[0031] The present utility model aims to provide a scanning table handle and a scanning table suitable for use in examinations using medical equipment such as computed tomography (CT), positron emission tomography (PET), positron emission computed tomography (PET-CT), and magnetic resonance imaging (MR). The handle addresses issues with existing scanning tables, such as unsightly operation buttons, inaccurate keypresses, and a lack of user feedback. The following description provides a more detailed description with reference to the accompanying drawings.

[0032] like Figures 1 to 6 As shown, an embodiment of the present invention provides a scanning table, which includes a scanning table handle 200 and a bed plate 20. The scanning table handle 200 is detachably mounted on the rear end of the bed plate 20. In some cases, the scanning table further includes a headrest 30, which is detachably mounted on the front end of the bed plate 20.

[0033] Key References Figures 1 to 3 As shown, in an exemplary embodiment, the scanning bed handle 200 is detachably fixed to the base 100. Generally, the scanning bed handle 200 is fixed to an end of the base 100 away from the bed plate 20 (i.e., the rear end). The scanning bed handle 200 allows the user to drag the scanning bed to move.

[0034] The base 100 is typically an existing structure on a scanning bed. For example, in this embodiment, the scanning bed further includes a column 40, and the base 100 covers the top of the column 40, and the bed plate 20 can be driven to rise and fall along the column 40. However, the present invention is not limited to this.

[0035] In other embodiments, a lifting device, such as a fork-type lifting device, is provided at the bottom of the bed board 20 to enable the bed board 20 to be raised and lowered. In this case, the scanning bed handle 200 can also be removably secured to the rear end of the bed board 20. Typically, the rear end of the bed board 20 extends into the base 100 and is removably secured thereto. In this case, the base 100 can be configured as a shell structure, covering the rear end of the bed board 20.

[0036] Continue to refer Figure 3 The scanning bed handle 200 includes a handle housing 210 , a sensor 220 and an indicator 230 .

[0037] The sensor 220 is installed in the handle housing 210, and its function is to detect the gripping state of the handle housing 210, so as to perform function unlocking according to the gripping state of the handle housing 210 and simultaneously give clear function unlocking feedback.

[0038] Function unlocking typically refers to unlocking the device to interrupt scanning. Function unlock feedback refers to outputting a corresponding prompt message. In practice, one or a combination of prompt messages may be output. The specific form of the prompt message is not particularly limited, and may include, for example, a light prompt, a vibration prompt, or a voice prompt. Preferably, the prompt message uses a light prompt, which is more eye-catching and intuitive.

[0039] Specifically, the prompt information is outputted through the indicator 230. However, the present application has no special restrictions on the installation position of the indicator 230.

[0040] For example, Figure 1 、 Figures 2 and 3 and Figure 6In the exemplary embodiment described, the indicator 230 is provided separately from the handle housing 210. That is, the indicator 230 is not mounted on the handle housing 210 and can be mounted anywhere on the scanning bed other than the handle housing 210. Further preferably, the indicator 230 is mounted on the base 100, preferably in a detachable manner.

[0041] Alternatively, Figure 5 In another exemplary embodiment described, the indicator 230 is integrated with the handle housing 210 , that is, the indicator 230 is directly mounted on the handle housing 210 , and the mounting method is preferably detachable.

[0042] Of course, the installation location of the indicator 230 includes but is not limited to the locations disclosed in the above embodiments. In practice, any location is sufficient as long as the indicator 230 can provide clear functional feedback. It should also be understood that when the indicator 230 is used to output vibration, it is preferably installed on the handle housing 210 so that the user can directly feel the vibration when holding the handle housing 210. When the indicator 230 is used to output a light prompt, it should be located within the user's field of view so that the user can directly see it.

[0043] To this end, the sensor 220 is connected to the indicator 230 via a cable, so that the indicator 230 can output corresponding prompt information according to the status of the sensor 220.

[0044] In another aspect, the sensor 220 is also connected to a functional device of the scanning bed via a cable, so that the functional device can unlock the device and interrupt the scanning process based on the status of the sensor 220. Here, the functional device should be understood as a functional braking part that can quickly interrupt the scanning process in an emergency.

[0045] The working principle of the scanning bed handle 200 is as follows: when it is necessary to interrupt scanning, the user can hold the handle housing 210 with one or both hands, thereby triggering the sensor 220, causing the sensor 220 to output a corresponding signal to the indicator 230 and the functional device, thereby activating the braking function of the device and providing clear functional feedback; conversely, when not in use, the user only needs to leave the handle housing 210.

[0046] It can be seen that the scanning bed provided in this application has eliminated the external operation buttons in appearance. The operation buttons are mainly buttons for unlocking the security function of the device (such as the Floating button), and the function of unlocking the device is integrated into the scanning bed handle 200. In this way, the overall aesthetics of the scanning bed can be improved, and the user operation is convenient, and clear functional feedback can be obtained, which increases the accuracy of the operation and improves the operating experience.

[0047] In addition, one or more sensors 220 may be disposed within the handle housing 210, preferably multiple sensors 220. The multiple sensors 220 are independently disposed within the handle housing 210. By disposing multiple sensors 220, the present application can effectively increase the sensitivity of sensing, thereby ensuring the effectiveness and reliability of the sensing operation.

[0048] The sensor 220 may be a photoelectric sensor, but is not limited to a photoelectric sensor. For example, a piezoelectric sensor, an inductor, a temperature sensor, or other types of position sensors may also be used, and one or a combination of multiple types thereof may be used.

[0049] In order to increase the sensing coverage area, the plurality of sensors 220 are preferably arranged in sequence along the length direction of the handle housing 210 (see Figure 4 ), such as, equidistant arrangement or non-equidistant arrangement. In this way, the user can trigger functions at different positions of the operation sensing area of ​​the handle housing 210, with high sensitivity.

[0050] Further preferably, the plurality of sensors 220 are arranged at equal intervals along the length direction of the handle housing 210 so that a function can be triggered at any position in the operation sensing area, resulting in a better sensing effect.

[0051] Specifically, the number of the sensors 220 may be two, three, or more. In this embodiment, there are three sensors 220, which can meet the requirements of the sensing coverage area, ensure sensing sensitivity, and save costs to a certain extent.

[0052] On the other hand, this application reduces wiring difficulty by optimizing internal routing, while avoiding functional problems and ensuring reliability and effectiveness of use.

[0053] Please refer to Figure 3 As shown, in some embodiments, the handle housing 210 includes a detachably connected upper cover 211 and a base 212. Preferably, the upper cover 211 and the base 212 are fixed by screws.

[0054] Next, please refer to Figure 2 As shown, when installing the scanning bed handle 200, in some embodiments, a mounting space 101 is provided on one side (preferably at the rear end) of the base 10; the scanning bed handle 100 is directly mounted in the mounting space 101; and the base 212 is detachably connected to the base 100 at both ends along the length of the handle housing 210, preferably secured with screws. This arrangement improves the aesthetics of the entire scanning bed.

[0055] Return Reference Figure 3The base 212 is provided with a mounting surface 213 facing the upper cover 211; one or more sensors 220 are provided on the mounting surface 213. Thus, the sensors 220 mainly detect the gripping state of the upper cover 211.

[0056] Furthermore, the base 212 is further provided with a wiring trough 214 for routing cables, which extends from the mounting surface 213 to the exterior of the base 212. Specifically, the wiring trough 214 extends through the base 212, allowing cables within the handle housing 210 to be led out to the exterior and connected to functional devices. In some cases, the cables led out to the exterior may also need to be connected to the indicator 230.

[0057] It should be noted that the present application does not limit the path selection of the wiring groove 214. Generally, it only needs to not affect the appearance, the covering of the upper cover 211 and the base 212, and the photoelectric sensing.

[0058] Figure 3 In the exemplary embodiment described, a wiring trough 214 is provided on the side of the base 212 facing away from the base 100 (i.e., at the rear end) along the closing direction of the upper cover 211 and the base 212. All cables extending from the sensors 230 are routed through the wiring trough 214 and led out to the bottom of the handle housing 210. In some cases, the cables extending to the outside enter the interior of the column 40 and connect to the functional device, while the cables extending to the outside extend along the bottom of the base 100 and connect to the indicator 230 on the base 100.

[0059] Figure 4 In another exemplary embodiment, a wiring trough 214 is directly formed on the mounting surface 213. A wiring trough 214 is also reserved between one side (i.e., the rear end) of the mounting surface 213 and the rear wall 215 of the base 212, extending along the closing direction of the upper cover 211 and base 212. This allows internal cables to be routed to the outside through the corresponding wiring trough 214 without affecting aesthetics or functionality.

[0060] Of course, the path selection of the wiring trough 214 can be adjusted and changed according to actual conditions and needs, and is not limited to the content disclosed in the above embodiment.

[0061] As mentioned above, the upper cover 211 and the base 212 are preferably fastened by screws. Figure 3 and Figure 4As shown, in some optional embodiments, the base 212 is provided with a flange 216 on each side of the mounting surface 213 along the length of the handle housing 210. Both flanges 216 have screw holes 217. This allows the two flanges 216 to be secured to the upper cover 211 via screws, resulting in a simple structure and easy assembly and disassembly. The number of screw holes 217 on each flange 216 includes, but is not limited to, one. For aesthetic reasons and ease of operation, preferably, each flange 216 has only one screw hole 217.

[0062] like Figure 4 As shown, the mounting surface 213 is preferably provided with a positioning groove 218 for placing the sensor 220. In actual manufacturing, the mounting surface 213 is grooved to form the positioning groove 218, or an annular wall is extended on the mounting surface 213, and the inner cavity of the annular wall serves as the positioning groove 218.

[0063] Preferably, the shape of the positioning groove 218 is adapted to the shape of the sensor 220. This arrangement can not only position the sensor 220, but also play a fool-proof role to avoid installation errors, while optimizing cable routing to avoid functional problems.

[0064] Based on this, a sensor 220 capable of providing a foolproofing function can be selected. For example, the more common sensor 220 has a positioning feature that can achieve a foolproofing function. The positioning groove 218 correspondingly has a positioning groove wall 219 that cooperates with the positioning feature. The form of the positioning feature is not limited. For example, while this embodiment uses an oblique angle, in other embodiments, any shape such as a rounded corner, a notch, or a mark or combination thereof can also be used, as long as the same effect is achieved.

[0065] Continue to refer Figure 4 In a preferred embodiment, there are multiple positioning grooves 218, and the multiple positioning grooves 218 are arranged in sequence along the length direction of the base 212. A sensor 220 is placed in each positioning groove 218, and the positions of the positioning groove walls 219 of at least some of the positioning grooves 218 are different, in order to optimize the cable routing and avoid functional problems.

[0066] Taking three sensors 220 as an example, the three sensors 220 are arranged at equal distances, and the assembly direction of one sensor 220 is opposite to that of the other two sensors 220, so that the cable of the sensor 220 near the edge just avoids the position where the upper cover 211 and the base 212 overlap, which facilitates wiring.

[0067] Preferably, a wiring groove 214 is provided between two adjacent positioning grooves 218, and the positioning groove walls 219 of the positioning grooves 218 are arranged adjacent to the corresponding wiring grooves 214, so that it is convenient for the sensor 220 to lead out the cable at the position of the positioning feature (such as the bevel). Here, for ease of understanding, Figure 4 The dotted line indicates the cable lead-out direction.

[0068] It should be further explained that there are many ways to mechanically prevent the sensor 220 from being misplaced. Although the embodiment of the present application is described in combination with the misplacement prevention method of the bevel, it should be understood that various other misplacement prevention methods of mechanical structures can also be used. Therefore, in addition to the misplacement prevention methods listed in the accompanying drawings, technical personnel in the relevant field can find other alternative methods based on the records of the specification of this application to achieve the functions recorded in this application / achieve the above-mentioned effects, not just the solutions disclosed in this embodiment.

[0069] The implementation of the indicator 230 is further described below.

[0070] The indicator 230 is at least one of a light indicator, a voice indicator, and a vibration indicator. In this embodiment, the indicator 230 is a light indicator.

[0071] The indicator 230 can be white or other colors, preferably white. Specifically, when the scanner bed handle 200 is in use, the indicator 230 lights up when the handle housing 210 is held. When not in use, the indicator 230 lights up when the hand leaves the handle housing 210.

[0072] like Figure 3 As shown, in a preferred embodiment, the indicator 230 includes a light source 231 and a light guide structure 232, and the two are used in combination to achieve a better lighting prompt effect. The light source 231 is arranged outside or inside the light guide structure 232, and the light source 231 is connected to the sensor 220 via a cable. Optionally, the light source 231 is a light bar, and the light guide structure 232 is a light guide column. The light source 231 is usually directly installed at the bottom of the lamp trough 102, and the light guide structure 232 can guide light to improve the lighting effect. In other cases, the indicator 230 may also include only the light source 231, without the light guide structure 232.

[0073] To fix the indicator 230, the scanning bed handle 200 further includes an indicator mounting member 240. The indicator 230 is disposed on the indicator mounting member 240, which is detachably connected to at least one of the base 100 and the handle housing 210, preferably by screw fixing.

[0074] Please refer to Figures 2 and 3 and Figure 6As shown, to avoid affecting the appearance, the indicator mounting member 240 is disposed at the bottom of the base 100, or in other words, the indicator mounting member 240 is disposed on the inner side of the base 100. Furthermore, a light trough 102 is provided on the side of the mounting space 101 facing the handle housing 210, and the light source 231 is mounted at the bottom of the light trough 102. Optionally, the indicator 230 also includes a lampshade. The light source 131, light guide structure 232, and lampshade are disposed in sequence, with the lampshade exposed and directly visible.

[0075] Or, as Figure 5 As shown, the indicator 230 is directly mounted on the handle housing 210 for prompting. The indicator 230 is preferably mounted on the upper cover 211 of the handle housing 210, and more particularly, is disposed on the top surface of the upper cover 211, allowing the user to directly view the light prompt. In this case, the light source 231 of the indicator 230 is mounted in a light groove of the handle housing 210, and the indicator 230 is fixed in any suitable manner, which is not limited by this application.

[0076] In summary, the present application provides a scanning bed and a scanning bed handle 200 thereof. The scanning bed handle 200 is internally equipped with a sensor 220 that combines an unlocking function (such as a floating function) with a feedback function. In actual use, when the user grips the handle housing 210, the braking function is unlocked. Once the braking function is unlocked, the scanning process can be interrupted. This configuration improves the overall aesthetics of the scanning bed and facilitates user operation. Users also receive clear functional feedback during operation, increasing operational accuracy and enhancing the user experience.

[0077] Secondly, the present application also allows for adjusting the sensitivity of the sensors 220, for example by increasing the number of sensors 220 or adjusting the arrangement direction and spacing of the multiple sensors 220, thereby increasing the sensing coverage area. Consequently, when a user naturally grips the handle housing 210 with both hands or one hand to drag the scanning bed, the applied force can be reduced and evenly distributed, and functions can be triggered at any position within the handle's operating sensing area.

[0078] In addition, since the positioning groove 218 on the base 212 is designed according to the shape of the sensor 220, a fool-proof function is achieved, which can effectively prevent incorrect installation of the production line and improve work efficiency.

[0079] Furthermore, the combination of the positive and negative arrangement of the multiple sensors 220 and the fool-proof design not only limits the installation direction of the sensors 220 but also optimizes the routing of the cables, thereby effectively avoiding functional problems.

[0080] While the present invention is disclosed above, it is not limited thereto. Persons skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the present invention and its equivalents, the present invention is intended to encompass such modifications and variations.
