The second generator 44 is a vehicle-mounted portable 220V AC generator.

[0028] The self-propelled biosafety laboratory provided by the present invention is a biological laboratory that is modified based on a mature diesel or electric bus platform and meets standard specifications. The whole vehicle is divided into a driving room and a laboratory room 2, and a large amount of space is reserved for other emergency backup materials, etc. The size and position of the partition space can be adjusted as needed. The laboratory room 2 is divided into a reagent preparation room 3, a specimen preparation room 4, an amplification analysis room 5 and a sterilization room 15. A buffer room and a corresponding transfer window are set between each functional area; each laboratory room 2 is equipped with different detection instruments and equipment according to different detection requirements, so that it has the ability to detect nucleic acid specimens.

[0029] The various testing instruments and equipment equipped in the above-mentioned functional rooms are all existing mature equipment. For example, in the reagent preparation room 3, the reagents and clean workbench required for nucleic acid specimen testing are prepared in advance through a medical refrigerator; in the specimen preparation room 4, the centrifuge, extractor and medical refrigerator and other equipment required for nucleic acid specimen preparation are set up; in the amplification analysis room 5, the amplification instrument used for specimen analysis and the printer for printing reports and other equipment are set up; we will not go into details here.

[0030] It can realize rapid qualitative and quantitative detection of COVID-19 samples, and has outstanding features such as flexible mobility, rapid response, safety and reliability, and economical and practical. It is not restricted by location. In the event of an epidemic, it can quickly reach destinations including remote towns to carry out testing, minimize the flow of patients, reduce the risk of pathogen spread, and effectively control the epidemic. It can achieve "quick decision-making, faster response, and faster control", effectively solve the current situation of insufficient mobility of nucleic acid specimen detection capabilities, alleviate medical pressure, and truly realize the requirements of "joint prevention and control".

[0031] like Figure 4 As shown, the power distribution structure provided by the present invention meets all power needs of the mobile biosafety mobile laboratory, including lighting, ventilation and all instruments and equipment required for experimental testing in the laboratory room 2. Three power generation measures are set up, namely, external mains power, self-generation and backup power supply 46, to ensure that all instruments and specimens in the mobile laboratory are in effective working and protection state whether at the collection point or on the road. It improves the environmental needs of nucleic acid testing and improves the ability to prevent and control the epidemic.

[0032] In places where there is city power, the city power interface 45 is used to supply power to the vehicle-mounted UPS 50, and after voltage stabilization by the vehicle-mounted UPS 50, power is supplied to the entire self-propelled biosafety laboratory through the high-voltage distribution box 49.

[0033] When there is no mains electricity, a portable 220V AC generator can be used to generate electricity, which can ensure long-term power supply for the self-propelled biosafety laboratory. And at this time, it can be moved to a place with mains electricity.

[0034] When the bus is moving, the engine runs to drive the on-board 24V DC generator to generate electricity, which is protected by the low-voltage distribution box 48, inverted into 220V by the 220V inverter 47, and then stabilized by the on-board UPS 50. After that, the high-voltage distribution box 49 provides reliable power to the refrigerator containing medical reagents and other medical equipment that requires a stable power supply. At the same time, the on-board portable 220V AC generator charges the on-board UPS 50 so that the on-board UPS 50 has sufficient power once the vehicle stops running.

[0035] The power distribution room 42 also includes a backup power supply 46 for supplying power to the vehicle-mounted UPS 50. When the vehicle-mounted 24V DC generator and the vehicle-mounted portable 220V AC generator fail to work, the backup power supply 46 can also provide reliable power for refrigerators containing medical reagents and other medical equipment that require a stable power supply, further ensuring the reliability of the test results of various specimens and related instruments and equipment. The backup power supply 46 is a plurality of energy storage batteries connected in series to form a 220V voltage.

In this embodiment, the temperature-controlled ventilation equipment room 41 is provided with some ventilation equipment such as a fresh air fan, a filter, an exhaust fan, and an air conditioner.

[0037] At the same time, the reagent preparation room 3, the specimen preparation room 4, the amplification analysis room 5 and the second buffer room 7 are independently supplied with and exhausted through their own independently set fresh air systems, which effectively ensures that there will be no cross infection in the reagent preparation room 3, the specimen preparation room 4, the amplification analysis room 5 and the sterilization room 15, and ensures that the air supply and exhaust of each functional room can be controlled separately to save energy. The fresh air blower and filter are ventilation equipment already available on the market, and will not be described here.

[0038] like Figure 2 As shown, in this embodiment, a specimen transfer window 18 for receiving specimens is provided on the side wall of the specimen preparation room 4. A first safety door 9 for entering and exiting is provided on the side wall of the reagent preparation room 3. It is convenient for collecting samples outside the vehicle and transferring them to the specimen preparation room 4 through the specimen transfer window 18 for specimen preparation. A certain number of nucleic acid samples can also be brought into the specimen preparation room 4 through the first safety door 9.

[0039] In this embodiment, the reagent preparation room 3 is provided with a first buffer room 6 independent of the reagent preparation room 3, the first safety door 9 is used to enter and exit the first buffer room 6, and a second safety door 14 for entering and exiting the reagent preparation room 3 is provided on the side wall of the first buffer room 6. In this embodiment, the first buffer room 6 is added to the reagent preparation room 3, so that the medical staff and other personnel entering and exiting the reagent preparation room 3 can perform disinfection and sterilization in the first buffer room 6. The safety of the reagent preparation room 3 is improved.

One end of the first exhaust pipe 26 is connected to the first filter 25, and the other end of the first exhaust pipe 26 is connected to the first exhaust fan 40. The first exhaust fan 40 is used to filter the air in the reagent preparation room 3 through the first filter 25 and then discharge it. The independent air intake and exhaust are carried out by the independently arranged first fresh air system, which effectively ensures that the air in the reagent preparation room 3 is sterile and will not be cross-infected by other rooms, and ensures that the air supply and exhaust can be controlled separately, saving energy.

[0044] In this embodiment, the second fresh air system includes a second fresh air fan 31 and a second air inlet pipe 32. The second fresh air fan 31 is arranged at one end of the temperature-controlled ventilation equipment room 41 and is used to disinfect and sterilize the external air and input it into the specimen preparation room 4 through the second air inlet pipe 32. The second fresh air system also includes a second filter 27, a second exhaust pipe 28 and a second exhaust fan 39. One end of the second exhaust pipe 28 is connected to the second filter 27, and the other end of the second exhaust pipe 28 is connected to the second exhaust fan 39. The second exhaust fan 39 is used to filter the air in the specimen preparation room 4 through the second filter 27 and then discharge it. The independent air intake and exhaust of the independently arranged second fresh air system can effectively ensure that the air in the specimen preparation room 4 is sterile and will not be cross-infected by other rooms, and ensure that the air supply and exhaust can be controlled separately to save energy.

[0045] In this embodiment, the third fresh air system includes a third fresh air fan 30 and a third air inlet pipe 33. The third fresh air fan 30 is arranged at one end of the temperature control ventilation equipment room 41 and is used to disinfect and sterilize the external air and input it into the amplification analysis room 5 through the third air inlet pipe 33. The third fresh air system also includes a third filter 34, a third exhaust pipe 35 and a third exhaust fan 36. One end of the third exhaust pipe 35 is connected to the third filter 34, and the other end of the third exhaust pipe 35 is connected to the third exhaust fan 36. The third exhaust fan 36 is used to filter the air in the amplification analysis room 5 through the third filter 34 and then discharge it. The independent third fresh air system is used to independently supply and exhaust air, effectively ensuring that the air in the amplification analysis room 5 is sterile and will not be cross-infected by other rooms, and ensuring that the air supply and exhaust can be controlled separately to save energy.

[0046] In this embodiment, a second buffer room 7 independent of the specimen preparation room 4 is provided in the specimen preparation room 4, and the first fresh air system also includes a branch air intake pipe 29 connected to the first air intake pipe 24, a fourth filter 37 and a fourth exhaust pipe 38, the other end of the branch air intake pipe 29 is connected to the second buffer room 7, and the first fresh air fan 23 is used to disinfect and sterilize the external air and then input it into the second buffer room 7 through the first air intake pipe 24 and the branch air intake pipe 29; one end of the fourth exhaust pipe 38 is connected to the fourth filter 37, and the other end of the fourth exhaust pipe 38 is connected to the first exhaust fan 40, and the first exhaust fan 40 is used to filter the air in the second buffer room 7 through the fourth filter 37 and then discharge it.

[0047] The independent first fresh air system is used for independent air intake and exhaust, which effectively ensures that the air in the second buffer room 7 is sterile and will not be cross-infected by other rooms, and ensures that the air supply and exhaust can be controlled separately, saving energy.

[0048] Among them, the second buffer room 7 is smaller than other rooms, so from the perspective of energy saving, no separate fresh air system is set up. Its air intake is shared with the first fresh air system by a first fresh air fan 23, and a branch air intake pipe 29 is connected to the first air intake pipe 24 to meet the air intake of the second buffer room 7. Its exhaust is shared with the amplification analysis room 5 by a first exhaust fan 40. Because the second buffer room 7 is the passage in and out of the specimen preparation room 4, it needs to be specially ventilated and exhausted. Filter.

[0049] Preferably, a second filter 27 is provided at the outlet end of the second air inlet pipe 32. Since the specimen preparation room 4 is a preparation room required for configuring specimens, a higher level of air cleanliness is required in the laboratory. A second filter 27 can be provided at the outlet end of the second air inlet pipe 32 to further disinfect and sterilize the air entering the specimen preparation room 4.
