Description

Analyzer for chemiluminescence detection

Technical Field

The utility model relates to a chemiluminescence detects technical field, especially relates to an analysis appearance for chemiluminescence detects.

Background

The light-activated chemiluminescence detection is a homogeneous immunoassay technology, and is beneficial to quickly and fully completing immunoreaction.

Currently, such detection is generally performed using a fully automatic light-activated chemiluminescent detection device. The full-automatic detection device has the advantages that the working process of the detection device does not need human intervention or external intervention, and the accuracy and the high efficiency of the detection process are favorably ensured.

Existing detection devices for fully automated light-activated chemiluminescence detection are designed specifically for large hospitals or medical facilities for detecting as many samples as possible (e.g., at least about 100) simultaneously in the detection device. However, this usually requires the detection device to be provided with a plurality of (at least 2) incubation trays, which are typically arranged on the table top, distributed over each other. Although this apparatus can handle a very large number of samples simultaneously, each sample is subjected to a very large number of rotational movements on 2 incubation plates and requires transfer between 2 incubation plates. This makes the processing time for each sample relatively long. In addition, the detector has many structural components, so that the detector is relatively complex to fit with each other and is easy to make mistakes. Thus, such meters are only suitable for use in large hospitals where large numbers of samples are required to be processed densely, whereas for small hospitals or other small medical facilities, the efficiency is less if relatively few samples (e.g. less than 50) are to be processed.

There are also solutions in the prior art where multiple reagent disks or incubation disks are arranged coaxially. However, in this solution, the outermost disks would have a very large diameter. This results in a relatively poor stability of its operation, for example, prone to inaccurate positioning. In this case, many structural components are more prone to scheduling problems when fully automated mating is performed.

Through the utility model discloses an above-mentioned analysis appearance, in whole testing process, reaction vessel all is located a and bears the weight of the mechanism. The detection process is advanced by rotating the reaction vessel to a different position by the carrier mechanism. Alternatively, the reaction vessels on the carrier may be moved to different receiving positions by a mechanical gripper for different detection steps. Because the whole detection process can be carried out on one bearing mechanism, the structure of the analyzer can be effectively simplified, and the volume and the weight of the whole analyzer are allowed to be greatly reduced. In addition, the matching between the structural components can be simpler, and errors and mistakes in control are not easy to occur.

fig. 2 shows a schematic top view of another embodiment of an analyzer for chemiluminescence detection according to the invention, comprising a carrying mechanism.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Fig. 1 and 2 schematically show a chemiluminescence analyzer (hereinafter referred to as "analyzer") 1 according to the present invention, which is particularly useful for fully automatic photoexcited chemiluminescence detection.

As shown in fig. 1 and 2, analyzer 1 includes a frame 160 for supporting other structural components of analyzer 1. A rotatable support 70 is arranged on the machine frame 160, which support 70 can be configured, for example, in the form of a disk, so that it can rotate about its own center. The analyzer 1 may further include a sample dispensing mechanism 20, a reaction vessel dispensing mechanism 60, a reagent tray (e.g., one reagent tray 110) for holding a reagent to be used, at least one reagent dispensing mechanism (e.g., two reagent dispensing mechanisms 80 and 120), a light detecting mechanism 150, and a reaction vessel removing mechanism 140, which are located on the rack 160 and are disposed around the one carrier mechanism 70. By providing these structural parts to surround the support means 70, corresponding regions can be formed in different parts of the support means 70. For example, the portion of the carrier mechanism 70 corresponding to the reaction vessel dispensing mechanism 60 forms a reaction vessel dispensing region a 1. The portion of the carrier mechanism 70 corresponding to the sample dispensing mechanism 20 (and reagent tray 110) forms a sample dispensing zone a 2. The portions of the carrier mechanism 70 corresponding to the

reagent dispensing mechanisms

80, 120 form a reagent dispensing zone a 3. The portion of the support mechanism 70 corresponding to the light detection mechanism 150 forms a light emission detection area a 4. The portion of the carrier mechanism 70 corresponding to the reaction vessel removal mechanism 140 forms a reaction vessel removal area a 5.

It should be understood that the various regions described above do not change with the rotation of the carrier 70.

It should also be understood that the carrier mechanism 70 may be configured as a robotic arm or the like, and may be operated in any suitable manner, including translation or a combination of translation and rotation, to deliver reaction vessels into the respective zones.

The sample dispensing mechanism 20 includes a dispenser 23 for sucking a liquid, and a first axially movable support 21 and a second axially movable support 22 for moving the dispenser in a horizontal direction. By a first axial movement bracket 21 and a second axial movement bracket 22 extending perpendicularly to each other. It is obviously possible to provide that the first axially mobile carriage 21 is a cantilever movable along the second axially mobile carriage 22, and that the distributor 23 is mounted at the end of the movable cantilever. Alternatively, the boom movable along the first axial direction moving the support 21 while moving the support 22 in the second axial direction, and the distributor 23 is installed at the end of the movable boom. Thereby allowing the dispenser 23 to move horizontally relatively freely within a certain range. Within this range, sample racks for placing samples, such as the general sample rack 30 and the preferential sample rack 40 in fig. 1, may be provided. Within this range, a tip holder 50 for holding disposable tips may also be provided. The tip rack 50 may also include a tip disposal area 51. In addition, the above-described sample distribution area a2 is also within this movement range of the dispenser.

Here, the sample holder may be in communication with the environment outside the analyzer 1. In particular, the housing of the analyzer is provided with a void that mates with the sample holder, so that the sample holder is directly exposed to the ambient air. This facilitates on the one hand the reception of the sample from the outside and on the other hand also allows the sample on the sample holder to be kept at ambient temperature (typically room temperature) for more accurate detection.

In the above-described sample distribution region, a plurality of sample bits, for example, 2 sample bits, i.e., a first sample bit and a second sample bit, may be set. The sample position is the intersection point of the projection of the movement range of the cantilever on the analyzer and the contour of the bearing mechanism. For example, the carrier mechanism 70 may be rotated to the first reaction vessel at the first sample position to add the pre-sample (i.e., undiluted sample) from the sample rack to the first reaction vessel via the sample dispensing mechanism 20. Then, the carrier mechanism is rotated until the first reaction container is located in the reagent dispensing area a3, so as to add a reagent as a diluent into the first reaction container, and obtain a diluted sample in the first reaction container. Thereafter, the carrier mechanism 70 may be rotated again until the first reaction container is located at the second sample position, and the diluted sample in the first reaction container is added to another reaction container located at the first sample position as the sample to be detected by the sample dispensing mechanism 20. Thereby, a separate sample dilution device may be omitted.

It will be appreciated that, if desired, multiple dilutions between the first and second sample positions may be performed to obtain the sample to be tested.

It will also be appreciated that more sample sites may be provided to perform multiple dilution operations between each sample site to obtain a sample to be tested.

The priority sample rack may be used, for example, to place emergency samples. Here, the priority sample rack may be a sample rack designated by a user among a plurality of general sample racks. It is of course also conceivable to provide a separate preferential sample holder 40 which is closer to the carrier 70 than the generic sample holder 30. When the sample is placed on the priority sample rack 40, the analyzer 1 can automatically select to test the sample on the priority sample rack 40 first, and then test the sample on the general sample rack 30.

The pipette holder 50 is disposed between the sample holder and the carrier mechanism 70. The tip disposal area 51 is in turn provided on the side of the tip holder 50 adjacent to the carrier mechanism 70.

By the above arrangement, it is advantageous to simplify and optimize the moving path of the dispenser 23 in the sample dispensing mechanism 20.

In addition, the sample dispensing mechanism 20 may further include a mechanism operable to control the elevation and lowering of the dispenser 23 in the vertical direction to achieve engagement of the dispenser 23 with the sample rack, tip rack, and the portion of the carrier mechanism in the sample dispensing zone A2.

As shown in fig. 1 and 2, the above-described reaction container dispensing mechanism 60 includes a conveyor 63 adjacent to the reaction container dispensing area a1 of the carrying mechanism 70, a finisher 62 located above the conveyor 63, and a storage 61 connected to the finisher 62. The storage 61 is used for storing reaction vessels to be used. The collator 62 may receive reaction vessels from the store 61 (e.g., by an additional conveyor) and position the reaction vessels in a particular orientation. The conveyor 63 can receive the reaction vessels from the collator 62 and move them into the receiving positions 71 on the carrier 70. As shown in fig. 1, a plurality of receiving positions 71 may be provided on the carrier 70. These receiving locations 71 are arranged equidistantly spaced apart from each other in the circumferential direction.

In the embodiment shown in fig. 1, the memory 61 is located on the left side of the finisher 62 in the top view. The memory 61 extends in the longitudinal direction, or is disposed parallel to the longitudinal direction.

In the embodiment shown in fig. 2, the storage 61 is located on the lower side of the finisher 62 in plan view, overlying the carrier mechanism 70. The memory 61 extends in the short side direction, or is disposed parallel to the short side direction. This arrangement is more compact.

The reagent disk 110 is adjacent to but spaced from the reagent dispensing region a3 of the carrier mechanism 70. A first reagent dispensing mechanism 120 and a second reagent dispensing mechanism 80 are provided spaced apart from each other in the space above the chassis 160 between the reagent disk 110 and the carrier mechanism 70. The first and second

reagent dispensing mechanisms

120, 80 are respectively mounted on either side of a line connecting the carrier mechanism 70 and the centre of the reagent disk 110. The first and second

reagent dispensing mechanisms

120, 80 may, for example, be configured with reagent arms extending laterally from a mounting point, with a liftable reagent dispenser (not shown) mounted at the extended end of the reagent arms. The reagent arm may be rotated about the mounting, forming a reagent dispensing path P of the reagent dispenser as shown in figure 1.

In the preferred embodiment shown in fig. 1, the first reagent dispensing mechanism 120 is upstream in the direction of rotation of the carrier mechanism relative to the second reagent dispensing mechanism. That is, the first reagent dispensing mechanism 120 is on the lower side of the top view in fig. 1, and the second dispensing mechanism 80 is on the upper side of the top view in fig. 1. The first reagent dispensing mechanism 120 may be used, for example, to dispense a reagent that is specific to a single test item, referred to herein as a first reagent. The second reagent dispensing mechanism 80 may be used, for example, to dispense a reagent, referred to herein as a second reagent, that is required for each test item. It is noted herein that the foregoing first and second reagents are merely illustrative of the role of the first and second reagent dispensing mechanisms and should not be construed as limiting the use of the first and second reagents themselves. The first and second reagents may be configured according to the needs of the user.

Referring to fig. 2, a first reagent dispensing location L1 is formed in an area where the carrier mechanism 70 overlaps the reagent dispensing path of the first reagent dispensing mechanism 120. Accordingly, a first reagent catch site is formed in a region where the reagent disk 110 overlaps with the reagent dispensing path of the first reagent dispensing mechanism 120, for example, there are a plurality of first reagent catch sites L4 and L5. When the carrier mechanism 70 is rotated to the position where the first reaction container is located at the first reagent dispensing position L1, the first reagent dispensing mechanism 120 takes the corresponding first reagent from at least one of the first reagent taking positions L4 and L5, moves it to the first reagent dispensing position L1, and adds the first reagent to the first reaction container.

In addition, a second reagent dispensing site is formed in a region where the carrier mechanism 70 overlaps with the reagent dispensing path of the second reagent dispensing mechanism 80, and there are a plurality of second reagent dispensing sites L2 and L3, for example. Accordingly, the second reagent acquisition site L6 is formed in a region where the reagent disk 110 overlaps with the reagent dispensing path of the second reagent dispensing mechanism 80. When the carrier mechanism 70 is rotated to the first reaction container at one of the second reagent dispensing positions L2 and L3, the second reagent dispensing mechanism 80 takes the corresponding second reagent from the second reagent take position L6 and moves it to the corresponding first reagent dispensing position to add the second reagent to the first reaction container.

In a preferred embodiment, a cleaning mechanism 130 for cleaning the reagent dispensers is provided between the reagent disk 110 and the carrier mechanism 70. The washing mechanism 130 is preferably located on the reagent dispensing path P. This arrangement advantageously simplifies the working trajectory of the

reagent dispensing mechanism

80, 120.

In the plan view shown in fig. 1, the reaction vessel distribution mechanism 60 and the reaction vessel distribution region a1 are located on the upper side of the carrier mechanism 70. The sample dispensing mechanism 20 is located on the left side of the carrier mechanism 70, and the sample dispensing region a2 is correspondingly formed on the left side, preferably the upper left side, of the carrier mechanism 70. The reagent disk 110 is formed to the right of the carrier mechanism 70 with the

reagent dispensing mechanisms

80, 120 and the corresponding reagent dispensing zone a 3. The photodetection mechanism 150 and the corresponding luminescence detection zone a4, and the reaction vessel removal mechanism 140 and the reaction vessel removal zone a5 are formed on the lower side of the carrying mechanism 70, wherein the photodetection mechanism 150 and the corresponding luminescence detection zone a4 are closer to the sample distribution zone a2 (i.e., on the lower left side), and the reaction vessel removal mechanism 140 and the reaction vessel removal zone a5 are closer to the reagent distribution zone A3 (i.e., on the lower right side as viewed in fig. 1 or as viewed in fig. 2). For the arrangement shown in fig. 1 and 2, the lower side of the top view is the side of the analyzer that is closer to the user. The above arrangement may also be changed in mirror image in the up-down or left-right direction in plan view, as necessary.

In an alternative embodiment, the reagent disk 110 may also be arranged concentrically with the carrier 70 inside the carrier 70. Thus, the bearing mechanism 70 is formed substantially in a ring shape. The

reagent dispensing mechanisms

80, 120 are disposed between the reagent disk 110 and the carrier mechanism 70. Thus, reagent dispensing region A3 is concentric with carrier mechanism 70.

As shown in fig. 2, the reagent disk 110 is covered above with a reagent disk housing including a slide door 111 slidably opened. The sliding door 111 is configured substantially in the shape of a sector, occupying 1/4 the entire reagent disk housing. A rotary handle 112 is provided on the sliding door 111. The rotating handle 112 extends outside the housing of the entire analyzer 1 so that the user can access the rotating handle 112. For example, a user may cause the sliding door 111 to rotationally slide relative to the entire reagent disk housing, and thereby open, by rotating the rotating handle 112. This allows a portion of the reagent disk 110 that is originally covered with the slide door 111 to be exposed. The user may place a reagent to be used into a corresponding receptacle in the reagent tray 110, or place a reagent receptacle containing a reagent to be used into a corresponding reagent site in the reagent tray 110.

As also shown in fig. 2, a button 113 is provided on the housing of the analyzer 1. The button 113 is configured to drive the reagent disk 110 to rotate when pressed by a user. Thus, when a user adds a reagent to the reagent disk 110 by opening the formed opening through the sliding door 111, the reagent disk 110 can be rotated by pressing the button 113, thereby exposing a different container or a different reagent site in the reagent disk 110 for the user to add the reagent.

In addition, as shown in fig. 1 and 2, a control module 10 is disposed at the upper left of the entire analyzer 1. The control module 10 can be used to control the operation of the various structural components of the analyzer 1 to implement the overall detection method (described in detail below). For example, the user may control the control module 10 (the central computer) by another computer (the upper computer) to implement the above working process. After the computer receives the information of the project to be tested, the corresponding work task is sent to the control module 10. The control module 10 schedules the various operating mechanisms (e.g., the reaction vessel dispensing mechanism 60, the sample dispensing mechanism 20, the

reagent dispensing mechanisms

80 and 120, the light detection mechanism 150, the reaction vessel removing mechanism 140, etc.) according to the items to be measured. In addition, after the computer receives the information on the item to be measured, the computer also transmits the required reagent information to the control module 10. The control module 10 performs calculation according to the received reagent information to obtain the time required for the reagent kit containing the corresponding reagent in the reagent tray 110 to be pushed to the corresponding reagent acquisition position. The control module 10 drives the corresponding motors of the reagent disk 110 to rotate according to the time, so that the reagent cartridges on the reagent disk 110 and the corresponding reaction containers on the carrying mechanism 70 are rotated to the corresponding positions at the preset time to add the reagents. The computer and control module 10 described above is included in the control system of the chemiluminescence analyzer 1.

The computer and control module 10 is provided with a storage medium for storing a computer program for executing the method of operation of the analyzer 1 and the carrier 70.

Alternatively, the user may directly operate the control module 10 to perform the above-mentioned operation.

In addition, as shown in fig. 1 and 2, a flow path block 90 is arranged at the upper right of the entire analyzer 1. The flow path module 90 may be used, for example, to supply a washing fluid to the washing mechanism 130 and discharge waste liquid in the washing mechanism 130, thereby ensuring the accuracy of detection.

In the embodiment shown in fig. 1 and 2, the sample dispensing mechanism 20 is disposed on one side of the carrier mechanism 70 along the long side direction of the analyzer 1, and the

reagent dispensing mechanisms

80 and 120 and the reagent disk 110 are disposed on the other side of the carrier mechanism 70 along the long side direction of the analyzer 1. The flow path block 90 is disposed behind the

reagent dispensing mechanisms

80 and 120 in the short side direction (or above the

reagent dispensing mechanisms

80 and 120 in a plan view). Further, the reaction well dispensing mechanism 60 is provided between the sample dispensing mechanism 20 and the flow path block 90 in the longitudinal direction of the analyzer 1.

Further, a case 100 is surrounded on all the structural components described above. A closed and light-tight environment is formed through the shell, so that efficient and high-accuracy detection is facilitated in the shell.

By means of the arrangement described above, an analyzer 1 can be realized which is as simple in construction as possible and as compact in layout as possible. Such an analyzer 1 can effectively reduce the size of the analyzer without reducing the size of the carrying mechanism. This volume can be reduced by at least 1/3 compared to prior art detection devices. Such an analyzer 1 can be used effectively in small hospitals and small medical facilities to improve the cost-effectiveness of the test.

In this context, the reaction vessel may be, for example, a test tube or a reaction cup or the like.

While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. The present invention is not limited to the particular embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
