Description

Technical Field

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

[0002] Hospital radiology departments frequently use X-rays to examine patients' internal organs. Since prolonged exposure to X-rays can cause certain harm, protective devices are usually used to shield other parts of the patient's body.

[0003] A search revealed patent application number (202222599443.X), which discloses a "radiation protection device," comprising a device body and an internal protective plate. The device body has an inner cavity and a first opening and a second opening communicating with the inner cavity. The internal protective plate is disposed in the inner cavity along a first direction and is made of radiation-shielding material, along with the device body. The internal protective plate is spaced apart from the inner surface of the device body in a second direction perpendicular to the first direction. The first opening and the second opening are disposed opposite each other on both sides of the internal protective plate along a third direction perpendicular to both the first and second directions. The projections of the first opening and the second opening on a reference plane parallel to the internal protective plate are completely located within the projection of the internal protective plate on the reference plane. According to this application, the radiation protection device can be installed at the ventilation openings of air conditioners and exhaust fans in medical imaging radiation protection equipment, effectively protecting against direct leakage of radiation from all directions, weakening the intensity of these radiations, and thus preventing radiation leakage. However, the above-mentioned device has the following problems: in order to accommodate patients of various body types and patients with different examination sites, a large space is reserved between the shielding component and the patient. Moreover, the shielding component of the existing protective bed has limited flexibility and it is not easy to adjust the distance between the shielding component and the patient according to the specific condition of the patient, which increases the radiation exposure area and increases the radiation impact on the surrounding environment. Therefore, we propose a radiation protection device for medical radiological diagnosis and treatment to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a radiation protection device for medical radiological diagnosis and treatment, in order to solve the problems mentioned in the background art, such as the limited flexibility of the shielding components of existing protective beds, the difficulty in adjusting the distance between the shielding components and the patient according to the specific condition of the patient, the increase in the radiation exposure area, and the increase in the radiation impact of the surrounding environment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a radiation protection device for medical radiological diagnosis and treatment, comprising a treatment bed and a diagnostic frame, wherein the diagnostic frame is placed on the outside of the treatment bed, two sets of protective covers are provided on the surface of the treatment bed, an adjustment mechanism is provided on the outside of the protective covers, and a positioning component is provided at the edge of the treatment bed; The adjustment mechanism includes a distance adjustment component, an angle adjustment component, and a height adjustment component. The distance adjustment component is located inside the treatment bed to adjust the distance between the two sets of protective covers. The angle adjustment component is located outside the treatment bed to control the angle of the protective cover. The height adjustment component is located between the protective cover and the angle adjustment component to control the height of the protective cover.

[0006] Preferably, the protective cover consists of a main rod, a secondary rod, and a first protective curtain. Multiple sets of secondary rods are connected to the outside of the main rod, and the secondary rods are connected to the main rod by the first protective curtain.

[0007] Preferably, the distance adjustment component consists of a first electric push rod and a connecting rod. The first electric push rod is symmetrically installed inside the treatment bed. The output end of the first electric push rod is fixedly connected to the connecting rod. The treatment bed has a first sliding groove adapted to the connecting rod.

[0008] Preferably, the angle adjustment assembly consists of a servo motor and a connector. The servo motor is fixedly installed inside the connecting rod, the output end of the servo motor is fixedly connected to the connector, and a protective cover is connected to the outside of the connector.

[0009] Preferably, the height adjustment assembly consists of a second electric push rod, a first connecting ring, and a second connecting ring. The second electric push rod is fixedly installed inside the connector, and the second connecting ring is connected to the outside of the main rod. The output end of the second electric push rod is fixedly connected to the first connecting ring, and the first connecting ring is connected to the second connecting ring.

[0010] Preferably, the positioning component includes a second movable groove, a third electric push rod, a connecting block, a second magnet, and an adsorption block. The second movable groove is provided on both sides of the inside of the treatment bed. The third electric push rod is fixedly installed inside the second movable groove. The output end of the third electric push rod is fixedly connected to the connecting block. The second magnet is embedded inside the connecting block. The bottom of the first protective curtain is slidably connected to the adsorption block.

[0011] Preferably, the protective cover further includes a fixing rod, an elastic band, a second protective curtain, and a first magnet. Two sets of fixing rods are fixedly connected to the outer surface of the outermost auxiliary rod. An elastic band is fixedly connected to the other end of the fixing rod. A second protective curtain is fixedly connected to the bottom of the elastic band. Two sets of elastic bands are installed on the edge of the elastic band.

[0012] Preferably, the first connecting ring and the second connecting ring are connected by bolts.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention adjusts the position of the protective shields based on signals from whole-body or localized patient detection using an adjustable mechanism. By controlling the position, angle, and height of the two sets of protective shields according to the detection location and the patient's height and weight data, the range of the two sets of shields is adjusted. This ensures that the shielding area is adapted to the patient's actual needs, blocking unnecessary areas, reducing radiation exposure, minimizing the radiation impact from the surrounding environment, and improving the protective effect.

[0014] 2. This invention achieves precise movement of the secondary rod and tight wrapping of the detection head through the setting of the positioning component. This structural design can further reduce the irradiation range. The second protective curtain after wrapping can block radiation scattering around the detection head, effectively shielding non-detection areas (such as the skin tissue on both sides of the detection head), thus reducing the irradiation range compared to the unwrapped state. At the same time, the tight fit between the elastic band and the detection head reduces radiation leakage to the surrounding environment, further reducing the radiation exposure risk to medical personnel and surrounding areas. The overall protection effect is improved compared to traditional protective devices without positioning components, ensuring complete shielding of areas that do not need to be exposed, and significantly enhancing the accuracy of protection.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-6 This invention provides an embodiment of a radiation protection device for medical radiological diagnosis and treatment, comprising a treatment bed 1 and a diagnostic rack 2. The treatment bed 1 has a control panel mounted on its outer surface and an internal PLC controller for controlling internal electronic components. The diagnostic rack 2 is placed on the outer side of the treatment bed 1. Two sets of protective covers 3 are provided on the surface of the treatment bed 1, and an adjustment mechanism 4 is provided on the outer side of the protective covers 3. A positioning component 5 is provided at the edge of the treatment bed 1. The adjustment mechanism 4 includes a distance adjustment component 41, an angle adjustment component 42, and a height adjustment component 43. The distance adjustment component 41 is located inside the treatment bed 1 to adjust the distance between the two sets of protective covers 3. The angle adjustment component 42 is located on the outer side of the treatment bed 1 to control the angle of the protective covers 3. The height adjustment component 43 is located between the protective covers 3 and the angle adjustment component 42 to control the height of the protective covers 3. Patient data is input through the control panel, thereby activating the distance adjustment component 41, the angle adjustment component 42, and the height adjustment component 43 to adjust the position of the protective covers 3. This device, through the setting of adjustment mechanism 4, solves the problem that the shielding components of existing protective beds have limited flexibility, making it difficult to adjust the distance between the shielding components and the patient according to the patient's specific condition, thus increasing the area of ​​radiation exposure and the radiation impact on the surrounding environment.

[0020] Furthermore, the protective cover 3 consists of a main rod 301, secondary rods 302, and a first protective curtain 303. Multiple sets of secondary rods 302 are connected to the outer side of the main rod 301. A first protective curtain 303 connects the secondary rods 302 to the main rod 301, and the first protective curtain 303 has a lead plate inside. For example... Figure 2 As shown, this structure is used to connect multiple sets of auxiliary rods 302 through the first protective curtain 303 and to link with the main rod 301, so that the first protective curtain 303 covers the designated position to protect the patient.

[0021] Furthermore, the distance adjustment assembly 41 consists of a first electric push rod 411 and a connecting rod 412. The first electric push rod 411 is symmetrically installed inside the treatment bed 1, and the output end of the first electric push rod 411 is fixedly connected to the connecting rod 412. A first sliding groove 413 adapted to the connecting rod 412 is provided inside the treatment bed 1. For example... Figure 3 As shown, this structure is used to activate the first electric push rod 411 through the patient detection position, which drives the connecting rod 412 to move along the first slide groove 413 to cover the undetected position and improve the protective effect.

[0022] Furthermore, the angle adjustment assembly 42 consists of a servo motor 421 and a connector 422. The servo motor 421 is fixedly installed inside the connecting rod 412, and the output end of the servo motor 421 is fixedly connected to the connector 422. A protective cover 3 is connected to the outside of the connector 422. Figure 5 As shown, this structure is used to adjust the angle of the protective cover 3 by activating the servo motor 421 according to the patient's body shape, driving the connector 422 to rotate, thereby adapting to patients of different body shapes.

[0023] Furthermore, the height adjustment assembly 43 consists of a second electric push rod 431, a first connecting ring 432, and a second connecting ring 433. The second electric push rod 431 is fixedly installed inside the connector 422, and the second connecting ring 433 is connected to the outside of the main rod 301. The output end of the second electric push rod 431 is fixedly connected to the first connecting ring 432, and the first connecting ring 432 is connected to the second connecting ring 433. Figure 5 As shown, this structure is used to activate the second electric push rod 431 based on the patient's body shape data, thereby driving the protective cover 3 to rise and fall to match the patient's body shape.

[0024] Furthermore, the positioning component 5 includes a second movable groove 501, a third electric push rod 502, a connecting block 503, a second magnet 504, and an adsorption block 505. The second movable groove 501 is provided on both sides of the inside of the treatment bed 1. The edges of the second movable groove 501 are rounded, and the inner wall is marked with color to prevent the patient from covering the second movable groove 501 when lying on the treatment bed 1. The third electric push rod 502 is fixedly installed inside the second movable groove 501. The output end of the third electric push rod 502 is fixedly connected to the connecting block 503. The second magnet 504 is embedded inside the connecting block 503. The bottom of the first protective curtain 303 is slidably connected to the adsorption block 505. The top of the adsorption block 505 is T-shaped, and the bottom is spherical. The adsorption block 505 falls into the second movable groove 501 under the action of gravity. Figure 6 As shown, this structure is used to connect the adsorption block 505 and the connecting block 503 through the adsorption effect of the second magnet 504, and to activate the third electric push rod 502. The adsorption block 505 pulls the auxiliary rod 302 to extend, expand the shielding range, and improve the protection effect.

[0025] Furthermore, the protective cover 3 also includes a fixing rod 304, an elastic band 305, a second protective curtain 306, and a first magnet 307. Two sets of fixing rods 304 are fixedly connected to the outer surface of the outermost auxiliary rod 302. The length of the fixing rod 304 is consistent with the radius of the detection head of the diagnostic frame 2. An elastic band 305 is fixedly connected to the other end of the fixing rod 304. The second protective curtain 306 is fixedly connected to the bottom of the elastic band 305, and two sets of elastic bands 305 are installed along the edge of the elastic band 305. For example... Figure 2 As shown, this structure is used to gradually shorten the distance between the two sets of protective covers 3, so that the first magnets 307 at the elastic band 305 attract each other. At this time, under the elastic action of the elastic band 305, the second protective curtain 306 surrounds the detection head at the diagnostic frame 2, thereby avoiding scattering leakage.

[0026] Furthermore, the first connecting ring 432 and the second connecting ring 433 are connected by bolts 434. For example... Figure 5 As shown, this structure is used to unlock the protective cover 3 by rotating the bolt 434, and can adjust the angle of the protective cover 3 or remove the protective cover 3 for replacement.

[0027] Working principle: When using, such as Figure 1 As shown, the patient lies on treatment bed 1. The patient's detection location and height / weight data are entered into the control panel. Figure 3 and Figure 5As shown, the servo motor 421 is activated, driving the connector 422 to rotate, thus adjusting the angle of the protective cover 3. Then, the second electric push rod 431 is activated, causing the protective cover 3 to rise and fall to accommodate patients of different body types. Next, the first electric push rod 411 is activated, driving the connecting rod 412 to move along the first slide groove 413, covering undetected areas. Figure 2 and Figure 6 As shown, the adsorption block 505 is connected to the connecting block 503 by the adsorption effect of the second magnet 504. The third electric push rod 502 is activated, and the auxiliary rod 302 is extended by the adsorption block 505, so that the first protective curtain 303 covers the designated position to protect the patient. The above is the entire working principle of the present invention.
