[0042] Please continue to refer to Figure 1As shown, the first L-shaped circulation pipe 22 is respectively connected to the air ejector 21 and the first chamber 11. The air in the first chamber 11 enters the first L-shaped circulation pipe 22 from the side and then flows upward, and is discharged outward from the top of the sandwich partition 13 through the air ejector 21.
[0043] Furthermore, a first air outlet is provided on the side of the first chamber 11. The first L-shaped circulation pipe 22 is connected to the first air outlet, and the air in the first chamber 11 enters the first L-shaped circulation pipe 22 from the side through the first air outlet.
[0044] Please continue to refer to Figure 1 As shown, the second L-shaped circulation pipe 23 is respectively connected to the air ejector 21 and the second chamber 12. The air in the second chamber 12 enters the second L-shaped circulation pipe 23 from the side and then flows upward, and is discharged outward from the top of the sandwich partition 13 through the air ejector 21.

[0046] Figure 2 It shows the gas flow direction in the experimental chamber of the mobile biological experimental chamber device provided by the embodiment of the present application. In Figure 1 and Figure 2 , the vertical pipe portions of the first L-shaped circulation pipe 22 and the second L-shaped circulation pipe 23 can be horizontally arranged side by side in the sandwich partition 13. Please refer to Figure 1 and Figure 2 As shown, after the gas in the first chamber 11 enters the first L-shaped circulation pipe 22 from the first air outlet on the side, it enters the air ejector 21 along the pipe direction upward and is discharged out of the chamber after being filtered by the air ejector 21. Similarly, after the gas in the second chamber 12 enters the second L-shaped circulation pipe 23 from the second air outlet on the side, it enters the air ejector 21 along the pipe direction upward and is discharged out of the chamber after being filtered by the air ejector 21.
[0047] Figure 3A It shows the front view of the mobile biological experimental chamber device provided by another embodiment of the present application. Figure 3B It shows the gas flow direction in the experimental chamber of the mobile biological experimental chamber device provided by another embodiment of the present application. In Figure 3A and Figure 3B , the vertical pipe portions of the first L-shaped circulation pipe 22 and the second L-shaped circulation pipe 23 can be arranged side by side one after another in the sandwich partition 13. Please refer to Figure 3A andFigure 3B As shown, after the gas in the first chamber 11 enters the first L-shaped circulation pipeline 22 from the first air outlet on the side, it is discharged upward along the pipeline direction. Similarly, after the gas in the second chamber 12 enters the second L-shaped circulation pipeline 23 from the second air outlet on the side, it is discharged upward along the pipeline direction.
[0048] Further, please continue to refer to Figure 1 As shown, a first purifier 24 is provided at the top of the first chamber 11, and the outside air enters the first chamber 11 after being purified by the first purifier 24. At the same time, a second purifier 25 is provided at the top of the second chamber 12, and the outside air enters the second chamber 12 after being purified by the second purifier 25.
[0049] Please continue to refer to Figure 1 and Figure 2 As shown, in order to achieve the gas circulation in the experimental chamber 1 and receive the outside air into the chamber, but the outside air carries a lot of gas particles, which is likely to affect the biological samples. Therefore, it is necessary to enter the first chamber 11 and the second chamber 12 respectively after being purified by the first purifier 24 and the second purifier 25.
[0050] It should be noted that after the gas in the first chamber 11 and the second chamber 12 is discharged out of the chamber through the air expeller 21, it can also enter the experimental chamber 1 again as the outside air. That is, the mobile biological experimental chamber device provided by the embodiments of the present application can effectively achieve the gas circulation inside and outside the experimental chamber and ensure the cleanliness of the experimental environment.
[0051] Specifically, a pressure detection device is further provided in the experimental chamber 1, and the pressure detection device includes a first pressure detection unit provided at the top of the first chamber 11 and a second pressure detection unit provided at the top of the second chamber 12. Through the pressure detection device, the air pressure in the chamber can be effectively detected and monitored to provide the required air pressure conditions for the experiment.
[0052] Taking the PCR experiment as an example, during the experiment, a positive pressure chamber for sample extraction and a negative pressure chamber for amplification and sequencing need to be set up separately. In this way, when extracting the sample, it is possible to avoid external air entering the chamber and contaminating the sample. At the same time, during amplification and sequencing, it is possible to avoid the leakage of pollutants generated by PCR to the outside, which may affect the environment and personnel. Therefore, when the mobile biological experiment chamber device provided by the embodiments of the present application is applicable to the PCR experiment, the air pressure condition of the first chamber 11 can be set to positive pressure for sample extraction, and the air pressure condition of the second chamber 12 can be set to negative pressure for amplification and sequencing. At this time, the first air pressure detection unit can monitor the air pressure condition of the first chamber 11 and adjust it in a timely manner to keep the air pressure in the first chamber 11 stable at the positive pressure set value. Similarly, the second air pressure detection unit can monitor the air pressure condition of the second chamber 12 and adjust it in a timely manner to keep the air pressure in the second chamber 12 stable at the negative pressure set value.
[0053] In some embodiments, a transfer device is included in the experiment chamber 1, and the transfer device can transfer the sample in the first chamber 11 to the second chamber 12. Taking the above-mentioned PCR experiment as an example, the first chamber 11 is a positive pressure chamber. After the sample extraction is completed in the first chamber 11, it needs to be transferred to the second chamber 12 with negative pressure for the amplification and sequencing experiment. At this time, the transfer device can be used to move the sample from the first chamber 11 to the second chamber 12, that is, the transfer device realizes the one-way transfer from the positive pressure chamber to the negative pressure chamber.
[0054] Furthermore, the transfer device includes a placement table and two transfer windows. The carrier table can move from one transfer window to the other transfer window. The two transfer windows are respectively arranged below the first chamber 11 and the second chamber 12, so as to realize the transfer of the biological sample on the carrier table.
[0055] Furthermore, the transfer window can be blocked by a baffle. When the baffle is moved away from the transfer window, the placement table communicates with the first chamber 11 or the second chamber 12 through the transfer window. In this way, a microplate containing the sample and / or reagent can be clamped by a clamp and passed through the transfer window located below the first chamber 11 and placed on the placement table. The placement table moves from this transfer window to the transfer window located below the second chamber 12. At this time, the baffle is moved away, and the clamp in the second chamber 12 extends downward, clamps the biological sample from the lower transfer window, and returns to the second chamber 12 for amplification and detection processes.
[0056] In some embodiments, the mobile biological experiment chamber device provided by the present application is as Figure 4 shown. In Figure 4In the structure shown, the first L-shaped circulation pipe 22 and the second L-shaped circulation pipe 23 connected to the air ejector 21 are located in the rear inner wall of the first chamber 11, and are respectively connected to the first air outlet on the side of the first chamber 11 and the second air outlet on the side of the second chamber 12 (not shown in the figure), so as to discharge the air output from the side of the first chamber 11 and the air output from the side of the second chamber 12 upward from the top along the first L-shaped circulation pipe 22 and the second L-shaped circulation pipe 23 out of the experimental chamber, thereby discharging pollutants and gases such as aerosols generated by biological experiments to the designated area at the top, reducing interference with the experimental environment and personnel.
[0057] Please continue to refer to Figure 4 As shown, the mobile biological experimental chamber device provided by the present application can be arranged on the support cabinet 3. The support cabinet 3 is a frame structure formed by overlapping multiple metal materials. The parallel parts of the first L-shaped circulation pipe and the second L-shaped circulation pipe can be arranged in the frame structure, and thus are located below the experimental chamber body. This can save the required space of the device and also facilitate the maintenance of the pipeline. Among them, for the metal material, metals such as aluminum and copper can be selected, and the present application does not make any restrictions on this.
[0058] In addition, please refer to Figure 4 As shown, moving devices 31 are provided at the corners of the support cabinet 3. In some embodiments, the moving devices 31 include universal moving wheels, so as to realize that the mobile biological experimental chamber device provided by the present application can be freely moved through the universal moving wheels, thereby improving the practicability.
[0059] In addition, the mobile biological experimental chamber device provided by the present application can also be provided with a display device. The display device includes a display screen, which can be used to display the experimental results in the experimental chamber 1. At this time, the experimental results can be automatically read and retained through an automatic program, without manual recording, further reducing the experimental cost. In addition, for the experimental environment in the experimental chamber 1, it can also be directly controlled through the display device, without entering the experimental chamber for manual adjustment, realizing full-automatic control in all aspects.
[0060] In the above embodiments, the mobile biological experimental chamber device provided by the present application can also be provided with an ultraviolet disinfection device, a monitoring device and a lighting device to further better disinfect and monitor the experimental environment in the chamber and improve the safety of biological experiments. The specific types and models of the ultraviolet disinfection device, the monitoring device and the lighting device are not limited by the present application.
[0061] The descriptions of the processes or structures corresponding to the above respective drawings have their own emphases. For the parts not detailed in a certain process or structure, reference can be made to the relevant descriptions of other processes or structures.
