Abstract: A negative pressure respiratory treatment hood for human medical patients. A rigid hood, preferably of unitary fabrication from a clear material, is positioned over the patient's head. The patient's body extends out of an opening in a front wall of the hood. A hinged door may be attached to the front wall of the hood, and is closed and partially closes the opening, and a shroud is sealing connected to the hood and is draped over the patient so as to form a pressure seal. A negative pressure source is connected to the hood and forms a negative pressure environment around the patient's head. Access openings have a resilient material across them, with small openings in the resilient material, to permit access to the patient by medical personnel and/or medical equipment.

Abstract: A surgical/medical tube such as an endotracheal tube (10) is provided having a tubular body (12) equipped with an inflatable cuff (22) and respective, separate cuff inflation and fluid removal lumens (24, 30). A fluid removal opening (32) communicates with lumen (30) and is located proximal to cuff (22). A projection (38, 38a, 40, or 42) is located in close proximity to the opening (32) and is configured to prevent contact between the opening (32) and the adjacent tracheal wall.

Abstract: A medical device tube comprising a cannula having a formed end and a connector that tightly holds the formed end of the cannula between first and second portions of the connector.

Abstract: A laryngeal airway device, having an airway tube which has an internal passage in the airway tube wall for receiving a cuff inflation line, and a dome having an inlet and an outlet, where the dome is connected at its inlet with the distal end of the airway tube. The device also includes an annular spoon-shaped inflatable cuff connected with the periphery of the outlet of the dome; a cuff inflation line configured to be in fluid communication with the internal space of the cuff; and a multi-lobed aperture formed in the dome. The aperture is configured to be in fluid communication with the proximal end of the airway tube. The dome has protrusions forming the multi-lobed aperture, such that a flap is configured to prevent the obstruction of the aperture by a patient's epiglottis when the device is inserted into the patient.

Abstract: A method is provided for exercising an engine-driven, electrical generator. The generator has a first operation mode wherein the generator generates a predetermined output voltage at a predetermined frequency with the engine running a predetermined operating speed and a second exercise mode. The method includes the step of running the engine at a predetermined exercise speed with the generator in the exercise mode. The predetermined exercise speed is in the range of 40% to 70% of the predetermined operating speed of the engine. In addition, in the exercise mode, the generator generates an exercise voltage that is less than the predetermined output voltage.
