For the protection of an in-the-ear hearing aid against contamination by
ear wax through the acoustic outlet port (34a) or a vent, a replaceable
ear wax guard (36) is inserted in the aid and comprises an essentially
tubular element with a through-going cavity and an abutment collar in one
end for sealing abutment against the hearing aid housing (31). For an easy
and safe insertion and removal of the ear wax guard (36), an applicator is
used, which in one end has a smooth pin for introduction in the
through-going cavity of the ear wax guard (36) and in the other end a
harpoon-shaped catch member. For mounting of the ear wax guard (36) a hose
or tube member serving as acoustic outlet canal (34) is connected to an
abutment collar (33) in abutment with the outside of the hearing aid. The
abutment collar is designed with oversize standard dimensions and adapted
to an individually user-adapted hearing aid housing by preparation of its
periphery edge.
