[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0026] like Figure 1-Figure 4 As shown,

[0027] The present invention provides a medical radiation protection structure comprising a plurality of vertically foldable protective components. Specifically, the plurality of protective components are vertically connected by a flexible member 2. In this embodiment, the flexible member 2 is a flexible connecting sheet made of lead material, which is formed into lead foil and lead wire. The flexible improvement of the lead material is achieved by overlapping the wire mesh, and the structure has excellent bending properties. The plurality of protective components can be fixedly connected in the horizontal direction by bolts or the like, or can be detachably connected by plugging. When fixedly connected by bolts, holes need to be punched in the protective components. When plugged in, one end of the upper and lower parts of the protective components needs to protrude, and the other end needs to have a groove that matches the protrusion to facilitate plugging. The bolts and plugging of the protective components are all existing technologies, so they will not be described in detail. In this embodiment, the connection is fixed by bolts.

[0028] In this embodiment, the protection assembly includes a protection plate 11 and a protection plate 2 12 which are embedded into a whole.

[0029] The first protective plate 11 has a hollow chamber 1101 , and the second protective plate 12 has a protrusion 1201 that fits with the chamber 1101 .

[0030] In this embodiment, the material of the protective plate 11 and the protective plate 2 12 can be lead plate, or other materials with radiation blocking function.

[0031] Nuclear radiation sensors are installed on the protective plate 11. They measure radiation intensity by sensing alpha particles, beta particles, gamma rays, and neutron rays released during the decay of radioactive isotopes. The number of nuclear radiation sensors can be adjusted according to actual usage needs, and they can be evenly distributed on multiple protective plates 11 without any blind spots.

[0032] A feed pipe 3 is provided above the protective plate 11. The feed pipe 3 is a hose. The material is not limited and can be made of rubber so that it can be folded and stored when not in use.

[0033] A feed port is provided on the protective plate 11 so as to be connected to the feed pipe 3.

[0034] When the radiation intensity exceeds the set threshold, that is, exceeds the radiation protection intensity of the protective plate 11, the capsule 5 injects the magnetic fluid into the feeding pipe 3 through the electric pump, and the magnetic fluid flows into the capsule 5.

[0035] The magnetic fluid filled in this embodiment contains surface-modified bismuth, tungsten, or barium sulfate particles. Ultrasonic dispersion and surfactant treatment ensure that the radiation-proof material is evenly suspended in the magnetic fluid. The filling material of the medical radiation-proof magnetic fluid provided by the present invention can be comprehensively selected according to the radiation type such as neutrons and gamma rays, the usage scenario such as interventional surgery, imaging diagnosis, and biosafety requirements, so as to achieve a balance between efficient protection and clinical safety.

[0036] A stop valve is provided at the connection between the protective plate 11 and the feed pipe 3 to facilitate the control of the injection amount of the magnetic fluid.

[0037] In order to recycle the magnetic fluid in the protective plate 11 after use, a discharge pipe 4 is provided at the bottom of the protective plate 11. Accordingly, a discharge port is provided at the bottom of the protective plate 11 to facilitate the recovery of the magnetic fluid after use. The magnetic fluid is recovered into the container. The container for holding the magnetic fluid is prior art and will not be described in detail in the present invention.

[0038] A stop valve is also provided at the connection between the protective plate 11 and the discharge pipe 4 to facilitate control of whether the magnetic fluid flows out.

[0039] A movable groove 14 is provided on the contact surface of the protective plate 11 with the protective plate 2 12. A movable structure is provided in the movable groove 14. The movable structure includes a push rod 15 and a return spring 16. One end of the return spring 16 is fixedly connected to the movable groove 14, and the other end is fixedly connected to the push rod 15. The other end of the push rod 15 is fixedly connected to the protective plate 2 12. When the magnetic fluid is recovered, the protective plate 2 12 moves toward the protective plate 11 under the action of the return spring 16 until it fits with the protective plate 11.

[0040] In order to ensure that the protective plate 11 and the protective plate 2 12 will not be easily separated when the medical radiation protection structure provided by the present invention is used or stored, the contact surface ends of the protective plate 11 and the protective plate 2 12 are inlaid with attractive magnetic blocks to improve the stability of the protective plate 11 and the protective plate 2 12 after they are fitted together. No magnetic blocks are set on the hollow chamber 1101 and the protrusion 1201, and the size of the magnetic blocks is not limited, as long as the protective plate 11 and the protective plate 2 12 can be tightly fitted together, and when the overall structure tilts downward, the protective plate 2 12 and the protective plate 1 11 will not be easily separated. Example

[0041] like Figure 2-Figure 5 As shown:

[0042] Considering that magnetic fluid may leak in chamber 1101, especially when protective plate 2 12 slides outward, it is difficult to completely seal the gap between protective plate 2 12 and protective plate 1 11. Therefore, the present invention further improves the above embodiment, specifically:

[0043] A capsule 5 is provided in the chamber 1101 , and both the upper and lower parts of the capsule 5 are opened. The upper opening of the capsule 5 is connected to the feed pipe 3 , and the lower opening of the capsule 5 is connected to the discharge pipe 4 , so as to facilitate the injection and discharge of the magnetic fluid.

[0044] After the capsule 5 is injected with magnetic fluid, its volume is fully expanded to 3-5 times of its original volume.

[0045] The bladder body 5 is an elastic bladder, and the material thereof is not limited, and can be made of rubber.

[0046] Considering that magnetic fluid remains a fluid in the absence of a magnetic field, the inner wall of chamber 1101 is provided with electromagnetic coils 13. Multiple groups of electromagnetic coils 13 are arranged horizontally. These groups can be individually controlled to adjust the phase or intensity of each coil and compensate for coupling effects. Even if one group of electromagnetic coils 13 fails, the remaining coils 13 remain operational, enabling gradient control and solidification of the magnetic fluid when powered. Example

[0047] Considering that after the medical radiation protection structure provided by the present invention is used, the magnetic fluid is discharged from the capsule 5 and some residual magnetic fluid remains, therefore, this embodiment is further improved on the basis of the above embodiment, specifically:

[0048] like Figure 2-Figure 6 As shown:

[0049] A scraping mechanism is provided on the protrusion 1201 and slides up and down along the chamber 1101. The scraping mechanism includes a scraper 61, a slide rod 62 and a connecting rod 63. The corresponding chamber 1101 is provided with a slide groove 64 for the slide rod 62 to slide. The slide groove 64 is inclined from the outside to the inside so that when the scraping mechanism slides downward, it gradually squeezes the capsule 5 inward to squeeze out the residual magnetic fluid in the capsule 5.

[0050] A vertically arranged electromagnetic coil 13 is also provided on the scraper 61. When the scraper 61 slides downward, the electromagnetic coil 13 is energized to attract the magnetic fluid to flow downward.

[0051] Magnetic fluids consist of nanoparticles suspended in a carrier liquid and are highly sensitive to magnetic fields. Magnetic fields can induce the particles to align along magnetic field lines, forming chain-like structures. This can increase apparent viscosity, but flow can also be guided by directional magnetic fields. This requires that the direction of the magnetic force align with the direction of flow.

[0052] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
