Description

Technical Field

[0001] The present application relates to the field of radiation protection technology, for example, to an isolation door leaf and a sliding door for a radiation room. Background Art

[0002] At present, X-rays are widely used in medical and industrial production. For example, CT machines. X-rays can produce ionization effects when they pass through matter. For example, X-rays entering the human body will produce ionization effects, which can easily cause biological changes in the human body and cause diseases, that is, biological effects. Therefore, before using X-rays, shielding and protection work needs to be done well.

[0003] Radiology rooms (such as CT rooms) are generally equipped with suspended electric sliding doors to reduce radiation leakage. In order to achieve smooth sliding of the sliding door, a gap is left between the bottom of the sliding door and the ground. When the CT machine performs radiation scanning, the gap between the sliding door and the ground can easily cause radiation to leak out, which in turn causes the radiation dose near the gap to fail to meet the protection requirements.

[0004] In the related art, a protective sinking mechanism is provided, comprising: a base surface, a carrier part, a guide wheel, a connecting rod mechanism and a sinking bar assembly. A gap is formed between the carrier part and the base surface, and the connecting rod mechanism and the sinking bar assembly are both arranged on the carrier part. The guide wheel is movably in contact with one end of the connecting rod mechanism, and the other end of the connecting rod mechanism is used to drive the sinking bar assembly to be arranged close to or away from the base surface, so as to realize radiation protection of the gap between the lower edge of the door body and the ground.

[0005] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0006] In the related art, the guide wheel pushes the connecting rod mechanism to drive the sinking bar assembly close to or away from the foundation surface, which can play a certain protective role. However, due to the structural limitations of the connecting rod mechanism and the sinking bar assembly, there is still a gap between the sinking bar assembly and the foundation surface, resulting in radiation leakage and unsatisfactory protective effect. In addition, the sinking bar assembly needs to be driven by the connecting rod mechanism to move, which has a complex structure and is not easy to repair.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

These terms are mainly intended to better describe the embodiments of the present disclosure and their embodiments, and are not intended to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction. Moreover, in addition to being used to indicate directions or positional relationships, some of the above terms may also be used to indicate other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in certain circumstances. For those of ordinary skill in the art, the specific meanings of these terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0049] In addition, the terms "disposed", "connected", and "fixed" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components.

[0050] Unless otherwise stated, the term "plurality" means two or more.

[0051] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0052] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0054] X-rays have a very short wavelength and strong penetrating power, and can penetrate materials of different densities. After X-rays are incident on a material, they are absorbed, penetrated, and scattered, causing them to attenuate. For a CT machine, after X-rays are emitted from the focus of the tube, they are limited by the collimation and filtering system, and only useful beams within a limited width are directly affected, passing through the patient and bed and irradiating the detector. The rest of the X-rays are scattered through the surface of objects to the surroundings of the CT machine in the machine room. After the X-rays are emitted, the farther away from the focus, the greater the attenuation.

[0055] Since the wavelength of X-rays is very short, they can penetrate materials with large gaps between atoms. Therefore, the penetration ability of X-rays is related to the density of the material. When performing shielding and protection work, it is necessary to choose materials with high density as shielding and protection materials, such as lead.

[0056] GBZ 130-2020 Radiation Diagnosis Radiation Protection Requirements states that the radiation shielding protection of the machine room should meet the requirement that the dose equivalent rate of the surrounding radiation outside the machine room is less than or equal to 2.5μSv / h. At the same time, the protection inspection of the X-ray equipment room should focus on the local shielding and gaps of the focus points on the basis of the inspection. The focus points should include: four walls, floors, ceilings, machine room doors, operating room doors, observation windows, lighting windows / windows, film transmission boxes, pipeline openings, staff operating positions, etc. The selection of points should be representative.

[0057] In the prior art, the walls, floors, and ceilings of the radiation room (the room where the radiation source is placed) can be decorated once to meet the protection requirements. However, there are many problems with the isolation protection of local locations such as doors and windows. For example, a slide rail is set on the ground for the sliding of the protective door. The setting of the slide rail causes the ground to be uneven, affecting the entry and exit of patients, medical beds, etc. It is also easy to harbor dirt and grime, which is not conducive to maintaining the sanitation level inside and outside the operating room. If there is no slide rail on the ground, in order to ensure the smooth sliding of the protective door (for example, a sliding door), a gap is left between the bottom end of the protective door and the ground, which can easily lead to the leakage of radiation rays.

[0058] With the advancement of medical technology, hybrid operating rooms have been developed. Hybrid operating rooms include DSA (Digital Subtraction Angiography) operating rooms and sliding CT rooms. The DSA operating room is connected to the sliding CT room, and a protective door is set between the DSA operating room and the sliding CT room. When performing radiation scanning in the sliding CT room, it is isolated from the DSA operating room by the protective door. For example, the protective door adopts a suspended electric sliding door. There is a gap between the bottom of the sliding door and the ground, resulting in the radiation dose near the gap in the DSA operating room not meeting the protection requirements when the sliding CT is working.

[0059] In the prior art, the sliding doors that can be used in the radiology room mostly adopt the top-hung sliding door structure, such as single-leaf door, double-joint sliding door, double-joint single-side sliding door or triple-joint door, etc. Moreover, there are overlapping parts between door leaves and between door leaves and wall.

[0060] Combination Figures 1 to 8 As shown, the embodiment of the present disclosure provides an isolation door leaf 10 for a radiation room. The isolation door leaf 10 for a radiation room includes a door body 20 and an isolation portion 30. The isolation portion 30 is disposed on the door body 20, and the isolation portion 30 can move relative to the door body 20 under the action of gravity to cover the gap 50 between the door body 20 and the base surface 60.

[0061] The isolation door leaf 10 for a radiation room provided in the embodiment of the present disclosure has an isolation portion 30 disposed on the door body 20, and the isolation portion 30 can move relative to the door body 20 under the action of gravity, so that the isolation portion 30 can block the gap 50 between the door body 20 and the base surface 60. The structure is simple, and can effectively reduce the amount of radiation leakage and improve the protection effect.

[0062] In this embodiment, the isolation door leaf 10 for the radiation room is suitable for a suspended electric sliding door, which can cover the gap 50 between the bottom of the door body 20 and the base surface 60 by providing a movable isolation part 30 on the door body 20 without damaging the continuous flatness of the base surface 60 .

[0063] It can be understood that when the isolation door leaf 10 is in the installed state, the base surface 60 is a plane located below the isolation door leaf 10. For example, the base surface 60 is the ground.

[0064] In this embodiment, the isolation portion 30 does not destroy the continuity and flatness of the base surface 60, which is conducive to the passage of equipment and the like, thereby improving ease of use.

[0065] In this embodiment, the isolation part 30 can be fitted with the base surface 60 under the action of gravity, which is convenient to use and maintain.

[0066] Optionally, the door body 20 is provided with a shielding protective material (eg, lead) for absorbing and scattering the rays directly emitted from the radiation source to the door body 20 to attenuate the rays.

[0067] In some embodiments, the door body 20 includes a first sliding structure extending in the gravity direction, and the isolation portion 30 includes a second sliding structure slidably matched with the first sliding structure.

[0068] In this embodiment, the first sliding structure of the door body 20 extends along the direction of gravity, and the second sliding structure of the isolation part 30 slides with the first sliding structure, that is, the second sliding structure can move relative to the first sliding structure along the direction of gravity. Through the sliding cooperation between the first sliding structure and the second sliding structure, the isolation part 30 can move relative to the door body 20 under the action of its own gravity, thereby enabling the isolation part 30 to cover the gap 50 between the door body 20 and the base surface 60.

[0069] Optionally, the first sliding structure adopts a slide rail, which extends along the gravity direction. The second sliding structure adopts a slider, which is slidably arranged on the slide rail.

[0070] In this embodiment, under the action of the gravity of the isolation part 30 itself, the slider can move along the slide rail to enable the isolation part 30 to move relative to the door body 20, thereby enabling the isolation part 30 to cover the gap 50 between the door body 20 and the base surface 60.

[0071] Combination Figure 1 as well as Figures 4 to 8 As shown, in some embodiments, the door body 20 defines an active cavity 21 having an opening in the gravity direction and the opening facing the base surface 60. The active cavity 21 is arranged along the width extension direction of the door body 20, and the isolation part 30 is partially embedded in the active cavity 21.

[0072] In this embodiment, the door body 20 defines an active cavity 21 having an opening in the direction of gravity and the opening is toward the base surface 60, that is, the door body 20 defines an active cavity 21 having an opening in the direction of gravity, and the opening of the active cavity 21 is toward the base surface 60. The active cavity 21 is arranged along the width extension direction of the door body 20, and the isolation part 30 is partially embedded in the active cavity 21, that is, the length direction of the isolation part 30 extends along the width extension direction of the door body 20, and the isolation part 30 is partially embedded in the active cavity 21 along the gravity direction, so that the isolation part 30 can move relative to the active cavity 21 under the action of its own gravity, and then the isolation part 30 can move relative to the door body 20 to cover the gap 50 between the door body 20 and the base surface 60.

[0073] In the disclosed embodiment, the door body 20 defines an active cavity 21 having an opening, which provides a movable space and facilitates the isolation portion 30 to move relative to the door body 20 under the action of its own gravity.

[0074] In some embodiments, in combination Figures 5 to 7 As shown, the door body 20 includes a door body 22 and a protection portion 23. The protection portion 23 is disposed at the bottom of the door body 22. The protection portion 23 defines an active cavity 21.

[0075] In this embodiment, the door body 20 includes a door body 22 and a protective portion 23, and the protective portion 23 defines an active cavity 21 to provide a movable space for the isolation portion 30. The protective portion 23 is arranged at the bottom of the door body 22, so that the isolation portion 30 can move up and down relative to the active cavity 21 to cover the gap 50 between the door body 20 and the base surface 60.

[0076] For example, the door body 20 can be obtained by modifying the protective door leaf in the prior art, and has a simple structure and is easy to manufacture, repair, and replace. Specifically, the protective portion 23 can be a structure with the same width, thickness, material, etc. as the protective door leaf in the prior art, and the protective portion 23 is connected to the bottom of the protective door leaf (door body), so that the door body 20 of the present application can be obtained.

[0077] It is understood that the connection method between the protection part 23 and the door body 22 is not limited and can be set as needed. For example, the protection part 23 and the door body 22 are connected by plugging. For another example, the protection part 23 and the door body 22 are connected by step docking.

[0078] Exemplary, combined Figure 5 As shown, a protrusion 24 is provided at the bottom of the door body 22, and a groove 25 corresponding to the protrusion 24 is provided at the top of the protective part 23. The protrusion 24 is plug-connected and fixed with the groove 25 to realize the connection between the protective part 23 and the door body 22, which is convenient for disassembly, assembly and maintenance.

[0079] Exemplary, combined Figure 6 As shown, the bottom of the door body 22 and the top of the protection part 23 are provided with corresponding step structures 26. The protection part 23 is docked with the step structure 26 of the door body 22 and fixed to realize the connection between the protection part 23 and the door body 22, which is convenient for disassembly and maintenance.

[0080] In some embodiments, when the protection portion 23 is disposed at the bottom of the door body 22 , a shielding protection material is disposed between the protection portion 23 and the door body 22 .

[0081] In this embodiment, a shielding protection material (eg, lead) is provided between the protection portion 23 and the door body 22 to improve the protection effect.

[0082] In some embodiments, in combination Figure 7 As shown, the door body 20 includes a door body 22 and a protection portion 23. The protection portion 23 is disposed on the side of the door body 22. Specifically, the protection portion 23 is disposed below the side of the door body 22. The protection portion 23 defines an active cavity 21.

[0083] In this embodiment, by setting the protective part 23 at the lower side of the door body 22, the isolation part 30 can be moved along the gravity direction relative to the active cavity 21, that is, the isolation part 30 can be moved up and down relative to the active cavity 21 to block the gap 50 between the door body 20 and the base surface 60.

[0084] Optionally, combined Figure 7 As shown, the protection part 23 is a shell structure. The protection part 23 is fixed below the side of the door body 22, and the protection part 23 and the outer surface of the door body 22 define an active cavity 21 with an opening.

[0085] In this embodiment, the protective portion 23 and a part of the outer surface of the door body 22 enclose a movable cavity 21 with an opening, so that the movement of the door body 20 can drive the isolation portion 30 to move.

[0086] Optionally, combined Figure 8 As shown, a movable cavity 21 is provided at the bottom of the door body 20 to install the isolation part 30 .

[0087] It is understandable that the door body 20 may also adopt an existing protective door leaf, and an active cavity 21 may be opened at the bottom of the protective door leaf, with the opening facing the base surface 60 , and the connecting plate 31 of the isolation part 30 extends into the active cavity 21 .

[0088] In actual use, along the width extension direction of the door body 20, the walls of the movable cavity 21 at both ends push the isolating portion 30, so that the push-pull movement of the door body 20 can drive the isolating portion 30 to move. In addition, due to the setting of the opening, the isolating portion 30 can freely move up and down according to the position of the base surface 60 and its own gravity to be close to the base surface 60.

[0089] It can be understood that any modification to the door body 20 will not affect the use of the isolation door leaf 10 as a sliding door.

[0090] Combination Figures 1 to 8 As shown, in some embodiments, the isolation portion 30 includes a connection plate 31 disposed on the door body 20 and a bottom plate 32 connected to the connection plate 31 and capable of contacting the base surface 60 .

[0091] In this embodiment, the isolation part 30 includes a connecting plate 31 and a bottom plate 32. The connecting plate 31 is arranged on the door body 20. The bottom plate 32 is connected to the connecting plate 31. The bottom plate 32 can contact the base surface 60. The connecting plate 31 can extend from the opening into the active cavity 21, so that the isolation part 30 is partially embedded in the active cavity 21, and the connecting plate 31 can slide out of the active cavity 21 under the action of the gravity of the isolation part 30 itself, with a simple structure and convenient maintenance.

[0092] In actual application, the bottom plate 32 is arranged on the side of the connecting plate 31 away from the active cavity 21, so that the bottom plate 32 can contact the base surface 60. Under the action of the gravity of the isolation part 30 itself, the connecting plate 31 can partially slide out of the active cavity 21, so that the bottom plate 32 moves toward the base surface 60, and the isolation part 30 is in contact with the base surface 60. Through the cooperation between the connecting plate 31 and the bottom plate 32, the gap 50 between the door body 20 and the base surface 60 is shielded, which effectively reduces the radiation leakage and improves the protection effect.

[0093] Optionally, the first sliding structure is disposed on the cavity wall of the active cavity 21. The second sliding structure is disposed on the connecting plate 31. When the isolation portion 30 moves relative to the door body 20, the second sliding structure moves relative to the first sliding structure.

[0094] In some embodiments, in combination Figures 3 to 8 As shown, along the thickness direction of the connecting plate 31, one side of the bottom plate 32 protrudes from the connecting plate 31. That is, the bottom plate 32 and the connecting plate 31 form an L-shaped structure.

[0095] In this embodiment, along the thickness direction of the connecting plate 31, one side of the bottom plate 32 protrudes from the connecting plate 31, which can increase the contact area between the isolation portion 30 and the base surface 60, improve the ability to block scattered rays, and enhance the isolation and protection effect.

[0096] In some embodiments, in combination Figure 1 and Figure 2 As shown, along the thickness direction of the connecting plate 31, both sides of the bottom plate 32 protrude from the connecting plate 31. That is, the bottom plate 32 and the connecting plate 31 form an inverted T-shaped structure or a "X"-shaped structure.

[0097] In this embodiment, along the thickness direction of the connecting plate 31, both sides of the bottom plate 32 protrude from the connecting plate 31, increasing the width of the fitting surface between the isolation portion 30 and the base surface 60, increasing the contact area between the isolation portion 30 and the base surface 60, and thereby improving the protective effect.

[0098] Exemplary, combined Figure 2 and Figure 3 As shown, the whole of the connecting plate 31 and the bottom plate 32 can be formed by bending a flat plate. The connecting plate 31 is formed by folding a part of the flat plate in half, and the bottom plate 32 is formed by bending the remaining part of the flat plate relative to the connecting plate 31 to form an L-shaped structure or a "X"-shaped structure.

[0099] Combination Figure 1 As shown, optionally, when the isolation door leaf 10 is in the installed state, the length of one side of the bottom plate 32 protruding from the connecting plate 31 is greater than 5 times the distance between the bottom of the door body 20 and the base surface 60 .

[0100] In this embodiment, combined with Figure 1 As shown, when the isolation door leaf 10 is in the installed state, a indicates the length of one side of the bottom plate 32 protruding from the connecting plate 31, and H indicates the distance between the bottom of the door body 20 and the base surface 60.

[0101] In this embodiment, when the isolation door leaf 10 is in the installed state, the length (a) of one side of the bottom plate 32 protruding from the connecting plate 31 is greater than 5 times the distance (H) between the bottom of the door body 20 and the base surface 60, thereby effectively blocking the rays at the position of the gap 50, reflecting or scattering the rays back, thereby improving the protection effect.

[0102] Combination Figure 1 As shown, in some embodiments, when the isolation door leaf 10 is in the installed state, the length of one side of the bottom plate 32 protruding from the connecting plate 31 is equal to 5 times the distance between the bottom of the door body 20 and the base surface 60 .

[0103] In this embodiment, when the isolation door leaf 10 is in the installed state, the length (a) of one side of the bottom plate 32 protruding from the connecting plate 31 is equal to 5 times the distance (H) between the bottom of the door body 20 and the base surface 60, thereby effectively blocking the rays at the position of the gap 50, reflecting or scattering the rays back, thereby improving the protection effect.

[0104] It can be understood that when the isolation door leaf 10 is applied to the sliding door 40, the specific design of the length (a) of one side of the bottom plate 32 protruding from the connecting plate 31 can achieve that the length (a) of one side of the bottom plate 32 protruding from the connecting plate 31 is greater than or equal to 5 times the distance (H) between the bottom of the door body 20 and the base surface 60, while also achieving smooth pushing and pulling of the sliding door 40.

[0105] In this embodiment, when one side of the bottom plate 32 protrudes from the connecting plate 31, the length (a) of the one side of the bottom plate 32 protruding from the connecting plate 31 is greater than or equal to 5 times the distance (H) between the bottom of the door body 20 and the base surface 60. Figure 1 As shown, when both sides of the bottom plate 32 protrude from the connecting plate 31 , only the length (a) of one side protruding from the connecting plate 31 is greater than or equal to 5 times the distance (H) between the bottom of the door body 20 and the base surface 60 .

[0106] It can be understood that the thickness of the connecting plate 31 and the thickness of the bottom plate 32 are not limited and can be designed according to needs.

[0107] In some embodiments, the connecting plate 31 and the bottom plate 32 are both made of shielding and protective materials.

[0108] In this embodiment, the connecting plate 31 and the bottom plate 32 made of shielding and protective materials can absorb and scatter the radiation to achieve a protective effect.

[0109] It is understood that the specific type of shielding protective material is not limited, for example, lead.

[0110] Combination Figures 1 to 3 As shown, optionally, an arc transition is provided at the connection between the bottom plate 32 and the connecting plate 31 .

[0111] Combination Figures 1 to 3 As shown, in some embodiments, the isolation portion 30 further includes a protective shell 33 and a roller 34. The protective shell 33 is disposed on the outer side of the connecting plate 31. The roller 34 is disposed on the protective shell 33, and the roller 34 is located at the end of the connecting plate 31 in the width extension direction of the door body 20. The roller 34 is supported on the base surface 60.

[0112] In this embodiment, a protective shell 33 is provided on the outside of the connecting plate 31 to protect the connecting plate 31 and reduce the wear of the connecting plate 31 when it moves up and down in the movable cavity 21 and moves left and right with the door body 20.

[0113] In this embodiment, a roller 34 is provided at the end of the protective shell 33 , and the roller 34 is supported on the base surface 60 , so that the isolation part 30 can move left and right with the door body 20 , thereby improving the smoothness of the movement of the isolation part 30 with the door body 20 .

[0114] Optionally, rollers 34 are provided at the ends of both ends of the protective shell 33 along the moving direction of the door body 20 to improve the smoothness of the movement of the isolation part 30 along with the door body 20 .

[0115] Combination Figure 3 As shown, optionally, along the height direction of the door body 20 , the position of the protective shell 33 corresponding to the roller 34 protrudes downward to be used for installing the supporting structure of the roller 34 .

[0116] It is understandable that the supporting structure of the roller 34 is not limited, for example, the supporting structure is a rotating shaft.

[0117] Combination Figure 3 As shown, in some embodiments, the connecting plate 31 is provided with an escape opening 35. The escape opening 35 corresponds to the position of the roller 34. The roller 34 is located in the escape opening 35. The bottom plate 32 blocks the roller 34 in the width extension direction of the door body 20.

[0118] In this embodiment, the installation of the roller 34 is avoided through the avoidance opening 35 .

[0119] Exemplary, combined Fig.12As shown, when the isolation door leaf 10 for the radiation room is used as a suspended electric sliding door, there are overlapping parts between the isolation door leaf 10 and between the isolation door leaf 10 and the wall. The roller 34 is arranged at the end of the protective shell 33, that is, when the sliding door is in a closed state, the roller 34 is located at the overlapping part. In addition, the door body 20 is provided with shielding protection material, which can realize the protection of the position where the roller 34 is located.

[0120] Combination Figure 2 and Figure 3 As shown, in some embodiments, the isolation portion 30 further includes a shaping plate 36. The shaping plate 36 is disposed on a side of the bottom plate 32 away from the base surface 60, and the shaping plate 36 is connected to the connecting plate 31 to maintain the geometric configuration of the connecting plate 31 and the bottom plate 32.

[0121] In this embodiment, the shaping plate 36 is disposed between the connecting plate 31 and the protective shell 33, and the shaping plate 36 is also disposed on the side of the bottom plate 32 away from the base surface 60. The shaping plate 36 can stably fix the connecting plate 31 in the protective shell 33 to achieve the integrity of the isolation portion 30, and can also protect the surfaces of the connecting plate 31 and the bottom plate 32 to maintain the geometric configuration of the connecting plate 31 and the bottom plate 32.

[0122] Optionally, a shielding protective material (eg, lead) is disposed between the surface of the bottom plate 32 facing the connecting plate 31 and the shaping plate 36 to improve the protective effect.

[0123] Combination Figure 2 and Figure 3 As shown, in some embodiments, the isolation portion 30 further includes a protective layer 37. The protective layer 37 is disposed on a side of the bottom plate 32 close to the base surface 60.

[0124] In this embodiment, the protective layer 37 can reduce the sliding friction between the bottom plate 32 and the base surface 60, reduce the sliding resistance of the bottom plate 32 on the base surface 60, improve the smoothness of the movement of the isolation part 30 with the door body 20, and reduce the wear of the bottom plate 32.

[0125] It is understandable that the protective layer 37 can be made of a film material with good wear resistance and sliding properties. For example, the protective layer 37 is made of Teflon tape.

[0126] Combination Figure 2 and Figure 3 As shown, in some embodiments, the isolation part 30 further includes a shaping plate 36 and a protective layer 37. The shaping plate 36 is disposed on a side of the bottom plate 32 away from the base surface 60, and the shaping plate 36 is connected to the connecting plate 31 to maintain the geometric configuration of the connecting plate 31 and the bottom plate 32. The protective layer 37 is disposed on a side of the bottom plate 32 close to the base surface 60 to improve the smoothness of the isolation part 30 moving with the door body 20 and reduce the wear of the bottom plate 32.

[0127] Combination Figures 1 to 8 As shown, the embodiment of the present disclosure further provides a sliding door 40 for a radiation room. The sliding door 40 for a radiation room comprises an isolation door leaf 10 for a radiation room as in any of the previous embodiments.

[0128] The sliding door 40 for a radiation room provided in the embodiment of the present disclosure includes the isolation door leaf 10 for a radiation room, which effectively reduces the radiation leakage and improves the protection effect.

[0129] Exemplarily, the isolation door leaf 10 for a radiation room is used for a single door in the prior art to improve the protection effect.

[0130] Combination Figures 1 to 12 As shown, the embodiment of the present disclosure further provides a sliding door 40 for a radiation room. The sliding door 40 for a radiation room comprises a plurality of isolation door leaves 10 for a radiation room as in any of the previous embodiments.

[0131] The sliding door 40 for a radiation room provided in the embodiment of the present disclosure includes a plurality of the isolation door leaves 10 for a radiation room as described above, which effectively reduces the radiation leakage and improves the protection effect.

[0132] Exemplary, combined Figures 9 to 12 As shown, the isolation door leaf 10 for the radiation room is used for the triple door in the prior art to improve the protection effect.

[0133] Optionally, combined Fig.12 As shown, in the case where the sliding door 40 includes a plurality of isolation door leaves 10, when the sliding door 40 is in a closed state, two adjacent isolation door leaves 10 are partially overlapped.

[0134] In this embodiment, the protective effect is improved by partially overlapping two adjacent isolation door leaves 10 .

[0135] In actual application, shielding and protective materials can be buried in the base surface 60 corresponding to the position of the sliding door 40 to improve the protective effect while ensuring that the base surface 60 is flat as a whole.

[0136] Exemplary, combined Fig.13 and Fig.14 As shown, a sliding door without a protective structure, an existing sliding door with a sunken protective structure, and a sliding door 40 for a radiation room of the present application are installed in a CT room of a hospital as examples to compare and illustrate the protective effect of the present application. Under the premise that the CT machine performs radiation scanning under the same parameter conditions, the radiation dose equivalent rate at the gap 50 between the bottom of the three sliding doors and the base surface 60 is detected respectively. The following results are obtained:

[0137] For the sliding door without a protective structure, the dose equivalent rate of radiation at different points of interest at the gap 50 is 5 μSv / h to 12 μSv / h, far exceeding the value required by the specification (2.5 μSv / h).

[0138] For the existing sliding door with sunken protection structure, the radiation dose equivalent rate at different focus points at the gap 50 is 3μSv / h to 6μSv / h. Although it can reduce the radiation amount to a certain extent, it still exceeds the regulatory requirement value (2.5μSv / h).

[0139] For the sliding door 40 for the radiation room of the present application, the dose equivalent rate of radiation at different points of interest at the gap 50 is 0.6 μSv / h to 1 μSv / h, which fully meets the required value of the specification (2.5 μSv / h).

[0140] In this application, combined Fig.13 and Fig.14 As shown, Fig.13 and Fig.14 The straight arrows in the figure indicate the direction of the radiation. Relative to the height of the radiation source, the gap 50 between the door body 20 and the ground is located at a relatively low position, so mainly scattered or reflected radiation passes through the gap 50, and there is rarely a case where the radiation from the radiation source directly passes through the gap 50.

[0141] In the present application, the rays are isolated and protected by the connecting plate 31 and the bottom plate 32, which can effectively block the rays at the position of the gap 50, so that the rays are reflected or scattered back. In the case where both the bottom plate 32 and the connecting plate 31 are made of shielding and protective materials (such as lead), a part of the ray energy can also be absorbed, that is, after the rays are irradiated on the bottom plate 32 and the connecting plate 31 made of shielding and protective materials, they are attenuated by absorption and scattering, which effectively reduces the amount of radiation leakage. Moreover, in the present application, the bottom plate 32 protrudes from the connecting plate 31, which increases the contact area and fit between the bottom plate 32 and the base surface 60, and absorbs and blocks the rays at the position of the gap 50 to the maximum extent, thereby improving the protection effect.
