Since the outbreak of the new crown pneumonia, various provinces and cities have normalized the prevention and control of the epidemic, and everyone is becoming more and more familiar with the term "nucleic acid testing". When it comes to nucleic acid detection, I have to mention the mobile nucleic acid detection workstation-PCR shelter laboratory.
Q1 What is a PCR laboratory?
The PCR laboratory, also known as the gene amplification laboratory, is a testing method specifically used to test viral infectious diseases such as AIDS, hepatitis B, and poultry disease. It can be used to amplify the genes contained in the virus to detect whether some infected persons with low virus content contain specific viruses. It is the main detection method for the new coronavirus.
The core issue in the design of clinical gene amplification testing laboratories (PCR laboratories) is how to avoid contamination. Therefore, the layout of the laboratory, the design of air conditioning and ventilation systems, and airflow control are all centered on this core issue.
Q2 What is a "mobile" PCR laboratory?
To put it simply, a square cabin is used to build a place that meets the standards for PCR laboratory construction, and the relevant equipment is placed in the square cabin to form a simple PCR laboratory that can be moved. Don't think of it as a simple laboratory, but the equipment in the shelter is not simple at all. It can be said that "the sparrow is small, but it has all the internal organs."
Q3 Why build a PCR shelter laboratory?
1. When an epidemic occurs, the mobile PCR shelter laboratory can be quickly transported to the place where the epidemic occurred to carry out testing.
2. The mobile PCR shelter laboratory was transported to the place where the epidemic occurred for centralized testing, reducing the mobility of patients, thereby blocking the path of virus transmission and controlling the epidemic.
3. When an epidemic occurs, a large number of PCR laboratories need to be built; after the epidemic, a large number of idle PCR laboratories cause huge waste, and mobile PCR laboratories are flexible and changeable, and one cabin has multiple uses.
4. The mobile PCR shelter laboratory can perform on-site testing after collecting samples, reducing sample circulation time and improving testing efficiency and accuracy.
Q4 What are the characteristics of the shelter PCR laboratory?
1. Small footprint
The storage area is about 30 square meters. It can be used as a vehicle-mounted laboratory in an emergency, and can be used for simple debugging when transported to the place where the epidemic occurs.
2. The installation requirements are not high
Single cabinet configuration, integration of water, electricity, wind, waste water and waste gas treatment systems. The site only needs to simply hoist and place the box, and connect the water supply and electricity, and the assembly is really fast.
3. Sustainable use
The mobile PCR laboratory can be reused. After the epidemic is over, it can be re-transported to the CDC, hospital, port or third-party testing unit after the epidemic is over after disinfection by professionals. It can also be professionally stored and maintained when needed. Putting it back into use is conducive to cost saving and resource reuse.
4. Fast pollution elimination
The cabinet is placed outdoors, and the outdoor air circulates quickly, which effectively avoids aggregation and infectivity; when the internal environment of the laboratory is polluted, fresh air can be quickly replaced by the air supply and exhaust system to meet the requirements of laboratory purification.
