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.

The invention refers to a device for collecting liquid from exhalation gas from a patient. The device includes a first pipe conduit (5, 8) for the supply of inhalation gas to the patient, a second pipe conduit (6, 9) for the removal of exhalation gas from the patient and a container device (1) for collecting liquid from the exhalation gas. The container device includes a first space (2), which forms a portion of the first pipe conduit (5, 8) and through which the inhalation gas thus flows, and a second space (3), which forms a portion of the second pipe conduit (6, 9) and through which the exhalation gas thus flows. The second space (3) is arranged to receive the collected liquid. The first space (2) is separated from the second space (3) by means of a wall member (4), which has a good thermal conductivity and permits transfer of heat from the exhalation gas to the inhalation gas.

A ventilation system for intensified breathing that includes both a manual ventilation system and automatic ventilation system. The gas mixture from a gas supply system is supplied to a switching valve that is operable between a manual position and an automatic position. When the switching valve is in the manual position, the inhalation gas from the supply system is guided to a manual ventilation bag. When the ventilation bag is squeezed during manual inhalation, the gas flow from the manual bag is directed to the inhalation limb of the patient circuit. When the manual ventilation bag is released, the pressure within the ventilation bag falls below the exhalation pressure, thereby indicating the beginning of the exhalation phase and the re-inflation of the manual ventilation.

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.
