Intraoral device
An intraoral device includes a one-piece, flexible, injection molded body made of a single homogeneous material. The body includes upper front and rear flaps, and lower front and rear flaps. Upper edges of the front flaps and lower edges of the lower flaps are sealed by respective upper and lower parts of a patient's mouth to form upper and lower evacuation channels when the body is disposed within the patient's mouth. Evacuation holes in the flaps are in communication with the evacuation channels. A connection section is in communication with the evacuation channels and is configured to extend outside of the patient's mouth to connect with a vacuum source for evacuating fluid from the patient's mouth through the evacuation holes and the evacuation channels.
1. A one-piece, injection-molded intraoral device, comprising:
a one-piece, flexible, injection molded body made of a single homogeneous material, the body including
a spine;
an upper front wall;
an upper rear wall separated from the upper front wall by a gap,
a lower front wall;
a lower rear wall separated from the lower front wall by a gap;
the upper walls joined along the spine to form an upper evacuation channel;
the lower walls joined along the spine to form a lower evacuation channel;
one or more evacuation holes in at least one of the upper walls and in communication with the upper evacuation channel;
one or more evacuation holes in at least one of the lower walls and in communication with the lower evacuation channel, and
a connection section in direct communication with both the upper evacuation channel and the lower evacuation channel and configured to extend outside of the patient's mouth to connect with a vacuum source for evacuating fluid from the patient's mouth through the evacuation holes and the evacuation channels.
2. The intraoral device of claim 1 , wherein the intraoral device includes a flexible bite piece where the one-piece, flexible, injection molded body and the connection section join.
3. The intraoral device of claim 2 , wherein the flexible bite piece extends rearwardly toward the rear of the patient's mouth when the intraoral device is positioned within the patient's mouth for use.
4. The intraoral device of claim 2 , wherein the flexible bite piece includes at least 15% vertical compressibility.
5. The intraoral device of claim 2 , wherein the flexible bite piece includes at least 15% longitudinal displaceability.
6. The intraoral device of claim 2 , wherein the flexible bite piece includes at least 6% lateral displaceability.
7. The intraoral device of claim 2 , wherein the flexible bite piece includes at least 15% vertical compressibility, at least 15% longitudinal displaceability, and at least 6% lateral displaceability.
8. The intraoral device of claim 1 , wherein the body includes an illumination member to be optically coupled to a light source for illumination of an interior of the patient's mouth.
9. The intraoral device of claim 1 , wherein the body terminates distally in a cheek portion that flexes when the body is disposed in the patient's mouth.
10. The intraoral device of claim 1 , wherein the lower walls form a tongue retractor portion.
11. A one-piece, injection-molded intraoral device, comprising:
a one-piece, flexible, injection molded body made of a single homogeneous material, the body including
an upper front wall;
an upper rear wall separated from the upper front wall by a gap,
a lower front wall;
a lower rear wall separated from the lower front wall by a gap;
the upper walls joined to form an upper evacuation channel;
the lower walls joined to form a lower evacuation channel that is not planar with the upper evacuation channel;
one or more evacuation holes in at least one of the upper walls and in communication with the upper evacuation channel;
one or more evacuation holes in at least one of the lower walls and in communication with the lower evacuation channel,
a connection section in communication with the upper evacuation channel and the lower evacuation channel and configured to extend outside of the patient's mouth to connect with a vacuum source for evacuating fluid from the patient's mouth through the evacuation holes and the evacuation channels; and
a flexible bite piece where the one-piece, flexible, injection molded body and the connection section join, the flexible bite piece having a surface to be engaged by several teeth of a user and being vertically compressible, longitudinally displaceable, and laterally displaceable, and extending substantially perpendicularly and rearwardly from where the one-piece, flexible, injection molded body and the connection section join toward the rear of the patient's mouth when the intraoral device is positioned within the patient's mouth for use.
12. The intraoral device of claim 11 , wherein the body includes an illumination member to be optically coupled to a light source for illumination of an interior of the patient's mouth.
13. The intraoral device of claim 11 , wherein the body terminates distally in a cheek portion that flexes when the body is disposed in the patient's mouth.
14. The intraoral device of claim 11 , wherein the lower walls form a tongue retractor portion.
15. A one-piece, injection-molded intraoral device, comprising:
a one-piece, flexible, injection molded body made of a single homogeneous material, the body including
an upper front wall;
an upper rear wall separated from the upper front wall by a gap, the upper front wall and the upper rear wall including a wave-shaped top edge,
a lower front wall;
a lower rear wall separated from the lower front wall by a gap, the lower front wall and the lower rear wall including a wave-shaped bottom edge;
the upper walls joined to form an upper evacuation channel;
the lower walls joined to form a lower evacuation channel;
one or more evacuation holes in at least one of the upper walls and in communication with the upper evacuation channel;
one or more evacuation holes in at least one of the lower walls and in communication with the lower evacuation channel,
an illumination member to be optically coupled to a light source for illumination of an interior of the patient's mouth; and
a connection section in communication with the upper evacuation channel and the lower evacuation channel and configured to extend outside of the patient's mouth to connect with a vacuum source for evacuating fluid from the patient's mouth through the evacuation holes and the evacuation channels.
16. The intraoral device of claim 15 , wherein the body terminates distally in a cheek portion that flexes when the body is disposed in the patient's mouth.
17. The intraoral device of claim 15 , wherein the lower walls form a tongue retractor portion.
