Referring to fig. 1-3, an embodiment of the present invention provides a sample distribution device, including: a sample carrying module 11, a reagent carrying module 12 and a sample transfer module 13;

the sample carrier module 11 is provided with a sample container position for carrying a sample container; the reagent carrying module 12 is provided with a reagent container site for carrying a reagent container; the sample transfer module 13 has a sample suction site 132 for sucking up a sample in a sample container, a reagent suction site 131 for sucking up a reagent in a reagent container, and at least one sample discharge site for discharging a sample and/or a reagent; and at least one of the sample positions is located on the track 3 for transferring the sample and reagent flow to the next device.

The sample distribution device 1 of the embodiment is improved over the existing sample distribution device, and a reagent carrying module 12 is additionally arranged, wherein a reagent container carried on the reagent carrying module 12 can be a container for carrying a reagent, such as a reagent bottle; the sample container carried on the sample carrying module 11 may be a container for carrying a sample, such as a sample tube; namely, the sample distribution device 1 of the present invention can provide a sample and a reagent.

The sample transfer module 13 can suck the sample in the sample container through the sample sucking position 132 and directly transfer the sample to the track 3, and discharge the sample to a reaction cup on the track 3 at the sample discharging position to finish sample distribution, and then transfer the sample to a later reagent distribution and measurement device for measurement through the track 3.

The sample transfer module 13 can also suck the sample in the sample container through the sample sucking position 132, suck the reagent in the reagent container at the reagent sucking position 131, and in the sample distribution device 1, after the sample and the reagent are uniformly mixed by the uniformly mixing module 17 or other modules to obtain a sample uniformly mixed liquid, suck the sample uniformly mixed liquid again and transfer the sample uniformly mixed liquid to the track 3, and discharge the sample uniformly mixed liquid to a reaction cup on the track 3 through the sample discharging position so as to complete reagent distribution, and then transfer the sample uniformly mixed liquid to a following reagent distribution and measurement device for measurement by the track 3. In one embodiment, the sample transfer module 13, after aspirating the sample in the sample container and the reagent in the reagent container, discharges directly into the cuvette at the sample level of the rail 3; or firstly sucking the sample, then discharging the sample into a reaction cup positioned at the sample discharge position of the track 3, and then sucking the reagent and discharging the reagent into the reaction cup positioned at the sample discharge position of the track 3; that is, a mixed solution of a sample and a reagent (sample mixed solution) is formed in a cuvette at the discharge position of the rail 3, and the mixed solution of the sample and the reagent is transferred from the rail 3 to the next device (reagent dispensing and measuring device) to be processed. It is understood that the sample mixture includes a sample mixture.

When aiming at a trace sample, the sample transfer module 13 firstly absorbs a certain amount of sample at the sample absorbing position 132, then absorbs the reagent in the reagent container at the reagent absorbing position 131, and finally simultaneously discharges the reagent into the reaction cup, and the absorbed sample enters the sample transfer module 13 because the reagent is absorbed after the sample is absorbed, namely, the sample cannot generate the problem of hanging liquid at the tip of the sample transfer module 13, so that inaccurate sample quantity is avoided, and the accuracy of a subsequent test result is influenced.

Thus, based on the additionally arranged reagent carrying module 12, a part of reagent can be transferred to the sample distribution device 1 for addition, and meanwhile, the other part of reagent is still added by the reagent distribution and measurement device, so that the reagent distribution times of the following reagent distribution and measurement devices are effectively reduced, the detection speed of each reagent distribution and measurement node is improved, and the overall detection efficiency is improved. In addition, the accuracy of the amount of the micro sample to be added can be ensured.

Referring to fig. 1 and 2, in an embodiment, the drain may include a first drain 134 and a second drain 135.

The first sample discharging position 134 is located on the track 3, a plurality of first reaction cup positions 31 for bearing reaction cups are arranged on the track 3, the reaction cups can move from the first reaction cup positions 31 to the first sample discharging position 134 along the track 3, and the sample transferring module 13 discharges samples or sample mixed liquid into the reaction cups of the first reaction cup positions 31 at the first sample discharging position 134.

The second sample discharge position 135 is located inside the sample distribution device 1, and a second cuvette position for carrying a cuvette is provided inside the sample distribution device 1, and the sample transfer module 13 discharges the sample and the reagent into the cuvette at the second cuvette position at the second sample discharge position 135. It will be appreciated that the sample transfer module 13, after the first sample discharge 134 discharges the sample or sample mixture into the cuvette, the track 3 transfers the cuvette carrying the sample or sample mixture to the next device for subsequent testing, i.e. to the reagent dispensing and measuring device for subsequent testing. After the sample and the reagent are discharged from the sample transfer module 13 to the reaction cup at the second reaction cup position at the second sample discharge position 135, the reaction cup carrying the sample and the reagent still carries out the next circulation in the sample distribution device 1, for example, in this embodiment, the sample and the reagent are uniformly mixed, after the mixing is completed, the mixed sample mixture is transferred to the reaction cup at the first sample discharge position 134 on the track 3 by the sample transfer module 13, and finally, the reaction cup carrying the sample mixture is transferred to the next device by the track 3 for the subsequent detection, that is, the reaction cup is circulated to the reagent distribution and measurement device for the subsequent detection.

Based on the first and second sample positions 134 and 135 of the present embodiment, the following dispensing processing manner for the sample and the reagent is formed:

the first allocation processing mode is as follows:

when the test item does not require sample dilution, the sample transfer module 13 sucks the sample on the sample carrying module 11 through the sample sucking position 132 and then directly discharges the sample onto the first sample discharging position 134 on the track 3 (i.e. into the cuvette of the first cuvette position 31), and the cuvette load sample is transported along the track 3 to the subsequent reagent distributing and measuring device for subsequent measurement, while the next cuvette is transported to the first sample discharging position 134. Since a sample may correspond to a plurality of test items, the present embodiment may be performed in a one-suction multi-row manner, and the sample transfer module 13 suctions a sample and then sorts the sample into each reaction cup located at the first sample placement position 134 on the track 3.

The second allocation processing mode is as follows:

when the test item needs sample dilution, the sample transfer module 13 moves to the sample sucking position 132 and sucks a certain amount of sample in the sample container, then the sample is discharged to a reaction cup on the second reaction cup position through the second sample discharging position 135, then the sample transfer module 13 moves to the cleaning position 133, the sucking needle of the sample transfer module 13 is cleaned through the cleaning module 14 in the sample distribution device 1, after cleaning is finished, the sample transfer module 13 moves to the reagent sucking position 131 and sucks a certain amount of reagent in the reagent container, and then the reagent is discharged to the reaction cup on the second reaction cup position; thus, the reaction cup on the second reaction cup position is loaded with a sample and a reagent; then, the cuvette gripping module 20 in the sample distribution device 1 is used for gripping the cuvette loaded with the sample and the reagent on the second cuvette position, transferring the cuvette to the mixing module 17 in the sample distribution device 1 for shaking and mixing, and after mixing, gripping the cuvette back to the second cuvette position for performing the cuvette separation treatment or transferring the cuvette to the first cuvette position 31. In the second dispensing method, when the test item needs to be diluted, the sample transfer module 13 may be moved to the reagent sucking position 131, a certain amount of reagent in the reagent container is sucked, then transferred to the sample sucking position 132, a certain amount of sample in the sample container is sucked, finally discharged into a reaction cup located at the second reaction cup position, and after the discharge is completed, the sample transfer module 13 is transferred to the cleaning position 133, and the sample transfer module 13 is cleaned by the cleaning module 14. The advantage of doing so is, firstly absorb reagent, then absorb the sample, when guaranteeing that the reagent in the reagent container can not be polluted, also reduced the use amount of washing liquid, improved the transfer efficiency of sample transfer module 13, further improved the detection efficiency of sample.

The method for grabbing the uniformly mixed reaction cup and returning the reaction cup to the second reaction cup position for cup separation treatment comprises the following steps: assuming that the sample to be diluted is divided into 10 parts, the sample transfer module 13 sucks the sample mixed solution of the reaction cups, and then discharges the sample mixed solution into 10 reaction cups positioned on the track 3; the diluted cuvette is discarded by the cuvette handling module 20 in the sample distribution device 1 to the recovery module 15. Alternatively, the sample transfer module 13 sucks the sample mixture of the cuvette, then discharges the sample mixture to 9 cuvettes positioned on the track 3, and the diluted cuvette is transferred to the first cuvette position 31 of the track 3 by the cuvette gripping module 20.

It can be understood that if multiple tests are required for the same sample or multiple diluted sample solutions are required to be divided, the sample transfer module 13 can transfer the samples in a manner of one sucking multiple rows, that is, sucking the samples once and discharging the samples into the reaction cups on the track 3 in multiple times, so as to improve the transfer efficiency of the sample transfer module 13, and meanwhile, reduce the turnover time of the samples or the sample solutions on the sample distribution device 1 and improve the detection efficiency of the samples.

In one embodiment, the structure of the sample carrier module 11 is designed based on the second distribution processing manner.

In a first structural design of the sample carrier module 11, the sample carrier module 11 may comprise a drive assembly and a sample carrier assembly; the sample container position and the second cuvette position are disposed on the sample carrier assembly, and the driving assembly is used for driving the sample carrier assembly to move so that the sample container position or the second cuvette position moves to the sample sucking position 132. Referring specifically to the sample carrier module 11 shown in fig. 4, the sample carrier assembly has 4 sample container positions, respectively 1, 2, 3, and 4 positions, and 2 second cuvette positions, respectively 5 and 6 positions. When the second dispensing mode of sample is performed by the structural design, the driving component drives the sample carrying component to move and the sample container position to the sample sucking position 132 so that the sample transferring module 13 firstly sucks the sample, and then the driving component drives the carrying component to move and switch to the second reaction cup position to move to the sample sucking position 132 so that the sample transferring module 13 discharges the sample into the reaction cup on the second reaction cup position, that is, the sample transferring module 13 does not need to move when discharging the sample to the second reaction cup position through the second discharge position 135, that is, the sample sucking position 132 and the second discharge position 135 are the same position in the structure.

In one embodiment, the reagent sucking site 131 is located at one end of the movement track of the sample transfer module 13, and the first sample discharging site 134 is located at the other end of the movement track of the sample transfer module 13. The reagent sucking position 131 and the first sample discharging position 134 are respectively positioned at the edges of the movement track of the sample transferring module 13. The reason for this arrangement is: in the sample dispensing device 1, the number of the sites where the reagent is required to be used is small relative to the sites where the sample is sucked, and therefore the reagent sucking site 131 is placed at the extreme edge of the movement locus of the sample transfer module 13; in addition, the first sample placement 134 is located on the track 3, where the track 3 needs to be connected to the sample distribution device 1 and the reagent distribution and measurement device, and the track 3 is generally independent from the sample distribution device 1 and the sample distribution and measurement device, that is, the track 3 is located outside the sample distribution device 1 and the sample distribution and measurement device, so that the first sample placement 134 is placed on the other edge of the movement track of the sample transfer module 13. In a preferred embodiment, the reagent sucking site 131, the sample sucking site 132, the washing site 133 and the first sample discharging site 134 are arranged in this order along the movement locus of the sample transfer module 13 (refer to the arcuate dashed line locus in fig. 1). The reason for this arrangement is: in the sample dispensing device 1, the number of the sites where the reagent is required to be used is small relative to the sites where the sample is sucked, and therefore the reagent sucking site 131 is placed at the extreme edge of the movement locus of the sample transfer module 13; the reason why the cleaning position 133 is located in the middle of the sample sucking position 132 and the first sample discharging position 134 is because the first sample discharging position 134 is located on the rail 3, the cleaning position 133 cannot be disposed outside the apparatus, and if disposed in the middle of the sample sucking position 132 and the reagent sucking position 131, the reagent sucking scene is small, and if disposed therebetween, the movement distance of the sample transferring module 13 is increased or caused, which is unfavorable for improving the operation efficiency of the apparatus.

In the structural design of the second sample carrying module 11, the sample container position on the sample carrying module 11 is separately set from the position of the second cuvette position, only the sample container position is arranged on the sample carrying module 11, and the second cuvette carrying module 16 (as shown in fig. 2) is separately arranged, that is, two separate modules are arranged and separately driven by two independent driving components to move, and the second cuvette position is arranged on the second cuvette carrying module 16. When the second sample distribution processing mode is performed through the structural design, the corresponding driving component drives the sample bearing component to move and enables the sample container to move to the sample sucking position 132, so that the sample transferring module 13 firstly sucks the sample; the corresponding drive assembly then drives the second cuvette carrier module 16 to move and move the second cuvette position onto the second row of sample positions 135 of the sample transfer module 13; then the sample transfer module 13 moves to the second sample discharge position 135 along the movement track and discharges the sample into the cuvette at the second cuvette position, that is, the second sample discharge position 135 in this structure only needs to be on the movement track of the sample transfer module 13. Namely, the reagent sucking position 131, the sample sucking position 132, the second sample discharging position 135, the washing position 133 and the first sample discharging position 134 are arranged in this order along the movement locus of the sample transfer module 13 (refer to the arc-shaped dotted line locus in fig. 2).

It can be understood that based on the arc track of the sample transfer module 13, the sample transfer module 13 is a rocker arm needle mechanism and has the advantages of simple control and high efficiency. Of course, the sample transfer module 13 may also adopt a three-dimensional motion mechanism, that is, may move in a certain area, so that the positions of the reagent sucking position 131, the sample sucking position 132 and the sample discharging position may be dynamically changed and adjusted; the above schemes can well distribute samples and reagents.

The sample distribution device 1 of the present invention is described in more detail below:

in one embodiment, the sample distribution device 1 further comprises: a cuvette sequencing module and a cuvette grasping module 20; the cuvette sequencing module comprises a cuvette loading module 18 and a cache disc module 19.

The cuvette loading module 18 is configured to provide empty cuvettes and transfer the cuvettes to the buffer tray module 19 one by one for storage, and the cuvette grabbing module 20 is configured to grab the empty cuvettes from the buffer tray module 19 and transfer the empty cuvettes to the first cuvette position 31 and the second cuvette position.

The cuvette grabbing module 20 is further configured to transfer a cuvette (a cuvette having a sample and a reagent) at a second cuvette position to the mixing module 17 for mixing, and transfer a cuvette having a sample mixed solution from the mixing module 17 to the first cuvette position 31 or the second cuvette position after mixing, so as to complete a transfer process of mixing. Furthermore, the cuvette grabbing module 20 may further have a mixing function, that is, after the cuvette grabbing module 20 grabs a cuvette filled with a sample and a reagent, the cuvette grabbing module directly performs a mixing operation on the gripper, so that the mixing module 17 may not be required to be separately arranged, and the cuvette may be placed at the second cuvette position or the first cuvette position 31 as required after the mixing is completed.

In one embodiment, the sample distribution device 1 further comprises: the device comprises a manipulator module 21, a cover opening module 24, a sample injection module 22 and a recovery channel 23.

The sample container and the reagent container can be loaded on the tray in batches in advance, the tray is put into the putting-in area 221 of the sample-in module 22 for sample injection, and the sample is injected to the designated position 222 in a belt transmission or pushing mode; the manipulator module 21 grabs the sample container and the reagent container from the appointed position 222, respectively transfers the sample container and the reagent container to the cover opening module 24 for cover opening, and continues to transfer to the sample container position and the reagent container position after the cover opening; the empty tray after gripping the reagent vessel is transferred to the recovery area 231 of the recovery channel 23 by means of belt transfer or pushing in the recovery channel 23. A tray for loading sample containers, the standby manipulator module 21 transfers the sample containers to the sample carrier module 11, the sample transfer module 13 suctions the samples in the sample containers, and the manipulator module 21 transfers the sample containers to the sample container tray. After the sample containers on the same sample container-loading tray have all been sucked up at the sample-carrying module 11 and have all been transferred back onto the tray, the sample container-loading tray is transferred to the recovery section 231 of the recovery channel 23 by means of belt conveyance or pushing at the recovery channel 23. The cover opening module 24 comprises a first clamping component, the first clamping component is used for clamping and fixing the body of the sample container and/or the reagent container, when the sample container or the reagent container needs to be subjected to cover opening treatment, the manipulator module 21 grabs the sample container or the reagent container onto the cover opening module 24, the body of the sample container or the reagent container is clamped and fixed by the first clamping component, then the manipulator module 21 clamps the container cover of the sample container or the reagent container and drives the container cover to move upwards relative to the first clamping component, so that the container cover is separated from the body of the sample container or the reagent container, and cover opening is realized. In one embodiment, the manipulator module 21 is the same for holding the sample container, the reagent container, and the cover opening process, thereby improving the utilization efficiency of the manipulator and simplifying the structure of the sample dispensing apparatus 1.

It will be appreciated that the sample containers and the reagent containers may be fed in the same manner and may be fed to the designated location 222 by the same set of feeding means, and in this embodiment, there may be a plurality of designated locations 222, for example, the sample container has one designated location 222 and the reagent container has one designated location 222, in this embodiment, the designated location 222 is one, that is, the sample container and the reagent container are both transferred to one location.

In another embodiment of the designated location 222, the designated location 222 may be the sample suction location 132, i.e., the sample container function of the integrated sample carrier module 11; or the reagent sucking position 131, that is, the function of a reagent container of the reagent carrying module 12 is integrated; in the case of the sample suction position 132, the reagent container must be transferred to the reagent loading module by the manipulator module 21 when transferred to this position, and similarly, in the case of the sample suction position 131, the sample tube must be transferred to the sample suction position 132 by the manipulator module 21.

In another embodiment of the designated position 222, the designated position 222 refers to a gripping position of the manipulator module 21 for gripping a sample container or a reagent container to the uncapping module 24 (if the reagent container or the sample container is already manually uncapped by a user in line, the uncapping process is not required), and the uncapping process is: the clamping assembly of the cover opening module 24 clamps the sample container or the reagent container, the manipulator module 21 can realize the cover opening operation of the reagent container or the sample container by upward linear motion or rotary motion, and in the cover opening process, the aerosol removing device on the cover opening module 24 is opened to suck aerosol generated in the cover opening process, so as to prevent biological pollution; after the cover is opened, the waste cover is discarded into the recovery module 15 by the manipulator module 21; the uncapped sample container or reagent container is then transferred to the sample carrying module 11 or the reagent carrying module 12, and the sample transfer module 13 is used for sucking the sample or reagent.

In one embodiment, the sample dispensing device 1 further comprises a code scanning module 25.

The code scanning module 25 is located at one side of the sample carrying module 11, and the code scanning module 25 is used for identifying a bar code on a sample container to obtain sample information; to facilitate identification by the code scanning module 25, the sample carrier module 11 further includes a rotation assembly for driving the sample container to rotate so as to rotate the sample container, thereby enabling the code scanning module 25 to scan the bar code on the sample container.
