DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0026] The online sample suction track system provided in this embodiment is arranged on one side of the main track of the assembly line. In the assembly line, samples are usually transmitted in the form of single tubes. The sample tubes containing the samples stand upright on the test tube holders, and the test tube holders are transported to various modules along the assembly line. Usually, the modules are arranged in sequence along the main track of the assembly line. After passing through the input, centrifugation, and opening modules, the samples flow to the online sample suction module. The online sample suction module includes an online sample suction track system and a sample analyzer. The sample analyzer performs online sample suction on the target sample that flows to the sample suction position. After completing the sample suction action, the sample can return to the main track of the assembly line and continue to flow to other modules.

[0027] Reference Figure 1 As shown in the structural schematic diagram, an embodiment of the present application provides an online sample suction track system, including: a sample suction track 1, a return track 2, and a transfer track 3 arranged between the sample suction track 1 and the return track 2, the transfer track 3 includes at least two middle rotor tracks 31, each of the middle rotor tracks 31 corresponds to the length of a single sample analyzer, and the inlet and outlet sample ends of the middle rotor tracks 31 are respectively provided with a first track changing component 41 and a second track changing component 42, the first track changing component 41 is used to change the track of the sample located on the sample suction track 1 to the middle rotor track 31 or directly release it; the second track changing component 42 is used to change the track of the sample located on the middle rotor track 31 to the sample suction track 1 or directly release the sample located on the sample suction track 1.

[0028] In this embodiment, the sample suction track 1 is a track close to the sample analyzer, and the return track 2 is a track away from the sample analyzer. A transfer track 3 is set between the sample suction track 1 and the return track 2, and the transfer track 3 is used to transfer samples that do not need to be sucked by the current sample analyzer. In order to connect multiple sample analyzers in series, the transfer track 3 is divided into multiple sections of mid-rotor tracks 31, and the lengths of each mid-rotor track 31 can be equal or unequal. The length of the mid-rotor track 31 is determined according to the length of the sample analyzer. For example, in order to accommodate two sample analyzers of different lengths, the length of the first section of the mid-rotor track 31 is greater than the length of the second section of the track 31.

[0029] This embodiment takes two sample analyzers as examples to illustrate the sampling modes of the online sampling track system. When a sample flows from the main track of the assembly line to the sampling track, there are three possible sampling modes for the sample according to different sampling requirements, as shown in Table 1. In Table 1, "1" indicates that sampling is required, and "0" indicates that sampling is not required.

[0030] Table 1 Three sampling modes of samples under two sample analyzers

[0031] Aspiration mode Sample Analyzer A Sample Analyzer B The first 1 1 The second 1 0 The third 0 1

[0032] In the first sampling mode, the sample flows along the sampling track all the time, stops at the sampling position of sample analyzer A for sampling, then continues to flow to the sampling position of sample analyzer B for sampling, and then returns from the return track. In the second sampling mode, after the sample stops at the sampling position of sample analyzer A for sampling, since it does not need to pass through the sampling position of sample analyzer B, it needs to transfer to the second section middle rotor track 31, re-transfer to the sampling track at the sample outlet end of the second section middle rotor track 31, and then return from the return track. In the third sampling mode, the sample does not need to pass through the sampling position of sample analyzer A, therefore, it transfers from the sampling track to the first section middle rotor track 31, re-transfers to the sampling track at the sample outlet end of the first section middle rotor track 31, continues to flow to the sampling position of sample analyzer B on the sampling track for sampling, and then returns from the return track.

[0033] In the above-mentioned second and third modes, the sample needs to be transferred from the sample suction track to the transfer track, and then transferred back to the sample suction track. The present embodiment adopts a track change component 4 for track change, and the track change component 4 includes a disc with a notch, which blocks the sample and can be rotated clockwise or counterclockwise. When it is necessary to change the track, rotate the disc clockwise so that the notch position clamps the test tube holder where the sample is located, and continue to rotate clockwise to change the sample from the sample suction track 1 to the transfer track 3, or change the sample from the transfer track 3 to the sample suction track 1. If it is not necessary to change the track, rotate the disc counterclockwise so that the notch position clamps the test tube holder where the sample is located, and continue to rotate counterclockwise to rotate the sample from one side of the disc to the other side, so that the sample continues to flow along the sample suction track 1.

[0034] In this embodiment, each section of the middle rotor track 31 is provided with a set of track changing components 4. According to the different positions of the track changing components, the first track changing component 41 is the track changing component 4 located at the sample inlet end of the middle rotor track 31, and the second track changing component 42 is the track changing component 4 located at the sample outlet end.

[0035] It can be seen from the above technical solutions that the online sample suction track system provided in this embodiment can connect multiple analytical instruments in series, with higher circulation efficiency and smaller footprint.

[0036] Reference Figure 3 In the structural schematic diagram shown, at the sample suction position of each sample analyzer, a sample suction blocking component 5 is provided on one side of the sample suction track 1, and the sample suction blocking component 5 is provided between the first track changing component 41 and the second track changing component 42, and is used to block the sample from staying. The sample suction blocking component 5 includes a disc with a gear, and each rotation of the disc by one angle can block a sample from staying.

[0037] In order to prevent sample deviation from affecting sample suction, a tube holding assembly 6 is further provided on one side of the sample suction rail 1. The tube holding assembly 6 is used to hold the sample. The tube holding assembly 6 includes two mutually meshing jaws. When one of the jaws is driven to rotate, the other jaw rotates toward each other due to the meshing effect, thereby clamping the sample.

[0038] The above-mentioned online sample suction track system is applied to the fully automatic pipeline sample processing system. However, when the pipeline sample processing system fails or is under maintenance, the online sample suction track system will not be available. In order to solve this problem, Figure 1 As shown in the structural schematic diagram, the online sample suction track system provided in this embodiment also includes: an offline sample adding track 7, which is connected to the return track 2 and is used for adding samples in an offline state; an offline sampling track 8, whose sample inlet end is connected to the sample suction track 1, and whose sample outlet end is connected to the offline sample adding track 7, and is used for sampling samples that have completed the sample suction in an offline state.

[0039] When problems occur in other modules of the fully automatic pipeline sample processing system, the operator can manually place the sample on the empty test tube holder of the offline sample adding track 7, and the sample enters the sample suction track 1 from the return track 2 for testing, thereby ensuring the availability of the online sample suction module to the greatest extent.

[0040] In the actual production of the assembly line, the track is usually made up of multiple sections. Common track shapes include T-rail, I-rail, L-rail, etc., and a track changing mechanism is added at the fork in the road to change the flow direction of the sample.

[0041] In this embodiment, the sample suction track 1 includes a sample injection track 11, a sample suction forward track 12, and an offline entry track 13 connected in sequence; the return track 2 includes a sample output track 21, a sample suction return track 22, and an offline exit track 23 connected in sequence; the sample injection track 11 and the sample output track 21 are connected in an offline state, the sample suction forward track 12, the sample suction return track 22, and the transfer track 3 have corresponding lengths, the offline sample addition track 7 is connected to the offline exit track 23, and the injection end of the offline sampling track 8 is connected to the offline entry track 13. There is a corresponding relationship in the length direction of the sample suction forward track 12, the middle rotor track 31, and the sample suction return track 22. In a scenario where multiple sample analyzers are set up, the number of the sample suction forward track 12, the middle rotor track 31, and the sample suction return track 22 is consistent with the number of sample analyzers, and they are all composed of multiple sections.

[0042] Reference Figure 4 As shown in the structural schematic diagram, a first blocking component 91 is provided at the connection between the offline entry track 13 and the offline sampling track 8. The first blocking component 91 is used to block the sample from staying so as to identify whether the sample is an offline sample. If so, the sample is controlled to flow to the offline sampling track 8.

[0043] Reference Figure 2 As shown in the structural schematic diagram, a second blocking component 92 is provided at the connection between the sample output track 21 and the sample input track 11. The second blocking component 92 is used to block the sample from staying so as to identify whether the sample is an offline sample. If so, the sample is controlled to flow to the sample suction track 1 and then return to the offline sampling track 8.

[0044] In this embodiment, the identification of offline samples can be barcode identification or RFID identification. Since RFID identification has the advantages of convenience, speed and reliability, RFID identification is preferred in this application.

[0045] Reference Figure 4 In the structural schematic diagram shown, a third blocking component 93 is provided at the connection between the offline sample adding track 7 and the return track to prevent the sample from staying. An empty test tube holder is pre-set on the offline sample adding track 7. When the online sample suction track system needs to be operated offline, the operator adds the sample on the empty test tube holder, and the sample is blocked by the third blocking component 93 before flowing into the return track 2. A rotating code scanning component is provided here, and the rotating code scanning component is used to scan the barcode on the surface of the sample to obtain sample information, such as name, test item, etc. In this embodiment, the sample information obtained by the rotating code scanning is associated with the test tube holder information, and the sample information and the test tube holder information are used as test information.

[0046] After scanning the code, the test tube holder passes through the offline exit track 23, the sample return track 22, and the sample exit track 21, and stops at the second blocking component 92. The RFID below reads the information of the test tube holder and determines that it is an offline test tube holder. The baffle of the track change mechanism is blocked, and the test tube holder turns left and flows into the sample input track 11 and the sample forward track 12. Figure 4 As shown in the structural diagram, after the sample is sucked, it enters the offline module from the offline entry track and stops at the first blocking component 91. The RFID below reads the information of the test tube holder and determines that it is an offline test tube holder. The blocking piece of the track change mechanism is blocked, and the test tube holder turns right and flows into the offline sampling track 8. The sample outlet end of the offline sampling track 8 is provided with a fourth blocking component 94, and the test tube holder stops at the fourth blocking component 94. The doctor takes the test tube away, and the fourth blocking component 94 is released, and the empty tube holder flows into the offline sample adding track 7.

[0047] In this embodiment, the first blocking assembly 91, the second blocking assembly 92, the third blocking assembly 93, and the fourth blocking assembly 94 have the same structure, and are mainly provided with two parallel push rods. When one of the push rods is driven to extend, the other push rod will run in the opposite direction, thereby realizing the function of blocking and releasing the test tube holder.

[0048] This embodiment also provides a pipeline analysis system, including Figure 1 An online sample suction track system provided by any one of the implementations.

[0049] In addition, the embodiment of the present application also provides a control method for an online sample suction track system, comprising the following steps:

[0050] Step 101, controlling the first track changing component to block the inflowing target sample and obtaining the test information of the target sample.

[0051] In this embodiment, after the target sample is put online, it corresponds to the test tube holder one by one. An RFID tag is set at the bottom of the test tube holder. By identifying the RFID tag, the test information of the target sample can be obtained. The test information includes sample information and test tube holder information. The sample information includes name, test items, etc. The test tube holder information includes the type of test tube holder, among which the types of test tube holders are mainly divided into online test tube holders and offline test tube holders. The offline test tube holder is only for offline samples, and the online test tube holder is only for online samples. The online test tube holder comes from the main track of the assembly line, and the offline test tube holder flows into the sample suction track through the offline sample adding track and the return track.

[0052] Step 102: judging whether the target sample needs to be sampled by the sample analyzer corresponding to the current middle rotor track according to the test information.

[0053] In this step, the sample analyzer corresponding to the middle rotor track actually refers to the sample analyzer installed on one side of the sample suction track corresponding to the middle rotor track. If the target sample needs to be sucked by the sample analyzer corresponding to the current middle rotor track, the operation of step 103 is performed, otherwise, the operation of step 104 is performed.

[0054] Step 103: If the target sample needs to be sampled by the sample analyzer corresponding to the current middle rotor track, it is directly released to complete the sample collection.

[0055] In this step, the sample flows to the sample suction blocking component, and the RFID under the sample suction blocking component reads the test tube holder information and transmits the information to the sample analyzer. The sample suction blocking component then rotates to release, and the sample continues to flow to the next sample suction blocking component. At the same time, the tube holding component starts to clamp the test tube, and then the sample suction needle of the sample analyzer completes the sample suction.

[0056] Step 104: If the target sample does not need to be sampled by the sample analyzer corresponding to the current middle rotor track, the first track change component changes the track of the target sample to the current middle rotor track.

[0057] Step 105 , at the sample exit end of the current middle rotor track, control the second track changing assembly to change the track of the target sample located on the middle rotor track to the sample suction track, or directly release the target sample located on the sample suction track.

[0058] This step involves two situations. The first is the target sample transferred from step 103. At this time, the second track changing component will directly release the target sample located on the sample suction track. The second is the target sample transferred from step 104. At this time, the second track changing component will change the target sample located on the middle rotor track to the sample suction track.

[0059] Step 106, the target sample enters the sample inlet end of the next middle rotor track from the sample outlet end of the current middle rotor track, and returns to execute the step of obtaining the test information of the target sample until the target sample flows out from the last middle rotor track.

[0060] Step 107: at the sample outlet end of the sample suction track, determine whether the target sample is an online sample.

[0061] In this step, the first blocking component is used to stop the sample, and the RFID identifies the test tube holder information to determine whether it is an online test tube holder or an offline test tube holder. If it is an online test tube holder, the sample on its surface is an online sample, and the operation of step 108 is continued; if it is an offline test tube holder, the sample on its surface is an offline sample, and the operation of step 109 is continued.

[0062] Step 108: If the target sample is an online sample, the target sample is controlled to enter the return track.

[0063] Step 109: If the target sample is not an online sample, the target sample is controlled to enter the offline sampling track, so that the target sample enters the return track via the offline sampling track and the offline sampling track.

[0064] Optionally, after controlling the target sample to enter the offline sampling track so that the target sample enters the return track via the offline sampling track and the offline sample adding track, the following steps are also included:

[0065] Step 1091, at the sample output end of the return track, determine whether the target sample is an online sample.

[0066] In this step, the second blocking component is used to stop the sample, and the RFID identifies the test tube holder information to determine whether it is an online test tube holder or an offline test tube holder. If it is an online test tube holder, continue to perform the operation of step 1092; if it is an offline test tube holder, continue to perform the operation of step 1093.

[0067] Step 1092, if yes, release it directly so that the target sample can enter the main track of the pipeline via the return track.

[0068] Step 1093, if not, control the sample to re-enter the sample suction track via the return track.

[0069] The above are merely embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application are included in the scope of the claims of the present application to be approved.
