Anti-contamination sample storage device for clinical laboratory

The invention provides an anti-contamination sample storage device for a clinical laboratory, and relates to the technical field of sample storage devices. The anti-contamination sample storage devicebased on the clinical laboratory comprises a base and an outer box body, the upper portion of the base is fixedly connected with the outer box body, one side of the upper portion of the outer box body is rotationally connected with an outer box cover through two hinges, an inner box cover is arranged in the middle of the outer box cover, a lifting handle is rotationally connected to the two sidesof the middle of the upper portion of the outer box cover, and a liquid crystal panel is arranged in the middle of the side, away from the hinges, of the upper portion of the outer box body. An air filter and an electric air pump are arranged and cooperate with an air pressure sensor and the inner box cover to achieve the sealing effect on an inner box body, the interior of the inner box body canbe pressurized and sealed, the interior of the inner box body is kept in a positive pressure state all the time, even if the sealing failure condition occurs, outside air can be prevented from entering the inner box body, contamination of the outside environment to samples is avoided, and novelty of the device is improved.
