Intraoral device and method of use
An intraoral device includes a flexible body having an upper front flap including evacuation holes and a upper edge; an upper rear flap forming an upper pocket with the upper front flap and including internal channels and a upper edge separated from the upper edge of the upper front flap to form an upper pocket opening, the internal channels terminating in grooves along the upper edge; a lower front flap including evacuation holes and a lower edge; a lower rear flap forming a lower pocket with the lower front flap and including internal channels and a lower edge separated from the lower edge of the lower front flap to form an lower pocket opening, the internal channels terminating in grooves along the lower edge.
1. An intraoral device, comprising:
a flexible body, comprising:
an upper front flap including an upper edge;
an upper rear flap forming an upper pocket with the upper front flap, the upper rear flap including an upper edge separated from the upper edge of the upper front flap to form an upper pocket opening;
at least one of the upper front flap and the upper rear flap including internal channels;
a lower front flap including a lower edge;
a lower rear flap forming a lower pocket with the lower front flap, the lower rear flap including a lower edge separated from the lower edge of the lower front flap to form an lower pocket opening;
at least one of the lower front flap and the lower rear flap including internal channels;
wherein the internal channels of at least one of the upper front and rear flaps and the lower front and rear flaps terminating in grooves along at least one of the upper edges and the lower edges, in a non-vacuum state the upper pocket opening and lower pocket opening are open, and in a vacuum state the upper pocket opening and lower pocket opening are substantially sealed closed so that aspiration of fluids from a patient's mouth occurs through the grooves, which become fluid inlets for drawing fluids through the internal channels.
2. The intraoral device of claim 1 , further including evacuation holes in at least one of the front flaps and the rear flaps.
3. The intraoral device of claim 2 , wherein the evacuation holes are in the front flaps and not in the rear flaps.
4. The intraoral device of claim 2 , wherein the evacuation holes communicate with and are aligned with the internal channels.
5. The intraoral device of claim 1 , wherein the grooves are in the rear flaps at an intersection of the edges and the internal channels of the rear flaps and not in the front flaps.
6. The intraoral device of claim 1 , wherein the internal channels are vertical channels.
7. The intraoral device of claim 1 , wherein the internal channels form corresponding external ridges in the rear flaps.
8. The intraoral device of claim 1 , wherein the intraoral device includes a horizontally and longitudinally extending spine, an upper internal evacuation channel disposed above the spine in the upper pocket, and a lower internal evacuation channel disposed below the spine in the lower pocket.
9. The intraoral device of claim 8 , wherein the intraoral device includes an upper portion above the spine and a lower portion below the spine that are vertically symmetrical.
10. The intraoral device of claim 1 , wherein the lower rear flap and the upper rear flap define a profile, the lower front flap and the upper front flap define a profile, and the profile of the lower rear flap and the upper rear flap is the same as the profile of the lower front flap and the upper front flap except for the grooves.
11. A method of using the intraoral device of claim 1 , comprising: inserting the intraoral device into a patient's mouth so that a upper edges of a upper flaps contact an upper part of the patient's mouth and the lower edges of the lower flaps contact a lower part of a tongue within the mouth of the patient; applying vacuum state to the intraoral device so that the upper pocket opening and lower pocket opening are substantially sealed closed and the grooves become fluid inlets for drawing fluids through the channels; aspirating fluids from the patient's mouth through the grooves in the intraoral device.
