[0021] like Figures 1 to 5In one embodiment of the new radiation protection device for PET / CT scanning of the utility model shown, it includes a detection bed 1, a radiation shielding frame 2 that can be folded and expanded along the detection bed 1, and a radiation protection belt 3 that is detachably arranged on the radiation shielding frame 2. The detection bed 1 is provided with a slideway 11 for the radiation shielding frame 2 to slide. The radiation shielding frame 2 includes a plurality of door-shaped support frames 21 arranged at intervals, and a connection component 4 that can detachably connect the plurality of support frames 21; the connection component 4 includes a plurality of telescopic rods that can be retracted and extended in different lengths; and a plurality of lead blocks arranged in sequence are arranged on the radiation protection belt 3. By arranging a plurality of telescopic rods in conjunction with a plurality of support frames arranged at intervals, a radiation protection space that can be fully moved by the examinee is formed, and by cooperating with the detachable radiation protection belt, the radiation protection device can be quickly installed and disassembled, and can be quickly gathered and folded after use, thereby reducing the demand for storage space.

[0022] Specifically, at least two types of radiation protection belts 3 with different widths are provided; the width of one type of radiation protection belt 3 is twice the width of another type of radiation protection belt 3 .

[0023] Specifically, the support frame 21 includes two vertical sections 23 respectively arranged on both sides of the human body, a horizontal section 24 placed above the human body, and an inclined section 25 connecting the vertical section 23 and the horizontal section 24; the vertical section 23, the horizontal section 24, and the inclined section 25 are all provided with a support groove 22 for positioning and engaging the connecting component 4. By setting up several connecting sections to form a door-shaped support space, sufficient protection for the human body is ensured, and a complete radiation-proof space is formed in conjunction with the connecting component stuck in the supporting groove, and a complete radiation-proof space is realized using simple equipment.

[0024] Specifically, the connecting assembly 4 includes a first connecting rod 41 connecting adjacent vertical sections 23, a second connecting rod 42 connecting adjacent inclined sections 25, and a third connecting rod 43 connecting adjacent horizontal sections 24; the first connecting rod 41 is a multi-section nested telescopic rod that can be pulled out and extended.

[0025] Specifically, a positioning ring 44 matching the supporting groove 22 is provided at the end of each section of the first connecting rod 41 .

[0026] Specifically, a bag 31 for the connection assembly 4 to pass through is provided on one side of the radiation protection belt 3 close to the vertical section 23. By designing a bag for the telescopic rod to pass through, the radiation protection belt to be laid is sheathed on the corresponding section of the telescopic rod, the connecting rod on one side is set up, and then the radiation protection belt is pulled to be set up on the already installed connecting rod, so that the radiation protection belt is laid quickly, effectively reducing the workload of medical staff.

[0029] Working principle: The staff selects a connection component 4 of appropriate length and a matching radiation protection belt 3 according to the height of the person being tested. When testing adults, a wider radiation protection belt 3 is selected, multiple support frames 21 are slid, and the spacing is adjusted to a position equal to the width of the radiation protection belt 3. Each section of the first connecting rod 41 is elongated to the longest state, and the positioning ring on each section is clamped on the corresponding support groove 22 to form a positioning for the spacing of multiple support frames 21. According to the needs of the detection area, the corresponding two support frames 21 are selected without laying the radiation protection belt 3, and other areas are selected with the first connecting rod 41 corresponding to only the number of sections. A telescopic rod is clamped in the support groove 22 on the horizontal section 24 and the inclined section 25 to support the anti-radiation belt 3, forming a complete protection for the non-detection area, and ensuring the activity space of the inspected person, reducing the load impact of the lead block on the human body, and selecting an appropriate area for display and inspection as needed, quickly forming a clear inspection area, and reducing the protection cost; when conducting child inspection, a children's anti-radiation belt 3 with a width significantly smaller than that of an adult's anti-radiation belt 3 can be selected, and a first connecting rod 41 of a matching length can be selected to form a children's radiation protection area, and the anti-radiation belt 3 at different positions can be removed according to different inspection areas.
