3 results about "Tracheotomy" patented technology

This utility model relates to the field of tube-blocking devices, specifically a tube-blocking device for tracheotomy. It addresses the shortcomings of existing technologies by enabling progressive tube blockage of the tracheotomy cannula, facilitating recovery and successful extubation. The device includes an externally threaded tube, with an insertion component connected to one end for inserting the cannula, and a fixing plate connected to the other end. The top of the fixing plate has a groove communicating with the externally threaded tube, and two opposing stops for opening and closing the tube opening are slidably connected within the groove. A rotating ring is threaded onto the externally threaded tube, and the rotating ring has a rotating groove. The bottom of the fixing plate has two sliding holes corresponding to the stops. Two transmission components, passing through the sliding holes and connected to the stops, are slidably connected to the rotating groove. Rotating the rotating ring drives the transmission components to move the stops closer together or further apart on the groove.

This invention relates to the field of medical artificial intelligence technology and discloses an intelligent assessment and early warning system for extubation indications in tracheostomy patients. The system includes a disturbance response acquisition module, a state evolution trajectory construction module, a trajectory topology alignment module, an implicit knowledge transfer module, a counterfactual deduction module, and an extubation decision output module. By applying multi-band micro-airflow disturbances to detect airway dynamic stability, it constructs a patient state evolution trajectory, performs topological alignment with a historical case database, transfers implicit experience from similar cases, and uses counterfactual deduction to determine the optimal intervention timing and measures, generating extubation decision suggestions and risk warning information. This invention achieves a leap from passive observation to active detection, and from individual assessment to the transfer of collective wisdom, providing a precise and quantitative scientific basis for extubation decisions.
