Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to the body components of digital X-ray imaging equipment and the digital X-ray imaging equipment itself. Background Technology

[0002] Digital radiography (DR) is an advanced medical imaging technology that not only improves image clarity and diagnostic accuracy but also significantly reduces X-ray radiation dose, shortens examination time, and allows for image transmission and storage via network, greatly facilitating clinical applications.

[0003] To meet imaging requirements, the focal distance (focal-to-skin distance) between the camera's focus and the patient's skin must not be too small during DR (Digital Radiography) operation. Therefore, related technologies typically employ a fixed focal-to-skin distance reference element placed at a certain distance from the camera. During the patient's positioning before imaging, bringing them closer to the camera, the focal-to-skin distance reference element prevents the distance between the patient's skin and the camera from becoming too close. While this method ensures the focal-to-skin distance is not too small during use, the use of the focal-to-skin distance reference element results in an excessively large DR device, making it inconvenient to carry and store. Utility Model Content

[0004] Therefore, it is necessary to provide a body component and a digital X-ray imaging device that can not only ensure that the focal length is not too small during use, but also meet the requirements of easy portability and storage of digital X-ray imaging devices.

[0005] A body component of a digital X-ray imaging device, the body component of the digital X-ray imaging device comprising:

[0006] Organism;

[0007] A reference element for the focal length distance is slidably connected to the body, allowing it to extend or retract relative to the body; and

[0008] A locking mechanism capable of locking or unlocking the focal distance reference element.

[0009] In some embodiments, the body includes a base and a guide member. The base has a sliding channel, and the guide member has a guide through hole communicating with the sliding channel. The focal length reference member passes through the guide through hole and is slidably engaged with the sliding channel.

[0010] In some embodiments, the focal distance reference member includes a handle and a pull rod connected together, the handle being located on the side of the guide member opposite to the base, and the pull rod passing through the guide through hole and slidably engaging with the sliding channel.

[0011] In some embodiments, when the focal distance reference member is extended, the distance between the end face of the handle away from the pull rod and the focal point of the body is not less than the minimum focal distance.

[0012] In some embodiments, the pull rod and the guide cooperate to limit the focal distance reference from disengaging from the body.

[0013] In some embodiments, the pull rod includes a rod body and a stop block protruding from the outer peripheral surface of the rod body. The rod body passes through the guide hole, and the stop block is located on the side of the guide member away from the handle. When the reference member is extended, the stop block and the guide member abut against each other.

[0014] In some embodiments, the locking mechanism includes a first magnetic part and a second magnetic part with opposite magnetic properties, the first magnetic part being disposed on the body and the second magnetic part being disposed on the focal distance reference member;

[0015] And / or, the locking mechanism includes a third magnetic part and a metal part, wherein one of the third magnetic part and the metal part is disposed on the body and the other is disposed on the focal distance reference member.

[0016] In some embodiments, the guide member has a first magnetic portion on its end face facing the focal distance reference member, and the focal distance reference member has a second magnetic portion on its end face facing the guide member.

[0018] A digital X-ray imaging device, the digital X-ray imaging device comprising the aforementioned body components of the digital X-ray imaging device.

[0019] The aforementioned digital X-ray imaging equipment includes a body component and a focal-to-skin distance reference piece that are slidably connected to the body, allowing them to extend or retract relative to the body. When the focal-to-skin distance reference piece extends, it acts as a barrier during patient positioning, preventing the distance between the patient's skin and the body from becoming too close, thus preventing the focal-to-skin distance from becoming too small. When the focal-to-skin distance reference piece retracts, the overall size of the body component is smaller, and the locking mechanism can lock the focal-to-skin distance reference piece to the body, preventing it from extending again. This ensures that the body component remains stably small, making it easy to carry and store. Attached Figure Description

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] See Figures 1 to 2 One embodiment of this application provides a digital X-ray imaging device whose body assembly includes a body 100, a focal length reference 200, and a locking mechanism. The focal length reference 200 is slidably connected to the body 100 to extend or retract relative to the body 100. The locking mechanism is capable of locking or unlocking the focal length reference 200.

[0035] In the above embodiment, the focal-to-skin distance reference element 200 is slidably connected to the body 100, thereby allowing it to extend or retract relative to the body 100. When the focal-to-skin distance reference element 200 extends, it acts as a barrier during patient position adjustment, preventing the distance between the patient's skin and the body 100 from becoming too close, thus preventing the focal-to-skin distance from becoming too small. When the focal-to-skin distance reference element 200 retracts, the overall size of the body assembly is smaller, and the locking mechanism can also lock the focal-to-skin distance reference element 200 to the body 100, preventing it from extending again, thereby keeping the body assembly stably in a small size, making it easy to carry and store.

[0036] See Figures 2 to 4 In some embodiments, the body 100 includes a base 110 and a guide member 120. The base 110 has a sliding channel, and the guide member 120 has a guide through hole 121 communicating with the sliding channel. The focal length distance reference member 200 passes through the guide through hole 121 and is slidably engaged with the sliding channel.

[0037] Specifically, the base 110 and the guide member 120 can be fixedly installed by means of bonding, snap-fitting, threaded fastener connection, etc., or they can be integrally formed. The guide through hole 121 passes through the guide member 120, and one end of the guide through hole 121 is connected to the sliding channel. The coke distance reference member 200 can slide back and forth in the sliding channel to achieve extension and retraction. Since the coke distance reference member 200 passes through the guide through hole 121, the guide through hole 121 can limit and guide the coke distance reference member 200, making its sliding process more stable.

[0038] See Figures 2 to 5 In some embodiments, the focal distance reference member 200 includes a handle 210 and a pull rod 220 connected together. The handle 210 is located on the side of the guide member 120 away from the base 110, and the pull rod 220 passes through the guide through hole 121 and is slidably engaged with the sliding channel.

[0039] Specifically, the handle 210 and the pull rod 220 can be fixedly installed by means of bonding, snap-fitting, threaded fastener connection, etc., or they can be integrally molded. The handle 210 can be plate-shaped to facilitate gripping by the operator, who pulls out or pushes back the reference piece 200 by gripping the handle 210. The cross-section of the pull rod 220 can be circular or polygonal. The shape and size of the sliding channel can be matched with the pull rod 220 to improve the smoothness of the pull rod 220 sliding within it.

[0040] See Figures 2 to 5 In some embodiments, when the focal distance reference member 200 is extended, the distance between the end face of the handle 210 away from the pull rod 220 and the focal point of the body 100 is not less than the minimum focal distance.

[0041] Understandably, as the focal-to-skin distance reference element 200 is extended by being pulled, the distance between it and the focal point of the body 100 gradually increases; as the focal-to-skin distance reference element 200 is retracted by being pushed, the distance between it and the focal point of the body 100 gradually decreases. When the focal-to-skin distance reference element 200 is fully extended, the distance between it and the focal point of the body 100 reaches its maximum value. During patient position adjustment, the end face of the handle 210 facing away from the pull rod 220 can act as a reference and a barrier, preventing the distance between the patient's skin and the body 100 from becoming too close, thereby preventing the focal-to-skin distance from becoming too small. Therefore, by limiting the distance between the end face of the handle 210 facing away from the pull rod 220 and the focal point of the body 100 to be no less than the minimum focal-to-skin distance when the focal-to-skin distance reference element 200 is fully extended, it can be ensured that when the patient's position is adjusted to the minimum distance between their skin and the body 100, the focal-to-skin distance still meets the requirement of not being less than the minimum focal-to-skin distance, thus satisfying the imaging requirements.

[0042] See Figures 2 to 5 In some embodiments, the pull rod 220 and the guide 120 cooperate to limit the focal distance reference 200 from detaching from the body 100. In this way, the focal distance reference 200 can be prevented from detaching from the body 100, so that the focal distance reference 200 can stably perform its reference function.

[0043] See Figures 3 to 5 In some embodiments, the pull rod 220 includes a rod body 221 and a stop 222 protruding from the outer peripheral surface of the rod body 221. The rod body 221 passes through the guide hole 121, and the stop 222 is located on the side of the guide member 120 away from the handle 210. When the reference member 200 is extended, the stop 222 and the guide member 120 abut against each other.

[0044] Specifically, the rod 221 and the stop 222 can be integrally formed, or fixedly installed by means of bonding, snap-fitting, threaded fastener connection, etc. The stop 222 can be set at the end of the rod 221 away from the handle 210. In the embodiment shown in the figure, the rod 221 is cylindrical, and the stop 222 is hollow cylindrical, which is sleeved on the outside of the end of the rod 221 away from the handle 210. The cross-section of the guide hole 121 is circular, and its diameter is not less than the diameter of the rod 221 and less than the diameter of the stop 222, so that the rod 221 can pass through the guide hole 121. When the charcoal scrap distance reference member 200 extends outward to a certain distance, the stop 222 will abut against the end face of the guide member 120 away from the handle 210, thereby restricting the charcoal scrap distance reference member 200 from leaving the machine body 100.

[0045] In other embodiments, the cross-sectional dimension of the pull rod 220 gradually increases in the direction gradually moving away from the handle 210, and the maximum cross-sectional dimension of the pull rod 220 is not less than the cross-sectional dimension of the guide hole 121. Thus, when the coke distance reference member 200 extends outward to a certain distance, the pull rod 220 will be stuck by the wall of the guide hole 121 and cannot continue to move outward, thereby restricting the coke distance reference member 200 from detaching from the body 100.

[0046] See Figures 3 to 4 In some embodiments, a sleeve 122 is installed in the guide hole 121, and the pull rod 220 is slidably fitted into the sleeve 122.

[0047] Specifically, the sleeve 122 is fixedly installed inside the guide hole 121, and the shape and size of its inner ring match the rod body 221 of the pull rod 220, so that the rod body 221 can slide and engage with the sleeve 122. Thus, during the extension and retraction of the reference piece 200, the sleeve 122 can guide and limit its movement, enhancing the smoothness of the sliding process and preventing it from wobbling. In other embodiments, the sleeve 122 can be omitted, and the shape and size of the guide hole 121 can match the rod body 221, allowing the rod body 221 to slide and engage with the guide hole 121.

[0048] Preferably, in some embodiments, a rubber ring is installed inside the sleeve 122, and the pull rod 220 is slidably fitted to the rubber ring.

[0049] Specifically, the rubber ring is fixedly installed inside the sleeve 122. The rubber ring can be made of rubber or silicone, and the rod 221 slides in fit with the rubber ring. During the extension and retraction of the coke distance reference 200, the friction between the rubber ring and the rod 221 allows the coke distance reference 200 to be stably maintained in its current position, preventing it from shaking.

[0050] See Figures 3 to 4 In some embodiments, the guide 120 is provided with a clearance groove 123 at one end near the handle 210; and / or, the handle 210 is provided with a clearance groove at one end near the pull rod 220.

[0051] In the above embodiments, by providing the avoidance groove 123, a gripping space can be provided when the operator grips the handle 210, so as to facilitate operation.

[0052] See Figure 4 In some embodiments, the guide 120 has a slot 124 for mounting an accessory.

[0053] Specifically, slot 124 has an opening for inserting or removing attachments. Slot 124 is a blind slot; therefore, when guide 120 is inserted into slot 124, the front end of guide 120 touches the slot wall, indicating that it is properly installed. This serves as a prompt and effectively positions guide 120. In the embodiment shown in the figures, the opening of slot 124 is L-shaped, meaning that openings are provided on both adjacent surfaces of guide 120, facilitating the insertion and removal of attachments. In other embodiments, an opening may be provided only on one surface of guide 120. By inserting different attachments, the performance of digital X-ray imaging equipment can be enhanced in various ways. For example, when an attachment such as an additional filter is used for image correction of a flat panel detector, it can improve image uniformity.

[0054] See Figures 2 to 5 In some embodiments, the locking mechanism includes a first magnetic part 125 and a second magnetic part 211 with opposite magnetic properties. The first magnetic part 125 is disposed on the body 100, and the second magnetic part 211 is disposed on the focal distance reference member 200. When the focal distance reference member 200 retracts, the first magnetic part 125 and the second magnetic part 211 are magnetically attracted to each other. Thus, in the later stage of the focal distance reference member 200 retraction process, the magnetic attraction between the first magnetic part 125 and the second magnetic part 211 can accelerate the retraction of the focal distance reference member 200. At the same time, after the focal distance reference member 200 is retracted, it can be locked to the body 100 to prevent it from stretching again, thereby keeping the body assembly stably in a small size, making it easy to carry and store.

[0055] Alternatively, in some embodiments, the locking mechanism includes a third magnetic part 223 and a metal part, one of which is disposed on the body 100 and the other on the focal distance reference member 200. When the focal distance reference member 200 retracts, the third magnetic part 223 and the metal part are magnetically connected. Thus, in the later stage of the focal distance reference member 200 retraction process, the magnetic attraction between the third magnetic part 223 and the metal part can accelerate the retraction of the focal distance reference member 200. At the same time, after the focal distance reference member 200 is retracted, it can be locked to the body 100 to prevent it from elongating again, thereby keeping the body component stably in a small size, making it easy to carry and store.

[0056] Alternatively, in some embodiments, the two embodiments described above can be combined, that is, not only the first magnetic part 125 and the second magnetic part 211 are provided, but also the third magnetic part 223 and the metal part are provided, so as to further enhance the magnetic attraction force, so that the focal distance reference member 200 can complete the retraction action more quickly when retracting, and can be more firmly locked to the body 100 after retraction.

[0057] See Figures 2 to 5 In some embodiments, the guide member 120 has a first magnetic part 125 on the end face facing the focal distance reference member 200, and the focal distance reference member 200 has a second magnetic part 211 on the end face facing the guide member 120.

[0058] Specifically, a second magnetic part 211 is provided on the end face of the handle 210 near the pull rod 220. When the focal distance reference member 200 is retracted, the handle 210 can be magnetically attracted and limited by the first magnetic part 125 on the guide member 120, so that the entire focal distance reference member 200 can be locked to the body 100 after retraction.

[0059] In some embodiments, of the third magnetic part 223 and the metal part, one is disposed in the sliding channel, and the other is disposed at one end of the focal distance reference member 200 that extends into the sliding channel.

[0060] Specifically, of the third magnetic part 223 and the metal part, one is disposed in the sliding channel, and the other is disposed at the end of the lever 220 away from the handle 210.

[0061] In the embodiment shown in the accompanying drawings, the third magnetic part 223 is disposed at the end of the pull rod 220 away from the handle 210, and the metal part is disposed within the sliding channel. In other embodiments, these can be interchanged. In the above embodiment, when the focal distance reference piece 200 retracts, not only does the handle 210 magnetically retain itself via the first magnetic part 125 on the guide 120, but the metal part within the sliding channel inside the body 100 is also magnetically attracted via the third magnetic part 223 at the end of the pull rod 220, thereby ensuring that the entire focal distance reference piece 200 is more securely locked to the body 100 after retraction.

[0062] In the aforementioned embodiments, the focal distance reference component 200 is locked in position via magnetic connection after retraction. In other embodiments, position locking can also be achieved through snap-fit ​​or other methods. For example, the locking mechanism includes a first snap-fit ​​part and a second snap-fit ​​part. The first snap-fit ​​part is disposed on the body 100, and the second snap-fit ​​part is disposed on the focal distance reference component 200. When the focal distance reference component 200 is retracted, the first snap-fit ​​part and the second snap-fit ​​part snap together. The first snap-fit ​​part and the second snap-fit ​​part can be of any snap-fit ​​form; for example, one can be a snap block, and the other a snap slot.

[0063] See Figures 2 to 5In some embodiments, the handle 210 is connected to a plurality of spaced-apart pull rods 220, and the guide member 120 has a plurality of guide holes 121 corresponding one-to-one with the plurality of pull rods 220. The base 110 is provided with a plurality of sliding channels corresponding one-to-one with the plurality of pull rods 220. Each pull rod 220 passes through the corresponding guide hole 121 and slides into the corresponding sliding channel. In this way, the smoothness of the sliding process of the focal distance reference member 200 can be further improved.

[0064] See Figures 2 to 5 In some embodiments, the focal distance reference 200 includes multiple sets of mating handles 210 and pull rods 220. For example, in the embodiment shown in the figures, two sets of mating handles 210 and pull rods 220 are provided. By providing multiple sets of the above-described structures, distance reference is more convenient during patient position adjustment.

[0065] See Figures 1 to 2 The digital X-ray imaging device provided in one embodiment of this application includes the body components of the digital X-ray imaging device in any of the foregoing embodiments.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
