Elastic sensor for measuring vital parameters in the auditory canal

A sensor for measuring a vital parameter in the auditory canal (8) of a person or an animal, comprising:

• a sensor element fixture (2), which is positionable at least partially in the auditory canal (8),
• a sensor element (1), which is connectable to the sensor element fixture (2) and is positionable at least partially in the auditory canal (8), and
• a positioning element (3), suitable for positioning the sensor element fixture (2) in the auditory canal (8), wherein at least one end of the positioning element (3) is connectable to the sensor element fixture (2),
• wherein the position of the sensor element (1) within the auditory canal (8) is determined by the insertion depth of the sensor element fixture (2) in the auditory canal (8), and
• wherein the positioning element (3) exhibits a suitable shape relating to the anatomy of the interior face of the auricle, and is suitable for pushing the sensor element fixture (2) into the interior of the auditory canal such that the sensor is held firmly and a continuous measurement of the vital parameter occurs in the auditory canal (8) characterized in that
• the sensor element (1), the sensor element fixture (2) and the positioning element (3) are arranged at least partially in a housing (4) and the housing (4) is adaptable to the anatomy of at least part of the head of the person or the animal, wherein the housing (4) is at least partially elastic, the housing (4) is rotatable and/or size adjustable, the housing (4) comprises a piston and a guide wherein the piston is at least partially aligned in the guide, the piston and/or the guide are arranged with a material comprising a plastic, a rubber, a silicone and/or an elastomer such that they may be pulled apart in the 0° position and such that a rotation of up to −120° or +120° results in a deadlock, wherein the 0° position lies in a plane parallel to the sagittal plane of the head.
