Description

A radiation-proof automatic injection box

technical field

The utility model belongs to the technical field of medical care equipment, in particular to a radiation-proof automatic injection box.

Background technique

In recent years, with the continuous development of nuclide therapy technology, more and more patients are treated with nuclide radiotherapy. Among them, many examinations in nuclear medicine require the use of radioactive contrast agents. As we all know, contrast agent (also known as contrast media) is one of the most commonly used drugs in radiodiagnosis, and it is used for CT enhanced examination, interventional angiography, excretory urography and other angiographic examinations. Contrast media can be divided into negative contrast media and positive contrast media according to their molecular weight and X-ray absorption dose. Among them, negative contrast media are mainly gases, including air, oxygen, carbon dioxide, etc., and positive contrast media are mainly barium and iodine-containing contrast media. . Barium is barium sulfate, used for gastrointestinal contrast examination. There are many kinds of iodine-containing contrast agents, which are mainly used for CT enhancement, interventional contrast, urography and other angiographic examinations, all of which are organic iodine agents. It can be seen that the contrast agent has a certain degree of radioactivity, and long-term close contact will cause radiation damage.

Medical staff, especially nurses, often need long-term close contact with radioactive contrast agents during actual operations, which will bring them a large amount of radiation, which will inevitably have an adverse effect on their health. Therefore, it is very necessary to study a device that avoids direct contact of medical personnel and can effectively inject radioactive contrast agents, and it is very worthy of in-depth discussion and research.
