<p>An apparatus (10) for monitoring respiratory movements of a person, having a lower surface member (11) and an upper surface member (12) adapted to move relative to the lower surface member (11). The upper surface member (11) is provided with at least one protrusion (18) extending downwardly therefrom which is adapted to directly or indirectly contact a piezo-electric transducer device or the like device (15), the other end of the piezo-electric device (15) being connected, also directly or indirectly, to the lower surface member (11). Preferably, each protrusion (18) contacts the piezo-electric device (15) via a flexible arm (16), for increase insensitivity of the apparatus. By sensing wether movement of the upper surface member (12) occurs an electrical signal is generated by the piezo-electric device (15) which operates an alarm in the event that respiratory movement is not sensed.</p> |
