<p>The device has a portable computer (1) receiving and exploiting signals from a gas bubble flow measuring sensor e.g. Doppler sensor (2), via a connector (3), where the computer is provided with a wireless connection emitter-receiver circuit (19) e.g. radio emitter-receiver circuit. A functional fixation and coupling strap (2A) is fixed and coupled to a body of a diver i.e. underwater working diver using a hypobaric case. The computer provides an alarm signal through a display (9) if a measured gas bubble flow level exceeds a predetermined safety threshold.</p> |
