Abstract: The invention relates to a measurement device for the blood flow of an individual, for example for the detection of bubbles. The device comprises an acoustic emitter and a case with an emission surface capping the acoustic emitter. The emission surface is terminated at one end by a clavicular contact portion perpendicular to the emission surface and suited for coming to rest against a clavicle bone of the individual and is terminated at another end by a shoulder contact portion perpendicular to the emission surface and suited for coming to rest against a bone of the shoulder of the individual. A vertical distance between the middle of an active zone of the emission surface and the clavicular contact portion is less than 20 mm. A transverse distance between the middle of the active zone and the shoulder contact portion is included between 20 and 50 mm.

Abstract: A safety device for underwater diving has a sensor for measuring a flow of gas bubbles comprising a belt for fixing and functional coupling to the body of a diver. The flow sensor is linked to a portable computer for utilizing signals from the flow sensor so as to provide an alarm signal if the measured flow level exceeds a predetermined safety threshold and to thus customize a table of decompression stops.
