The present invention makes tracheostomy a safer modality of care with four distinctive features in the configuration. The four distinctive features are (1) a precision cuff fitted to each trachea; (2) a flexible tube that will conform to any depth of the trachea within the neck; (3) a self-locking clip that adjusts the tube securely to any neck regardless of the depth of the trachea; and (4) a malleable but rigid obturator for ease of insertion. These four features comprise the structure of the improved tracheostomy tube, being (1) a flexible tube, (2) an encircling pressure cuff, (3) a removably insertable malleable obturator, and (4) a self-locking neck plate to secure the tube to the neck. | |
