Definitions
- the invention relates to a cerumen trap for hearing impaired devices according to the preamble of claim 1.
- cerumen traps are already known. Since the sound channel is open towards the auditory canal, cerumen can still penetrate the schail channel and thus clog it and the passages leading to the sound channel. However, this also blocks the passages arranged in a star shape.
- the object of the invention is to improve a cerumen catcher of the type mentioned at the outset in such a way that not only the penetration of cerumen is prevented with great certainty, but also that the cleaning of the cerumen catcher which is still required is facilitated.
- Fig. I schematically shows a greatly enlarged side view of the cylindrical component for a cerumen trap
- Fig. 2 is a plan view of Fig. 1;
- Fig. 3 is a sectional view of FIG. 1;
- Figure 4 is a cap seen from above.
- Fig. Fig. 5 is a sectional view of the cap shown in Fig. 4 and
- the cerumen trap shown in the figures is shown on a very large scale, in reality it has a diameter of almost 4 mm overall.
- the component 1 has several, for example four, angle pieces 4 on its circumference following the connecting piece. Of course, there can only be 3 or more than 4. These angle pieces are arranged evenly on the circumference of component 1. At their upper end, the elbows have locking lugs 5, while a horizontally extending base section 6 is provided at the lower end, the meaning of which will be explained below.
- the cap 7 shown in FIGS. 4 and 5 can be placed on this component.
- the cap 7 has on its inner vertical surface a preferably, but not necessarily, all-round locking groove.
- FIGS. 6A and 6B show the new cerumen trap in a side view, partly in section, and in a view from above. It can now be clearly seen that a cavity 9 is formed between the upper edge of the component 1 and the underside of the cap 7. The arrows drawn in both figures clearly show the course of the scarf outlet.
- the size of the cavity 9 can be varied to a small extent by the choice of the dimensions of the angle pieces and the locking lugs or the location of the locking groove 8 in the cap 7.
- the invention can also be implemented by mechanical reversal.
- the component would then be smooth on its surface facing the ear canal and would have a locking groove on its outer surface.
- the cap 7 would then have a number of latching lugs in connection with an equal number of spacers on the inner wall. These would then not only prevent the cap from being inserted too deeply, but would also have a clamping effect.
