Combined type biologic safety operating chamber

Abstract

The invention relates to a cleaning device used for a laboratory, and in particular relates to a combined type biologic safety operating chamber. The operating chamber comprises an upper sealing box and a working area, wherein the upper sealing box is positioned above the working area; walls are respectively arranged at the rear side, left side and right side of the working area; the upper sealing box is formed by combining and hermetically connecting metal shells; a door is arranged in front of the working area; the door comprises an operating window and a door body; the walls and the door body are formed by combining and fixedly connecting hollow modules; each hollow module comprises an inner plate and an outer plate; the inner plate and the outer plate are fixedly connected; a hollow cavity is formed between the inner plate and the outer plate; an air port is arranged on the side edge of each hollow module; the hollow cavities between adjacent hollow modules are communicated with each other through the air ports; the hollow cavities are negative pressure cavities; the working area is encircled by the negative pressure cavities; and an operating table type trolley is arranged in the working area. The combined type biologic safety operating chamber can supply a local clean environment to a large-scale experimental device. The combined type biologic safety operating chamber has convenience in mounting, can be mounted on site, and is convenient for an experimenter to perform an experiment.

Description

technical field [0001] The invention relates to a laboratory clean equipment, in particular to a combined biological safety operation room. Background technique [0002] When operating experimental equipment in biological experiments, a large amount of aerosol may be generated during the operation. The aerosol floating in the environment will pollute the surrounding experimental environment and cause harm to the human body, and the tiny particles in the environment will also pollute the experimental samples. [0003] In order to avoid the occurrence of the above situation, common biological experiments are generally carried out in biological safety cabinets. Biological safety cabinets are laboratory clean equipment equipped with high-efficiency air filters. Biological safety cabinets are generally used for analysis and research of laboratory microorganisms. Among them, the secondary biological safety cabinet is a sealed device with a front opening. Laboratory operators c...

Problems solved by technology

[0004] Existing biological safety cabinets are generally only suitable for the operation of containers, but some large-scale experimental equipment such as flow cytometers, high-speed centrifuges, and aerosol generators cannot be placed in biological safety cabinets; The safety cabinet is an integrated structure with limited carrying capacity. In view of the space of the laboratory, it is impossible to manufacture a large biological safety cabinet to hold large experimental equipment such as flow cytometers and high-speed centrifuges.
