Description

Self-control type X-ray protection cabin

Technical Field

The invention belongs to the field of medical X-ray protection appliances, and particularly relates to an automatic control type X-ray protection cabin.

Background

At present, radiation protection equipment such as a lead vest, a lead scarf, a triangular towel, lead glasses, a lead cap and the like is commonly used clinically for carrying out radiation protection on operators. There are two major drawbacks to this approach: firstly, the protection is not thorough, the current equipment mostly has only 0.5mm lead equivalent, even if the current equipment is in an exposed state due to the limit of the weight bearing of a human body, and the four limbs, the face and other parts are close to a patient at the bedside, the radiation quantity can only be reduced by about 80 percent, so that the X-ray has very great harm to an interventional diagnosis and treatment operator due to the long-term accumulation effect, and the caused result is panic and the extensive attention of related medical workers to a certain extent. Secondly, the weight is big, ventilation condition is poor, and the human body directly bears a weight, easily produces tired, has restricted operator's operating time. Sometimes, to be able to do long-term work, the operator has to discard part of the guard. Current interventional procedures can be said to be typical of procedures that come at the expense of health of healthcare workers. Radiation damage has led many physicians to take away from work, and the incomplete radiation protection has hindered to some extent the further application and development of interventional diagnosis and treatment disciplines. The protection problem of interventional diagnosis and treatment is paid attention to, and the knowledgeable doctor and radiation protection expert in the interventional radiology industry call for strengthening the propaganda force on the interventional protection problem.

In order to reduce the damage of radiation to medical practitioners, various attempts have been made to design different protective equipment from conventional protective equipment. For example, a cross-shaped closed type universal combined type interventional protection device and a multifunctional X-ray protection lead screen special for interventional diagnosis and treatment are relatively fixed and inconvenient to move, so that the overall layout of an interventional room and the actual operation of an operator are affected, and the feasibility and the practicability are poor. The zeroGray ray protection system produced by the CFIMedicalsolution research in the United states has no protection on the back surface, the top of the head, the arms, the ankles and other parts, so that the zeroGray ray protection system can only play a role in delaying the injury of rays to human bodies. Meanwhile, if the operator is away from the examination bed in case of malfunction, the protection device is completely disabled. The fixed or movable suspension occupies a large space and is not suitable for a plurality of devices to work together.

In summary, the existing X-ray protective clothing has the following defects:

1. the total weight of the operator is more than ten kilograms after wearing the protective lead coat, the lead scarf and the lead glasses, and some of the operators are even heavier, the operators often work for a plurality of hours, and the long-time load can cause lumbar vertebra diseases and knee joint diseases, so that the physical health of the operators is seriously affected;

2. the manufacturing weight of the lead clothing is limited, and some parts of the lead clothing are often protected by adopting a method of local protection and low lead equivalent weight, so that a plurality of parts of the body of the lead clothing cannot be protected, and the lead clothing is directly exposed to the irradiation of X rays, so that the lead clothing is greatly damaged to an operator;

3. the lead garment is airtight, the lead garment is heavy and can be tightly pressed when being worn, an operator often can sweat down back, and bacteria are easy to generate to cause skin diseases;

4. in order to reduce the radiation to the body as much as possible, an operator usually adopts to withdraw rapidly after finishing one important operation, and then carries out the next operation when stopping exposure, so that the operator repeatedly goes in and out, and more importantly, the operator cannot control and observe the whole process of a patient operated under X-rays, is easy to go out of errors, and has a certain influence on the treatment effect.
