Abstract

Bei medizinischen Geräten, welche am Körper getragen werden, besteht die Gefahr, dass durch Feuchtigkeit, Schweiss etc. gewisse Teile und Komponenten des Gerätes korrodieren können bzw. nicht mehr funktionieren. Speziell führt das Eindringen von Feuchtigkeit und Schweiss in Hörgeräten zu Korrosion, beispielsweise der Batterie, und in einigen Fällen zu Störungen der Elektronik. Allerdings wird die überragende Mehrheit dieser medizinischen Geräte mit Zink-Luft-Batterien betrieben, so dass es nicht möglich ist, das Gerät hermetisch abzudichten, da die Batterie eine konstante Sauerstoffversorgung benötigt, um die Betriebsspannung aufrecht zu erhalten. Entsprechend wird vorgeschlagen, zum flüssigkeitsdichten Abdichten von Kleinstspalten, Ritzen, Kapillaren und/oder Öffnungen (11) in Gehäusewandungen die Gehäusewandung mindestens im Bereich der Spalte, Ritze, Öffnung oder Kapillare mit einer hydrophoben Beschichtung zu versehen, wobei eine gewisse Gasdurchlässigkeit erhalten bleibt. Die hydrophobe Beschichtung wird erzeugt beispielsweise mittels hydrophoben Nanopartikeln über einen sogenannten Sol-Gel Prozess. Die Beschichtung kann aber auch mittels hydratisierten Silanen oder fluorhaltigen Polykondensaten erfolgen. Weiter vorgeschlagen wird, die Beschichtung mittels Niedertemperatur-Plasmaverdampfverfahren zu applizieren, wobei beim Beschichten eine kompakte Polymerschicht auf der Gehäusewandung abgeschieden wird.

Figure 00000001
With medical devices that are worn on the body, there is a risk that certain parts and components of the device may corrode or no longer function due to moisture, sweat, etc. In particular, the penetration of moisture and sweat in hearing aids leads to corrosion, for example of the battery, and in some cases to malfunctions in the electronics. However, the vast majority of these medical devices are powered by zinc-air batteries, so it is not possible to hermetically seal the device because the battery requires constant oxygen supply to maintain the operating voltage. Accordingly, it is proposed for the liquid-tight sealing of small gaps, cracks, capillaries and / or openings (11) in the housing walls to provide the housing wall with a hydrophobic coating at least in the area of the gaps, crack, opening or capillary, while maintaining a certain gas permeability. The hydrophobic coating is produced, for example, by means of hydrophobic nanoparticles using a so-called sol-gel process. However, the coating can also be carried out using hydrated silanes or fluorine-containing polycondensates. It is further proposed to apply the coating by means of a low-temperature plasma evaporation process, a compact polymer layer being deposited on the housing wall during coating.
