Abstract
A breathing protector for a laryngectomized or tracheotemized person to be applied over a tracheostoma includes a heat-moisture exchanger body which communicates with the tracheostoma through an inlet (relative to exhaling) and has contact surface turned toward the person. A substantially flat surface layer on the body faces the neck when the breathing protector is applied to the neck covering the stoma and is dimensioned to extend beyond the stoma to cover also a part of the neck surrounding the stoma. A elate covers a flat end surface on the heat-moisture exchanger body which is sandwiched between the surface layer and the plate. An outlet opening extends along the periphery of the heat-moisture exchanger body between the surface layer and the plate to impart to respiration air at least one component which is substantially parallel with the surface layer.
