Abstract:
1. An earplug comprising: a distal end; an inflatable element coupled to the distal end; and a flexible anti-distal end coupled to the distal end, the inflatable element operatively attached to the anti-distal end by an inflation channel, where the anti-distal end includes a stop flange, a bladder serving as a reservoir and a pinchable resilient member, the bladder being disposed between the stop flange and the pinchable resilient member, the bladder coupled to the inflation channel, the pinchable resilient member expands the inflatable element to an adjustable pressure by having the pinchable resilient member providing a pressurizing force to maintain the expansion of the inflatable element and where the reservoir expands by moving fluid from the inflation element to the reservoir when pinching the pinchable resilient member.
