[0030] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0031] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.
[0032] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly.

[0033] In order to solve the technical problem in the related art that the reagent card 11 cannot be accurately placed in the detection position, resulting in inaccurate detection results, the present application provides a reagent card detection device that can detect and adjust the position of the reagent card holder 10 and the reagent card 11, ensure that the reagent card 11 is in the detection position, and improve the reliability of the detection results.
[0034] The present application embodiment provides a reagent card detection device, such as Figure 1 As shown, the reagent card detection device mainly includes a base 1, a first drive mechanism, a second drive mechanism, a reagent card holder 10 and an imaging module 2; the first drive mechanism and the second drive mechanism both adopt linear motion mechanisms and can perform reciprocating linear motion along a preset direction. Among them, the first drive mechanism is fixed to the base 1, and the second drive mechanism is installed on the first drive mechanism. The first drive mechanism is used to drive the second drive mechanism to reciprocate along the first direction; the reagent card holder 10 is installed on the second drive mechanism and can reciprocate along the second direction under the drive of the second drive mechanism. The reagent card holder 10 is provided with a first card slot, and the reagent card 11 can be installed and fixed to the reagent card holder 10 through the first card slot; the imaging module 2 is fixed at a preset height above the base 1 and is used to capture images of the reagent card holder 10 and the reagent card 11.
[0035] When testing the reagent card 11, the reagent card 11 to be tested is first installed in the reagent cartridge 10 through the first card slot; the first drive mechanism drives the second drive mechanism to move relative to the base 1 in a first direction to adjust the position of the reagent cartridge 10 and the reagent card 11 in the first direction; the second drive mechanism drives the reagent cartridge 10 and the reagent card 11 to move in a second direction to adjust the position of the reagent cartridge 10 and the reagent card 11 in the second direction. Because the first direction and the second direction are arranged at an angle, the first drive mechanism and the second drive mechanism drive the reagent cartridge 10 and the reagent card 11 to move at any point in the preset area, so as to move the reagent cartridge 10 and the reagent card 11 to the testing position.
[0036] The imaging module 2 can capture images of the reagent cartridge 10 and the reagent card 11 so as to detect the positions of the reagent cartridge 10 and the reagent card 11 based on the images, thereby ensuring that the first drive mechanism and the second drive mechanism adjust the reagent cartridge 10 and the reagent card 11 to corresponding detection positions, thereby improving the accuracy of the detection of the reagent card 11.
[0037] In addition, the reagent card detection device also includes a control module, which is used to identify and locate the reagent card holder 10 and the reagent card 11 based on the image information. It should be noted that the control module's identification and positioning based on the image belongs to the prior art, and the present application does not improve on this part; the improvement of the present application is that an imaging module 2 is provided on the base 1 to obtain an image of the reagent card holder 10 and the reagent card 11, and the imaging module 2 transmits the image to the control module for processing, and identifies and locates the reagent card holder 10 and the reagent card 11, so that the positions of the reagent card holder 10 and the reagent card 11 are adjusted by the first drive mechanism and the second drive mechanism, so that the two are moved to the detection position more accurately, thereby improving the accuracy of the detection of the reagent card 11.
[0038] The above images include not only the position detection images of the reagent cartridge 10 and the reagent card 11, but also typically include an image of the identification code of the reagent card 11 and an image of the color-developed area of the reagent card 11. The control module can identify the model, type, and sample information of the reagent card 11 based on the identification code image of the reagent card 11; and can also analyze the color-developed image of the display area to obtain a test result. The control module's identification of the reagent card 11 and obtaining a test result based on the identification code image and the display area image are both prior art and are not described in detail in this application.
[0039] In some embodiments, the first drive mechanism comprises a combination of a first drive motor 3, a first screw 4, and a drive base plate 5. The drive base plate 5 is slidably connected to the base 1 and can slide back and forth relative to the base 1 in a first direction. The second drive mechanism is mounted on the drive base plate 5, so that the first drive mechanism can drive the second drive mechanism to reciprocate in the first direction via the drive base plate 5.
[0040] To improve the accuracy of the reciprocating sliding of the drive base plate 5 in the first direction, a first guide rail 6 is provided on the base 1. A first guide groove adapted to fit the first guide rail 6 is provided at the bottom of the drive base plate 5. At least two sets of first guide rails 6 and first guide grooves may be provided. The first drive motor 3 is mounted and fixed to one end of the base 1 in the first direction. The output shaft of the first drive motor 3 is connected to the first end of the first screw rod 4. The drive base plate 5 defines a through hole for the first screw rod 4 to pass through. The screw nut of the first screw rod 4 is fixedly connected to the drive base plate 5, and can, for example, be embedded and fixed in the through hole of the drive base plate 5.
[0041] When the first drive motor 3 rotates, it drives the first screw rod 4 to rotate. Due to the restrictions of the drive base plate 5 and the first guide rail 6, the screw nut of the first screw rod 4 does not rotate accordingly, but moves in the first direction relative to the first screw rod 4, thereby driving the drive base plate 5 to move in the first direction, thereby driving the second drive mechanism, the reagent cartridge holder 10 and the reagent card 11 to move in the first direction, and adjusting the position of the reagent cartridge holder 10 and the reagent card 11.
[0042] Similarly, the second driving mechanism can adopt the structure of the second driving motor 7, the second screw rod 8 and the driving slide 9 combination.The second driving motor 7 is fixed on the driving base plate 5, and the driving slide 9 is slidably connected to the driving base plate 5, and can relatively drive the base plate 5 to slide back and forth along the second direction.Reagent cassette holder 10 is then installed on the driving slide 9, can reciprocate along the second direction under the drive of the driving slide 9. Exemplary, the bottom of the reagent cassette holder 10 can be offered the second draw-in groove, and the reagent cassette holder 10 is fixed on the driving slide 9 by the second draw-in groove card, thereby conveniently changing different types of reagent cassette holders 10 quickly as required, completing the detection of the reagent card 11 of different models.
[0043] To improve the accuracy of the reciprocating sliding of the drive slider 9 relative to the drive base plate 5 in the second direction, a slide groove adapted to fit the drive slider 9 can be provided on the upper end surface of the drive base plate 5, the slide groove extending in the second direction. A first end of the second screw rod 8 is connected to the output shaft of the second drive motor 7, and the drive slider 9 defines a through hole for the second screw rod 8 to pass through. The drive slider 9 and the second screw rod 8 are fixedly connected by a screw nut. For example, the screw nut of the second screw rod 8 can be embedded and fixed in the through hole of the drive slider 9.
[0044] When the second drive motor 7 rotates, it drives the second screw rod 8 to rotate. Due to the limitations of the drive slider 9 and the chute, the screw nut of the second screw rod 8 does not rotate accordingly. Instead, it moves relative to the second screw rod 8 in the second direction, thereby driving the drive slider 9 to move in the second direction, thereby driving the reagent cartridge 10 and the reagent card 11 to move in the first direction, thereby adjusting the position of the reagent cartridge 10 and the reagent card 11. In particular, the first direction and the second direction are perpendicular to each other, that is, the extension directions of the first screw rod 4 and the second screw rod 8 are perpendicular to each other.
[0045] Whether the reagent card 11 is in the detection position is closely related to not only the position of the reagent cartridge 10, but also whether the reagent card 11 is properly installed relative to the reagent cartridge 10. In order to ensure that the reagent card 11 is properly installed relative to the reagent cartridge 10, the reagent card detection device provided in the embodiment of the present application further includes a mechanical positioning assembly in the first card slot of the reagent cartridge 10 that cooperates with the reagent card 11. The mechanical positioning assembly is used to position the reagent card 11 so that the reagent card 11 is installed in the appropriate position in the first card slot by the mechanical positioning assembly.
[0046] Combined with reference Figure 1 and Figure 2 , a positioning groove 111 is provided on the side of the reagent card 11, and the mechanical positioning component can adopt an elastic positioning bead 12. The elastic positioning bead 12 includes a sleeve shell, a positioning bead that can be slidably retracted and partially protrudes from the sleeve shell, and a spring compressed and arranged in the sleeve shell. Driven by the spring elastic force, the positioning bead can maintain a state of partially protruding from the sleeve shell. When squeezed, the positioning bead can compress the spring and slide back into the sleeve shell. When the reagent card 11 is slidably loaded into the first slot, the positioning bead is squeezed and retracted into the sleeve shell; when the reagent card 11 slides to the elastic positioning bead 12 corresponding to the positioning groove 111, driven by the spring elastic force, the positioning bead can move to a state of partially protruding from the sleeve shell, and the part protruding from the sleeve shell enters the positioning groove 111 of the reagent card 11, positioning the reagent card 11, ensuring that the reagent card 11 is installed in place relative to the reagent cartridge 10, and then ensuring that the reagent card 11 can accurately move to the detection position along with the reagent cartridge 10, thereby improving the detection accuracy.
[0047] Specifically, the first card slot includes a slot bottom surface, slot side surfaces connected to both sides of the slot bottom surface, and a slot retaining edge connected to one end of the slot side surface away from the slot bottom surface. The slot retaining edge forms a slot with a width smaller than the width of the reagent card 11, thereby limiting the reagent card 11. The elastic positioning beads 12 or the mechanical positioning component can be set on the slot side surface of the first card slot, and can be set on the slot side surface on a single side of the first card slot, or can be set relatively on two groups of slot side surfaces of the first card slot. The positioning groove 111 on the reagent card 11 is set corresponding to the elastic positioning beads 12 in the first card slot. By setting the mechanical positioning component on the slot side surface of the first card slot, the imaging module 2 of the reagent card 11 is not affected while positioning the reagent card 11, and the detection result is not affected.
[0048] In a preferred embodiment provided herein, the imaging module 2 uses a camera including a zoom component, so that the imaging module 2 can obtain, at different focal lengths, a position detection image of the reagent cartridge 10 and the reagent card 11, an identification code image of the reagent card 11, and an image of the color-developed area of the reagent card 11. For example, the imaging module 2 can obtain a position detection image of the reagent cartridge 10 and the reagent card 11 at a first focal length by zooming with the help of the zoom component, and can obtain an image of the color-developed area of the reagent card 11 at a second focal length by zooming with the help of the zoom component.
[0049] A fill light component (not shown in the drawings) is also installed on the base 1. The fill light component can use multiple groups of LED lamp beads. The fill light component is arranged facing the movement area of the reagent cartridge 10, that is, the position adjustment area. It can fill light for the reagent cartridge 10 and the reagent card 11 in the detection position as needed, thereby improving the imaging quality of the imaging module 2, and thereby improving the position detection accuracy of the reagent cartridge 10 and the reagent card 11 and the reliability of the detection results of the reagent card 11.
[0050] The reagent card detection device provided in the embodiment of the present application also connects the first drive mechanism, the second drive mechanism and the imaging module 2 to the control module, so that the control module can identify and locate the reagent cartridge 10 and the reagent card 11 according to the image obtained by the imaging module 2, and then control the first drive mechanism and the second drive mechanism to adjust the position of the reagent cartridge 10 according to the deviation between the identification and positioning structure and the set position, thereby ensuring that the reagent cartridge 10 and the reagent card 11 are automatically and accurately moved to the detection position, thereby improving the reliability of the detection results.
[0051] It should be noted that whether the control module performs image recognition and positioning based on the image obtained by the imaging module 2, or the control module controls the movement of the corresponding driving mechanism based on the positioning result, both belong to the existing technology, and this application will not elaborate on this part in detail.
