[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] The CT / PET bed is a key piece of equipment for achieving precise patient positioning and completing scanning diagnoses. Its horizontal structure must ensure reliable installation and fixation of the bed board and moving parts, and allow for horizontal movement relative to the guide rails on the fixed frame to accommodate patient position adjustments during the scanning process. However, traditional guide rails are designed with exposed surfaces, lacking effective protection and prone to rust.

[0042] To address the aforementioned issues, this application provides a bed board covering device and a patient support device. By including a covering assembly, during the reciprocating motion of the bed board in a first direction, the covering assembly can continuously and uninterruptedly cover the guide rail area above the fixing frame and the gap between the bed board and the fixing frame, preventing external dust, impurities, liquids, and other contaminants from entering the guide rail or gap. This effectively prevents the guide rail from jamming or corroding due to contamination, ensuring the smoothness and precision of the bed board's movement.

[0043] The following will combine Figures 1 to 7 The specific structure of the patient support device provided in the embodiments of this application will be described.

[0044] Reference Figure 1 and Figure 5 As shown, this application embodiment provides a patient support device 200, including a bed frame, a bed board 210, a height adjustment component, and a horizontal adjustment component. The bed board 210 is located on the bed frame, the height adjustment component is disposed on the bed frame and configured to drive the bed frame to move up and down; the horizontal adjustment component is located inside the bed frame and configured to drive the bed board 210 to move horizontally.

[0045] In order to effectively cover the guide rails and gaps during the movement of the bed board 210, this embodiment also includes a bed board covering device 100. The bed board covering device 100 is connected to the bed board 210. When the bed board 210 moves, the covering component 120 of the bed board covering device 100 moves synchronously with the bed board 210.

[0046] The bed board 210 is a structure that supports the patient and can move along a first direction, which is horizontal. For example, the first direction can move to the left or to the right. This embodiment mainly uses movement to the left as an example for explanation; for details, please refer to [reference needed]. Figure 1 As indicated by the middle arrow a.

[0047] The movement of the bed board 210 can be driven by external power. For example, the bed board 210 can be driven by a motor or a push rod.

[0048] The specific structure of the bed board covering device provided in the embodiments of this application will be described below.

[0049] Reference Figure 2 and Figure 3 As shown, this application embodiment provides a bed board covering device 100, including a fixing frame 110 and a covering assembly 120. The fixing frame 110 is provided with a guide rail 111 extending in a first direction. The guide rail 111 is used to allow the bed board 210 to move in the first direction and relative to the fixing frame 110.

[0050] At least a portion of the covering assembly 120 is located above the fixing frame 110 and can form a covering area 130 along the direction of movement of the bed board 210. The front end of the covering assembly 120 is used to connect with the bed board 210, and the rear end of the covering assembly 120 is fixedly connected to the fixing frame 110.

[0051] The fixed frame 110 serves as the basic support structure, and its guide rail 111 can extend along a first direction, which can be understood as a horizontal straight line, such as the scanning direction of the bed board 210. The cover assembly 120 is pre-arranged and is at least partially located above the fixed frame 110, initially forming a cover area 130. This area corresponds to the easily exposed and protected space between the guide rail 111 and the bed board 210 and the fixed frame 110.

[0052] It is understood that the front end of the cover assembly 120 is the front end along the movement direction of the bed board 210, and the rear end of the cover assembly 120 is the rear end along the movement direction of the bed board 210, and is fixed to the fixing frame 110 in a relatively static state.

[0053] When the bed board 210 moves along the first direction, the covering assembly 120 moves synchronously with the bed board 210. During the entire process of the bed board 210 reciprocating along the first direction, the covering area 130 can dynamically adapt to the position change of the bed board 210, and achieve uninterrupted sealing and covering of the guide rail 111 and the gap between the bed board 210 and the fixing frame 110, thereby achieving continuous covering of the guide rail 111 and the gap.

[0054] In one embodiment, reference Figure 2 and Figure 4 As shown, the covering assembly 120 may include a covering cloth 121. Along the movement direction of the bed board 210, the front end 1211 of the covering cloth is used to connect with the bed board 210, and the rear end 1212 of the covering cloth is fixedly connected to the fixing frame 110.

[0055] The covering cloth 121 may be at least partially located above the fixing frame 110 and form a covering area 130; or the covering cloth 121 may be entirely located above the fixing frame 110. This embodiment does not limit this.

[0056] It should be noted that during the design process, space generally needs to be reserved for cable routing to ensure that the cables can be smoothly passed through the bed board 210. For example, a cable channel can be provided on the fixing frame 110, and a slot can be designed on the side or bottom of the moving part 140 to fix and guide the cables; a certain distance is reserved between the covering cloth 121 and the fixing frame 110 to form a channel for the cables to pass through. In this way, the cable is led out from the fixing frame 110, guided along the side of the guide rail 111, enters the cable channel of the moving part 140, and finally connects to the bed board 210 through the channel. This embodiment does not limit this; the specific configuration can be made according to actual needs.

[0057] The connection method between the bed board 210 and the covering cloth 121 is not limited. For example, they can be connected by a connecting structure such as a clip, hook, or adhesive. When the bed board 210 moves along the first direction, the bed board 210 drives the front end 1211 of the covering cloth to move synchronously, while the rear end 1212 of the covering cloth remains stationary, thereby forcing the covering cloth 121 to undergo stretching or contraction deformation. It should be noted that during the deformation process, the covering cloth 121 always lies flat above the fixing frame 110, maintaining continuous coverage of the guide rail 111 and the gaps.

[0058] It should be noted that the covering fabric 121 needs to be both flexible and tensile. It must have sufficient flexibility to accommodate the stretching or contraction of the bed board 210 during movement, and it must also have a certain tensile strength to avoid tearing caused by frequent deformation. For example, the covering fabric 121 can be made of polyurethane coated fabric, industrial nylon woven fabric, etc., and this embodiment does not limit it.

[0059] By using a covering cloth 121, a seamless cover is formed over the gaps between the guide rail 111 and the bed board 210 and the fixing frame 110, effectively preventing dust and liquid from entering. Compared to partial covering, this minimizes the jamming and other issues caused by contamination of the guide rail 111, ensuring the movement accuracy of the bed board 210 and extending the equipment's lifespan. Furthermore, the covering cloth 121 makes flexible contact with both the fixing frame 110 and the bed board 210, reducing frictional resistance during movement and extending the equipment's service life.

[0060] In one embodiment, reference Figure 2 and Figure 3 As shown, the covering assembly 120 may include a plurality of guide rollers 122, which are arranged at intervals along the first direction on the movement path of the covering cloth 121; when the bed board 210 moves along the first direction, the covering cloth 121 drives the guide rollers 122 to rotate synchronously.

[0061] The number of guide rollers 122 is not limited. For example, there may be two, three, four or more guide rollers 122. In this embodiment, four guide rollers 122 are used as an example for explanation. In addition, the arrangement of the guide rollers 122 is not limited.

[0062] By setting guide rollers 122, the sliding friction between the covering cloth 121 and the structure it contacts is transformed into rolling friction, which significantly reduces resistance and prevents the covering cloth 121 from getting stuck or worn due to excessive friction.

[0063] In one embodiment, reference Figure 2 As shown, the guide roller 122 includes a plurality of first rollers 1221. The first rollers 1221 are arranged on the side of the cover cloth 121 away from the fixing frame 110, and the outer peripheral surface of the first rollers 1221 rolls in contact with the outer surface of the cover cloth 121.

[0064] In this embodiment, the example mainly includes two first rollers 1221.

[0065] The first roller 1221 applies rolling support force from the outside of the cover cloth 121, forming an inner and outer clamping effect with the fixing frame 110, which helps to prevent the cover cloth 121 from twisting due to unilateral force and improves the stability of the guide.

[0066] In one embodiment, reference Figure 2 As shown, the guide roller 122 also includes a plurality of second rollers 1222, which are arranged on the side of the cover cloth 121 near the fixing frame 110, and the outer peripheral surface of the second rollers 1222 makes rolling contact with the inner surface of the cover cloth.

[0067] In this embodiment, the example mainly includes two second rollers 1222.

[0068] The second roller 1222 applies rolling support force from the inside of the covering fabric 121. The second roller 1222 and the first roller 1221 clamp the covering fabric synchronously from the inside and outside, ensuring that the covering fabric 121 remains in a stable balance during movement, reducing the risk of lateral displacement caused by unilateral force. Moreover, the rollers on both sides provide uniform support for the thin fabric, preventing wrinkles caused by the softness of the material and extending the service life of the covering fabric 121.

[0069] The multiple first rollers 1221 and multiple second rollers 1222 can be alternately arranged along the first direction. It should be noted that the alternating arrangement means that the outer first rollers 1221 and the inner second rollers 1222 are staggered along the direction of movement, forming an outer-inner-outer-inner cyclic layout pattern.

[0070] By adopting an alternating arrangement, the covering cloth 121 is always supported by at least one side of the rollers throughout the entire movement, further avoiding the problem of local suspension caused by excessive spacing between the rollers on one side, thereby ensuring the coverage stability of the ultra-long stroke.

[0071] Alternatively, the multiple first rollers 1221 and multiple second rollers 1222 can be arranged along both sides; or, the multiple first rollers 1221 and multiple second rollers 1222 can also be arranged symmetrically. Symmetry is not limited in this embodiment, and can be set according to actual needs.

[0072] In one embodiment, reference Figures 2 to 4 As shown, it may also include a moving component 140, which is embedded in the guide rail 111. The bed board 210 is fixedly connected to the moving component 140 and moves synchronously. At least part of the covering cloth 121 covers the moving component 140, and the guide roller 122 is located on top of the moving component 140, forming a support state for the covering cloth 121. When the bed board 210 moves relative to the fixed frame 110 through the moving component 140, the moving component 140 pulls the covering cloth to move synchronously.

[0073] The connection method between the bed board 210 and the moving part 140 is not limited. For example, a permanent magnet can be embedded in the top of the moving part 140, forming an adsorption fixation with the magnetic plate at the bottom of the bed board 210. Traction force is transmitted through magnetic field coupling, completely physically isolating the covering cloth 121. Alternatively, the moving part 140 can engage with the bottom edge of the bed board 210 via side buckles, with the connecting cloth located outside the area covered by the covering cloth 121, without needing to penetrate the cloth surface. This embodiment does not limit this approach.

[0074] The sliding engagement method between the moving part 140 and the fixed frame 110 is not limited. For example, refer to... Figure 3 and Figure 4As shown, the moving part 140 may include a moving body 141 and a protrusion 142 disposed on the moving body 141. The protrusion 142 is embedded in the guide rail 111 so that the moving part 140 slides relative to the fixed frame.

[0075] It should be noted that the connection method between the guide roller 122 and the covering cloth 121 is not limited. For example, the guide roller 122 and the covering cloth 121 can be connected non-contactly by magnetic coupling. This embodiment does not limit this.

[0076] By setting the guide roller 122 at the top of the moving part 140, it helps to support the covering cloth 121 at the top of the moving part 140, converting the sliding friction between the covering cloth 121 and the moving part 140 into rolling friction, thus reducing the resistance to movement. Moreover, the rotation of the roller can absorb minor vibrations, ensuring that the covering cloth 121 unfolds or retracts without jamming.

[0077] In one embodiment, reference Figure 4 As shown, the covering cloth 121 covers the gap between the moving part 140 and the fixed frame. For example, if it is a flexible covering cloth, it hangs down from the edge of the moving part 140 and covers the gap on the upper surface of the fixed frame; if it is a rigid covering cloth, it is placed between the bottom of the moving part 140 and the top of the fixed frame to cover the gap between the two.

[0078] In one embodiment, reference Figure 5 As shown, the cover assembly 120 may include a cover plate 123 along the movement direction of the bed board 210. The front end 1231 of the cover plate is used to connect with the bed board 210, and the rear end 1232 of the cover plate is fixedly connected to the guide rail 111.

[0079] Among them, reference Figure 5 As shown, a first covering area 131 is formed above the cover plate 123 and the fixing frame 110, and a second covering area 132 is formed above the bed board 210 and the fixing frame 110. The first covering area 131 and the second covering area 132 together form the covering area 130.

[0080] It should be noted that the difference between this embodiment and the previous embodiment is that the previous embodiment only covered the top of the fixing frame 110 with the covering cloth 121, that is, it covered the entire fixing frame 110; in this embodiment, the bed board 210 also covers the top of the fixing frame 110, that is, a combined covering scheme of bed board 210 and covering plate 123 is adopted, and through the synergistic effect of the two, segmented coverage of the top of the fixing frame 110 is achieved.

[0081] Additionally, it should be noted that the aforementioned embodiment converts the sliding friction between the cover cloth 121 and the moving part 140 into rolling friction, thereby reducing motion resistance. This embodiment includes a cover plate 123 and employs linear bearings to reduce the motion resistance of the multi-layer board. Both embodiments can effectively reduce resistance during movement and ensure smooth motion.

[0082] The above-described configuration is applicable to long-stroke motion scenarios, avoiding the incomplete coverage problem caused by stretching of a traditional single cover cloth 121. Furthermore, the combination of the bed board 210 and the cover plate 123 reduces reliance on the flexible cover cloth 121, providing stable coverage support and helping to resist deformation from external forces. For example, the cover cloth 121 can be made of a rigid material, such as aluminum alloy or carbon fiber; this embodiment does not limit this choice.

[0083] In one embodiment, reference Figure 6 and Figure 7 As shown, the number of cover plates 123 can be multiple, and the multiple cover plates 123 are interconnected; when the bed board 210 moves along the first direction, the multiple cover plates 123 move in coordination to form a continuous covering state on the extension path of the guide rail 111.

[0084] It should be noted that "interlocking connection" means that the multiple cover plates 123 do not move independently, but form an integral structure through a mechanical connection. When one of the cover plates 123 is dragged, this linkage mechanism will transmit the movement to all the other cover plates 123 in sequence, ensuring that they move in coordination according to the preset rules and jointly complete the action of extending or retracting.

[0085] For example, multiple cover plates 123 can be connected in a stepped, staggered manner along the first direction. Alternatively, multiple cover plates 123 can be connected in a combination of smooth and linked operation. As long as two adjacent cover plates 123 do not overlap and are seamlessly connected to form a covering state, they are all within the protection scope of this application.

[0086] For example, the bed board 210 and the cover panel 123 closest to it can be connected by a traction mechanism, such as a steel wire rope. It is understood that when the bed board 210 moves, the traction mechanism drives all the cover panels 123 to move synchronously and differentially. Specifically, when unfolded, refer to... Figure 6 As shown, each cover plate 123 extends gradually; when retracting, refer to... Figure 7 As shown, a reverse progressive overlapping design is adopted. It should be noted that through the stepped overlapping design, when the panels are folded together, the adjacent cover plates 123 have a certain height difference, thereby avoiding mutual interference.

[0087] In one embodiment, reference Figure 6As shown, each cover plate 123 may include a bracket 1233 and a cover body 1234 disposed at the top of the bracket 1233. The two ends of the cover body 1234 extend outward along the first direction to form connecting portions 1235. Along the movement direction of the bed board 210, the connecting portion 1235 at the rear end of the front cover plate 123 is connected to the connecting portion 1235 at the front end of the rear cover plate 123.

[0088] It should be noted that the specific structure of the connecting part 1235 is not limited. For example, the connecting part 1235 can be a snap-fit, with the front and rear cover plates 123 snapped together; or, the connecting part 1235 can be a magnetic structure, with the front and rear cover plates 123 magnetically connected; or, the connecting part 1235 can be a hinge, with the front and rear cover plates 123 hinged together; or, the connecting part 1235 can be a sliding groove; or, the front and rear cover plates 123 can also be connected by an electronic control. This embodiment does not limit this, and the specific choice can be made according to the actual situation.

[0089] The bracket 1233 serves as a support base and is vertically fixed to the fixing frame 110, providing a stable installation reference for the cover body 1234 and ensuring that the cover body 1234 is always at a preset height. The top of the bracket 1233 is horizontally positioned on the cover body 1234, and its coverage area corresponds to the areas that need to be protected, such as the guide rail 111 and gaps. The connecting part 1235 extends outward from the cover body 1234. It can be understood that adjacent cover plates 123 are engaged through the front and rear connecting parts 1235 to form a continuous transmission chain.

[0090] The bed board covering device provided in this application embodiment includes a covering component. During the reciprocating motion of the bed board in the first direction, the covering component can continuously and uninterruptedly cover the guide rail area above the fixed frame and the gap between the bed board and the fixed frame, preventing external dust, impurities, liquids and other contaminants from entering the guide rail or gap. This effectively prevents the guide rail from getting stuck or corroded due to contamination, ensuring the smoothness and accuracy of the bed board's movement.

[0091] 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.

[0092] The above embodiments merely illustrate 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.
