Device for rapidly extracting DNA (deoxyribonucleic acid) from cast-off cells

Abstract

The utility model relates to the field of DNA extraction, and discloses a rapid extraction device for exfoliated cell DNA, which comprises an extraction instrument main body, a cabin door is hinged to the outer wall of the extraction instrument main body, a control console is arranged on the outer wall of the extraction instrument main body, a sliding rail is fixedly connected to the inner wall of the extraction instrument main body, and a base is slidably connected to the inner wall of the sliding rail. A threaded rod is rotatably connected to the inner wall of the base, a rotary knob is fixedly connected to the tail end of the outer side of the threaded rod, two sets of threaded sleeves are connected to the outer wall of the threaded rod in a threaded mode, a fixing assembly is hinged to the outer walls of the threaded sleeves and comprises a support, and the end, close to the inner side, of the support is hinged to the outer walls of the threaded sleeves. A clamping plate is hinged to the other end of the support, a telescopic rod is arranged on the inner wall of the extraction instrument body, and an extraction mechanism is detachably connected to the bottom end of the telescopic rod. According to the clamping base fixing device, clamping bases of different specifications can be fixed, and the extraction efficiency is improved.
