In the prior art, most molecular diagnostic instruments are semi-automatic instruments. When performing molecular diagnosis, manual participation in operations such as sample transfer is required.

In addition, the sample processing space and the detection space are independently arranged on the base frame 21, and the detection module 25 includes a detection chamber 251 for sealing detection of the extract, adopting a double physical isolation method, with a reasonable structure and good sealing performance, avoiding contamination problems caused by overflow of amplification products during the detection process, improving detection accuracy and reliability, and ensuring the life, health and safety of operators.
[0086] The fully automatic molecular diagnosis integrated device can be used for nucleic acid molecule detection or protein molecule detection, but the present invention is not limited thereto. When the fully automatic molecular diagnosis integrated device is used for nucleic acid molecule detection, the detection module can be a PCR amplification detection module.
[0087] Optionally, the detection module 25 may be provided with a plurality of detection chambers 251 arranged side by side and capable of independent detection, and each detection chamber 251 is provided with a plurality of detection positions.

In this way, 16 samples can be detected simultaneously, and the detection efficiency is high. And each detection chamber 251 is independently sealed and independently detected, avoiding the cross contamination problem caused by the overflow of the amplification product during the detection process, and ensuring the accuracy and reliability of the detection. In addition, during the detection process, when an emergency occurs and a special queue-jumping detection is required for the emergency sample, there is no need to shut down the entire line, and a part of the detection chamber 251 can be used for special detection purposes, while the other part of the detection chamber 251 does not need to be shut down, and the detection process continues, making the detection process more reasonable, and the sample can be injected and tested at any time, with stronger flexibility and higher detection efficiency. Among them, it should be noted that the detection module 25 can be provided with 2, 3, 5, 6 or even more detection chambers 251, etc., and each detection chamber 251 is provided with 2, 3, 5, 6 or even more detection positions, etc., and the present invention is not limited to this.
[0088] Furthermore, the fully automatic molecular diagnosis integrated device also includes a closed housing 3, and the base frame 21 is arranged in the housing 3. The housing 3 is mainly isolated from the outside world to prevent pollutants from spilling out. The housing 3 can be provided with a hatch, an observation window, a touch screen and other external interfaces. Specifically, Figure 2 As shown, the body shell 3 includes a shell sheet metal 31, an observation window 35, a touch screen 37, a sample tube inlet and outlet cabin door 32, a consumables inlet and outlet cabin door 33 and a reaction tube inlet and outlet cabin door 34.

[0089] Furthermore, the fully automatic molecular diagnosis integrated device may also include a sample processing space laminar flow system 32 disposed on the top plate of the body shell 3 aligned with the sample processing space, and the sample processing space laminar flow system 32 is used to form a negative pressure in the sample processing space inside the body shell 3 to prevent the internal contaminated airflow from flowing out without being filtered. The sample processing space laminar flow system includes a high-power sample processing space centrifugal fan and a sample processing space filter (not shown in the figure), etc. The sample processing space filter is disposed at the air inlet of the sample processing space centrifugal fan, so that a negative pressure can be formed in the sample processing space inside the body shell 3, ensuring that the airflow enters the sample processing space inside the body shell 3 from the outside, and flows out only through the sample processing space filter, preventing the contaminated airflow in the sample processing space from flowing out of the device without being filtered at other gap positions.
[0090] In addition, the fully automatic molecular diagnostic integrated device may also include a detection space laminar flow system arranged on the top plate of the body shell 3 that is aligned with the detection space, and the detection space laminar flow system and the sample processing space laminar flow system 32 are independently arranged.

The detection space laminar flow system includes a high-power detection space centrifugal fan and a detection space filter (not shown in the figure), etc. The detection space filter is arranged at the air inlet of the detection space centrifugal fan, so that a negative pressure can be formed in the detection space inside the body shell 3, ensuring that the airflow enters the detection space inside the body shell 3 from the outside, and only flows out through the detection space filter, preventing the contaminated airflow in the detection space from flowing out of the device without filtering at other gap positions.
[0091] In addition, the fully automatic molecular diagnostic integrated device may also include a first sensor, a second sensor and a controller, wherein the first sensor is used to detect the air pressure in the sample processing space, and the second sensor is used to detect the air pressure in the detection space. The controller is respectively connected to the first sensor, the second sensor, the centrifugal fan in the sample processing space, and the centrifugal fan in the detection space. When the air pressure detected by the second sensor is greater than the air pressure detected by the first sensor, the controller can control the centrifugal fan in the detection space to increase the speed to reduce the air pressure in the detection space, thereby preventing the gas in the detection space from flowing into the sample processing space, thereby further improving the protection performance of the equipment.
[0092] Alternatively, if Figure 3 As shown, the base frame 21 includes an upper support portion and a lower support portion 211, the upper support portion is located at the upper part of the base frame 21, and the lower support portion 211 is located at the lower part of the base frame 21 and is used to support the upper support portion. The left and right sides of the upper support portion are the table portion 212 and the bracket portion 213, respectively. The upper part of the table portion 212 defines the sample processing space, and the upper part of the bracket portion 213 defines the detection space. The sample cupping module 22, the sample extraction module 23 and the system construction module 24 are arranged in the sample processing space on the table portion 212, and the detection module 25 is arranged in the detection space on the bracket portion 213. In this way, the structure of the fully automatic molecular diagnostic integrated device can be made more reasonable and compact. Among them, the base frame 21 is composed of aluminum profiles, table aluminum fine plates, pillars, etc., which mainly play the role of supporting and fixing other functional modules.
[0093] In addition, the sample cupping module 22 may include a sample tube loading carrier 221, a sample tube barcode scanner 222, a clamping unit 227, a first motion unit 225, a second motion unit 226, a consumables unit 228, and a Tip head waste bin 229.

The sample tube barcode scanner 222, the sample tube barcode scanner 222 and the clamping unit 227 are arranged on the table portion 212, located at the lower part of the sample processing space and below the first motion unit 225. The consumable unit 228 is arranged on the table portion 212, located at the lower part of the sample processing space and below the second motion unit 226, and the Tip head waste trash can 229 is arranged under the table portion 212. The sample tube injection carrier 221 is located between the sample tube barcode scanner 222 and the clamping unit 227. In this way, the structure of the sample cup module 22 can be made more reasonable and compact, and the detection efficiency is higher.

[0095] In addition, the sample tube loading carrier 221 can adopt a pull-out type loading, and the sample tube barcode scanner 222 is placed on the left side of the sample tube loading carrier 221. During the pushing process of the sample tube loading carrier 221, the sample tube barcode scanner 222 captures the sample tube information and completes the barcode scanning function. Driven by the first motion unit 225, the opening cover mechanical claw 223 realizes the X-axis, Y-axis, and Z-axis movement of the opening cover mechanical claw 223, moves to the position of the specified sample tube, and clamps the sample tube. The clamping unit 227 mainly realizes the clamping of the sample tube during the opening and closing of the cover, and adopts flexible fingers to realize the clamping of different sample tubes.

During the working process, after the sample tube injection carrier 221 moves to the specified position, the lid opening robot claw 223 moves to the specified position of the sample tube through the XYZ three-axis, the robot claw opens, clamps the sample tube, lifts it and moves to the position of the clamping unit 227, the clamping module acts to clamp the sample tube, the lid opening robot claw 223 rotates, and opens the sample tube cover. At the same time, the pipette pump, driven by the second motion unit 226, moves to the position of the consumable unit 228 to press the Tip head, then moves to the clamping unit 227, absorbs the sample liquid, and then moves to the sample extraction module 23 to complete the injection. After the injection is completed, the pipette pump moves to the Tip waste bin 229 to complete the drop of the Tip head into the trash can, and the sample cupping function is completed.
[0096] Among them, the sample extraction module 23 uses the upper adsorption magnetic bead method and the magnetic rod movement method to realize nucleic acid extraction, which has the advantages of fast speed and simple structure. The distance between the magnetic rods can be reasonably designed to prevent contamination during the extraction process. The pre-packaged 96-well deep-well plate is encapsulated with lysate, washing solution and other extraction reagents. The sample solution completed in the cup is injected into the sample hole of the deep-well plate, and the deep-well plate is pushed into the module. The motor drives the magnetic rod / magnetic rod sleeve to move up and down and left and right. The cleavage and purification of nucleic acids are realized through repeated combination and separation of the magnetic rod and nucleic acid.
