Abstract: The present invention relates to a liquid atomizer device for producing aerosols. The device includes a first housing part (A) which includes an inner member (3) of an atomizer nozzle and a first connection for connecting the first housing part (A) to a further housing part to form a nebulizing chamber (1), and further includes a second housing part (B) that includes an outer member of the atomizer nozzle which can be brought into engagement with the inner member (3) to form the atomizer nozzle, and a second connection means (11) that can be brought into engagement with the first connection (9) for connecting the second housing part to the first housing part. The invention is characterized in that a service life indicator (L) is arranged at a place that does not impede the flow passing through the device, but is accessible to the aerosol and a sterilant.

Abstract: The present invention refers to a compressor head according to German Patent 199 27 458.4, wherein the valve elements are multiple-beak valves, the slot-shaped valve openings of which are arranged at right angles to each other.

Abstract: In oxygen therapy, the patient is provided a mixture of air and oxygen. In the process, the oxygen is led from an oxygen supply container or an oxygen concentrator through a tube to the patient and made available for inhalation. The distribution system includes a whirler with openings directed toward the patient's mouth and nose. The oxygen flow is twisted into a spiral shape inside the whirler before it exits from the openings.
