Description

Technical Field

[0001] This utility model relates to the technical field of structural design of anti-radiation auxiliary components for angiography machine heads, and particularly to anti-radiation components for angiography machine heads and their anti-radiation covers. Background Technology

[0002] An angiography machine, also known as an angiography X-ray machine, is a medical device used for angiography examinations. Its core component is the X-ray generator, which produces a high-energy X-ray beam. During the operation of the angiography machine, X-ray radiation is a significant factor; therefore, the design and application of radiation shielding components on the machine head are particularly important.

[0003] Angiography machines use X-ray imaging technology to clearly display the structure of the human vascular system. During operation, an X-ray generator produces a high-energy X-ray beam. These rays penetrate the patient's body and are received by the image acquisition system, converted into digital signals or real-time images for doctors to observe and diagnose.

[0004] X-rays are electromagnetic waves with extremely short wavelengths and high energy, possessing strong penetrating power. While the use of X-rays is necessary in angiography, it can also pose certain radiation hazards to medical staff and patients. Long-term or excessive exposure to X-ray radiation may lead to skin damage, hematopoietic dysfunction, decreased fertility, and genetic effects.

[0005] In existing technologies, radiation protection is mainly achieved through lead curtains and lead aprons. However, there is no radiation protection device for the head of angiography machines, which poses a radiation hazard to medical staff working in X-ray environments.

[0006] Therefore, it is evident that installing a radiation protection device at the head of angiography machines, which are widely used in existing technologies, can greatly improve the radiation protection effect. However, existing angiography machines do not have radiation protection components, which affects the radiation protection effect. Utility Model Content

[0007] In view of this, the main purpose of this utility model is to provide a radiation protection component for an angiography machine head and a radiation protection sleeve for the angiography machine head that can extend vertically to the upper side of the angiography machine bed body to improve the radiation protection effect.

[0008] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0009] The radiation shielding component of the angiography machine head includes: a storage box, multiple rotating lead plates and a hinge ring. The rotating lead plates have hinge holes on their upper and lower edges, and the hinge ring passes through the hinge holes of adjacent rotating lead plates.

[0010] In a preferred embodiment, the storage box has an opening at the bottom and a hanging ring is fixedly connected to the upper edge inside the storage box. The hanging ring passes through the hinge hole of the uppermost rotating lead plate.

[0011] In a preferred embodiment, the width of the storage box is greater than the width of the rotating lead plate.

[0012] In a preferred embodiment, the distance from the edge of the rotating lead plate to the location of the hinge hole is greater than the radius of the hinge ring, and the distance from the edge of the rotating lead plate to the location of the hinge hole is less than the diameter of the hinge ring.

[0013] In a preferred embodiment, the rotating lead plate has a rectangular structure, and the hinge hole is located on the long edge of the rectangle.

[0014] In a preferred embodiment, the long rectangular edge of the rotating lead plate is rounded.

[0015] In a preferred embodiment, the cross-section of the hinge ring is circular, and the diameter of the hinge hole is larger than the diameter of the circular cross-section of the hinge ring.

[0016] In a preferred embodiment, the hinge ring has a rectangular cross-section, the hinge hole also has a rectangular cross-section, and the length of the hinge hole is greater than or equal to the length of the hinge ring's cross-section, while the width of the hinge hole is greater than the width of the hinge ring's cross-section.

[0017] In a preferred embodiment, the system further includes: a plurality of vertical lead plates, wherein the upper end of the vertical lead plates is provided with a suspension hole, and the hinge ring connected to the lower side of the lowest rotating lead plate also passes through the suspension hole.

[0018] In a preferred embodiment, the sum of the distance from the hinge hole to the edge and the distance from the suspension hole to the edge is greater than or equal to the diameter of the hinge ring.

[0019] The angiography machine head radiation shield has a square angiography machine head with each side connected to the angiography machine head radiation shield, and the four angiography machine head radiation shields are arranged in a cylindrical shape.

[0020] In a preferred embodiment, the vertical lead plates on both sides of the angiography table are of the same length, and an arc-shaped cavity is formed at the lower end of the vertical lead plate at the upper position of the patient, so that the lower end of the vertical lead plate fits the patient.

[0021] The radiation protection component for the angiography machine head and the radiation protection sleeve for the angiography machine head of this utility model have the following beneficial effects:

[0022] The radiation shielding component of the angiography machine head includes: a storage box, multiple rotating lead plates, and a hinge ring. The rotating lead plates have hinge holes on their upper and lower edges, and the hinge ring passes through the hinge holes of adjacent rotating lead plates. The storage box has an opening at the bottom, and a hanging ring is fixedly connected to the upper edge inside the storage box. The hanging ring passes through the hinge hole of the uppermost rotating lead plate. The width of the storage box is greater than the width of the rotating lead plates.

[0023] The angiography machine head radiation shield has a square angiography machine head with each side connected to the angiography machine head radiation shield, and the four angiography machine head radiation shields are arranged in a cylindrical shape.

[0024] This invention addresses the shortcomings of existing angiography machines, which are widely used in current technology. By installing a radiation protection device at the head of the angiography machine, the radiation protection effect can be greatly improved. However, existing angiography machines do not have radiation protection components, which affects the radiation protection effect.

[0025] The radiation shielding components and cover for the angiography machine head, by connecting a rotating lead plate to the machine head, can extend vertically to the upper side of the angiography machine bed, improving the radiation protection effect. Multiple radiation shielding components form a radiation shielding cover, further completely enveloping the angiography machine head and enhancing its radiation protection function.

[0033] The radiation protection component for the angiography machine head and the radiation protection sleeve for the angiography machine head of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments of this utility model.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0037] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0038] like Figures 1-3 As shown, the radiation shielding component of the angiography machine head includes: a storage box 1 for housing the rotating lead plates 2, multiple rotating lead plates 2 that can be rotatably hinged to each other, and hinge rings 3 for hinged to the rotating lead plates 2. To ensure continuous hinged connection of the rotating lead plates 2 and maintain the length of the radiation shielding component, thereby significantly reducing the radiation exposure to medical personnel from the angiography machine, hinge holes 4 are provided on the upper and lower edges of the rotating lead plates 2. The hinge rings 3 pass through the hinge holes 4 of adjacent rotating lead plates 2. By sliding the hinge rings 3 within the hinge holes 4, the rotation between adjacent rotating lead plates 2 is achieved, thus allowing all rotating lead plates 2 to unfold and isolate radiation. Furthermore, during the rotation of the angiography machine head or the storage of the radiation shielding component, adjacent rotating lead plates 2 rotate relative to each other and, after fitting together, can be stored in the storage box 1.

[0039] Of course, in order to facilitate the storage of the rotating lead plate 2 inside the storage box 1, the storage box 1 is open at the bottom and a hanging ring 5 is fixedly connected to the upper edge inside the storage box 1. The hanging ring 5 passes through the hinge hole 4 of the uppermost rotating lead plate 2. The hanging ring 5 realizes the connection between the rotating lead plate 2 and the storage box 1, ensuring that the rotating lead plate 2 will not fall off the storage box 1.

[0040] The hanging ring 5 is located on the edge to ensure that after the adjacent rotating lead plates 2 are folded relative to each other, they can be completely laid flat inside the storage box 1, reducing the total height of the rotating lead plates 2 after storage and improving the compactness of the entire radiation shield.

[0041] Of course, to ensure that the rotating lead plate 2 can be laid flat and easily stored inside the storage box 1, the width of the storage box 1 is greater than the width of the rotating lead plate 2.

[0042] To ensure a tight fit between adjacent rotating lead plates 2 and reduce the amount of radiation rays passing through the gaps between them, thus affecting the overall radiation shielding effect, the distance from the hinge hole 4 on the rotating lead plate 2 to its edge is greater than the radius of the hinge ring 3, while the distance from the hinge hole 4 on the rotating lead plate 2 to its edge is less than the diameter of the hinge ring 3.

[0043] like Figure 2 As shown, when the upper and lower rotating lead plates 2 rotate along the hinge ring 3, because the distance from the hinge hole 4 to the edge of the rotating lead plate 2 is greater than the radius of the hinge ring 3, interference occurs at one end of the adjacent rotating lead plates 2 inside the hinge ring 3. Under the action of gravity, the lower rotating lead plate 2 rotates downward, pulling the rotation and causing the adjacent rotating lead plates 2 to fit tightly together, thus improving the radiation protection effect.

[0044] To ensure a certain rotation angle and achieve the desired telescopic effect, the distance from the edge of the rotating lead plate 2 to the hinge hole 4 is less than the diameter of the hinge ring 3.

[0045] Preferably, the distance from the edge of the rotating lead plate 2 to the hinge hole 4 is close to the radius of the hinge ring 3.

[0046] Furthermore, during the rotation of the angiography machine head, due to the interference between adjacent rotating lead plates 2, it will not expand to a larger angle or misalignment, ensuring that it will automatically retract into the storage box 1 after rotation, thus facilitating the rotation of the angiography machine head.

[0047] In other words, during the rotation of the angiography machine head, the rotating lead plate 2 is suspended and extended. The opening angle of the adjacent rotating lead plates 2 will not increase, so there will be no defect of the anti-radiation component tilting. Afterwards, the adjacent rotating lead plates 2 rotate and move closer to each other, so they can be conveniently stored during the rotation of the angiography machine head.

[0048] To minimize the width of the storage box and reduce its space occupation after folding, the rotating lead plate 2 has a rectangular structure with hinge holes 4 located on the long edge of the rectangle. During folding and storage, the width of the storage box 1 only needs to be the same as the width of the rectangle to accommodate the rotating lead plate 2.

[0049] To improve the fit between adjacent rotating lead plates 2 and prevent jamming during rotation, which would affect the rotation and unfolding of the lead plates 2, the long edge of the rectangle of the rotating lead plate 2 is rounded. The rounded contact surface ensures that the rotating lead plates 2 can smoothly rotate closer or open.

[0050] In a preferred embodiment, the hinge ring 3 has a circular cross-section. To ensure that the hinge ring 3 slides smoothly along the hinge hole 4, the diameter of the hinge hole 4 is larger than the diameter of the circular cross-section of the hinge ring 3. The circular cross-section structure of the hinge ring 3 improves the smoothness of sliding along the hinge hole 4 and avoids jamming.

[0051] To improve the constraint on the rotating lead plate 2 and prevent the hinge ring 3 with a circular cross-section from being misaligned, the cross-section of the hinge ring 3 is rectangular, and the cross-section of the hinge hole 4 is also rectangular. The length of the cross-section of the hinge hole 4 is greater than or equal to the length of the cross-section of the hinge ring 3, and the width of the cross-section of the hinge hole 4 is greater than the width of the cross-section of the hinge ring 3.

[0052] Preferably, both ends of the hinge hole 4 are open structures with rounded transitions to ensure smooth sliding of the hinge ring 3.

[0053] To further enhance the radiation protection effect, the system also includes multiple vertical lead plates 6 that are close to the patient's body. Each vertical lead plate 6 has a hanging hole 7 at its upper end, and a hinge ring 3 connected to the lower side of the lowest rotating lead plate 2 passes through the hanging hole 7. The hanging hole 7 allows for the connection between the vertical lead plate 6 and the rotating lead plate 2, ensuring that the vertical lead plate 6 extends to a predetermined height, fitting more closely to the patient's body surface and minimizing the impact of radiation on medical personnel.

[0054] Similarly, to improve the fit between the vertical lead plate 6 and the rotating lead plate 2, the sum of the distance from the hinge hole 4 to the edge and the distance from the suspension hole 7 to the edge is greater than or equal to the diameter of the hinge ring 3. Under the influence of gravity, the vertical lead plate 6 pulls the hinge ring 3 downward, and the rotating lead plate 2 rotates upward along the hinge hole 4, so that the upper end of the vertical lead plate 6 and the lower end of the rotating lead plate 2 fit together, improving the radiation protection effect. Since the rotating lead plate 2 is not completely vertical, the sum of the distance from the hinge hole 4 to the edge and the distance from the suspension hole 7 to the edge is set to be relatively large (greater than the diameter of the hinge ring 3), ensuring that when the radiation protection component is completely vertical, the vertical lead plate 6 fits as closely as possible to the rotating lead plate 2, improving the radiation protection effect.

[0055] To adapt to the angiography machine head and provide comprehensive radiation protection for the angiography machine head, a radiation protection sleeve for the angiography machine head has also been disclosed. Each side of the square angiography machine head is connected to the aforementioned radiation protection component (adhesive or snap-fit, as long as it can be securely fixed to the angiography machine head), and the four radiation protection components are arranged in a cylindrical shape.

[0056] The vertical lead plates 6 on both sides of the angiography table are of the same length. An arc-shaped cavity 8 is formed at the lower end of the vertical lead plate 6 above the patient, so that the lower end of the vertical lead plate 6 fits the patient. The patient lies under the arc-shaped cavity 8, which improves the fit between the patient and the cavity.

[0057] Between adjacent radiation shielding components, one side of the rotating lead plate 2 is a rectangular structure, while the other side is an isosceles trapezoidal structure. The inclination angle of the hypotenuse of the isosceles trapezoid is the same as the angle between the rotating lead plate 2 and the horizontal plane when it is completely vertical, making the adjacent radiation shielding components fit more closely. The isosceles trapezoidal structure extends into the bending gap of the rectangular structure, improving the radiation shielding effect.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
