With the medical radiation protection device 100 of the embodiments of the present invention, the user does not wear a heavy lead garment, thereby reducing the burden on medical personnel and improving the protection effect.
Table 1, table 2, fig. 8 and fig. 9 show radiation data of the medical radiation protection device 100 according to the invention and a conventional lead garment.
TABLE 1 radiation data using medical radiation protection devices
Table 2 radiation data using conventional lead garment
It can be seen from the examination and analysis data that, in both X-ray fluoroscopy and Digital Subtraction Angiography (DSA), the area under the user's knee is "unprotected" because the conventional lead garment cannot cover the area under the knee (about 35cm from the ground) (if the lead garment covers the area under the knee, the doctor wearing the conventional lead garment is not convenient to move freely during the operation).
The highest ambient dose equivalent rate in fluoroscopy reaches 11.57 +/-0.06 mu Sv/h and the highest ambient dose equivalent rate in DSA reaches 26.33 +/-0.25 mu Sv/h at a position about 35cm away from the ground outside the medical radiation protection device 100. After use of medical radiation protection device 100, the dose equivalent rate around each height (height from the ground) within the device, whether in the fluoroscopic or DSA state, is lower than the dose equivalent rate around the same height when protected by a lead garment. Therefore, the protection effect of the medical radiation protection device 100 disclosed by the invention is better than that of the traditional lead clothes.
Outside of the medical radiation protection device 100, the ambient dose equivalent rate rises rapidly (e.g., more than 40 μ Sv/h at 110cm from the surface in the DSA state), both in fluoroscopy and in the DSA state. The higher the height, the higher the peripheral dose equivalent rate. The disclosed medical radiation protection device 100 can control a majority of the ambient dose equivalent rate to about a background radiation value (also referred to as background radiation), i.e., a radiation value in air. Most of the peripheral dose equivalent rate was controlled below 0.2. mu.Sv/h.
The medical radiation protection device 100 disclosed by the invention can effectively protect the lower limb part with the height of less than 35cm from the ground, and has the same protection effect with the part with the height of more than 35cm from the ground, which is obviously superior to the traditional lead coat protection.
The radiation data for the shield (1.0 lead equivalent) or a conventional lead garment (0.5 lead equivalent) with a lead baffle attached is shown in table 3, table 4, fig. 10 and fig. 11.
TABLE 3 radiation data using a medical radiation protection device (1.0 lead equivalent)
Table 4 radiation data using a conventional lead garment (0.5 lead equivalent)
Outside of the medical radiation protection device 100, the ambient dose is rapidly increasing (e.g., more than 7 μ Sv/h at 110cm from the ground in DSA), both in fluoroscopy and in DSA. The higher the height, the higher the peripheral dose equivalent rate. The disclosed shield apparatus 100 can control a majority of the ambient dose equivalent rate below the background radiation level (the level of radiation in the air). Most of the peripheral dose equivalent rate was controlled below 0.1. mu. Sv/h.
Therefore, the protective device 100 disclosed in the present invention can use a protective material with a larger thickness made of lead or other materials, so as to achieve a better protective effect.
In the previous description, numerous specific details were set forth in order to provide a thorough understanding of the present invention. The foregoing description is only a preferred embodiment of the invention, which can be embodied in many different forms than described herein, and therefore the invention is not limited to the specific embodiments disclosed above. And that those skilled in the art may, using the methods and techniques disclosed above, make numerous possible variations and modifications to the disclosed embodiments, or modify equivalents thereof, without departing from the scope of the claimed embodiments.
