Definitions

  • the present invention relates to a method for liquid-tight sealing of small gaps, cracks and / or openings in the housing walls, uses of the Process, housing of electrical or electronic Devices, having gaps, capillaries, cracks, openings and the like, which prevent the ingress of liquid must be sealed, but not against gas permeability, and a battery compartment of a hearing aid.
  • DE 19502994A1 describes a waterproof hearing aid described in which the property of watertightness through complex design measures such as seals and membranes is reached.
  • DE 3834316C1 describes a completely waterproof hearing aid, but shows in Not in detail compared to the previous patent application on how waterproofness is achieved and lay greater emphasis on the execution of the waterproof Controls.
  • the US 005249234A and US 6510230B2 are different Approaches described to BTE devices using a Protect cover from moisture. This protective cover Depending on the version, also contains welding or moisture absorbing fabrics.
  • US 20020181725A1 describes a condenser microphone described with a hydrophobic membrane to a Prevent and stick together with the backplate different methods of how this hydrophobization is achieved can be.
  • US 2002100605 describes a hydrophobic coating for housings of electrical devices, in particular in relation on surge arresters. Again in more Publications are made from hydrophobic coatings Substrates such as plastics, wood, concrete, etc. described, but in which the above Problem is not an issue.
  • Specially medical devices worn on the body are, like pulse rate monitors, invasive Blood property sensors, such as oximetry sensors, Heart rate monitors, hearing aids and the like are in the Rule complex apparatus, which consists of a variety individual, mechanical and electronic components exist that are manufactured in various processes and then be assembled. Because of the mechanical Tolerances of the injection molded plastic parts, which in the Most cases for housings, battery covers, switches, and Like. Are used, also arise in the assembled Condition of the devices always microscopic capillary gaps between the individual components.
  • the option of hearing aid fails to build water-repellent hydrophobic materials, which wettability and thus penetration of liquid through capillary gaps would reduce the fact that such materials as e.g. Teflon, neither with the usual procedures can still be edited meet mechanical and aesthetic criteria.
  • Figure 1a shows the contact angle of water on a untreated or uncoated surface 3, such as for example a polymer which for Hearing aid components is used.
  • a untreated or uncoated surface 3 such as for example a polymer which for Hearing aid components is used.
  • Polymers used are polyamide, ABS, etc.
  • the According to FIG. 1a, the contact angle is clearly below 80 °.
  • FIG. 11 A capillary gap is shown schematically in section in FIG 11, which is shown, for example, in a hearing device housing wall 7 can be formed.
  • FIGS. 1a and 1b now clearly show that a Water drops according to Figure 1a with ease through the Capillary 11 can get through, while the Water drops according to Figure 1b on the surface of the Housing wall remains by penetrating through the Capillary 11 is impossible. But since there are no sealants, such as rubber seals and the like. in the Capillary 11 are arranged, the remains Get gas permeability.
  • FIG 3 shows in section the area of a battery compartment a conventional hearing aid, which against Penetration of liquid is sealed. It is now important that everyone in the area of the battery compartment 19 arranged housing parts with a hydrophobic Coating are provided. These parts include the Battery cover 13, the aforementioned battery compartment 19, the Housing 23 and the function switch 21.
  • the individual components are after their manufacture or Delivery and coated before installation in a hearing aid.
  • a housing as shown for example in Figure 3, This means, for example, that it is after injection molding cleaned and pretreated if necessary to then using one of the methods described later to be coated hydrophobically.
  • FIG. 4 shows a further embodiment of a Battery compartment from a hearing aid and turn denotes those housing parts or components which are to be provided with a hydrophobic coating.
  • This Parts include, for example, a functional or Button 31, the battery cover 33 and a frame 35.
  • Nanoparticles with hydrophobic and oleophobic properties and their applications were also used in DE10051182A1, DE 19544763A1 or DE19948336A1.
  • Other methods for the hydrophobic coating of Polymer surfaces can be found in US 2002 / 0192385A1 or DE10106213A1.
  • the coating is carried out using low-temperature plasma evaporation processes. It is the same
  • the surface is cleaned and activated (e.g. 02 plasma) and then coated.
  • the Coating will either consist of a compact polymer layer a fluorine-containing polymer applied to the component or a hydrophobic molecule directly to the Component plastic pinned.
  • hydrophobic coatings for example in The area of a battery compartment can affect the vulnerability Corrosion in a small electronic device, such as for example a medical device, such as in particular a hearing aid, by preventing the Liquid ingress reduced or even excluded become.
  • the application of the method according to the invention is pending old products already on the market possible.
  • the Improving fluid resistance is possible without Design changes.
  • a device can be subsequently serviced can be retrofitted with hydrophobized components.
  • Service intervals due to contamination or Corrosion can be prolonged, i.e. the device over a longer lifespan.
