Description

Technical Field

[0001] This invention relates to the field of medical radiation protection devices, specifically to a radiation protection device and method for medical diagnosis. Background Technology

[0002] Radiation protection devices for medical diagnosis are radiation protection devices specifically designed for medical diagnostic scenarios. They are usually made of lead rubber, lead composite materials, etc., and can effectively shield ionizing radiation such as X-rays.

[0003] Radiation protection devices for medical diagnostics are mainly classified into the following categories: 1. Mobile protective screens, made of lead composite plates, lead glass, etc., equipped with wheeled support frames, allowing for flexible movement. Commonly used in operating rooms, emergency rooms, and other settings, they effectively block X-ray scattering, protecting medical staff and patients. 2. Suspended protective screens, using spring arms, extension arms, and other suspension structures, can rotate around a fixed base. Suitable for interventional procedures and other operations, they allow for flexible adjustment of angle and position, reducing the scattered radiation received by the operator. 3. Bedside protective curtains, fixed to the side of the bed and supported by multiple rotatable support rods. These are divided into under-bed curtains and in-bed protective barriers, protecting those around the patient from scattered radiation.

[0004] Existing radiation shielding screens for medical diagnostics typically use hinges to connect multiple panels. This structure allows the panels to rotate at a specific angle, thus achieving folding. However, after folding or unfolding, this design often suffers from insufficient stability due to the hinge structure itself, leading to risks such as wobbling and loosening. Therefore, there is an urgent need to provide a new type of radiation protection device to address this structural deficiency. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a radiation protection device for medical diagnosis, so as to solve the problem that the existing radiation protection screens for medical diagnosis often have insufficient overall stability due to the hinge structure itself.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A radiation protection device for medical diagnostics, comprising:

[0008] The main protective screen has side protective screens connected to both ends of the main protective screen via flip units. The side protective screens are internally telescopically connected to a first auxiliary protective screen and a second auxiliary protective screen.

[0009] A drive unit is installed inside the side protective screen and connected to the first auxiliary protective screen, used to drive the first auxiliary protective screen to slide along the inner wall of the side protective screen;

[0010] The lifting unit is rotatably connected inside the first auxiliary protective screen and connected to the second auxiliary protective screen. It is used to cooperate with the drive unit to realize the two-stage extension and retraction of the second auxiliary protective screen inside the side protective screen.

[0011] As a preferred embodiment of the present invention, the flipping unit includes: an extension seat fixed to the inner wall of the main protective screen, with a first sliding post and a second sliding post fixed on its surface; a bracket connected to the side of the side protective screen, with a first sliding groove and a second sliding groove opened on its surface, the first sliding post and the second sliding post being slidably connected inside the first sliding groove and the second sliding groove respectively; and an arc-shaped groove opened on the bracket, with one end communicating with the second sliding groove, and one end of the first sliding groove located at the center of the arc-shaped groove.

[0012] As a preferred embodiment of the present invention, the bottom of the main protective screen and the two sets of side protective screens are all fixed with support frames, and the bottom of the support frames are equipped with casters.

[0013] As a preferred embodiment of the present invention, the driving unit includes: a slide rail, which is provided on the side of the side protective screen; a sliding frame, which is slidably connected to the surface of the slide rail, and two sets of racks are respectively provided on the two sides; a cylinder, which is installed inside the side protective screen, and the output end of the cylinder is connected to the sliding frame; a rotating shaft, which is rotatably connected to the inside of the side protective screen, and gears are installed on its surface, with two sets of gears meshing with two sets of racks respectively; and a double connecting rod, one end of which is fixed on the rotating shaft, and the other end of which is hinged to the bottom of the first auxiliary protective screen.

[0014] As a preferred embodiment of the present invention, the lifting unit includes: a guide rod, fixed to the side of the first auxiliary protective screen, with a sliding member slidably connected to its surface; a pulley, rotatably connected to the first auxiliary protective screen, with the two sets of pulleys driven by a belt; a fixing frame, connected to the inner wall of the side protective screen on one side, and fixed to the pulley on the other end; and a connecting frame, fixed to the inner wall of the second auxiliary protective screen on one side, and fixed to the surface of the belt on the other end.

[0015] As a preferred embodiment of the present invention, a locking unit is slidably connected inside the main protective screen. When the main protective screen and the two sets of side protective screens are opened, the locking unit slides downward inside the main protective screen to lock the position of the main protective screen.

[0016] As a preferred embodiment of the present invention, the locking unit includes: a slider, which is laterally slidably connected inside the main protective screen, and a first magnet is fixed at the end of the slider; a second magnet, which is installed at the ends of the two sets of side protective screens; a slanted groove, which is formed on the surface of the slider; a slide rod, which is vertically slidably connected inside the main protective screen, and a sliding shaft is fixed on the side of the slide rod, and the end of the sliding shaft is slidably connected inside the slanted groove; and a locking frame, which is fixed to the lower end of the slide rod.

[0017] As a preferred embodiment of the present invention, a protective unit is installed inside the side protective screen. The protective unit is connected to the side of the second auxiliary protective screen and can be driven by the second auxiliary protective screen to rise and fall inside the side protective screen to block radiation together with the side protective screen. The protective unit includes: a take-up roller, both ends of which are rotatably installed inside the side protective screen and connected to the inner wall of the side protective screen by a torsion spring; and a protective curtain, one end of which is wrapped around the surface of the take-up roller and the other end of which is fixed to the upper side of the second auxiliary protective screen.

[0018] A radiation protection method for medical diagnostics includes the following steps:

[0019] Step 1: Use the casters to move the main protective screen and side protective screens to the designated position as a whole;

[0020] Step 2: Manually rotate the side protective screen so that it rotates 90 degrees around the first sliding pin until the side protective screen opens, and then push the side protective screen to lock it.

[0021] Step 3: Activate the cylinder and adjust the first and second auxiliary protective screens to the appropriate positions;

[0022] Step 4: Rotate the side protective screen 90 degrees in the opposite direction so that the main protective screen and the side protective screen are perpendicular, thus folding the main protective screen and the side protective screen.

[0023] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: The radiation protection device for medical diagnosis of the present invention has two usage states. By opening the two sets of side protective screens to quickly form a protective area, the protection range of the protective device can be expanded, providing more comprehensive radiation shielding for operators and patients, reducing the irradiation of scattered rays on the body, and reducing radiation risk.

[0024] By folding the two sets of side shields, the protective device can be folded into a semi-cylindrical shape. Medical staff can stand inside the semi-cylindrical protective device, and the main shield and side shields can be moved as a whole using casters, which can effectively block the scattered radiation of X-rays. Alternatively, the barrel-shaped protective device can be surrounded around the patient or examination site to form a closed or semi-closed space, which can effectively block scattered rays, reduce the radiation exposure of surrounding personnel and the environment, and protect the safety of medical staff and patients.

[0025] In contrast to the traditional method of directly hinged side protective screens to the main protective screen, the embodiments of the present invention, by designing a first sliding groove and a second sliding groove, and cooperating with the first sliding post and the second sliding post, can ensure the stability of the two sets of side protective screens after they are opened or folded. This design not only effectively avoids the risk of shaking or loosening that exists in traditional hinge structure connections, but also enables the side protective screens to withstand lateral loads after they are fully unfolded or folded, thereby enhancing the rigidity and reliability of the overall structure.

[0026] The present invention is provided with a first auxiliary protective screen and a second auxiliary protective screen. By raising and lowering the first auxiliary protective screen and the second auxiliary protective screen to a predetermined position within the side protective screen, the first auxiliary protective screen and the second auxiliary protective screen together with the main protective screen constitute a continuous and complete anti-radiation system, which ensures the rapid and stable expansion of the protective area of ​​the protective device in a limited space, and effectively improves the overall protective capability of the device.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0042] See Figures 1 to 11 A radiation protection device for medical diagnostics, comprising:

[0043] Main protective screen 1, with side protective screens 2 connected to both ends of the main protective screen 1 via flipping units 3, and a first auxiliary protective screen 41 and a second auxiliary protective screen 42 internally telescopically connected to the side protective screen 2;

[0044] The drive unit 5 is installed inside the side protective screen 2 and connected to the first auxiliary protective screen 41, and is used to drive the first auxiliary protective screen 41 to slide along the inner wall of the side protective screen 2.

[0045] The lifting unit 6 is rotatably connected inside the first auxiliary protective screen 41 and connected to the second auxiliary protective screen 42. It is used to cooperate with the drive unit 5 to realize the two-stage extension and retraction of the second auxiliary protective screen 42 inside the side protective screen 2.

[0046] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the bottom of the main protective screen 1 and the two sets of side protective screens 2 are all fixed with support frames 11, and the bottom of the support frames 11 is equipped with casters 12.

[0047] In this embodiment, the main protective screen 1 and the side protective screen 2 are moved as a whole by the casters 12. The operator can easily move the folded protective device to the target location, and then quickly unfold and lock the side protective screen 2 according to the needs of the site to form a complete and continuous isolation barrier. The support frame 11 is designed perpendicular to the main protective screen 1, which reduces the safety risks of the protective device tipping over or being damaged, and ensures safety during use.

[0048] In one embodiment of the present invention, such as Figure 6 and Figure 10 As shown, the flipping unit 3 includes:

[0049] The extension seat 31 is fixed to the inner wall of the main protective screen 1, and the surface is fixed with the first sliding post 36 and the second sliding post 37.

[0050] The bracket 32 ​​is connected to the side of the side protective screen 2, and the surface is provided with a first sliding groove 33 and a second sliding groove 34. The first sliding column 36 and the second sliding column 37 are respectively slidably connected inside the first sliding groove 33 and the second sliding groove 34.

[0051] An arc-shaped groove 35 is formed on the bracket 32, and its end is connected to the second sliding groove 34. One end of the first sliding groove 33 is located at the center of the arc-shaped groove 35.

[0052] In this embodiment, the radiation protection device for medical diagnosis of the present invention has two usage states, such as... Figure 1 As shown, when medical staff need to perform surgery or examinations, the protective device can be folded into a semi-cylindrical shape. Medical staff can stand inside the semi-cylindrical protective device, and the main protective screen 1 and side protective screen 2 can be moved as a whole using the casters 12. This effectively blocks scattered X-ray radiation, reducing radiation exposure for operators and those around patients. The lead equivalent of the main protective screen 1 and side protective screen 2 is typically 0.5 mmPb or higher, effectively attenuating X-rays. This protective device is suitable for various medical scenarios, such as interventional surgery and bedside X-ray examinations, providing effective radiation protection for operators and patients.

[0053] When it is necessary to open the left-side protective screen 2, refer to Figure 7First, manually rotate the side protective screen 2 counterclockwise, causing it to rotate 90 degrees counterclockwise around the first sliding post 36. During this rotation, the side protective screen 2 will drive the arc-shaped groove 35 to rotate synchronously via the bracket 32, causing the arc-shaped groove 35 to slide on the surface of the second sliding post 37 until the second sliding post 37 slides to the end of the arc-shaped groove 35 near the end of the second sliding groove 34. At this point, both the first and second sliding grooves 33 and 34 are rotated to a horizontal position. Push the side protective screen 2 to the right, causing the first sliding post 36 and the second sliding post 37 to slide to the left inside the first and second sliding grooves 33 and 34 respectively, until both slide to the leftmost end of the first and second sliding grooves 33 and 34 (e.g., ...). Figure 11 (in this state), the left side protective screen 2 opens to the same direction as the main protective screen 1, and similarly, the right side protective screen 2 can be opened. For example... Figure 8 and Figure 10 As shown, by opening the two sets of side protective screens, a protective area can be quickly formed, facilitating medical staff to observe the operation process and improving work efficiency. At the same time, it can effectively expand the protective range of the protective device, providing more comprehensive radiation shielding for operators and patients, reducing the exposure of scattered rays to the body, and lowering the risk of radiation exposure.

[0054] When it is necessary to fold the left side protective screen 2, refer to Figure 11 In the opposite direction to the above process, first pull the side protective screen 2 to the left, so that the first sliding column 36 and the second sliding column 37 slide to the rightmost position of the first sliding groove 33 and the second sliding groove 34. Then rotate the side protective screen 2 clockwise, so that the second sliding column 37 slides in the arc groove 35 until the second sliding column 37 slides to the end of the arc groove 35 away from the second sliding groove 34. At this time, the main protective screen 1 and the side protective screen 2 are in a vertical state. Similarly, the other set of side protective screens 2 can be folded.

[0055] Preferably, the surface of the main protective screen 1 can also be equipped with a handle to further improve the flexibility of the protective device's movement. For example... Figure 1 and Figure 6 As shown, by folding the two sets of side protective screens 2 and the main protective screen 1 into a semi-cylindrical shape, medical staff can quickly move the protective device to different examination areas to meet the needs of bedside examinations, emergency rescues, and other scenarios. Furthermore, the cylindrical protective device can form a closed or semi-closed space around the patient or examination site, effectively blocking scattered rays, reducing radiation exposure to surrounding personnel and the environment, and protecting the safety of medical staff and patients.

[0056] Compared to the traditional side protective screen 2 which is directly hinged to the main protective screen 1, the design of the first sliding groove 33 and the second sliding groove 34, which cooperate with the first sliding post 36 and the second sliding post 37, can ensure the stability of the two sets of side protective screens 2 after they are opened or folded. This design not only effectively avoids the risk of shaking or loosening that exists in the traditional hinge structure connection, but also enables the side protective screen 2 to withstand the load from the side after it is fully unfolded or folded, thus enhancing the rigidity and reliability of the overall structure.

[0057] In one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the driving unit 5 includes:

[0058] Slide rail 51 is located on the side of side protective screen 2;

[0059] The sliding frame 52 is slidably connected to the surface of the slide rail 51, and two sets of racks 521 are respectively provided on both sides;

[0060] Cylinder 53 is installed inside the side protective screen 2, and the output end of cylinder 53 is connected to the sliding frame 52;

[0061] A rotating shaft 54 ​​is rotatably connected inside the side protective screen 2, and gears 55 are mounted on its surface. Two sets of gears 55 are respectively meshed with two sets of racks 521.

[0062] The double connecting rod 56 has one end fixed to the rotating shaft 54 ​​and the other end hinged to the bottom of the first auxiliary protective screen 41.

[0063] In this embodiment, when the height of the main protective screen 1 or the side protective screen 2 needs to be adjusted, the cylinder 53 is activated. The output end of the cylinder 53 will drive the sliding frame 52 to slide on the slide rail 51. When the sliding frame 52 slides to the left, it will drive the two sets of racks 521 on its side to slide synchronously. The two sets of racks 521 will drive the two sets of rotating shafts 54 to rotate inside the side protective screen 2 through the gear 55. Specifically, the left rotating shaft 54 ​​rotates counterclockwise and the right rotating shaft 54 ​​rotates clockwise. The two sets of double connecting rods 56 will gradually open, so that the two sets of double connecting rods 56 push the first auxiliary protective screen 41 to slide upward inside the side protective screen 2.

[0064] By adjusting the vertical area of ​​the main protective screen 1, more or more critical areas can be covered according to actual needs, effectively blocking scattered X-ray radiation and reducing radiation exposure for operators and patients outside the examination area. Medical staff can perform examinations more conveniently while maintaining a safe distance, reducing radiation risks and improving work efficiency.

[0065] In one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the lifting unit 6 includes:

[0066] The guide rod 61 is fixed to the side of the first auxiliary protective screen 41, and a sliding member 62 is slidably connected to its surface;

[0067] The pulley 63 is rotatably connected to the first auxiliary protective screen 41. The two sets of pulleys 63 are driven by the belt 64. The pulley 63 and the belt 64 can also be a chain and a sprocket, which can be selected by those skilled in the art according to their needs.

[0068] The mounting bracket 65 is connected to the inner wall of the side protective screen 2 on one side and fixed to the pulley 63 on the other end.

[0069] The connecting bracket 66 is fixed to the inner wall of the second auxiliary protective screen 42 on one side and fixed to the surface of the belt 64 on the other end.

[0070] In this embodiment, when the first auxiliary protective screen 41 rises inside the side protective screen 2, it will drive the belt 64 to rise synchronously through two sets of pulleys 63. Since a point on the belt 64 is fixed to the inner wall of the side protective screen 2 by the fixing frame 65, the belt 64 will rotate counterclockwise on the two sets of pulleys 63 during the rising process. When the belt 64 is in motion, it will rise along the connecting frame 66 on its right side. The connecting frame 66 will drive the second auxiliary protective screen 42 to slide upward on the inner wall of the first auxiliary protective screen 41. The guide rod 61 and the sliding member 62 can guide and limit the second auxiliary protective screen 42, thereby improving the stability of the second auxiliary protective screen 42 during the rising process.

[0071] In summary, after cylinder 53 is activated, the first auxiliary protective screen 41 slides upward inside the side protective screen 2. Simultaneously, under the action of the lifting unit 6, the second auxiliary protective screen 42 also slides upward on the surface of the first auxiliary protective screen 41, thereby rapidly increasing the vertical protective area of ​​the main protective screen 1. When the first and second auxiliary protective screens 41 and 42 reach their predetermined positions, they together with the main protective screen 1 form a continuous and complete radiation protection system, ensuring the rapid and stable expansion of the protective area of ​​the protective device within a limited space, effectively improving the overall protective capability of the equipment.

[0072] The main protective screen 1 is also equipped with a first auxiliary protective screen 41 and a second auxiliary protective screen 42 inside. The structure and working principle are the same as those of the first auxiliary protective screen 41 and the second auxiliary protective screen 42 inside the side protective screen 2, and will not be described in detail here.

[0073] In one embodiment of the present invention, such as Figure 8 and Figure 9As shown, a locking unit 7 is slidably connected inside the main protective screen 1. When the main protective screen 1 and the two sets of side protective screens 2 are opened, the locking unit 7 slides downward inside the main protective screen 1 to lock the position of the main protective screen 1. The locking unit 7 includes:

[0074] The slider 71 is horizontally connected to the inside of the main protective screen 1, and the first magnet 72 is fixed at the end of the slider 71.

[0075] The second magnet 721 is installed at the ends of the two sets of side protective screens 2;

[0076] The inclined groove 73 is formed on the surface of the slider 71;

[0077] The slide bar 74 is vertically slidably connected inside the main protective screen 1. A sliding shaft 75 is fixed on the side of the slide bar 74, and the end of the sliding shaft 75 is slidably connected inside the inclined groove 73.

[0078] The locking bracket 76 is fixed to the lower end of the slide bar 74.

[0079] In this embodiment, as Figure 8 As shown, when the two sets of side protective screens 2 are opened, the ends of the side protective screens 2 are located at the ends of the main protective screen 1. Thus, the first magnet 72 is located on the side of the second magnet 721. Under the attraction of the magnetic force, the second magnet 721 will pull the slider 71 to slide to the right. Thus, the slider 71 will drive the inclined groove 73 to slide. Thus, the sliding rod 74 will slide downward inside the main protective screen 1 under the action of the inclined groove 73 and the sliding shaft 75. The sliding rod 74 will drive the locking frame 76 at the bottom to slide downward synchronously until the locking frame 76 touches the ground. Thus, after the side protective screens 2 are opened, the main protective screen 1 can be automatically fixed.

[0080] By automatically fixing the main protective screen 1 after the side protective screen 2 opens, the protective device can be quickly positioned and fixed in a suitable location, improving work efficiency. This is especially convenient in emergency or high-frequency use scenarios, preventing the device from accidentally sliding or tipping over during use, thereby ensuring the reliability of the protective effect and reducing the risk of radiation leakage.

[0081] In one embodiment of the present invention, such as Figure 3 As shown, a protective unit 8 is installed inside the side protective screen 2. The protective unit 8 is connected to the side of the second auxiliary protective screen 42 and can be driven by the second auxiliary protective screen 42 to rise and fall inside the side protective screen 2, so as to block radiation together with the side protective screen 2. The protective unit 8 includes:

[0082] The take-up roller 81 is rotatably mounted inside the side protective screen 2 at both ends and is connected to the inner wall of the side protective screen 2 by a torsion spring;

[0083] The protective curtain 82 has one end wrapped around the surface of the take-up roller 81 and the other end fixed to the upper side of the second auxiliary protective screen 42.

[0084] In this embodiment, protective curtains 82 are installed inside the main protective screen 1 and the side protective screen 2. The protective curtains 82 are made of lead or other high-density materials and can effectively absorb and block ionizing radiation such as X-rays, reducing the radiation dose received by medical staff and patients during radiological diagnosis and treatment.

[0085] When the second auxiliary protective screen 42 rises, it pulls the upper part of the protective curtain 82 upwards. This causes the other end of the curtain 82 to rotate the winding roller 81 inside the side protective screen 2. The rotation of the winding roller 81 compresses the torsion spring, causing the curtain 82 to unroll. When the second auxiliary protective screen 42 slides downwards, the winding roller 81 automatically winds up the curtain 82 under the action of the torsion spring. Therefore, when the first auxiliary protective screen 41 and the second auxiliary protective screen 42 rise and fall, the protective curtain 82 rises and falls synchronously, reducing the tedious manual adjustment required by medical personnel while ensuring effective protection.

[0086] A radiation protection method for medical diagnosis, based on the aforementioned radiation protection device for medical diagnosis, includes the following steps:

[0087] Step 1: Move the main protective screen 1 and the side protective screen 2 together to the designated position using the casters 12;

[0088] Step 2: Manually rotate the side protective screen 2 so that the side protective screen 2 rotates 90 degrees around the first sliding column 36 until the side protective screen 2 opens, and push the side protective screen 2 to lock it.

[0089] Step 3: Activate cylinder 53 and adjust the first auxiliary protective screen 41 and the second auxiliary protective screen 42 to the appropriate positions;

[0090] Step 4: Rotate the side protective screen 2 90 degrees in the opposite direction so that the main protective screen 1 and the side protective screen 2 are perpendicular, thereby folding the main protective screen 1 and the side protective screen 2.

[0091] The working principle of this invention is as follows: The radiation protection device for medical diagnosis of this invention has two usage states. When it is necessary to open the opposite protective screen 2, such as... Figure 8 As shown, manually rotate the side protective screen 2 so that the side protective screen 2 rotates 90 degrees around the first sliding column 36 until the side protective screen 2 opens. Then push the side protective screen 2 to lock it. By opening the two sets of side protective screens 2 to quickly form a protective area, the protective range of the protective device can be expanded, providing more comprehensive radiation shielding for operators and patients, reducing the exposure of scattered rays to the body, and reducing radiation risk.

[0092] When the opposite protective screen needs to be folded, such as Figure 1 As shown, first pull the side shield 2 to the left, then rotate it so that the main shield 1 and the side shield 2 are in a vertical position. At this time, the protective device can be folded into a semi-cylindrical shape, and medical staff can stand inside the semi-cylindrical protective device. The main shield 1 and the side shield 2 can be moved as a whole using the casters 12, which can effectively block the scattered radiation of X-rays and reduce the radiation exposure of the operator and people around the patient.

[0093] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
