Abstract: Various embodiments are directed to flow sensors and methods of using the same. In various embodiments, a flow sensor for measuring fluid flow within a breathing system may comprise a housing defining a flow channel and comprising: a housing body and a plurality of coupling members, wherein each coupling member defines an opening through the housing body, the plurality of coupling members comprising: a set of coupling members configured for coupling to a suction tube assembly, each of which is fluidly connected with the housing body via one of a plurality of bottom openings provided on a bottom side of the housing body such that the flow sensor facilitates a contaminant extraction operation defined by a contaminant present within the housing being extracted to the suction tube assembly through the coupling members; wherein each of the coupling members is integrally configured as part of the housing.

Abstract: The invention relates to a device and a method for measuring blood, tissue, or skin parameters, in particular the oxygen saturation in blood, by attaching one or more sensors to body parts such as fingers, earlobes, toes, hand, or foot. The invention relates further to a method for the preparation of said device.
