    摘要： A diaphragm device for a check valves is provided. The diaphragm device comprises a diaphragm, adapted to cover at least one orifice, and an operation device, adapted to enable movement of the diaphragm substantially along a length axis of the orifice. The operation device comprises at least one first operation organ and at least one second operation organ. The first and second operation organ in turn each comprises a first portion, and a second portion. The first portion of the first operation organ is adapted to be connected to a check valve housing, and the second portion of the first operation organ is connected to the second portion of the second operation organ. Furthermore the first portion of the second operation organ is connected to the diaphragm and the second portion of the second operation organ is connected to the second portion of the first operation organ. The first operation organ is movable in relation to the second operation organ, and the second operation organ is movable in relation to the diaphragm, for enabling movement of the diaphragm, substantially along the length axis of the orifice. This embodiment could enable the check valve to open a relatively long way by means of a relatively low pressure or flow, at the same time as the deformation of the resilient material could be relatively small since it is deformed in a multiplicity of points and along a relatively long extension of resilient material.

    摘要： Method for diagnosis of inflammatory conditions in the intestinal canal of humans, characterized in that NO is measured in the lumen of the intestines. The NO level obtained is then compared with the level obtained for healthy individuals or with the level obtained for the same individual at another occasion. An increased level compared to the normal levels in the intestines of the healthy population is an indication of an inflammatory condition in the intestine.

    摘要： A device for determining the level of nitric oxide in an exhaled airstream belonging to a living organism selected to have its lung function evaluated, where an initial device is arranged to determine the current portion of nitric oxide and/or the distribution of nitric oxide over time during an exhalation phase. During the commencing period of the exhalation phase, the exhaled air is arranged to pass with no or with only a very small resistance or back-pressure to a free space, and during the remaining period, the exhaled air is arranged to pass through the initial device against the action of a suitable resistance or back-pressure. The level of nitric oxide is measured during this remaining period.
