Description

Technical Field

[0001] This utility model relates to the field of medical instrument technology, and in particular to a scanning device. Background Technology

[0002] Blood cell testing is a routine procedure performed in hospital laboratories. Regular blood tests aid in disease diagnosis and treatment. Traditional blood testing methods used microscopes for individual analysis, which was time-consuming, labor-intensive, and prone to human error. Currently, hospitals widely use fully automated blood analyzers (hematology analyzers) for blood testing. Hematology analyzers employ photoelectric or laser technology, enabling simultaneous and automated sample introduction, dilution, blood dissolution, and report printing, significantly accelerating blood testing. However, hematology analyzers detect blood cells indirectly, lacking crucial information from morphological examination. Therefore, if the hematology analyzer results trigger morphological re-examination, the laboratory physician still needs to perform morphological analysis and diagnosis of blood cells through blood smear preparation, staining, and slide reading. Utility Model Content

[0003] Therefore, it is necessary to provide a scanning device to address the lack of blood cell morphology detection function in existing hematology analyzers.

The elastic member is disposed between the clamping arms to keep the clamping arms in a clamped state. The first stop plate is disposed at the loading position. When the planar transport assembly moves the clamping platform to the loading position, the first stop plate abuts against the first protrusion to keep the clamping arm in a released state. The second stop plate is disposed at the unloading position. When the planar transport assembly moves the clamping platform to the unloading position, the second stop plate abuts against the second protrusion to keep the clamping arm in a released state.

Detailed Implementation

[0029] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model 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 utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0030] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to 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 utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this utility model, unless otherwise explicitly 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 explicitly limited.

When 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. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0035] Addressing the limitation of existing hematology analyzers in lacking blood cell morphology detection capabilities, this application provides a scanning device. This scanning device can replace manual microscopic screening and serve as an automated detection method supplementing snowball analyzer testing.

[0036] Specifically, please refer to Figure 1 and Figure 2 The scanning device includes a loading bin, a unloading bin, a scanning transport device 10, a loading clamping device 20, a scanning detection device 30, and an unloading device 40. The loading bin stores the slides to be inspected. The unloading bin stores the inspected slides. The scanning transport device 10 includes a scanning platform 11, a planar transport component 12, and a clamping component 13. The scanning platform 11 has a loading position, an identification position, a scanning position, and an unloading position arranged sequentially. The planar transport component 12 is mounted on the scanning platform 11. The clamping component 13 is mounted on the planar transport component 12 and is used to clamp the slide. The loading clamping device 20 is located between the loading bin and the loading position and is used to clamp the slide from the loading bin onto the clamping component 13 located at the loading position. The scanning detection device 30 includes a panoramic identification component 31 and a scanning component 32. The panoramic identification component 31 is located above the identification position and is used to identify and determine the position of the slide that needs to be scanned. The scanning component 32 is located at the scanning position and is used to scan the slide. The feeding device 40 is located at the feeding position and is used to transport the glass slide from the feeding position to the feeding hopper.

[0037] It is understood that the scanning device of this application can take the glass slide to be tested from the loading bin through the loading clamping device 20, place the glass slide on the scanning platform 11, use the scanning platform 11 to transport the glass slide to the recognition position, so that the panoramic recognition component 31 can identify and judge the position to be scanned in the glass slide, and then use the scanning platform 11 to transport the glass slide to the scanning position, so that the scanning component 32 can scan the glass slide to realize the digital imaging of the glass slide tissue, obtain the glass slide inspection report, and finally transport the inspected glass slide to the unloading bin through the unloading device 40.

[0038] In this way, the scanning device of this application can automatically scan blood cell slides, realize digital image acquisition and artificial intelligence analysis of blood cell slides, and the laboratory physician only needs to manually review the test report to complete the blood cell morphology analysis process.

[0039] Furthermore, in some embodiments, the unloading position can serve as an emergency slide loading position. In other words, emergency slides can be loaded into the clamping assembly 13 through the unloading position, and then transported sequentially to the identification position and the scanning position by the planar transport assembly 12 for slide scanning. In this way, the function of emergency scanning can be satisfied simultaneously under normal scanning conditions.

[0040] Optionally, such as Figure 3 As shown, in some embodiments, the loading and gripping device 20 includes a loading lifting assembly 21, a rotating assembly 22, and a gripping assembly 23. The rotating assembly 22 is disposed on the loading lifting assembly 21, and the gripping assembly 23 is disposed on the rotating assembly 22 for gripping slides. The loading lifting assembly 21 can drive the rotating assembly 22 and the gripping assembly 23 to rise or fall, so that the gripping assembly 23 can be raised or lowered to a designated position after gripping the slide, and can also lower slides at different heights in the loading bin to different positions. The rotating assembly 22 can drive the gripping assembly 23 to rotate laterally and pitch, for secondary correction of the spatial rotation state of the slide. Usually, the rotation state of the slide is different when it arrives from the hematology analyzer production line and during scanning. By using the rotating assembly 22 to adjust the rotation attitude of the slide, the slide can achieve the required pre-scanning state.

[0041] Optionally, such as Figure 4 and Figure 5As shown, in some embodiments, the clamping assembly 13 includes a clamping platform 131, a clamping member 132, an elastic member, a first baffle 133, and a second baffle 134. The clamping platform 131 is used to place the glass slide. The bottom of the clamping platform 131 is hollowed out to facilitate illumination by a bright-field transmissive light source. The clamping platform 131 is disposed on the planar transport assembly 12, which can drive the clamping platform 131 to move in any direction on the plane, so that the clamping platform 131 can stop at the loading position, the identification position, the scanning position, and the unloading position respectively. The clamping member 132 includes a clamping arm 1321, a first protrusion 1322, and a second protrusion 1323. The clamping arm 1321 is rotatably disposed on the clamping platform 131. The first protrusion 1322 and the second protrusion 1323 protrude from the clamping arm 1321. The elastic member is disposed between the clamping arms 1321 to keep the clamping arms 1321 in a clamped state. The first baffle 133 is positioned at the loading position. When the planar transport assembly 12 drives the clamping platform 131 to the loading position, the first baffle 133 abuts against the first protrusion 1322, so that the clamping arm 1321 is in a released state. The second baffle 134 is positioned at the unloading position. When the planar transport assembly 12 drives the clamping platform 131 to the unloading position, the second baffle 134 abuts against the second protrusion 1323, so that the clamping arm 1321 is in a released state.

[0042] Thus, when the clamping platform 131 is in the loading position, the first baffle 133 abuts against the first protrusion 1322, allowing the clamping arm 1321 to be in a relaxed state. At this time, the loading clamping device 20 can place the glass slide on the clamping platform. When the clamping platform 131 leaves the loading position, the first baffle 133 disengages from the first protrusion 1322, and the clamping arm 1321 is driven into a clamping state by the elastic element, thereby clamping the glass slide. When the clamping platform 131 is in the unloading position, the second baffle 134 abuts against the second protrusion 1323, allowing the clamping arm 1321 to be in a relaxed state. At this time, the unloading device 40 can remove the glass slide from the clamping platform. In this way, through the coordinated use of the first baffle 133, the second baffle 134, the first protrusion 1322, and the second protrusion 1323, the clamping assembly 13 can be automatically opened, facilitating the loading and unloading of glass slides.

[0043] Optionally, in some embodiments, the planar transport assembly 12 may include a major axis translation assembly 121 and a minor axis translation assembly 122. The major axis translation assembly 121 is disposed on the scanning platform 11, the minor axis translation assembly 122 is disposed on the major axis translation assembly 121, and the clamping platform 131 is disposed on the minor axis translation assembly 122. The movement direction of the major axis translation assembly 121 is perpendicular to the movement direction of the minor axis translation assembly 122. In this way, through the cooperation of the major axis translation assembly 121 and the minor axis translation assembly 122, the glass slide can be moved with high precision in two directions.

[0044] Optionally, such as Figure 6 As shown, in some embodiments, the scanning component 32 includes an acquisition component 321, an oil-dispensing component 322, and an illumination component 323. The acquisition component 321 is positioned above the scanning position and can automatically scan the stained slide under a microscope. It can transmit the acquired images to an analysis unit such as a computer for image analysis, cell counting and classification, and ultimately output the cell analysis structure for analysis and diagnosis by a laboratory physician. The oil-dispensing component 322 is positioned to one side of the acquisition component 321 and is used to dispense immersion oil onto the slide to increase its transmittance, enabling the slide to meet the scanning requirements of the high-power objective lens 32142. Furthermore, the oil-dispensing component 322 can also achieve precise measurement of the immersion oil. The illumination component 323 is positioned below the scanning position and provides illumination light from below the slide so that the acquisition component 321 can acquire slide image information.

[0045] Optionally, such as Figure 6 As shown, in some embodiments, the acquisition component 321 includes a scanning lifting component 3211, a condenser component 3212, an acquisition camera 3213, and an objective lens component 3214. The acquisition camera 3213 is disposed on the emission side of the condenser component 3212, and the objective lens component 3214 is disposed on the incident side of the condenser component 3212. The objective lens component 3214 is disposed on the scanning lifting component 3211 and can be moved up and down by the scanning lifting component 3211 to achieve precise focusing. The condenser component 3212 is used to collect the illumination light emitted by the illumination component 323, amplify it, and transmit it to the acquisition camera 3213. The acquisition camera 3213 can acquire images during high-speed movement and, using algorithms, can classify and count red blood cells, white blood cells, and platelet cells. Thus, through the coordinated operation of the condenser component 3212, the acquisition camera 3213, and the objective lens component 3214, high-precision detection can be achieved, and high-quality image information can be obtained.

[0046] Optionally, such as Figure 6 As shown, in some embodiments, the objective lens assembly 3214 includes an objective lens converter 32141 disposed on the incident side of the condenser assembly 3212 and a plurality of objective lenses 32142 disposed on the objective lens converter 32141. Thus, the objective lens converter 32141 can simultaneously mount multiple objective lenses 32142 with different magnifications, enabling use in different scenarios and achieving scanning with different magnification combinations such as high magnification, low magnification, and high-low magnification switching.

[0047] Optionally, in some embodiments, the objective lens 32142 is a lens group composed of multiple lenses, which can overcome the imaging defects of a single lens and improve the optical quality of the objective lens 32142.

[0048] Optionally, such as Figure 7As shown, in some embodiments, the illumination assembly 323 includes an illumination source 3231, a focusing mirror 3232, a reflector 3233, a condenser lens 3234, and an aperture 3235. The illumination source 3231 emits illumination light. The focusing mirror 3232 is disposed on the light-emitting side of the illumination source 3231, the reflector 3233 is disposed on the emission side of the focusing mirror 3232, and the condenser lens 3234 is disposed on the reflection side of the reflector 3233. Thus, by utilizing the combination of multiple optical lenses, light loss from the illumination source 3231 can be reduced, allowing the illumination light to be projected onto the slide more efficiently, achieving 100X high-magnification rapid-flight scanning. The aperture 3235 is disposed between the condenser lens 3234 and the reflector 3233 to control the size of the illumination area.

[0049] Optionally, such as Figure 7 As shown, in some embodiments, the lighting assembly 323 further includes a heat dissipation assembly 3236, which is disposed on one side of the lighting source 3231. The heat dissipation assembly 3236 is used to dissipate heat from the lighting source 3231, reducing its temperature to prevent excessive heat generation.

[0050] Alternatively, in some embodiments, the heat dissipation component 3236 may be implemented as a cooling fan.

[0051] Optionally, such as Figure 6 As shown, in some embodiments, the panoramic recognition component 31 includes a panoramic camera 311, a panoramic illumination source 312, and a reflector 313. The panoramic camera 311 is positioned above the recognition location and is used to recognize the QR code on the glass slide and acquire images. The panoramic illumination source 312 is positioned to one side of the recognition location, and the reflector 313 is positioned below the recognition location. The panoramic illumination source 312 and the reflector 313 work together to illuminate the glass slide so that the panoramic camera 311 can recognize it.

[0052] Preferably, such as Figure 6 As shown, in some embodiments, the reflector 313 is inclined downwards and disposed on one side of the oil dripping assembly 322. In this way, the reflector 313 can form an oil recovery path and can collect most of the immersion varnish on its own. When the oil dripping assembly 322 drips immersion varnish, the excess immersion varnish can flow downwards along the reflector 313, thereby assisting in the recovery of immersion varnish and facilitating regular cleaning.

[0053] Optionally, such as Figure 8 and Figure 9As shown, in some embodiments, the feeding device 40 includes a feeding translation assembly 41 and a feeding assembly 42. The feeding assembly 42 includes a base 421, a power output element 422, a crank 423, a slider 424, a connecting rod 425, and a pusher rod 426. The base 421 is disposed on the feeding translation assembly 41. The power output element 422 is fixed to the base 421 and drivably connected to the crank 423. The crank 423 is rotatably connected to one end of the connecting rod 425. The other end of the connecting rod 425 is rotatably connected to the slider 424. The slider 424 is slidably disposed on the base 421. The pusher rod 426 is fixed to the slider 424. When the power output element 422 drives the crank 423 to rotate, the crank 423 drives one end of the connecting rod 425 to rotate, and the other end of the connecting rod 425 drives the slider 424 to slide up or down, thereby driving the pusher rod 426 to move up or down. When the unloading translation component 41 is driven and the unloading component 42 moves as a whole, the pusher rod 426 can push the glass slide to move from the clamping platform 131 into the unloading bin. In this way, the transmission mechanism based on the crank 423, connecting rod 425, and slider 424 can ensure the stability and low cost of the up-and-down movement of the pusher rod 426.

[0054] Optionally, in some embodiments, the pusher rod 426 includes a pusher rod 426 body and pusher protrusions on both sides of the pusher rod 426 body. The pusher rod 426 body is fixed to the slider 424. The pusher protrusions on both sides of the pusher rod 426 body can be used to push and pull the glass slide, thereby meeting the movement requirements of different positions in different scenarios.

[0055] Optionally, in some embodiments, the power output element 422 may be implemented as a servo motor in order to precisely control the rotation angle of the crank 423, thereby achieving precise control of the lifting and lowering motion of the push rod 426.

[0056] Optionally, in some embodiments, the unloading translation assembly 41 may include an unloading drive motor, a lead screw, and a lead screw nut. The lead screw nut is rotatably disposed on the lead screw, the unloading assembly 42 is disposed on the lead screw nut, and the unloading drive motor is drivably connected to the lead screw to drive the lead screw to rotate, thereby causing the lead screw nut to drive the unloading assembly 42 to move laterally.

[0057] Optionally, during the scanning process, some vibrations are unavoidable and can affect the slide scanning, such as when an external person touches the equipment casing, causing the entire machine to vibrate. Therefore, as Figure 1As shown, in some embodiments, the scanning device further includes a frame assembly 50, which includes an inner frame 51, an outer frame 52, and multiple anti-vibration pads 53. The inner frame 51 is disposed within the outer frame 52, and the anti-vibration pads 53 are disposed between the inner frame 51 and the outer frame 52. The loading bin, unloading bin, scanning transport device 10, loading clamping device 20, scanning detection device 30, and unloading device 40 are all disposed within the inner frame 51. In this way, through the isolation design of the inner frame 51 and the outer frame 52, the outer shell can provide strong rigid support, and the anti-vibration pads 53 can isolate the influence of external vibrations to avoid vertical movement that may occur during multi-band scanning, thereby avoiding the problem of poor image stitching.

[0058] Furthermore, in some embodiments, the scanning device also includes a slide transfer device 60, which is connected to the upper and lower storage bins to form a slide transport assembly line. Thus, by transferring the slides to be inspected and the inspected slides through the slide transfer device 60, automated line scanning can be achieved.

[0059] By way of example, referring to the scanning device of this application, this application provides the following slide scanning processes.

[0060] Example 1

[0061] like Figure 10 The flowchart shown illustrates a linear scanning detection process, which includes four steps: loading, identification, scanning, and unloading. In the loading step, the slide to be detected is located in the loading hopper. The loading lifting assembly 21 moves downwards, aligning the clamping assembly 23 with the slide in the loading hopper; the clamping assembly 23 clamps the slide from the loading hopper; the loading lifting assembly 21 moves upwards, causing the slide to leave the loading hopper; the rotating assembly 22 drives the clamping assembly 23 to perform one and two rotations, adjusting the slide to the pre-scanning state; the loading lifting assembly 21 moves downwards, bringing the slide to the loading position. In the identification step, the clamping assembly 13 holds the slide; the planar transport assembly 12 moves the clamping assembly 13 to the identification position; the panoramic identification assembly 31 identifies the slide's QR code and captures a panoramic image of the slide, determining the location to be scanned. In the scanning step, the planar transport assembly 12 moves the clamping assembly 13 to the scanning position; the oil-drip assembly 322 drips oil onto the slide; the scanning lifting assembly 3211 moves the objective lens 32142 up and down to achieve focusing; and the acquisition camera 3213 scans the slide. In the unloading step, the planar transport assembly 12 moves the clamping assembly 13 to the unloading position, and the unloading device 40 pushes the inspected slide into the unloading bin.

[0062] Example 2

[0063] like Figure 11The flowchart shown is for a reciprocating scanning detection process, which includes four steps: loading, identification, scanning, and unloading. In the loading step, the slide to be detected is located in the loading hopper. The loading lifting assembly 21 moves downwards, aligning the clamping assembly 23 with the slide in the loading hopper; the clamping assembly 23 clamps the slide from the loading hopper; the loading lifting assembly 21 moves upwards, causing the slide to leave the loading hopper; the rotating assembly 22 drives the clamping assembly 23 to perform one and two rotations, adjusting the slide to the pre-scanning state; the loading lifting assembly 21 moves downwards, bringing the slide to the loading position. In the identification step, the clamping assembly 13 clamps the slide; the planar transport assembly 12 moves the clamping assembly 13 to the identification position; the panoramic identification assembly 31 identifies the slide's QR code and captures a panoramic image of the slide, determining the location to be scanned. In the scanning step, the planar transport assembly 12 moves the clamping assembly 13 to the scanning position; the oil-drip assembly 322 drips oil onto the slide; the scanning lifting assembly 3211 moves the objective lens 32142 up and down to achieve focusing; and the acquisition camera 3213 scans the slide. In the unloading step, the planar transport assembly 12 moves the clamping assembly 13 to the loading position; the loading step is repeated in reverse so that the inspected slide is returned to the loading bin.

[0064] Example 3

[0065] like Figure 12 The diagram shows a flowchart of an emergency scanning detection process, which includes four steps: loading, identification, scanning, and unloading. In the loading step, the slide to be tested is located in the unloading hopper. The planar transport assembly 12 moves the clamping assembly 13 to the unloading position, and the unloading device 40 pushes the slide from the unloading hopper into the clamping assembly 13. In the identification step, the clamping assembly 13 holds the slide; the planar transport assembly 12 moves the clamping assembly 13 to the identification position; the panoramic identification assembly 31 identifies the slide's QR code and captures a panoramic image of the slide to determine the location to be scanned. In the scanning step, the planar transport assembly 12 moves the clamping assembly 13 to the scanning position; the oil-drip assembly 322 drips oil onto the slide; the scanning lifting assembly 3211 moves the objective lens 32142 up and down to achieve focusing; and the acquisition camera 3213 scans the slide. In the unloading step, the planar transport assembly 12 moves the clamping assembly 13 to the unloading position, and the unloading device 40 pushes the tested slide into the unloading hopper.
