In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. The components of the embodiments of the present disclosure, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the disclosure, provided in the accompanying drawings, is not intended to limit the scope of the disclosure, as claimed, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the disclosure without making creative efforts, shall fall within the protection scope of the disclosure.

Research shows that gene sequencing can analyze and determine the complete gene sequence, is favorable to predicting and preventing various diseases and is widely applied. In the gene sequencing process, various reagents are required to be added to the reaction chip to complete the gene sequencing. In this process, if a fluid path system corresponding to gene sequencing fails, the gene sequencing result may be affected. Therefore, it is very important to detect the liquid path system in real time during the gene sequencing process.

In the related art, after the gene sequencing task is completed, the fluid path system corresponding to the gene sequencing can be detected to determine whether the fluid path system has a fault.

Based on this, the fluid path system in the related art may be as shown in fig. 1. As shown in FIG. 1, the liquid path system may include a reagent selection module 11, a reaction chip 12, a pump unit 14, a detection module 13, a waste liquid tank 16, and a controller.

As can be seen from fig. 1, the liquid path system can arrange the detection module 13 in the liquid path pipeline connecting the pump unit 14 and the reagent selection module 11, and further, after the reagent selection module 11 and the pump unit 14 receive a reagent addition instruction sent by the controller, the target reagent can be transmitted to the reaction chip 12 through the liquid path pipeline. Thereafter, the reaction chip 12 may process the target reagent, and transmit the processed waste liquid to the pump unit 14 through the liquid path pipe. The pump unit 14 can then, after receiving the waste liquid, lead out the waste liquid.

According to the process, the detection module is not used in the gene sequencing process, so that the real-time detection of the existing liquid path system cannot be realized, and the liquid path system cannot be timely and effectively monitored under the condition that the liquid path system is leaked or blocked.

In the related art, when the fluid path system is to be detected, the controller sends a corresponding detection instruction to the pump set and the reagent selection module to detect the fluid path system after the gene sequencing process is completed.

However, a complete gene sequencing process takes about 30 hours, and if the liquid path system is lack of or has no sample, the pump set and the reagent selection module can be operated without liquid, which may damage the equipment and increase the maintenance cost. Moreover, if the fluid path system fails during the gene sequencing process, the gene sequencing result may be affected, thereby causing waste of the sample.

When the flow resistance of the liquid path system is detected after the gene sequencing process is completed, when it is usually necessary to flow the waste liquid into the pump set, the joint connecting the liquid path pipeline and the pump set is removed (for example, as shown in fig. 2, the joint connecting the liquid path pipeline corresponding to the liquid outlet of the reaction path 1 and the pump set port 1 needs to be removed), and the joint is connected to one end of the detection module 13 (for example, as shown in fig. 2, the joint is connected to the lower joint position of the detection module 13-1), so that the waste liquid can flow through the detection module 13-1. In the above embodiment, when the flow resistance of the liquid path system is detected, the joint needs to be repeatedly disassembled, so that the joint is easily damaged, a large amount of human resources and time cost are wasted, and the use performance of the liquid path system is also influenced.

Meanwhile, in the above embodiment, the waste liquid can flow through the liquid path channel shown by the dotted line, so that when impurities exist in the liquid path system, the impurities can easily enter the liquid path channel shown by the dotted line and further enter the pump group, and the pump group is easily damaged. In this case, not only the maintenance cost of the liquid path system is increased, but also the gene sequencing result is easily affected.

Based on the research, the present disclosure provides a liquid path monitoring device, a gene sequencer and a gene sequencing device. The liquid path monitoring device provided by the embodiment of the disclosure can comprise a reagent selection module, a reaction chip, a detection module, a pump set and a controller. The detection module can be arranged in a liquid pipeline between the reaction chip and the pump set, so that the flow resistance of flowing waste liquid can be detected through the detection module, and the flow resistance detection result is sent to the controller. Then, in a case where it is determined that the flow resistance detection is abnormal based on the flow resistance detection result, a pressure detection instruction may be sent to the pump group to perform a pressure test on the liquid path piping of the liquid path monitoring apparatus.

For the convenience of understanding the present embodiment, a detailed description will be given to a fluid path monitoring device disclosed in the embodiments of the present disclosure.

Then, the reagent selection valve can transfer the target reagent to the reaction chip through the liquid pipeline.

And then, the treated waste liquid can be transmitted to the liquid outlets corresponding to the reaction passages, and the treated waste liquid is transmitted to the liquid passage pipeline through the corresponding liquid outlets. At this time, the other end of the waste liquid pipe is connected to a pump group.

In the embodiment of the present disclosure, a detection module may be disposed in a liquid path pipeline connecting the liquid outlet and the pump set, and flow resistance detection may be performed on the waste liquid flowing through the detection module based on the detection module. Wherein the detection module may be used to indicate a detection device, which may be a pressure sensor, for example.

The detection module 300 is configured to perform flow resistance detection on the flowing waste liquid, and send a flow resistance detection result to the controller 500.

In the embodiment of the disclosure, after the flow resistance detection is performed on the waste liquid flowing through the detection module based on the detection module, the detected flow resistance detection result may be sent to the controller.

The controller 500 is configured to send a pressure test command to the pump set 400 and a liquid feed stop command to the reagent selection module 100 and the pump set 400 in case of determining that the flow resistance detection is abnormal based on the flow resistance detection result.

In the embodiment of the disclosure, after the controller receives the flow resistance detection result, the flow resistance detection result may be compared with a preset detection result, and in a case that it is determined based on the comparison result that the flow resistance detection result is not identical to the preset detection result, it indicates that the flow resistance detection of the fluid path monitoring device is abnormal.

At this point, the controller may send a stop feed command to the reagent selection module and to the pump set to cause the pump set and reagent selection module to stop delivering the target reagent. Meanwhile, a pressure test instruction can be sent to the pump unit, so that the pump unit transmits pressure air to the liquid path pipeline in the liquid path monitoring device, and pressure test can be performed on the liquid path pipeline in the liquid path monitoring device.

The pump unit 400 is configured to control the reagent selection module 100 to obtain a target reagent after receiving a reagent addition instruction sent by the controller 500; leading out the waste liquid; and after receiving a pressure test command sent by the controller 500, the pressure test command transmits pressure air to the reagent selection module 100, so as to perform pressure test on the liquid pipeline through the detection module 300.

In the embodiment of the present disclosure, a first port of the plurality of ports included in the pump set selection valve may be connected to a liquid path pipe, and at this time, the other end of the liquid path pipe is connected to a liquid outlet of the reaction chip. After the pump set receives the reagent addition instruction, the reagent selection module can be controlled to obtain the target reagent based on a pressure control module in the pump set and receive waste liquid based on the first port. The waste liquid may then be directed out through a third port of the plurality of ports comprised by the pump set selection valve.

The reagent selection valve in fig. 5 comprises 10 reagent selection ports, wherein the 10 reagent selection ports are "C1", "C2", "C3", …, "C9" and "C10" in fig. 5, respectively, and one common port, which may be "COM" in fig. 5.

Wherein the reagent selection port is for delivering the target reagent to the common port after receiving the target reagent. For example, as shown in fig. 5, assuming that the reagent selection port "C6" is used to receive a target reagent, at this time, the reagent selection port "C6" (i.e., may be understood as PA or PB in fig. 4) may communicate with the common port "COM" (i.e., may be understood as VPA or VPB in fig. 4) and transfer the received target reagent into the common port "COM" (i.e., may be understood as VPA or VPB in fig. 4).

In the disclosed embodiment, the common port is used for transmitting the received target reagent to the reaction chip through the liquid channel pipeline. At this time, the common port may be connected to the liquid inlet of the reaction chip through a liquid channel.
