Abstract: An exhalation valve arrangement (22) for a ventilation apparatus for artificial ventilation of patients is flow-capable in an exhalation flow direction (E) and encompasses: an upstream respiratory gas conduit (54) that extends along a first conduit path (K1) and is connected or connectable to a portion, coming from the patient, of the exhalation line; a downstream respiratory gas conduit (58) that extends along a second conduit path (K2) and is connected or connectable to a respiratory gas sink (U); a valve subassembly (63) which comprises a valve body (64) and a valve seat (66) and which is provided between the upstream and the downstream respiratory gas conduit (54, 58) in such a way that, in the context of a predetermined first respiratory gas overpressure in the upstream respiratory gas conduit (54) relative to the downstream respiratory gas conduit (58), it permits an expiratory respiratory gas flow from the upstream respiratory gas conduit (54) into the downstream respiratory gas conduit (58); and in

Abstract: A measurement cuvette for detecting at least one fluid constituent of a fluid flowing through the measurement cuvette by means of electromagnetic radiation, includes: a channel, which extends through the measurement cuvette along a channel path extending centrally through the channel; a coupling and detection portion, which extends, between its first longitudinal end and its second longitudinal end, along a linear longitudinal axis, detachably mechanically coupled to a radiation component; a physical orientation structure, which allows detachable mechanical coupling of the measurement cuvette to the radiation component in a predefined desired relative orientation and prevents the detachable mechanical coupling in an undesired relative orientation. The physical orientation structure is arranged and formed between the first and the second longitudinal ends of the coupling and detection portion.

Abstract: The invention relates to a measurement device for determining at least one gas component of a gas present in a measuring chamber of the measuring device, the measuring device comprising a housing enclosing the measuring chamber, at least one housing wall section of which housing being designed as an observation section for detecting electromagnetic radiation emanating from the observation section in a direction away from the measuring chamber, the observation section comprising at least one film layer, and the housing being designed as a plastic injection-moulded housing. The invention is characterised in that the observation section has at least one observation wall component comprising an injection-moulded observation body injection-moulded onto the at least one film layer, and the housing comprises the at least one observation wall component and an injection-moulded frame body injection-moulded onto the observation wall component.

Abstract: An expiratory valve (10) of a ventilation device (100), including a valve body (12) having a fluid inlet (14) and a fluid outlet (16) for breathing air of a patient formed therein the valve body (12) defining a fluid flow path between fluid inlet (14) and fluid outlet (16), with the cross-sectional area of the fluid flow path expanding in the direction towards the fluid outlet (16).
