Fume cupboard for biological medicine

Abstract

The invention discloses a fume cupboard for biological medicine, and relates to the technical field of biological medicine. The fume cupboard comprises a table, an L-shaped ventilation box is fixed tothe upper surface of the table, side plates are arranged between the two sides of the L-shaped ventilation box and the upper surface of the table, a transparent blocking window is fixed among the front end of the L-shaped ventilation box, the side plates and the table, the transparent blocking window comprises an oblique glass plate and a vertical glass plate which are arranged integrally, and the surface of the vertical glass plate is provided with hand inserting holes; and an air suction opening is fixed to the upper part of the front end of the L-shaped ventilation box, and an exhaust fanand an efficient particle filter are fixed inside the L-shaped ventilation box. According to the fume cupboard, through airtight design of the L-shaped ventilation box and the transparent blocking window, hands can pass through the hand inserting holes to conduct experiments under an airtight environment on the table for the experiments, so that harm of harmful gas is greatly reduced; and air circulation of inletting air from the bottom and exhausting the air from the top is formed through the air suction opening and an air hole plate, and the harmful gas is exhausted after filtered by the efficient particle filter, so that the harmful gas is effectively prevented from secondary entering.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, in particular to a fume hood for biomedicine. Background technique [0002] The main function of the fume hood is to control all kinds of harmful gases, water vapor, odor, waste heat, etc. generated during the experimental operation in the fume hood and discharge them to the outside, so as to protect the safety of users and prevent the pollutants in the experiment from flowing into the air. Purpose of laboratory diffusion. Fume hoods are widely used in various biochemical and physical and chemical laboratories. They play an important role in protecting the purity of experimental samples, ensuring the accuracy of experimental results, maintaining the cleanliness of the laboratory environment, improving labor hygiene conditions and improving work efficiency. Crucial role. [0003] There are still some deficiencies in the current fume hoods. The tuyere efficiency of many fume hoods is not high...

Problems solved by technology

[0003] There are still some deficiencies in the current fume hoods. The tuyere efficiency of many fume hoods is not high, and it is difficult to quickly absorb and discharge the gas. In addition, the discharged air will pollute the environment and cause harm if it is not treated. It is easy to enter the room for the second time, so there is still a big safety hazard
