Description

Technical Field

[0001] The present invention relates to the technical field of chemiluminescence detection, and in particular to a chemiluminescence analyzer, a sample reagent loading scanning system and a scanning method thereof. Background Art

[0002] In a chemiluminescence analysis instrument, reagents need to be distinguished by identification codes, such as reagent types and batch numbers, and samples need to be distinguished by identification codes for patient identities. The current identification code scanning method uses two identification code scanners to scan the reagent identification code and the sample identification code respectively. Usually, an identification code scanner is used to scan the sample identification code. When scanning the sample identification code, the sample rack needs to be transported to the sample identification code scanning area by a transport mechanism for identification code scanning. After the identification code scanning is completed, the sample transport mechanism is used to transport the sample rack back to its original position. An identification code scanner is used to scan the reagent identification code, and the reagent tray can be rotated to transport the reagent kits at various positions in the reagent tray to the position of the reagent identification code scanner. However, the chemiluminescence analysis instrument uses two identification code scanners to scan the identification codes of samples and reagents, which will incur higher costs and take up more space, making the overall size of the chemiluminescence analyzer large.

[0067] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the chemiluminescence analyzer, sample reagent loading scanning system and scanning method of the present invention are further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0068] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the mechanism or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0069] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0070] See also Figures 1 to 4 The present invention provides a sample reagent loading and scanning system, which is applied to a chemiluminescent analyzer to provide samples and reagents for chemiluminescent analysis, ensuring that the chemiluminescent analyzer can perform detection continuously; moreover, the sample reagent loading and scanning system can also identify the position and type of samples and reagents, so that the chemiluminescent analyzer knows the position of the sample and reagent to be absorbed and the items that the corresponding samples should be detected. Specifically, the sample reagent loading system is used to carry a plurality of sample containers 5 and a plurality of reagent containers. The sample container 5 is used to carry the sample to be tested. It should be noted that the specific type of the sample to be tested is not limited. In some embodiments, the sample to be tested includes a solid sample or a liquid sample. It can be understood that when testing a liquid sample, it is necessary to carry the liquid sample in a container such as a test tube and place it on a sample rack before it can be carried out. Further liquid samples include but are not limited to blood samples. The reagent container is used to carry various reagents required for sample testing.

[0071] Since there are differences between each sample and there are differences in the tests to be performed, the sample reagent loading scanning system can also be used to identify the location of the sample and the test items, and to identify the location and type of the reagent. Specifically, identification codes are set on the outside of the sample container 5 and the outside of the reagent container. The sample reagent loading scanning system can scan the identification codes of each sample container 5 to identify the location of the sample and the items to be tested; the sample reagent loading scanning system can also scan the identification codes of each reagent container to identify the location and type of the reagent. This can avoid problems such as performing the wrong test items or adding sample reagents incorrectly, and ensure that the sample test is carried out smoothly. It is understandable that the identification code can be a barcode, a QR code or other types of information that are easy to identify.

[0072] In the present invention, the sample reagent loading and scanning system comprises a sample loading mechanism 1, a reagent loading mechanism 2 and an identification code scanner 3. The sample loading mechanism 1 is used to load a plurality of sample containers 5, and the reagent loading mechanism 2 is used for a plurality of loading reagent containers. The sample loading mechanism 1 is sleeved on the outside of the reagent loading mechanism 2, and the sample loading mechanism 1 and the reagent loading mechanism 2 rotate independently of each other. In this way, when loading the same number of sample containers 5, less space is required on the left and right or front and back to reduce the volume of the sample reagent loading mechanism 2, which is conducive to reducing the volume of the whole machine. In the present embodiment, the reagent loading mechanism 2 is arranged in a disc shape, and accordingly, the shape of the sample loading mechanism 1 is annular, and the sample loading mechanism 1 and the reagent loading mechanism 2 are arranged concentrically, so that the sample reagent loading and scanning system occupies the least space, and at the same time, the sample loading mechanism 1 and the reagent loading mechanism 2 do not contact, ensuring that the movement between the two will not interfere, and ensuring smooth operation.

[0073] Moreover, the sample loading mechanism 1 has a sample suction station, and the dispensing needle of the chemiluminescence analyzer sucks the sample in the sample container 5 at the sample suction station, and the reagent loading mechanism 2 has a reagent suction station, and the dispensing needle sucks the reagent in the reagent container at the reagent suction station. It can be understood that the sample suction station and the reagent suction station are fixed positions on the chemiluminescence analyzer. When the dispensing needle needs to suck a sample, the sample loading mechanism 1 drives the sample container 5 thereon to rotate, so that the sample container 5 of the sample to be detected is at the sample suction station, and then the sample is transferred by the dispensing needle; when the dispensing needle sucks the reagent, the reagent loading mechanism 2 drives the reagent container thereon to rotate, so that the reagent container of the reagent to be sucked is at the reagent suction station, and then the reagent is transferred by the dispensing needle.

[0074] The identification code scanner 3 is used to scan the identification code. The chemiluminescence analyzer has a main control device, which is electrically connected to the identification code scanner 3. The main control device is used to control the identification code scanner 3 to perform scanning operations and store various information scanned and obtained by the identification code scanner 3, such as information such as the location of the sample and the items to be detected, such as information such as the location and type of the reagent. Before the chemiluminescence analyzer detects the sample, the identification code scanner 3 first scans the identification code of each sample container 5 in the sample loading mechanism 1, and scans the identification code of each reagent container in the reagent loading mechanism 2. It can be understood that there is no order in which the identification code scanner 3 scans the sample identification code and the reagent identification code. The sample identification code can be scanned first, or the reagent identification code can be identified first, which has no substantial effect on the detection of the sample. Of course, in other embodiments of the present invention, the identification code of the sample container 5 and the identification code of the reagent container can also be scanned during the sample detection process.

[0075] The identification code scanner 3 is located on the outside of the sample reagent loading mechanism 2. The annular sample loading mechanism 1 divides the space into an inner and outer side, the inner side refers to the space where the reagent loading mechanism 2 is located, and correspondingly, the other space is the outer side of the sample loading mechanism 1. The identification code scanner 3 can directly scan the sample identification code on the sample loading mechanism 1, but the sample reagent loading mechanism 2 is sleeved on the outer side of the reagent loading mechanism 2, and the sample loading mechanism 1 will block the reagent loading mechanism 2, which is not conducive to scanning the reagent container identification code. Therefore, a scanning notch 14 is provided on the sample loading mechanism 1. The scanning notch 14 is to facilitate the identification code scanner 3 to scan the identification code of the reagent container in the reagent loading mechanism 2 on the inner side of the sample loading mechanism 1 through the scanning notch 14. Specifically, the identification code scanner 3 can scan the identification code of the sample container 5 on the sample loading mechanism 1, and the identification code scanner 3 can also scan the identification code of the reagent container on the reagent loading mechanism 2 through the scanning notch 14.

[0076] The identification code scanner 3 is electrically connected to the main control device, and transmits basic information of the sample such as location, information of the item to be detected, and basic information of the user to the main control device. Moreover, during the processing of the sample, the main control device tracks the sample detected in real time. After the sample is subjected to luminescence detection, the main control device obtains the sample parameters detected in the incubation photometry step, and matches the sample parameters with the basic information of the sample, so that the sample and its detection parameters correspond one to one to avoid errors. In this embodiment, the sample container 5 is loaded manually. When loading, the identification code of the sample container 5 is placed outward to facilitate scanning by the identification code scanner 3. Of course, when the sample container 5 is automatically loaded and transported, if the identification code of the sample container 5 is not facing outward, a rotating structure can also be provided to rotate the sample container 5 so that the identification code of the sample container 5 faces outward.

[0077] The sample reagent loading and scanning system of the present invention adopts a sample loading mechanism 1 which is sleeved on the outer side structure of the reagent loading mechanism 2, and cooperates with the identification code scanner 3. When the sample loading mechanism 1 drives the sample container 5 therein to rotate, the identification code scanner 3 scans the identification code of the sample container 5. When the scanning notch 14 of the sample loading mechanism 1 corresponds to the identification code scanner 3, the reagent loading mechanism 2 drives the reagent container therein to rotate, and the identification code scanner 3 scans the identification code of the reagent container through the scanning notch 14, that is, the identification code of the sample container 5 and the identification code of the reagent container are scanned by the same identification code scanner 3, which effectively solves the problems of high cost and large occupied space caused by scanning by two identification code scanners 3, thereby reducing production costs and reducing occupied space, so that the size of the sample reagent loading and scanning system is small, thereby reducing the overall size of the chemiluminescence analyzer.

[0078] Preferably, the identification code scanner 3 is fixedly arranged on the outside of the sample loading mechanism 1. This makes it convenient for the chemiluminescence analyzer to determine the position information of each sample container 5 and each reagent container. The sample loading mechanism 1 drives the sample container 5 to rotate to the identification code scanner 3 in turn for scanning; the scanning notch 14 corresponds to the identification code scanner 3, and the reagent loading mechanism 2 drives the reagent container to rotate to the scanning notch 14 in turn for scanning. Specifically, after the identification code scanner 3 is fixed, the identification code scanner 3 has a scanning area, and the scanning area can be projected onto the sample loading mechanism 1 and the reagent loading mechanism 2. When scanning the identification code of the sample container 5, the sample loading mechanism 1 drives each sample container 5 thereon to rotate, so that the sample container 5 passes through the scanning area of ​​the identification code scanner 3 in turn, so that the identification code scanner 3 records the information of the sample container 5 in turn, and realizes the scanning of the identification code of the sample container 5. When scanning the reagent container identification code, first align the scanning notch 14 of the sample loading mechanism 1 with the identification code scanner 3, so that the identification code scanner 3 can pass through the notch corresponding to the reagent container in the reagent loading mechanism 2, and then the reagent loading mechanism 2 drives each reagent container thereon to rotate, so that the reagent containers pass through the scanning area of ​​the identification code scanner 3 in sequence, so that the identification code scanner 3 records the information of the sample container 5 in sequence, and realizes the scanning of the reagent container identification code. Of course, in other embodiments of the present invention, the identification code scanner 3 can also be non-fixed, as long as the identification code scanner 3 can be aligned with the scanning notch 14, the scanning of the reagent container identification code can be realized.

[0079] As an implementable embodiment, the sample loading mechanism 1 includes a plurality of sample racks 11 arranged in an arc shape, a sample storage drive structure 13 and an annular chassis 12. The sample rack 11 is used to carry a sample container 5 having a sample. The plurality of sample racks 11 are sequentially mounted on the annular chassis 12. The scanning notch 14 is disposed between two adjacent sample racks 11. The sample storage drive structure 13 drives the annular chassis 12 to rotate and drives the sample rack 11 to rotate. Each arc-shaped sample rack 11 can store a plurality of sample containers 5 having a sample. Moreover, the arc radius of each sample rack 11 is consistent, ensuring that the plurality of sample racks 11 form an annular structure after assembly. For example, the sample rack 11 includes an upper support and a plurality of support columns. The plurality of support columns support the upper support. The upper support has a plurality of receiving holes, and the sample container 5 is installed in the receiving holes. Moreover, the plurality of support columns are arranged at intervals, and the plurality of support columns can be directly mounted on the annular chassis 12. Of course, the sample rack 11 can also include a lower bracket, which is arranged on the annular chassis 12, and the bottom of the support column is mounted on the lower bracket. It is understandable that the sample racks 11 can be overlapped and connected, or connected by structures such as connectors; and can be fixed by means of buckles, connectors, etc. In this embodiment, the number of sample racks 11 is five.

[0080] The scanning gap 14 is arranged between two adjacent sample racks 11, that is, there is a preset spacing between the two adjacent sample racks 11 to form the scanning gap 14. It can be understood that after the two adjacent sample racks 11 are overlapped, there is a large space between the adjacent sample racks 11, through which the identification code of the reagent container in the reagent loading mechanism 2 can be scanned. Of course, the adjacent sample racks 11 can be supported separately by support columns, and the scanning gap 14 can also be ensured to exist between the adjacent sample racks 11. Preferably, in this embodiment, the number of the scanning gap 14 is one, that is, one of the scanning gaps 14 identifies the identification code of the reagent container, so that the scanning requirements can be met, and at the same time, the structure of the sample rack 11 can be made compact, and as many sample containers 5 as possible can be carried to avoid frequent replenishment of the sample containers 5. Of course, in other embodiments of the present invention, the scanning gap 14 can be set between any two adjacent sample racks 11, or the scanning gap 14 can be set between several two adjacent sample racks 11, so that the scanning requirements can also be met.

[0081] For example, the sample storage drive structure 13 includes a sample storage drive motor and a gear transmission structure. The annular chassis 12 has a tooth portion. The gear transmission structure transmits and connects the sample storage drive motor and the annular chassis 12. The sample storage drive motor drives the synchronous belt structure to drive the annular chassis 12 to rotate. Of course, the gear transmission structure can also be replaced by a chain transmission structure, a synchronous belt structure, etc. The sample storage drive structure 13 drives the annular chassis 12 to drive the sample rack 11 thereon to rotate, so that the sample container 5 to be tested rotates to the sample suction station, and the sample is sucked by the dispensing needle. After the dispensing needle sucks the sample, the sample storage drive structure 13 can drive the annular chassis 12 to drive the sample rack 11 to rotate again, so that the next sample container 5 to be tested rotates to the sample suction station.

[0082] Optionally, the sample reagent loading and scanning system also includes a storage fixing plate, which is arranged on the bearing platform of the chemiluminescence analyzer and is used to install various components of the sample loading mechanism 1 and the reagent loading mechanism 2 to facilitate the rotation drive of the sample loading mechanism 1 and the reagent loading mechanism 2 to avoid interference. The sample storage driving structure 13 is arranged on the storage fixing plate, and the annular chassis 12 is rotatably fixed on the storage fixing plate. The sample storage driving structure 13 drives the annular chassis 12 to drive the sample rack 11 and the sample container 5 thereon to rotate relative to the storage fixing plate. In addition, the identification code scanner 3 is located on the outside of the sample loading mechanism 1 and is fixed on the storage fixing plate.

[0083] Optionally, the sample loading mechanism 1 also includes a pulley bearing, the pulley bearing has a slideway, the sliding bearing is placed flat on the storage fixing plate, and the edge of the annular chassis 12 is located in the slideway of the pulley bearing. When the sample storage driving structure 13 drives the annular chassis 12 to rotate, the pulley bearing can support the annular chassis 12 so that the annular chassis 12 rotates smoothly. At the same time, the slideway can also guide the annular chassis 12 to rotate. For example, the number of pulley bearings is multiple, and the multiple pulley bearings are evenly distributed on the circumference of the annular chassis 12 to ensure that the annular chassis 12 is evenly stressed and reliably supported. In this embodiment, the number of pulley bearings is four.

[0084] Optionally, the sample reagent loading scanning system also includes a needle cleaning structure 15 for cleaning the dispensing needle, and the needle cleaning structure 15 is arranged on the annular chassis 12 and is located between two adjacent sample racks 11. That is to say, the needle cleaning structure 15 is integrated on the sample loading mechanism 1, rather than being arranged on other structures of the chemiluminescence analyzer, so that the overall size of the chemiluminescence analyzer can be reduced. In addition, the needle cleaning structure 15 is arranged on the sample loading mechanism 1, which can also reduce the movement path of the dispensing needle and improve the sample processing efficiency. This is because the dispensing needle needs to be cleaned after transferring the sample or reagent to avoid cross contamination when transferring the sample or reagent next time. After the dispensing needle transfers the sample or reagent, it returns to the sample loading mechanism 1 to be cleaned directly, reducing the path of the dispensing needle moving to other positions for cleaning and then returning to the sample loading mechanism 1 or the reagent loading mechanism 2, improving the transfer efficiency of the dispensing needle, and then improving the efficiency of the whole machine. Moreover, the needle cleaning structure 15 can be a cleaning pool, the bottom of which is connected to the liquid pipeline, and the cleaning liquid is transported and the cleaning waste liquid is discharged through the liquid pipeline. Of course, the needle cleaning structure 15 can also be other structures capable of carrying cleaning liquid, such as a bottle, etc. Moreover, the needle cleaning structure 15 can also transport enhanced cleaning liquid through the liquid pipeline to perform enhanced cleaning on the dispensing needle to ensure the cleaning effect.

[0085] Optionally, the sample loading mechanism also includes a plurality of metal springs, which are respectively arranged on a plurality of sample racks 11, and the plurality of metal springs are in contact with the outer wall of the sample container 5, and the metal springs are also connected to the ground, so as to increase the capacitance value of the sample in the sample container 5. The metal springs can tightly clamp the sample container 5 on the sample rack 11, so that the sample container 5 is reliably fixed on the sample rack 11, and the sample container 5 is prevented from moving when the sample loading mechanism 1 rotates. Moreover, the metal springs are also connected to the ground, so that the metal springs can transfer the static electricity in the sample container 5 to the ground, eliminate the static electricity, and increase the capacitance value of the sample in the sample container 5. In this way, when the dispensing needle absorbs the sample, even if there is very little sample in the sample container 5, the dispensing needle can accurately absorb the sample.

[0086] It is understandable that the metal springs can correspond to the sample containers 5 one by one, that is, each sample container 5 corresponds to a metal spring; or partial metal springs can be provided, and the sample containers 5 with fewer samples can be placed on the metal springs.

[0087] See also Figures 9 to 11As an implementable embodiment, the sample reagent loading and scanning system further includes a limit detection mechanism 4, which is arranged corresponding to the sample loading mechanism 1. The sample loading mechanism 1 has a limit height. The limit detection mechanism 4 is installed at the limit height to detect whether the sample container 5 in the loading mechanism is loaded in place. Here, installation in place refers to whether the bottom of the sample rack 11 is installed on the sample rack 11, and whether the top of the sample container 5 exceeds the maximum distance allowed by the sample rack 11. The limit height of the sample loading mechanism 1 means that after the sample container 5 is installed on the sample rack 11, the height at which the top of the sample container 5 is located can meet the rotation requirements of the sample rack 11, and there will be no scratching. It can be understood that the limit height is the position of the sample rack 11 used to measure the top of the sample container 5. If the bottom of the sample container 5 is not in place, the top of the sample container 5 will exceed the limit height. Since the sample rack 11 of the sample loading mechanism 1 rotates during operation, the part of the top of the sample container 5 that exceeds the limit height will scratch the lower area above the chemiluminescence analyzer, causing sample leakage and causing biosafety risks. Therefore, the limit detection mechanism 4 is used to detect whether the sample container 5 is installed in place. If it is installed in place, the sample loading mechanism 1 can drive the sample container 5 to rotate, making it convenient for the dispensing needle to absorb the sample; if it is not installed in place, the sample loading mechanism 1 cannot drive the sample container 5 to rotate, and the user is required to install the sample container 5 on the sample rack 11, or replace the sample container 5.

[0088] Specifically, the limit detection mechanism 4 includes a detection structure, which includes a receiver 42 and a transmitter 41 arranged in pairs. The receiver 42 and the transmitter 41 are respectively arranged on the inner and outer sides of the sample loading mechanism 1 and are located above the sample loading mechanism 1. The receiver 42 receives the signal emitted by the transmitter 41, and the sample container 5 is loaded in place. It can be understood that if the top of the sample container 5 exceeds the maximum height allowed by the sample rack 11, at this time, there is a sample container 5 between the receiver 42 and the transmitter 41, and the signal emitted by the transmitter 41 will be reflected by the sample container 5. The receiver 42 cannot receive the signal, indicating that the sample container 5 is not installed in place and the sample container 5 will not be allowed to move; if the sample container 5 is installed in place, the top of the sample container 5 is located above the limit height. At this time, there is no sample container 5 blocking the receiver 42 and the transmitter 41, and the signal emitted by the transmitter 41 can be received by the receiver 42, indicating that the sample container 5 is installed in place and the sample container 5 is allowed to move. For example, the receiver 42 and the transmitter 41 are opposite optical couplers, the transmitter 41 is a transmitting tube, and the receiver 42 is a receiving tube, and the optical signal is used to detect whether the sample container 5 is installed in place. Of course, in other embodiments of the present invention, the transmitter 41 and the receiver 42 can also be other structures that can transmit and receive signals.

[0089] Furthermore, the position limit detection mechanism 4 includes two detection structures, which are arranged at intervals along the circumference of the sample detection structure, and the space between the two detection structures is used to take and place the sample container 5. In other words, the sample loading mechanism 1 has a take-and-place area, and the two detection structures are respectively located at the edges of the take-and-place area, so that when the sample loading mechanism 1 drives the sample container 5 to rotate clockwise or counterclockwise, the detection structure can detect whether the sample container 5 is loaded in place, thereby improving the reliability of the operation of the sample loading mechanism 1 and ensuring the performance of the chemiluminescence analyzer.

[0090] After the sample reagent loading and scanning system of the present invention adopts the limit detection mechanism 4, it can avoid the biosafety risk caused by the abnormal installation or size of the sample container 5 causing the top of the sample container 5 to collide with the chemiluminescence analyzer. After cooperating with the annular sample rack 11, the running trajectory of the sample container 5 in the chemiluminescence analyzer is a circle, the relative movement area is small, and the probability of collision is further reduced, thereby ensuring the safe operation of the chemiluminescence analyzer.

[0091] See also Figures 1 to 4 As an implementable embodiment, the reagent loading mechanism 2 includes a reagent pot 21, a reagent tray 22 and a reagent storage drive structure 23. The reagent tray 22 is accommodated in the reagent pot 21. The reagent tray 22 is used to load multiple reagent containers. The reagent storage drive structure 23 drives the reagent tray 22 to rotate relative to the sample loading mechanism 1. The reagent pot 21 can play a refrigeration function, which can refrigerate the reagents on the reagent tray 22 to achieve low-temperature storage of the reagents; moreover, when the whole machine is in the off state, the reagent pot 21 can support the reagents to continue to cool to a lower temperature so that the reagents can stay in the machine overnight.

[0092] The reagent storage drive structure 23 includes a reagent storage drive motor, a synchronous belt structure and a rotating shaft. The rotating shaft extends into the reagent pot 21. The synchronous belt structure drives the reagent storage drive motor and the rotating shaft, and the reagent tray 22 is installed on the rotating shaft. The reagent storage drive motor drives the rotating shaft to rotate through the synchronous belt structure, and then the rotating shaft drives the reagent tray 22 to rotate, so that the reagent container to be absorbed in the reagent tray 22 is transferred to the reagent absorbing station. After the dispensing needle absorbs the reagent, the reagent storage drive structure 23 can drive the reagent tray 22 to rotate again, so that the next reagent container to be detected is rotated to the reagent absorbing station. Of course, the synchronous belt structure can be replaced by a gear transmission structure, a chain transmission structure, etc.

[0093] Preferably, the axis of the annular chassis 12, the axis of the reagent disk 22 and the axis of the reagent pot 21 coincide. This can make the structure of the sample loading mechanism 1 and the reagent loading mechanism 2 compact, minimize the volume of the sample reagent loading scanning system, and reduce the overall volume of the chemiluminescence analyzer; moreover, the annular chassis 12 and the reagent disk 22 rotate around the axis of the reagent pot 21, which can ensure smooth movement, avoid eccentric movement, and avoid interference.

[0094] The identification code scanner 3 scans the identification code of the reagent container through the reagent pot 21 after scanning the notch 14. That is to say, the sample container 5 is located in the reagent pot 21, and after the sample loading mechanism 1 drives the scanning notch 14 to correspond to the identification code scanner 3, the identification code scanner 3 can scan the identification code of the reagent container in the reagent pot 21 through the scanning notch 14. It is understandable that the reagent pot 21 can be made of a transparent material, so that the identification code scanner 3 can directly scan the identification code of the reagent container through the transparent reagent pot 21; or the reagent container can be exposed to the top of the reagent pot 21, so that the identification code of the reagent container is exposed, which is convenient for the identification code scanner 3 to scan.

[0095] Optionally, the reagent storage drive structure 23 also includes a rotating bearing, which is arranged on the reagent pot 21, and the outer ring of the rotating bearing is connected to the reagent pot 21, and the inner ring of the rotating bearing is connected to the rotating shaft, and the reagent storage drive motor drives the rotating shaft to rotate through the synchronous belt structure, so that the rotating shaft drives the center of the reagent pot 21 at the position of the reagent disk 22 to rotate. The rotating shaft is fixed to the reagent pot 21 through the rotating bearing, and the rotating bearing can also avoid interference between the rotating shaft and the stationary reagent pot 21, ensuring smooth and reliable rotation.

[0096] In this embodiment, the reagent pot 21 has a scanning window 211. That is, the identification code scanner 3 scans the identification code of the reagent container in the reagent pot 21 through the scanning window 211. In this way, the loss of cold can be avoided, and it is easy to maintain the low temperature environment in the reagent pot 21. When scanning the identification code of the reagent container, the scanning window 211, the scanning notch 14, and the identification code scanner 3 correspond to each other, and the reagent tray 22 drives the multiple reagent containers to rotate, and drives the reagent containers to move to the scanning window 211 in sequence, and the identification code scanner 3 scans the identification code of the reagent container.

[0097] It should be noted that, since there is a gap between adjacent sample containers 5, in order to prevent the identification code scanner 3 from scanning the reagent container identification code in the reagent pot 21 through the gap, before scanning the identification code of the sample container 5, the reagent disk 22 is first controlled to rotate so that the space between adjacent reagent containers corresponds to the scanning window 211. In this way, when scanning the identification code of the sample container 5, the identification code scanner 3 is always aligned with the scanning window 211 of the reagent pot 21 and the space between two adjacent reagent containers. When the sample loading mechanism 1 drives the sample container 5 to rotate, the sample container 5 is scanned by the identification code scanner 3 in turn. Even if the gap between adjacent sample containers 5 is aligned with the identification code scanner 3, since the scanning window 211 corresponds to the space between two reagent containers, the identification code scanner 3 will not mistakenly scan the identification code of the reagent container, thereby ensuring the accuracy of the scanning result. Optionally, the spacing between adjacent sample containers 5 is minimized as much as possible, so that the spacing cannot completely scan the identification code of the reagent container, and at the same time, the capacity of the sample container 5 can be increased as much as possible.

[0098] See also Figures 1 to 6 , further, the reagent pot 21 has a transparent window 26, which is installed at the scanning window 211. The transparent window 26 corresponds to the identification code scanner 3. During the rotation of the sample rack 11, the identification code scanner 3 scans the identification code of the reagent container in the reagent tray 22 through the lens window by a preset spacing. Preferably, the reagent pot 21 is fixedly arranged so that the transparent window 26 and the identification code scanner 3 remain stationary. The transparent window 26 can isolate the inside and outside of the reagent pot 21 to avoid the loss of cold in the reagent pot 21. The identification code of the reagent container on the reagent tray 22 in the transparent window 26 corresponding reagent pot 21, like this, the identification code scanner 3 scans the identification code of the reagent container on the reagent tray 22 by a preset gap and the transparent window 26. Optionally, the transparent window 26 can be transparent glass, or it can be made of other transparent materials.

[0099] As an implementable embodiment, the reagent loading mechanism 2 also includes a refrigeration structure 24, which is used to refrigerate the reagent pot 21, so that the reagent pot 21 is in a low temperature environment, which is convenient for reagent preservation. For example, the bottom of the reagent pot 21 has a mounting position 213, and the refrigeration structure 24 is installed in the mounting position 213. Specifically, the refrigeration structure 24 includes a refrigeration component, which is located below the reagent tray 22 and deviates from the center of the reagent pot 21, and is used to refrigerate the reagent pot 21. Specifically, the refrigeration component has a cold end and a hot end, and the cold end of the refrigeration component is arranged below the reagent tray 22, for refrigerating the reagent tray 22, and the hot end of the refrigeration component is arranged at the transparent window 26. After the refrigeration component is energized, the cold end can generate cold air to cool the reagent tray 22, thereby realizing the refrigeration of the reagent in the reagent container; since refrigeration is required inside the reagent pot 21 to ensure reagent storage, and the outside of the reagent pot 21 is a normal temperature space, this will cause condensation water to form on the transparent window 26 and affect the scanning of the identification code scanner 3. After the heat generated by the hot end of the refrigeration component is transferred to the transparent window 26, the contact part of the transparent window 26 with the outside of the reagent pot 21 can be heated to avoid condensation water on the transparent window 26.

[0100] Optionally, the refrigeration structure 24 further includes a cold end radiator, which is arranged in the reagent pot 21 to accelerate the dissipation of cold, ensure that the cold is evenly distributed in the reagent pot 21, and ensure the refrigeration effect. Moreover, the cold end radiator is also located below the reagent tray 22, so that the refrigeration structure 24 can avoid occupying the space of the reagent container and ensure the number of reagent containers carried on the reagent tray 22. For example, the cold end radiator can be a cold end fan and / or a cold end fin, etc.

[0101] Optionally again, the reagent loading mechanism 2 also includes a hot end radiator 25 and a heat conducting component. The hot end radiator 25 is connected with the hot end of the refrigeration component and is positioned at the outside of the reagent pot 21, and the heat conducting component is connected with the hot end radiator 25 and corresponds to the outside of the scanning window 211. That is, the heat conducting component connects the hot end radiator 25 and the outside of the transparent window 26, so that heat is transferred to the transparent window 26 to avoid heat loss. It is understandable that the outside of the transparent window 26 is between the sample loading mechanism 1 and the reagent loading mechanism 2, and the transparent window 26 is in the reagent pot 21. For example, the hot end radiator 25 can be a hot end fan and / or a hot end heat sink or the like. The heat conducting component is made of a heat conducting material.

[0102] Optionally, a drain port 212 is provided at the bottom of the reagent pot 21, and the drain port 212 is used to discharge condensed water generated by the refrigeration structure 24. The drain port 212 can also discharge condensed water generated by other components of the reagent loading mechanism 2 to prevent condensed water from accumulating in the reagent pot 21 and affecting electrical safety.

[0103] As an operative embodiment, the reagent loading mechanism 2 further comprises a reagent pot cover 27, which is covered on the reagent pot 21. The reagent pot cover 27 has a plurality of reagent suction holes 272, which are arranged along the radial direction of the reagent disk 22 and are located in a straight line. The reagent pot cover 27 can avoid the loss of cold in the reagent pot 21, ensure the refrigeration effect, and save costs. Moreover, the reagent pot cover 27 has a plurality of reagent suction holes 272, which are arranged along the radial direction of the reagent disk 22 and are located in a straight line, and the dispensing needle can extend into any reagent suction hole 272 to absorb the reagent. The plurality of reagent suction holes 272 can enable the dispensing needle to absorb the reagent in the reagent containers at different positions. The number of reagent containers on the reagent disk 22 can be increased in this way. It is understandable that the multi-layer reagent container is nested layer by layer, and a plurality of reagent containers are also provided in the same radial direction of the reagent disk 22. Moreover, the reagent containers in the same radial direction correspond to a plurality of reagent suction holes 272, so that the dispensing needle can suck the reagent at any position without rotating, which is convenient for selection and saves time for transferring reagents. It should be noted that each reagent suction hole 272 is a reagent suction station, and the dispensing needle can suck the reagent at any reagent suction station.

[0104] In the embodiment, the reagent pot cover 27 has four reagent suction holes 272, the four reagent suction holes 272 are in the same straight line, and the four reagent suction holes 272 also extend in the radial direction of the reagent disk 22. When transferring reagents, the reagent storage drive structure 23 drives the reagent disk 22 to drive the reaction container thereon to rotate, so that the reaction container to be sucked of the reagent rotates to the reagent suction hole 272, and the four reagent containers correspond to the four reagent suction holes 272 respectively, and the dispensing needle can select the reagent suction hole 272 corresponding to the required reagent to suck the reagent. Moreover, the setting of the reagent suction hole 272 can also prevent the reagent pot cover 27 from opening too large, causing the cold in the reagent pot 21 to overflow.

[0105] Further, the reagent loading mechanism 2 also includes a switch cover 271, and the reagent pot cover 27 has a release opening for placing or taking out the reagent container, and the switch cover 271 is switchably located in the release opening of the reagent pot cover 27. The switch cover 271 is a small cover on the reagent pot cover 27. When the reagent in a certain reagent container on the reagent tray 22 needs to be supplemented, the switch cover 271 is opened, and the reagent container is taken out through the release opening. After the reagent is supplemented, the reagent container is placed on the reagent tray 22 through the release opening. This can facilitate the use of the operating personnel, and the loss of coldness in the reagent pot 21 can also be avoided simultaneously. Optionally, one end of the switch cover 271 is rotatably mounted on the reagent pot cover 27, and the other end of the switch cover 271 can rotate around the reagent pot cover 27 to open or close the release opening. Of course, in other embodiments of the present invention, the switch cover 271 can also be removed as a whole, fixed by locating pins etc.

[0106] Furthermore, the reagent pot cover 27 also includes a double-layer cover 273, which is arranged at the reagent suction hole 272 to prevent condensed water generated at the reagent suction hole 272 from dripping into the reagent container. The double-layer cover 273 includes a top pot cover and a bottom pot cover that are stacked, the top pot cover has a top opening, and the bottom pot cover has a bottom opening, and the top opening and the bottom opening are arranged correspondingly. The bottom opening is to facilitate the dispensing needle to absorb the reagent, and the reagent suction hole 272 is arranged corresponding to the bottom opening. When the fully automatic chemiluminescence immunoassay analyzer is in operation, the reagent disk 22 drives the corresponding reagent container to rotate to the bottom opening, and the dispensing needle extends into the reagent container through the bottom opening to absorb the reagent. After the absorption is completed, the dispensing needle leaves the bottom opening through the bottom opening.

[0107] Moreover, the size of the top opening is larger than the size of the bottom opening, and a drain hole is arranged on the bottom pot cover, and the drain hole is communicated with the drain port 212. The double-layer opening structure is arranged to avoid condensed water from dripping into the reagent container, and also to avoid a large amount of cold loss. There is an air flow area between the top pot cover and the bottom pot cover, and the air in the reagent pot 21 can flow freely in the air flow area. After the normal temperature air of the outside enters the air flow area through the reagent suction hole 272, the condensed water generated at the top opening can drip on the surface of the bottom pot cover, and be drained into the drain hole, and discharged through the drain port 212 at the bottom of the reagent pot 21. Optionally, the top pot cover and the bottom pot cover are also filled with heat-insulating materials such as heat-insulating cotton in addition to the drainage passage, to avoid the cold in the reagent pot 21 from overflowing.

[0108] See also Figure 2 , Figure 3 , Figure 7 and Figure 8 The present invention also provides a scanning method of a sample reagent loading scanning system, which is applied to a sample reagent loading system in any of the above embodiments; the scanning method includes a step of scanning an identification code of a reagent container and a step of scanning an identification code of a sample container 5, wherein:

[0109] The step of scanning the identification code of the reagent container includes: the sample loading mechanism 1 drives the scanning notch 14 to rotate so that the scanning notch 14 corresponds to the identification code scanner 3; the reagent loading mechanism 2 rotates and drives the multiple reagent containers to rotate to the scanning notch 14 in sequence; the identification code scanner 3 scans the identification code of the reagent container through the scanning notch 14;

[0110] The step of scanning the identification code of the sample container 5 includes: the sample loading mechanism 1 drives the plurality of sample containers 5 to rotate to positions corresponding to the identification code scanner 3 in sequence; and the identification code scanner 3 scans the identification code of the sample container 5 .

[0111] The sample reagent loading scanning system of the present invention can scan the identification code of the sample container 5 in the sample loading mechanism 1, and can also scan the identification code of the reagent container in the reagent loading mechanism 2. When scanning the identification code of the sample container 5, the sample loading mechanism 1 can drive each sample container 5 thereon to rotate, so that the reagent container passes through the identification code scanner 3 in sequence, so as to realize the scanning of the identification code of the sample container 5. Since the sample loading mechanism 1 is located outside the reagent loading mechanism 2, the sample loading mechanism 1 will inevitably block the identification code of the reagent container, so a scanning notch 14 is set on the sample loading mechanism 1. Before scanning the identification code of the reagent container, the scanning notch 14 is first driven by the sample loading mechanism 1 to move to the corresponding identification code scanner 3, and then the reagent loading mechanism 2 can drive each container thereon to move, so that the reagent container passes through the scanning notch 14 in sequence, so that the identification code scanner 3 can scan the identification code of the reagent container through the scanning notch 14. It can be understood that during the scanning process, the reagent pot 21 can remain stationary, and the transparent window 26 always corresponds to the identification code scanner 3.

[0112] Furthermore, before the step of scanning the identification code of the sample container 5 , the scanning method further includes an avoidance step, in which the reagent loading mechanism 2 drives the reagent container to rotate so that the gap between two adjacent reagent containers is aligned with the identification code scanner 3 .

[0113] Since the identification code scanner 3 is used to scan both the identification code of the sample container 5 and the identification code of the reagent container, it is necessary to avoid interference of the identification code of the reagent container with the identification code of the sample container 5 when scanning the identification code of the sample container 5. Therefore, it is necessary to rotate the reagent loading mechanism 2 to align the gap between two adjacent reagent containers with the identification code scanner 3, so that the identification code scanner 3 cannot scan the identification code of the reagent container.

[0114] Furthermore, after the step of scanning the identification code of the sample container 5 , the scanning method further includes matching the information of the identification code of the sample container 5 with the position information of the sample container 5 .

[0115] The identification code scanner 3 can scan the identification code of each sample container 5, match the information of the identification code of each sample container 5 and the position information of the corresponding sample container 5, and then record them in the main control device to facilitate subsequent sample detection.

[0116] Furthermore, after the step of scanning the identification code of the reagent container, the scanning method further includes matching the information of the identification code of the reagent container with the position information of the reagent container.

[0117] The identification code scanner 3 can scan the identification code of each reagent container, match the information of the identification code of each reagent container and the position information of the corresponding reagent container, and then record them in the main control device to facilitate subsequent sample detection.

[0118] Specifically, the identification code scanner 3 is fixed on the outside of the sample loading mechanism 1 and has a scanning area, which can be projected onto the sample loading mechanism 1 and the reagent loading mechanism 2. When scanning the identification code of the sample container 5, the reagent loading mechanism 2 first drives the reagent container on it to rotate so that the space between two adjacent reagent containers corresponds to the identification code scanner 3, and then the sample loading mechanism 1 drives the sample container 5 to rotate to the identification code scanner 3 in turn for scanning. After the scanning is completed, the identification code scanner 3 matches the information of the identification code of each sample container 5 and the position information of the corresponding sample container 5. When scanning the identification code of the reagent container, the sample loading mechanism 1 is first controlled to rotate so that the scanning notch 14 corresponds to the identification code scanner 3 to ensure that the scanning window 211, the scanning notch 14 and the identification code scanner 3 correspond; then the reagent loading mechanism 2 is controlled to drive the reagent container to rotate to the scanning notch 14 in turn for scanning, and then the information of the identification code of each reagent container and the position information of the corresponding reagent container are matched. After the identification code of the sample container 5 and the identification code of the reagent container are scanned, the sample detection operation can be performed.

[0119] As an embodiment, when the sample container 5 is loaded into the sample loading mechanism 1, the scanning method further includes the following detection steps:

[0120] Control the transmitter 41 to transmit a signal;

[0121] If the receiver 42 is able to receive the signal, the sample container 5 is loaded in place;

[0122] If the receiver 42 fails to receive the signal, the sample container 5 is not loaded into place, and a reinstallation alarm is issued.

[0123] The use of the transmitter 41 and the receiver 42 can detect whether the sample container 5 is installed in place, so as to ensure the smooth operation of the sample loading mechanism 1. Specifically, after the transmitter 41 transmits a signal, if the receiver 42 does not receive the signal, it means that there is a sample container 5 between the receiver 42 and the transmitter 41, and the signal transmitted by the transmitter 41 will be reflected by the sample container 5. At this time, the sample container 5 is not installed in place, and the sample container 5 will not be allowed to move. The receiver 42 sends a reinstallation alarm to remind the user to reinstall the sample container 5 or replace the sample container 5; if the receiver 42 receives a signal, it means that the top of the sample container 5 is above the limit height. At this time, there is no sample container 5 blocking the receiver 42 and the transmitter 41, indicating that the sample container 5 is installed in place and the sample container 5 is allowed to move.

[0124] The present invention also provides a chemiluminescence analyzer, comprising a sample and reagent loading and scanning system as in any of the above embodiments, a dispensing needle for aspirating and discharging samples and reagents, an incubation photometric device for incubation and luminescence detection, a magnetic separation and cleaning device for separation and cleaning, and a transport grabbing cup device for transporting the reaction container; the dispensing device transfers the sample and reagent in the sample and reagent loading and scanning system to an empty reaction container respectively, the transport grabbing cup device transfers the reaction container to the incubation photometric device for incubation, after the incubation is completed, the transport grabbing cup device also transfers the incubated reaction container to the magnetic separation and cleaning device for separation and cleaning, and transfers the separated and cleaned reaction container to the incubation photometric device for luminescence detection, and finally obtains various parameters of the sample.

[0125] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0126] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
