Description

Technical Field

[0001] The invention relates to the field of biosafety protection technology and equipment, and in particular to a negative pressure dissection sampling table for infectious medium-sized animals. Background Art

[0002] Laboratory animals are indispensable experimental materials in life science research and play an important role in the human fight against pathogenic microorganisms. In the process of experimental research, the dissection of infectious animals has a high biosafety risk.

[0003] At present, the dissection of infectious small animals is usually performed in a biosafety cabinet, such as rodents, rabbits, poultry, etc., which are small in size and can be operated more conveniently in a safety cabinet, while effectively ensuring the safety of the operator and the surrounding environment. For infectious medium-sized animals, such as monkeys, dogs, piglets, etc., they are larger in size and require two people to cooperate in bilateral operations, and the existing biosafety cabinets are difficult to meet the requirements of operating space; if the dissection is performed directly in an open environment, it will cause serious pollution to the environment, and at the same time, higher requirements are placed on the individual protection level of the operator and the protection level of the space. However, at present, there is no isolation operation equipment suitable for negative pressure dissection of infectious medium-sized animals on the market. In order to overcome the above shortcomings, it is urgent to develop isolation equipment that can meet the needs of dissecting and sampling of infectious medium-sized animals to improve operational convenience and biosafety. Summary of the invention

[0004] In view of the problem that existing biosafety cabinets are difficult to meet the space requirements and protection requirements for negative pressure dissection of infectious medium-sized animals, the present invention discloses a negative pressure dissection table for infectious medium-sized animals, which can be used for dissection of infectious medium-sized animals and is an isolation device with high biosafety protection performance.

[0006] The negative pressure dissection sampling table for infectious medium-sized animals is provided with working windows on both sides of the box body, and the working windows on both sides of the box body can be opened at the same time.

[0007] The exhaust high-efficiency filtering device is arranged on the upper part of the lifting glass and is tightly connected to the lifting glass in an airtight manner; the lifting glass is arranged on the upper part of the working table and working window of the box and is tightly connected to the working table and working window of the box in an airtight manner, and the area between the exhaust high-efficiency filtering device, the lifting glass and the box constitutes a closed space.

[0008] The exhaust high-efficiency filtering device includes a filtering box, a high-efficiency air filter, a scanning sampling probe, a sampling tube, a sampling interface and a scanning drive mechanism. The high-efficiency air filter is installed at the front end of the filtering box and is used to filter the biological aerosols generated during animal dissection.

[0009] An exhaust fan and a fan frequency converter are arranged on the top of the pipeline of the exhaust high-efficiency filter device of the negative pressure dissection sampling table for infectious medium-sized animals. The exhaust fan is connected to the fan frequency converter. Under the suction action of the exhaust fan, external air flows into the interior of the dissection sampling table from the working window to form a directional airflow from the outside to the inside. The directional airflow is filtered by the exhaust high-efficiency filter device and then discharged to the outside of the dissection sampling table.

[0010] A wind speed sensor is provided on one side of the upper part of the work surface. The wind speed sensor detects in real time the velocity of the rising vertical airflow in the closed space formed by the exhaust high-efficiency filter device, the lifting glass and the box body. The fan inverter is used to adjust the fan frequency of the exhaust fan according to the flow velocity collected by the wind speed sensor, thereby changing the suction air volume of the exhaust fan to ensure that the airflow velocity flowing into the working window reaches the standard value, forming a directional airflow from the outside to the inside, and ensuring that bioaerosols do not leak to the outside of the dissection table during the dissection work, thereby protecting the safety of the operator and the environment.
