Description

Technical Field

[0001] This invention relates to the field of radiology, and more particularly to an adjustable radiation shielding device for radiology. Background Technology

[0002] The radiation emitted by the radiation source can damage cells, tissues, and even cell nuclei, causing varying degrees of harm to the human body. When patients are examined in other parts of their body, radiation protection cloth is used to wrap the area to protect their gonads from radiation damage.

[0003] Medical staff lay down a radiation-proof cloth on the bed and then roll and fix the cloth after the patient is in place to cover the gonads and prevent radiation exposure.

[0004] The above methods increase the workload of medical staff, and the fact that each patient is wrapped in the same radiation protection cloth will affect the cleanliness of the cloth.

[0005] To address the above issues, we propose an adjustable radiation shielding device for radiology departments. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides an adjustable radiation shielding device for radiology departments. A radiation shielding cloth is used to cover the patient, preventing direct radiation exposure. A displacement winding section, assisted by an auxiliary rotating rail, rotates to wind up the radiation shielding cloth and moves it to the end of the bed. A locking mechanism connects the fixing section and the displacement winding section. Driven by an external power source, the device rotates to the lower end of the bed for storage.

[0007] The present invention provides an adjustable radiation shielding device for radiology, including a bed body with a radiation shielding mechanism on the bed body;

[0008] The radiation protection mechanism includes a fixing part that extends to both sides of the bed and is rotatably connected to the bed. The fixing part includes a fixed vertical plate, a rotating shaft, and a fixed roller. The rotating shaft is rotatably connected to the bed. The fixed vertical plate is rotatably mounted on the side of the bed via the rotating shaft. The fixed roller is fixedly connected to the fixed vertical plate. A stop block is fixed to the side of the bed to restrict the rotation of the fixed vertical plate.

[0009] The radiation protection mechanism also includes a displacement winding section, which extends to both sides of the bed. The displacement winding section includes a winding roller, a rotating rod, a rotating plate, and a pulley mechanism. A sliding block is slidably connected to the bed, and the sliding block is rotatably connected to the rotating rod. The winding roller is located above the bed. One end of the pulley mechanism is connected to the rotating rod, and the other end is connected to the winding roller. One end of the rotating plate is fixed to the rotating rod, and the other end is rotatably connected to the winding roller. Radiation protection cloth is fixed to the fixed roller, and the other end of the radiation protection cloth is wound around the winding roller. The pulley mechanism includes a pulley and a connecting belt. There are two pulleys, each with an annular groove on its surface. They are coaxially fixed to the winding roller and the rotating rod, respectively. The connecting belt connects the two pulleys and presses against the annular groove. The pulley on the rotating rod is pressed against the auxiliary rotating rail. The center of the rotating shaft and the rotating rod are on the same horizontal plane.

[0010] The radiation protection mechanism also includes an auxiliary rotating rail, which is fixed to the lower end of the bed and extends to its side, pressing against the displacement winding part.

[0011] The radiation protection mechanism also includes a locking mechanism. One end of the locking mechanism is located on the fixed part, and the other end is located on the displacement and winding part. The locking mechanism includes a locking plate and a locking sleeve. The locking sleeve is fixed to the rotating shaft, and one end of the locking plate is fixed to the rotating rod, while the other end is movably inserted into the locking sleeve.

[0012] Beneficial effects of the present invention: The present invention provides an adjustable radiation shielding device for radiology departments:

[0013] 1. Use radiation-proof cloth to shield the patient's surface to avoid direct exposure to radiation;

[0014] Second, the sliding block and displacement winding part are moved by an external drive mechanism, so that the displacement winding part can move and wind up the radiation cloth, making it convenient for the next patient to lie down on the bed.

[0015] 3. When the displacement winding part moves to the side end of the bed, the locking plate is inserted into the locking sleeve. The external power mechanism can simultaneously drive the fixing part and the displacement winding part to rotate synchronously to the lower end of the bed for storage.

[0016] Fourth, by setting a rotating plate and fixing it to the rotating rod, the take-up roller is supported, and when the take-up roller rotates to the upper end of the bed for displacement, the stability of the take-up roller is ensured, and the take-up roller is prevented from rotating around the rotating rod.

[0032] The radiation protection mechanism 2 includes a displacement winding section 4, which extends to both sides of the bed 1. The displacement winding section 4 includes a winding roller 12, a rotating rod 8, a rotating plate 13, and a pulley mechanism 14. A sliding block 9 is slidably connected to the bed 1, and the sliding block 9 is rotatably connected to the rotating rod 8. The winding roller 12 is located above the bed 1. One end of the pulley mechanism 14 is connected to the rotating rod 8, and the other end is connected to the winding roller 12. One end of the rotating plate 13 is fixed to the rotating rod 8, and the other end is rotatably connected to the winding roller 12. A radiation shielding cloth 19 is fixedly attached to the fixed roller 11. The other end of the radiation shielding cloth 19 is wound around the take-up roller 12. The pulley mechanism 14 includes pulleys 15 and connecting belts 16. There are two pulleys 15, each with an annular groove on its surface. They are coaxially fixed to the take-up roller 12 and the rotating rod 8, respectively. The connecting belt 16 connects the two pulleys 15 and presses against the annular grooves. The pulleys 15 on the rotating rod 8 are pressed against the auxiliary rotating rail 5. The center of the rotating shaft 7 and the center of the rotating rod 8 are on the same horizontal plane.

[0033] The radiation protection mechanism 2 also includes an auxiliary rotating rail 5, which is fixed to the lower end of the bed body 1 and extends to its side, pressing against the displacement winding part 4.

[0034] The radiation protection mechanism 2 also includes a locking mechanism 6. One end of the locking mechanism 6 is located on the fixed part 3, and the other end is located on the displacement winding part 4. The locking mechanism 6 includes a locking plate 17 and a locking sleeve 18. The locking sleeve 18 is fixedly connected to the rotating shaft 7. One end of the locking plate 17 is fixedly connected to the rotating rod 8, and the other end is movably inserted into the locking sleeve 18.

[0035] The bed 1 is provided with a drive mechanism for moving the sliding block 9. The drive mechanism includes a drive motor 21 and a threaded rod 22. The drive motor 21 is fixed to the side end of the bed 1, and the threaded rod 22 is fixed to the output end of the drive motor 21. The threaded rod 22 is threadedly connected to the sliding block 9.

[0036] The sliding block 9 is equipped with a power mechanism that drives the rotating rod 8 to rotate. The power mechanism includes a second drive motor 23, a conveyor wheel 24, and a conveyor belt 25. The second drive motor 23 is fixedly connected to the sliding block 9.

The conveyor belt 25 connects the two conveyor wheels 24.

[0037] The principle of this invention:

[0038] When in use, the patient lies on the bed, the drive motor 23 starts, and drives the conveyor wheel 24 on it to rotate. Through the conveyor belt 25, it drives another conveyor wheel 24 to rotate, which drives the rotating rod 8 to rotate. Through the locking mechanism 6, it drives the rotating shaft 7 to rotate, which drives the fixed vertical plate 10 to rotate until it is blocked by the stop block 20. When blocked, the fixed vertical plate 10 is in an inclined state. When the fixed vertical plate 10 rotates, it drives the fixed roller 11 to flip from the lower end of the bed 1 to the upper end of the bed 1. When the rotating rod 8 rotates, it drives the rotating plate 13 to rotate, which drives the winding roller 12 to rotate around the rotating rod 8, so that the winding roller 12 and the fixed roller 11 rotate synchronously from the lower end of the bed 1 to the upper end of the bed 1.

[0039] After flipping, drive motor 23 stops and drive motor 21 starts, driving threaded rod 22 to rotate, causing sliding block 9 to slide, driving rotating rod 8 to move, and driving pulley 15 to move until it contacts the upper surface of auxiliary rotating rail 5. Pulley 15 continues to move, and due to the friction between auxiliary rotating rail 5 and pulley 15, pulley 15 rotates. Through connecting belt 16, another pulley 15 rotates, causing take-up roller 12 to rotate while moving, moving and unfolding the rolled-up radiation-proof cloth 19 to cover the patient's surface.

[0040] After use, the anti-radiation cloth 19 is rolled up by reversing the start of drive motor 23, and the anti-radiation cloth 19 is flipped to the bottom of bed 1 for storage by reversing the start of drive motor 21.
