The frame type chest film protective screen is an innovation based on the single column chest film protective screen, which is more stable. The size is 1800 * 600, and it is processed with 304 stainless steel pipe. The protection shall not be less than 0.5mmpb. It is suitable for shooting, and the upper and lower height can be adjusted. It is composed of upper and lower protective curtain, which is used to protect the part of human body not photographed by X-ray machine. The protective curtain can slide vertically up and down, which is suitable for both adults and children - it is suitable for shooting people in ortho position, lateral position, cervical spine and different body types - the size of upper and lower protective curtain (mm): 300 × 660, 420 × 660, lead equivalent of protective curtain: 0.5mmpb. When using the lifting type radiation protection lead curtain for medical image examination, it is only necessary to set the protective lead curtain between the human body and the medical image examination equipment (ray source). By controlling the driving device to drive the rotating shaft and the lifting of the protective curtain, the height of the protective curtain can be adjusted to cover the non examination parts of the human body, so that the irradiation window only exposes the examination parts, which can prevent the non examination parts of the human body from being damaged When it comes to the damage, there is no need to give the patient protection guidance, which saves the time of examination. Under 120 kV tube voltage, the lead equivalent of curtain is not less than 0.5 MMPB.
