Film-flipping mechanism for molecular testing, nucleic acid extraction device with the same, and nucleic acid extraction method for molecular testing

Abstract

A nucleic acid extraction device for molecular testing comprises a film-flipping mechanism, a cap mechanism, a dispensing mechanism, an extraction plate transfer mechanism, and a nucleic acid extraction module. A sealing film is adhered onto top of an extraction plate and folded along an outer edge of the extraction plate. A film-flipping head of the film-flipping mechanism abuts against a bottom surface of the extraction plate and pushes an edge of the sealing film to unfold the sealing film. A film gripper clamps and removes the unfolded sealing film. The cap mechanism opens the specimen containers. The dispensing mechanism transfers the specimens from the specimen containers to the extraction plate. The extraction plate transfer mechanism moves the extraction plate with the specimens to the nucleic acid extraction module. As a result, molecular testing is automated to reduce labor and improve quality.
