Example 1

As shown in FIGS. 1 and 2 , the analyzer of the present invention includes a carrying module 100 for carrying the cuvette 120 and a reagent tray module 500 arranged on one side of the carrying module 100 , and the reagent tray module 500 carries a chemiluminescence reaction in the reagent tray module 500 . reagent. Wherein, the number of the carrying module 100 and the reagent tray module 500 is one. Compared with the existing luminescence analyzer, all the steps of the chemiluminescence reaction test can be integrated in one incubation tray, so that the analyzer of the present invention can be completed. The structure is simpler and more compact, enabling it to achieve the purpose of miniaturization.

It should be noted that the operations for the cuvette 120 according to the present invention include: the operation of pushing the cuvette 120 into the carrying module 100 , the operation of adding a sample to the cuvette 120 , and the operation of adding a diluent to the cuvette 120 One or more of the operations of adding reagents to the cuvette 120 , incubating and reading the cuvette 120 , optically detecting the cuvette 120 , and pushing the cuvette 120 out of the carrier module 100 .

In one embodiment, the analyzer of the present invention is further provided with various operation units for realizing chemiluminescence reaction detection at positions corresponding to the operation positions around the carrier module 100 . Specifically, the operation unit includes a cuvette loading module 400 , a sample transfer arm module 200 , a light detection module 600 , a cuvette removal module 900 and a reagent arm 300 , which are sequentially arranged along the circumferential direction of the carrier module 100 .

Among them, the cuvette loading module 400 is used for arranging the disordered cuvette 120 neatly and then pushing it into the carrying module 100 , and the sample transfer arm module 200 is used for adding a sample to the cuvette 120 or sucking the diluted sample from the cuvette 120 . Sample, the optical detection module 600 is used for optical detection of the substance in the cuvette 120, the cuvette removal module 900 is used to push the detection cuvette 120 on the carrier module 100 out of the carrier module 100, and the reagent arm 300 is used to remove the reagent The reagents in the disk module 500 are transferred to the cuvette 120 of the carrier module 100 . In this embodiment, the cuvette 120 rotates with the carrying module 100 to a position corresponding to each of the above-mentioned operation modules.

Of course, it is also conceivable to move the cuvette to a position on the carrying module corresponding to each of the above-mentioned operation modules by using a mechanical gripper, so as to realize the chemiluminescence reaction.

The number of the carrier module 100 is one. By arranging each component around its circumference to perform corresponding operations, the entire chemiluminescence reaction can be completed on one carrier module 100, thereby realizing the miniaturization of the analyzer and simplifying the scheduling control of the remaining components.

The bearing module 100 will be described in detail below.

Taking the carrying module 100 shown in FIG. 2 as an example for illustration, in this embodiment, the carrying module 100 includes a carrying plate with a disc-shaped structure, which can rotate around its axis. A groove for carrying the cuvette 120 (ie, the cuvette placement groove 121 described below) is provided on the carrier plate. A plurality of grooves are provided along the circumference of the carrier disc. In addition, the carrier module 100 also includes a housing that does not rotate with the carrier disk.

The casing of the carrying module 100 is provided with an operation position 110, so the position of the operation position is fixed relative to the main body of the analyzer. An operation unit is provided at a position corresponding to the operation position 110, and the carrier module 100 makes the cuvette 120 in the cuvette placement groove 121 located at the operation position 110 through the rotation of the carrying plate, so that the operation unit corresponding to the operation position 110 can be used for the cuvette. 120 performs corresponding operations. Different cuvette 120 can be located in different operation positions 110 at the same time through the rotation of the carrier plate, so that different cuvette 120 can be operated at the same time.

The operation positions 110 in the present invention include but are not limited to cup feeding position 1, first sample position 12, second sample position 16, detection position 30, cup discard position 41, first reagent position 56, second reagent position 69 and the third reagent position 72. The numbers of these operation bits are for illustration only, and should not be construed as limiting the scope of protection of the present invention. Since the present invention starts from the cup feeding operation, the cup feeding position will be described first.

1. Into the cup position 1.

As shown in FIG. 2, the cup feeding position 1 is located at the quarter quadrant point of the carrier module 100, and the cuvette loading module 400 is correspondingly provided at the cup feeding position 1. The cuvette loading module 400 includes a cuvette storage module for storing cuvette 120 of the storage, as shown in FIG. 1 , the central axis of the storage is parallel to the line connecting the center of the carrier module 100 and the center of the reagent tray module 500 . The cuvette loading module 400 makes the cuvette 120 in the cuvette enter the cuvette entry position 1 .

Second, the sample position.

The sample position corresponds to the sample transfer arm module 200, and the sample transfer arm module 200 may be assigned to a plurality of sample loading positions. The sample transfer arm module 200 is disposed between the cuvette loading module 400 and the sample holder 210 described below.

In a specific implementation, the number of sample bits is two, that is, a first sample bit (sample bit 12 as shown in FIG. 1 ) and a second sample bit 16 . For example, a first sample position may be used to add a sample, and a second sample position may correspond to a diluted sample and aspirate the diluted sample.

In the event that the sample needs to be diluted, the original sample in the first sample position is diluted by the instrument by a predetermined factor (eg, 20 times, 100 times, etc.) and then sent to the second sample position. At this time, the sample transfer arm can draw a certain amount of diluted sample from the second sample position and transfer it to the empty cuvette in the first sample position, so as to complete the subsequent reaction process.

Thus, the analyzer of the present invention saves components for diluting samples in conventional analyzers. In conventional analyzers, there is generally a dedicated sample dilution area. Since the dilution of the sample generally requires a large dilution, additional dilution equipment is required to accommodate the large dilution of the sample volume. When the sample needs to be diluted, first move the sample to the dilution area for dilution. The diluted sample is then transferred to the carrier tray for subsequent steps. However, in the present application, by using multiple sample positions on the carrier module to integrate the functions of sample addition and dilution at the same time, the component space is greatly saved.

Of course, according to actual needs, more than two sample bits can also be set. For example, set four sample bits. At this time, the first and second sample positions are used to set the sample, and the third and fourth sample positions are used to accommodate the diluted sample. Alternatively, if the required dilution factor is larger, it can also be proposed that the second to fourth sample positions are used to accommodate the diluted sample.

3. Reagent position.

The reagent position is located at the intersection of the virtual arc with the fulcrum of the reagent arm 300 as the center and the carrier module 100 .

The virtual arc takes the fulcrum of the reagent arm as the center and the cantilever of the reagent arm as the radius. Specifically, the intersection of the virtual arc and the carrier module is the intersection of the virtual arc and the circular contour formed by the plurality of grooves. Therefore, the intersection with the carrier module corresponds to the groove.

The first reagent can be added to the reaction cup 120 at the first reagent position 56 . The second reagent can be added to the cuvette 120 at the second reagent position 69, and the second reagent or the third reagent can be added to the cuvette 120 at the third reagent position 72.

The first reagent described in the present invention is not only one reagent, but may include a variety of different reagents. For example, it includes a first reagent R1, a first reagent R2, a first reagent R3, a diluent, and the like.

Here, it is exemplarily proposed that the reagent added to the second reagent position and the third reagent position is different from the reagent added to the first reagent position. The second reagent position and the third reagent position can be used to add the same second reagent to the cuvette.

According to the different detection items to be performed on the object to be tested in the reaction cup, the analyzer selects the second reagent position or the third reagent position to add the same second reagent according to the time of the detection item. For example, the second reagent position is used for reagent additions for routine items. The third reagent position is used for adding reagents for rapid detection items. As a result, the position conflict of the cuvette between different items is avoided, thereby realizing flexible matching of the duration of different detection items.

It should be noted that the second reagent described in the present invention is not only one reagent, but may include multiple reagents. For example, the second reagent R4 (such as a general reagent) and the second reagent R are included.

It is also conceivable that the reagents added to the second reagent site and the third reagent site are different from each other. At this point, for example, the third reagent position can be set for adding diluent, so that the first reagent position can provide more reagent. In this case, the timing of the quick diagnosis item can be matched by the scheduling of the reaction vessel by the mechanical gripper.

Fourth, the detection bit 30.

The detection bit 30 corresponds to the light detection module. The light detection module is arranged on the side of the carrying module away from the cuvette loading module, and the light detection module is close to the sample rack. The light detection module 600 detects the luminescence signal of the cuvette 120 located at the detection position 30 (the cuvette 120 to which the corresponding reagent has been added).

It should be noted that, in some embodiments (as shown in FIG. 1 ), the light detection module 600 is directly located on the detection position, so the light-emitting signal of the cuvette 120 directly enters the light detection module 600 for detection.

It can be understood that, in other embodiments, the light detection module 600 is not directly located on the detection position, but the luminescence signal of the cuvette 120 is collected and sent to the light detection module 600 by other means.

5. Abandoned cup position 41.

The cuvette removal module 900 on the carrier module 100 is disposed on the side of the carrier module away from the cuvette loading module, and the cuvette removal module is close to the reagent tray module. The cuvette removal module enables the cuvette 120 located at the discarding position 41 to leave the carrier module 100 .

Here, the cup feeding position, the first sample sample position 12 , the second sample position 16 , the detection position 30 , the cup discard position 41 , the first reagent position 56 , the second reagent position 69 and the third reagent in the operation position 110 Bit 72 is set sequentially in a counter-clockwise direction.

Of course, the operating position 110 can also be set in a clockwise direction, and it is only necessary to adjust the settings of other components of the instrument.

The second side (the right side as shown in FIG. 2 ) of the carrying module 100 is provided with a reagent disk module 500 for carrying reagents, and the number of reagent arms 300 is multiple. As shown in FIG. 1 , the route of each reagent arm 300 for transferring the reagent is an arc.

Specifically, the number of intersections of the plurality of virtual arcs with each reagent arm as the center of the fulcrum and the carrier module 100 are different from each other. In addition, the number of intersections of the plurality of virtual arcs centered on the fulcrum of each reagent arm and the reagent disk module 500 are different from each other. The virtual arc takes the fulcrum of the reagent arm as the center and the cantilever of the reagent arm as the radius. Multiple intersection points realize the flexible matching of the instrument and the time of different inspection items. The instrument can select the required intersection point according to the time required for the inspection item.

For example, a virtual arc centered on the fulcrum of one of the reagent arms has two intersections with the carrier module 100 and one intersection with the reagent disk module, and a virtual arc centered on the fulcrum of the other reagent arm has two intersections with the carrier module 100 One intersection and three intersections with the reagent disc module 500 .

The reagent suction position is located at the intersection of the virtual arc with the reagent arm 300 as the center and the reagent disk module 500 .

In one embodiment, as shown in FIG. 3 , the sample transfer arm module 200 includes an interconnected sample transfer arm 202 and a drive system.

The sample-moving arm 202 moves along the Z-axis under the driving of the Z-axis up-and-down movement mechanism 206 , and the sample-moving arm 202 and the Z-axis up-and-down movement mechanism 206 move along the X-axis under the driving of the X-axis plane movement mechanism 204 . The arm 202 , the Z-axis up-and-down motion mechanism 206 and the X-axis plane motion mechanism 204 move along the Y-axis on the Y-axis plane motion mechanism 205 .

One of the columns (the right side as shown in FIG. 2 ) or one of the rows of the sample racks 210 can be set as the emergency sample racks 220 for carrying emergency sample test tubes, and other columns or other rows of the sample racks 210 can be set as the emergency sample racks 220 for carrying ordinary sample tubes. Common sample holder for sample tubes. The emergency sample in the emergency sample test tube can be transferred to the cuvette 120 in the carrying module 100 by the sample transfer arm module 200 in preference to the common sample in the common sample test tube.

The sample rack 210 and the tip accommodating chamber 230 utilize the space occupied by the three-axis motion assembly 203 in the XY plane, so that the volume of the analyzer can be further reduced.
