<p>A <a href="https://www.hondemedical.com/endotracheal-tube" rel="noopener noreferrer" target="_blank">endotracheal tube</a> is a medical device inserted into the trachea and/or bronchus of a patient to create a temporary artificial breathing channel for the patient, especially the patient who cannot breathe spontaneously.</p><p><br></p><p>The basic structure of the endotracheal tube</p><p>Common cannula heads have one or two cuffs. After the cuffs are inflated, they can fix the cannula and seal the airway, or without cuffs. The body of the intubation tube is usually made of polymer material, and a wire coil is embedded in the tube body to improve radial strength and axial flexibility. Part of the intubation tube body is made of anti-laser materials or multiple layers to resist laser irradiation. It is a cannula inserted into the patient's trachea through the nose/oral or percutaneous. One end is connected to an anesthesia ventilator through a breathing tube to maintain the patient's breathing. Provided aseptically, for single use.</p><p>1. The distal end of the catheter has a beveled opening.</p><p>2. A sleeve-shaped inflatable cuff is attached to the distal end.</p><p>3. There is an adapter tube connected to the respirator at the proximal end.</p><p>4. The cuff is connected by a thin tube and a small test balloon to understand the expansion and contraction of the cuff and its inflation pressure.</p><p>5. Murphy side hole is located on the far side wall of the distal cuff of the endotracheal tube. Its purpose is to change the breathing gas into and out through this side hole when the endotracheal tube obliquely sticks to the tracheal wall.</p>
