Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically a lead-containing radiation protection mask. Background Technology
[0002] In digital subtraction angiography (DSA), which uses X-ray imaging, medical personnel may be exposed to scattered radiation during the procedure. The core principles of radiation protection are time, distance, and shielding: minimizing exposure time, increasing distance from the radiation source, and using shielding materials with sufficient lead equivalent. Lead-containing protective masks can protect the face and reduce the impact of radiation.
[0003] In response to this, utility model patent CN217446779U discloses a protective mask, including a mask body and straps; the protective mask also includes a pressure-reducing part, which is disposed in the straps and is used to reduce the pressure of the straps on the ears. This protective mask has a simple structure, can avoid pressure injuries, and is highly comfortable to wear.
[0004] However, the protective masks in the aforementioned patent applications still have some problems: traditional lead rubber masks are heavy, and long-term wear can easily cause facial pressure marks and fatigue. The seal in areas such as the bridge of the nose and chin is insufficient, resulting in reduced radiation scattering protection efficiency. At the same time, their breathing resistance is high, affecting operational comfort. Existing lead rubber masks are difficult to combine with eye protection, resulting in multiple and complicated equipment worn by personnel. Utility Model Content
