System and method for designing hearing aid components with a flexible cover

A method and appertaining system for implementing the method is provided for designing hearing aids having flexible parts. Three-dimensional data is provided that is related to both a soft part and a hard part of a hearing aid component into a computer-based system. Additionally, information is entered related to material characteristics for both the soft part and the hard part of the component. A component within the hearing aid shell is placed and moved in a model generated by the system. Forces, stresses, and/or amount of deformation for parts of the component based on the location of the component and at least one of another component and the shell are calculated, and the three-dimensional data model of the shell is revised based upon the calculated degree of deformation, forces, and/or stresses.

IMPLANT INFECTION CONTROL

Embodiments presented herein are generally directed to a perioperative implant cover configured to cover at least a portion of an implantable component during portions of the perioperative period (i.e., preoperative, intraoperative, and postoperative phases of surgery) in which the implantable component is susceptible to bacteria contamination. By covering the implantable component during these portions of the perioperative period, the cover reduces the possibility of bacteria contamination and subsequent perioperative colonization.

The application relates to a portable electronic device comprising a) a folded substrate carrying components of the device, and b) another, separate component having a fixed outer contour, and c) a housing for enclosing said folded substrate and said separate component, said housing having an inner contour, wherein said folded substrate is folded from a planar substrate along a folding line, said folded substrate exhibiting outer edges comprising a folded edge following said folding line. The application further relates to a method of manufacturing a folded substrate. The object of the present application is to facilitate miniaturization of a portable electronic device, such as a hearing aid. The problem is solved in that the folded substrate is shaped to provide that at least one of said outer edges follow(s) the fixed outer contour of the separate component and/or the inner contour of said housing. This has the advantage of providing a larger area on the substrate to place components and soldering points thereby improving the use of the available space in the portable electronic device. The invention may e.g. be used in electronic devices where volume utilization is an important design parameter, e.g. hearing aids comprising a part adapted for being mounted in an ear canal of a user, e.g. in the bony part of the ear canal.
