[0033] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, the cascade device based on biological detection of the present invention includes connectors 11, 12, an electrical control module 13, a fluid control module 14 and a functional module 15;

[0035] The electrical control module 13 is used to connect with other cascade devices and / or a host control machine through the connectors 11 and 12 to realize electrical signal processing and transmission between devices and real-time communication and synchronous control of data. The connector 11 is used to connect with the cascade device or the host control machine of the previous level, and the connector 12 is used to connect with the cascade device of the next level. The connectors 11 and 12 are connected by magnetic attraction, which makes the connection of multiple cascade devices easier and faster.

[0036] The fluid control module 14 is used for fluid flow control between cascaded devices and / or within cascaded devices. For example, it is responsible for automatic extraction and addition of sample liquid and detection control of the entire process. In the cascade state, the one-way valve structure and precise fluid pipeline design ensure smooth flow of sample liquid between devices and within the device.

[0037] The functional module 15 is used to control the power supply of the electrodes of the functional module 15 and the flow direction of the fluid according to the electrical control instructions of the electrical control module 13 and the flow control instructions of the fluid control module 14, so as to perform the corresponding biological detection function. For example, a high-precision sensor is used to analyze the product after the sample liquid reacts, and it is responsible for collecting and obtaining a variety of characteristic information including electrical signals, optical signals, etc., and performing efficient and accurate signal processing on the collected signals, so as to accurately judge the positive and negative results of the detection sample. Sample amplification is performed by adding sample liquid and reaction liquid to the reaction area of ​​the functional module 15, magnetic beads are enriched in the magnetic absorption area of ​​the functional module 15, and biological detection is performed in the detection area of ​​the functional module 15. In addition, different functional modules can be configured inside the cascade device according to the detection requirements, such as sample pretreatment module, temperature control module, etc. These functional modules also adopt modular design, which is convenient for flexible configuration and replacement according to actual application requirements.

[0038] In one embodiment of the present invention, Figure 2A and 2B As shown, the cascade device also includes a shell, and the electrical control module 13, the fluid control module 14 and the functional module 15 are arranged in the shell, and a cascade splicing structure 21 is arranged on the side of the shell. By combining and connecting the cascade splicing structures 21 of the two cascade devices, the two cascade devices are fixedly positioned. The electrical circuits and fluid pipelines of the electrical control module 13, the fluid control module 14 and the functional module 15 are all arranged in the shell, and the connection of all electrical circuits is achieved through connectors, which further simplifies the line connection between the cascade devices. In addition, by arranging the cascade splicing structure on the side of the shell, two cascade devices that need to be connected can be conveniently and reliably and stably fixed and positioned, reducing the occupied space after the cascade devices are connected.

[0039] In one embodiment of the present invention, the cascade splicing structure 21 includes a guide positioning rail 211 and a guide groove 212. The guide positioning rail 211 is arranged on the side of the shell of one of the cascade devices in the vertical direction, and the guide groove 212 is arranged on the side of the shell of another cascade device in the vertical direction. The two cascade devices are fixedly positioned by the matching connection between the guide positioning rail 211 and the guide groove 212. The guide positioning rail 211 and the guide groove 212 can be respectively arranged on two opposite sides of the same cascade device, so that other cascade devices or upper control machines can be connected both upstream and downstream of the cascade device. For example, in Figure 2A A guide and positioning slide rail 211 is provided on the right side of the housing. Figure 2B A guide groove 212 is provided on the left side of the housing.

[0040] In one embodiment of the present invention, the connector includes a magnetic male head 111 and a magnetic female seat 112. The magnetic male head 111 is arranged on the side of the shell of a cascade device below the guide positioning slide rail 211, and the magnetic male head 111 protrudes outward from the side of the shell; the magnetic female seat 112 is arranged on the side of the shell of another cascade device below the guide groove 212. When the two cascade devices are connected through the cascade splicing structure 21, the magnetic male head 111 and the magnetic female seat 112 are also connected together, so that the two cascade devices are spliced ​​and positioned and electrically connected at the same time. The arrangement of the connector and the magnetic splicing structure is as above, so that the magnetic interface can be connected while the two cascade devices are fixed and positioned, which further simplifies the connection of the two cascade devices. For the two cascade devices connected in the above manner, see the attached Figure 3 , which not only simplifies the connection complexity, but also reduces the space occupied by the equipment.

[0042] In one embodiment of the present invention, the functional module includes at least one of an injection area, a reaction area, a magnetic attraction area, a detection area, and a waste liquid area. Different functional modules can be configured according to different needs of biological detection. For example, biological immune detection is configured with an injection area, a reaction area, and a detection area. Nucleic acid detection is configured with an injection area, a reaction area, a magnetic attraction area, a detection area, and a waste liquid area, etc. Different functional modules are configured according to different application needs to make the biological detection configuration more flexible and convenient. In addition, the various areas of the above-mentioned functional modules can be integrated in the functional modules of the same cascade device, or can be independently arranged in the functional modules of different cascade devices.

[0043] In one embodiment of the present invention, the multiple cascade devices include a cascade host 43 and multiple cascade slaves 44, the cascade host 43 and the multiple cascade slaves 44 are serially connected through a connector, and the functional modules of each cascade slave 44 are the same. In this embodiment, by configuring each functional module as the same module with the same function, the upper control machine can configure and set the execution parameters of all functional modules at the same time, without the need to configure each cascade slave 44 separately, thereby simplifying the configuration method and improving efficiency. Each detection device can independently complete a specific biological detection process, and can be quickly deployed according to actual needs to form a large-scale cascade detection system, realize ultra-high throughput detection under unified scheduling management, complete rapid and efficient processing of biological samples, and improve detection efficiency.

[0044] In one embodiment of the present invention, the multiple cascade devices include a cascade host 43 and multiple cascade slaves 44, the cascade host 43 and the multiple cascade slaves 44 are serially connected through a connector, the multiple cascade slaves 44 are serially connected in sequence according to the biological detection process, and the functional modules of each cascade slave 44 are independently configured according to each process of the biological detection. This embodiment can meet different detection needs by configuring the parameters of the functional modules of the cascade slaves 44 separately, thereby improving the flexibility of biological detection. According to different detection task requirements, it is flexible to select and configure pre-processing function devices, reaction function devices, detection function devices, or add other functional modules necessary for the biological detection process to form a diversified cascade detection system solution to meet the functional needs of a specific biological detection process. Each functional device is cascaded and spliced ​​according to the detection process, and is started sequentially under unified scheduling management to complete the detection task.

[0045] like Figure 5 As shown, the cascade method based on biological detection of the present invention utilizes the above-mentioned cascade system, and the cascade method includes the following steps:

[0046] Step S510: configuring a plurality of cascade devices according to biological detection functions, and sequentially connecting the plurality of cascade devices in series according to biological detection procedures;

[0047] Step S520: configuring a power supply to be connected to a cascade host in a plurality of cascade devices;

[0048] Step S530: configuring the upper control machine to communicate with the cascade host;

[0049] Step S540: sending a control instruction to the cascade host and the cascade host distributes the control instruction to other cascade slaves;

[0050] Step S550: The cascade host and multiple cascade slaves configure the working parameters of their respective electrical control modules, fluid control modules and functional modules according to the control instructions, and perform corresponding biological detection.

[0051] According to the requirements of the inspection task, select the appropriate modular inspection device and determine the type and quantity of functional modules required. Prepare the necessary tools and materials, including connecting harnesses, power supplies, and host computers.

[0052] Specifically, 1) each modular detection device is preliminarily spliced ​​together through a dovetail structure or other structural means to ensure that each device is tightly connected and spliced ​​in place.

[0053] 2) Use magnetic connectors to connect the electrical and communication interfaces of each device. During the connection process, the freedom of the fixed part of the magnetic interface can be used to easily achieve rapid adsorption and automatic alignment of the male and female magnetic interfaces.

[0054] 3) Set one of the detection devices as the host, connect it to the power supply and the host computer through the wiring harness, and then configure the detection device through the host computer to set the detection parameters, communication protocol, etc.

[0055] 4) The host computer can transmit instructions to each slave through the magnetic interface to achieve unified scheduling and control management of the entire cascade system.

[0056] 5) After completing the system configuration, carry out overall debugging to check whether the power supply and communication between the devices are normal, whether the functional modules inside the devices are normal, such as whether the electrical control is accurate, whether the fluid pipelines are unobstructed, etc.

[0057] 6) After debugging, start the cascade system. Under unified scheduling and control, each device and module works together to complete the detection process.

[0058] 7) During use, the modular detection device should be regularly inspected and maintained to ensure the normal operation of all components of the device. If you need to add new functional modules or upgrade existing modules, you only need to replace or upgrade the corresponding modules and reconnect and configure them through the magnetic interface, without the need for large-scale transformation of the entire cascade system.

[0059] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0061] 2.

At the same time, the modular design also simplifies the maintenance process and improves the reliability and maintainability of the system.

[0062] 3. Enhanced scalability and adaptability: The modular detection device of the present invention not only supports the expansion of the same type of devices, but also can meet diverse detection needs by designing different functional modules, thereby expanding the detection range.

[0063] 4. Simplify the operation process: The use of magnetic connectors eliminates the complex wiring harness connection of traditional detection devices, making the structural splicing and power supply communication between devices simple and fast. Users can quickly deploy and cascade the device without complicated wiring operations, greatly reducing the difficulty and time cost of operation.
