Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical detection instruments, in particular to a reagent card incubation device and an immunochromatographic analyzer. BACKGROUND

[0002] Immunochromatographic analysis is a unique immunological analysis method that appeared in the early 1980s. It often uses a strip-shaped fiber chromatographic material as a solid phase. Through capillary action, the sample solution moves on the chromatographic strip, and at the same time, the analyte in the sample reacts with the receptors (such as antibodies or antigens) on the chromatographic material to form an immune complex. The immune complex is enriched or intercepted in a certain area (detection zone) of the chromatographic material during the chromatographic process. Through enzyme reaction or direct use of visual markers (such as colloidal gold), an intuitive experimental phenomenon (such as color development) is obtained. The free marker is separated from the bound marker automatically. This analysis technology is simple, fast, and easy to judge, so it is very suitable for use in diagnosis, health care, physical examination, etc. by hospitals at all levels, families or individuals.

[0003] The prior art automatic multi-channel immunochromatographic analyzer can complete the incubation and testing of multiple samples and multiple items at the same time. Specifically, it includes an incubation device, a droplet device, and a detection device arranged on the incubation device. The incubation device is provided with a plurality of installation slots for reagent cards. The installation slots are used to set the reagent cards. During the rotation of the incubation device, the droplet device drips liquid for the reagent cards, and the detection device is used to detect the reagent cards after the liquid is dripped and incubated for a preset time. After the detection is completed, a special card unloading assembly is needed to push the reagent cards out, so that the structure of the incubation device is complex, occupies a large space, and a card pushing time needs to be reserved to detect the next reagent card, which reduces the detection efficiency of the chromatographic analyzer and the throughput of the immunochromatographic analyzer.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] This application provides a reagent card incubation device 10, such as... Figure 1 and Figure 2As shown, the reagent card incubation device 10 includes a base 11, an incubation tray 12 arranged on the base 11, a driving assembly 13, and a card moving assembly 14 connected with the driving assembly 13. The incubation tray 12 is provided with a plurality of slots 121 along the radial direction of the incubation tray 12. The driving assembly 13 drives the card moving assembly 14 to transfer the reagent card between the plurality of slots 121 and unload the reagent card at one of the slots 121.

[0031] The reagent card incubation device 10 provided by the embodiment of the present application is applied to an immunochromatographic analyzer. The reagent card storage area of the immunochromatographic analyzer pushes the reagent card into the reagent card incubation device 10. The reagent card is dripped in the reagent card incubation device 10. After the reaction solution is dripped on the reagent card, the reaction solution reacts with the antigen-antibody on the reagent card in the constant-temperature incubation environment. Then, the reagent card after the reaction is detected. According to the working principle of the reagent card incubation device 10, the slots 121 in the embodiment of the present application can be divided into a temporary storage slot 122, a dripping slot 123, an incubation slot 125, and a detection slot 124. The temporary storage slot 122 is used to store the reagent card pushed by the reagent card storage area. The dripping slot 123 is used to place the reagent card that needs to be dripped. The incubation slot 125 is used to place the reagent card that is incubated after the dripping is completed. The detection slot 124 is used to detect the reagent card after the incubation is completed. Since the reaction solution reacts with the antigen-antibody on the reagent card (that is, incubation) needs a certain time, the incubation slot 125 can be provided with a plurality of slots.

[0032] When the reagent card incubation device 10 provided by the embodiment of the present application works, the temporary storage slot 122 receives the reagent card from the reagent card storage area. The driving assembly 13 drives the card moving assembly 14 to move to the temporary storage slot 122. The card moving assembly 14 takes the reagent card in the temporary storage slot 122 and moves to the dripping slot 123 under the driving of the driving assembly 13. After the dripping is completed, the above steps are repeated to transfer the reagent card to the incubation slot 125. After the incubation is completed, the above steps are repeated to transfer the reagent card to the detection slot 124. After the detection is completed, the card moving assembly 14 unloads the reagent card in the detection slot 124. The card moving assembly 14 in the embodiment of the present application can not only transfer the reagent card but also unload the reagent card after the detection is completed. In this way, the structure of the reagent card incubation device 10 can be simplified. The reagent card is pushed while being transferred, thereby improving the throughput of the immunochromatographic analyzer. It should be noted that the throughput refers to the number of reagent card detections completed in a certain fixed time, which corresponds to the detection efficiency of the reagent card incubation device 10.

[0033] It should be noted that since the incubation needs a certain time, after the first reagent card is transferred to the incubation slot 125, the next reagent card can be dripped and transferred to the incubation slot 125, and so on until the incubation slot 125 is full of reagent cards for incubation. After the first reagent card is incubated, the first reagent card is detected and unloaded.

[0034] The reagent card incubation device 10 provided by the application comprises a base 11, an incubation disc 12 arranged on the base 11, a driving assembly 13, and a card moving assembly 14 connected with the driving assembly 13. The incubation disc 12 is provided with a plurality of slot positions 121 along the radial direction of the incubation disc 12. The driving assembly 13 drives the card moving assembly 14 to transfer the reagent card between the plurality of slot positions 121 and unload the reagent card at one of the slot positions 121. The driving assembly 13 drives the card moving assembly 14 to transfer the reagent card between the slot positions 121, complete the dripping, incubation, detection and unloading of the reagent card. Since the card moving assembly 14 of the embodiment of the application can achieve the unloading of the reagent card after the transfer of the reagent card, the structure of the reagent card incubation device 10 can be simplified, and the pushing of the reagent card can be achieved while the reagent card is being transferred, thereby improving the throughput of the immune chromatography analyzer.

[0035] Optionally, as shown in Figure 2 and Figure 5 The card moving assembly 14 comprises a rotating disc 142 coaxial with the incubation disc 12 and sleeved with the incubation disc 12, and a rotating shaft 141 connected with the rotating disc 142. The rotating shaft 141 is connected with the driving assembly 13 to drive the rotating disc 142 to rotate under the driving of the driving assembly 13. The rotating disc 142 is provided with pre-storage card positions 143 along the radial direction of the rotating disc 142. The driving assembly 13 is fixedly arranged on the rotating disc 142. When the pre-storage card positions 143 and the slot positions 121 are in the same extension direction, the driving assembly 13 drives the reagent card to transfer between the pre-storage card positions 143 and the slot positions 121.

[0036] The card moving assembly 14 comprises a rotating disc 142 coaxial with the incubation disc 12 and sleeved with the incubation disc 12, so that the rotating disc 142 is arranged in the same plane with the incubation disc 12, thereby making the pre-storage card positions 143 and the slot positions 121 located at the same height. The rotating shaft 141 is connected with the driving assembly 13, so that the driving assembly 13 drives the rotating shaft 141 to rotate and drives the rotating disc 142 to rotate. During the rotation of the rotating disc 142, when the pre-storage card positions 143 and the slot positions 121 are in the same extension direction, the driving assembly 13 drives the reagent card to transfer between the pre-storage card positions 143 and the slot positions 121.

[0037] Specifically, the driving assembly 13 drives the rotating shaft 141 to rotate, and drives the rotating disc 142 to rotate, so that the pre-stored card position 143 is in the same extension direction as the temporary storage position 122, the driving member 144 drives the reagent card to be transferred from the temporary storage position 122 to the pre-stored card position 143, and then the rotating disc 142 rotates under the driving of the driving assembly 13, so that the pre-stored card position 143 is in the same extension direction as the drop position 123, the driving member 144 drives the reagent card to be transferred from the pre-stored card position 143 to the drop position 123, to complete the transfer from the temporary storage position 122 to the drop position 123. Similarly, the transfer from the drop position 123 to the incubation position 125 is completed, and the transfer from the incubation position 125 to the detection position 124 is completed.

[0038] In order to simplify the structure of the reagent card incubation device 10, as shown in Figure 2 、 Figure 3 , the incubation disc 12 is arranged in a ring shape, and the rotating disc 142 is arranged in the ring-shaped enclosed area.

[0039] In an implementable manner of the embodiment, the driving member 144 is further configured to push the reagent card in the fixed slot position 121 out of the other end of the fixed slot position 121 to achieve card unloading when the driving member 144 transfers one reagent card to one fixed slot position 121.

[0040] The fixed slot position 121 refers to a certain slot position 121. In order to improve the detection throughput of the reagent card incubation device 10, the card is directly unloaded from the detection position 124 after the detection is completed, that is, the fixed slot position 121 is the detection position 124. After the detection of the first reagent card is completed, the first reagent card is placed in the detection position 124. When the second reagent card is transferred to the detection position 124 after the second reagent card is incubated, the front end of the second reagent card abuts against the rear end of the first reagent card. During the transfer of the second reagent card, the first reagent card gradually exits the detection position 124 from the other end of the detection position 124, thereby achieving the unloading of the first reagent card. The embodiment adopts the second reagent card to push the first reagent card to achieve the unloading of the first reagent card, which can reduce the card unloading assembly in the prior art, thereby reducing the components of the reagent card incubation device 10, simplifying the structure of the reagent card incubation device 10, and simultaneously, without reserving unloading time, thereby reducing the detection time of the reagent card and improving the throughput of the immunochromatographic analyzer.

[0041] Optionally, as shown in Figure 2 , the slot position 121 is arranged on one side of the incubation disc 12 close to the base 11, the card moving assembly 14 is arranged in the interior of the base 11, and the driving assembly 13 is arranged on the side of the incubation disc 12 away from the base 11.

[0042] In practical application, the base 11 is usually arranged on the frame of the immunochromatographic analyzer, so that the side of the incubation tray 12 provided with the slot positions 121 faces downward, and the card moving assembly 14 is arranged inside the base 11 to realize the function of transferring the reagent cards. Since the space inside the base 11 is limited, the driving assembly 13 is arranged on the other side of the incubation tray 12 to realize effective utilization of the space and reduce the space occupied by the reagent card incubation device 10.

[0043] As known from the above, the side of the incubation tray 12 provided with the slot positions 121 faces downward, so as to avoid the reagent cards from falling under the action of gravity. In addition, the two sides of the side of the slot positions 121 close to the base 11 can be protruded to the center to form limiting portions, and the sliding channel between the two limiting portions is used to move the reagent cards by the card moving assembly 14. The limiting portions limit the vertical direction of the reagent cards.

[0044] In an implementable manner of the embodiment of the present application, as shown in Figure 5 The driving member 144 drives the reagent cards through the pushing member 145 arranged on the rotating disc 142. The pushing member 145 is provided with pushing rods 146 extending into the pre-storage card positions 143 at both ends in the extension direction of the pre-storage card positions 143. The pushing member 145 is driven to drive the pushing rods 146 at both ends to push the reagent cards to enter the pre-storage card positions 143 from one slot position 121 or to enter another slot position 121 from the pre-storage card positions 143.

[0045] Specifically, when the extension directions of the pre-storage card positions 143 and the temporary storage positions 122 are the same, at this time, the pushing rod 146 of the pushing member 145 away from the center of the disc abuts against the outer side wall of the reagent card in the temporary storage position 122. The driving member 144 drives the pushing member 145 to move from the temporary storage position 122 to the pre-storage position, so that the pushing rod 146 drives the reagent card to move into the pre-storage card position 143 when moving inward, so that the reagent card is transferred from the temporary storage position 122 to the pre-storage card position 143. At this time, the pushing member 145 returns to the starting position, and then the rotating disc 142 rotates under the driving of the driving assembly 13, so that the extension direction of the pre-storage card position 143 is the same as that of the drop position 123. At this time, the pushing rod 146 of the pushing member 145 close to the center of the disc abuts against the inner side wall of the reagent card in the temporary storage position 122. The driving member 144 drives the pushing member 145 to move outward again, so that the pushing rod 146 drives the reagent card to move into the drop position 123 when moving outward, so that the reagent card is transferred from the pre-storage card position 143 to the drop position 123 to complete the transfer from the temporary storage position 122 to the drop position 123. Similarly, the transfer from the drop position 123 to the incubation position 125 is completed, and the transfer from the incubation position 125 to the detection position 124 is completed.

[0046] Since the reagent card incubation time is relatively long, after the reagent card is transferred from the drop position 123 to the incubation position 125, the driving member 144 drives the pushing member 145 to move along the circumferential direction of the incubation tray to return to the zero position, and then other reagent cards are transferred.

[0047] Optionally, as shown in Figure 5 The first photoelectric detector is arranged on the rotating disc 142 and faces the pusher 145, and is used to sense the position of the pusher 145 relative to the rotating disc 142. The second photoelectric detector is arranged in the pre-storage card position 143 and is used to sense the state of the pre-storage card position 143.

[0048] The first photoelectric detector is used to sense the position of the pusher 145 relative to the rotating disc 142. As described above, the pusher 145 is used to transfer the reagent card from the pre-storage card position 143 to the slot position 121, or to transfer the reagent card from the slot position 121 to the pre-storage card position 143, so that the pusher 145 has two positions relative to the rotating disc 142, one is a start position close to the rotating disc 142, and the other is an end position far from the rotating disc 142. The first photoelectric detector is used to sense whether the pusher 145 is located at the start position or the end position, so that the state of the pusher 145 can be determined in real time, and the working efficiency of the pusher 145 is improved. In order to detect the two states of the pusher 145, the first photoelectric detector includes two photoelectric detectors, which are used to detect the start position and the end position respectively, and thus the position state of the pusher 145 can be accurately determined.

[0049] The second photoelectric detector is arranged in the pre-storage card position 143 and is used to sense whether the pre-storage card position 143 contains a reagent card, so as to determine the state of the pre-storage card position 143 in real time.

[0050] The moving card assembly 14 includes a plurality of elements, and the plurality of elements need to be electrically connected and / or signal connected with the outside. In order to form a wiring channel, the inside of the rotating shaft can be hollow, and the power lines and / or signal lines of the plurality of elements can pass through the hollow of the rotating shaft to realize electrical connection and / or signal connection. In addition, in order to prolong the service life of the moving card assembly 14, all the signal lines and power lines are made of high-torque-resistant cables to prevent the service life of the cables from being too short due to repeated rotation of the moving card assembly 14.

[0051] In an implementable manner of the embodiment of the present application, as shown in Figure 1 , Figure 6 The driving assembly 13 includes an encoder motor, the rotating shaft of the encoder motor is connected with the rotating shaft 141 through a synchronous pulley, and a bearing seat 15 is arranged on the side of the incubation disc 12 away from the base 11. The rotating shaft 141 passes through the bearing seat 15 and is connected with the synchronous pulley.

[0052] When the driving assembly 13 includes an encoder motor, the position of the rotating disc 142 can be positioned without repeated zero-finding, thereby reducing the time for transferring the reagent card, further improving the detection efficiency of the reagent card, and improving the detection throughput of the reagent card incubation device 10.

[0053] The encoder motor is misaligned with the rotating disc 142 by the synchronous wheel, and a frame is arranged on the incubation disc 12 to fix the encoder motor. In addition, a fixing plate is arranged to fix the rotating disc 142, and the fixing plate is connected with the rotating disc 142 and the incubation disc 12 simultaneously. A bearing seat 15 is arranged on the fixing plate to support the synchronous belt wheel.

[0054] Optionally, as shown in Figure 4 The slot 121 includes a plurality of temporary storage positions 122, a droplet position 123, a detection position 124 and a plurality of incubation positions 125. The droplet position 123 and the incubation position 125 are provided with a blocking part 16 at an end away from the center of the incubation disc 12.

[0055] Since the droplet position 123 and the detection position 124 are used for dropping liquid and detection respectively, the operation time is short, while the incubation position 125 is used for incubation, which needs a long time. Therefore, the slot 121 is arranged as a plurality of temporary storage positions 122, a droplet position 123, a detection position 124 and a plurality of incubation positions 125.

[0056] Since the temporary storage position 122 and the detection position 124 need to be inserted from one end of the slot 121 and removed from the other end of the slot 121, the slot 121 of the temporary storage position 122 and the detection position 124 is a through slot. The droplet position 123 and the incubation position 125 need to be inserted from one end and removed from the same end. Therefore, in order to avoid the reagent card from sliding out of the droplet position 123 and the incubation position 125, the droplet position 123 and the incubation position 125 are provided with a blocking part 16 at an end away from the center of the incubation disc 12.

[0057] The number of the temporary storage position 122 and the incubation position 125 is not limited in the embodiment, and can be set according to the actual incubation condition and the incubation time. Since the temporary storage position 122 and the incubation position 125 are both used for placing the reagent card, the incubation position 125 can be used for incubation when the incubation position 125 is not enough in actual use.

[0058] In addition, in order to further limit the droplet position 123 and the incubation position 125, the width of the slot 121 of the droplet position 123 and the incubation position 125 can be set to be small, as long as the reagent card can be inserted smoothly. In this way, on the one hand, the reagent card can be prevented from sliding out, and on the other hand, the position of the reagent card can be accurately limited. Since the droplet position 123 needs to drop the reagent card into the reaction liquid, accurate positioning of the reagent card can ensure the consistency of the sample dropping position. Similarly, the detection position 124 needs to scan and detect the reagent card, and accurate positioning of the reagent card can ensure the detection accuracy.

[0059] In an implementable manner of the embodiment, as shown inFigure 2 , Figure 7 As shown, the base 11 includes a shell, which is connected to the incubation tray 12 to form a constant temperature chamber. The reagent card incubation device 10 also includes a temperature control component, which includes a controller, a temperature sensor 19 disposed at the slot 121, and a heating component 18 disposed in the constant temperature chamber. The controller controls the heating component 18 according to the temperature information of the temperature sensor 19 so that the slot 121 is within a preset temperature range.

[0060] A constant temperature is beneficial for the incubation of reagent cards. The temperature control components and controller keep the temperature in the constant temperature chamber within a preset range, providing a good temperature environment for the incubation of reagent cards.

[0061] The number of temperature sensors 19 is not limited in this embodiment. One sensor can be set in one incubation position 125, or one sensor can be set in each incubation position 125. Alternatively, temperature sensors 19 can be set in the dropper position 123, the incubation position 125, and the detection position 124. Considering that the number of temperature sensors 19 will increase the cost and control difficulty, this embodiment of the application sets four temperature sensors 19 evenly on the incubation tray 12.

[0062] Optional, such as Figure 7 As shown, the heating assembly 18 includes a heating element 181 and a heat-conducting plate 182 between the heating element 181 and the card transfer assembly 14. The heat-conducting plate 182 is made of a high thermal conductivity material.

[0063] The heat-conducting plate 182 can evenly distribute the heat generated by the heating plate, resulting in a uniform temperature within the constant temperature chamber and preventing large temperature differences that could lead to uncontrollable incubation time. Furthermore, the heat-conducting plate 182, made of a highly thermally conductive material, can rapidly transfer heat, ensuring that the temperature within the constant temperature chamber quickly reaches the preset range after startup.

[0064] In one possible implementation of the embodiments of this application, such as Figure 7 As shown, the heating element 181 is a semiconductor heating element, and the cooling surface of the semiconductor heating element is also connected to a heat dissipation component 183, which passes through the outer casing and communicates with the outside.

[0065] The heat dissipation component 183 can quickly dissipate the cold air from the cooling surface of the semiconductor heating element, thereby improving the heating speed of the heating surface of the semiconductor heating element and reaching the preset temperature in a short time.
