Description

Sample transmission detection method

Technical Field

The invention relates to the technical field of medical instruments, in particular to a sample transmission detection method.

Background

At present, detection systems capable of realizing sample automatic sampling batch measurement are very popular. The autosampler measurement is usually used to match the sample results in a numbered increment or by sample bar codes.

And the automatic sample injection detection system for matching the sample results in a numbering increasing mode is adopted, and the accuracy of sample measurement result matching is completely dependent on the accuracy of sample transportation. If the sample rack is jammed in the transportation process, the detection system cannot find and prompt in time, so that the sample number and the sample measurement result are matched in disorder, and clinical risks are generated.

For the automatic sample injection detection system which matches the sample result through the sample bar code, a code scanner needs to be configured, and most of blood sample detection systems on the market at present do not overlap the position where the sample is scanned with the position where the sample is collected due to the structural limitation. Therefore, after the sample is scanned, the sample needs to be moved for a certain distance to reach a sample collecting position, if the sample is jammed in the moving process, the detection system can not find and prompt in time, and the problem that the sample bar code number is matched with the sample detection result in disorder can also occur.

In conclusion, the automatic sample feeding measurement is carried out in a serial number increasing mode or through a sample bar code to match a sample result, and once clamping stagnation occurs in the movement process of a sample frame, the problem of error matching between the sample result and the serial number is caused. For the current blood sample detection system with automatic sample feeding batch measurement, the clamping stagnation of the sample rack can not be detected with a certain probability, so that the problem of incorrect matching of the sample result and the number can occur, and clinical risks are generated.

An embodiment of the invention provides a sample transmission detection method. The method is applied to a sample analysis system A for detecting a process of transporting a sample rack 400 by the sample analysis system A. After the sample transmission detection method detects the transmission of the sample rack 400, whether clamping stagnation occurs in the process of transporting the sample rack 400 can be detected, so that the error detection result is prevented from being provided due to the fact that the detection result of the sample is misplaced with the reference number of the sample, the safety is improved, and the clinical risk is reduced.

As shown in fig. 1 and fig. 2, the sample analysis system a is used for analyzing and detecting a sample to be detected to obtain a corresponding detection result, thereby meeting the use requirement. It should be noted that the specific kind of the sample to be measured is not limited, and in some embodiments, the sample to be measured includes a solid sample or a liquid sample. It will be appreciated that the testing of a liquid sample may be performed by carrying the liquid sample in a container such as a test tube and placing it on the sample holder 400. Further liquid samples include, but are not limited to, blood samples. When a blood sample is detected using the sample analysis system a of the present invention, the blood sample is loaded in the sample container 500 and sequentially placed on the sample rack 400. The sample rack 400 is used to carry a sample container 500 with a sample to be tested. Moreover, a plurality of sample containers 500 may be placed on each sample rack 400. In the present invention, a plurality means two or more. The sample container 500 has, for example, ten placement bits for carrying ten sample containers 500.

The left-right directions shown in fig. 2 are denoted as X1 and X2 directions, the front-back directions are denoted as Y1 and Y2 directions, and the up-down directions are denoted as Z1 and Z2 directions. Illustratively, the sample analysis system a includes a sample transport apparatus 100, a sample suction apparatus 200, a mixing apparatus 300, and a detection apparatus. The sample transporting device 100 can transport the sample rack 400 along the X1 direction to realize automatic transportation of the sample to be tested, so as to improve the sample injection efficiency and further improve the working efficiency of the sample analysis system a. The sample-absorbing device 200 may collect a sample in the sample container 500 placed on the sample rack 400 and transfer the collected sample to the detection device. The detection device may measure the sample aspirated by the sample aspiration device 200 to obtain parameters of the sample, such as Red Blood Cells (RBC), white Blood Cells (WBC), hemoglobin (HGB), and the like.

The sample transport device 100 transports the sample rack 400 in the first direction in an intermittent manner. Referring to fig. 5 to 7, the sample transporter 100 illustratively includes a support assembly 110, a loading assembly 120, a lateral transport assembly 130, a detection assembly, and an unloading assembly 140.

That is, the lateral transport assembly 130 may transport the sample rack 400 in the first direction by a preset interval, and then, the lateral transport assembly 130 returns to the initial position in the second direction. It will be appreciated that the first direction refers to the X1 direction and the second direction refers to the X2 direction. That is, the lateral transport assembly 130 reciprocates in the X1 direction and the X2 direction to continuously transport the sample rack 400 in the X1 direction.

Referring to fig. 3, 4 and 6, the sample holder 400 has a plurality of fixing holes 410 for fixing the sample container 500. The center distance between two adjacent fixing holes 410 is d. In this embodiment, the sample holder 400 moves along the X1 direction by a movement distance d, so that the sample container 500 in the next fixing hole 410 of the sample holder 400 is opposite to the sample position, which is called the sample holder 400 moves by one sample position. Moreover, the predetermined pitch is typically one sample position. The sample holder 400 further has an opening 420 and a groove 430 corresponding to the fixing hole 410, and the opening 420 is disposed along the Z direction, so as to expose the identification code 510 of the sample container 500, so as to facilitate scanning by the code reader 600 of the sample analysis system a. The groove 430 is located at the bottom of the sample rack 400 and can be matched with a fixing device of the sample rack 400, so as to press the sample rack 400 against the transverse transport assembly 130, that is, to fix the sample rack 400 in the Z1 and Z2 directions, so as to avoid the up-and-down movement of the sample rack 400.

It can be appreciated that each fixing hole 410 corresponds to one groove 430, and a step 440 is provided between two adjacent grooves 430. Thus, when the sample rack 400 does not move, the step 440 can limit the displacement of the sample rack 400 in the X1 and X2 directions, so as to ensure the accurate transportation of the sample rack 400. And, the bottom of the sample rack 400 has a plurality of support beams 450, the plurality of support beams 450 are spaced apart along the X1 direction, and any adjacent two support beams 450 are enclosed into a cavity 460 to form a plurality of cavities 460. Also, the positions of the plurality of cavities 460 are respectively in one-to-one correspondence with the plurality of fixing holes 410. When the sample rack 400 is transported, the transverse transport assembly 130 abuts against the support beam 450, and the sample rack 400 is transported along the X1 direction. After the transverse transport assembly 130 transports the sample rack 400 to a sample position, the transverse transport assembly 130 is separated from the support beam 450, and at this time, the transverse transport assembly 130 does not drive the sample rack 400 to move along the X2 direction for resetting.

The support assembly 110 includes an upper support plate 112 and a lower support plate 111 positioned below the upper support plate 112. The loading assembly 120, the lateral transport assembly 130, and the unloading assembly 140 are disposed between the upper support plate 112 and the lower support plate 111. Moreover, the sample rack 400 is carried at the upper support plate 112. It will be appreciated that the various moving members of the loading assembly 120, the lateral transport assembly 130, and the unloading assembly 140 may extend beyond the upper support plate 112 to move the sample rack 400.

Specifically, the upper support plate 112 has a loading waiting area 1121, an unloading waiting area 1123, a lateral transport waiting area 1122 between the loading waiting area 1121 and the unloading waiting area 1123, and an unloading area 1124 on one side of the unloading waiting area 1123. The loading waiting area 1121 is used to store the sample rack 400 to be inspected. The lateral transport waiting area 1122 is used to store the sample rack 400 to be laterally transported. The unload-waiting area 1123 is used to store the sample rack 400 after the lateral transportation is completed. The sample racks 400 in the unload standby area 1123 are eventually stored in the unload area 1124. Further, an avoidance gap 1126 and a clearance gap 1125 are provided between the lateral transport waiting area 1122 and the unloading waiting area 1123.

The loading assembly 120 includes a loading power source, a loading drive, and a loading pawl 121. The loading power source is connected with a loading transmission assembly, the loading transmission assembly is connected with a loading pushing claw 121, and the loading pushing claw 121 can expose the upper supporting plate 112. When the loading power source outputs power, the loading driving part can be driven to drive the loading pushing claw 121 to move. And, the loading driving member may drive the loading claw 121 to move along the Y2 direction, at this time, the loading claw 121 pushes the sample rack 400 from the loading waiting area 1121 to the lateral transportation waiting area 1122. After the pushing is completed, the loading driving member may drive the loading pawl 121 to move along the Y1 direction, return to the initial position, and wait for the pushing of the next sample rack 400. Alternatively, the loading power source includes, but is not limited to, an electric motor. The loading drive includes, but is not limited to, a ball screw drive.

The lateral transport assembly 130 may intermittently transport the sample racks 400 in the lateral transport standby area 1122 in a first, X1 direction and eventually transport the sample racks 400 to the unload standby area 1123. It should be noted that, after the transverse transport assembly 130 conveys the sample rack 400 by one sample position along the X1 direction, the transverse transport assembly 130 returns to the initial position in the X2 direction without load. That is, the shuttle of the transverse transport assembly 130 may enable transport of the sample rack 400 to ensure proper operation of the sample analysis system a.

Referring to fig. 7, exemplary lateral transport assembly 130 includes a lateral floor 131, a lateral power source 132, a lateral slider 133, and a sample abutment 134. The detection assembly includes a first position sensor 135, a first sensing element 136, a second position sensor 137, and a second sensing element 138. Since the detection assembly is used in conjunction with the lateral transport assembly 130, detection of movement of the sample rack 400 in the first direction, i.e., the X1 direction, is achieved. Accordingly, the construction and operation of the detection assembly and the lateral transport assembly 130 will be described. The method comprises the following steps:

The transverse power source 132 is disposed on the transverse bottom plate 131 and is in driving connection with the transverse sliding member 133. Optionally, the lateral power source 132 includes, but is not limited to, a stepper motor or a pneumatic cylinder, or the like. The transverse sliding member 133 is slidably disposed on the transverse bottom plate 131, and the transverse power source 132 can drive the transverse sliding member 133 to move along the X1 direction or the X2 direction relative to the transverse bottom plate 131. The sample abutment 134 is rotatably provided to the lateral slider 133 and moves in the X1 direction or the X2 direction with the lateral slider 133.

The first sensing member 136 is located at the lateral slider 133. The first sensing element 136 may be used in conjunction with the first position sensor 135. When the first sensing member 136 moves to the first position sensor 135, the first sensing member 136 may trigger the first position sensor 135. When the first sensing member 136 is far from the first position sensor 135, the first sensing member 136 does not trigger the first position sensor 135. It is understood that the lateral sliding member 133 may drive the first sensing member 136 to correspond to the first position sensor 135, or drive the first sensing member 136 away from the first position sensor 135. It can be understood that in the present embodiment, the first sensing element 136 corresponds to the first position sensor 135, which means that the first sensing element 136 overlaps the first position sensor 135 in the direction shown in fig. 11.

Referring to fig. 7 and 8, the lateral slider 133 further has a stopper 1331 thereon for restricting rotational displacement of the sample abutment 134. Illustratively, the stopper 1331 may be a stopper protrusion. The sample abutment 134 has a spindle mounting hole 1341, an idle surface 1342, a load surface 1343, and an abutment surface 1344. The load surface 1343 and the abutment surface 1344 face in the X1 direction, and the idle surface 1342 faces away from the X1 direction. The load surface 1343 is for being mated with the support beam 450 at the bottom of the sample rack 400, and the abutment surface 1344 is for being abutted with the stopper 1331 of the lateral slider 133. The sample abutment 134 is rotatably mounted to the lateral slider 133 through a rotation shaft mounting hole 1341. Also, the center of the rotation shaft mounting hole 1341 of the sample abutment 134 is not provided at the center of gravity of the sample abutment 134, but is provided offset from the center of gravity. Thus, when the sample abutting piece 134 is not acted by other external force, the sample abutting piece 134 naturally swings to a certain extent when rotating around the rotating shaft mounting hole 1341 as the rotating shaft.

The process of transporting the sample rack 400 by the lateral transport assembly 130 is as follows:

The initial position of the sample abutment 134 is shown in fig. 10. When the sample abutment 134 is located at the initial position, the sample abutment 134 is pressed under the upper support plate 112. That is, the empty surface 1342 of the sample abutment 134 is in contact with the lower surface of the upper support plate 112, the empty surface 1342 of the sample abutment 134 is resisted by the upper support plate 112, and the sample abutment 134 cannot swing. At this time, as shown in fig. 11, the relative positions of the first position sensor 135 and the first sensing element 136 on the lateral sliding element 133 are shown, the first sensing element 136 is located in the sensing area of the first position sensor 135, and the lateral sliding element 133 is at the initial position.

The transverse slider 133 can drive the sample abutment 134 to move along the X1 direction under the driving of the transverse power source 132. When the transverse sliding member 133 drives the sample abutting member 134 to move a distance along the X1 direction, the sample abutting member 134 corresponds to the avoidance gap 1125 of the upper support plate 112, and the sample abutting member 134 is no longer resisted by the upper support plate 112, and rotates along the R1 direction due to the eccentric arrangement, as shown in fig. 11, so that at least a portion of the sample abutting member 134 passes through the avoidance gap 1125 and extends into the bottom of the sample rack 400 on the upper support plate 112, as shown in fig. 12. The sample abutment 134 continues to rotate along the direction R1, and the abutment surface 1344 of the sample abutment 134 eventually abuts against the limiting part 1331 of the lateral sliding member 133 to stop rotating, at this time, the head of the sample abutment 134 is partially exposed from the upper support plate 112 and extends into the cavity 460 at the bottom of the sample holder 400.

As the lateral power source 132 continues to drive the lateral slide 133 to move the sample abutment 134 in the X1 direction, the load surface 1343 of the sample abutment 134 will contact the bottom support beam 450 of the sample rack 400, as shown in fig. 13, and transport the sample rack 400 in the X1 direction against the bottom support beam 450 of the sample rack 400. When the sample rack 400 moves along X1 to a sample position, the lateral power source 132 stops driving. The relative positions of the first position sensor 135 and the first sensing element 136 on the lateral sliding element 133 are shown in fig. 14, and the first sensing element 136 has moved away from the sensing area of the first position sensor 135.

Thereafter, the transverse power source 132 drives the transverse slider 133 reversely to move the sample abutment 134 in the X2 direction back to the initial position, and the empty surface 1342 of the sample abutment 134 returns to the state of being held against by the upper support plate 112. During the process that the transverse power source 132 drives the transverse sliding piece 133 to drive the sample abutting piece 134 to return to the initial position along the X2 direction, the sample rack 400 is acted by the sample blocking device and does not move along the X2 direction along the sample rack 400.

Optionally, a sample blocking device is used to block movement of the sample rack 400 in the X2 direction. Illustratively, the sample blocking means is a hold-down device for holding down the sample rack 400 to the upper support plate 112. Because the compressing device belongs to the prior art, the compressing device is not described in detail herein.

Optionally, the thickness of the sample abutment 134 is smaller than the width of the clearance gap 1125 formed in the upper support plate 112. Thus, the sample abutting piece 134 can extend out through the avoidance notch 1125 of the upper support plate 112, so that the sample abutting piece 134 is prevented from being blocked, and the accurate and reliable transportation of the sample rack 400 is ensured.

Alternatively, the number of the sample abutments 134 is at least two, and the at least two sample abutments 134 are arranged at intervals in the X1 direction. In this way, in the process of conveying the sample rack 400 from the transverse conveying waiting area 1122 to the unloading waiting area 1123, at least one sample abutting piece 134 can be ensured to abut against the supporting beam 450 at the bottom of the sample rack 400, so that the conveying of the sample rack 400 is realized, the dead zone is avoided in the conveying of the sample rack 400, and the conveying reliability of the sample rack 400 is ensured. Accordingly, the number of the clearance notches 1125 is equal to the number of the sample abutments 134. In the present embodiment, the number of the sample abutments 134 is two, and is arranged at intervals in the X1 direction. Moreover, the distance between the two sample abutting pieces 134 is a multiple of the sample position, so that the two sample abutting pieces 134 can simultaneously extend into the cavity 460 at the bottom of the sample rack 400, and the consistency of actions is ensured. Also, the distance between the two sample abutments 134 is smaller than the length of the sample rack 400, so that a dead zone can be avoided in the transfer of the sample rack 400. Correspondingly, the number of the clearance notches 1125 is two, and the clearance notches are arranged at intervals along the X1 direction.

Referring to fig. 7 and 17, the second sensing member 138 is rotatably mounted to the lateral base plate 131. The second sensing member 138 is used in conjunction with the second position sensor 137. When the second sensing member 138 rotates to the second position sensor 137, the second sensing member 138 may trigger the second position sensor 137, and the second position sensor 137 outputs the first signal. When the second sensing member 138 is far from the second position sensor 137, the second sensing member 138 does not trigger the second position sensor 137, and the second position sensor 137 outputs a second signal. That is, the second sensing member 138 is only rotated and not moved, and the second sensing member 138 and the second position sensing can detect the movement of the sample rack 400. It will be appreciated that the second sensing element 138 may correspond to the second position sensor 137 when the sample holder 400 is stationary, and that the second sensing element 138 may be moved away from the second position sensor 137 during movement of the sample holder 400. It will be appreciated that in this embodiment, the second sensing element 138 corresponds to the second position sensor 137, which means that the second sensing element 138 overlaps the second position sensor 137 in the direction shown in fig. 17.

The second sensing element 138 is structured as shown in fig. 9, and the second sensing element 138 includes a rotation mounting hole 1381, a support portion 1382, and a sensing portion 1383. The second sensing piece 138 is rotatably mounted to the lateral sliding piece 133 through a rotation mounting hole 1381. The center of the rotation mounting hole 1381 of the second sensing piece 138 is not disposed at the center of gravity of the second sensing piece 138, but is disposed offset from the center of gravity. Thus, when the second sensing element 138 is not acted by other external forces, the second sensing element 138 naturally swings around the rotation mounting hole 1381 as the rotation axis.

When the sample abutment 134 is in the initial position, the position of the second sensing member 138 relative to the sample rack 400 is shown in FIG. 17. At this time, the top 1382 of the second sensing element 138 is partially exposed through the avoidance notch 1126 of the upper support plate 112 and extends into the cavity 460 at the bottom of the sample rack 400, but the second sensing element 138 is not in contact with the support beam 450 at the bottom of the sample rack 400. And, the sensing portion 1383 of the second sensing piece 138 is located within the sensing region of the second position sensor 137. At this time, the second sensing member 138 triggers the second position sensor 137 and outputs the first signal. Assume that the first signal output by the second position sensor 137 is: and an output level V1.

Driven by the lateral power source 132, the sample abutment 134 carries the sample rack 400 in the X1 direction against the sample rack 400 bottom support beam 450, such that the sample rack 400 bottom support beam 450 gradually approaches and abuts the abutment 1382 of the second sensing member 138 in the X1 direction. At this time, the second sensing element 138 rotates along the R3 direction under the pressing force of the sample holder 400, as shown in fig. 18, the sensing portion 1383 of the second sensing element 138 gradually leaves the sensing area of the second position sensor 137. At this time, the second position sensor 137 outputs a second signal. Assume that the second signal output by the second position sensor 137 is: and an output level V2.

As the sample rack 400 continues to move in the X1 direction, the bottom support beam 450 of the sample rack 400 will gradually move away from the abutment 1382 of the second sensing member 138, and the second sensing member 138 will rotate in the R4 direction under its own weight, as shown in fig. 19, until it hits a stop (not shown). At this time, the abutment portion 1382 of the second sensing piece 138 re-exposes the upper support plate 112 and protrudes into the next cavity 460 at the bottom of the sample rack 400, and does not contact the bottom support beam 450 of the sample rack 400. And, the sensing portion 1383 of the second sensing piece 138 is returned to the sensing region of the second position sensor 137.

As can be seen, each time the sample abutment 134 pushes the sample rack 400 one sample position in the X1 direction, the sensing portion 1383 of the second sensing member 138 will generate 1: sensing area at second position sensor 137-off sensing area at second position sensor 137-state change at sensing area at second position sensor 137, corresponding to output signal of second position sensor 137 generated 1 time: v1- & gtV 2- & gtV 1, as shown in FIG. 20. And, the transition of the output level of the second position sensor 137 from v1→v2 and the transition from v2→v1 are each generated only 1 time, where V1> V2 or V1 < V2 may be used.

Optionally, the width of the abutment portion 1382 is smaller than the width of the relief notch 1126 formed in the upper support plate 112. Thus, the abutment portion 1382 of the second sensing element 138 can extend out through the avoiding notch 1126 of the upper supporting plate 112, so as to avoid the second sensing element 138 from being blocked, and ensure accurate transportation and detection of the sample rack 400.

Alternatively, the number of the second sensing elements 138 is at least two, and the at least two second sensing elements 138 are spaced apart along the X1 direction. In this way, in the process of conveying the sample rack 400 from the transverse conveying waiting area 1122 to the unloading waiting area 1123, at least one second sensing piece 138 can be guaranteed to be abutted against the supporting beam 450 at the bottom of the sample rack 400, so that detection of the conveying process of the sample rack 400 is realized, a dead zone is avoided in the conveying process of the sample rack 400, and the conveying reliability of the sample rack 400 is guaranteed. Accordingly, the number of relief notches 1126 is equal to the number of sample abutments 134 and the number of second position sensors 137 is equal to the number of second sensing elements 138. In this embodiment, the number of the second sensing members 138 is two, and the second sensing members are arranged at intervals along the X1 direction. And, the interval between the two second sensing pieces 138 is a multiple of the sample position, so that the two second sensing pieces 138 can simultaneously extend into the cavity 460 at the bottom of the sample rack 400, and the consistency of actions is ensured.

Moreover, the distance between the two second sensing members 138 is smaller than the length of the sample rack 400, so that the dead zone of the transmission detection of the sample rack 400 can be avoided. Correspondingly, the number of the avoidance notches 1126 is two, and the avoidance notches are arranged at intervals along the X1 direction, and the number of the second position sensors 137 is also two. It will be appreciated that, during the process of pushing the sample holder 400 in the X1 direction by one position by the sample abutment 134, the two second position sensors 137 may not be able to generate the pulse signal, but at least one sensor of the two second position sensors 137 may generate the pulse signal. By monitoring the number of pulse signals and the pulse width, it can be determined whether the sample rack 400 is normally carrying one sample site.

The unloading assembly 140 includes an unloading power source, an unloading transmission, and an unloading pusher dog. The unloading power source is connected with an unloading transmission assembly, the unloading transmission assembly is connected with an unloading pushing claw, and the pushing claw can be exposed out of the upper supporting plate 112. When the unloading power source outputs power, the unloading driving part can be driven to drive the unloading pushing claw to move. And, the unloading driving member can drive the unloading pushing claw to move along the Y1 direction, and at this time, the pushing claw pushes the sample rack 400 from the unloading waiting area 1123 to the unloading area 1124. After the pushing is completed, the unloading driving part can drive the unloading pushing claw to move along the Y2 direction, and return to the initial position to wait for the pushing of the next sample rack 400. Alternatively, the unloading power source includes, but is not limited to, an electric motor. The unloading transmission includes, but is not limited to, a ball screw transmission.

The sample suction device 200 includes a sampling needle and a sampling power source. The sampling power source may drive the sampling needle in the Y1, Y2 directions and the Z1, Z2 directions such that the sampling needle is inserted into the sample container 500 to aspirate the sample. It can be appreciated that the sampling needle and the sampling power source are in the prior art, and are not described in detail herein.

The mixing device 300 may shake the specimen in the specimen container 500 placed on the specimen rack 400 so that the specimen, which has been left standing for a while and has been subjected to component stratification, reaches a uniform state before being sampled. It will be appreciated that the mixing device 300 performs the mixing operation after the sample container 500 is removed from the sample holder 400, and the sample container 500 is returned to the sample holder 400 after the mixing operation is completed. It is understood that the mixing device 300 is a prior art, and is not described in detail herein.

Referring to fig. 5 and 6, the sample transportation device 100 has sampling bits, mixing bits, and code scanning bits, which are located between the lateral transportation waiting area 1122 and the unloading area 1124 of the upper support plate 112 in the X1 direction. And the sampling bit, the mixing bit and the code scanning bit are arranged. That is, the sample container 500 with the code bits scanned moves one sample bit and then reaches the mix bit, and the sample container 500 with the mix bit moves one sample bit and then reaches the sample bit.

The transverse transport assembly 130 may drive the sample rack 400 to move along the X1 direction, so that the sample containers 500 in the sample rack 400 move to the code scanning position, the mixing position and the sampling position one by one. After the sample rack 400 moves to the code scanning position, the code reader 600 may scan the identification code 510 of the sample container 500, and then the transverse transport assembly 130 conveys the sample container 500 in the code scanning position to the mixing position, and the mixing device 300 mixes the sample containers 500. The lateral transport assembly 130 then transports the sample container 500 at the mix station to the sampling station where the sample is pipetted by the pipetting device 200.

Referring to the figures, an embodiment of the present invention provides a sample transmission detection method applied to a sample analysis system a, where the sample analysis system a includes a transverse transport assembly 130, a controller, and a processor, and the method includes the following steps:

the controller controls the lateral transport assembly 130 to move the sample rack 400 a preset distance in the first direction;

The controller controls the transverse transport assembly 130 to return to the initial position in the second direction;

the processor receives the actual information and compares the actual information with preset information to judge whether the movement of the sample rack 400 in the first direction has clamping stagnation;

if the sample rack 400 has a clamping stagnation, detecting the abnormal flow and triggering a prompt.

The processor may receive the actual information during the process of controlling the transverse transport assembly 130 to move the sample rack 400 by one sample position along the first direction and during the process of controlling the transverse transport assembly 130 to reset along the second direction by the controller. It is understood that the actual information herein includes, but is not limited to, displacement information, time information, pulse information, sign information, etc., but may be other information that can be compared for matching. The processor stores therein preset information when the sample holder 400 moves, which matches with the actual information, that is, when the actual information is displacement information, the preset information is also displacement information.

In this way, the processor can compare the actual information with the preset information, so as to determine whether there is a clamping stagnation in the process of moving the sample holder 400 by one sample position along the first direction. When the actual information is consistent with the preset information, the sample rack 400 has no clamping stagnation, which indicates that the detection flow of the sample is normal. At this time, the sample transporting device 100 has no abnormality in the operation process, the sample containers 500 may be sequentially transported to the sampling position, and the sample sucking device 200 may continuously suck the samples in the sample containers 500 on the sample rack 400, so as to realize normal detection of the samples. When the actual information is inconsistent with the preset information, the sample rack 400 has a clamping stagnation, which indicates that the detection flow of the sample is abnormal. At this time, the sample analysis system a triggers a prompt, prompting the operator that the sample rack 400 has a stuck problem.

The sample analysis system a trigger prompt here refers to: triggering a popup or triggering an acousto-optic device. It will be appreciated that the sample analysis system a has a display screen, and that when the sample analysis system a triggers a prompt, a pop-up window may be popped up on the display screen to prompt the operator that there is a jam in the sample rack 400. It will be further appreciated that the audible and visual device may emit an audible alarm or a light alarm, or a combination of audible and light alarm, to indicate to the operator that there is a jam in the sample holder 400. Of course, in other embodiments of the present invention, the sample analysis system a trigger prompt may be another component capable of sending a prompt signal to an operator.

It is noted that a processor is used to provide computing power, illustratively a CPU. The controller has control capability.

By comparing the actual information with the preset information, it is determined whether the movement of the sample rack 400 along the first direction has a clamping stagnation. Therefore, the problem of clamping stagnation in the moving process of the sample rack 400 along the X1 direction can be monitored, the problem of clamping stagnation of the sample rack 400 is avoided, the sample sucking device 200 is further guaranteed not to repeatedly suck samples of the samples in the same sample container 500, the problem that the sample result and the label are erroneously matched due to the clamping stagnation of the sample rack 400 at present is effectively solved, and therefore dislocation of the sample result is avoided, safety is improved, and clinical risks are reduced.

In one embodiment, the sample analysis system a further includes a detection assembly, the lateral transport assembly 130 includes a lateral bottom plate 131 for supporting the sample rack 400 and a lateral sliding member 133 capable of moving along a first direction relative to the lateral bottom plate 131, and the detection assembly detects an actual displacement generated by the lateral sliding member 133 when the lateral sliding member 133 moves the sample rack 400; the actual information includes actual displacement information of the lateral slider 133;

The preset information includes a preset movement distance when the lateral slider 133 conveys the sample rack 400 in the first direction, and/or a preset movement distance when the controller controls the lateral slider 133 to return to the initial position in the second direction;

Detecting actual displacement information of the transverse slider 133 and transmitting the actual displacement information to a processor, and comparing the actual displacement information with preset information by the processor;

if the actual displacement information is not consistent with the preset information, detecting the abnormal flow and triggering prompt.

When the transverse slider 133 conveys the sample rack 400 along the X1 direction through the sample abutment 134, the detection assembly can detect the movement distance of the transverse slider 133 during movement and determine whether the movement of the sample rack 400 is jammed according to the actual displacement. It can be appreciated that, in the process that the transverse slider 133 moves the sample rack 400 by one sample position through the sample abutment 134, the movement distance of the transverse slider 133 is constant, and correspondingly, in the process that the transverse slider 133 drives the sample abutment 134 to return to the initial position, the movement distance of the transverse slider 133 is also constant. It will be appreciated that the distance that the traverse slider 133 returns to the initial position in the X2 direction after moving in the X1 direction is also constant. The clamping stagnation of the sample rack 400 can cause the movement distance of the transverse sliding member 133 to be reduced, on the basis, the fixed movement distance of the transverse sliding member 133 is the preset information of the transverse sliding member 133, the actual displacement information of the transverse sliding member 133 is detected through the detection assembly, and the actual displacement information is transmitted to the processor. The processor compares the actual displacement information of the lateral slider 133 with preset information, and determines whether the actual displacement information matches the preset information. If the actual displacement information matches the preset information, the sample rack 400 has no clamping stagnation, and the detection flow is normal. If the actual displacement information does not match the preset information, the sample rack 400 has clamping stagnation, the detection flow is abnormal, and the sample analysis system A triggers prompt.

It will be appreciated that the actual displacement information of the traverse slider 133 may be converted into information of the actual movement distance, movement time, number of steps of the stepping motor, etc. of the traverse slider 133. The method comprises the following steps:

Referring to fig. 21 to 24, in the first embodiment, the sample analysis system a further includes a statistic member, the detection assembly includes a first sensing member 136 and a first position sensor 135, the first sensing member 136 is disposed on the lateral sliding member 133, the first position sensor 135 is disposed on the lateral bottom plate 131, the first sensing member 136 overlaps the first position sensor 135, the first position sensor 135 is triggered, and the actual displacement information refers to the actual displacement of the first sensing member 136 on the lateral sliding member 133;

The method further comprises the following steps:

after the controller controls the lateral slider 133 to return to the initial position in the second direction, determining whether the first sensing member 136 triggers the first position sensor 135;

the first sensing element 136 is determined to trigger the first position sensor 135 and the statistics record the actual displacement information and transmit it to the processor.

The controller controls the first sensing member 136 to move relative to the first position sensor 135 during the movement of the lateral slider 133 in the X1 direction and the X2 direction. Thus, when the first sensing member 136 is far from the first position sensor 135, the first position sensor 135 cannot detect the first sensing member 136, i.e., the first sensing member 136 does not trigger the first position sensor 135. When the first sensing member 136 moves to a position corresponding to the first position sensor 135, the first sensing member 136 triggers the first position sensor 135. The first position sensor 135 is triggered by the first sensing element 136 to determine the actual displacement of the lateral slider 133 to move the first sensing element 136.

Referring to fig. 7, 15 and 16, the principle of detecting actual displacement information of the lateral slider 133 in cooperation with the first position sensor 135 by the first sensing member 136 is as follows:

The transverse slide 133 normally carries the sample piece: as shown in fig. 15, when the sample abutment 134 is located at the initial position, it is assumed that the first sensing piece 136 on the lateral slider 133 is located at the point P0. After the sample abutment 134 on the lateral slide 133 conveys the sample rack 400 one sample position in the X1 direction, the first sensing member 136 follows the lateral slide 133 to point P1. When the lateral slider 133 returns to the initial position in the X2 direction, the first sensing member 136 and the sample abutment member 134 follow the lateral slider 133 to return to the initial position, and in this process, it is further assumed that the first sensing member 136 triggers the first position sensor 135 at the point Q. Wherein the distance between the P0 point and the P1 point is d1, and the distance between the P1 point and the Q point is d2.

As shown in fig. 16, it is assumed that jamming occurs in the process of transporting the sample rack 400 in the X1 direction by the lateral slider 133 through the sample abutment 134. At this time, the first sensing element 136 on the lateral sliding element 133 cannot reach the point P1 but only the point P2. While the transverse slider 133 drives the first sensing element 136 and the sample abutment 134 to return to the initial position, the first position sensor 135 is still triggered at the point Q. Wherein the distance between the P0 point and the P2 point is d3, and the distance between the P2 point and the Q point is d4.

Obviously: d3 < d1, d4 < d2. That is, when the sample rack 400 is jammed during moving in the X1 direction, the movement distance of the transverse sliding member 133 driving the first sensing member 136 may be reduced, or the movement distance along the X1 direction may be reduced, or the movement distance along the X2 direction may be reduced, or the movement distance along the X1 direction and the movement distance along the X2 direction may be reduced. At this time, whether the sample holder 400 has a jam can be determined by the moving distance of the first sensing piece 136. Since the first sensing element 136 is disposed on the lateral sliding element 133, the lateral sliding element 133 moves to drive the first sensing element 136 to move synchronously. The movement distance of the transverse sliding member 133 along the X1 direction or the X2 direction is identical to the movement distance of the first sensing member 136, so that the present embodiment can determine whether the sample rack 400 is jammed in the transport along the X1 direction according to the actual displacement information of the first sensing member 136.

Moreover, the statistical component may detect actual displacement information of the first sensing component 136. The statistics are electrically or communicatively coupled to the processor. After the processor resets the statistic, the actual displacement information of the first sensing member 136 may be recorded by the statistic. After the statistics part records the actual displacement information, the actual displacement information is transmitted to the processor, and the processor can compare the actual displacement information with the preset displacement information to judge whether the actual displacement information accords with the preset displacement information or not so as to judge whether the sample frame 400 is transported along the X1 direction or not. If the actual displacement information matches the preset information, the sample rack 400 has no clamping stagnation, and the detection flow is normal. If the actual displacement information does not match the preset information, the sample rack 400 has clamping stagnation, the detection flow is abnormal, and the sample analysis system A triggers prompt. It can be understood that the displacement value in the preset information can be a fixed value or a certain value range.

Further, the method further comprises: the processor resets the statistics before the controller controls the traverse slide 133 to move the sample rack 400 a preset distance in the first direction, or before the controller controls the traverse slide 133 to return to the initial position in the second direction.

The processor resets the statistics before the controller controls the traverse slide 133 to move the sample rack 400 a preset distance in the first direction, or before the controller controls the traverse slide 133 to return to the initial position in the second direction. That is, the statistical member may be reset before the lateral sliding member 133 moves in the X1 direction, or the statistical member may be reset before the lateral sliding member 133 moves in the X2 direction, so that the actual displacement information of the first sensing member 136 may be counted by the statistical member. Specifically, when the statistic member is reset before the lateral slider 133 moves along the X1 direction, the statistic member may record only the actual displacement information of the first sensing member 136 along the X1 direction, or may record the sum of the actual displacement information of the first sensing member 136 along the X1 direction and the X2 direction. When the statistic member is reset before the lateral slider 133 moves in the X2 direction, the statistic member records only the actual displacement information of the first sensor 136 in the X2 direction.

Still further, the method further comprises: determining that the first sensing member 136 does not trigger the first position sensor 135;

The processor determines whether the lateral slider 133 has finished moving or whether the operation time of the lateral slider 133 exceeds one operation cycle;

if yes, detecting abnormal flow triggering prompt;

if not, then the determination is continued as to whether the first sensing element 136 triggers the first position sensor 135.

When it is determined that the first sensing member 136 does not trigger the first position sensor 135, the processor further determines whether the operation of the lateral power source 132 of the lateral slider 133 is completed or whether the operation time exceeds one operation cycle. If the determination is yes, it is indicated that the reverse driving of the transverse slider 133 by the transverse power source 132 fails to return to the initial position along the X2 direction with the sample abutment 134, and at this time, the detection flow is abnormal, and the sample analysis system a is triggered to trigger the prompt. If not, the processor continues to determine whether the first sensing element 136 triggers the first position sensor 135. It will be appreciated that one cycle of operation herein refers to the time taken for the traverse slide 133 to return to the initial position in the X2 direction after transporting the sample rack 400 one sample position in the X1 direction.

Optionally, the step of the statistics recording actual displacement information includes:

When the statistical component is a displacement sensor, the displacement sensor records the actual motion displacement of the first sensing component 136, and the processor converts the preset information into preset motion displacement and compares the actual motion displacement with the preset motion displacement;

or when the statistics element is a timer, the timer records the actual movement time of the first sensing element 136, the processor converts the preset information into the preset movement time, and compares the actual movement time with the preset movement time;

or when the stepping motor is adopted to drive the transverse sliding part 133 to move, the statistics part is a step counter, the step counter records the actual movement steps of the stepping motor, and the processor converts the preset information into the preset movement steps and compares the actual movement steps with the preset movement steps.

It will be appreciated that the actual displacement information of the first sensing member 136 may be converted by the actual movement displacement of the first sensing member 136. Illustratively, the statistical component is a displacement sensor that may detect an actual motion displacement of the first sensing component 136 and transmit the actual motion displacement to the processor. Meanwhile, the processor also converts the preset information into preset displacement information, and compares the actual movement displacement of the first sensing member 136 with the preset movement displacement.

The actual displacement information of the first sensing member 136 can also be converted by the actual movement time of the first sensing member 136. Illustratively, the statistical component is a timer. Since the movement speed of the lateral slider 133 is constant, it is known that the shorter the time the lateral slider 133 moves, the smaller the actual movement distance of the first sensing member 136, according to the inverse ratio of the certain distance of the speed to the time. At this time, the actual movement time of the first sensing member 136 may be recorded by a timer and transmitted to the processor. At the same time, the processor also converts the preset information into a preset movement time and compares the actual movement time of the first sensing member 136 with the preset movement time.

The actual displacement information of the first sensing member 136 may also be converted by the actual number of steps of movement of the stepper motor. Illustratively, the statistics are step counters. Since the movement distance of each step of the stepping motor is a fixed value, the number of movement steps of the stepping motor is fixed within a preset distance range. The smaller the number of steps of movement of the stepper motor, the smaller the actual distance of movement of the first sensing member 136. At this time, the actual number of moving steps of the first sensing member 136 may be recorded by the step counter and transmitted to the processor. At the same time, the processor also converts the preset information into a preset number of steps and compares the actual number of steps of the first sensing member 136 with the preset number of steps.

It will be appreciated that it may be: the first sensing member 136 has a reduced movement time, a reduced movement distance, or a reduced number of movement steps in the X2 direction. It may also be: the transverse sliding member 133 drives the first sensing member 136 to move in the X1 direction for a reduced time, a reduced moving distance or a reduced number of moving steps. Of course, it is also possible to: the first sensing member 136 moves in the X1 direction and the X2 direction for a time and a decrease, a distance and a decrease, or a number of steps and a decrease.

It will be appreciated that in all three ways, it can be determined whether there is a jam in the movement of the sample holder 400 in the X1 direction. In this embodiment, whether the sample rack 400 has a clamping stagnation is determined only by the manner of reducing the movement time, the movement distance or the number of movement steps of the first sensing member 136 along the X2 direction, and the other two manners are substantially the same as the principle of the above manner, which is not described herein.

The movement time, movement distance or movement steps of the first sensing member 136 along the X2 direction is reduced, namely: the time when the first sensing member 136 returns to the initial position to reach the trigger point Q of the first position sensor 135 is advanced, or the first sensing member 136 moves a shorter distance along the X2 direction, so that the first position sensor 135 is triggered. At this time, the controller only needs to monitor the time t1 from the start of the movement of the stepper motor to the time when the first position sensor 135 is triggered, the number of steps m1 operated by the stepper motor, or the movement distance s1 of the first sensing member 136 in the process of returning the sample rack 400 to the initial position along the X2 direction after the sample abutment member 134 conveys the sample rack 400 along the X1 direction, and compare the parameters with the parameters when no jamming normally occurs, so as to determine whether the movement of the sample rack 400 in the X1 direction is jammed. Of course, the driving source of the lateral slider 133 may be not a stepping motor but a pneumatic element. In this case, the controller may monitor the time t1 from when the pneumatic element starts to move to when the first position sensor 135 is triggered or the movement distance s of the first sensing member 136 during the process of returning the sample rack 400 to the initial position along the X2 direction after the sample abutment member 134 conveys the sample rack 400 along the X1 direction, and compare the time with the parameter when the clamping stagnation does not occur normally, and may determine whether the clamping stagnation occurs in the movement of the sample rack 400 along the X1 direction.

In the present embodiment, only the time t1 elapsed for detecting the first position sensor 135 and the number of steps m1 operated by the stepper motor are taken as examples for illustration, and the principle of detecting the movement distance s1 of the first sensing member 136 is substantially the same as that of the above-mentioned manner, and is not repeated here. Specifically, the method comprises the following steps:

the controller controls the stepping motor to drive the transverse sliding piece 133 to drive the sample rack 400 to convey the sample rack 400 to a sample position along the first direction;

the controller controls the stepping motor to reversely drive the transverse slider 133 to return to the initial position along the second direction;

The processor determines that the first position sensor 135 is triggered by monitoring the output signal of the first position sensor 135 for a transition;

The first position sensor 135 is triggered and the processor records the value of the timer or the value of the step counter when the first position sensor 135 is triggered.

The controller controls the stepper motor to drive the traverse slide 133 with the sample abutment 134 to carry the sample rack 400 one sample position in the X1 direction, and the processor resets the timer or step counter before the stepper motor is ready for reverse movement. The controller controls the stepper motor to drive the traverse slide 133 back to the home position along the X2 direction with the sample abutment 134. The processor determines whether the first position sensor 135 is triggered by the first sensing element 136 by monitoring whether a transition occurs in the output signal of the first position sensor 135.

If the first position sensor 135 is triggered, the processor records the timer number t1 or the step counter number m1 when the first position sensor 135 is triggered. It is then determined whether the recorded timer value t1 or the value m1 of the step counter is smaller than the threshold value. The thresholds here are: the corresponding timer value or step counter in normal conditions, in which no jamming of the sample rack 400 occurs, prevents erroneous determination of the margin. If the timer value t1 or the value m1 of the step counter is not smaller than the threshold value, the detection flow is normally ended. If the timer value t1 or the value m1 of the step counter is smaller than the threshold value, triggering the sample analysis system A to trigger prompt, and ending the detection process abnormally.

If the first position sensor 135 is not triggered, the processor further determines if the stepper motor is running over or if the stepper motor is running for more than one run period. If yes, it is indicated that the step motor fails to reversely drive the transverse slider 133 to return to the initial position along the X2 direction with the sample abutment 134, and then the sample analysis system a is triggered to trigger a prompt. If not, the processor continues to determine whether the first position sensor 135 is triggered.

It will be appreciated that the actual displacement information of the traverse slide 133 may be converted into information such as the number of pulses. The method comprises the following steps:

Referring to fig. 22, in the second embodiment, the detecting assembly further includes a second sensing member 138 and a second position sensor 137, the second sensing member 138 is swingably disposed on the lateral base plate 131, and the second position sensor 137 is disposed on the lateral base plate 131; the second sensing element 138 overlaps the second position sensor 137, the second position sensor 137 being triggered; the method further comprises the following steps:

The transverse sliding member 133 drives the sample rack 400 to move along the first direction and can drive the second sensing member 138 to move, so that the second sensing member 138 generates actual movement displacement relative to the second position sensor 137;

converting the actual motion displacement into a pulse signal, and recording the actual pulse number;

the processor judges whether the actual pulse number is normal or not;

If the actual pulse number is equal to the preset pulse number, the detection process is finished, and the controller controls the transverse sliding piece 133 to return to the initial position along the second direction;

if the actual pulse number is smaller or larger than the preset pulse number, detecting the abnormality of the flow and triggering the prompt.

It will be appreciated that during transport of the sample rack 400 in the X1 direction by the lateral slide 133 to a sample position, the support beam 450 at the bottom of the sample rack 400 will contact the abutment 1382 of the second sensing member 138 and disengage the sensing portion 1383 of the second sensing member 138 from the second position sensor 137. After the sample rack 400 is transported to one sample position by the lateral slider 133, the support beam 450 at the bottom of the sample rack 400 is separated from the abutment portion 1382 of the second sensing member 138, and the sensing portion 1383 of the second sensing member 138 corresponds to the second position sensor 137.

It will be appreciated that the second sensing member 138 is moved away from the second position sensor 137 or the corresponding second position sensor 137, such that the second sensing member 138 generates an actual movement displacement relative to the second position sensor 137, and the second sensing member 138 triggers the second position sensor 137 to generate a signal. Specifically, the transverse sliding member 133 drives the sample rack 400 to move along the X1 direction, the transverse sliding member 133 has a movement displacement, and the sensing portion 1383 of the second sensing member 138: the sensing area of the second position sensor 137-out of the sensing area of the second position sensor 137-in the sensing area of the second position sensor 137, wherein the actual movement displacement of the second sensing element 138 relative to the second position sensor 137 increases and decreases first, and the output signal of the corresponding second position sensor 137 is generated 1 time: v1- & gtV 2- & gtV 1, as shown in FIG. 20. At this point, the actual motion displacement may be converted into a pulse signal, indicating a pulse signal.

In the process of transporting the sample rack 400 to the X1 direction by the lateral slider 133 by one sample position, the support beam 450 at the bottom of the sample rack 400 is abutted only to the abutment portion 1382 of the second sensing member 138, and accordingly, the second position sensor 137 outputs a pulse signal. At this time, the actual pulse number is recorded, and the actual pulse number is fed back to the processor, and the processor judges whether the actual pulse number meets the expectations or not. If the actual number of pulses is equal to the preset number of pulses, the detection process is finished, which indicates that the sample rack 400 is not stuck. If the actual pulse number is smaller or larger than the preset pulse number, detecting abnormal flow and triggering the sample analysis system A to trigger prompt.

Further, the step of converting the actual motion displacement into a pulse signal and recording the actual pulse number includes:

The processor controls the pulse counter to reset before the controller controls the movement of the traverse slide 133 to move in the first direction;

after the controller controls the movement of the traverse slider 133 in the first direction, the pulse counter records the number of actual pulses output by the second position sensor 137 and transmits the number to the processor.

It will be appreciated that the lateral slide 133 moves the sample holder 400 one sample position in the X1 direction and that the lateral slide 133 is unloaded in the X2 direction. That is, the sample rack 400 can move only in the X1 direction and cannot be transported in the X2 direction. Since the sample holder 400 can control the second sensing member 138 to generate a pulse signal with respect to the second displacement sensor only during movement, it is necessary to record the number of pulses during movement of the traverse slider 133 in the first direction. Specifically, before the transverse slider 133 moves in the X1 direction, the pulse counter is reset, so that the pulse counter is accurately counted. And after the movement of the traverse slider 133 in the X1 direction is completed, the actual pulse number of the pulse signal is recorded by the pulse counter and transmitted to the processor.

Referring to fig. 23, still further, the step of recording the number of actual pulses output by the second position sensor 137 by the pulse counter further includes:

Before the controller controls the movement of the lateral slider 133 in the first direction, the processor determines that the second position sensor 137 outputs the first signal;

after the controller controls the movement of the lateral slider 133 in the first direction, the processor determines that the second position sensor 137 outputs a second signal;

The processor determines that the second position sensor 137 outputs the first signal when the controller controls the movement of the lateral slider 133 in the first direction to stop;

the pulse counter records the actual number of pulses.

Before the lateral sliding member 133 moves along the X1 direction, the lateral sliding member 133 is at an initial position, the abutment portion 1382 of the second sensing member 138 is located in the cavity 460 at the bottom of the sample holder 400, and the sensing portion 1383 of the second sensing member 138 corresponds to the second position sensor 137, at this time, the second position sensor 137 outputs the first signal V1. Then, during the process of transporting the sample rack 400 along the X1 direction by the lateral slider 133 to transport one sample position, the support beam 450 at the bottom of the sample rack 400 abuts against the abutment portion 1382 of the second sensing member 138, so that the sensing portion 1383 of the second sensing member 138 is separated from the second position sensor 137, and at this time, the second position sensor 137 outputs the second signal V2. After the sample rack 400 is transported in the X1 direction by the lateral slider 133 a sample position, the lateral slider 133 stops moving in the X1 direction, the abutment portion 1382 of the second sensing member 138 is located in the cavity 460 at the bottom of the sample rack 400, and the sensing portion 1383 of the second sensing member 138 corresponds to the second position sensor 137, at which time the second position sensor 137 outputs the first signal V1. At this time, the pulse counter records the actual number of pulses output from the second position sensor 137. It will be appreciated that when the sample rack 400 is normally transported, the signal output by the second position sensor 137 is: v1, V2 and V1, and the number of actual pulses recorded by the pulse counter is one. The transition from the second position sensor 137 outputting the first signal V1 to the second signal V2 is referred to as the second position sensor 137 outputting the first transition signal, and the transition from the second position sensor 137 outputting the second signal V2 to the first signal V1 is referred to as the second position sensor 137 outputting the second transition signal, and is collectively referred to as the transition signal.

Further, if the processor does not determine that the second position sensor 137 outputs the jump signal, the processor will cycle to determine whether the second position sensor 137 outputs the jump signal.

The process of judging whether the clamping stagnation exists in the transportation of the sample rack 400 by adopting the second sensing piece 138 and the second position sensor 137 in a matching way is as follows: the pulse counter is controlled to reset before the transverse slider 133 moves the sample holder 400 in the X1 direction. Then, the lateral slider 133 conveys the sample rack 400 by one sample position in the X1 direction, and records the actual number of pulses output from the second position sensor 137. The processor determines whether the number of actual pulses meets expectations. If the actual pulse number is equal to the preset pulse number, the detection flow is ended. If the actual pulse number is smaller or larger than the preset pulse number, detecting abnormal flow and triggering the sample analysis system A to trigger prompt.

Optionally, the step of the pulse counter recording the number of actual pulses output by the second position sensor 137 further includes:

When the second position sensor 137 outputs the first signal, the processor controls the pulse width timer to reset;

When the second position sensor 137 outputs the second signal, a pulse width timer is started to perform pulse width timing;

When the second position sensor 137 outputs the first signal, the pulse width timer stops counting, and records the actual pulse width;

If the actual pulse width exceeds the range of the preset pulse width, detecting abnormal flow and triggering prompt;

if the actual pulse width is within the range of the preset pulse width, the pulse counter counts.

The pulse width t2 output by the second position sensor 137 is influenced by the width of the support beam 450 at the bottom of the sample holder 400, the shape of the abutment 1382 of the second sensing member 138, and the speed of movement of the stepper motor and the sample holder 400, but once the above parameters are determined, the pulse width t2 output by the second position sensor 137 is substantially stable, i.e., is a relatively constant value. When the lateral slider 133 is jammed in transporting the sample rack 400 along the X1 direction, the pulse width t2 output by the second position sensor 137 may be abnormal, and the pulse width t2 may be greater than the normal pulse width or may be less than the normal pulse width.

The detection process of the pulse width t2 output from the second position sensor 137 is: it is determined whether the second position sensor 137 outputs the first signal. If the second position sensor 137 outputs the first signal, the processor controls the pulse width timer to reset. If the second position sensor 137 does not output the first signal, it is continuously determined whether the second position sensor 137 outputs the first signal. After the pulse width timer is reset, it is determined whether the second position sensor 137 outputs a second signal. If the second position sensor 137 outputs the second signal, the pulse width timer is started to perform pulse width timing. If the second position sensor 137 does not output the second signal, it is continuously determined whether the second position sensor 137 outputs the second signal. When the pulse width timer is started, it is determined whether the second position sensor 137 outputs the first signal. If the second position sensor 137 outputs the first signal, the pulse width timer stops counting. If the second position sensor 137 does not output the first signal, it is continuously determined whether the second position sensor 137 outputs the first signal.

The processor judges the pulse width of the pulse counter, and if the pulse width is in the range of [ T1, T2], the pulse counter is considered to record effective pulses, and the pulse number is counted to be +1. If the pulse width is < T1 or > T2, then an invalid pulse is considered to be recorded, possibly caused by jamming of the traverse slide 133 in transporting the sample rack 400 in the X1 direction. If the pulse width is not within the range of [ T1, T2], detecting abnormal flow, and triggering a sample analysis system A to trigger prompt.

Optionally, the number of the second sensing elements 138 is at least two, the at least two second sensing elements 138 are arranged at intervals along the first direction, and the number of the position sensors is also at least two and corresponds to the positions of the at least two second sensing elements 138;

the actual number of pulses output by one of the second position sensors 137 is equal to the preset number of pulses, and the detection process ends.

When the sample rack 400 moves one sample position along the X1 direction, if the bottom support beam 450 of the sample rack 400 is only abutted against one of the second sensing elements 138, only the second position sensor 137 corresponding to the abutted second sensing element 138 triggers the jump signal, and the rest of the second position sensors 137 not abutted against the second sensing element 138 do not trigger the jump signal, the number of pulses output by the second position sensor 137 is not determined, but only the number of pulses output by the second position sensor 137 corresponding to the abutted second sensing element 138 is determined. If the bottom support beam 450 of the sample rack 400 is simultaneously abutted against at least two second position sensors 137 during the movement of the sample rack 400 by one sample position along the X1 direction, only the number of pulses output by one of the second position sensors 137 is required to meet the requirement. The judgment condition is that the number of pulses output from one of the second position sensors 137=1, that is, the number of pulses output from the second position sensor 137 is greater than or less than 1, is judged as abnormal.

Illustratively, when the number of the second sensing elements 138 is two, the second position sensors 137 on the left side are denoted as M1, and the second position sensors 137 on the right side are denoted as M2 in the X1 direction. If the bottom support beam 450 of the sample frame 400 does not abut against the first sensing member 136 at the position M1 during the movement of the sample frame 4002 by one sample position along the X1 direction, the number of pulses output by the second position sensor 137M1 is not determined, but only the number of pulses output by the second position sensor 137M2 is determined. Similarly, if the bottom support beam 450 of the sample rack 400 does not abut against the first sensing member 136 at the position M2 during the movement of the sample rack 400 by one sample position along the X1 direction, the number of pulses output by the second position sensor 137M2 is not determined, but only the number of pulses output by the second position sensor 137M1 is determined. If the bottom support beam 450 of the sample rack 400 is simultaneously abutted against the second position sensors 137M1 and M2 during the movement of the sample rack 400 by one sample position along the X1 direction, only the number of pulses output by one of the second position sensors 137M1 and M2 is required to meet the requirement.

In the third embodiment, the first embodiment can also be combined with the second embodiment. That is, the first sensing element 136 and the first position sensor 135 are used to determine whether the sample rack 400 has a clamping stagnation along the X1 direction, and the second sensing element 138 and the second position sensor 137 are used to determine whether the sample rack 400 has a clamping stagnation along the X1 direction. Since the detection principle has been described in detail in the above embodiments, details are not repeated here. It will be appreciated that the movement distance, movement time, number of movement steps, pulse width may be limited by structural assembly, etc., and thus, the first sensing member 136 and the second sensing member 138 together detect whether the sample rack 400 is jammed along the X1 direction.

And, only when the first sensing piece 136 and the second sensing piece 138 detect that the sample rack 400 has no clamping stagnation at the same time, the detection flow of the sample rack 400 is normal, and as long as one of the first sensing piece 136 and the second sensing piece 138 detects that the sample rack 400 has clamping stagnation, the detection flow is abnormal, and the sample analysis system a triggers a prompt.

Referring to fig. 24, in the fourth embodiment, the sample analysis system a includes the code reader 600, and at this time, the judgment of whether or not the sample rack 400 has a jam can be achieved by the scanning function of the code reader 600. The sample analysis system A has a scanning position, each sample container 500 has an identification element, the transverse transport assembly 130 drives the sample container 500 to move to the scanning position, and the code reader 600 scans the identification element at the scanning position;

the method further comprises the following steps:

the controller controls the code reader 600 to read the identification piece corresponding to the sample container 500X _n in the current scanning position and transmit the identification piece to the processor;

the processor compares the identification piece corresponding to the sample container 500X _n with the identification piece corresponding to the previous sample container 500X _n-1;

the identification piece corresponding to the sample container 500X _n is different from the identification piece corresponding to the previous sample container 500X _n-1, and the detection process is finished.

By reading the corresponding identification piece of the sample container 500, it is determined whether the sample rack 400 is jammed in the transport along the X1 direction. Specifically, the processor determines whether there is a sample rack 400 carrying sample containers 500 to be transported to the scanning site of sample analysis system a, otherwise the detection process is directly terminated. If yes, the controller controls the code reader 600 to read the identification piece corresponding to the sample container 500X _n in the current scanning bit, and records the identification piece through the processor. The processor then compares the identifier corresponding to the current sample container 500X _n with the identifier corresponding to the previous sample container 500X _n-1. If the identification piece corresponding to the sample container 500X _n is different from the identification piece corresponding to the previous sample container 500X _n-1, the detection process is ended.

Optionally, the identifier comprises an identification code 510 located on the sample container 500, a position code located on the sample holder 400, or a marking located on the sample holder 400. Of course, the identification member may be other identifiable marks, indicia, etc. It will be appreciated that the code reader 600 may scan the identification code 510 corresponding to the current sample container 500, may scan the position code corresponding to the sample holder 400 where the current sample container 500 is located, and may scan the symbol corresponding to the sample holder 400 where the current sample container 500 is located. By matching and matching the identification pieces corresponding to the sample containers 500 moving to the scanning position in sequence, when the two identification pieces are different, the sample rack 400 is indicated to have no clamping stagnation position, and the detection flow runs normally. When the two identification pieces are the same, the sample rack 400 is indicated to have clamping stagnation, the detection flow is abnormal, and the sample analysis system A triggers prompt.

In one embodiment, the identifier corresponding to sample container 500X _n is different from the identifier corresponding to previous sample container 500X _n-1, detecting a process anomaly and triggering a prompt.

Typically, the identifiers of the sample containers 500 on the same sample rack 400 are different. When the identification piece corresponding to the sample container 500X _n is identical to the identification piece corresponding to the previous sample container 500X _n-1, this means that: during the transport of the sample rack 500 along the X1 direction by the lateral slider 133, the sample container 500 in the scanning position is not transported by one sample position, and is still in the scanning position, indicating that there is a jam in the sample rack 500. At this time, the detection flow is abnormal, and the sample analysis system a triggers a prompt.

When at least two of the identifiers of the sample containers 500 on the same sample rack 400 are identical, a one-step determination is required when the identifier corresponding to the sample container 500X _n is identical to the identifier corresponding to the previous sample container 500X _n-1.

Specifically, the sample containers 500X _n are spaced apart from the previous sample containers 500X _n-1 on the sample rack 400, and the method further comprises the steps of:

The identification piece corresponding to the sample container 500X _n is identical to the identification piece corresponding to the previous sample container 500X _n-1;

The processor determines whether the sample container 500X _n is adjacent to a previous sample container 500X _n-1;

If not, ending the detection flow;

if the two paths are adjacent, detecting the abnormality of the flow and triggering the prompt.

There are also two cases when the identifier corresponding to sample container 500X _n is identical to the identifier corresponding to previous sample container 500X _n-1, and whether sample container 500X _n is adjacent to sample container 500X _n-1. It will be appreciated that there may be instances where sample containers 500 with the same label are on the same sample rack 400. At this time, when the operator is required to load the sample containers 500 onto the sample rack 400, it is ensured that the adjacent two sample containers 500 have different identifiers. That is, the sample containers 500X _n of the same identifier are spaced apart from the sample containers 500X _n-1.

In this way, when the identifier corresponding to the sample container 500X _n is identical to the identifier corresponding to the previous sample container 500X _n-1, it is first determined whether the sample container 500X _n is adjacent to the sample container 500X _n-1. If the adjacent identification pieces corresponding to the sample containers 500X _n are the same as and adjacent to the identification pieces corresponding to the previous sample containers 500X _n-1, at this time, it indicates that the sample rack 400 has a clamping stagnation, the detection flow is abnormal, and the sample analysis system a triggers a prompt. If not, that is, the identification piece corresponding to the sample container 500X _n is the same as and not adjacent to the identification piece corresponding to the previous sample container 500X _n-1, the detection process is finished, and the sample analysis system a operates normally.

In this embodiment, the code reader 600 scans the identification code 510 of the sample container 500, where the identification code 510 is the ID number of the sample, is the unique identifier of the sample, and can display the detection item information, the user information, and the like of the sample. By comparing the identification code 510 of the sample container 500, it is judged whether or not there is a jam in the movement of the sample holder 400 in the X1 direction. Specific:

The processor first determines whether there is a sample rack 400 carrying sample containers 500 to be transported to the scan site of sample analysis system a, otherwise the testing process is directly terminated. If yes, the controller controls the code reader 600 to read the identification code 510 of the sample container 500X _n in the current scanning bit, and records the identification code 510 through the processor. The processor then compares the identification code 510 of the current sample container 500X _n with the identification code 510 of the previous sample container 500X _n-1. If the identification code 510 of the sample container 500X _n is different from the identification code 510 of the previous sample container 500X _n-1, the detection process is ended. If the identification piece corresponding to the sample container 500X _n is the same as the identification piece corresponding to the previous sample container 500X _n-1, it is determined whether the sample container 500X _n is adjacent to the sample container 500X _n-1, if so, the detection flow is abnormal, the sample analysis system a triggers a prompt, and if not, the detection flow is ended.
