Description

Technical Field

[0001] This utility model relates to the field of operating room technology, specifically to a radiation-proof operating room. Background Technology

[0002] Radiation-protected operating rooms play a crucial role in the medical field. They provide a sterile and clean environment for surgery, significantly reducing postoperative infection rates, improving surgical quality, and accelerating patient recovery. With advancements in medical technology, the medical equipment they are equipped with is constantly increasing, especially with the addition of CT scanners. While CT scanners are highly effective in medical procedures, they carry a certain radiation dose. During operation, personnel inside can mitigate this by wearing protective clothing. Radiation-protected operating rooms are primarily used for surgeries involving the treatment or diagnosis of radioactive materials, such as radiotherapy, nuclear medicine procedures, and interventional radiology. However, if the operating room structure has weak points or inadequate protection, radiation leaks can easily occur, threatening the lives of medical staff and patients outside the operating room and increasing their risk of cancer.

[0003] Existing radiation-proof operating rooms primarily achieve radiation protection through lead doors. This involves installing a sliding base on the lead door within a floor-mounted track, and a movable block on the top of the lead door is threaded onto a lead screw. A motor drives the lead screw to rotate forward or reverse, moving the lead door left or right. By installing a sealing plate on one outer wall of the lead door, which is then inserted into a slot on the front of the operating room's door frame, the operating room is effectively sealed, reducing the possibility of radiation seeping through the door gaps.

[0004] However, existing radiation-proof operating rooms only focus on protecting the opening and closing of the door. The entire operating room also includes the walls, ceiling, and floor, totaling six surfaces, making it impossible to provide comprehensive protection. The lack of radiation-proof structure on the inner walls of the operating room can easily affect the health and safety of people outside the operating room, as well as the health and safety of people on the floor above or below.

[0005] Existing radiation protection operating rooms do not take into account sound insulation and fire protection functions. Utility Model Content

[0006] In view of the technical problems existing in the prior art, the purpose of this utility model is to provide a radiation-proof operating room, in which the inner wall of the operating room is protected against radiation in all directions, the fireproof rock wool layer has fireproof function, and the gypsum board has sound insulation effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A radiation-proof operating room includes a wall radiation-proof structure, a floor radiation-proof structure, and the wall radiation-proof structure, the floor radiation-proof structure, and the floor radiation-proof structure of the upper floor enclose the operating room; the wall radiation-proof structure includes a keel frame, a radiation-proof lead plate, a fireproof rock wool layer, and a gypsum board, with the keel frame forming the main body of the wall, and the inner surface of the keel frame being sequentially connected to the radiation-proof lead plate, the fireproof rock wool layer, and the gypsum board; the floor radiation-proof structure includes a floor slab and a barium sulfate cement layer, with the barium sulfate cement layer set on the floor slab.

[0009] As a preferred option, the wall radiation shielding structure also includes lead shielding screws and lead sheets. The radiation shielding lead plate is fixed to the keel frame by the lead shielding screws, and the lead sheets are tightly attached to the radiation shielding lead plate.

[0011] As a preferred option, the wall radiation shielding structure also includes a resin board, with the inner surface of the gypsum board connected to the resin board.

[0012] As a preferred embodiment, the outer side of the keel frame is connected to gypsum board and resin board in sequence.

[0013] As an alternative, the ground radiation shielding structure also includes a wire mesh, which is laid between the top surface of the floor slab and the barium sulfate cement layer.

[0014] As a preferred option, the ground radiation shielding structure also includes a cement mortar leveling layer, which is laid on top of the barium sulfate cement layer.

[0015] As a preferred embodiment, the operating room also includes a suspended ceiling and an air purification system. The suspended ceiling is located at the top of the operating room, and the air purification system is installed between the suspended ceiling and the floor slab. The air purification system includes an air inlet device and an air outlet device. The air inlet device includes an air inlet duct and a static pressure box. The air inlet duct is connected to the static pressure box, which is installed on the top surface of the suspended ceiling. The static pressure box has a downward-blowing air outlet. An exterior wall is provided on the outside of the floor slab and outside the operating room. The air inlet end of the air inlet duct is installed on the exterior wall. The air outlet device includes an air outlet duct and an air outlet pump. The air outlet duct is connected to the air outlet pump, which is fixed to the bottom surface of the floor slab. The air outlet end of the air outlet duct is installed on the exterior wall, and the air inlet end of the air outlet duct is installed on the suspended ceiling.

[0016] As a preferred option, the static pressure box is equipped with a high-efficiency filter, and the air inlet end of the air inlet pipe is equipped with a medium-efficiency filter.

[0036] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] like Figures 1 to 7 As shown, a radiation-proof operating room includes a wall radiation-proof structure 2, a floor radiation-proof structure 3, and the wall radiation-proof structure 2, the floor radiation-proof structure 3, and the floor radiation-proof structure 3 on the upper floor enclose the operating room 1. The wall radiation-proof structure 2 includes a keel frame, a radiation-proof lead plate 5, a fireproof rock wool layer 6, and a gypsum board 7. The keel frame is the main body of the wall, and the inner surface of the keel frame is sequentially connected to the radiation-proof lead plate 5, the fireproof rock wool layer 6, and the gypsum board 7. The floor radiation-proof structure 3 includes a floor slab 19 and a barium sulfate cement layer 8, with the barium sulfate cement layer 8 installed on the floor slab 19. By sequentially installing the radiation-proof lead plate 5, the fireproof rock wool layer 6, and the gypsum board 7 within the keel frame, radiation leakage is effectively prevented. Simultaneously, the fireproof rock wool layer 6 has fireproof properties, and the gypsum board 7 provides sound insulation.

[0038] The fireproof rock wool layer 6 includes a rock wool core material layer and two moisture-proof layers. The two moisture-proof layers are respectively connected to the inner and outer surfaces of the rock wool core material layer to prevent the rock wool core material layer from getting damp.

[0039] like Figure 4 As shown, the wall radiation shielding structure 2 also includes lead shielding screws 9 and lead sheets 10. The radiation shielding lead plate 5 is fixed to the keel frame by the lead shielding screws 9. The lead sheets 10 are tightly attached to the radiation shielding lead plate 5. The lead shielding screws 9 pass through both the lead sheets 10 and the radiation shielding lead plate 5 and are then screwed into the keel frame. The screw head of the lead shielding screw 9 is covered by the bent lead sheets 10. The screw head of the lead shielding screw 9 and the lead sheets 10 are located inside the fireproof rock wool layer 6. This utility model cleverly sets up a bendable lead sheet 10. First, the lead sheet 10 is laid flat on the radiation shielding lead plate 5. The lead shielding screw 9 passes through the lead sheets 10. After the lead shielding screw 9 passes through the radiation shielding lead plate 5 and is screwed into the keel frame, the excess lead sheets 10 can be bent to cover the screw head of the lead shielding screw 9, further effectively preventing local radiation leakage.

[0040] like Figure 5 As shown, the radiation shielding lead plates 5 are spliced ​​along the surface of the keel frame, and the radiation shielding lead plates 5 are overlapped at the splicing points and fixed by lead shielding screws 9.

[0041] The keel frame includes multiple vertical keels 11 and multiple horizontal keels 12. The vertical keels 11 and multiple horizontal keels 12 are respectively spliced ​​to form a mesh frame. The horizontal keels 12 include long horizontal keels and short horizontal keels. On one side of the main wall, the long horizontal keel is the lowest horizontal keel 12. The long horizontal keel is fixed to the ground radiation shielding structure 3 by the first expansion bolt 20. The first expansion bolt 20 usually extends into the floor slab 19. The multiple vertical keels 11 are fixed to the long horizontal keels. The multiple vertical keels 11 are along the length of the long horizontal keel. The vertical joists 11 are arranged at intervals along a 12-degree axis. Their tops are fixedly connected to the ceiling of the operating room via connecting angle steel 21. The connecting angle steel 21 is L-shaped; one side of the connecting angle steel 21 is fixed to the vertical joist 11 with bolts, and the other side is fixed to the ceiling slab 19 with second expansion bolts 4. Short horizontal joists are installed between adjacent vertical joists 11, and so on, forming the four sides of the wall structure. Multiple lead-shielded screws 9 are correspondingly installed at the positions of the horizontal joists 12. This ensures the stability of the wall and ease of installation.

[0042] The wall radiation shielding structure 2 also includes a resin board 13, with the inner surface of the gypsum board 7 connected to the resin board 13. The resin board 13 has excellent chemical stability and antibacterial properties, providing an easy-to-clean, antibacterial surface that helps maintain a sterile environment in the operating room 1.

[0043] The outer side of the keel frame is connected to plasterboard 7 and resin board 13 in sequence. This further enhances the sterile environment and sound insulation of operating room 1.

[0044] The ground radiation shielding structure 3 also includes a wire mesh 14, which is laid between the top surface of the floor slab 19 and the barium sulfate cement layer 8. Preferably, the wire mesh 14 is galvanized; the wire mesh 14 can prevent cracking, enhance the overall compressive strength and durability of the ground, and reduce the risk of damage due to long-term use.

[0045] The ground radiation shielding structure 3 also includes a cement mortar leveling layer 15, which is laid on top of the barium sulfate cement layer 8. The cement mortar leveling layer 15 makes the floor inside the operating room 1 smoother.

[0046] The radiation protection structure on the top of the operating room of this utility model is the ground radiation protection structure 3 of the floor above. There is no need to do radiation protection treatment under the ceiling in the operating room 1. This solves the problems of high construction difficulty in setting up a radiation protection structure on the ceiling in the operating room 1, easy detachment of the protective layer of the radiation protection structure due to gravity, and inconvenience caused by ceiling and pipeline obstruction if repair is required.

[0047] like Figure 6 As shown, the operating room 1 also includes a suspended ceiling 23 and an air purification system; the suspended ceiling 23 is located at the top of the operating room 1, and the air purification system is installed between the suspended ceiling 23 and the floor slab 19. The air purification system includes an air inlet device and an air outlet device. The air inlet device includes an air inlet pipe 16 and a static pressure box 17. The air inlet pipe 16 is connected to the static pressure box 17, which is installed on the top surface of the suspended ceiling 23. The static pressure box 17 has a downward-blowing air outlet. The outer side of the floor slab 19 and located outside the operating room are... An exterior wall 22 is provided. The air inlet end of the air inlet duct 16 passes through the wall radiation shielding structure 2 and is installed on the exterior wall 22. The air outlet device includes an air pump and an air outlet duct 18. The air pump is fixedly installed on the bottom surface of the floor slab and is connected to the air outlet duct 18. The air pump provides power to the air outlet duct 18 to ensure that air is drawn out of the operating room 1 through the air outlet duct 18. The air outlet end of the air outlet duct 18 passes through the wall radiation shielding structure and is installed on the exterior wall 22. The air inlet end of the air outlet duct 18 is installed on the ceiling 23. The air purification system enables air circulation in the operating room 1. It is worth noting that the wall radiation shielding structure 2 is penetrated by the air inlet duct 16 and the air outlet duct 18, therefore the wall radiation shielding structure 2 has a lateral penetration point. However, the radiation direction of the radiation source 24 in the operating room 1 is generally in the lateral and longitudinal directions (e.g., Figure 7 As shown), the radiation source 24 is located below the ceiling 23. Therefore, the radiation direction of the radiation source 24 will not radiate to the outside of the wall radiation protection structure 2 through the penetration point. Therefore, there will be no radiation leakage in this utility model.

[0048] The static pressure chamber 17 is equipped with a high-efficiency filter, and the air inlet end of the air inlet duct 16 is equipped with a medium-efficiency filter. A high-efficiency filter is a filtration device capable of efficiently capturing fine particulate matter in the air, removing at least 99.97% of particles with a diameter of 0.3 micrometers. A medium-efficiency filter is a filtration device between a pre-filter and a high-efficiency filter, mainly used to capture larger particles in the air, such as dust, pollen, and fibers. Its filtration efficiency is typically between 50% and 95%, depending on the materials and design used. The high-efficiency and medium-efficiency filters ensure that the air entering the operating room 1 undergoes multi-stage filtration, effectively removing airborne particulate matter and microorganisms, thus guaranteeing the cleanliness of the surgical environment.

[0049] The wall radiation shielding structure 2 and floor radiation shielding structure 3 of Operating Room 1 significantly improve radiation shielding performance through the comprehensive application of multiple layers and materials, while also offering excellent ease of construction and a long service life. These improvements make Operating Room 1 more reliable and efficient in practical applications, meeting the high-standard protective facilities required in modern medical environments. Operating Room 1 can significantly reduce the risk of radiation leakage and maintain a high level of air cleanliness, providing a safer and more comfortable surgical environment for medical staff and patients.

[0050] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
