Description

Sample introduction system and sample recovery method

Technical Field

The invention relates to a sample introduction system and a sample recovery method.

Background

An in vitro diagnostic device is a device that detects a human body sample (blood, body fluid, tissue, etc.) to obtain clinical diagnostic information and then determines a disease or a body function, outside the human body.

In the in vitro diagnostic apparatus, a sample introduction System (SDM) is mainly used to carry a sample rack placed by a user, identify barcode information of the sample rack and a sample tube on the sample rack, schedule and transmit the sample rack to a predetermined position, for example, schedule and transmit the sample rack to a sample suction position, schedule and transmit the sample rack which finishes the sample suction to a recovery area, and the like.

The existing sample introduction system has the advantages that samples are carried in a basket carrying mode, the baskets can be placed in the placing area and the recovery area, the baskets in the placing area bear the samples to be introduced, and the baskets in the recovery area bear the recovered samples. From the perspective of the user, on the one hand, the user places the samples to be injected into the baskets in batches, then places the baskets into the placing area, and on the other hand, the user places the non-full baskets into the recovery area to recover the samples, and then takes out the baskets from the recovery area when needed.

Existing sample introduction systems often have a situation that a basket is taken away by a user when a sample to be recovered is being dispatched to a path of a recovery area basket, which may cause many adverse effects, for example, the sample being recovered may not be correctly dispatched to the recovery area basket, for example, the sample may not be dispatched to the recovery area basket and may stop at a certain position, thereby preventing a path of system sample introduction, and the system sample introduction may stop, for example, if the recovered sample is being pushed into the basket, the basket is taken away at this time, which may cause the sample to be dumped into equipment, and the like.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.

Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. 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).

The sample introduction system is a system for dispatching samples and completing sample introduction and recovery. The scheduling unit of the sample injection system may be a sample rack, and it should be noted that the sample rack may be a sample rack having a plurality of sample positions, that is, the sample rack may carry a plurality of samples, or the sample rack may be a sample rack having only one sample position, that is, the sample rack may only carry one sample, which is described in detail below.

The sample rack is loaded with one or more sample tubes, each sample tube is filled with a sample, the sample injection system is dispatched by taking the sample rack as a unit, the sample racks are dispatched to the sample sucking position from the lifting basket of the putting-in area so as to suck the samples on the sample racks, then the samples are supplied to a mechanism for analyzing and measuring the samples, and finally the sample racks are dispatched to the lifting basket of the recovery area to wait for the user to take away the samples together with the lifting basket.

Referring to FIG. 1, an embodiment of a sample injection system may comprise one or more input regions and one or more recovery regions, and is schematically illustrated with two input regions arranged side by side and two recovery regions arranged side by side. Of course, in some embodiments, the sample injection system may include only the recovery zone, and not the input zone. FIG. 1(a) is a schematic diagram of a position schedule in which a sample rack is scheduled from a loading area to a pipetting position: the placing area is used for placing a lifting basket, a sample to be sampled is carried in the lifting basket, and the sample frame of the placing area is dispatched to a sample sucking position by the sample feeding system so as to suck the sample. FIG. 1(b) is a schematic diagram of a position schedule where samples that have completed the draw are scheduled to the recovery area: and dispatching the sample rack subjected to sample suction from the suction position to a basket in the recovery area, and recovering the sample rack from the basket in the recovery area by a user. Of course, some failed sample racks and samples are also dispatched to the baskets in the recovery area.

The placing area and the recovery area can be collectively called as placing areas, the above examples are examples in which the placing area is used for placing samples to be injected, and the recovery area has a recovery function. When a sample or a sample rack needs to be dispatched to a basket in the placement area for recycling, we can also refer to the placement area as a recycling area directly, since the placement area at least has the function of a recycling area.

Fig. 2 is a schematic diagram of a practical mechanical structure of a basket, wherein the placing area carries the basket, and the basket carries a sample rack or a sample (the basket directly carrying the sample rack is shown). After a user loads the sample rack on the lifting basket, the lifting basket is placed in the placing area, and therefore the sample injection system can finally dispatch the sample rack to a sample sucking position from the lifting basket; the user places the basket that is not full in the recovery area, and sample introduction system just can push the sample frame that inhale the appearance and accomplish again finally to the basket that is located in the recovery area like this, and after the basket carried the sample frame fully, the user can take out this basket from the recovery area. In order to prevent the sample rack from toppling in the basket, the basket of one embodiment is provided with an anti-falling structure near one end of the basket for pushing in and pushing out the sample rack, so as to prevent the sample rack from falling off the basket, and when the basket is placed in the placing area, the anti-falling structure is triggered to be in an unlocking state, as shown in fig. 3 (a); when the basket is taken out from the placing area, the anti-dropping structure is gradually reduced from the unlocking state to the locking state, as shown in fig. 3 (b).

It should be noted that, in the present invention, the placing area carries or places the sample, including directly carrying the sample and indirectly carrying the sample, for example, the placing area may carry a plurality of sample racks, each sample rack carries a plurality of samples, and for example, the placing area may carry a basket that can be put in and taken out, and the basket is used for carrying a plurality of samples. Similarly, a sample rack carrying a plurality of samples may refer to a sample rack carrying a plurality of sample tubes, each sample container holding a sample. Similarly, the carrier is used to carry a plurality of samples, and may also be referred to as a carrier that carries a plurality of samples by carrying a plurality of sample racks.

The sampling system of an embodiment has introduced basket locking device and has locked the basket of recovery area, if there is the sample frame to need to retrieve at present, with the basket locking of recovery area, prevent when having the sample frame to need to retrieve, the condition that the basket of recovery area was but was taken away by the user, if there is not the sample frame to need to retrieve at present, then with the basket unblock of recovery area to make things convenient for the user to take away. Thus, the present application may lock the basket when it is not desired to have the user remove the basket (typically as is the case when there is a sample/rack that needs to be retrieved at the present time) so that the basket is not removed; and the basket can be unlocked in time under other conditions (such as the conditions that no sample/sample rack needs to be recycled at present) that can allow the user to remove the basket, so that the user can conveniently take the basket.

This will be explained in detail below.

Referring to fig. 4, the sample injection system of an embodiment includes a recovery area 10, a dispatching unit 20, a basket locking device 30, and a controller 40. The recovery zone 10 is for carrying a basket to receive a sample to be recovered. The scheduling component 20 is used for scheduling samples, for example by scheduling sample racks to achieve scheduling of samples carried on the sample racks. The basket locking means 30 is used to lock the baskets placed on the recycling area 10 in the recycling area so that they cannot be taken away by the user. It will be appreciated by those skilled in the art that if the sample injection system includes multiple recovery sections 10, then each recovery section may be configured with a basket locking device 30. It should be noted that fig. 4 shows a case with two recovery areas 10, and it is understood by those skilled in the art that this is not used to limit the sample injection system to only include two recovery areas 10, for example, the sample injection system may include one recovery area 10, or may include a plurality of recovery areas 10.

Referring to fig. 5, the sample injection system of an embodiment may further include a buffer 11, for example, the buffer 11 is disposed in the sample injection system to assist the scheduling of the sample and provide a transit and buffer position for the sample. In one embodiment, the sample injection system may comprise multiple layers, one layer is used for setting the loading area and the recovery area, etc., and another layer, such as the lower layer, is used for setting the buffer area 11, which can save space and make the sample injection system compact. The buffer zone 11 herein is capable of storing one or more sample racks. The buffer 11 herein may be sized and dimensioned according to the daily throughput or throughput of the sample injection system. The buffer 11 may be designed for a number of functions, several of which are tried out below.

A particular function of the buffer area 11 may be as a transfer station for the sample rack to be buffered while it is being dispatched from the loading area to the aspirating position. Due to the existence of the buffer area 11, a plurality of sample racks are dispatched to the buffer area 11 in batches, and then the dispatching component 20 dispatches the sample racks to the sample sucking positions in sequence from high to low according to the sample sucking priority of the sample racks. For example, a sample rack requiring an emergency treatment has a higher priority than a normal sample rack, and a sample rack which is applied for a test first in the normal sample rack has a higher priority than a sample rack which is applied for a test later. One structure of the buffer area 11 is shown in fig. 6, where the buffer area 11 includes a plurality of lanes, each lane may be used to place a sample rack, and the scheduling component 20 may schedule the sample rack buffered by the lane from any lane, for example, to a sample sucking position or a recovery area.

A specific function of the buffer 11 may also be to buffer a sample rack that has been subjected to sample suction, so that a sample on the sample rack may wait for a test result of a project at the buffer 11, if the test result of the project is normal, the sample rack may be dispatched from the buffer 11 to the recovery 10 for recovery, if the test result of the project is abnormal, it indicates that a corresponding sample on the sample rack needs to retest the project, the sample rack may be dispatched from the buffer 11 to a sample suction position, the corresponding sample may be sampled to retest the project with an abnormal test result, and then the sample rack may continue to return to the buffer 11 to wait for whether the test result of the retest project is normal, or may be directly dispatched to the recovery, i.e., no longer wait for the test result of the retest project. It should be noted that, the abnormal test result of a certain item of the sample generally means that at least one test parameter result of the item is not within a preset range, and if the test parameter results of the item of the sample are all within the corresponding preset ranges, the test result of the item is normal.

The following is a description of the flow of sample recycling control of the sample injection system.

The controller 40 of an embodiment is configured to control the sample recovery when it is determined that a sample needs to be dispatched to the recovery area, and the controller 40 controls the sample recovery. The whole process of the controller 40 controlling the sample recovery will be described below.

For samples that need to be dispatched to the recovery zone 10, the controller 40 in one embodiment controls sample recovery including: the controller 40 controls the basket locking device 30 to lock the basket of the recovery area 10 and controls the dispatching part 20 to dispatch the sample into the basket.

To ensure that the recovery area 10 has a basket available, the controller 40 in one embodiment further introduces a determination process, and specifically, the controller 40 controls the sample recovery including:

it is determined whether there are any baskets available in the recovery zone 10.

When it is determined that there is a basket available in the recycling area 10, the controller 40 controls the basket locking device 30 to lock the basket in the recycling area 10, and controls the dispatching part 20 to dispatch the sample into the basket. In an embodiment, for the case that the sample injection system has a plurality of recovery areas 10, when the controller 40 determines that there are available baskets in the plurality of recovery areas 10, the recovery area 10 closest to the outside of the sample injection system in the recovery areas 10, for example, the recovery area on the right side in fig. 1 is closer to the outside of the sample injection system than the recovery area on the left side, is selected as the recovery area for receiving the sample to be currently recovered, so that the recovery area 10 outside the sample injection system can be preferentially filled with the sample, which is convenient for the user to take.

When determining that the recovery section 10 has no basket available-it is understood that for a sample injection system having multiple recovery sections 10, determining that the recovery section 10 has no basket available means that there is no basket available on all recovery sections 10 in the sample injection system-the controller 40 may employ at least one of the following:

in a first mode, the controller 40 generates a prompt to the user that no baskets are available in the recovery area. For example, the sample introduction system may be provided with a speaker or a display screen, etc., and an audio file is played through the speaker or displayed through the display screen to prompt the user that the recycling area 10 has no basket available; as another example, the sample injection system may include an indicator light for each recovery area 10, and the user may be informed of the status of the indicator light, such as color, bright, dim, flashing, etc., that no basket is available in the recovery area.

In a second mode, the controller 40 controls the dispatching component 20 to dispatch the samples to be dispatched to the recovery area 10 to the buffer area 11 to wait for an available basket to be placed in the recovery area 10.

In one embodiment, the controller 40 determines whether any baskets are available in the recovery area 10, which may be determined at one or more times. Firstly, a specific path structure of a sample dispatching system to a recovery area is explained. Referring to fig. 7, the sample injection system includes a recycling channel 12, the recycling channel 12 has a through port 12a connected to the recycling area 10, it can be understood that, if the sample injection system has a plurality of recycling areas 10, the recycling channel 12 has a through port 12a connected to the recycling area 10 for each recycling area 10; the recovery channel 12 also has an inlet 12b for the sample to enter the recovery channel 12. Therefore, for the sample to be dispatched to the recovery area 10, the dispatching component 20 dispatches the sample to the entrance 12b of the recovery passage 12, dispatches the sample into the recovery passage 12 through the entrance 12b, and dispatches the sample to the basket of the recovery area 10 corresponding to the through-hole 12a of the recovery passage 12. The controller 40 determines whether there is a basket available in the recycling area 10, and the determination may be at least one of the following:

the first time is when the controller 40 judges that a sample needs to be scheduled to the recovery area 10; that is, when the controller 40 determines that there is a sample to be dispatched to the recovery area 10, the controller 40 determines whether there is a basket available in the recovery area 10. For example, when the sample is completely sucked at the sample sucking position, the controller 40 determines that the sample needs to be dispatched to the recovery area 10, and for example, when the sample waits for the item test result in the buffer area 11, and when the item test result is determined to be normal, the controller determines that the sample needs to be dispatched to the recovery area 10.

Opportunity two is when the sample is scheduled to the inlet 12b of the recovery channel 12; i.e., immediately before the sample is dispatched to the inlet 12b of the recovery channel 12 into the recovery channel 12, the controller 40 now determines whether a basket is available in the recovery section 10.

It should be noted that, the controller 40 controls the flow of sample recovery, and may be configured to control the basket locking device 30 to lock the basket in the recovery area 10 and control the dispatching component 20 to dispatch the sample to the basket when it is determined that there is a sample to be dispatched to the recovery area; or when it is determined that there is a sample to be dispatched to the recovery area, the above-mentioned step of determining whether there is an available basket in the recovery area 10 is performed first, and then the subsequent process is performed according to the determination result.

The process of the controller 40 controlling the basket locking device 30 to lock the basket of the recovery zone 10 will be described below.

The basket locking device 30 locks the basket of the recycling region 10 by performing a locking action, and the controller 40 controls the basket locking device 30 to lock the basket of the recycling region 10 includes:

the controller 40 determines whether the basket locking means 30 performs the locking action properly.

When the controller 40 determines that the basket locking means 30 does not perform the locking action properly, it may take at least one of the following manners:

in a first mode, the controller 40 generates a prompt for the user that the basket in the recovery area is not properly locked. For example, the sample introduction system may be provided with a speaker or a display screen, etc., and an audio file is played through the speaker or displayed through the display screen to prompt a user that a basket in the recovery area is not correctly locked; for another example, the sample injection system may set an indicator light in each recovery area 10, and prompt the user that the basket in the recovery area is not locked correctly through the status of the indicator light, such as color, long bright, no bright, flashing, etc.

In the second mode, in the case that the sample injection system has one or more recovery areas 10, when the controller 40 determines that the basket locking device 30 does not perform the locking operation correctly, it can directly control the scheduling unit 20 to schedule the samples to be scheduled to the recovery areas to the buffer area 11.

In a third mode, for a case where the sample injection system has a plurality of recovery areas 10, when the controller 40 determines that the basket locking device 30 does not correctly perform the locking action, in addition to the measure of directly controlling the scheduling unit 20 to schedule the sample to be scheduled to the recovery area to the buffer area 11 in the second mode, a mode of switching to another recovery area 10 may also be adopted, specifically: when the controller 40 judges that the basket locking device 30 does not correctly perform the locking action, it judges whether other recovery areas 10 have available baskets, and if it judges that other recovery areas 10 have available baskets, the controller 40 controls the recovery of the sample for the recovery areas 10 having available baskets, and understandably, if it judges that a plurality of recovery areas 10 have available baskets, the controller 40 may select one of the recovery areas 10 as the recovery area 10 for receiving the sample to be currently recovered, for example, select the recovery area 10 closest to the outside of the sample introduction system among the recovery areas 10; if it is determined that no basket is available for the other recycling region 10, the controller 40 controls the scheduling unit 20 to schedule the samples that need to be scheduled to the recycling region to the buffer region 11. It should be noted that the relationship between the second and third modes is "or", that is, the controller 40 can only select one of them.

The controller 40 continues to determine whether the basket is in place when it is determined that the basket locking device 30 correctly performs the locking operation.

When the controller 40 determines that the basket is in place, it controls the scheduling unit 20 to schedule the sample in the basket.

When the controller 40 determines that the basket is not in place, it may adopt at least one of the following modes:

in a first mode, the controller 40 generates a prompt to prompt the user that the basket in the recovery area is not in place. For example, the sample introduction system may be provided with a speaker or a display screen, etc., and an audio file is played through the speaker or displayed through the display screen to prompt a user that the basket of the recovery area 10 is not in place; for another example, the sample injection system may set an indicator light in each recovery area 10, and prompt the user that the basket of the recovery area 10 is not in place by the status of the indicator light, such as color, long bright, no bright, flashing, etc.

In a second way, for the case that the sample injection system has one or more recovery areas 10, when the controller 40 determines that the basket is not in place, it may directly control the scheduling unit 20 to schedule the samples that need to be scheduled to the recovery areas to the buffer area 11.

In a third mode, for a case that the sample injection system has a plurality of recovery areas 10, when the controller determines that the basket is not in place, in addition to a measure of directly controlling the scheduling component 20 to schedule the sample to be scheduled to the recovery area to the buffer area 11 in the second mode, a mode of switching to another recovery area 10 may also be adopted, specifically: when the controller 40 judges that the baskets are not in place, the controller 40 judges whether other recovery regions 10 have available baskets, and if the other recovery regions 10 have available baskets, the controller 40 controls the recovery of the sample for the recovery regions 10 having available baskets, and understandably, if a plurality of recovery regions 10 have available baskets, the controller 40 may select one of the recovery regions 10 as the recovery region 10 for receiving the sample to be currently recovered, for example, the recovery region 10 closest to the outside of the sample injection system among the recovery regions 10; if it is determined that no basket is available for the other recycling region 10, the controller 40 controls the scheduling unit 20 to schedule the samples that need to be scheduled to the recycling region to the buffer region 11. It should be noted that the relationship between the second and third modes is "or", that is, the controller 40 can only select one of them.

All the above mentioned cases that the controller 40 dispatches the samples to be dispatched to the recovery area 10 to the buffer area 11, for example, when the controller 40 determines that the recovery area 10 has no available basket, when it determines that the basket locking device 30 has not correctly performed the locking action, and when it determines that the basket is not in place, measures to dispatch the samples to be dispatched to the recovery area 10 to the buffer area 11 can be taken. After the controller 40 of an embodiment controls the dispatching component 20 to dispatch the sample to be dispatched to the recovery area to the buffer area 11, the controller 40 monitors whether the recovery area 10 has an available basket — understandably, in case of a sample injection system having a plurality of recovery areas 10, the controller 40 monitors whether the recovery area 10 has an available basket, the monitored objects are all the recovery areas 10 in the sample injection system — once the recovery area 10 has an available basket, the controller 40 controls the sample to be dispatched for the recovery area having the available basket.

The process of controlling the sample recovery by the controller 40 of an embodiment may further include: the controller 40 unlocks the basket of the recovery zone after controlling the dispatch section 20 to dispatch the sample to the basket.

It should be noted that, for the case that the sample collection system has multiple collection areas 10, the collection area currently used for collecting the sample is switched from one collection area to another collection area, and for the case that the sample is scheduled to the buffer area and temporarily stored and waits for the collection area with an available basket, for the new collection area used as the collected sample, the controller 40 still performs a complete sample collection process again when controlling the sample collection, such as determining whether the current collection area has an available basket, locking the basket of the collection area, determining whether the basket locking device of the collection area correctly performs a locking action, determining whether the basket is in place after determining that the basket locking device of the collection area correctly performs the locking action, unlocking the basket after the sample is scheduled to the basket of the collection area, and so on; of course, it will be understood by those skilled in the art that such a complete sample recovery procedure, as in some of the embodiments described herein, may be omitted.

Reference herein to a recovery zone having a basket available means that such a basket is placed in the recovery zone: the basket is not filled with the sample and is correctly placed in the recovery zone. The basket is not full of samples, which indicates that the basket can be further loaded and recycled; the sample may be properly dispatched to the basket of the retrieval area if the basket is properly positioned in the retrieval area, e.g., the basket is tilted at a corner when positioned in the retrieval area, such that the sample may topple over when dispatched to the basket of the retrieval area. In one embodiment of the invention, a basket in-place sensor is introduced to detect whether a basket in the recovery area is correctly placed or not, and a basket full-load sensor is introduced to detect whether the basket in the recovery area is full or not. Specifically, the basket in-place sensor is arranged in the recovery area and used for being triggered to generate an in-place signal when the basket is correctly placed in the recovery area; a basket full load sensor is disposed in the recovery zone for generating a full load signal when a basket of the recovery zone is full of a sample. Therefore, when the controller 40 detects an in-position signal and does not detect a full-load signal, the controller judges that the recovery area has an available basket; when the controller 40 detects the in-place signal, it determines that the basket in the recycling area is correctly placed in the recycling area, i.e. it determines that the basket is in place.

Referring to fig. 8, a partial structure of the recycling area 10 with a basket locking device 30 is shown, and specifically, two recycling areas 10 are shown, one of which is provided with a basket and the other is not provided with a basket. It can be seen from the recovery zone 10 where no baskets are located that a basket in-place sensor is provided which is triggered to generate an in-place signal only when a basket is correctly located in the recovery zone 10. If there is a gap between the basket and the recovery area or there is a foreign object, the basket may not trigger the basket-in-place sensor at this time, and the controller 40 determines that the basket is not in place currently.

The above is some description of sample collection control of the sample introduction system, and a description of the basket locking device 30 of the sample introduction system is provided below.

Referring to fig. 9, the basket locking device 30 of an embodiment includes a limiting member 110 and a driving member 130, which will be described in detail below.

The limiting part 110 can reciprocate between a first position and a second position, when the limiting part 110 is in the first position, the basket can be locked, that is, the user can not take out the basket from the recovery area 10 at the moment, when the limiting part 110 is in the second position, the basket is not locked, that is, the basket is in an unlocked state in the recovery area 10, and the user can take out the basket from the recovery area 10 at the moment.

There are various implementations of the limiting member 110, which are exemplified below.

Referring to fig. 10, the limiting component 110 of an embodiment may include a hook 111 and a fixing component 112 disposed on the sample injection system, for example, the fixing component 112 may be disposed below the recycling channel 12 connected to the recycling region 10. The hook claw 111 is provided in the fixed member 112 so as to be movable between a first position and a second position. The basket has the limit structure that the claw 111 was colluded in the cooperation, can cooperate with the limit structure of basket when colluding the claw 111 and being in the first position like this and lock the basket in recovery area 10, and the user can not take out the basket from recovery area 10, can not act on the limit structure of basket when colluding the claw 111 and being in the second position to make the basket be in the unblock state, the user can follow recovery area 10 and take out the basket. It should be noted that the hook 111 in fig. 10 can rotate around the fixing part 112 as an axis in the direction shown by the arrow in the figure, and lock the basket when moving to the first position by rotation, and unlock the basket when moving to the second position by rotation, and in fig. 10, the edge of the basket itself is used as the limiting structure of the basket to cooperate with the hook 111; FIG. 10 shows the catch 111 moved to a first position to lock the carrier; in addition, fig. 10 shows a partial structure of the sample injection system, which includes two recovery areas arranged side by side, wherein a basket is placed in one of the recovery areas 10.

Referring to fig. 11, the position limiting component 110 of an embodiment may include a pressing block 113 and a fixing component (not shown) disposed on the sample injection system, for example, the fixing component may be disposed below the recycling channel 12 connected to the recycling region 10. The pressing block 113 is disposed on the fixing member in a manner of being movable between a first position and a second position, and can press the basket in the recycling area 10 when the pressing block 113 is in the first position, so that the basket cannot be taken away by a user, and does not press the basket in the recycling area 10 when the pressing block 113 is in the second position, so that the basket can be taken away by the user. It should be noted that the pressing block 113 in fig. 11 can move up and down according to the direction shown by the arrow in the figure, and lock the basket when moving down to the first position, and unlock the basket when moving up to the second position; FIG. 11 shows the press block 113 moved to a first position to lock the basket; in addition, fig. 11 shows a partial structure of the sample injection system, which includes two recovery areas 10 arranged side by side, wherein a basket is placed in one of the recovery areas 10.

Referring to fig. 12, the position limiting component 110 of an embodiment may include a plug 115 and a fixing component 116 disposed on the sample injection system, for example, the fixing component 116 may be disposed below the recycling channel 12 connected to the recycling region 10. The latch 115 is provided to the fixing member 116 in such a manner as to be movable between a first position and a second position. The carrier has locating holes that mate with the latches 116. When the latch 115 is in the first position, the latch 115 can extend into the locating hole of the basket to lock the basket in the recycling area 10, so that the basket cannot be taken away by a user, and when the latch 116 is in the second position, the latch does not extend into the locating hole of the basket to lock the basket or unlock the basket, so that the user can take out the basket from the recycling area 10.

The driving member 130 is used to drive the limiting member 110 from any one of the first position and the second position to the other position. For example, the driving member 130 drives the limiting member 110 from the first position to the second position, so as to unlock the basket of the recovery area 10; the driving part 130 drives the restricting part 110 from the second position to the first position, thus completing the locking of the basket of the recovering zone 10. Thus, the driving of the stopper part 110 from the second position to the first position by the driving part 130 is defined as a locking action of the basket locking means.

In one embodiment, a basket locking device 30 may be disposed at each recovery area 10 of the sampling system, such that when the sampling system currently has a sample to be dispatched to the basket of the recovery area, the driving unit 130 drives the limiting unit 110 to the first position, thereby locking the basket of the recovery area, so that the sample can be dispatched to the basket of the recovery area 10 smoothly. When the sample is smoothly dispatched to the basket of the recovery area 10, or when no sample needs to be dispatched to the basket of the recovery area 10 currently in the sample injection system, the driving part 130 may drive the limiting part 110 to the second position, unlock the basket of the recovery area 10, and thus the user may take out the basket. In order to facilitate the sample injection system to determine whether the sample rack to be recovered can be dispatched to the basket in the recovery area, the basket locking device of an embodiment sends out a basket locking signal when the driving part 130 drives the limiting part 110 to the first position, and determines that the basket locking device 30 correctly performs the locking action when the controller 40 receives the basket locking signal.

There are various implementations of the driving part 130, which are exemplified below.

Referring to fig. 13, the driving member 130 of an embodiment may include a motor 131, a cam 132, and a reset member (not shown). It should be noted that for the embodiment of the driving member 130 implemented as a cam herein, the cam is said to be in the proximal position when the end of the cam near the cam rotation shaft moves to be close to the limiting member 110, and the cam is said to be in the distal position when the end of the cam far from the cam rotation shaft moves to be close to the limiting member 110. The motor 131 can drive the cam 132 to rotate along with the shaft to be in the remote position or the near position, and when the cam 132 rotates from the near position to the remote position, the limiting part 110 can be driven to the first position from the second position; when the cam 132 is rotated from the distal position to the proximal position, the reset member is activated to reset the spacing member 110 from the first position to the second position. In one embodiment, the return member may be implemented by a return spring. Referring to fig. 14, for example, the position limiting member 110 is implemented by the latch solution shown in fig. 12, when the end of the cam 132 abutting against the latch 115 is in the proximal position of the cam 132 (i.e. the end close to the rotational axis of the cam), the latch 115 is in the second position, the latch 115 does not extend into the positioning hole of the basket, and when the end of the cam 132 abutting against the latch 115 is in the distal position of the cam 132 (i.e. the end away from the rotational axis of the cam), the latch 115 is in the first position, and the latch 115 extends into the positioning hole of the basket to lock the basket in the recycling area 10. Fig. 14 shows the cam 132 in a remote position with the end of the cam 132 against the bolt 115, i.e., the cam 132 in a remote position. The motor 131 drives the cam 132 to rotate, when one end of the cam 132 against the bolt 115 is changed from the short-range position of the cam 132 to the long-range position of the cam 132, the bolt 115 is moved from the right to the left as indicated in the figure, that is, the bolt 115 moves from the second position to the first position, so that the bolt 115 extends into the positioning hole of the basket to lock the basket in the recycling area 10; when the end of the cam 132 that abuts against the latch 115 is changed from the remote position of the cam 132 to the near position of the cam 132, the latch 115 moves from the left to the right as indicated in the drawing under the action of the reset member, that is, the latch 115 moves from the first position to the second position, so that the latch 115 gradually retreats from the position that extends into the positioning hole of the basket, and the basket in the recycling area 10 is unlocked.

Referring to fig. 15, the driving part 130 of an embodiment includes a motor 133 and a cam 134; the cam 134 has at least one half-turn of a groove 135, the groove 135 passing through a distal end (i.e., the end distal from the axis of rotation of the cam) and a proximal end (i.e., the end proximal to the axis of rotation of the cam); the spacing member 110 is movably coupled to the recess 135 by a fastener 136 such that when the cam 134 is rotated from the proximal position to the distal position, the recess 135 drives the fastener 136 through its inner wall from the proximal end to the distal end of the cam 134 to move the spacing member 110 from the second position to the first position, and when the cam 134 is rotated from the distal position to the proximal position, the recess 135 drives the fastener 136 through its inner wall from the distal end to the proximal end of the cam 134 to move the spacing member 110 from the first position to the second position. Referring to fig. 16, it is still not limited to the case that the position limiting component 110 is implemented by the latch solution shown in fig. 12, when the cam 134 is in the remote position (i.e. the position shown in the figure), the latch 115 is in the first position under the driving of the fixing component 136, and the latch 115 extends into the positioning hole of the basket to lock the basket in the recycling area 10; when the cam 134 is in the proximal position, the latch 115 is in the second position, and the latch 115 does not extend into the locating hole of the basket, as driven by the fastener 136. The motor 133 drives the cam 134 to rotate, when the cam 134 rotates from the remote position to the near position, the fixing element 136 gradually changes from a rotating shaft far away from the cam 134 to a rotating shaft close to the cam 134, that is, the fixing element 136 moves from left to right as indicated in the figure, and accordingly, the latch 115 is also driven to gradually move from left to right, that is, the latch 115 moves from the first position to the second position, so that the latch 115 gradually retreats from a position extending into the positioning hole of the basket, and the basket in the recycling area 10 is unlocked; when the cam 134 rotates from the proximal position to the distal position, the fixing element 136 gradually changes from a position close to the rotation axis of the cam 134 to a position away from the rotation axis of the cam 134, i.e. the fixing element 136 moves from the right to the left as indicated in the figure, and accordingly, the latch 115 is gradually moved from the right to the left, i.e. the latch 115 moves from the second position to the first position, so that the latch 115 extends into the positioning hole of the basket to lock the basket in the recycling area 10.

Referring to fig. 17, in an embodiment where the driving member 130 is implemented by a cam (e.g., the driving member 130 in fig. 13 and 15), the driving member 130 may further include a detecting device, the detecting device includes a sensor sweeping piece 141 disposed on the cam and rotating with the cam, and the detecting device further includes a first sensor 142 and/or a second sensor 143. The first sensor 142 is disposed in such a manner as to be able to detect the sensor scanning piece 141 when the cam is in the remote position, and when the first sensor 142 detects the sensor scanning piece 141, it sends a signal, i.e., the above-mentioned basket locking signal, and the controller 40 detects the basket locking signal, and determines that the corresponding basket locking device 30 has correctly performed the locking operation. The second sensor 143 is configured to detect the sensor wiper 141 when the cam is in the close-range position, and the second sensor 142 also sends a signal when the sensor wiper 141 is detected, which may be referred to as a basket unlocking signal, and the sample injection system determines that the basket in the recovery area is unlocked after receiving the signal. Fig. 17 is a schematic diagram showing that the driving unit 130 of fig. 13 further includes a detection device.

Referring to fig. 18, the driving unit 130 of an embodiment may include a motor 137 and a pushing member 138, the motor 137 may drive the pushing member 138 to move between the long-range position and the short-range position, the pushing member may drive the limiting unit 110 to move from the second position to the first position during the process of moving from the short-range position to the long-range position, and the pushing member 138 may drive the limiting unit 110 to move from the first position to the second position during the process of moving from the long-range position to the short-range position. Referring to fig. 19, still taking the limiting component 110 as an example implemented by the latch solution shown in fig. 12, the pushing component 138 may be fixedly connected to the latch 115, so that the pushing component 138 and the latch move synchronously, and when the pushing component 138 moves from the short range position to the long range position, the latch 115 also moves from left to right in the drawing correspondingly, that is, the latch 115 moves from the first position to the second position, so that the latch 115 gradually moves out of the position extending into the positioning hole of the basket, and unlocks the basket in the recycling area 10; during the movement of the pusher 138 from the remote position to the near position, the latch 115 is moved from the right to the left in the figure accordingly, i.e. the latch 115 is moved from the second position to the first position, so that the latch 115 extends into the locating hole of the basket to lock the basket in the retrieval area 10.

Referring to fig. 20, in the embodiment where the driving part 130 is implemented by the pushing part 138, the driving part 130 may also include a detecting device, which includes a sensor wiper 144 disposed on the pushing part and moving with the pushing part, and a first sensor 145 and/or a second sensor 146. The first sensor 145 is disposed in such a manner as to detect the sensor wiper 144 when the pushing member 138 is in the remote position, and when the first sensor 145 detects the sensor wiper 144, it sends a signal, i.e., the above-mentioned basket locking signal, and the controller 40 detects the basket locking signal, and determines that the corresponding basket locking device 30 has correctly performed the locking operation. The second sensor 146 is configured to detect the sensor wiper 144 when the pushing member 138 is in the close-range position, and the second sensor 146 also sends a signal when the sensor wiper 144 is detected, which may be referred to as a basket unlocking signal, and the sample injection system determines that the basket in the recovery area is in the unlocked state after receiving the signal.

Of course, in order to make it clear to the user whether the basket of the recycling area is in the locked state or the unlocked state, an indicator lamp may be provided in the recycling area, and the indicator lamp may be displayed in a first state, for example, blinking, when the driving part 130 sends the basket locking signal, and in a second state, for example, long-lit, when the driving part 130 sends the basket unlocking signal.

The above is some descriptions of the basket locking device 30 of the present application, if there is a sample to be retrieved at present, the basket locking device 30 locks the basket of the retrieval area 10, so as to prevent the condition that the basket of the retrieval area 10 is taken away by the user when there is a sample to be retrieved, if there is no sample to be retrieved at present, the basket locking device 30 unlocks the basket of the retrieval area, and the user can take away the basket of the retrieval area 10.

Furthermore, the present invention incorporates a basket locking device 30 that can be used to further determine whether a basket is properly placed in the recovery area 10: although the basket in-place sensor is a sensor for detecting whether the basket is properly placed in the recovery area 10, in practice, the apparatus will perform a process, each sensor will have a triggering range, within this triggering range, the sensor is triggered, which inevitably brings about some errors, which may bring about a large error if the requirement for accuracy is very accurate, for example, when there is a small gap or a small foreign object between the basket and the retrieval, it is possible that the basket may still be triggered by the presence sensor, but the basket is actually slightly raised at this point, which may lead to two problems, one being that the inlet height of the basket is high for actually being correctly positioned, the sample is pushed back into the basket, the sample may not enter the basket, for example, the sample rack collides with the end face of the basket, and the collision or the sample topples over; secondly, as shown in fig. 3, when the basket is correctly placed in the recovery area, the anti-disengaging structure is still in a complete unlocking state, if the basket is not placed in place, the anti-disengaging structure is in a state between unlocking and locking, namely, the anti-disengaging structure is not in a complete unlocking state, and at the moment, the anti-disengaging structure can play a role in blocking a sample from entering the basket, so that the sample is toppled over when being pushed into the basket. Since when the basket locking device 30 is introduced, if the basket is not correctly placed in place, there is a high probability that the basket locking device 30 cannot correctly perform the locking action, and thus a basket abnormality is recognized, the sample introduction system does not dispatch the sample into the basket. The flow of controlling the basket locking device 30 to lock the basket of the recovery area 10 by the controller 40 will not be described by taking the basket locking device 30 shown in fig. 14 as an example.

The controller 40 controls the latch 115 of the basket locking device 30 to move from the second position to the first position and then determines whether a basket locking signal from the first sensor 142 is received.

If the controller 40 does not receive the basket locking signal from the first sensor 142, it indicates that the latch 115 of the basket locking device 30 has not moved completely to the first position, but has moved between the second position and the first position, which is very likely to result in the basket not being placed correctly in the retrieval area, for example, the basket is slightly raised, and the latch 115 cannot extend into the positioning hole of the basket when moving to the first position, but rather abuts against the end surface of the basket, and the latch 115 stops moving to the middle of the first position due to the blockage of the end surface of the basket, and the natural cam cannot move to the remote position, so that the first sensor 142 cannot detect the sensor wiper 141. In the above case, even if the basket is triggered at the presence sensor, since the first sensor 142 is not triggered, it is possible to recognize that the basket is not properly placed at the recovery area.

If the controller 40 receives the basket locking signal from the first sensor 142, it indicates that the latch 115 of the basket locking device is actually moved to the first position. If an in-place signal sent by the basket in-place sensor is detected at the moment, the basket is correctly placed in the recovery area; if the in-place signal from the in-place sensor is not detected, it indicates that either the basket is not in the recycling area or the latch 115 does not extend below the basket but extends below the basket, lifting the basket up causes the basket in-place sensor not to be triggered, and thus when the controller 40 receives the basket locking signal but does not receive the in-place signal, it indicates that either the basket is not in the recycling area or the basket in the recycling area is not properly placed.

From the above situation, it can be seen that the accuracy of determining that the basket is correctly placed in the recycling area can be greatly improved by combining the basket locking signal sent by the basket locking device and the in-place signal sent by the in-place sensor, and the basket is really correctly placed in the recycling area only when the basket locking signal and the in-place sensor can be detected at the same time.

Referring to fig. 21, an embodiment of the invention further provides a sample recovery method, which includes

steps

200 and 400.

Step 200: and judging whether a sample needs to be dispatched to a recovery area or not.

Step 400: and when judging that a sample needs to be dispatched to the recovery area, controlling the recovery of the sample. Referring to fig. 22, in one embodiment, the step 400 of controlling sample recovery includes

steps

410 and 420.

Step 410: the basket of the recovery area is locked. In one embodiment, the step 410 locks the basket of the recycling area by controlling the basket locking device to perform a locking action, so that referring to fig. 23, the step 410 may include steps 411 to 414.

Step 411: and judging whether the basket locking device correctly executes the locking action. When the basket locking device is judged not to execute the locking action correctly, go to step 412; if it is determined that the basket locking device does not perform the locking operation properly, the process proceeds to step 413.

Step 412 may include at least one of the following:

and generating prompt information for prompting the user that the basket in the recovery area is not locked correctly.

In a second mode, for the case that the sample injection system has one or more recovery areas, when the basket locking device is judged not to correctly execute the locking action, the samples needing to be dispatched to the recovery areas can be directly dispatched to the buffer area.

In a third mode, for a case where the sample injection system has a plurality of recovery areas, when it is determined that the basket locking device does not correctly perform the locking action, in addition to a measure of directly scheduling the samples to be scheduled to the recovery areas to the buffer area in the second mode, a mode of switching to another recovery area may be further adopted, specifically: when the basket locking device is judged not to correctly execute the locking action, whether the other recovery areas have available baskets is judged, if the other recovery areas have available baskets, the sample recovery is controlled for the recovery areas with the available baskets, for example, after the other recovery areas have available baskets, the step 410 is executed again. It is understood that if a plurality of recovery areas are determined to have a basket available, one of the recovery areas may be selected as the recovery area for receiving the sample to be recovered, for example, the recovery area closest to the outside of the sample injection system; and if the other recovery areas are judged to have no available baskets, scheduling the samples needing to be scheduled to the recovery areas to the buffer area. It should be noted that, the relationship between the second and third ways is yes, i.e. step 413 can only select one of them.

Step 413: and when the basket locking device is judged to correctly execute the locking action, continuously judging whether the basket is in place. If the basket is judged to be in place, the step 420 is performed, and if the basket is judged not to be in place, the step 414 is performed.

Step 414 may include at least one of the following:

and generating prompt information to prompt the user that the lifting basket in the recovery area is not in place.

In the second mode, for the case that the sample injection system has one or more recovery areas 10, when the basket is judged not to be in place, the samples needing to be dispatched to the recovery areas can be directly dispatched to the buffer area.

In a third mode, for a case that the sample injection system has a plurality of recovery areas 10, when the controller determines that the basket is not in place, in addition to a measure of directly scheduling the samples to be scheduled to the recovery areas to the buffer area in the second mode, a mode of switching to other recovery areas may be adopted, specifically: when the basket locking device is judged not to correctly execute the locking action, whether the other recovery areas have available baskets is judged, if the other recovery areas have available baskets, the sample recovery is controlled for the recovery areas with the available baskets, for example, after the other recovery areas have available baskets, the step 410 is executed again. It is understood that if a plurality of recovery areas are determined to have a basket available, one of the recovery areas may be selected as the recovery area for receiving the sample to be recovered, for example, the recovery area closest to the outside of the sample injection system; and if the other recovery areas are judged to have no available baskets, scheduling the samples needing to be scheduled to the recovery areas to the buffer area. It should be noted that, the relationship between the second and third ways is yes, i.e. step 413 can only select one of them.

Step 420: the samples are dispatched into a basket. As will be understood by those skilled in the art, dispatching the samples into the baskets herein refers to dispatching the samples that need to be dispatched to the recovery zone into the locked baskets.

Referring to fig. 24, in an embodiment, the step 400 of controlling sample recycling further includes

steps

401 and 402.

Step 401: before locking the basket in the recovery area, i.e., before proceeding to step 410, it is also determined whether there is a basket available in the recovery area. In one embodiment, step 401 may comprise: and judging whether the recovery area has an available basket when the sample is dispatched to the recovery area, and/or judging whether the recovery area has an available basket when the sample is dispatched to the inlet of the recovery channel. That is, step 401 may make a determination of whether a recovery zone has a basket available on at least one of these two occasions.

When it is determined that a basket is available in the recovery area, the process proceeds to step 410. In one embodiment, if there are a plurality of recovery areas, when it is determined that there are a plurality of recovery areas with a basket available, the recovery area closest to the outside of the apparatus among the recovery areas is selected as the recovery area for receiving the sample to be currently recovered.

When it is determined that the recovery area has no basket available, then step 402 is performed. Step 402 may employ at least one of the following:

and generating prompt information to prompt the user that no basket is available in the recovery area. For example, an audio file may be played through a speaker or a basket may be displayed through a display screen to prompt the user that the recycling area is not available; for another example, an indicator light may be provided in each recycling area 10 to indicate to the user that no basket is available in the recycling area by indicating the status of the indicator light, such as color, long bright, no bright, flashing, etc.

And secondly, dispatching the samples needing to be dispatched to the recovery area to the buffer area to wait for the available baskets to be placed in the recovery area.

Referring to fig. 25, in an embodiment, the step 400 of controlling sample recycling further includes the step 415:

after the sample needing to be dispatched to the recovery area is dispatched to the buffer area, monitoring whether an available basket exists in the recovery area, and once the basket available in the recovery area is monitored, controlling the sample to be recovered for the recovery area with the available basket, for example, jumping to the recovery area with the available basket to be executed from the step 410.

Referring to fig. 26, in an embodiment, the step 400 of controlling sample recycling further includes the step 430:

after the sample is dispatched into the basket at step 420, the basket is unlocked. Thus, the present application may lock the basket when it is not desired to have the user remove the basket (typically as is the case when there is a sample/rack that needs to be retrieved at the present time) so that the basket is not removed; and the basket can be unlocked in time under other conditions (such as the conditions that no sample/sample rack needs to be recycled at present) that can allow the user to remove the basket, so that the user can conveniently take the basket.
