; the cover plate covers the top end of the rotary container and is provided with a via hole communicated with an inner cavity of the rotary container; the fixing assembly comprises a rotating piece, the rotating piece is in rotating fit with the cover plate, and the rotation axis of the rotating piece is parallel to the rotation axis of the cover plate rotating along with the rotating container. The probe assembly is fixed to the rotating part and comprises a detection probe penetrating through the via hole. By means of the radiation dose detection device for the irradiation equipment, the technical problems that in the prior art, leakage of water in a blood cup is likely to be detected, and a final test result deviates are solved, and the accuracy of calculating performance parameters such as the central dose rate and/or the irradiation uniformity of the irradiation equipment is improved.

Description

technical field [0001] The invention relates to the technical field of medical device detection, in particular to a radiation dose detection device for irradiation equipment, irradiation equipment and a detection method. Background technique [0002] At present, high-energy ray irradiation technology is widely used in food, seeds and medical devices. Among them, X-ray irradiation equipment is a medical device used to irradiate blood. Its core performance lies in the central dose rate and irradiation uniformity. , according to the current general knowledge in the industry, a predetermined dose of X-ray irradiation is completed in the sample rotating container in the minimum load state and full load state of the X-ray irradiation equipment, and the absorbed dose C of the sample at any point in the sample rotating container should satisfy : 25Gy≤C≤50Gy. [0003] The absorbed dose can be tested by various methods, such as thermoluminescent film method, film method and ionizatio...

AI Technical Summary

Problems solved by technology

However, in this detection device, since the rotating drive support of the probe mounting bracket is set in the detection blood cup, and passes through the through hole at the bottom of the detection blood cup to be connected with the rotation drive mechanism of the blood cup tray, during the test , the water in the detection blood cup may leak; in addition, since the detection blood cup is also connected with the blood cup tray rotation drive mechanism through the blood cup tray fixed at the bottom, if the detection blood cup and the blood cup tray rotation drive mechanism The relative sliding between them will cause the detection blood cup and the rotating drive support to rotate asynchronously, which will lead to the deviation of the test results
