TRACHEAL CANNULA AND SPEAKING-RESPIRATION SYSTEM FOR MECHANICAL RESPIRATION

摘要

The present invention relates to a novel tracheal cannula, which allows patients to speak who receive artificial respiration with compressed-air. The tracheal cannula according to the invention makes this possible without the risk that saliva or stomach content is aspirated and without the occurrence of a loss of pressure during the respiration. This is achieved by an embodiment of the cannula having a separated speaking conduit and respiration conduit. Furthermore, the invention relates to a speaking respiration system that can be connected to the tracheal cannula of the present invention, and that when used in a patient monitors and controls the respiration of the patient, and simulates an artificial exhalation that enables the tracheostomized patient to speak.
