<p>A laryngoscope (10), has a blade (12) and a hollow body including a handle (11) and a cap (30) (see Fig. 2). The handle receives dry cells through an open end, closed by the cap (30). A sealed window (60) (Fig. 8) carried by the cap passes light from a light source (25) within the body to a predetermined zone at the cap exterior, whereby such light may be transmitted along the blade (12) removably attached to the cap. A flexible barrier (29) is carried by the cap (30) to be deflected by the blade (12) upon its attachment to the cap (30), the barrier (29) sealing off between the cap interior and exterior. Circuitry including a motion transmitting element (33) to be deflected within the hollow body in response to barrier (29) deflection to establish an ON condition of the circuitry for transmitting current from the dry cells (37) to the light source.</p> |
