Description

Sample introduction system and method for sample recovery

Technical field

The invention relates to a sampling system and a method for sample recovery.

Background technique

In-vitro diagnostic equipment refers to equipment that obtains clinical diagnostic information by detecting human samples (blood, body fluids, tissues, etc.) outside the human body, and then determines the disease or body function.

In in vitro diagnostic equipment, the sampling system (SDM) is mainly used to carry the sample rack put by the user, identify the barcode information of the sample rack and the sample tube on the sample rack, and dispatch and transfer the sample rack to a predetermined location. For example, the sample racks are scheduled to be transferred to the suction position, and the sample racks that have completed the suction are scheduled to be transferred to the recovery area.

In an existing sampling system, samples are carried in a basket. Both the loading area and the recycling area are placed in the basket. The basket in the loading area contains the sample to be sampled. The basket in the recycling area contains the recycled material. sample. From the perspective of the user, on the one hand, the user puts the samples to be injected into the basket in batches, and then puts the basket into the putting area; on the other hand, the user places the non-full basket in the recycling area to recover the samples. Remove the basket from the recycling area.

The existing sampling system often occurs when the sample to be recovered is being dispatched to the basket of the recycling area, but the basket is taken away by the user, which will cause a lot of bad consequences, for example, the sample being collected cannot be recovered. It is correctly dispatched to the recycle basket, for example, because the sample cannot be dispatched to the recycle basket, it stops at a certain position, which prevents the system sampling path, which causes the system injection to stop.

detailed description

The present invention will be further described in detail below through specific embodiments in combination with the accompanying drawings. In the different embodiments, similar elements are labeled with associated similar elements. In the following embodiments, many details are described so that the present application can be better understood. However, those skilled in the art can effortlessly realize that some of these features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to this application are not shown or described in the description. This is to prevent the core part of this application from being overwhelmed by excessive descriptions. For those skilled in the art, these are described in detail. The related operations are not necessary, they can fully understand the related operations according to the description in the description and the general technical knowledge in the field.

In addition, the features, operations, or features described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially swapped or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the description and drawings are only for clearly describing a certain embodiment, and are not meant to be a necessary order, unless otherwise stated that a certain order must be followed.

The serial numbers of components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any order or technical meaning. The terms “connection” and “connection” in this application include direct and indirect connections (connections) unless otherwise specified.

The injection system is a system for scheduling samples, completing sample injection and recovery. The scheduling unit of the injection system can be a sample rack. It should be noted that the sample rack can be a sample rack with multiple sample positions, that is, this sample rack can carry multiple samples, and the sample rack can also have only one sample position. The sample rack, that is, this sample rack can only carry one sample, which will be described in detail below.

The sample rack carries one or more sample tubes, and each sample tube contains a sample. The sampling system dispatches the sample racks as a unit. The sample racks are dispatched from the basket in the area to the aspiration position. Each sample on the rack is sucked and then provided to the mechanism for analyzing and measuring the sample, and the sample rack is finally dispatched to the basket in the recycling area for the user to remove with the basket.

Please refer to FIG. 1. In one embodiment of the injection system, one or more loading areas and one or more recycling areas may be included. The figure shows two loading areas and two side-by-side settings. Schematic of the recycling area. Of course, in some embodiments, the sampling system may include only the recovery area, but not the insertion area. Figure 1 (a) is a schematic diagram of the position scheduling of the sample rack from the loading area to the suction position: the loading area is used to place the basket, and the basket contains the samples to be injected. The sampling system will put the samples into the area. The rack is dispatched to the aspiration position for aspiration. Figure 1 (b) is a schematic diagram of the location scheduling of samples that have been sucked into the recycling area. The sample racks that have been sucked are scheduled from the suction position to the baskets in the recycling area. Users can remove the samples from the baskets in the recycling area. Recycle the sample rack. Of course, some failed sample racks and samples will also be dispatched to the basket in the recycling area.

The putting-in area and recycling area can be collectively referred to as the putting-in area. The above examples are all putting-in areas for samples to be injected. The recycling area has examples of recycling functions. In some other examples, the putting-in area and recycling area can be used. Combining two into one, there is such a storage area, which is used as both a loading area and a recycling area. When a sample or a sample rack needs to be dispatched to the basket of the storage area for recycling, we can also directly call this storage area as a recycling area, because this storage area has at least the function of a recycling area.

FIG. 2 is a schematic diagram of an actual mechanical structure of the basket. The placement area carries the basket, and the basket carries the sample rack or samples (the figure shows the basket directly carrying the sample rack). The user loads the basket into the sample rack, and then puts the basket into the putting area, so that the sampling system can finally dispatch the sample rack from the basket to the suction position; the user places the non-full basket in the recycling area, so The sampling system can finally push the sample rack after the suction into the basket located in the recycling area. After the basket is filled with the sample rack, the user can remove the basket from the recycling area. In order to prevent the sample rack from falling in the basket, the basket of one embodiment is provided with an anti-detachment structure near the end for pushing in and pushing out the sample rack to prevent the sample rack from falling out of the basket. When the basket is placed in the placing area At this time, the anti-dropout structure is triggered to be unlocked, as shown in Figure 3 (a); when the basket is removed from the placement area, the anti-dropout structure is gradually reduced from the unlocked state to the locked state, as shown in Figure 3 (b) .

It should be noted that, in the present invention, there are two ways to carry or place samples in the placement area, including direct loading of samples and indirect loading of samples. For example, the placement area can place multiple sample racks, and each sample rack carries multiple samples. For another example, the storage area can carry a basket that can be put in and taken out, and the basket is used to carry multiple samples. Similarly, the sample rack carries multiple samples, which may mean that the sample rack carries multiple sample tubes, and each sample container holds a sample. Similarly, the basket is used to carry multiple samples, which can also mean that the basket carries multiple samples by carrying multiple sample racks.

The sample introduction system of one embodiment introduces a basket lock device to lock the basket in the recovery area. If a sample rack needs to be collected, the basket in the recovery area is locked to prevent the basket in the collection area from being locked when the sample rack needs to be collected. When the user removes it, if there is currently no sample rack to be collected, the basket in the collection area is unlocked for the convenience of the user. Therefore, this application can lock the basket when the user does not want to remove the basket (typically when the sample / sample rack needs to be recycled currently), so that the basket cannot be removed; and in other cases where the user can remove the basket Unlock the basket in time (such as when there is no sample / sample rack that needs to be retrieved) to ensure that the user can easily take the basket.

This will be specifically described below.

Referring to FIG. 4, the sample injection system according to an embodiment includes a recovery area 10, a scheduling component 20, a basket locking device 30, and a controller 40. The recovery area 10 is used to carry a basket to receive a sample to be recovered. The scheduling component 20 is configured to schedule samples, for example, to achieve the samples carried on the scheduling sample rack by scheduling the sample rack. The basket locking device 30 is used to lock the basket placed on the recycling area 10 in the recycling area so that the user cannot take it away. Those skilled in the art can understand that if the sampling system includes a plurality of recovery areas 10, each recovery area can be configured with a basket locking device 30. It should be noted that FIG. 4 shows a case where there are two recovery areas 10, and those skilled in the art can understand that this is not used to limit the sampling system to include only two recovery areas 10, such as sample injection. The system may include one recycling area 10 or multiple recycling areas 10.

Referring to FIG. 5, the sample injection system according to an embodiment may further include a buffer area 11-for example, a buffer area 11 is provided in the sample injection system to assist in the scheduling of samples and to provide a transfer and buffer location for the samples. In one embodiment, the sampling system may include multiple layers. One layer is used to set the loading area and the recovery area, and the other layer is used to set the buffer area 11, which can save space and make the sampling system compact. . The buffer area 11 herein can store one or more sample racks. The size and size of the buffer area 11 in this article can be set according to the daily throughput or throughput of the sampling system. The buffer area 11 can be designed with many functions. Here are a few examples.

A specific function of the buffer area 11 may be a transfer station in the process of dispatching the sample rack from the loading area to the suction position for buffering the sample rack waiting for suction. Due to the existence of the buffer area 11, this causes a plurality of sample racks to be batch-scheduled to the buffer area 11 first, and then the scheduling unit 20 then schedules the sample racks to the sample suction position in order from the priority of the sample rack suction. For example, the priority of sample racks that require emergency treatment is higher than that of ordinary sample racks, and the sample racks that apply for testing first have higher priority than the sample racks that apply for testing later. A structure of the buffer area 11 is shown in FIG. 6. The buffer area 11 includes multiple channels, and each channel can place a sample rack. The scheduling unit 20 can schedule the sample racks buffered by the channel from any channel. For example, scheduling to the aspiration location or recycling area.

A specific function of the buffer area 11 may also be to buffer the sample racks that have been sucked, so that the samples on the sample racks can wait for their project test results at the buffer area 11. If the project test results are normal, the sample racks will be removed from The buffer area 11 is dispatched to the recovery area 10 for recycling. If the test result of the item is abnormal, it means that the corresponding sample on the sample rack needs to be retested. The sample rack will be dispatched from the buffer area 11 to the suction position, and the corresponding sample will be Samples are sucked for retesting items with abnormal test results. After that, the sample rack can continue to return to the buffer area 11 to wait for the test results of the retested items to be normal. It can also be directly dispatched to the recovery area, that is, no longer waiting for the retest Project test results. It should be noted that the abnormal test result of a sample of an item generally means that at least one test parameter result of the item is not within the preset range. If the test parameter result of the sample is within the corresponding preset range, the project test result is is normal.

The following is a description of the sample collection system's process for controlling sample recovery.

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

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

In order to ensure that there are available baskets in the recovery area 10, the controller 40 also introduces a judgment process in an embodiment. Specifically, the controller 40 controls the sample recovery including:

It is determined whether there are available baskets in the recycling area 10.

When it is determined that there are available baskets in the recycling area 10, the controller 40 controls the basket locking device 30 to lock the baskets in the recycling area 10, and controls the scheduling component 20 to dispatch the samples into the baskets. In an embodiment, for the case where the sampling system has multiple recovery areas 10, when the controller 40 determines that there are multiple recovery areas 10 with available baskets, it selects the recovery area 10 closest to the outside of the sampling system. 10—For example, the recycling area on the right in Figure 1 is closer to the outside of the sampling system than the recycling area on the left—as the recycling area that receives the samples to be recovered, so that the recycling area 10 on the outside of the sampling system can be installed preferentially. Full sample, easy for users to get.

When it is judged that there is no available basket in the recovery area 10-understandably, for the case where the sampling system has multiple recovery areas 10, it is judged that there is no available basket in the recovery area 10, which refers to all the recovery areas 10 in the injection system There are no available baskets on the top-the controller 40 may use at least one of the following methods:

In the first method, the controller 40 generates a prompt message to prompt the user that there is no available basket in the recycling area. For example, the sampling system can be set with speakers or display screens, playing audio files through the speakers, or using the display screen to remind the user that there is no available basket in the recycling area 10; for example, the sampling system can set an indicator light in each recycling area 10 , To remind the user that there are no available baskets in the recycling area through the status of the indicator light-such as color, long light, off light, flashing, etc.

In the second manner, the controller 40 controls the scheduling component 20 to schedule the samples that need to be scheduled to the recycling area 10 to the buffer area 11 to wait for the available baskets to be placed in the recycling area 10.

In one embodiment, the controller 40 determines whether there are available baskets in the recycling area 10, which can be determined at one or more timings. First, the specific path structure of the sampling system for dispatching samples to the recovery area will be described. Referring to FIG. 7, the sampling system includes a recovery channel 12, and the recovery channel 12 has an access port 12 a connected to the recovery area 10. It is understandable that if the sampling system has multiple recovery areas 10, for each recovery area 10, the recovery channel 12 has an access opening 12a connected to the recovery area 10; the recovery channel 12 also has an inlet 12b for the sample to enter the recovery channel 12. Therefore, for the samples that need to be dispatched to the recovery area 10, the scheduling component 20 first dispatches the samples to the inlet 12b of the recovery channel 12, and then dispatches the samples into the recovery channel 12 through the inlet 12b, and then passes through the passage 12a of the recovery channel 12, The samples are dispatched to the basket of the recycling area 10 corresponding to the entrance. The controller 40 determines whether there are available baskets in the recycling area 10, and the timing of the determination may be at least one of the following two:

The first opportunity is when the controller 40 determines that a sample needs to be dispatched to the recycling area 10; that is, when the controller 40 determines that a sample needs to be dispatched to the recycling area 10, the controller 40 then determines whether there is an available basket in the recycling area 10. For example, when the sample is sucked at the sample suction position, the controller 40 determines that the sample needs to be dispatched to the recovery area 10, and for example, when the sample is waiting in the buffer area 11 for its item test result, when it is judged that its item test result is normal, then The controller determines that the sample needs to be dispatched to the recycling area 10.

Opportunity two is when the sample is dispatched to the entrance 12b of the recovery channel 12; that is, when the sample is dispatched to the entrance 12b of the recovery channel 12 and is about to enter the recovery channel 12, the controller 40 determines whether the recovery area 10 is available at this time Of the basket.

It should be noted that the controller 40 controls the process of sample recovery. When it is determined that samples need to be dispatched to the recovery area, it can control the basket lock device 30 to lock the basket of the recovery area 10, and control the scheduling component 20 to dispatch the samples to the basket. Medium; when it is judged that a sample needs to be dispatched to the recycling area, the above-mentioned step of judging whether there is an available basket in the recycling area 10 is performed first, and then the subsequent process is performed according to the result of the judgment.

The following describes the process in which the controller 40 controls the basket locking device 30 to lock the basket in the recovery area 10.

The basket locking device 30 locks the basket of the recycling area 10 by performing a locking action. The controller 40 controls the basket locking device 30 to lock the basket of the recycling area 10 including:

The controller 40 determines whether the basket locking device 30 has performed the locking operation correctly.

When the controller 40 determines that the basket locking device 30 does not perform the locking action correctly, it can take at least one of the following ways:

In the first manner, the controller 40 generates prompt information for prompting the user that the basket of the recycling area is not locked properly. For example, the sampling system can be set with speakers or display screens, and audio files can be played through the speakers or the display screen can be used to prompt the user that the basket of the recycling area is not locked properly; for example, the sampling system can set an indicator light in each recycling area 10 , Remind the user that the basket in the recycling area is not locked properly by the state of the indicator-such as color, steady light, off light, flashing, etc.

Method 2: For a case where the sampling system has one or more recovery areas 10, when the controller 40 determines that the basket locking device 30 has not performed the locking action correctly, it can directly control the scheduling unit 20 to dispatch the samples that need to be scheduled to the recovery area to the cache. District 11.

Method 3: For the case where the sampling system has multiple recovery areas 10, the controller 40 judges that the basket locking device 30 does not perform the locking action correctly, except that in the second method, the scheduling component 20 is directly controlled to dispatch the samples to the recovery area. The measure to the buffer area 11 can also be taken to switch to other recovery areas 10, specifically: when the controller 40 determines that the basket locking device 30 has not performed the locking action correctly, it determines whether there are available baskets in other recovery areas 10, If it is determined that there are available baskets in other recycling areas 10, the controller 40 controls the sample recovery for the recycling areas 10 with available baskets. It is understandable that if it is determined that multiple recycling areas 10 have available baskets, the controller 40 One of the recycling areas 10 can be selected as the recycling area 10 for receiving the samples to be currently collected. For example, among these recycling areas 10, the recycling area 10 closest to the outside of the sampling system is selected. If it is judged that there is no available basket in the other recycling areas 10, The controller 40 controls the scheduling unit 20 to schedule the samples that need to be scheduled to the reclamation area to the buffer area 11. It should be noted that the relationship between mode 2 and mode 3 is OR, that is, the controller 40 can only choose one of them.

When the controller 40 judges that the basket locking device 30 performs the locking operation correctly, it continues to determine whether the basket is in place.

When the controller 40 determines that the basket is in place, the controller 40 performs the above-mentioned control and scheduling component 20 to schedule the samples into the basket.

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

In the first method, the controller 40 generates prompt information to prompt the user that the basket in the recycling area is not in place. For example, the sampling system can be set with speakers or display screens, playing audio files through the speakers, or using the display screen to prompt the user that the basket of the recycling area 10 is not in place; for example, the sampling system can set an indication in each recycling area 10 The light indicates that the basket of the recycling area 10 is not in place by the state of the indicator light, such as color, long light, no light, blinking, and the like.

Manner 2: For the case that the sampling system has one or more recovery areas 10, when the controller 40 determines that the basket is not in place, it can directly control the scheduling component 20 to dispatch the samples that need to be scheduled to the recovery area to the buffer area 11.

Method 3: For the case where the sampling system has multiple recovery areas 10, when the controller judges that the basket is not in place, in addition to adopting the second method to directly control the scheduling component 20 to dispatch the samples that need to be dispatched to the recovery area to the buffer area 11 Measures can also be taken to switch to other recycling areas 10, specifically: when the controller 40 determines that the basket is not in place, it determines whether there are available baskets in other recycling areas 10, and if it determines that there are available baskets in other recycling areas 10 For the recycling area 10 with available baskets, the controller 40 controls the sample recovery. Understandably, if it is determined that there are multiple recycling areas 10 with available baskets, the controller 40 may select one of the recycling areas 10 as the current receiving area. The recovery area 10 of the sample to be recovered, for example, the recovery area 10 of the recovery area 10 closest to the outside of the sampling system is selected; if it is determined that there are no available baskets in the other recovery areas 10, the controller 40 controls the scheduling component 20 to require scheduling The samples to the recycling area are dispatched to the buffer area 11. It should be noted that the relationship between mode 2 and mode 3 is OR, that is, the controller 40 can only choose one of them.

The above mentioned the case where the controller 40 dispatches the samples that need to be dispatched to the recycling area 10 to the buffer area 11, for example, when the controller 40 determines that there is no available basket in the recycling area 10, when it determines that the basket locking device 30 does not perform the locking action correctly When it is determined that the basket is not in place, measures can be taken to dispatch the samples that need to be dispatched to the recovery area 10 to the buffer area 11. The controller 40 of an embodiment controls the scheduling component 20 to schedule the samples that need to be dispatched to the recycling area to the buffer area 11, and then the controller 40 monitors whether there is an available basket in the recycling area 10-understandably, there are many In the case of each recycling area 10, the controller 40 monitors whether there are available baskets in the recycling area 10, and the monitoring object is all the recycling areas 10 in the sampling system. Once it is detected that there are available baskets in the recycling area 10, In the recovery area of the available basket, the controller 40 controls the sample recovery.

The process for the controller 40 to control the collection of samples in an embodiment may further include: the controller 40 unlocks the basket after controlling the scheduling component 20 to dispatch the samples to the basket in the recycling area.

It should be noted that, when the sampling system has multiple recovery areas, the current recovery area for recovering samples is switched from one recovery area to another, and the samples are scheduled to the buffer area for temporary storage and wait until There is a case where a recycling area for a basket is available. For this new recycling area that is used as a recovery sample, the controller 40 still performs a complete sample recovery process again when controlling the sample recovery, such as determining whether the current recycling area has The available baskets are used to lock the baskets in this recycling area, to determine whether the basket locking device in the recycling area performs the locking action correctly, and to determine whether the basket is in place after the basket locking device in the recycling area has performed the locking action correctly. Dispatch the basket after it is dispatched to the recycling area, etc .; Of course, those skilled in the art should understand that such a complete sample recycling process, as in some embodiments described herein, includes some process steps. It can be omitted.

The recycling area mentioned in this article has a usable basket, which means that the basket is placed in the recycling area: the basket is not full of samples and is correctly placed in the recycling area. The basket is not full of samples indicating that the basket can continue to load and recycle samples; the basket is correctly placed in the recycling area, and the samples can be correctly dispatched to the basket in the recycling area. If the basket is not properly placed in the recycling area, For example, when the basket is placed in the recycling area, the corner is tilted, so that the sample may fall when it is dispatched to the basket in the recycling area. In one embodiment of the present invention, a basket presence sensor is introduced to detect whether the basket in the recycling area is correctly placed, and a basket full load sensor is introduced to detect whether the basket in the recycling area is fully loaded. Specifically, the basket in-position sensor is set in the recycling back, and is used to generate an in-position signal when the basket is correctly placed in the recycling area. The basket full load sensor is set in the recycling area, and is used when the basket in the recycling area is full of samples. When full load signal is generated. Therefore, when the controller 40 detects the in-position signal and does not detect the full-load signal, it determines that there is a available basket in the recycling area; when the controller 40 detects the in-position signal, it determines that the basket in the recycling area is correctly placed in the recycling area, that is, Judge the basket in place.

Please refer to FIG. 8 for a partial structural schematic diagram of the recovery system 10 provided with a basket locking device 30. Specifically, two recovery areas 10 arranged side by side are shown, one of which has a basket and the other has no basket. It can be seen from the recycling area 10 where the basket is not placed that it is provided with a basket presence sensor. Only when the basket is correctly placed in the recycling area 10, the basket presence sensor will be triggered to generate an in-position signal. If there is a gap or a foreign object between the basket and the recovery area, the basket may not trigger the basket presence sensor at this time, so the controller 40 determines that the current basket is not in place.

The above are some descriptions of the sample collection system for controlling sample recovery. The following describes the basket locking device 30 of the sample collection system.

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

The limiting member 110 can reciprocate between the first position and the second position. When the limiting member 110 is in the first position, the basket can be locked, that is, the user cannot remove the basket from the recycling area 10 at this time. When the position component 110 is in the second position, the basket is not locked, that is, the basket is in an unlocked state in the recycling area 10, and the user can take the basket from the recycling area 10 at this time.

There are various implementation manners of the limiting component 110, which are described below by way of example.

Referring to FIG. 10, the limiting member 110 according to an embodiment may include a hook claw 111 and a fixing member 112 disposed on the sampling system. For example, the fixing member 112 may be disposed below the recovery channel 12 connected to the recovery region 10. The pawl 111 is provided in the fixing member 112 so as to be movable between a first position and a second position. The basket has a limiting structure that cooperates with the hook claw 111, so that when the hook 111 is in the first position, it can cooperate with the limiting structure of the basket to lock the basket in the recycling area 10, and the user cannot remove the basket from the recycling area 10. When the hook 111 is in the second position, it does not act on the limiting structure of the basket, so that the basket is in an unlocked state, and the user can remove the basket from the recycling area 10. It should be noted that the hook claw 111 in FIG. 10 can be rotated with the fixed member 112 as an axis in the direction shown by the arrow in the figure. When the movement is moved to the first position, the basket is locked, and when it is moved to In the second position, the basket is unlocked. In Fig. 10, the edge of the basket itself will be used as the limit structure of the basket to cooperate with the hook 111. Fig. 10 shows that the hook 111 moves to the first position to lock the basket. In addition, the partial structure of the injection system is shown in FIG. 10, which includes two recovery areas arranged side by side, and one of the recovery areas 10 is placed with a basket.

Referring to FIG. 11, the limiting member 110 according to an embodiment may include a pressing block 113 and a fixing member (not shown in the figure) provided in the sampling system. For example, the fixing member may be provided in a recycling area connected to the recycling area 10. Below the channel 12. The pressing block 113 is provided on the fixed member in a manner capable of moving between the first position and the second position. When the pressing block 113 is in the first position, it can hold the basket in the recovery area 10, so that the basket cannot be removed by the user. When the pressing block 113 is in the second position, the basket in the recovery area 10 is not pressed, 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 in the direction indicated by the arrow in the figure. When the downward movement reaches the first position, the basket is locked, and when the upward movement reaches the second position, the basket is unlocked. ; Figure 11 shows the schematic diagram of the block 113 moving to the first position to lock the basket; In addition, Figure 11 shows the partial structure of the sampling system, including two recovery areas 10 arranged side by side, one of which is placed in the recovery area 10 The situation of the basket.

Referring to FIG. 12, the limiting member 110 according to an embodiment may include a latch 115 and a fixing member 116 provided in the sampling system. For example, the fixing member 116 may be provided below the recovery channel 12 connected to the recovery region 10. The latch 115 is provided to the fixed member 116 so as to be movable between a first position and a second position. The basket has a positioning hole that cooperates with the latch 116. When the bolt 115 is in the first position, the bolt 115 can be extended into the positioning hole of the basket to lock the basket in the recovery area 10 so that the basket cannot be removed by the user. When the bolt 116 is in the second position, the bolt is not It extends into the positioning hole of the basket, so that the basket is not locked, or the basket is in an unlocked state, and the user can remove the basket from the recycling area 10.

The driving component 130 is used to drive the limiting component 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, thus completing the unlocking operation of the basket of the recycling area 10; the driving member 130 drives the limiting member 110 from the second position to the first Position, thus completing the action of locking the basket of the recovery area 10. Therefore, the driving member 130 drives the limiting member 110 from the second position to the first position is defined as a locking action of the basket locking device.

In one embodiment, a basket locking device 30 may be provided in each recovery area 10 of the sampling system. In this way, when a sample in the sampling system currently needs to be dispatched to the basket of the recovery area, the driving unit 130 drives the limit unit 110 To the first position, thereby locking the basket of the recycling area, so that the sample is smoothly dispatched to the basket of the recycling area 10. After the samples are successfully dispatched to the basket of the recycling area 10, or when no samples currently need to be dispatched to the basket of the recycling area 10 in the sampling system, the driving part 130 may drive the limit part 110 to the second position, The basket in the recycling area 10 is unlocked so that the user can remove the basket. In order to facilitate the sampling system to determine whether the sample rack to be recycled can be dispatched to the basket of the recycling area, the basket lock device of an embodiment sends a basket lock signal when the driving unit 130 drives the limit unit 110 to the first position. When the controller 40 receives this basket lock signal, it determines that the basket lock device 30 has correctly performed the lock operation.

There are various implementation manners of the driving component 130, which are described below by way of example.

Referring to FIG. 13, the driving component 130 according to an embodiment may include a motor 131, a cam 132, and a reset member (not shown). It should be noted that, for the embodiment in which the driving member 130 is implemented by a cam in this article, when the end of the cam near the cam rotation shaft moves to the limit member 110, the cam is said to be in a short range. When the cam is far from the cam rotation shaft, When one end moves close to the limiting member 110, the cam is said to be in a remote position. The motor 131 can drive the cam 132 to rotate with the shaft to be in the remote position or the short-range position. When the cam 132 is rotated from the short-range position to the remote position, it can drive the limiting member 110 from the second position to the first position. When the position is turned to the short-range position, the reset member works at this time, and the position limiting member 110 can be reset from the first position to the second position. In one embodiment, the reset member can be implemented by a reset spring. Please refer to FIG. 14. It may be exemplified that the limiting member 110 is implemented by the latch scheme shown in FIG. 12 as an example. When the end of the cam 132 against the latch 115 is the short-range position of the cam 132 (that is, the end near the cam rotation shaft) At this time, the latch 115 is in the second position, and the latch 115 does not protrude into the positioning hole of the basket. When the end of the cam 132 against the latch 115 is the remote position of the cam 132 (that is, the end away from the cam rotation shaft), at this time 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 recovery area 10. FIG. 14 shows a case where the end of the cam 132 against the latch 115 is the remote position of the cam 132, that is, the case where the cam 132 is in the remote position. The motor 131 drives the cam 132 to rotate. When the end of the cam 132 against the latch 115 is changed from the near position of the cam 132 to the remote position of the cam 132, the latch 115 is moved from right to 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 and locks the basket in the recovery area 10; when the end of the cam 132 against the bolt 115 is changed from the remote position of the cam 132 to When the cam 132 is in the short-range position, the latch 115 moves from left to right as indicated in the figure 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 extends from the extension to the basket. The position in the positioning hole of the exit exits, and the basket of the recovery area 10 is unlocked.

Referring to FIG. 15, the driving component 130 of an embodiment includes a motor 133 and a cam 134; the cam 134 has a groove 135 of at least half a circle, and the groove 135 passes through the remote end of the cam (that is, the end away from the cam rotation shaft) and the The end of the cam (that is, the end near the rotation axis of the cam); the limiting member 110 is movably connected to the groove 135 through a fixing member 136, so that when the cam 134 rotates from the short range to the remote position, the groove 135 passes through The inner wall driving fixture 136 is moved from the near end of the cam 134 to the remote end, thereby driving the limiting member 110 to move from the second position to the first position. When the cam 134 is rotated from the remote position to the near position, the groove 135 passes The inner wall driving fixture 136 is moved from the remote end of the cam 134 to the short range end, thereby driving the position-limiting member 110 from the first position to the second position. Please refer to FIG. 16. It may be exemplified that the limiting member 110 is implemented by using the latch scheme shown in FIG. 12 as an example. When the cam 134 is in a remote position (ie, the position shown in the figure), driven by the fixing member 136, The latch 115 is in the first position, the latch 115 extends into the positioning hole of the basket and locks the basket in the recovery area 10; when the cam 134 is in the short range position, driven by the fixing member 136, the latch 115 is in the second position, the latch 115 did not reach into the positioning hole of the basket. The motor 133 drives the cam 134 to rotate. When the cam 134 rotates from the remote position to the short range position, the fixing member 136 will gradually change from the rotation axis of the cam 134 to the rotation axis of the cam 134, that is, the fixing member 136 will change from the position shown in the figure. The marked movement from left to right accordingly also drives the bolt 115 to move from left to right, that is, the movement of the bolt 115 from the first position to the second position, so that the bolt 115 gradually extends into the position of the positioning hole of the basket. Exit, unlock the basket in the recovery area 10; when the cam 134 rotates from the short-range position to the remote position, the fixing member 136 will gradually change from the rotation axis near the cam 134 to the rotation axis far from the cam 134, that is, the fixing member 136 Will move from right to left as indicated in the figure, and accordingly, the pin 115 will be gradually moved from right to left, that is, the pin 115 moves from the second position to the first position, so that the pin 115 extends into the positioning of the basket The basket is locked in the recovery area 10 in the hole.

Referring to FIG. 17, in an embodiment in which the driving member 130 is implemented by a cam (such as the driving member 130 in FIGS. 13 and 15), the driving member 130 may further include a detection device including a detection device disposed on the cam and following The cam rotation sensor scans the blade 141, and the detection device further includes a first sensor 142 and / or a second sensor 143. The first sensor 142 is arranged in such a manner that the sensor swipe 141 can be detected when the cam is in the remote position. When the first sensor 142 detects the sensor swipe 141, it sends out a signal, that is, the above-mentioned basket lock signal, and the controller 40 detects When this basket lock signal is reached, it is determined that the corresponding basket lock device 30 has correctly performed the locking action. The second sensor 143 is set in a manner that the sensor swipe 141 can be detected when the cam is in the short range position. When the second sensor 142 detects the sensor swipe 141, a signal is also issued, and this signal can be referred to as a basket unlock signal. After receiving the signal, the sampling system judges that the basket in the recovery area is unlocked. It should be noted that FIG. 17 is a schematic diagram showing that the driving component 130 of FIG. 13 further includes a detection device.

Referring to FIG. 18, the driving part 130 according to an embodiment may include a motor 137 and a pushing member 138. The motor 137 can drive the pushing member 138 to move between the remote position and the short range position, and the push member moves from the short range to the remote position. During the process, the limit member 110 is driven to move from the second position to the first position, and the pushing member 138 is driven to move the limit member 110 from the first position to the second position during the process from the remote position to the short range position. Referring to FIG. 19, it may be still taken as an example that the limiting member 110 is implemented by using the bolt scheme shown in FIG. 12. The pushing member 138 may be fixedly connected to the bolt 115. In this way, the pushing member 138 and the bolt move synchronously. 138 During the movement from the short-range position to the remote position, the bolt 115 will also move from left to right in the figure, that is, the bolt 115 moves from the first position to the second position, so that the bolt 115 gradually extends from the extension to the basket. The position in the positioning hole is pulled out to unlock the basket of the recovery area 10. When the pusher 138 moves from the remote position to the short range position, the latch 115 will also move from right to left in the figure, that is, 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 and locks the basket in the recovery area 10.

Referring to FIG. 20, in an embodiment in which the driving member 130 is implemented by the pushing member 138, the driving member 130 may also include a detection device, and the detecting device includes a sensor swipe disposed on the pushing member and moving with the pushing member. 144. The detection device further includes a first sensor 145 and / or a second sensor 146. The first sensor 145 is provided in a manner that the sensor swipe 144 can be detected when the pusher 138 is in a remote position. When the first sensor 145 detects the sensor swipe 144, it sends out a signal, that is, the above-mentioned basket lock signal. The controller 40 detects this basket lock signal, and determines that the corresponding basket lock device 30 has correctly performed the locking action. The second sensor 146 is set in a manner that the sensor swipe 144 can be detected when the pusher 138 is in the short range position. When the second sensor 146 detects the sensor swipe 144, it also sends a signal. This signal can be called a basket. Unlocking signal. After receiving the signal, the sampling system judges that the basket in the recycling area is unlocked.

Of course, in order to enable the user to clearly understand whether the basket of the recycling area is locked or unlocked, an indicator light can be set in the recycling area. When the driving unit 130 sends a basket lock signal, the indicator light is displayed in the first state. For example, blinking, when the driving component 130 sends a basket unlock signal, the indicator light is displayed in the second state, for example, it is constantly on.

The above are some descriptions of the basket locking device 30 of the present application. If a sample needs to be retrieved currently, the basket locking device 30 locks the basket of the recycling area 10 to prevent the basket of the recycling area 10 from being taken by the user when a sample needs to be recycled. If there is no sample to be recovered at present, the basket locking device 30 unlocks the basket in the recycling area, and the user can remove the basket in the recycling area 10.

Not only that, the introduction of the basket locking device 30 in the present invention can be used to further determine whether the basket is correctly placed in the recycling area 10: Although the basket in-position sensor is a sensor used to detect whether the basket is correctly placed in the recycling area 10, the actual device implementation process When each sensor has a trigger range, the sensor will be triggered within this trigger range, which will inevitably bring some errors. If it is required to be very accurate, this error may cause a large Wrong, for example, when there is a small gap or a small foreign object between the basket and the recycling, it is possible that the basket in-position sensor will still be triggered at this time, but the basket is actually slightly elevated at this time, which may cause two The problem is that the height of the entrance of the basket is high when it is actually placed in place. When the sample is pushed back into the basket, the sample may not enter the basket-for example, the sample rack hits the end surface of the basket and a collision occurs. Or the sample is dumped; the second is that the basket anti-dropout structure shown in Figure 3 is correctly placed in the recycling area The anti-dropout structure is still completely unlocked. If it is not placed in place, the anti-dropout structure is in a state between unlocked and locked, that is, not fully unlocked. At this time, the anti-dropout structure will prevent the sample from entering the basket. Effect, causing the sample to tip over if it is forced into the basket. When the basket locking device 30 is introduced, if the basket is not placed in place, there is a high probability that the basket locking device 30 cannot perform the locking action correctly, thereby identifying an abnormal basket, and the sampling system does not dispatch samples to the basket. Taking the basket locking device 30 shown in FIG. 14 as an example, the controller 40 controls the basket locking device 30 to lock the basket in the recovery area 10 for explanation.

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 lock signal from the first sensor 142 is received.

If the controller 40 does not receive the basket lock signal from the first sensor 142, it means that the latch 115 of the basket lock device 30 has not completely moved to the first position, but moved between the second position and the first position. This is most likely that the basket is not properly placed in the recovery area-for example, the basket is slightly raised, causing the bolt 115 to not enter the positioning hole of the basket when it moves to the first position, but it is against the end surface of the basket, causing the bolt During the movement of 115 to the first position, it stopped due to the blocking of the end surface of the basket. At this time, the natural cam cannot move to the remote position, so that the first sensor 142 cannot detect the sensor blade 141. In the above case, even if the basket in-position sensor is triggered, since the first sensor 142 is not triggered, it can be identified that the basket is not correctly placed in the recycling area.

If the controller 40 receives the basket lock signal from the first sensor 142, it indicates that the latch 115 of the basket lock device has actually moved to the first position. If the in-position signal from the in-position sensor is also detected at this time, the in-position signal is correctly placed in the recycling area; if the in-position signal from the in-position sensor is not detected, it indicates that either there is no in-recycling area in the recovery area. Either the bolt 115 does not reach the positioning hole of the basket, but extends below the basket, and lifts the basket, resulting in the in-position sensor of the basket not being triggered, so the controller 40 receives the basket lock signal but cannot receive it. When the signal is in place, it means that either there is no basket in the recycling area or the basket in the recycling area is not properly placed.

It can be seen from the above situation that the basket lock signal from the integrated basket lock device and the in-position signal from the in-situ sensor can greatly improve the accuracy of judging that the basket is correctly placed in the recycling area, and the basket can only be detected at the same time The lock signal and the presence sensor indicate that the basket is really properly placed in the recovery area.

Referring to FIG. 21, an embodiment of the present invention further provides a method for sample recovery, including

steps

200 and 400.

Understandably, if it is determined that multiple recycling areas have available baskets, one of the recycling areas may be selected as the recycling area for receiving the samples to be currently collected, for example, the recycling area closest to the outside of the sampling system among these recycling areas may be selected; If it is determined that there are no available baskets in other recycling areas, the samples that need to be scheduled to the recycling area are scheduled to the buffer area. It should be noted that the relationship between mode 2 and mode 3 is OR, that is, step 413 can only choose one of them.

Step 420: Schedule the samples into the basket. A person skilled in the art can understand that scheduling a sample into a basket here means scheduling a sample that needs to be scheduled to a recycling area into a locked basket.

Referring to FIG. 24, in an embodiment, step 400 for controlling sample recovery further includes

steps

401 and 402.
