Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a sample analyzer according to an embodiment of the present application, and fig. 2 is a schematic structural diagram of a cup of the sample analyzer shown in fig. 1. The embodiment of the application provides a sample analyzer, which comprises a measuring mechanism 100, a dispatching mechanism 200, a reaction cup recycling mechanism 300, a waste liquid sucking mechanism 400 and a reaction cup bearing mechanism 500.

The measuring mechanism 100 is used for measuring a reaction solution carried by a reaction cup, and the reaction solution is prepared from at least a reagent and a sample. The dispatching mechanism 200 is used for dispatching the measured reaction cups to the cup throwing positions. The cuvette retrieval mechanism 300 has a retrieval inlet towards the cuvette position. The waste liquid sucking mechanism 400 is used for sucking the reaction liquid carried by the reaction cup at the cup throwing position. The cuvette carrier means 500 comprises a holding assembly 51 and a driving assembly 52. The drive assembly 52 is in driving connection with the support assembly 51, the drive assembly 52 being capable of driving the support assembly 51 to carry a cuvette in the cup position, and the drive assembly 52 being capable of driving the support assembly 51 to release a cuvette in the cup position so that it falls into the recycling inlet.

Then, after the dispatching mechanism 200 dispatches the reaction cup after the measurement to the cup throwing position, the reaction cup bearing mechanism 500 can bear the reaction cup, then the waste liquid absorbing mechanism 400 absorbs the tested reaction liquid or waste liquid in the reaction cup, and finally the reaction cup bearing mechanism 500 loosens the reaction cup at the cup throwing position so that the reaction cup falls into the reaction cup recycling mechanism 300, thereby completing the classified recycling of the solid waste and the liquid waste.

Therefore, according to the embodiment of the application, the waste liquid suction can be completed at the same station, namely the throwing cup position, and the reaction cup is thrown into the reaction cup recovery mechanism 300, so that the waste liquid suction liquid level is additionally set for the waste liquid suction mechanism 400 to suck the waste liquid, and the station on the sample analyzer can be reduced, so that the volume of the sample analyzer is reduced.

Of course, in the embodiment of the application, by completing two actions of sucking waste liquid and throwing the reaction cup into the reaction cup recycling mechanism 300 at the same station, the travel of the reaction cup required to be moved in the recycling process can be reduced, so that the efficiency of the sample analyzer is improved.

For example, please continue to refer to fig. 3 and 4, fig. 3 is a schematic structural view of the reaction cup supporting mechanism shown in fig. 2, and fig. 4 is a schematic structural view of the reaction cup supporting mechanism shown in fig. 2 from another perspective. The support assembly 51 may include a bracket 511 and a baffle 512. The support 511 includes a first support 5111 at the cup-throwing position. The baffle 512 includes a second support 5121 at the cup-throwing position. The baffle 512 is in driving connection with the drive assembly 52. Wherein the driving assembly 52 can drive the second bearing 5121 to move relative to the first bearing 5111 so as to clamp or unclamp the reaction cup at the cup throwing position. Further, the support member 51 can support the reaction cup at the cup-throwing position by clamping.

The technical solution of the embodiments of the present application will be further explained and illustrated in connection with one of the working flows of the support assembly 51:

in a first step, the driving assembly 52 drives the shutter 512 to move to a clamped state with respect to the bracket 511.

In a second step, the dispatching mechanism 200 dispatches the measured cuvette to the cuvette position such that the measured cuvette is held by the baffle 512 and the holder 511.

In the third step, after the dispenser 200 is moved to another position for avoidance, the waste liquid sucking mechanism 400 sucks the reaction liquid from the reaction cup held by the holding member 51.

Fourth, the waste liquid sucking mechanism 400 is reset, and the driving assembly 52 drives the baffle 512 to move to an open state relative to the bracket 511, so that the reaction cup at the cup throwing position falls into the reaction cup recycling mechanism 300.

Finally, repeating the first step to the fourth step to complete the recovery of the batch reaction cups.

It will also be appreciated that during actual operation of the sample analyzer, the first and second steps described above may be performed simultaneously, i.e., the scheduling mechanism 200 may be configured to schedule the measured cuvette to the cuvette position while the drive assembly 52 drives the shutter 512 to move to the clamped state. The first step and the second step may be performed in reverse order, that is, the scheduling mechanism 200 schedules the measured reaction cup to the cup throwing position, and the driving assembly 52 drives the baffle 512 to move to the clamping state, which is not limited in the embodiment of the present application.

In some embodiments, the baffle 512 further comprises a pusher 5122. The pushing member 5122 is connected to the second supporting portion 5121 such that when the second supporting portion 5121 moves to release the reaction cup located at the cup throwing position, the pushing member 5122 moves to push the reaction cup located at the cup throwing position away from the first supporting portion 5111. Therefore, when the second support portion 5121 and the first support portion 5111 release the reaction cup, the reaction cup can be prevented from being retained on the first support portion 5111, and the reaction cup at the cup throwing position can not be recovered normally.

For example, in the actual operation, after the waste liquid sucking mechanism 400 sucks the waste liquid in the reaction cup at the cup throwing position, the reaction cup may be adsorbed on the first supporting portion 5111 due to static electricity or the like, so that the reaction cup still cannot fall into the reaction cup recycling mechanism 300 normally after the second supporting portion 5121 releases the reaction cup.

In addition, in the actual operation process, there may be some annular protrusions at the middle part of the outer side wall of the reaction cup or at the cup opening, so after the second support portion 5121 releases the reaction cup, the annular protrusions of the reaction cup are blocked on the first support portion 5111 and cannot fall off. It may also be that the clamping force of the first support portion 5111 and the second support portion 5121 on the reaction cup is too large, so that the reaction cup still adheres to the first support portion 5111 after the second support portion 5121 releases the reaction cup. Of course, it is also possible that the two or three factors mentioned above act together to cause the second support 5121 to release the reaction cup, and then the reaction cup remains on the first support 5111, but the reaction cup is well prevented from remaining on the first support 5111 by the pushing member 5122 in the embodiment of the present application, so as to improve the reliability of the sample analyzer when the reaction cup is recovered.

It can be further appreciated that, in the embodiment of the present application, the pushing member 5122 is disposed on the second supporting portion 5121, so that the pushing member 5122 and the baffle 512 can share one driving component 52, thereby reducing the power source on the sample analyzer, and finally making the sample analyzer smaller.

Some alternative configurations of the pusher 5122 will be further explained and illustrated below in connection with one of the ways in which the baffle 512 and the bracket 511 cooperate to clamp or unclamp the cuvette.

The baffle 512 can move towards the direction close to the first bearing portion 5111, so that the first bearing portion 5111 and the second bearing portion 5121 cooperate to clamp the reaction cup located at the cup throwing position, and the driving assembly 52 can drive the second bearing portion 5121 to move towards the direction far away from the first bearing portion 5111, so that the reaction cup located at the cup throwing position can fall.

At this time, the baffle 512 further includes a first connection portion 5123. The first connection portion 5123 includes oppositely disposed first and second ends. The first end is connected to the second supporting portion 5121, the second end is located at a side of the first supporting portion 5111 away from the second supporting portion 5121, and the second end is fixedly connected to the pushing member 5122.

Then, when the second support 5121 approaches the first support 5111 to clamp the reaction cup, the pushing member 5122 can move synchronously with the second support 5121, so that the pushing member 5122 keeps away from the first support 5111. And, when the second support 5121 moves away from the first support 5111 to release the reaction cup, the pushing member 5122 can move along with the second support 5121 to approach the first support 5111 synchronously, so that the pushing member 5122 pushes the reaction cup away from the first support 5111.

Wherein, the pushing member 5122 can be integrally formed with the baffle 512; for example, the pushing member 5122 and the baffle 512 may be integrally formed by injection molding, die casting, sheet metal process, CNC (Computernumericalcontro l, numerical control machine) processing, or the like.

Alternatively, the pusher 5122 may be formed separately from the baffle 512. Thus, a suitable pusher 5122 can be selected according to actual demands. For example, the pusher 5122 can be removably mounted to the baffle 512 by a threaded connection, a snap-fit connection, a plug-in connection, or the like. Alternatively, the pusher 5122 may be non-detachably mounted to the baffle 512 by welding, soldering, or the like.

In some embodiments, the first bearing 5111 is provided with a first escape groove 5112 in which the pusher 5122 moves. Further, on the one hand, the probability of interference with the first supporting portion 5111 during the movement of the pushing member 5122 can be reduced; on the other hand, the first avoiding groove 5112 can be used to limit and guide the movement of the pushing member 5122 to a certain extent, so as to avoid that the pushing member 5122 cannot accurately push the reaction cup on the first supporting portion 5111 away.

The above is illustrative of some of the alternative configurations of the pusher 5122 in the embodiments of the present application. In the following, some other optional structures of the embodiments of the present application are further illustrated.

The bracket 511 may also be provided with a stopper 5113. The limiting member 5113 is located at a side of the cup position facing away from the first supporting portion 5111, so as to limit the reaction cup located at the cup position to move along with the second supporting portion 5121.

For example, in the actual operation, after the waste liquid sucking mechanism 400 sucks the waste liquid in the reaction cup at the cup throwing position, the reaction cup may be adsorbed on the second supporting portion 5121 due to static electricity or the like, so that the reaction cup still cannot normally fall into the reaction cup recycling mechanism 300 after the first supporting portion 5111 and the second supporting portion 5121 release the reaction cup.

In addition, in the actual operation process, there may be some annular protrusions at the middle part of the outer side wall of the reaction cup or at the cup opening, so after the first support portion 5111 and the second support portion 5121 release the reaction cup, the annular protrusions of the reaction cup are blocked on the second support portion 5121. It may also be that the clamping force of the first support portion 5111 and the second support portion 5121 on the reaction cup is too large, so that the reaction cup still adheres to the second support portion 5121 after the first support portion 5111 and the second support portion 5121 release the reaction cup. Of course, it is also possible that the two or three factors mentioned above act together to cause the first support 5111 and the second support 5121 to release the reaction cup, and then the reaction cup remains on the second support 5121, so that the reaction cup is well prevented from remaining on the second support 5121 by the limiting member 5113, thereby improving the reliability of the sample analyzer when the reaction cup is recovered.

Wherein, the limiting member 5113 can be integrally formed with the bracket 511; for example, the stopper 5113 and the bracket 511 may be integrally formed by injection molding, die casting, sheet metal process, CNC processing, or the like.

Alternatively, the stopper 5113 may be formed separately from the bracket 511. Thus, a suitable stopper 5113 can be selected according to actual demands. For example, the stopper 5113 can be detachably mounted on the bracket 511 by screwing, clamping, inserting and pulling out connection, or the like. Alternatively, the stopper 5113 may be non-detachably mounted on the bracket 511 by welding, fusing, or the like, which is not limited in the embodiment of the present application.

The baffle 512 is provided with a second avoidance groove 5124, and an opening is formed at one end of the second avoidance groove 5124 facing the first bearing portion 5111, so that the limiting member 5113 can enter or leave the second avoidance groove 5124 from the opening. Further, on the one hand, the probability of interference with the second supporting portion 5121 during the movement of the stopper 5113 can be reduced; on the other hand, the movement of the baffle 512 can be limited and guided to a certain extent by using the cooperation of the second avoidance groove 5124 and the limiting member 5113, so that the accuracy of the movement of the baffle 512 is improved.

In one embodiment, the support 511 is further provided with a first through hole 5114 located at the cup throwing position, and the first through hole 5114 faces the reaction cup recycling mechanism 300. The first supporting portion 5111 is disposed at one side of the hole of the first through hole 5114, and the driving component 52 drives the second supporting portion 5121 to move relative to the first supporting portion 5111, so that the reaction cup at the cup throwing position is clamped in the first through hole 5114 or falls from the first through hole 5114.

That is, the opening degree of the first through hole 5114 can be controlled by driving the movement of the second supporter 5121 by the driving assembly 52. When the first through hole 5114 is opened by the second support 5121 to be smaller, the reaction cup can be clamped at the first through hole 5114, so as to be clamped by the first support 5111 and the second support 5121. When the first through hole 5114 is opened by the second support 5121 to be larger, the cuvette may pass through the first through hole 5114 to fall to the recovery inlet of the cuvette recovery mechanism 300.

It is also understood that the reaction cup at the cup throwing position can be well limited by the hole wall of the first through hole 5114. Furthermore, taking the example that the first support portion 5111 and the second support portion 5121 are disposed at a left-right interval, in the process of clamping the reaction cup by the cooperation of the first support portion 5111 and the second support portion 5121, the reaction cup can be prevented from falling down after being extruded to slide forward or backward, thereby affecting the normal recovery of the reaction cup. Therefore, the embodiment of the application can improve the reliability of the sample analyzer in the process of recycling the reaction cup.

The bracket 511 is further provided with a limiting member 5113, and the limiting member 5113 may be disposed at a side of the opening of the first through hole 5114 away from the first supporting portion 5111.

Of course, in some other embodiments, the bracket 511 may be not provided with the first through hole 5114, which is not limited in this embodiment.

In some embodiments, the bracket 511 is further provided with a guide channel 5115, one end of the guide channel 5115 communicates with the first through hole 5114, and the other end of the guide channel 5115 communicates with the recovery inlet. Thus, the cuvette dropped at the cuvette position can be well guided into the cuvette recycling mechanism 300 through the guide channel 5115, so as to improve the reliability of the sample analyzer according to the embodiment of the present application.

It will be further appreciated that, if the pushing member 5122 is continuously combined with the pushing member 5122, the pushing member 5122 may apply a larger pushing force to the reaction cup at the cup throwing position when the pushing member 5122 is operated at a higher speed, and the guiding channel 5115 can effectively prevent the reaction cup falling from the cup throwing position from being pushed away due to the overlarge force, so that the reaction cup can be ensured to fall into the reaction cup recycling mechanism 300 more accurately.

The above is illustrative of some of the alternative configurations of the support assembly 51 for holding and releasing the reaction cup in the embodiments of the present application. The following description continues with reference to some optional configurations of the drive assembly 52 to further illustrate and explain the cuvette carrier 500 according to the embodiments of the present application.

The drive assembly 52 may include a motor 521 and a linkage 522. The motor 521 is fixedly connected with the bracket 511. The linkage 522 includes oppositely disposed third and fourth ends. The third end is fixedly connected with the output shaft of the motor 521. Wherein the baffle 512 is slidably connected to the bracket 511. The baffle 512 is further provided with a sliding groove 5125, and the sliding groove 5125 is slidably connected to the fourth end of the link 522.

Wherein, the direction of the sliding groove 5125 may be perpendicular to the sliding direction of the baffle 512 with respect to the bracket 511.

Furthermore, when the motor 521 starts to rotate, the output shaft of the motor 521 can drive the connecting rod 522 to rotate, and then the fourth end of the connecting rod 522 slides in the sliding groove 5125 of the baffle 512, so that the motor 521 can drive the baffle 512 to slide in a connecting rod transmission manner, and finally the driving assembly 52 of the embodiment of the present application has the advantages of low cost and high reliability.

Illustratively, the baffle 512 may further include a driving portion 5126 and a sliding portion 5127. The transmission 5126 is located on a first side of the motor 521, the first side being a side of the motor 521 facing away from the cuvette retrieval mechanism 300, such as the first side being an upper side of the motor 521. The transmission portion 5126 is provided with the above-described slide groove 5125. The transmission portion 5126 is further connected to the second support portion 5121. The slide 5127 is located on a second side of the motor 521 that is perpendicular to the first side, such as the front side of the motor 521. The sliding portion 5127 is connected to the transmission portion 5126, and the sliding portion 5127 is slidably connected to the bracket 511.

Alternatively, please continue to refer to fig. 5, fig. 5 is a schematic structural diagram of another driving assembly of the reaction cup bearing mechanism shown in fig. 2. The drive assembly 52 may also include a motor 521, a gear 523 and a rack 524 in place of the motor 521 and the linkage 522 described above. The motor 521 is fixedly connected with the bracket 511. Gear 523 is mounted to the output shaft of motor 521. The rack 524 is fixedly connected with the baffle 512. The rack 524 is meshed with the gear 523. Thus, the motor 521 may drive the movement of the baffle 512 via the gear 523.

Of course, the driving assembly 52 may also drive the baffle 512 to move through a sprocket chain, a synchronous pulley, or the like, which is not limited in the embodiment of the present application.

The above is illustrative of some of the alternative configurations of the support assembly 51 for holding and releasing the reaction cup in the embodiments of the present application.

It will also be appreciated that in some other embodiments the support assembly 51 may also be an absorbent assembly for carrying the reaction cup in the cup position by suction.

For example, the support assembly 51 may be a vacuum suction unit, and the driving assembly 52 may be a pump assembly, so that the vacuum suction unit may be driven to suck the cuvette or release the cuvette.

Alternatively, the supporting component 51 may be an electromagnetic adsorption component, and the driving component 52 is a power supply component, so that the power supply component can supply power to or cut off power from the electromagnetic adsorption component to adsorb or loosen the reaction cup. It will be appreciated that the manner in which the support assembly 51 carries and releases the reaction cup at the cup station can be varied and is not limited in this embodiment.

The foregoing is illustrative of some of the cuvette carrier 500 in the embodiments of the present application. In the following, some other alternative configurations of the sample analyzer will be further illustrated.

With continued reference to fig. 6, fig. 6 is another schematic structural diagram of a sample analyzer according to an embodiment of the present application. The sample analyzer may also include a cuvette supply mechanism 600, a sample mechanism 700, a reagent mechanism 800, and a dispensing mechanism 900. The cuvette supply mechanism 600 is used for providing a cuvette. The sample mechanism 700 is used to carry a sample. The reagent mechanism 800 is for carrying a reagent. The dispensing mechanism 900 is configured to aspirate a target liquid including at least one of a sample carried by the sample mechanism 700 and a reagent carried by the reagent mechanism 800 and discharge the target liquid into a cuvette at a dispensing location. The measurement mechanism 100 is used for measuring the reaction liquid carried by the reaction cup positioned at the measurement position. The dispensing mechanism 200 is also used to dispense cuvettes among the cuvette supply mechanism 600, the dispensing station, and the measuring station.

Then, that is, the embodiment of the present application can uniformly complete the dispatching of the reaction cup between different mechanisms or stations by using one dispatching mechanism 200, and no additional power source is required to drive the bearing assembly 51 to integrally move to other stations to grasp the reaction cup. Compared with the additional power source for driving the supporting component 51 to integrally move to other stations to grasp the reaction cup, the embodiment of the application not only can reduce the integral volume of the sample analyzer, but also can avoid the interference between the supporting component 51 and the dispatching mechanism 200 in the integral movement process, thereby improving the integral reliability of the sample analyzer.

It should be understood that the measuring mechanism 100 may be varied according to actual test requirements, and the technical solutions of the embodiments of the present application will be further explained and described below by taking the measuring mechanism 100 as an example for performing a chemiluminescent assay on a reaction solution.

The sample analyzer may also include a magnetic separation mechanism 1000 and an incubation mechanism 1100. The magnetic separation mechanism 1000 is used for performing magnetic separation cleaning and substrate injection on the reaction liquid carried by the reaction cup. The incubation mechanism 1100 is used to incubate reactants carried by the reaction cup. The dispensing mechanism 200 is used to dispense cuvettes between the cuvette supply mechanism 600, the dispensing station, the magnetic separation mechanism 1000, the incubation mechanism 1100, the measurement station, and the cuvette throwing station.

Specifically, the incubation mechanism 1100 may be provided with an incubation aperture. The incubation hole is used for accommodating the reaction cup so as to incubate the reaction liquid in the accommodated reaction cup. Incubation mechanism 1100 may also be provided with a measurement well in which the measurement site is located. That is, the measurement mechanism 100 is used to perform chemiluminescent measurement on the reaction solution in the cuvette in the measurement well.

For example, one of the test flows of the sample analyzer may be as follows:

in a first step, the dispenser 200 grips a cuvette from the cuvette feeder 600 to a dispensing station.

In a second step, the dispensing mechanism 900 dispenses a sample and a reagent, such as a magnetic bead reagent, into a cuvette at the dispensing location to mix to form a first intermediate reaction solution.

Third, the dispatch mechanism 200 grabs the cuvette carrying the first intermediate reaction liquid from the split injection into the magnetic separation mechanism 1000.

Fourth, the magnetic separation mechanism 1000 performs magnetic separation washing on the reaction cup carrying the first intermediate reaction liquid to separate impurities in the first intermediate reaction liquid, and then injects a substrate into the reaction cup to perform luminescent marking, thereby obtaining a second intermediate reaction liquid.

Fifth, the dispatching mechanism 200 grabs the reaction cup carrying the second intermediate reaction liquid into the incubation mechanism 1100 for incubation to obtain the target reaction liquid.

Sixth, the dispenser 200 grips the cuvette carrying the target reaction solution in the measurement position to perform the chemiluminescent assay.

Seventh, the dispatching mechanism 200 grabs the measured cuvette to the cuvette throwing position for recycling.
