A branching unit for delivering a respiratory gas of a subject is disclosed herein. The branching unit includes a first limb for delivering an expiratory gas during an expiratory phase and a second limb for delivering an inspiratory gas during an inspiratory phase. The branching unit also includes a third limb for delivering both the expiratory gas and the inspiratory gas and a common branching point for the first limb, the second limb and the third limb. The first limb, the second limb and the third limb include a volume for the respiratory gas and which volume includes both an active volume with the gas exchanging between the inspiratory phase and the expiratory phase and a dead volume for the respiratory gas with insufficient gas exchange from the inspiratory phase to the expiratory phase and the dead volume being less than 1 ml.

A nebulizer determines the pressure and flow direction of the receiving gas for atomized liquid. A member of the apparatus is subjected to pressure exerted by the gas. The member is coupled to a bi-directional mechanical-electrical conversion element, such as a piezoelectric element, to form a pressure transducer. The member exerts a mechanical loading on the element responsive to the gas pressure to which it is subjected. In one embodiment, the element mechanically vibrates responsive to alternating electrical energization to discharge the liquid into the gas. The electrical admittance of the element is alterable by the mechanical loading applied to the element by the member. The difference between admittances measured in the loaded condition of the element and in an unloaded condition at the selected energization frequency is an indication of the pressure of the gas. By observing whether the magnitude of the admittance in the loaded state is greater or less than that in the unloaded state, the flow direction of the gas may also be determined. Or the flow direction may be determined by observing the changes in admittance as the frequency of the electrical energization is varied. In another embodiment, the piezoelectric element is not energized. The electrical output of the element, when subjected to a mechanical loading from the gas pressure, is used to detect gas pressures and/or as an indication of the gas pressure.

A sensor for measuring a respiration is disclosed herein. The sensor includes at least one housing (7) having a first cavity (12) with a first port (11) allowing a respiration gas flow, and a second cavity (22) with a second port (21) also allowing a respiration gas flow. The sensor also includes at least one breathing detector (51) for acquiring a signal indicative of the respiration gas flowing through the first cavity and the second cavity. The at least one housing is equipped with at least one additional port (31) for removing the respiration gas flow coming from the first cavity and the second cavity, which additional port being separate from the first port and the second port.

The invention relates to paramagnetic gas analyzer with a housing, comprising: an electromagnet with an air gap; power source for said electromagnet; a sample gas conduit and a reference gas conduit into said air gap; an exit conduit communicating with said air gap for removing the intermixed gases; pressure detecting microphones connected to said sample gas conduit and to said reference gas conduit for sensing the gas pressures; as well as electronics. The pressure detecting microphones comprise two independent microphonic membranes that are parallel to each other, their pressure surfaces being to the same direction, or to the opposite directions. The electrical outputs of the microphones provide signals that are proportional to gas pressures in the sample gas and reference gas conduits, and that are further processed in the electronics to eliminate effects of mechanical shocks or the like.

A non-dispersive single beam detection assembly in an infrared gas analyzer. The detection assembly comprises radiation source(s) providing infrared radiation, a measuring chamber, and a physical beam splitter for dividing said radiation beam into a reflected beam portion and a transmitted beam portion, or for combining a reflected beam portion and a transmitted beam portion into said radiation beam. A measuring detector receives one beam portions, and a reference detector receives another beam portion. Alternatively a measuring/reference detector receives both beam portions. Said transmitted beam portion has a first spectral intensity peak at shorter wavelengths with a first peak wavelength, and said reflected beam portion has a second spectral intensity peak at longer wavelengths with a second peak wavelength. There is a wavelength gap between said second peak wavelength and said first peak wavelength, which gap corresponds a wavelength shift of an optical interference filter with said second peak wavelength as tilted from its perpendicular position to an angled position. Said wavelength gap is at maximum 10% of the second peak wavelength, and at minimum 0.5% of the second peak wavelength.
