Device for taking an impression of a subject's ear minimizes risk of damage on the eardrum when the impression is made. The device comprises a nozzle having a first essentially tubular part that has a centre axis and a side wall. The first tubular part has also a first end intended to be inserted into a subject's ear, a first opening for the outlet of impression material, and a second end connected to a supply member for impression material to the tubular part. The first opening has a centre axis that is essentially perpendicular to the centre axis of the first tubular part at the point where the two centre axes intersect each other, alternatively has a direction, as seen from the centre axis of the first tubular part through the side wall, from said first end. The first opening is preferably arranged in the side wall of the tubular part.
Device for taking impressions of a subject's ear, comprising a nozzle having an essentially tubular part that has a centre axis and a side wall, said tubular part comprising a first end intended to be inserted into a subject's ear, a first opening for the outlet of impression material, as well as a second end connected to a supply member for impression material to the tubular part, wherein said first opening has a centre axis that is essentially perpendicular to the centre axis of the tubular part alternatively has a direction, as seen from the centre axis of the tubular part through the side wall, from said first end, and wherein said tubular part comprises a plurality of openings serving as outlets for impression material.
Device for taking impressions of a subject's ear, comprising a nozzle having an essentially tubular part that has a centre axis and a side wall, said tubular part comprising a first end intended to be inserted into a subject's ear, a first opening for the outlet of impression material arranged in said first end, as well as a second end connected to a supply member for impression material to the tubular part, wherein said tubular part, in the vicinity of said first end, is curved at an angle that is equal to or greater than 90° so that said first opening is essentially directed toward the mouth of the auditory canal when said tubular part is inserted in a subject's ear.
Device for taking impressions of a subject's ear, comprising a nozzle having an essentially tubular part that has a centre axis and a side wall, said tubular part comprising a first end intended to be inserted into a subject's ear, as well as a second end connected to a supply member for impression material to the tubular part, wherein the tubular part comprising a plurality of openings serving as outlets of impression material, said openings arranged in the side wall of the tubular part and distributed along an extension of the tubular part adapted to be inserted into the subject's ear when the impression is made.
Method for taking an impression of a subject's ear, comprising supplying impression material to the ear by a device comprising a nozzle having an essentially tubular part that has a centre axis and a side wall, said tubular part comprising a first end intended to be inserted into a subject's ear, a first opening for the outlet of impression material, as well as a second end connected to a supply member for impression material to the tubular part, wherein said first opening has a centre axis that is essentially perpendicular to the centre axis of the tubular part alternatively has a direction, as seen from the centre axis of the tubular part through the side wall, from said first end, and wherein said tubular part comprises a plurality of openings serving as outlets for impression material, and
