An apparatus and method to characterize NO gas exchange dynamics in human lungs comprising the steps of: (1) performing a series of breath hold maneuvers of progressively increasingly breath hold times, each breath hold maneuver comprising a) inhaling a gas, b) holding a breath for a selected time duration, and c) exhaling at a flow rate which is uncontrolled but which is effective to ensure evacuation of the airway space and (2) measuring airway NO parameters during consecutive breath hold maneuvers. As a result disease states of the lungs are diagnosed using the measured airway NO parameters.

A device for a respirator. A tube is operative to be introduced into a trachea of a patient and supply and discharge gas from the patient's lungs. A first conduit connects the tube to the respirator to discharge exhalation gas. A second conduit extends between the tube and a source of sub-pressure. The second conduit is connected to an exhalation tube of the tube. A third conduit connects the tube to the respirator and supplies inhalation gas. In an active position a valve arrangement keeps the second conduit open and connects the exhalation tube to a source of sub-pressure. In an inactive position the valve arrangement keeps the second conduit closed and the first conduit open. A controller moves the valve arrangement from the inactive position to the active position for a period of time to simulate coughing to cause a gas flow to support transport of secretions.

A face mask for use in gas delivery applications, such as breathable gas or aerosol drug systems. The face mask includes a body having a peripheral edge for placement against the face of a wearer. The peripheral edge defines a single chamber over the nose and the mouth of the wearer. An inlet opening is formed on a surface of the body for supplying inhalation gas to the nose through the chamber. A vent assembly inwardly extends from the surface of the body to the chamber and seals around the mouth for passing exhalation gas to the exterior of the body.

The invention relates to a film component extraction apparatus, which can separate the film components which is difficult to separate and forms incisions one by one to extract. The film component extraction apparatus (FT) has: a plurality of attraction portions (98), which is supported on the topside of the film component (8), can be contacted and separated, and forms an adsorption port (98a) on the front end, wherein the film component (8) is loaded in the housing portion (26), for form a plurality of incisions; a dividing direction mobile component (92), which enables each attraction portion (98) to move in the separated antisymmetric direction of the film component (8); and a contact separation direction mobile component (82), which enables the attraction portion to move in the contact separation direction relative to the loaded film component, attracts the film component loaded on uppermost surface on the attraction portion by inhaling gas, and enables the attraction portion to separate from the housing portion (26) to process extraction at a status that these attraction portions are closed to one another.

Provided is a negative-pressure wound therapy apparatus capable of causing negative pressure in a closed space defined by a wound dressing and a wound region with a sufficient suction flow rate as needed even with a miniaturized pump device. In atypical use that needs a high suction flow rate, because a pump device (30) with a high suction flow rate is attached to a wound dressing (10) and sucks gas from a closed space (904) defined by a wound region (903) and the wound dressing (10), even when a pump device (20) for typical use is miniaturized and the suction flow rate of the pump device (20) is reduced, a therapy apparatus (100) can achieve a suction flow rate sufficient for atypical use. Thus, the pressure value in the closed space (904) can decrease to a desired value more quickly.
