The embodiment of the application provides a sample detection control method, a sample detection system and control equipment.

The sample detection system comprises a sample introduction mechanism, a sample analyzer and a control device, wherein the control device is in communication connection with the sample introduction mechanism and the sample analyzer, the sample introduction mechanism comprises a feeding track 101, a scanning device 102 and a loading platform 103 arranged on one side of the feeding track, and the sample analyzer comprises a first detector 104 and a second detector 105 arranged on the other side of the feeding track 101; the first detection item category executed by the first detector 104 is different from the second detection item category executed by the second detector 105.
The feeding track 101 is used for driving the sample rack to move towards the direction of the sample analyzer. For example, the feeding track 101 may be a conveyor belt, which may run along the direction of the first detector 104 moving towards the second detector 105, or along the direction of the second detector 105 moving towards the first detector 104. The first detecting instrument 104 and the second detecting instrument 105 are respectively configured to perform detection on the sample to be detected in a first detection item category and a second detection item category, where the first detection item category and the second detection item category are different from each other. The first detector 104 and the second detector 105 may be medical field detection equipment, for example, they may be blood analyzers for detecting blood composition. Here, the first test item category may be a blood routine test item (test pattern of any combination of CBC, DIFF, and RET), and/or a separate specific protein test item (test pattern of any combination of SAA, CRP, PCT, IL-6); the second assay item category may be an immunoassay item and/or a glycated assay item (GHB). In this regard, the first detection item category and the second detection item category are not limited in the embodiments of the present application.

The scanning device 102 may be a radio frequency card reader or a code scanner. If the scanning device 102 is a code scanner, correspondingly, a label can be set on the sample rack, the label includes a unique barcode or two-dimensional code, basic information of the sample rack can be obtained by scanning the barcode or the two-dimensional code on the label, and the basic information includes related information such as the number of samples to be detected on the sample rack, and the types of detection items included in the samples to be detected. The control device can be a computer or a mobile phone and other devices with communication control functions.
Also shown in fig. 1 is an unloading platform 106, said unloading platform 106 being provided on the same side of the loading platform 103 with respect to the feed track 101 for removing the specimen rack loaded with specimens to be tested from the feed track 101.

Therefore, for the sample detection system which is used for completing sample sending of the cascading sample analyzer comprising the plurality of detectors by the same sample feeding mechanism, if the types of detection items contained in the plurality of detectors are different, the sample feeding mechanism can carry out sample sending detection on the plurality of detectors by taking the sample rack as a unit, so that the requirement that the sample rack is carried to move back and forth among the plurality of detectors can be reduced, and the loss and consumption of a feeding track can be reduced; in addition, the sample feeding mechanism can load two rows of sample racks in the same time period so that the first detector and the second detector work simultaneously, and therefore the utilization efficiency of the first detector and the second detector is improved, and the detection efficiency of the sample racks is further improved.
Referring to fig. 2, a flowchart of a sample detection control method applied to the sample detection system shown in fig. 1 according to an embodiment of the present disclosure is shown. Here, the first detection item category executed by the first detection instrument is completely different from the second detection item category executed by the second detection instrument. The sample detection control method comprises the following steps:
s201: and controlling the sample feeding mechanism to load a first sample rack loaded with a sample to be detected from the loading platform to the feeding track.
In one example, a first sensor is provided on the first detector, and the first sensor is in communication with the control device. When the first sensor detects that the first detector does not contain the unexecuted previous sample rack, the control device controls the sample feeding mechanism to load the first sample rack loaded with the sample to be detected from the loading platform to the feeding track. The preceding sample rack is a sample rack that has been on the feed track before a specified time within a set time period, and the first sample rack is a sample rack that is being loaded from the loading platform into the feed track at a specified time within a set time period.
S202: and driving the first sample rack to move towards the direction of the sample analyzer through the feeding track, and obtaining a sample identifier obtained by scanning the running sample to be detected by the scanning device.
Here, the first sample rack may contain a plurality of samples to be detected. The sample identification can refer to basic information of the sample rack, and the basic information comprises the number of the samples to be detected on the sample rack, the detection item categories contained in the samples to be detected and other related information. The item category to be detected may refer to an item category to be detected in each sample to be detected. In one example, the feeding track drives the first sample rack to move towards the direction of the sample analyzer, the scanning device scans the sample to be detected which passes through the feeding track to obtain a sample identifier and sends the sample identifier to the control device, and the control device obtains the sample identifier.
S203: and judging whether the sample to be detected on the first sample rack contains the first detection item category of the first detector or not according to the sample identification.
In one example, the control device obtains, according to the sample identifier, a detection item category corresponding to the sample identifier from a database, and also obtains a first detection item category of the first detector, and determines whether the sample to be detected on the first sample rack includes the first detection item category of the first detector.
S204: if the to-be-detected sample on the first sample rack contains the first detection item type of the first detector, controlling the feeding track to convey the first sample rack to the first sampling position corresponding to the first detector, so that the first detector can extract the corresponding to-be-detected sample at the first sampling position to perform detection of the first detection item type.
The sampling position comprises two conditions, namely a venous blood blending hand grab grabs the test tube reaching the sampling position into a detector for sample suction and collection; in the second case, a test tube containing a liquid to be detected is transported to a sampling site, and a sampling needle of the detector descends after moving out in the front-back direction/Y direction to directly perform puncture and suction of a sample. The first sampling position in the embodiment of the application can be a position point where the first detector can smoothly suck the sample to be detected on the sample rack. In one example, the control device determines that the to-be-detected sample on the first sample rack contains a first detection item category of the first detector, and controls the feeding track to convey the first sample rack towards a first sampling position corresponding to the first detector, so that the first detector can extract the corresponding to-be-detected sample at the first sampling position to perform detection of the first detection item category.
S205: after the sample to be detected on the first sample rack is executed in the first detection item category of the first detector, whether the sample to be detected on the first sample rack contains the second detection item category of the second detector is judged.
In one example, after the sample to be detected on the first sample rack is executed in the first detection item category of the first detector, the first detector sends a signal of execution completion to a control device. And the control equipment acquires the second detection item type of the second detector from the database according to the execution completion signal, and judges whether the to-be-detected sample on the first sample rack further comprises the second detection item type of the second detector.
S206: and if the to-be-detected sample on the first sample rack contains a second detection item type of the second detector, controlling the feeding track to convey the first sample rack towards a second sampling position corresponding to the second detector, so that the second detector extracts the corresponding to-be-detected sample at the second sampling position to perform detection of the second detection item type, controlling the sample introduction mechanism to load the second sample rack loaded with the to-be-detected sample from the loading platform to the feeding track, returning to the step of driving the first sample rack to move towards the sample analyzer through the feeding track, and acquiring a sample identifier obtained by scanning the to-be-detected sample by the scanning device.
Here, the second sampling position may refer to a position point at which the second detector can smoothly extract the sample to be detected on the sample rack. In one example, the control device determines that the to-be-detected sample on the first sample rack contains a second detection item category of the second detector, and controls the feeding track to convey the first sample rack to a second sampling position corresponding to the second detector, so that the second detector can extract the corresponding to-be-detected sample at the second sampling position to perform detection of the second detection item category. And simultaneously, controlling the sample introduction mechanism to load a second sample rack loaded with a sample to be detected from the loading platform to the feeding track by the control equipment, returning to the step of driving the first sample rack to move towards the sample analyzer through the feeding track, and acquiring a sample identifier obtained by scanning the sample to be detected by the scanning device. Wherein the second sample rack is a sample rack that enters the feed track after the first sample rack within a set period of time. It should be noted that, after the second sample rack, a third sample rack and a fourth sample rack may also sequentially enter the feeding track, and after the third sample rack and the fourth sample rack sequentially enter the feeding track, the third sample rack and the fourth sample rack are replaced with the first sample rack, and the step of driving the first sample rack to move toward the sample analyzer through the feeding track to obtain a sample identifier obtained by scanning the running sample to be detected by the scanning device is repeatedly performed until the detection of all the test tube racks is completed.
In the sample detection control method provided in the above embodiment of the present application, whether the sample to be detected on the first sample rack includes the first detection item category of the first detector is determined; if the to-be-detected sample on the first sample rack contains a first detection item type of the first detector, controlling the feeding track to convey the first sample rack to a first sampling position corresponding to the first detector, so that the first detector can extract the corresponding to-be-detected sample at the first sampling position to perform detection of the first detection item type; after the sample to be detected on the first sample rack is executed in the first detection item category of the first detector, judging whether the sample to be detected on the first sample rack contains the second detection item category of the second detector; if the sample to be detected on the first sample rack comprises a second detection item type of the second detector, controlling the feeding track to convey the first sample rack to a second sampling position corresponding to the second detector, so that the second detector can extract the corresponding sample to be detected at the second sampling position to execute detection of the second detection item type, and controlling the sample feeding mechanism to load the second sample rack loaded with the sample to be detected from the loading platform to the feeding track. Therefore, for the sample detection system which is used for completing sample feeding of the cascading sample analyzer comprising the plurality of detectors by the same sample feeding mechanism, if the types of detection items contained in the plurality of detectors are different, the sample feeding mechanism can carry out sample feeding detection on the plurality of detectors by taking the sample rack as a unit, the requirement that the sample rack is carried to move back and forth among the plurality of detectors is reduced, and the loss and consumption of a feeding track can be reduced; in addition, the sample feeding mechanism can load two rows of sample racks in the same time period so that the first detector and the second detector work simultaneously, and therefore the utilization efficiency of the first detector and the second detector is improved, and the detection efficiency of the sample racks is further improved.
In some embodiments, the obtaining a sample identifier obtained by scanning the sample to be detected by the scanning device includes: and scanning the first sample rack which runs by the scanning device to obtain sample identifications of the plurality of samples to be detected which are arranged in the first sample rack in sequence.
Generally, the number of the samples to be detected on the first sample rack is multiple, and each sample to be detected has a corresponding label. The label comprises a unique bar code or two-dimensional code, basic information corresponding to a sample to be detected can be obtained by scanning the bar code or the two-dimensional code on the label, and the basic information comprises related information such as detection item types and the like contained in the sample to be detected. Therefore, when the scanning device scans the samples to be detected on the first sample rack, the scanning device can respectively scan each sample to be detected on the first sample rack in sequence so as to ensure that the samples to be detected on the first test tube rack can make accurate judgment on the detection item category before sample detection. The control device is electrically connected with the scanning device, and therefore, the obtaining of the sample identifiers of the plurality of samples to be detected, which are installed in the first sample rack, by scanning the first sample rack running through the scanning device by the scanning device sequentially means: the control equipment obtains the first sample frame which is scanned by the scanning device and runs through the scanning device, and the sample identifications of the plurality of samples to be detected which are arranged in the first sample frame are obtained in sequence.
According to the sample detection control method provided by the embodiment of the application, before the first sample rack is controlled to detect the samples to be detected, the sample identifications of the multiple samples to be detected, which are arranged in the first sample rack, are sequentially obtained through the scanning device, so that not only can the accurate judgment of the detection item types of the samples to be detected on the first sample rack be ensured before the sample detection is carried out, but also the back and forth movement of the first sample rack between the scanning device and the first sampling position can be reduced, and the loss consumption of a feeding track is reduced.
In some embodiments, before the determining whether the sample to be tested on the first sample rack comprises the second testing item category of the second testing instrument, the method further comprises: judging whether at least one of the samples to be detected on the first sample rack meets a re-detection condition according to a detection result of the first detector on the samples to be detected on the first sample rack; and if at least one sample to be detected meets the retest condition, controlling the feeding track to convey the corresponding sample to be detected to the first sampling position so that the first detector can retest the sample to be detected.
Here, the satisfaction of the retest condition may mean that the detection result of the sample to be detected exceeds a preset value. The determining, according to the detection result of the first detector on the samples to be detected on the first sample rack, whether at least one of the samples to be detected on the first sample rack meets the retest condition may be: and the control equipment acquires detection results corresponding to the samples to be detected on the first sample rack from the first detector and judges whether each detection result exceeds a preset value. If at least one of the samples to be detected meets the retest condition, controlling the feeding track to convey the corresponding sample to be detected to the first sampling position, so that the first detector performs the retest on the sample to be detected may refer to: if the detection result corresponding to at least one sample to be detected exceeds a preset value, the feeding track is controlled to convey the corresponding sample to be detected to a first sampling position, so that the first detector can perform retesting on the sample to be detected.
In the sample detection control method according to the embodiment of the application, before the feeding track is controlled to convey the first sample rack to the second sampling position corresponding to the second detector, so that the second detector extracts the sample to be detected at the second sampling position and performs detection of a corresponding detection item category, whether the first sample rack needs to be retested or not is determined by judging whether at least one of the samples to be detected on the first sample rack meets a retest condition when performing detection on the first detector, so that the possibility of repeatedly loading and removing the same sample rack is avoided, and the detection efficiency of the sample to be detected on the sample rack is improved.
In some embodiments, the sample injection mechanism further comprises an unloading platform, and the unloading platform and the loading platform are respectively located at two ends of the feeding track; the method further comprises the following steps: if the sample to be detected on the first sample rack is finished in the second detection item type executed by the second detector, the feeding track drives the first sample rack to move towards the inlet position of the unloading platform, and the sample feeding mechanism is controlled to move the first sample rack loaded with the sample to be detected out of the inlet position of the unloading platform from the feeding track.
In one example, when the control device determines that the sample to be detected on the first sample rack is completed in the second detection item category executed by the second detector, the feeding track drives the first sample rack to move towards the inlet position of the unloading platform, and the sample feeding mechanism is controlled to move the first sample rack loaded with the sample to be detected out of the inlet position of the unloading platform from the feeding track. And simultaneously, controlling the sample introduction mechanism to load a second sample rack loaded with a sample to be detected from the loading platform to the feeding track by the control equipment, returning to the direction of driving the first sample rack to the sample analyzer through the feeding track, obtaining a sample identifier obtained by scanning the sample to be detected running by the scanning device, and determining the detection item category of the sample to be detected on the first sample rack according to the sample identifier.
In the sample testing control method according to the embodiment of the application, when it is determined that the sample to be tested on the first sample rack is completely tested on the first testing device in the testing item category and it is determined that the sample to be tested on the first sample rack does not include the second testing item category of the second testing device, the first sample rack is unloaded, and the second sample rack is loaded onto the feeding track. Therefore, the sample feeding mechanism can carry out sample feeding detection on a plurality of detectors by taking the sample rack as a unit, the requirement of carrying the sample rack to move back and forth among the detectors is reduced, and the loss of a feeding track can be reduced; in addition, the sample feeding mechanism can load two rows of sample racks in the same time period so that the first detector and the second detector work simultaneously, and therefore the utilization efficiency of the first detector and the second detector is improved, and the detection efficiency of the sample racks is further improved.
In some embodiments, before the moving the first sample rack by the feed track in the direction of the entrance position of the unloading platform, the method further comprises: judging whether at least one of the samples to be detected on the first sample rack meets a re-inspection condition according to the detection result of the second detector on the samples to be detected on the first sample rack; and if at least one sample to be detected meets the re-inspection condition, controlling the feeding track to convey the corresponding sample to be detected to the second sampling position so that the second detector can perform re-inspection on the sample to be detected.
Here, the determining whether at least one of the samples to be detected on the first sample rack satisfies the retest condition according to the detection result of the second detector on the samples to be detected on the first sample rack may be: and the control equipment acquires detection results corresponding to the samples to be detected on the first sample rack from the second detector and judges whether each detection result exceeds a preset value. If at least one of the samples to be detected meets the retest condition, controlling the feeding track to convey the corresponding sample to be detected to a second sampling position, so that the second detector performs the retest on the sample to be detected may refer to: and if the detection result corresponding to at least one sample to be detected exceeds a preset value, controlling the feeding track to convey the corresponding sample to be detected to a second sampling position so that the second detector can perform retesting on the sample to be detected.
In the sample detection control method according to the embodiment of the application, before the first sample rack is driven by the feeding track to move towards the inlet position of the unloading platform, whether the first sample rack needs to be retested or not is determined by judging whether at least one of the to-be-detected samples on the first sample rack meets a retest condition or not when detection is performed on the second detector, so that the possibility of repeatedly loading and removing the same sample rack is avoided, and the detection efficiency of the to-be-detected samples on the sample rack is improved.
In some embodiments, the sample injection mechanism further comprises an unloading platform, and the unloading platform and the loading platform are respectively located at two ends of the feeding track; after the step of judging whether the to-be-detected sample on the first sample rack contains the second detection item category of the second detector or not; the method further comprises the following steps: if the to-be-detected sample on the first sample rack does not contain the second detection item type of the second detector, the feeding track drives the first sample rack to move towards the inlet position of the unloading platform, and the sample feeding mechanism is controlled to move the first sample rack loaded with the to-be-detected sample out of the inlet position of the unloading platform from the feeding track.
In one example, when the control device determines that the sample to be detected on the first sample rack is executed on the first detector for detecting the item type and determines that the sample to be detected does not contain the second detecting item type of the second detector, the feeding track drives the first sample rack to move towards the inlet position of the unloading platform, and the sample feeding mechanism is controlled to move the first sample rack loaded with the sample to be detected out of the inlet position of the unloading platform from the feeding track. And simultaneously, controlling the sample introduction mechanism to load a second sample rack loaded with a sample to be detected from the loading platform to the feeding track by the control equipment, returning to the direction of driving the first sample rack to the sample analyzer through the feeding track, obtaining a sample identifier obtained by scanning the sample to be detected running by the scanning device, and determining the detection item category of the sample to be detected on the first sample rack according to the sample identifier.
According to the embodiment of the application, when the control device determines that the sample to be detected on the first sample rack is executed on the first detector to complete the detection item category and determines that the sample to be detected on the first sample rack does not contain the second detection item category of the second detector, the control device enables the first sample rack to be unloaded and simultaneously loads the second sample rack into the feeding track. Therefore, the sample feeding mechanism can carry out sample feeding detection on the plurality of detectors by taking the sample rack as a unit, the requirement that the sample rack is carried to move back and forth among the plurality of detectors is reduced, and the loss and consumption of the feeding track can be reduced; in addition, the sample feeding mechanism can load two rows of sample racks in the same time period so that the first detector and the second detector work simultaneously, and therefore the utilization efficiency of the first detector and the second detector is improved, and the detection efficiency of the sample racks is further improved.
In some embodiments, the feeding mechanism further comprises a temporary sample rack storage location located on the side of the unloading platform away from the loading platform, and before the first sample rack is carried by the feeding track to the direction of the entrance position of the unloading platform, the method further comprises: judging whether a second detection item type executed by the second detector by a prior sample rack exists or not; and if the second detection item type is executed by the second detector in the prior sample rack, controlling the feeding track to drive the first sample rack to move to the sample rack temporary storage position.
In some examples, when the control device determines that the first testing machine has performed testing of the sample to be tested on the first sample rack and the second testing machine has not performed testing of the sample to be tested on the previous sample rack, the control device controls the transport of the previous sample rack to the sample rack buffer for buffering and controls the sample injection mechanism to move the first sample rack loaded with the sample to be tested from the entrance position of the unloading platform from the feeding track. After the first sample rack is moved out of the entrance position of the unloading platform, the control device controls the feeding track to convey the previous sample rack from the temporary sample rack storage area to a second sampling position, so that the second detector continues to extract the sample to be detected at the second sampling position to perform detection of the corresponding detection item type. Simultaneously, the control device controls the sample feeding mechanism to load a second sample rack loaded with a sample to be detected from the loading platform to the feeding track; and returning to the step of driving the first sample rack to move towards the sample analyzer through the feeding track, obtaining a sample identifier obtained by scanning the running sample to be detected by the scanning device, and determining the detection item category of the sample to be detected on the first sample rack according to the sample identifier.
According to the sample detection control method, when the first detector finishes detecting the sample to be detected on the first sample rack and the second detector does not finish detecting the sample to be detected on the previous sample rack, the previous sample rack is conveyed to the sample rack temporary storage area for temporary storage, so that smooth unloading of the first sample rack is guaranteed, and the detection efficiency of the sample to be detected on the sample rack is improved.
In addition, in some embodiments, the control device determines whether the sample to be detected on the first sample rack contains the first detection item category of the first detector according to the sample identifier; if the to-be-detected sample on the first sample rack does not include the first detection item category of the first detector, the control device determines whether the to-be-detected sample on the first sample rack includes the second detection item category of the second detector, and executes the step S206.
