The reagent card includes a first section and a second section with a smaller cross-sectional area relative to the first section. The card slot includes:

[0006] A first slot section, communicated with the opening, for accommodating the first section of the reagent card;

[0007] A second slot section, communicated with the first slot section, for accommodating the second section of the reagent card;

[0008] Wherein, the cross-sectional area of the first slot section is larger than that of the second slot section, and the size of the cross-sectional area of the first slot section is adapted to the size of the cross-sectional area of the first section of the reagent card, and the size of the cross-sectional area of the second slot section is adapted to the size of the cross-sectional area of the second section of the reagent card, so that when the second section of the reagent card is inserted into the card slot first, the reagent card cannot enter the second slot section.

[0009] The reagent card provided in the second aspect of the utility model includes a first section and a second section. When the reagent card is inserted into the card slot of the detection mechanism for detection, the first section of the reagent card is accommodated in the first slot section of the card slot, and the second section of the reagent card is accommodated in the second slot section of the card slot.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Such as Figure 1 and Figure 2As shown, an embodiment of the utility model proposes a detection device, which includes a detection mechanism 20 for detecting a reagent card 10, the detection mechanism 20 has an opening 21 and a card slot 22 connected to the opening 21, the reagent card 10 is inserted into the card slot 22 through the opening 21 for detection, and the reagent card 10 includes a first section 10a and a second section 10b having a smaller cross-sectional area relative to the first section 10a. The card slot 22 includes a first slot section 22a and a second slot section, the first slot section 22a is connected to the opening 21, and is used to accommodate the first section 10a of the reagent card 10, and the second slot section 22b is connected to the first slot section 22a, and is used to accommodate the second section 10b of the reagent card 10. Among them, the cross-sectional area of ​​the first groove section 22a is larger than the cross-sectional area of ​​the second groove section 22b, and the size of the cross-sectional area of ​​the first groove section 22a is adapted to the size of the cross-sectional area of ​​the first section 10a of the reagent card 10, and the size of the cross-sectional area of ​​the second groove section 22b is adapted to the size of the cross-sectional area of ​​the second section 10b of the reagent card 10, so that when the second section 10b of the reagent card 10 is inserted into the card slot 22 first, the reagent card 10 cannot enter the second groove section 22b.

[0029] The “cross-sectional area of ​​the first groove section 22a is adapted to the cross-sectional area of ​​the first section 10a of the reagent card 10” means that the cross-sectional area of ​​the first groove section 22a is slightly larger than the cross-sectional area of ​​the first section 10a of the reagent card 10, so that the first section 10a of the reagent card 10 can be smoothly embedded in the first groove section 22a, and the first section 10a of the reagent card 10 will not be displaced or shaken significantly in the first groove section 22a. For example, in one embodiment, the width of the cross section of the first groove section 22a is one millimeter larger than the width of the cross section of the first section 10a of the reagent card 10, and the height of the cross section of the first groove section 22a is one millimeter larger than the height of the cross section of the first section 10a of the reagent card 10.

[0030] Similarly, the "cross-sectional area of ​​the second groove section 22b is compatible with the cross-sectional area of ​​the second section 10b of the reagent card 10" means that the cross-sectional area of ​​the second groove section 22b is slightly larger than the cross-sectional area of ​​the second section 10b of the reagent card 10, so that the second section 10b of the reagent card 10 can be smoothly embedded in the second groove section 22b, and the second section 10b of the reagent card 10 will not be displaced or shaken significantly in the second groove section 22b. For example, in one embodiment, the width of the cross section of the second groove section 22b is one millimeter larger than the width of the cross section of the second section 10b of the reagent card 10, and the height of the cross section of the second groove section 22b is one millimeter larger than the height of the cross section of the second section 10b of the reagent card 10.

[0031] like Figure 3As shown, when the reagent card 10 is inserted into the card slot 22 in the correct way, the second section 10b of the reagent card 10 first enters the first slot section 22a of the card slot 22. As the operator pushes it forward, the second section 10b of the reagent card 10 enters the second slot section 22b of the card slot 22. When the first section 10a of the reagent card 10 runs to the second slot section 22b of the card slot 22, since the cross-sectional area of the second slot section 22b is smaller than that of the first slot section 22a, the first section 10a of the reagent card 10 cannot enter the second slot section 22b.

[0032] As Figure 4 shown, if the reagent card 10 is inserted into the card slot 22 in the reverse direction, that is, the first section 10a of the reagent card 10 first enters the first slot section 22a of the card slot 22. As the operator pushes it forward, when the first section 10a of the reagent card 10 runs to the second slot section 22b of the card slot 22, since the cross-sectional area of the second slot section 22b is smaller than that of the first slot section 22a, the first section 10a of the reagent card 10 cannot enter the second slot section 22b. At this time, the second section 10b of the reagent card 10 is exposed outside the card slot 22.

[0033] For the detection device proposed in the embodiment of the present utility model, by setting the card slot 22 of the detection mechanism 20 to include a first slot section 22a and a second slot section 22b, the cross-sectional area of the first slot section 22a is larger than that of the second slot section 22b, and the size of the cross-sectional area of the first slot section 22a is adapted to the size of the cross-sectional area of the first section 10a of the reagent card 10, and the size of the cross-sectional area of the second slot section 22b is adapted to the size of the cross-sectional area of the second section 10b of the reagent card 10. When the reagent card 10 is inserted in the reverse direction, the reagent card 10 cannot enter the second slot section 22b, and the user can promptly find that the reagent card 10 is inserted in the reverse direction and correct it in time, saving the detection time of the reagent card 10 and improving the detection efficiency.

[0034] As Figure 1 、 Figures 5 to 8 shown, in some embodiments, the card slot 22 includes a first slot wall 221, a second slot wall 222 and a third slot wall 223. The second slot wall 222 is connected to the first slot wall 221, and the third slot wall 223 is connected to the first slot wall 221 and is arranged opposite to the second slot wall 222. Among them, the second slot section 22b of the card slot 22 is provided with a limiting chamfer 224 at the connection between the second slot wall 222 and the first slot wall 221 and at the connection between the third slot wall 223 and the first slot wall 221. The limiting chamfer 224 is used to block the first section 10a of the reagent card 10 from entering the second slot section 22b of the card slot 22.

[0035] Understandably, since the second slot section 22b of the card slot 22 is provided with a limiting chamfer 224 at the connection between the second slot wall 222 and the first slot wall 221 and at the connection between the third slot wall 223 and the first slot wall 221, the cross-sectional area of the second slot section 22b is smaller than that of the first slot section 22a.

[0036] In one embodiment, the first slot wall 221 is the bottom wall of the card slot 22, and the second slot wall 222 and the third slot wall 223 are the two side walls of the card slot 22. The "bottom wall" is in terms of the normal use state of the detection device. Of course, the first slot wall 221 is not limited to being the bottom wall of the card slot 22. In some other embodiments, the first slot wall 221 can also be the top wall of the card slot 22. In some other embodiments, the first slot wall 221 can also be the side wall of the card slot 22. When the first slot wall 221 is the side wall of the card slot 22, the second slot wall 222 and the third slot wall 223 are the top wall and the bottom wall of the card slot 22.

[0037] In this embodiment, by setting the limiting chamfer 224, the cross-sectional area of the second slot section 22b is smaller than that of the first slot section 22a. The limiting chamfer 224 is convenient to process and can reduce the manufacturing cost.

[0038] Of course, the second slot section 22b of the card slot 22 is not limited to the above way of setting the limiting chamfer 224 to make the cross-sectional area of the second slot section 22b smaller than that of the first slot section 22a. For example, in some other embodiments, the cross-sectional area of the second slot section 22b can be made smaller than that of the first slot section 22a by setting the width of the second slot section 22b to be smaller than that of the first slot section 22a. Or by setting the height of the second slot section 22b to be smaller than that of the first slot section 22a, the cross-sectional area of the second slot section 22b can be made smaller than that of the first slot section 22a, which can be determined according to the actual design requirements.

[0039] In some embodiments, the length of the first slot section 22a is one-fifth to one-third of the total length of the card slot 22. Understandably, the shorter the first slot section 22a is set, when the reagent card 10 is inserted reversely, it can be found faster, so that it can be corrected in time and the detection time of the reagent card 10 can be saved.

[0040] As Figure 9 shown, in some embodiments, the slot wall of the card slot 22 is provided with a first positioning portion (not shown in the figure), and the first positioning portion is used to cooperate with the second positioning portion 11 provided on the reagent card 10 to position the reagent card 10 inserted into the card slot 22.

[0041] As Figure 9As shown, in some embodiments, the first positioning portion is a protrusion provided at the bottom of the card slot 22, and the second positioning portion 11 is a recess provided at the bottom of the reagent card 10. When the protrusion is embedded in the card slot 22, the positioning of the reagent card 10 is achieved. It should be noted that the positions of the protrusion and the card slot 22 can be interchanged, that is, the protrusion can be provided at the bottom of the reagent card 10, and the recess can be provided at the bottom of the card slot 22, which can be determined according to actual design requirements.

[0042] In some embodiments, the detection mechanism 20 further includes an optical component (not shown in the figure). The optical component is provided at the second slot section 22b and is used to read the two-dimensional code identifier E1 provided on the second section 10b of the reagent card 10. In this embodiment, by providing the optical component at the second slot section 22b of the card slot 22 and the two-dimensional code on the second section 10b of the reagent card 10, when the reagent card 10 is inserted in the reverse direction, the two-dimensional code cannot be recognized by the optical component.

[0043] In some embodiments, the detection mechanism 20 further includes a sensor component (not shown in the figure). The sensor component is used to generate detection information for identifying that the reagent card 10 is inserted in place when the reagent card 10 is inserted in place. In this embodiment, it is beneficial for the user to timely discover whether the reagent card 10 is inserted in the reverse direction. Optionally, the detection mechanism 20 further includes a prompting component. The detection information generated by the sensor component is used to give a prompt to the user through the prompting component. The prompting component can be but is not limited to a display screen, a buzzer, and an indicator light. The sensor component can be but is not limited to a micro switch.

[0044] As Figure 1 and Figure 2 As shown, an embodiment of the present invention further provides a reagent card 10. The provided reagent card 10 includes a first section 10a and a second section 10b. When the reagent card 10 is inserted into the card slot 22 of the detection mechanism 20 for detection, the first section 10a of the reagent card 10 is accommodated in the first slot section 22a of the card slot 22, and the second section 10b of the reagent card 10 is accommodated in the second slot section 22b of the card slot 22. The second slot section 22b has a smaller cross-sectional area than the first slot section 22a. Among them, the second section 10b of the reagent card 10 has a smaller cross-sectional area than the first section 10a of the reagent card 10, and the size of the cross-sectional area of the first slot section 22a is adapted to the size of the cross-sectional area of the first section 10a of the reagent card 10, and the size of the cross-sectional area of the second slot section 22b is adapted to the size of the cross-sectional area of the second section 10b of the reagent card 10, so that when the first section 10a of the reagent card 10 is inserted into the card slot 22 first, the reagent card 10 cannot enter the second slot section 22b.

[0045] The reagent card 10 proposed in the embodiment of the present utility model, by setting that the reagent card 10 includes a first section 10a and a second section 10b, the second section 10b of the reagent card 10 has a smaller cross-sectional area than the first section 10a of the reagent card 10, and the cross-sectional area of the first groove section 22a is adapted to the cross-sectional area of the first section 10a of the reagent card 10, and the cross-sectional area of the second groove section 22b is adapted to the cross-sectional area of the second section 10b of the reagent card 10. When the reagent card 10 is inserted reversely, the reagent card 10 cannot enter the second groove section 22b, and the user can promptly find that the reagent card 10 is inserted reversely and correct it in time, saving the detection time of the reagent card 10 and improving the detection efficiency.

[0046] As Figure 2 , Figures 9 to 12 shown, in some embodiments, the reagent card 10 includes a first surface 13, a second surface 14, and a third surface 15. The second surface 14 is connected to the first surface 13, and the third surface 15 is connected to the first surface 13 and is disposed opposite to the second surface 14. Among them, chamfers 16 are provided at the joints of the second surface 14 and the first surface 13 and the joints of the third surface 15 and the first surface 13 of the second section 10b of the reagent card 10, so that the cross-sectional area of the second section 10b of the reagent card 10 is smaller than the cross-sectional area of the first section 10a of the reagent card 10.

[0047] In one embodiment, the first surface 13 is the bottom surface of the reagent card 10, and the second bottom surface and the third bottom surface are the two side surfaces of the reagent card 10. The so-called "bottom surface" refers to the reagent card 10 in the normal use state. Of course, the first bottom surface is not limited to being the bottom surface of the reagent card 10. In some other embodiments, the first bottom surface may also be the top surface of the reagent card 10. In some other embodiments, the first bottom surface may also be the side surface of the reagent card 10. When the first bottom surface is the side surface of the reagent card 10, the second bottom surface and the third bottom surface are the top surface and the bottom surface of the reagent card 10.

[0048] In this embodiment, by setting the chamfers 16, the cross-sectional area of the second section 10b of the reagent card 10 is made smaller than the cross-sectional area of the first section 10a of the reagent card 10. The chamfers 16 are convenient to process and can reduce the manufacturing cost.

[0049] Of course, the second section 10b of the reagent card 10 is not limited to the above-described method of chamfering 16 to achieve a cross-sectional area of the second section 10b smaller than that of the first section 10a. For example, in some other embodiments, the cross-sectional area of the second section 10b of the reagent card 10 can be made smaller than that of the first section 10a by setting the width of the second section 10b of the reagent card 10 to be smaller than the width of the first section 10a of the reagent card 10. Or by setting the thickness of the second section 10b of the reagent card 10 to be smaller than the thickness of the first section 10a of the reagent card 10, so that the cross-sectional area of the second section 10b of the reagent card 10 is smaller than that of the first section 10a of the reagent card 10, which can be determined according to actual design requirements.

[0050] In some embodiments, the length of the first section 10a of the reagent card 10 is one-fifth to one-third of the total length of the reagent card 10.

[0051] As Figure 2 shown, in some embodiments, the reagent card 10 further includes a fourth surface 17, which is connected to the second surface 14 and the third surface 15 and is disposed opposite to the first surface 13. A sample addition area M1 and a viewing window area M2 are provided on the fourth surface 17 of the reagent card 10. A first anti-slip structure 18 is provided at the first section 10a of the reagent card 10 and on the fourth surface 17. In this embodiment, by providing the first anti-slip structure 18, the friction of the fourth surface 17 of the reagent card 10 can be increased, so that the operator can firmly hold the reagent card 10 and avoid the situation where the reagent card 10 drops due to unstable holding.

[0052] As Figure 2 shown, in some embodiments, the first anti-slip structure 18 includes anti-slip bumps forming a decorative pattern on the fourth surface 17. In this embodiment, the first anti-slip structure 18 can not only play an anti-slip role but also play a decorative role. In some embodiments, the first anti-slip structure 18 is designed as a decorative pattern of animal claws. Of course, it is not limited to being designed as a decorative pattern of animal claws, and it can also be other patterns, for example, a decorative pattern of an animal image, or a pattern of a flower, etc., which can be determined according to actual design requirements.

[0053] It should be noted that the first anti-slip structure 18 is not limited to being provided as bumps. For example, in some other embodiments, the first anti-slip structure 18 can also be provided as stripe protrusions, or as a soft rubber with a large friction force, which can be determined according to actual design requirements.

[0054] As Figure 2As shown, in some embodiments, a second anti-slip structure 19 is provided at the first section 10a of the reagent card 10 and at the second surface 14 and the third surface 15. In some usage scenarios, an operator may need to pick up the reagent card 10 from both sides. In this embodiment, by providing the second anti-slip structure 19, the friction on both sides of the reagent card 10 can be increased, enabling the operator to firmly hold the reagent card 10 from both sides and preventing the reagent card 10 from dropping due to unstable grasping.

[0055] As Figure 2 shown, in some embodiments, the second anti-slip structure 19 includes a plurality of ridges spaced along the length direction of the reagent card 10 and extending along the thickness direction of the reagent card 10. It should be noted that the second anti-slip structure 19 is not limited to being configured as ridges. For example, in some other embodiments, the anti-slip structure can also be configured as protrusions, or as a soft rubber with a large friction force, which can be determined according to actual design requirements.

[0056] As Figure 2 shown, in some embodiments, an identification area M3 is provided on the fourth surface 17 of the reagent card 10, and the identification area M3 is provided with at least one of an arrow indication identification E2, a project name identification E3, and a two-dimensional code identification E1, wherein the arrow indication identification E2 is used to identify the insertion direction when the reagent card 10 is inserted into the detection mechanism 20.

[0057] In some embodiments, the arrow indication identification E2, the project name identification E3, and the two-dimensional code identification E1 can be formed on the fourth surface 17 of the reagent card 10 by means of laser engraving, silk screening, or sticking labels.

[0058] As Figure 2 shown, in some embodiments, a recessed handwritten area M4 is provided on the fourth surface 17 of the reagent card 10. By providing the handwritten area M4, it is convenient for users to temporarily write additional sample information. And by recessing the handwritten area M4, the text inside the handwritten area M4 is not easily scratched by the detection mechanism 20 when the reagent card 10 is inserted into the detection mechanism 20.

[0059] As Figure 2 shown, in some embodiments, the identification area M3, the window area M2, the handwritten area M4, and the sample addition area M1 are sequentially arranged from the second section 10b to the first section 10a of the reagent card 10.

[0060] As Figure 2As shown, in some embodiments, an arrow indication mark E2, an item name mark E3, and a two-dimensional code mark E1 are provided on the surface of the reagent card 10. The arrow indication mark E2, the item name mark E3, the two-dimensional code mark E1, the window area M2, the handwriting area M4, and the sample addition area M1 are sequentially arranged from the second section 10b to the first section 10a of the reagent card 10.

[0061] In some embodiments, a positioning groove or a positioning protrusion is provided on the first surface 13 of the reagent card 10. The positioning groove or the positioning protrusion is used to cooperate with the positioning protrusion or the positioning groove provided on the detection mechanism 20, so that the reagent card 10 can be stably held in the card slot 22 of the detection mechanism 20.

[0062] As Figure 2 shown, in some embodiments, the length of the area where the first anti-slip structure 18 is provided on the reagent card 10 is greater than or equal to 20 mm. In this embodiment, the length of the area where the first anti-slip structure 18 is provided is long enough to facilitate the user to pick up the reagent card 10.

[0063] As Figure 2 shown, in some embodiments, the length of the area where the second anti-slip structure 19 is provided on the reagent card 10 is greater than or equal to 20 mm. In this embodiment, the length of the area where the second anti-slip structure 19 is provided is long enough to facilitate the user to pick up the reagent card 10.

[0064] As Figure 13 and Figure 14 shown, in some embodiments, a card ejection slot F is provided in the first section 10a of the reagent card 10. The card ejection slot F is used to assist in manually ejecting the reagent card 10 from the card slot 22 of the detection mechanism 20. When the reagent card 10 is inserted into the card slot 22 in place, the card ejection slot F is exposed outside the detection device 100.

[0065] The existing detection device 100 is provided with a card ejection mechanism. After the reagent card 10 completes the detection, the card ejection mechanism automatically ejects the reagent card 10 from the detection device 100. Once the card ejection mechanism fails or the power is cut off during the detection process, automatic card ejection cannot be achieved. In addition, after the reagent card 10 is automatically ejected by the existing detection device 100, the exposed length of the reagent card 10 is short, for example, 10 mm to 15 mm, which is not convenient for the operator to manually pick up the card. In this embodiment, by providing a card ejection slot F on the reagent card 10, when the card ejection mechanism fails or the power is cut off during the detection process and automatic card ejection cannot be achieved, or when the exposed length of the reagent card 10 is short and it is not convenient for the operator to manually pick up the card, the operator can insert a tool, for example, the tip of a gel pen or the front end of a pair of tweezers, into the card ejection slot F to pull out the reagent card 10 from the detection device 100, so that the operator can conveniently remove the reagent card 10 from the detection device 100.

[0066] It should be noted that the provision of the card ejection slot F is not limited to the first section 10a of the reagent card 10 to facilitate the user to remove the reagent card 10 from the card slot 22 of the detection device 100. For example, in some other embodiments, a card ejection protrusion may be provided on the first section 10a of the reagent card 10. When the operator needs to eject the reagent card 10 from the detection device 100, the operator can use a tool, such as the tip of a gel pen or the front end of forceps, to press against the side of the card ejection protrusion facing the detection device 100 and dial out the reagent card 10 from the detection device 100.

[0067] As Figure 14 shown, in some embodiments, the first section 10a of the reagent card 10 includes a connection end G1 and a free end G2 opposite to the connection end G1. The connection end G1 is connected to the second section 10b. The distance from the card ejection slot F or the card ejection protrusion to the free end G2 on the side facing the connection end G1 is L, and L = 4 mm to 5 mm. It can be understood that when the reagent card 10 is inserted into the card slot 22, the free end G2 is the exposed end. By setting the card ejection slot F or the card ejection protrusion as close as possible to the free end G2, when the card ejection slot F or the card ejection protrusion can be fully exposed, the exposed amount of the reagent card 10 can be reduced, and the space occupied by the detection device 100 can be reduced. Optionally, in one embodiment, the distance from the card ejection slot F or the card ejection protrusion to the free end G2 on the side facing the card slot 22 is 4.5 mm.

[0068] As Figure 14 shown, in some embodiments, the card ejection slot F or the card ejection protrusion is provided on the first surface 13 of the reagent card 10. As can be seen from the above, the first surface 13 is the bottom surface of the reagent card 10 in the normal use state. By setting the card ejection slot F or the card ejection protrusion on the bottom surface of the reagent card 10, when the reagent card 10 is inserted into the detection device 100, the card ejection slot F or the card ejection protrusion can be hidden. Of course, it is also possible to set the card ejection slot F or the card ejection protrusion on other surfaces of the reagent card 10, which can be determined according to actual design needs.

[0069] As Figure 14 shown, in some embodiments, the width of the card ejection slot F in the first direction is W, and W = 3.5 mm ± 1 mm. The first direction is the length direction of the reagent card 10. In this embodiment, by setting the width of the card ejection slot F to this value, the width is adapted to the sizes of the tips of common gel pens or forceps in laboratories and medical institutions. That is, the operator does not need to use special tools to perform manual card ejection, which improves the convenience of operation. Optionally, in one embodiment, the width of the card ejection slot F in the first direction is 3.5 mm.

[0070] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
