Abstract: Disclosed is an occluding stent. The occluding stent includes a distal flange occluding body, a proximal flange occluding body, and a connection portion. External surfaces of the distal flange occluding body and the proximal flange occluding body are both provided with a coating. An external surface of the connection portion is wholly or partially provided with a coating. A first occluding coating is provided between the distal flange occluding body and an inner cavity of the connection portion. The present application overcomes the defect that the existing occluder device for closure of an esophagobronchial fistula is harmful to surrounding tissues, makes the device retractable, enhances the safety of the device, and improves life and treatment of patients. A new safe and effective treatment method for an esophagobronchial fistula is provided.

Abstract: Disclosed is an electric stirring cup, where one end of a hollow cup body is connected with a cup cover through threaded connection; one end of the hollow cup body far from the cup cover is connected with a base; a connecting end is integrally formed on the base; an inner wall of the one end of the hollow cup body far from the cup cover forms a connecting cavity, the connecting cavity is in threaded connection with the connecting end; a stirring mechanism is installed in the base; and a drinking mechanism is installed on the cup cover. A drink that needs to be stirred is poured in, and after being directly stirred and mixed through the stirring mechanism, the drink may be consumed after the cup cover is unscrewed, whereby the electric stirring cup is easy to use. The hollow cup cavity and the stirring mechanism may be directly cleaned after disassembling the base, whereby the electric stirring cup is easy to clean.

Abstract: A novel crash-resistant aircraft includes a fuselage and an aircraft base connected together via a movable fastener, and said fuselage comprises a cockpit, a cabin and an empennage. The aircraft base comprises a bellyhold cargo bay, a fuel tank, an undercarriage, a power unit and wings. The empennage is also connected to the tail end of said fuselage via a movable fastener. A crash-resistant propeller system capable of bringing said fuselage upward is set up at the top of said cabin, a crash-resistant recoil devices set up beneath said cabin. The crash-resistant aircraft also comprises a control system disposed in said cockpit, and when said aircraft is in an accident in midair, said control system releases said movable fastener to abandon said aircraft base and said empennage. Also disclosed is a crash-resistant operation method of the crash-resistant aircraft.
