The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).

In some embodiments of the present invention, a sample analysis device is provided. Referring to fig. 1, the sample analysis apparatus in some embodiments includes a sample part 100, a reagent part 200, a reagent dispensing part 300, a reaction part 400, a measurement part 500, a controller 600, and a display part 700; wherein: the sample part 100 is used for supplying a sample to be measured; the reagent component 200 comprises a reagent site for carrying reagent containers, the reagent component 200 for scheduling the carried reagent containers; the reagent dispensing unit 300 is used for dispensing a reagent in a reagent container, for example, sucking the reagent from the reagent unit 200 and dispensing the reagent into the reaction unit 400; the reaction unit 400 is configured to receive a sample to be tested provided by the sample unit 100 and a reagent dispensed by the reagent dispensing unit 300 to prepare a sample; the measuring unit 500 measures a sample; the controller 600 controls the sample unit 100, the reagent unit 200, the reagent dispensing unit 300, the reaction unit 400, the measurement unit 500, and the display unit 700 displays contents, screens, and the like.

The reagent part 200 will be described in detail below.

As described above, the reagent unit 200 has a plurality of reagent sites for carrying reagent containers or reagents. In some embodiments, the reagent component 200 can provide cooling or other functions to the reagent carried, such as maintaining a temperature between 2 and 16 degrees Celsius, thereby ensuring the activity of the reagent. Specifically, the reagent component 200 is used to maintain its internal temperature within the range required by the instructions for use of the reagent. In order to ensure the cooling effect, the reagent part 200 may be a closed structure, for example, the reagent part 200 may be provided with a cover capable of being opened and closed to realize heat preservation. The reagent unit 200 may have a reagent presence detector for detecting whether or not a reagent container is carried at the reagent site.

In some embodiments, the reagent member 200 may be a disk-like structure or a linear structure. For example, the reagent component 200 in some embodiments includes a reagent disk 210. Reagent dish 210 is the setting of discoid structure, can rotate and drive its reagent that bears and rotate. By the rotation of the reagent disk 210, the reagent can be transferred to the reagent aspirating position for the reagent dispensing unit 300 to aspirate. The reagent disk 210 may have a lid 211 that can be opened and closed, and when the lid 211 is opened, a user can put or take a reagent into or out of the reagent disk 210. For example, fig. 2 (a) and 2 (b) are schematic views of the reagent disk 210 with the cover 211 opened (the cover 211 is in an open state) and with the cover 211 closed (the cover 211 is in a closed state), respectively.

In some specific examples, the reagent disk 210 may include at least one circle of reagent track 212 capable of rotating, the reagent track 212 includes a plurality of reagent sites 210a for carrying reagents, and the reagent track 212 rotates to move reagent containers on the reagent sites 210a thereof — for example, fig. 3 (a) and 3 (b) are two examples. In some embodiments, the reagent disk 210 includes multiple turns of reagent tracks 212, each reagent track 212 being capable of independent rotation. Fig. 3 (a) shows an example in which the reagent disk 210 has one turn of the reagent track 212, and fig. 3 (b) shows an example in which the reagent disk 210 has two turns of the reagent track 212 that can rotate independently. The reagent rail 212 can rotate and drive the reagent container carried by the reagent rail to transfer, so as to rotate the reagent container to the reagent sucking position, so that the reagent dispensing component 300 can suck the reagent and dispense the reagent to the reaction part 400. The reagent disk 210 is further described below with reference to the drawings.

Referring to fig. 3 (a), in some embodiments, the reagent tray 210 includes a circle of reagent tracks 212, and the reagent sites 210a can be used for placing reagent cups 215, a reagent container, the reagent cups 215 each include one or more cavities for containing reagents required by the project test, and a reagent is placed in one of the cavities; the reagent disk 210 includes a corresponding driving assembly for driving the reagent rail 212 to rotate, and the driving assembly drives the reagent rail 212 to rotate, so as to rotate the cavity of the reagent cup 91 containing the reagent required by the project to a corresponding reagent sucking position. In one example, each of the reagent cups 91 includes at least a first cavity 215a for carrying a first reagent and a second cavity 215b for carrying a second reagent, for example, the reagent cup 215 includes at least a first cavity 215a for carrying a mixed reagent (not referred to as R1) and a second cavity 215b for carrying a trigger reagent (not referred to as R2); the reagent disk 210 comprises a first reagent absorption position and a second reagent absorption position different from the first reagent absorption position, and the reagent track 212 is driven to rotate so as to drive the reagent cup 215 to rotate, so that the first cavity 215a of the reagent cup 215 is rotated to the first reagent absorption position; the reagent track 212 is driven to rotate the reagent cup 215, so as to rotate the second cavity 215b to the second reagent sucking position. It is understood that the first and second blotting sites are within the scope of the blotting sites herein.

Referring to FIG. 3 (b), in some embodiments, the reagent disk 210 includes two independently rotatable reagent tracks 212, such as the inner and outer reagent tracks 212 and 212 shown in the figure. An outer reagent track 212, the reagent site 210a of which can be used to carry a first reagent container; the reagent station 210a of the outer reagent track 212 may be used to carry a second reagent container. The reagent disk 210 includes a corresponding drive assembly for driving the rotation of the outer ring of reagent tracks 212, the drive assembly driving the outer ring of reagent tracks 212 to rotate and bring the first reagent container into rotation to rotate the first reagent container to the first reagent uptake position; the reagent disk 210 further includes a corresponding drive assembly for driving the rotation of the inner ring of reagent tracks 212, which drives the inner ring of reagent tracks 212 to rotate and to rotate the second reagent container to the second reagent aspirating position. It is to be understood that the first reagent container and the second reagent container herein are both within the scope of the reagent container herein.

In the above description, two configurations of the reagent disk 210 are described, for example, fig. 2 (a) is an example of placing the reagent cup 215, fig. 2 (b) is an example of implementing the reagent disk 210 by a plurality of tracks capable of rotating independently, and it will be understood by those skilled in the art that the reagent disk 210 may also be implemented by a plurality of tracks capable of rotating independently, and at least one track or each track may be used to place the reagent cup 215, for example, fig. 4 is an example, and the reagent cup 210a of the inner track 212 and the reagent cup 210 of the outer track 212 may be used to place the reagent cup 215. By placing all the types of reagents required for one test item in the same reagent sipper 215, the management of the reagents can be facilitated. Of course, in other embodiments, the inner ring of the reagent track 212 may be used to place consumables such as syringe and diluent, and the outer ring of the reagent track 212 may be used to place the main reagents for testing, such as the mixed reagent and the trigger reagent mentioned above.

The reagent disk 210 is one, which can be separately provided outside the reaction part 400. In other embodiments, there may be more than one reagent disk 210, for example, there may be two reagent disks 210. In some examples where the reagent disk 210 has two, one reagent disk 210 may be used to exclusively carry the mixed reagent R1 and the other reagent disk 210 may be used to exclusively carry the trigger reagent R2.

The above are some of the descriptions of the reagent disk 210. The reagent disk 210 may rotate and dispatch a corresponding reagent required by the test item to a reagent sucking position corresponding to the reagent dispensing unit 300 by rotating during the working cycle, for example, dispatching a first reagent to a first reagent sucking position and dispatching a second reagent to a second reagent sucking position.

The reagent tray 210 needs to receive reagents to replenish reagents consumed during testing, as well as to unload reagents or discard, for example, empty reagent containers. In some examples, a user may add reagent to the reagent tray 210 through the cover 211 of the reagent tray 210 and remove reagent containers to be unloaded from the reagent tray 210.

To enable online real-time reagent loading, the reagent component 200 in other embodiments may include, in addition to the reagent disk 210, a reagent loading and unloading mechanism 250 and a transport mechanism 290; in these embodiments, the reagent disk 210 may retain its cover 211 or may be constructed such that its cover 211 is removed.

Referring to fig. 5 and 6, fig. 5 is a perspective view of the reagent disk 210, the reagent loading/unloading mechanism 250, and the transport mechanism 290 with a partial housing removed, and fig. 6 is a plan view of the reagent disk 210, the reagent loading/unloading mechanism 250, and the transport mechanism 290 with a partial housing removed. The reagent loading and unloading mechanism 250 may interact with the reagent disk 210, for example, for real-time reagent loading, and/or real-time reagent unloading (including unloading of reagent containers that still have reagent remaining, unloading of empty reagent containers, etc.); for example, in some embodiments, the reagent unloading mechanism 250 is used to store reagent containers to be loaded, or to store or discard unloaded reagent containers. The transport mechanism 290 transports the reagent pack between the reagent disk 210 and the reagent loading/unloading mechanism 250; for example, in some embodiments, the transport mechanism 290 is used to transport a reagent container to be loaded from the reagent load and unload mechanism 250 to the reagent tray 210, or to transport a reagent container to be unloaded from the reagent tray 210 to the reagent load and unload mechanism 250.

In some embodiments, in order to interact with the reagent loading and unloading mechanism 250, the reagent disk 210 further includes a reagent container access 231 and a power door 233 openably and closably disposed at the reagent container access 231; when the power door 233 is in the open state, the transport mechanism 290 can be allowed to transport the reagent container from the reagent loading and unloading mechanism 250 to the reagent disk 210 through the reagent container entrance 231, or the transport mechanism 290 can transport the reagent container from the reagent disk 210 to the reagent loading and unloading mechanism 250 through the reagent container entrance 231; at other times, the power door 233 may remain closed, thereby ensuring that the reagent disk 210 has a small heat loss and ensures its cooling effect. That is, the power door 233 is opened when a reagent vessel is taken in or put out from the reagent disk 210, and is closed at other times. Other structures and examples of the reagent disk 210 are described in detail above and will not be described further herein.

In some embodiments, the reagent off-load mechanism 250 is used to store reagent containers to be loaded and/or to receive unloaded reagent containers for subsequent storage or disposal. In some embodiments, the reagent unloading mechanism 250 is provided with a plurality of reagent stations including a storage location for storing reagent containers to be loaded or unloaded and a discard location for discarding reagent containers to be discarded, such as empty reagent containers unloaded from the reagent tray 210. The reagent loading and unloading mechanism 250 can be implemented in various ways, which will be described in detail below.

Referring to fig. 7, in some embodiments, the reagent loading/unloading mechanism 250 includes a base 251 and a storage portion 260. The storage unit 260 is used for storing or receiving a reagent container. In some embodiments, the storage portion 260 may be fixedly disposed on the base 251, that is, the storage portion 260 is fixed, for example, fig. 7 is an example. In other embodiments, the storage unit 260 may be movably disposed on the base 251, for example, the reagent loading/unloading mechanism 250 further includes a driving unit 252, and the driving unit 252 is configured to drive the storage unit 260 to move, for example, rotate or linearly move, relative to the base 251 — for example, fig. 8 is an example in which the storage unit 260 can rotate relative to the base 251, and fig. 10 is an example in which the storage unit 260 can linearly move relative to the base 251.

The storage part 260 may be movable relative to the base 251 or may be fixed as described above. The shape of the storage portion 260 may be a disk-shaped structure or a rectangular shape.

For example, in some embodiments, the storage portion 260 is a disk-shaped structure. Fig. 7 and 8 both show examples in which the storage portion 260 has a disk-shaped structure. The disk-shaped surface of the storage part 260 is provided with the above-mentioned plurality of reagent stations, which, as mentioned above, comprise a storage location 262 for storing reagent containers to be loaded or unloaded and a disposal location 263 for receiving reagent containers to be disposed of, which are unloaded from the reagent disk 210. The number of storage bits 262 is one or more, preferably the number of storage bits 262 is plural; similarly, the number of the discarding bits 263 is one or more, preferably, the number of the discarding bits 263 is one — for example, ten are stored bits 262 in fig. 7 and 8, and the discarding bits 263 is an example. In some embodiments, each reagent site of the reservoir 260 is annularly disposed about the disk-shaped center of the reservoir 260. In the case where the storage unit 260 is movable (e.g., rotatable) relative to the base 251, when the storage unit 260 is rotated, each reagent site on the storage unit is also rotated.

As yet another example, in some embodiments, storage 260 is rectangular-such as is the case in FIGS. 9 and 10. The rectangular surface of the storage section 260 is provided with a plurality of reagent stations as mentioned above, which similarly include a storage bit 262 for storing reagent containers to be loaded or unloaded and a discard bit 263 for receiving reagent containers to be discarded unloaded from the reagent disk 210. The number of storage bits 262 is one or more, preferably the number of storage bits 262 is plural; similarly, the number of the discarding bits 263 is one or more, preferably, the number of the discarding bits 263 is one — for example, the storage bits 262 are seven in fig. 9 and 10, and the discarding bits 263 is an example. In some embodiments, the reagent sites of the storage portion are arranged in a row.

The user can place a reagent container to be loaded into the storage location 262 of the storage section 260 and can also take out an unloaded reagent container from the storage location 262, while a reagent container to be discarded, e.g., an empty reagent container depleted of reagent, is transported from the reagent disk 210 to the discard location 263 of the storage section 260 to effect the discard process of the reagent container. In some embodiments, referring to FIG. 11, the discard bit 263 may be connected to the waste bin 265 via a passageway 264, and reagent containers received by the discard bit 263 are discarded to the waste bin 265 via the passageway 264. The waste bin 265 may receive information such as expired reagent containers, empty reagent containers, etc. In the instance where the storage portion 260 is movable relative to the base 251, the channel 264 is capable of moving with the disposal location 263 as the storage portion 260 is moved, e.g., in embodiments where the storage portion 260 is rotatable relative to the base 251, the channel 264 is configured to rotate with the disposal location 263; in embodiments where the storage portion 260 moves linearly relative to the base 251, the channel 264 is configured to move linearly with the disposal site 263. In embodiments where the channel 264 is movable with the disposal site 263, this facilitates placement and functional multiplexing of the waste bin 265 within the sample analysis device, e.g., the waste bin 265 may be used to receive discarded reagent containers and may also be used to receive used reaction cups.

In some embodiments, the reagent loading and unloading mechanism 250 further comprises a lid (not shown) for allowing a user to access the reagent or reagent container, for example, when the lid of the reagent loading and unloading mechanism 250 is opened, the user can remove the reagent from the reagent loading and unloading mechanism 250 or insert the reagent into the reagent loading and unloading mechanism 250.

The reagent loading/unloading mechanism 250 is described above, and the transport mechanism 290 will be described below.

The transport mechanism 290 transports the reagent container between the reagent disk 210 and the reagent loading/unloading mechanism 250. For example, the transport mechanism 290 is used to transport reagent containers to be loaded from the storage locations of the reagent loading and unloading mechanism 250 to the reagent disk 210 and/or to transport reagent containers to be unloaded from the reagent disk 210 to the storage locations of the reagent loading and unloading mechanism 250. There are a variety of implementations of the transport mechanism 290.

Referring to fig. 12 and 13, for example, in some embodiments, the transport mechanism 450 includes a two-dimensional moving mechanism 251 and a reagent container gripping portion 259; the two-dimensional moving mechanism 251 is capable of driving the reagent container gripping section 259 to perform one-dimensional movement (e.g., up and down directions of the paper plane in fig. 12) between the reagent disk 210 and the storage section 260, and driving the reagent container gripping section 259 to perform up and down movements (e.g., a direction perpendicular to the paper plane in fig. 12); the reagent container catching unit 259 is used to catch and drop reagent containers. In an example in which the transport mechanism 250 is capable of one-dimensional movement in the planar direction and vertical direction, the reagent loading/unloading mechanism 250 may be configured such that the storage unit 260 is capable of moving relative to the base 251.

For another example, referring to fig. 14, the transport mechanism 450 includes a three-dimensional moving mechanism 253 and a reagent container gripping section 259; the three-dimensional movement mechanism 253 can drive the reagent container gripping section 259 to move in three-dimensional directions; the reagent container gripping section 259 is used to grip and drop a reagent container. In an example in which the transport mechanism 250 is capable of three-dimensional movement, the reagent loading/unloading mechanism 250 may be configured such that the storage unit 260 is stationary.

The above description is of the reagent disk 210, the reagent loading/unloading mechanism 250, and the transport mechanism 290. The reagent disk 210, the reagent loading/unloading mechanism 250, and the transport mechanism 290 according to the present invention cooperate with each other, so that a test flow can be performed without interrupting the test flow when reagent is loaded or unloaded. For example, a user places a reagent container to be loaded on the storage location 262 on the storage portion 260, and the transport mechanism 290 transports the reagent container to be loaded from the storage location 262 on the storage portion 260 to the reagent tray 210 at an appropriate time, so that real-time reagent loading is realized without interrupting a test flow; likewise, the transport mechanism 290 transports the reagent containers to be unloaded from the reagent disk 210 to the storage location 462 on the storage section 460 at an appropriate timing for the user to take out, which does not affect and interrupt the normal test flow of the reagent disk 210; likewise, the transport mechanism 290 transports the reagent pack to be discarded from the reagent disk 210 to the discard position 263 on the storage portion 260 at an appropriate timing for the discarding process, which does not affect and interrupt the normal test flow of the reagent disk 210.

In some embodiments, the sample analysis device further includes a scanning portion 270, such as is illustrated in FIG. 15. The reagent container may be provided with a label, and the scanner 270 reads label information of the reagent container by sensing the label. The label of the reagent container stores reagent information corresponding to the reagent, wherein the reagent information or the label information at least comprises reagent types, reagent allowance and the like, and can also comprise information such as reagent container types, production dates, quality guarantee periods, batch numbers, serial numbers, bottle opening dates, a plurality of calibration curves and the like. Therefore, in some embodiments, the scanner 270 is configured to read reagent information of the reagent container by sensing label information of the reagent container in the reagent loading and unloading mechanism 260. In some embodiments, the scanner 270 is also used to write information into the label of the reagent container. The scanning section 270 may be an RFID reader, and the label of the reagent container may be an RFID label. The scanner 270 can assist in the completion of the information management function of the reagent.

The above are some of the descriptions of the sample analyzing apparatus.
