摘要

An arrangement for protecting the breathing passages of laryngectomees comprises a flexible, apertured mounting element (1) adapted to be sealingly applied to the throat of the laryngectomee and connected to a projecting socket-shaped holder (3) accommodating an exchangeable filter means (5) through which the air passes during inhalation and exhalation through a throat stoma (2). The holder is adapted to contain the filter means substantially within a space defined by the holder wall, and has means ensuring that the filter means is held in place and preventing it from being ejected from the holder.
