20080216839Tracheostomy Tube - An improved tracheostomy tube providing a decreased tendency to produce rubbing, pressure necrosis, ulceration and scarring of the tracheal mucosa. The tube typically includes a rigid proximal section, a flexible intermediate section, a rigid distal section, and a beveled distal tip. The flexible intermediate section has a smooth surface and bends easily in response to pressure asserted by the tracheal walls, allowing the distal rigid section of the tube to remain in a parallel orientation relative to the tracheal lumen, The distal tip of the tube is beveled to provide a greater cross-sectional area at the tube's distal section. This beveled distal tip prevents the distal section of the tube from becoming obstructed by the back wall of the trachea or causing erosion of the tracheal mucosa. The distal tip also has a beaded or rounded edge, which further minimizes the risk of damage to the tracheal mucosa and provides a guide to the clinical care specialist during suctioning.09-11-2008
