Abstract: The present invention discloses a holding device for attachment to the ear of a user, wherein a flexible connecting element arranged between an end piece and a terminal holder ensures that, even when subjected to relatively pronounced loads caused by external effects, such as for example a change in position of the head, the holding device is securely held on the ear without exerting unpleasant pressure on individual anatomical structures of the ear. By virtue of a flexible basic structure, the holding device according to the invention enables use on both ears of a user, without the holding device having to be adapted individually to each ear by a change in structure. In addition, a box suitable for storing the holding device ensures safe storage of the holding device when not in use, serves to keep the holding device ready for immediate use, and prevents deformation of the holding device caused by improper storage.

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 LA of the largely cylindrical portion by a distance lsensoropening. 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.

Abstract: A sensor for measuring a vital parameter in the auditory canal comprising a sensor element (1) and a positioning element (3), both connected to a sensor element attachment (2). The positioning element (3) has a shape that reproduces the inside of the ear and positions the sensor element (1) and sensor element attachment (2) at least partially in the auditory canal (8) in a stable manner. The position of the sensor element (1) in the auditory canal (8) is determined by the depth of penetration of the sensor element attachment (2) in the auditory canal (8). The sensor element (1), the sensor element attachment (2), and the positioning element (3) are arranged at least partially in a housing (4) adapted to the anatomy of the person's head.

Abstract: The invention relates to a sensor for measuring a vital parameter in the auditory canal of a human or of an animal and to a method for determining tissue variables, preferably the oxygen saturation in the blood, particularly for performing pulse oximetry, preferably transmission pulse oximetry, in the auditory canal.
