ABSTRACT:
A breathing aid for laryngotomoy tracheostomy patients includes a filter house made from plastics material, which is provided to receive a replaceable filter and which is made in one piece with a cover having perforations, the cover being provided to close the filter house via a flexible integral hinge strip. The breathing aid includes a hood applicable upon the cover and having a downwardly directed suction channel through which the inhaled air has to pass before it reaches the filter, the hood having a recess which by cooperation with the hinge strip guarantees the correct orientation of the hood and holds it in this position. The filter house can be secured to an adhesive foil which has rectangular or square shape and the filter house is so orientated in relation to the foil that the pivot axis of the hinge will be parallel to one of the sides of the foil.
