Apparatus, which is insertable into an ear canal, for detecting physiological parameters

Abstract

The invention relates to an apparatus for recording physiological parameters, which can be inserted in an ear canal. The apparatus is designed with a tube, which is to be introduced into the ear canal, and a housing, which is connected to the tube. The tube comprises a largely cylindrical portion at a distal end that faces toward the eardrum when being worn. At least one sensor device for recording physiological parameters is integrated in the housing. The largely cylindrical portion is designed with at least one sensor opening for at least one sensor component for recording physiological parameters. The at least one sensor opening is spaced apart from the longitudinal axis Lof the largely cylindrical portion by a distance l. A receiver device for outputting sound signals may also be integrated in the apparatus, so that the apparatus is suitable for applying sound to the eardrum. The invention further relates to an ear adapter for detachable attachment to the largely cylindrical portion of the tube of the apparatus, wherein the ear adapter is attached thereto in such a way that the at least one sensor opening comes to lie in close proximity to an inner surface of the ear canal or comes into contact therewith.
