Abstract: The present invention relates to apparatus for measuring physiological parameters in a blood vessel. The apparatus comprises at least one acoustic sensor positionable on a part of a subject's body which is configured to receive an acoustic signal from a target blood vessel. The acoustic sensor is attached to the part of the subject's body by an attachment means.

Abstract: An enclosure for a wearable acoustic monitoring device, the enclosure comprising: a hollow body portion defined by a sidewall and top wall; and a substantially planar base portion configured to interface with the hollow body portion thus forming a chamber therebetween, wherein, the base portion comprises a flat engagement surface, for engagement with a body surface, and an acoustic port through the flat engagement surface for acoustic communication from the body surface to an acoustic sensor housed within the chamber, and, wherein, the acoustic port is located within a depression in or elongate channel through the flat engagement surface of the base portion such that the acoustic sensor is spaced apart from the body surface, in use.

Abstract: A method of identifying a breath comprises sensing a signal generated by a living human or animal body and separating the signal into a plurality of frequency bands to identify a breath candidate.
