Embedded trachea cannula plugging device

The utility model belongs to the technical field of medical instruments, and relates to an embedded trachea cannula plugging device which comprises a silica gel cannula plug, a silica gel outer cover is arranged in the middle of the cannula plug, the outer cover is designed to be of an umbrella-shaped structure, external threads are arranged on the lower portion of the cannula plug, and the bottom end of the cannula plug is designed to be of a conical structure. A central through hole is formed in the axial direction of the pipe plug, and a silica gel plug core is detachably arranged in the central through hole. The tube plugging device can effectively solve the problems that when a self-made plug is used for plugging a trachea cannula, the plug is not tightly attached to the trachea cannula, is prone to loosening and even falls off, and meanwhile the plug has the risk that the plug is sucked into the trachea cannula. Therefore, the medical safety is ensured, and the medical risk is reduced. 本实用新型属医疗器械技术领域，涉及
