1. An apparatus for recording physiological parameters, which can be inserted in an ear canal, comprising:
a) a tube adapted to be introduced into an ear canal; and
b) a housing connected to the tube, wherein the housing has integrated therein at least one sensor device adapted to record a physiological parameter;
wherein the tube comprises a largely cylindrical portion at a distal end of the tube, wherein the largely cylindrical portion is adapted to face toward an eardrum of a user when the apparatus is inserted in an ear canal;
wherein the largely cylindrical portion of the distal end of the tube includes an aperture and at least one sensor opening for the at least one sensor device that is adapted to record a physiological parameter;
wherein the at least one sensor opening is spaced apart from a longitudinal axis LA of the largely cylindrical portion by a distance lsensoropening and is arranged such that when the apparatus is inserted in an ear canal, the at least one sensor opening contacts an inner wall of the ear canal; the apparatus further comprising:
an ear adapter configured to detachably attach to the largely cylindrical portion, wherein the ear adapter comprises a central piece adapted to engage in the aperture of the largely cylindrical portion;
an ear contact surface adapted to engage with an inner wall of an ear canal when the apparatus is inserted in an ear canal; and
an endpiece adapted to connect the central piece and the ear contact surface, wherein the ear contact surface at least partially encloses the distal end of the tube and is attached thereto such that when the apparatus is inserted into an ear canal, the at least one sensor opening comes to lie in close proximity to an inner wall of the ear canal.
