    摘要: A cover for BTE (behind-the-ear) hearing aids includes a hollow latex body configured similar to, but slightly smaller than, an arcuate BTE hearing aid. The cover possesses a larger quadrilateral closed end and a smaller open end. Opposite arcuate planar sidewalls are connected by a convexly curved top wall and a concavely curved bottom wall. The quadrilateral closed end extends transversely between the sidewalls and the top and bottom walls. The sidewalls and top and bottom walls taper and merge smoothly at the open end to form a circular opening. The cover is formed by dipping a complimentary shaped former into a liquid latex mixture, curing the latex to form a solid cover, and removing the cover from the former. In use, prongs of an expander tool are inserted into the open end of the cover, the prongs are then moved apart to mechanically stretch the cover, the BTE hearing aid is then inserted into the open end of the cover, and the cover is relaxed and allowed to conform closely to the outer surface of the hearing aid, preventing damage by moisture and other contaminants.
