[0029] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0030] Furthermore, in this application, directional terms such as "upper," "lower," "left," and "right" may be defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms can be relative concepts, used for relative description and clarification, and may change accordingly depending on the orientation of the components in the accompanying drawings.

[0031] In this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, the term "coupled" can refer to an electrical connection that enables signal transmission.

[0032] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0033] This embodiment provides a contactless medical display device based on media-free holography, which will be described in detail below.

[0034] Example 1

[0035] Reference Figures 1 to 5The contactless medical display device based on media-free holography includes an intermediate component and a media-free holographic projection module 20. The intermediate component includes a detection tray 10, and the media-free holographic projection module 20 is mounted above the detection tray 10. Detection images generated during medical personnel's work are displayed through the media-free holographic projection module 20. Displaying detection images in a media-free holographic form through the media-free holographic projection module 20 provides a clearer, more three-dimensional, and more intuitive image effect compared to traditional planar displays. This helps operators and testing personnel to more accurately observe and analyze the details of the test samples, improving the accuracy and efficiency of diagnosis.

[0036] Specifically, the medium-free holographic projection module 20 includes a frame 21, a controller, and an image reflection system, wherein the detection tray 10 is mounted on the frame 21, and the frame 21 and the detection tray 10 form a predetermined angle, the controller is mounted on the frame 21, and the image reflection system is mounted on the frame 21.

[0037] like Figure 2 As shown, the image reflection system includes a light source for generating a detection image, the light source including a display screen 201, and the image reflection system also includes an optical waveguide plate 202 for refracting the image on the display screen to form a medium-free holographic image 203.

[0038] Specifically, the contactless medical display device based on media-free holography further includes at least one armrest 40, which is installed on the side wall of the frame 21. In this embodiment, the cross-section of the armrest 40 is L-shaped.

[0039] In other words, the handrail 40 has a connecting part and a moving part, wherein the moving part has an L-shaped cross-section, and the connecting part is arranged perpendicularly to the moving part and is installed on the side wall of the frame 21. This arrangement facilitates the operator to move the frame 21, thereby changing the detection area and the display angle of the results.

[0040] Example 2

[0041] The difference from Embodiment 1 is that the contactless medical display device based on media-free holography further includes an extension stage 50, which is installed on the detection tray 10 at a predetermined tilt angle. The tilt direction of the extension stage 50 gradually increases from the side close to the detection tray 10 to the side away from the detection tray 10 and is provided with a pusher. The side of the extension stage 50 away from the detection tray 10 is higher than the detection tray 10.

[0042] It is worth mentioning that the extension stage 50 is provided with at least one through hole 501. In this embodiment, the extension stage 50 is provided with two through holes 501, which are located on the two sides of the extension stage 50 away from the detection tray 10, respectively. In this way, when the operator is performing the detection work, the detection equipment can be fixed through the through holes 501 of the extension stage 50. The two through holes 501 make it convenient for the operator to fix the detection equipment in different detection positions.

[0043] In other words, this design provides operators with additional operating space to place testing tools or other auxiliary equipment. On the other hand, its tilt angle design and the through hole 501 allow operators to easily fix the testing equipment at different testing positions, ensuring the stability and accuracy of the testing process.

[0044] Example 3

[0045] Furthermore, specifically, the contactless medical display device based on media-free holography also includes a support frame 60, which is installed on the side of the detection tray 10 away from the frame 21. The support frame 60 raises the height of the detection tray 10, making it easier for operators to perform detection work.

[0046] The contactless medical display device based on media-free holography further includes a lifting assembly 80, which is mounted on the support frame 60. The lifting assembly 80 includes a trigger 81 and a lifting cylinder 82, which are connected. The trigger 81 is movably mounted on the connecting plate 71, and the lifting cylinder 82 is retractably mounted on the support frame 60. The trigger 81 can be configured as a foot pedal. In this embodiment, upon receiving an external trigger, the trigger 81 controls the lifting cylinder 82 to raise or lower the support frame 60.

[0047] Specifically, the lifting cylinder 82 is a common pneumatic component, containing a piston and an air chamber. When the cylinder is filled with air, the piston pushes upward, extending the cylinder; when the cylinder is deflated, the piston moves downward, shortening the cylinder.

[0048] When the operator presses the trigger 81 up or down, the trigger 81 controls the air inlet of the lifting cylinder 82 to open through a mechanical structure (such as a connecting rod, valve, etc.), allowing external air to enter the lifting cylinder 82. The piston pushes upward, the lifting cylinder 82 extends, thereby driving the support frame 60 to rise.

[0049] When the operator continuously steps on the trigger 81, the trigger 81 controls the air outlet of the lifting cylinder 82 to open through the mechanical structure, so that the gas in the lifting cylinder 82 is discharged, the piston moves downward, the lifting cylinder 82 shortens, thereby driving the support frame 60 to lower.

[0050] This allows operators to easily change the height of the support frame 60, thereby changing the height of the detection tray 10. Operators can flexibly adjust the height of the support frame 60 according to their height and operating habits, improving the versatility and adaptability of the equipment. Of course, the cylinder here can also be an electric actuator or an electric cylinder, and the foot pedal can be a switch-type foot pedal that triggers the electric actuator or electric cylinder to operate, etc., without limitation.

[0051] Example 4

[0052] The contactless medical display device based on media-free holography also includes a sliding component 30, which is installed between the frame 21 and the detection tray 10 to change the position of the frame 21 relative to the detection tray 10, thereby expanding the detection range.

[0053] Specifically, the sliding assembly 30 includes a slider 31, a groove 32, and a conveyor 33, wherein the groove 32 is formed in the detection tray 10, the slider 31 is mounted on the frame 21, the slider 31 is slidably mounted in the groove 32, and the conveyor 33 is installed between the slider 31 and the groove 32 for connecting the slider 31 and the groove 32.

[0054] It is worth mentioning that the conveying component 33 includes two gears 331 and a rack 332. The rack 332 is installed at the bottom of the slide groove 32, and the two gears 331 are installed on the side wall of the slider 31 in a predetermined arrangement. The two gears 331 are adapted to the rack 332, and the two gears 331 have a predetermined interval. When the slider 31 slides in the slide groove 32, the two gears 331 rotate along the rack 332, which can realize the change of the position of the frame 21 relative to the detection tray 10.

[0055] In this embodiment, when the operator pushes the frame 21, the two gears 331 on the slider 31 rotate and move along the rack 332. After moving to the designated position, the operator no longer applies force to the frame 21. At this time, the position of the frame 21 is fixed. The two gears 331 can further prevent the frame 21 from moving after its position is fixed.

[0056] In this way, the operator can push or pull the frame 21 to change the position of the frame 21 relative to the detection tray 10, thereby expanding the detection range.

[0057] Furthermore, the sliding assembly 30 also includes a driving member 34, which includes the connecting rod 341 and the handle 342. The connecting rod 341 is mounted on the slider 31, and one end of the connecting rod 341 extends out of the detection tray 10. The handle 342 is mounted on the end of the connecting rod 341 that is away from the slider 31. In this way, the operator can push or pull the handle 342, which drives the connecting rod 341 to move, thereby changing the position of the slider 31.

[0058] The frame 21 and the detection tray 10 are connected by the gear 331 and the rack 332 of the sliding component 30, which not only realizes the change of position, but also effectively prevents the frame 21 from moving after its position is fixed, thus ensuring the stability of the detection process.

[0059] Example 5

[0060] Specifically, the contactless medical display device based on media-free holography further includes a movable component 70, which is installed on the side of the support frame 60 away from the detection tray 10. The movable component 70 includes the connecting plate 71 and a plurality of the walking wheels 72. The connecting plate 71 is installed on the side of the support frame 60 away from the detection tray 10, and the plurality of the walking wheels 72 are installed on the connecting plate 71 in a predetermined arrangement.

[0061] In other words, the inclusion of the support frame 60 and the movable component 70 allows the height of the equipment to be adjusted according to the operator's height and operating habits, while also facilitating the overall movement of the equipment, thus improving its ease of use and flexibility, and making it suitable for use in different testing environments and scenarios.

[0062] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
