摘要： The present invention provides a medical device such as an endotracheal tube or a tracheostomy tube having a distal inflation cuff and a high surface area structure disposed radially around the tube on a proximal side of the cuff. The high surface area structure includes an antimicrobial agent. The relatively higher surface area of the structure and radial extension thereof from the tube allows the antimicrobial agent to better extend into a secretion pool collected in the region around the intersection of the cuff and tube within a patient's trachea, so as to better prevent biofilms from forming and thereby prevent infections such as ventilator assisted pneumonia (VAP).

摘要： A respiratory breathing circuit prevents heat loss and condensation in a flow of humidified air through a conduit from a humidification system to a patient interface, such as a nasal cannula. The circuit directly impedes heat loss or insulates the flow of a humidified gas therein, and provides a heating source inside the circuit along the length of the circuit to prevent net heat loss from the circuit tubing by providing thermal energy and/or insulation to impede convective, conductive, or radiative heat loss by the gas as it flows through the system. A temperature, humidity, or other flow quality measuring probe is disposed at the distal end of the circuit near the patient interface to actively measure a corresponding quality of the humidified gas flow to provide feedback to the system. A pressure relief valve is provided on the circuit to prevent a pressure build-up and/or structural failure.
