Description

Automatic sample introduction system, sample analysis system and automatic sample introduction control method

Technical Field

The invention relates to an automatic sample introduction system, a sample analysis system and an automatic sample introduction control method.

Background

Analytical devices, such as biochemical analyzers, immunological analyzers, cellular analyzers, and the like, are instruments for analyzing and measuring samples, and generally measure chemical components, concentrations, and the like in a sample by adding a reagent to the sample and subjecting the sample after reaction with the reagent to a certain manner.

The mechanism for supplying a sample to an analysis apparatus roughly includes three types. The first is to set a fixed sample position in the analysis device. When the sample needs to be rechecked, the sample is directly re-absorbed into the fixed sample position for rechecking, and the requirement of sample rechecking priority treatment can be met; this type of sample supply mechanism is not suitable for large batch sample testing. The second way of supplying samples is to provide a sample backup in the analysis device, and when the samples need to be retested, the samples are sucked from the sample backup for retesting, and this type of mechanism is also not suitable for large-batch sample testing. The third sample supply mode is to arrange a sample scheduling system independent of the analysis equipment, can flexibly design systems with different scheduling capabilities according to the number of samples, and can adapt to large-batch sample testing. However, the current sample scheduling system generally has the problems that the reinspection and emergency treatment samples need to be scheduled to the placement area for queuing, so that the test result output efficiency of the reinspection and emergency treatment samples is low, and the requirements of prior processing of the current reinspection and emergency treatment requirements cannot be met.

Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.

The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings). In addition, the directions of up, down, left, and right referred to herein are referred to the paper direction of the drawings.

Referring to fig. 1 and 2, an automatic sample feeding device disclosed in some embodiments of the present application includes a feeding channel 10, a loading area 20, a buffer area 30, an emergency area 40, and a transit scheduling mechanism 50. It should be noted that some embodiments of the autosampler device may not include an emergency zone 40, such as is illustrated in fig. 1, and some embodiments of the autosampler device may include an emergency zone 40, such as is illustrated in fig. 2. The following specifically describes each part of the automatic sample introduction device.

The feed channel 10 is where the analysis device sucks in the sample. In some embodiments, the feed channel 10 is disposed in a first direction, such as the X-axis direction in fig. 1 and 2. The feed channel 10 is used to carry a sample rack and to move the sample rack along its length over the feed channel. As shown in fig. 3, the sample rack has a length, a width and a height of L, W and H, respectively, and the sample rack has a length direction, i.e., a measuring direction of the length L, and a height direction, i.e., a measuring direction of the height H. In some embodiments, the feeding channel 10 is further provided with a sample sucking position, such as the sample sucking position 10a in fig. 1 and 2, for sucking the sample on the sample rack when the sample on the sample rack is located at the sample sucking position of the feeding channel 10; in other words, when the sample on the sample rack is located at the suction position of the feeding channel 10, the analysis device sucks the sample, and the sample rack can be continuously moved along the first direction, so that the samples carried by the sample rack pass through the suction position one by one, and all the samples of the sample rack are sucked by the analysis device respectively.

Referring to fig. 4, in order to make the sample rack reciprocate on the feeding path 10, i.e. move in the same direction as the first direction (e.g. positive X-axis direction in the figure) and in the opposite direction (e.g. negative X-axis direction in the figure), or in the left and right directions in the figure, a reciprocating feeding mechanism 11 may be provided on the feeding path 10. By arranging the reciprocating feeding mechanism 11 on the feeding channel 10 and carrying the sample rack on one track in a bidirectional way, the sample sucking of the primary detection sample, the secondary detection sample and the emergency treatment sample can be completed by one feeding channel, the priority treatment of the secondary detection sample and the emergency treatment sample can be realized, and the defect that the queue waiting is needed for the secondary detection sample and the emergency treatment sample in the prior art is overcome. In one embodiment, referring to fig. 5, the reciprocating feeding mechanism 11 includes a motor 11a and a locking portion 11 b. The bottom of the sample holder is provided with a plurality of grooves 11 c. The clamping part 11b can be driven by the motor 11a to extend and contract along the height direction of the sample rack and move towards the same direction and the opposite direction of the first direction; when the blocking part 11b is driven to extend out, the blocking part can be matched with any one of the grooves of the sample rack, so that when the blocking part 11b is driven, the sample rack is driven to move together in the same direction and the opposite direction to the first direction, for example, when the blocking part 11b is driven to move in the first direction, the sample rack can be driven to move together in the first direction, and when the blocking part 11b is driven to move in the opposite direction to the first direction, the sample rack can be driven to move together in the opposite direction to the first direction.

Other components may also be provided on the feed channel 10, such as at least one of a test tube/cap presence detection mechanism 12, a test tube rotation mechanism 13, and a scanner 14. The scanner 14 is used to scan the labels of the test tubes to obtain sample information. The test tube rotation mechanism 13 is used to drive the test tube rotation mechanism, for example, when the sample rack moves on the feeding path 10, if the scanner 14 cannot scan the test tube carried on the sample rack, which may be because the side of the test tube with the label is not facing the scanner 14, the test tube rotation mechanism 13 drives the test tube rotation at this time, so that the label of the test tube is aligned with the scanner 14. The test tube/test tube cap presence or absence detecting mechanism 12 is used for detecting whether the test tube is present or not and whether the test tube cap on the test tube is present or not, and if the test tube or the test tube cap presence or absence detecting mechanism detects that the sample position on the sample rack is not provided with the test tube or the like, the automatic sample feeding device can give an alarm.

The above are some illustrations of the feed channel 10.

The loading area 20 is communicated with the feeding channel 10 and is used for carrying the sample rack with the length direction along the first direction, and the sample rack moves to the sample sucking position along the first direction after moving to the feeding channel 10 along the second direction. In some embodiments herein, the first direction and the second direction are perpendicular, for example, the X-axis direction is the first direction and the Y-axis direction is the second direction. The loading area 20 may be used for a user to place a batch of sample racks carrying samples to be tested.

The buffer area 30 is used for carrying sample racks waiting for test results after sample suction and/or sample racks storing emergency samples. In some embodiments, the buffer 30 carries the sample racks, and the length of the sample racks is parallel to the first direction, and the sample racks are moved out of the buffer 30 in the same or opposite direction as the first direction, and the sample racks are moved into the buffer 30 in the same or opposite direction as the first direction. In a specific embodiment, referring to fig. 6, the buffer area 30 includes a plurality of buffer bits 31 sequentially arranged along the second direction; any one of the buffer bits 31 can carry a sample rack with a length direction parallel to the first direction, and allow the sample rack to move out of the buffer 30 in the same or opposite direction as the first direction, and allow the sample rack to move into the buffer 30 in the opposite or same direction as the first direction. In the example of fig. 1 and 2, the sample rack is moved out of the buffer 30 in a first direction and into the buffer in a direction opposite to the first direction.

In order to enable each sample rack to be stably placed in the buffer area, in some embodiments, referring to fig. 7, the buffer area 30 includes a baffle 31a and a plurality of partition plates 31b, an arrangement direction of the plurality of partition plates 31b is parallel to the first direction, the plurality of partition plates 31b are arranged at intervals and are arranged along the second direction, and a buffer position 31 is formed between two adjacent partition plates 31 b; the baffle 31a is disposed in a direction parallel to the second direction, and the baffle 31a is connected to one end of the plurality of partitions 31 b.

In the case that the total number of cache bits in the buffer 30 is substantially constant, in some embodiments, the number of the buffer 30 may be one, as is the case in fig. 1 and 2, for example. In some embodiments, the number of the buffers 30 is at least two, for example, two or more, and the total buffer bits are distributed into two or more buffers 30 to realize the design size change in a certain dimension. In some embodiments, when there are multiple buffers 30, these buffers are arranged in parallel. In some embodiments, when there are multiple buffers 30, the buffers are arranged in parallel in a first direction. The buffers are arranged in parallel along a first direction, for example, fig. 8 is an example, and it can be seen that, although the length of the automatic sample feeding device in the first direction is increased, the automatic sample feeding device can be arranged at one side of the analysis equipment subsequently, and the first direction is consistent with the length direction of the analysis equipment, so that in practical situations, the length of the automatic analysis device in the first direction has sufficient design space; in addition, the length of the buffer areas in the second direction can be reduced by arranging the buffer areas in parallel along the first direction, and the design space in the second direction is relatively small, so that the length of the automatic analysis device in the second direction is expected to be reduced as much as possible in practical situations. After the automatic feeding device is arranged in this way, when the automatic feeding device is assembled with the analysis equipment, as described above, the automatic feeding device is arranged on one side of the analysis equipment, and the first direction is consistent with the length direction of the analysis equipment, so that the length direction (i.e. the length in the first direction) of the final complete machine can be kept unchanged, and the longitudinal depth (i.e. the length in the second direction) can not be increased by a large amount due to the addition of the automatic feeding device. In addition, for the buffer 30 on the left in fig. 8, the sample rack can be moved into the buffer 30 in a first direction and out of the buffer in a direction opposite to the first direction; for the buffer 30 on the right in fig. 8, the sample rack can then be moved out of the buffer in a first direction and into the buffer in a direction opposite to the first direction.

It is not limited to two buffer areas 30 as an example, in some embodiments, the two buffer areas 30 are separated by a middle area 32, and the two buffer areas 30 are disposed in axial symmetry with the middle area 32 as an axis of symmetry. The length of the intermediate zone 32 in the first direction is at least the length of the sample rack, so that the sample racks in the two buffer zones 30 can be moved completely into the intermediate zone 32 in the same or opposite direction as the first direction. The sample holder may then be moved in the same or opposite direction as the second direction. Also taking fig. 8 as an example, for the left buffer 30 in fig. 8, the sample rack can be moved out of the buffer in a direction opposite to the first direction and into the middle zone, and can be moved from the middle zone into the buffer in the same direction as the first direction; for the buffer zone 30 on the right in fig. 8, the sample rack can then be moved out of the buffer zone in a first direction and into the middle zone, and can be moved from the middle zone into the buffer zone in a direction opposite to the first direction. The transfer schedule 50 moves back and forth in the intermediate section 32. The transfer scheduling mechanism 50 moves in a direction opposite to the second direction to schedule the sample rack coming out of the feeding path 10 into the corresponding buffer bit 31 of the buffer 30; the transfer scheduling mechanism 50 moves in the same direction as the second direction to fetch and schedule the samples in the corresponding buffer bits 31 of the buffer 30 into the feed channel 10 for re-sampling.

In some embodiments, the loading area 20 and the buffer area 30 are on the same side of the feed path 10, such as below the feed path 10 in the figures.

The above is some of the description of the buffer 30.

The emergency area 40 is used for a user to place a sample rack — for example, the user can place a sample rack carrying emergency samples into the emergency area 40. In some embodiments, the emergency area 40 is connected to at least one of the cache areas 30 — when there are more than one cache area 30, the emergency area 40 is in communication with at least one of the cache areas 30. The emergency area 40 is used for moving the sample rack from the emergency area 40 to the buffer area 30 in communication with the emergency area 40. In some embodiments, the emergency area 40 carries a sample rack that is disposed lengthwise in a first direction, and the sample rack is moved from the emergency area 40 to the buffer area 30 in communication in a direction that is the same as or opposite to the first direction. In some embodiments, emergency zone 40 includes at least one emergency location 41; the emergency treatment position 41 is aligned with the buffer position 31 of the buffer area 30, and is used for carrying the sample rack placed along the first direction along the length direction, and enabling the sample rack to move out of the emergency treatment position 41 and enter the buffer position 31 aligned with the emergency treatment position 41 along the same direction or the opposite direction of the first direction. Fig. 6 and 8 illustrate two examples, and the sample racks in the emergency area 40 may be moved in a first direction from the emergency area 40 into the associated buffer area 30, for example, from the emergency position 41 into the buffer position 31 aligned with the emergency position 41 in the first direction. As mentioned above, in some embodiments, the buffer area 30 includes the baffle 31a and the partition 31b, it is understood that when the autosampler has the emergency area 40, the partition 31b does not separate the emergency area 40 from the buffer area 30, i.e. the partition 31b does not prevent the sample rack from entering the buffer area 30 communicated with the emergency area 40, for example, the partition 31b is not disposed at the buffer position 31 communicated with the emergency position 41.

In some embodiments, the emergency area 40 may also be disposed in the cache area 30. In some embodiments, the buffer bits 31 of at least one buffer area 30 are set as emergency treatment bits for the user to place the sample rack.

In some embodiments, the emergency area 40 is provided with a button (not shown), which when triggered generates an instruction for testing the sample rack in the emergency area 40, i.e. an emergency instruction.

The above are some of the descriptions regarding emergency zone 40.

The relay dispatching mechanism 50 is used to dispatch the sample rack between the buffer 30 and the feed channel 10. In some embodiments, the transfer scheduling mechanism 50 moves the sample rack with the sample sucking completed out of the feeding channel 10 into the buffer 30 to wait for the test result, and moves the corresponding sample rack in the buffer 30 out of the buffer 30 and into the feeding channel 10 when the test result of the sample indicates that the sample needs to be retested. In some embodiments, when an emergency instruction input by a user is received, the sample rack corresponding to the emergency instruction in the buffer 30 is removed from the buffer 30 and moved into the feeding channel 10.

In some embodiments, the sample aspirating position of the feed channel 10 is located between the loading zone 20 and the buffer zone 30; the sample rack moved into the feed path 10 from the loading area 20 is moved to the suction position in a first direction, and the sample rack taken out of the buffer area 30 and moved into the feed path 10 by the transfer scheduling mechanism 50 is moved to the suction position in a direction opposite to the first direction, for example, by the reciprocating feed mechanism 11 of the feed path 10, the sample rack moved into the feed path 10 from the loading area 20 is driven to be moved to the suction position in the first direction, and the sample rack taken out of the buffer area 30 and moved into the feed path 10 by the transfer scheduling mechanism 50 is driven to be moved to the suction position in a direction opposite to the first direction. In some embodiments, referring to fig. 9, the feeding channel 10 includes a first channel opening 10b and a second channel opening 10c, the loading area 20 is located at one end of the first channel opening 10b of the feeding channel, and the buffer area 30 is located at one end of the second channel opening 10c of the feeding channel 10, so that the loading area 20 moves the sample rack from the first channel opening 10b into the feeding channel 10, and the transfer scheduling mechanism 50 moves the sample rack from the buffer area 30 and from the second channel opening 10c into the feeding channel 10. In particular embodiments, the transfer scheduling mechanism 50 is configured to move the sample rack in at least a second direction to enable the sample rack to be moved to the feed channel 10 after being removed from the buffer zone 30, and to remove the sample rack in at least a direction opposite to the second direction to enable the sample rack to be moved to the buffer zone 30 after being removed from the feed channel 10. It can be seen that, in the present application, by redesigning the arrangement, function and sample rack in-and-out path among the feeding channel 10, the loading area 20 and the buffer area 30, the normal sample to be tested enters the feeding channel 10 from the loading area 20, and moves to the sample sucking position along the first direction to complete sample sucking; the sample needing the re-examination and the emergency treatment can enter the feeding channel 10 from the buffer area 30 and move to the sample sucking position along the direction opposite to the first direction for sample sucking, so the sample needing the re-examination and the emergency treatment passes through a path which is completely different from the normal sample to be tested and enters the sample sucking position, the sample needing the re-examination and the emergency treatment can be preferentially processed, the problem that other normal samples to be tested exist on the path which the sample needs to enter the sample sucking position to wait for the sample to be tested to enter does not exist, and the problems of elimination and queue insertion together with the normal samples to be tested do not exist.

There are various implementations of the transfer scheduling mechanism 50. For example, in some embodiments, referring to fig. 10, the transfer scheduling mechanism 50 includes a motor 51 and a rack bracket 52; the test tube rack bracket 52 is used for bearing a sample rack with the length direction along the first direction; the motor 51 is capable of driving the rack brackets 52 to move in the same direction as the second direction and in the opposite direction, so as to drive the sample racks carried by the rack brackets 52 to move together in the same direction as the second direction and in the opposite direction. In some embodiments, the transfer scheduling mechanism 50 further includes a rack transfer mechanism 53, and the rack transfer mechanism 53 is configured to move a sample rack having a length direction along a first direction into or out of the rack brackets 52 along the same direction or along a direction opposite to the first direction. In some embodiments, the transfer scheduling mechanism 50 further includes a first test tube rack presence or absence 54 and/or a second test tube rack presence or absence 55. The first test mechanism 54 is used for testing whether the rack bracket 52 carries a sample rack. The second test mechanism 55 for detecting whether the buffer position aligned with the rack bracket 52 carries a sample rack or not is used for detecting whether the sample rack is carried by the rack.

The above are some of the descriptions regarding the transit scheduling mechanism 50.

Referring to fig. 11, the automatic sample introduction device of some embodiments of the present application further includes an unloading channel 60 and an unloading area 70.

The discharge passage 60 is arranged in a first direction for carrying the sample rack lengthwise in the first direction and for moving the sample rack from the discharge passage 60 into the discharge area 70 in a direction opposite to a second direction. In some embodiments, the discharge passage 60 is aligned with the feed passage 10. Specifically, in some embodiments, the transfer scheduling mechanism 50 is configured to move the sample rack, which has the detection result indicating that the sample does not need to be retested, in the buffer area 30 at least in the second direction, so that the sample rack can be moved into the unloading channel 60 after being removed from the buffer area 30.

The unloading zone 70 is used for carrying the sample rack with the length direction along the first direction and moving the sample rack along the direction opposite to the second direction. In some examples, the user may remove a sample rack from the unloading area 70 that has been tested or is to be retrieved.

It can be seen that the sample rack carrying the sample to be tested enters the feeding channel 10 from the loading area 20, and does not need to be scheduled by the transfer scheduling mechanism 50; the transfer scheduling mechanism 50 is mainly used for scheduling the sample rack carrying the reinspection sample and the sample rack carrying the emergency sample in the buffer area 30 to the feeding channel 10, and scheduling the sample rack which is completely tested or to be recovered to the unloading channel 60; functionally, the sample suction scheduling of the sample entering the system for the first time and needing to be tested is separated from the scheduling of special functions, namely the scheduling of emergency treatment, the scheduling of reexamination and the scheduling of unloading, the sample suction scheduling is realized through the loading area 20 and relevant mechanisms on the feeding channel 10, the scheduling of emergency treatment, the scheduling of reexamination and the scheduling of unloading are realized by the transfer scheduling mechanism 50, the labor division is clear, and the efficiency of matching, processing and realizing the scheduling process in the whole testing process is high.

In some embodiments, the unloading area 70, the buffer area 30, and the loading area 20 are located on the same side of the feeding path 10, such as below the feeding path 10. In some embodiments, the loading area 20, the buffer area 30, and the unloading area 70 are sequentially disposed along the first direction.

The above is a description of the autosampler device of some embodiments of the present application.

The autosampler is used to supply the analytical equipment with sample racks carrying samples. Referring to fig. 12, in some embodiments of the present application, a sample analysis system is disclosed, which includes an automatic sample introduction device 1 and an analysis apparatus 2, where the automatic sample introduction device 1 may be the automatic sample introduction device disclosed in any embodiment of the present application, and the analysis apparatus 2 is configured to suck a sample from a sample rack provided by the automatic sample introduction device 1 and analyze the sample. The automatic sample feeding device 1 is arranged on one side of the analysis equipment 2, and the first direction is consistent with the length direction of the analysis equipment 2. After the arrangement, the length direction (namely the length in the first direction) of the final complete machine can be kept unchanged, and the longitudinal depth (namely the length in the second direction) cannot be increased by a large amount due to the addition of the automatic sampling device, so that the final complete machine is very favorable for being placed in a room for arrangement, and the space of a department is effectively utilized. Specifically, the loading area 20 and the buffer area 30 are located on a first side of the feeding channel 10, for example, below in the figure, and when the automatic sample feeding device 1 further includes the unloading area 70, the loading area 20, the buffer area 30 and the unloading area 70 are located on the first side of the feeding channel 10, for example, below in the figure; the analysis device 2 is located at a second side of the autoinjector 1 opposite the first side, e.g. above in the figure.

The flow of how the autosampler supplies sample holders to the analyzer is described below.

The description is not limited to fig. 8, 11, or 12, where the first direction is a positive X-axis direction, the opposite direction is a negative X-axis direction, the second direction is a positive Y-axis direction, and the opposite direction is a negative Y-axis direction.

The sample rack carrying the sample to be tested in the loading zone 20, is moved in a second direction into the feed channel 10, then moving in a first direction on the feed channel 10 to pass the sample aspirating position, the analyzing device aspirating the sample at the aspirating position, after all the samples on the sample rack have been aspirated, the sample rack continues to enter the transfer scheduling mechanism 50 along the first direction from the feeding channel 10, and after the transfer scheduling mechanism receives the sample rack, the transfer scheduling mechanism drives the sample rack to move in the direction opposite to the second direction, and then stalls in line with an empty buffer bit 31-if the empty buffer bit 31 is in the left buffer 30 in the figure, the sample rack moves in the first direction to enter the left buffer 30, if the empty buffer bit 31 is in the buffer 30 on the right in the figure, the sample holder is moved in the opposite direction to the first direction to enter the buffer 30 on the right. The purpose of the sample rack entering the buffer 30 is to wait for the results of the test of the samples it carries.

When the test result of the sample indicates that the sample needs to be retested, the corresponding sample rack in the buffer 30 is moved out of the buffer 30 and into the feeding channel 10 — specifically, the transfer scheduling mechanism 50 moves and aligns with the buffer bit 31 where the sample rack is located, if the sample rack is located in the buffer 30 on the left side in the figure, the sample rack moves in the direction opposite to the first direction to enter the transfer scheduling mechanism 50, and if the sample rack is located in the buffer 30 on the right side in the figure, the sample rack moves in the first direction to enter the transfer scheduling mechanism 50; the transfer scheduling mechanism 50 moves to the second direction to align with the feeding channel 10 after receiving the sample rack, then the sample rack moves to the direction opposite to the first direction to enter the feeding channel 10 so that the sample to be retested passes through the sample sucking position, so that the sample to be retested is sucked by the analysis equipment, after all the samples to be retested on the sample rack are sucked, the sample rack moves to the transfer scheduling mechanism 50 from the feeding channel 10 along the first direction, the transfer scheduling mechanism 50 moves to the direction opposite to the second direction again to dispatch the sample rack back to the buffer area 30 again, of course, in some test modes, the sample only needs to be retested once, namely, after the sample is sucked for the first time, the result to be tested is in the buffer area, if the test result indicates that the retesting is needed, the sample is retested, and then the sample does not need to wait for the test result of the retesting again, but is dispatched directly, for example to the unloading zone, in which mode after all the samples to be retested on the sample rack have been taken up, the sample rack is again moved in the first direction from the feed channel 10 to the transfer dispatch mechanism 50, is further moved in the first direction from the transfer dispatch mechanism 50 to the unloading channel 60 and finally through the unloading channel 60 to the unloading zone 70 in the opposite direction to the second direction-during which process the sample rack may need to be moved a distance in the first direction along the unloading channel 60 and then moved in the opposite direction to the second direction to the unloading zone 70.

When the test results of all samples on a sample rack in the buffer area 30 indicate that the corresponding sample does not need to be retested, the corresponding sample rack in the buffer area 30 is moved out of the buffer area 30 and finally moved into the unloading area 70 — the transfer scheduling mechanism 50 moves and aligns with the buffer bit 31 where the sample rack is located, if the sample rack is located in the buffer area 30 on the left side in the figure, the sample rack moves in the direction opposite to the first direction to enter the transfer scheduling mechanism 50, and if the sample rack is located in the buffer area 30 on the right side in the figure, the sample rack moves in the first direction to enter the transfer scheduling mechanism 50; after the transfer mechanism 50 receives the sample rack, it moves in the second direction to align with the unloading channel 60, and the sample rack enters the unloading channel 60 from the transfer mechanism 50 in the first direction, and finally enters the unloading area 70 through the unloading channel 60 in the direction opposite to the second direction — during this process, the sample rack may need to move a distance along the unloading channel 60 in the first direction and then enter the unloading area 70 in the direction opposite to the second direction.

The scheduling and testing process of the sample rack carrying the emergency treatment sample is similar, and after the user puts the sample rack in the emergency treatment area 40, the sample rack moves from the emergency treatment area 40 to the first direction to enter the buffer area 30 communicated with the sample rack; of course, for embodiments in which the emergency area 40 is disposed in the buffer area 30, for example, if one of the buffer bits 31 in the buffer area 30 is set as the emergency bit 41, the sample rack carrying the emergency sample is already located in the buffer area 30. The sample rack is moved out of the buffer area 30 and into the feeding channel 10. specifically, the transfer scheduling mechanism 50 moves and aligns with the buffer location 31 where the sample rack is located, which is shown in the right buffer area 30 in the figure, so that the sample rack moves in the first direction to enter the transfer scheduling mechanism 50; the transfer scheduling mechanism 50 is adapted to the sample rack, and then moves in the second direction to align with the feeding channel 10, and then the sample rack moves in the opposite direction to the first direction to enter the feeding channel 10 so that each sample passes through the sample sucking position one by one, so that each sample of the sample rack is sucked by the analyzing equipment, after each sample on the sample rack is sucked, the sample rack enters the transfer scheduling mechanism 50 from the feeding channel 10 in the first direction, and the transfer scheduling mechanism 50 moves in the opposite direction to the second direction to reschedule the sample rack back to the buffer area 30, and the purpose of the sample rack entering the buffer area 30 at this time is to wait for the test result of the sample carried by the sample rack. When the sample rack carrying the emergency sample indicates that the sample needs to be retested according to the test result of the sample, the sample rack needs to go to the feeding channel 10 again to retest the corresponding sample, i.e. the specific scheduling process can participate in the above description, which is not repeated herein; similarly, when the test results of all samples on the sample rack carrying the emergency treatment samples indicate that the corresponding samples do not need to be retested, the sample rack is removed from the buffer area 30 and finally moved into the unloading area 70 — a specific scheduling process may participate in the above description, which is not described herein again.

In some embodiments of the present application, methods of autosampling control are also disclosed, which may be applied to the autosampling devices disclosed in any of the embodiments herein.

Referring to fig. 13, the method for controlling automatic sample injection in some embodiments includes the following steps:

step 100, i.e. the sample rack deposit step, controls the movement of the sample rack from the loading zone 20 to the feed channel 10 in the second direction.

Step 120, i.e. the sample rack feeding step, controls the sample rack to move along the feeding channel 10 in the first direction to the sample sucking position on the feeding channel 10 for sample sucking.

In step 140, i.e. the sample rack buffering step, the transfer scheduling mechanism 50 is controlled to move the sample rack that has been subjected to the sample suction and is moved out of the feeding channel 10 to the buffer 30 in the direction opposite to the second direction, and to drive the sample rack to move into the buffer 30 in the direction same as or opposite to the first direction to wait for the test result.

By way of example, and not limitation, in fig. 8, 11 or 12, after all the samples on the sample rack are taken, the sample rack continues to move in the first direction from the feeding path 10 to the transfer scheduling mechanism 50, and after the transfer scheduling mechanism receives the sample rack, the sample rack is moved in the direction opposite to the second direction and then stops aligned with an empty buffer bit 31 — if the empty buffer bit 31 is in the buffer area 30 on the left in the figure, the sample rack moves in the first direction to enter the buffer area 30 on the left, and if the empty buffer bit 31 is in the buffer area 30 on the right in the figure, the sample rack moves in the direction opposite to the first direction to enter the buffer area 30 on the right. The purpose of the sample rack entering the buffer 30 is to wait for the results of the test of the samples it carries.

And 150, namely a retest step, when the test result of the sample indicates that the sample needs to be retested, controlling the transfer scheduling mechanism to take out the sample rack corresponding to the retest instruction in the buffer area along the direction opposite to the first direction or the same direction, and then scheduling the sample rack to the feeding channel along the second direction so as to move into the sample sucking position along the feeding channel along the direction opposite to the first direction for sample sucking. It should be noted that the review instruction may be automatically generated when the sample analysis system, the analysis device, or the automatic sample introduction device determines that there is a sample to be reviewed, or may be issued by a user through a mouse or a keyboard, for example, after the user sees a test result on a display interface, the user manually designates the sample on a certain sample rack to be reviewed.

Taking fig. 8, fig. 11 or fig. 12 as an example, when the test result of the sample indicates that the sample needs to be retested, the corresponding sample rack in the buffer 30 is moved out of the buffer 30 and into the feeding channel 10 — specifically, the transfer scheduling mechanism 50 moves and aligns with the buffer bit 31 where the sample rack is located, if the sample rack is located in the buffer 30 on the left side in the figure, the sample rack moves in a direction opposite to the first direction to enter the transfer scheduling mechanism 50, and if the sample rack is located in the buffer 30 on the right side in the figure, the sample rack moves in the first direction to enter the transfer scheduling mechanism 50; the transfer scheduling mechanism 50 is moved in the second direction to align with the feeding channel 10 after receiving the sample rack, and then the sample rack is moved in the opposite direction to the first direction to enter the feeding channel 10 so that the sample to be retested passes through the sample sucking position, so that the sample to be retested is sucked by the analyzing apparatus. After all the samples to be retested on the sample rack are sucked, the sample rack enters the transfer scheduling mechanism 50 from the feeding channel 10 in the first direction, and the transfer scheduling mechanism 50 moves in the direction opposite to the second direction to reschedule the sample rack back to the buffer area 30, however, in some test modes, the samples only need to be retested once, that is, after the samples are sucked for the first time, the results to be tested are in the buffer area, if the test results indicate that the retesting is needed, the samples are retested, and then the samples do not need to wait for the test results of the retesting, but are directly scheduled to go away, for example, to the unloading area, in this mode, after all the samples to be retested on the sample rack are sucked, the sample rack enters the transfer scheduling mechanism 50 from the feeding channel 10 in the first direction, and then continues to enter the unloading channel 60 from the transfer scheduling mechanism 50 in the first direction, and finally into the unloading zone 70 through the unloading channel 60 in a direction opposite to the second direction-during which the sample rack may need to be moved a distance along the unloading channel 60 in the first direction and then into the unloading zone 70 in a direction opposite to the second direction.

In some cases, when a sample rack needs to enter the feed channel 10 from the buffer area 30 for retesting, there may be a sample rack on the feed channel 10 itself, and this complicated situation needs to be handled by some avoidance strategies.

In some embodiments, the review step 150 may include: when the test result of the sample indicates that the sample needs to be retested, the sample rack located in the sample suction position is controlled to move out along the feeding channel, which means that the sample rack exists on the feeding channel 10 at this time, and the sample on the sample rack is located in the sample suction position, so that the samples on the sample rack in the sampling process can be completely sucked, and then the transfer scheduling mechanism 50 is controlled to schedule the sample rack to the buffer area 30 to wait for the test result. And then the transfer scheduling mechanism 50 is controlled to take out the sample rack corresponding to the review instruction in the buffer area along the direction same as or opposite to the first direction, and then schedule the sample rack to the feeding channel along the direction opposite to the second direction, so as to move to the sample sucking position along the feeding channel in the direction opposite to the first direction for sample sucking.

In some embodiments, the review step 150 may include: when the test result of the sample indicates that the sample needs to be retested, the sample rack located in the sample sucking position is controlled to move out along the feeding channel in the direction opposite to the first direction, which means that the sample rack exists on the feeding channel 10 at the moment, and the sample on the sample rack is located at the sample sucking position, so that the sample rack can be moved in the direction opposite to the first direction to make the sample sucking position; and then controlling the transfer scheduling mechanism 50 to take out the sample rack corresponding to the review instruction in the buffer area along the direction same as or opposite to the first direction, and then scheduling the sample rack to the feeding channel along the direction opposite to the second direction so as to move to the sample sucking position along the feeding channel along the direction opposite to the first direction for sample sucking.

It can be seen that the avoidance strategy is implemented by controlling the movement of the specimen holder on the feed channel for avoidance. Thus, in some embodiments, the review step 150 may include: and when the sample rack in the feeding channel is judged to exist, controlling the sample rack on the feeding channel to move so as to avoid.

In particular embodiments, processing may be from the perspective of whether one or more sample racks are currently on the feed path 10. In some embodiments, the controlling the movement of the specimen rack on the feed channel to avoid includes: when it is determined that only one sample rack exists on the feeding channel 10, the sample rack is controlled to move on the feeding channel for avoiding, for example, the sample rack is controlled to move to the sample sucking position so that each sample on the sample rack is sucked completely, and then the sample rack is controlled to move on the feeding channel for avoiding — for example, the transfer scheduling mechanism 50 is controlled to schedule the sample rack with the sucked sample to the buffer area 30 to wait for a test result, or the sample rack is controlled to move in a direction opposite to the first direction so as to leave the sample sucking position. In some embodiments, the controlling the movement of the specimen rack on the feed channel to avoid includes: when a plurality of sample racks are judged to exist on the feeding channel 10, the sample rack closest to the sample sucking position is controlled to move to the sample sucking position so that each sample on the sample rack is completely sucked, and then the sample rack with the sample sucking completed is controlled to move out of the feeding channel, for example, the transfer scheduling mechanism 50 is controlled to schedule the sample rack with the sample sucking completed to the buffer area 30 to wait for a test result, and other sample racks on the feeding channel are controlled to move on the feeding channel for avoiding, for example, the other sample racks are controlled to move on the feeding channel 10 in a direction opposite to the first direction so as to leave the sample sucking position, and even the sample rack can be controlled to re-enter the loading area 20.

In particular embodiments, this can also be dealt with from the point of view of whether the feed channel 10 is fully loaded or not. In some embodiments, the controlling the movement of the specimen rack on the feed channel to avoid includes: when the feed channel 10 is judged to be not fully loaded, the sample racks are controlled to move on the feed channel 10 for avoiding, for example, the sample racks are controlled to move on the feed channel 10 in a direction opposite to the first direction to make the sample sucking position, and even the sample racks can be controlled to re-enter the loading area 20. In some embodiments, the controlling the movement of the specimen rack on the feed channel to avoid includes: when the feeding channel is judged to be full, the sample rack closest to the sample sucking position is controlled to move to the sample sucking position so that each sample on the sample rack is completely sucked, and then the sample rack with the sample sucking completed is controlled to move out of the feeding channel, for example, the transfer scheduling mechanism 50 is controlled to schedule the sample rack with the sample sucking completed to the buffer area 30 to wait for a test result, and other sample racks on the feeding channel are controlled to move on the feeding channel for avoiding, for example, the other sample racks are controlled to move on the feeding channel 10 in a direction opposite to the first direction so as to make the sample sucking position, and even the sample rack can be controlled to re-enter the loading area 20.

Through the avoidance strategies and the specific methods, samples needing to be rechecked can be preferentially processed as much as possible, so that the time for obtaining the result of the final sample meets the requirements of departments.

Referring to fig. 14, the method for controlling automatic sample injection in some embodiments includes the following steps:

In step 140, i.e. the sample rack buffering step, the transfer scheduling mechanism 50 is controlled to move the sample rack that has been subjected to the sample suction and is moved out of the feeding path 10 to the buffer 30 in the direction opposite to the second direction, and to drive the sample rack to move into the buffer 30 in the direction same as or opposite to the first direction.

Step 160, i.e. the emergency treatment step, in response to the emergency treatment instruction input by the user, controls the transfer scheduling mechanism to move the sample rack from the buffer area 30 out of the buffer area 30 in the same direction or in the opposite direction to the first direction and to the feeding channel 10 in the second direction, so that the sample rack is moved to the sample sucking position along the feeding channel 10 in the opposite direction to the first direction.

In some examples, the emergency area 40 is an area in communication with the buffer area 30, and the emergency step 160 further includes: in response to the emergency instruction input by the user, the sample rack located in the emergency area 40 is controlled to move from the emergency area 40 to the communicated buffer area 30 in the same or opposite direction as the first direction. Specifically, step 160 includes a first emergency step of controlling the sample rack located in the emergency area 40 to move from the emergency area 40 to the buffer area 30 in communication in the same or opposite direction as the first direction in response to the emergency instruction input by the user; controlling the sample rack to move out of the buffer area 30 from the buffer area 30 in the same direction or the opposite direction to the first direction; controlling the sample rack moved out of the buffer area 30 to move along a second direction; the sample rack is controlled to move into the feeding channel 10 and move along the feeding channel 10 to the sample sucking position in the direction opposite to the first direction.

In some examples, the buffer area 30 has the emergency treatment area 40 disposed therein, or the buffer bits 31 are set as the emergency treatment bits 41, then the emergency treatment step 160 directly controls the sample rack in the emergency treatment bits 41 in the buffer area 30 to move out of the buffer area 30 from the buffer area 30 in the same or opposite direction as the first direction and move to the feeding channel 10 in the second direction in response to the emergency treatment instruction input by the user. Specifically, step 160 includes a second emergency step of controlling the sample rack on the emergency position 41 in the buffer area 40 to move out of the buffer area 30 in the same direction or the opposite direction to the first direction in response to the emergency instruction input by the user; controlling the sample rack moved out of the buffer area 30 to move along a second direction; the sample holder is controlled to move into the feed channel 10 and along the feed channel to the pipetting station in a direction opposite to the first direction.

In some cases, when a sample rack carrying an emergency sample needs to enter the feed channel 10 from the buffer area 30 for testing, there is a possibility that the sample rack itself exists on the feed channel 10, and at this time, a avoidance strategy needs to be adopted to deal with the complicated situation.

In some embodiments, the emergency step 160 further comprises: when the sample rack is judged to exist in the feeding channel 10, the sample rack on the feeding channel is controlled to move to avoid.

Through the avoidance strategies and the specific method, the samples needing emergency treatment can be preferentially processed as far as possible, and the requirement of the sample result time needed by the emergency treatment samples is met.

After all samples on the sample rack carrying the emergency treatment are sucked, controlling the sample rack which is sucked at the sample sucking position to move out of the feeding channel 10 in the first direction; the transfer scheduling mechanism 50 is controlled to move the sample rack moved out of the feeding path 10 in the direction opposite to the second direction and move it into the buffer area 30 in the same direction as or opposite to the first direction to wait for the test result. When the test result of the emergency sample indicates that the emergency sample needs to be retested, performing a retest step, and scheduling the corresponding sample rack for retest, wherein the specific process has been described above, and is not described herein again.

Referring to fig. 15 and 16, the method for controlling automatic sample injection in some embodiments may further include a step 170 of unloading, when the test result of each sample on a sample rack in the buffer area 30 indicates that the corresponding sample does not need to be retested, controlling the sample rack to move out of the buffer area 30 from the buffer area 30 in a direction same as or opposite to the first direction, controlling the sample rack moving out of the buffer area 30 to move in a direction same as the second direction, controlling the sample rack to move into the unloading channel 60, and moving the sample rack to move into the unloading area 70 from the unloading channel 60 in a direction opposite to the second direction, during which the sample rack may need to move a distance along the unloading channel 60 in the first direction and then move into the unloading area 70 in the direction opposite to the second direction.

The sample analysis system, the analysis equipment, the automatic sample introduction device and the dynamic sample introduction control method are disclosed in the application. The sample analysis system, the analysis equipment and the automatic sampling device are compact in structure, and can realize conventional sampling, quick emergency sampling and quick rechecking. The automatic sampling device can be independent of the analysis equipment, and when the analysis equipment needs to be connected into the assembly line system, the automatic sampling device can be detached. In addition, when the analysis device needs to perform a large batch of sample tests compared with the designed capacity, a capacity expansion module may be added outside, the capacity expansion module transports the sample rack carrying the sample to be tested to the loading area 20 through the rail, and after the test is completed, the sample rack in the unloading area 70 may be transferred out through the rail. In addition, the automatic sample feeding device may also provide a plurality of feeding channels 10, and a buffer area 30 and a transit scheduling mechanism 50 matched with each feeding channel 10 in the first direction to supply samples to a plurality of analysis devices (each feeding channel 10 supplies samples to one analysis device), thereby realizing the cascade connection of the plurality of analysis devices.
