An electromagnetically driven safety radiation box

Abstract

The invention relates to the field of medical equipment, and provides an electromagnetically driven safety radiation box, a fixedly connected lower packaging board and an electromagnetically driven safety radiation box body, and radiation holes arranged on the sides of the lower packaging board and the electromagnetically driven safety radiation box body Electromagnetic controller for opening and closing the door; a radioactive source chamber is arranged in the box body of the electromagnetically driven safety radiation box, and the radioactive source is arranged in the radioactive source chamber through the radioactive source fixing conical coil; a radioactive hole is arranged under the radioactive source chamber The opening and closing door activity chamber, the opening and closing door of the radiation hole is arranged in the activity chamber of the opening and closing door of the radiation hole, the opening and closing door of the radiation hole is connected with the push spring, and the pushing force of the spring can make the opening and closing door of the radiation hole move to the left in the moving chamber of the opening and closing door of the radiation hole, The electromagnetic controller of the radiation hole switch door attracts the magnetic force to make the radiation hole switch door move to the right in the movable cavity of the radiation hole switch door; the lower packaging board has a radiation hole; it can greatly reduce the production cost of precision radiation therapy equipment and cold sterilization equipment Operating costs.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an electromagnetically driven safety radiation box. Background technique [0002] According to relevant epidemiological data in our country, malignant tumors are increasing year by year, becoming one of the major causes of death in our country. The treatment methods for malignant tumors mainly include surgery, radiotherapy, chemotherapy and biological immunotherapy, etc., and about 70% of tumor patients need radiotherapy, and radiotherapy has become the main method for treating malignant tumors. [0003] Radiation is produced by radioactive isotopes Co60 or Cs137, etc. γ-rays, which are high-energy electromagnetic waves with a short wavelength (0.001-0.0001nm), strong penetrating power, long range, and uniform dose, have been widely used in malignant tumor treatment and food , Cold sterilization and disinfection of medicines and medical devices. [0004] At present, t...

AI Technical Summary

Problems solved by technology

[0004] At present, there are mainly two types of radiotherapy, one is to use Co60 as the radiation source, and the other is to use the linear accelerator system as the radiation source; the former has a great impact on the radiotherapy because of the weak strength of a single source and the lack of safe miniaturized core components. Its promotion and application; the latter is very expensive because of its high technical complexity, high application and maintenance costs, and very difficult manufacturing technology, which greatly restricts its application range and greatly increases the economic burden on patients
