Abstract: Embodiments are described for treating a fluid, e.g., a biological fluid. The embodiments may include systems, apparatuses, and methods. Embodiments may provide for a flow cell, with a plurality of manipulation elements, through which a fluid is flowed. The fluid may be treated (e.g., exposed to energy) as it moves through the flow cell. In embodiments, the flow cell may be used to inactivate pathogens in the fluid.

Abstract: Respiration monitoring equipment comprises, in one embodiment, a medical face mask (2), adapted to be located adjacent, or to cover a patient's nostrils and/or mouth; a transducer (7) adapted to be impinged by the patient's inspired and/or expired breaths, being sensitive to the presence and/or absence of a respiratory air flow, and being capable of emitting electrical signals in accordance with the presence and/or absence of a respiratory air flow; and a monitoring unit (9) electrically connected to the transducer (7) and responsive to the presence and/or absence of signals emitted by the transducer (7), and including means of triggering at least an alarm signal in the circumstances of non-detection of respiratory air flow within one or more predetermined parameters. Another embodiment provides for “cordless” monitoring, with a transmitter unit (11) at the face mask (2) and a receiver (12) at the monitoring unit (9).
