The invention relates to a hemostatic membrane storage device comprising a box and a tray which can vertically slide in the box. A vertically-arranged air cylinder arranged above the tray is arrangedin the box; the air cylinder is internally provided with a first piston, a second piston and a push rod, wherein the second piston and the push rod are arranged above the first piston; the lower end of the push rod is connected with the first piston, and the push rod is slidably connected with the second piston; and the upper end of the push rod is arranged on the upper portion of the box. A limiting sliding groove is formed in the air cylinder; a tension spring arranged above the second piston is arranged in the air cylinder; the two ends of the tension spring are connected with the air cylinder and the second piston correspondingly; a flange which is arranged in the air cylinder and arranged above the second piston is arranged on the push rod; a suction cup arranged on the left side of the air cylinder and provided with a downward opening is arranged on the air cylinder; the upper end of the suction cup is rotatably connected with the air cylinder, and the inner side of the suction cup and the inner side of the air cylinder always keep communicating; and a vertically-arranged threaded rod which is arranged below the tray and a nut connected with the threaded rod through a threadare arranged in the box, the upper end of the threaded rod is connected with the tray, and the nut is rotatably mounted on the box.
