Functions And Precautions Of Medical Radiation Protection Door?

Four functions of medical Radiation Protection Door

1. Shielding function
The X-ray protective door is generally made of stainless steel plate, lead and other materials, with a keel inside and a shielding plate. The shielding plate will be customized according to the different materials and thicknesses of the ray instruments in different environments, so that the staff will be affected. The radiation dose is lower than the value stipulated by the state.

2. Chain function
At present, the more advanced electric ray protection door can be linked with the power supply of the irradiation device. The design program makes it impossible to start the X-ray machine when the door is opened. If the X-ray device is opened when the door is opened, it will be shut down immediately within 2 seconds, so as to ensure the safety of the staff. .

3. Automatic function
The switch of the radiation protection door can be connected with the computer, and the real-time status of the radiation protection door can be displayed on the computer, and the working status can be displayed on the LED display on the door, realizing various control methods such as computer control, button control and manual control, etc. Truly automate.

4. Induction function
Most radiation protection doors integrate position sensors and infrared detectors. If someone approaches or touches the door during the closing process, the door can stop closing immediately and open automatically. It has the functions of travel travel, limit, and time protection.
All in all, the functions of the current radiation protection door have been relatively perfect, not only more humanized, but also the safety performance is constantly improving.

Of course, its functions are far more than that. How to shield more types of rays and how to further improve the shielding rate are the main directions of current research. In the future, there will be thinner, more practical, more humanized, and more The safe radiation protection door enters the hospital and laboratory, and becomes the "patron saint" of the staff's health.

What must be paid attention to when cleaning the radiation protection door of medical protective lead door?

Many hospitals do not know how to maintain and clean the medical protective lead doors after purchasing them, so today the manufacturer will summarize the precautions for welding maintenance and cleaning of the medical protective lead doors and medical radiation protection doors:

Medical protective lead doors for radiation protection General medical rays are X-rays generated by power supply (220-380V) passing through the "high-level head" of the machine. These rays are generally X-rays (high-power machines such as: accelerators, etc. (200KV-10MV) Gamma rays and neutron rays will be produced. This kind of radiation is commonly called ionizing radiation. This kind of radiation can be used as a means of medical examination, but at the same time it causes great damage to the human body.

The general voltage of X-ray room and DR room is 80KV-120KV and the current is: 2-300MA (X-ray room). The National Center for Disease Control requires that the room area is not less than: 24 square meters, and the protection amount is: 2mmpb, which is 2mm lead plate. amount of protection.

1. Internal steel skeleton structure: lead composite board composite inner skeleton, stainless steel door side, door frame, aluminum plastic board decorative panel 2mmpb lead plate.
2. Lead protective treatment for protective door frames and walls.

Attention should be paid to the welding of the lead door:
(1) In order to avoid welding deformation of the lead protective door, symmetrical welding (including butt welding, vertical welding and oblique welding) should be used during welding;
(2) During the welding process of the lead protective door, remove the slag and spatter from the weld seam one by one, and grind the defects with the angle grinding wheel in time to remove the defects;
(3) After the welding work of the lead protective door is completed, the welding seam area and the welding work site should be cleaned up and transferred to the next welding node.
(4) Carry out post-weld inspection;
(5) Wait for the weld seam to cool down, and then inspect the appearance of the weld seam;
(6) There shall be no cracks in the weld, the weld metal and the base metal are completely fused, and all the cracks are filled;
(7) Welds should not overflow;

Only in this way can the quality of the lead door be guaranteed without missing lines or deformation. Can be put into use with confidence. There is a warning light on the upper part of the door, and the interlocking device of the door machine (that is, when the door is closed and the machine is opened, the warning light box above will light up (rays are dangerous, and the light is on and no entry is allowed).
