Abstract
A saliva suction device is provided comprising a plastic injection-molded part which configures a coupling for connection to a suction hose, possibly via an adapter, and is plugged on the suction hose or connected to the suction hose in another manner and particularly configures a lingual shield. A first suction channel extends through the molded part. A massive, i.e. non-porous, soft body is plugged on or at the plastic molded part and connected to the molded part in a form-fitting manner, through which soft body a second suction channel extends which is vertically offset relative to the first suction channel. Particularly on the side of the second suction channel, which is opposite the first suction channel, a suction area with at least one suction opening for saliva is configured in the soft body.
Claims25
A saliva suction device comprising
- a plastic injection-molded part configured with a coupling for connection to a suction hose, the plastic injection-molded part configured to be plugged onto the suction hose or connected to the suction hose, the plastic injection-molded part having a first suction channel extending through it,
- a lingual shield integral or part of the plastic injection molded part,
- a non-porous, soft body plugged on or at the plastic injection-molded part and connected to the injection-molded part in a form-fitting manner, and having a second suction channel that is vertically offset relative to the first suction channel and which second suction channel is fabricated of a non-porous material,
- wherein on a side of the second suction channel, which is opposite the first suction channel, a suction area with at least one suction opening for saliva is configured in the soft body,
- wherein there is a recess between the lingual shield and the non-porous soft body,
- wherein the lingual shield extends along a concave upper side of the curved soft body and is spaced apart from the curved soft body by less than 8 mm, and comprises a curved edge following the course of the curved soft body, and
- wherein the soft body protrudes beyond the lingual shield at a distal end.
A saliva suction device comprising
- a plastic injection-molded part configured with a coupling for connection to a suction hose, the plastic injection-molded part configured to be plugged onto the suction hose or connected to the suction hose, the plastic injection-molded part having a first suction channel extending through it,
- a lingual shield integral or part of the plastic injection molded part,
- a non-porous, soft body plugged on or at the plastic injection-molded part and connected to the injection-molded part in a form-fitting manner, and having a second suction channel that is vertically offset relative to the first suction channel and which second suction channel is fabricated of a non-porous material,
- wherein on a side of the second suction channel, which is opposite the first suction channel, a suction area with at least one suction opening for saliva is configured in the soft body,
- wherein there is a recess between the lingual shield and the non-porous soft body,
- wherein the at least one suction opening in the soft body comprises a plurality of slits as suction openings and a plurality of smaller, in comparison to the size of the slits, suction openings or holes adjacent to each slit, and
- wherein at least one arrangement of a slit and at least one of the adjacent smaller suction openings forms a predetermined breaking point.
