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 evacuation holes and an 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 of the upper rear flap;
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 of the lower rear flap,
wherein 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 the patient's mouth occurs through the evacuation holes in the front flaps and grooves, which become fluid inlets for drawing fluids through the channels, of the rear flaps.
2. The intraoral device of claim 1 , wherein the evacuation holes are in the front flaps and not in the rear flaps.
3. 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.
4. The intraoral device of claim 1 , wherein the internal channels are vertical channels.
5. The intraoral device of claim 1 , wherein the internal channels form corresponding external ridges in the rear flaps.
6. The intraoral device of claim 1 , wherein the evacuation holes communicate with and are aligned with the internal channels.
7. 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.
8. The intraoral device of claim 1 , wherein the intraoral device includes an upper portion above the spine and a lower portion below the spine that are vertically symmetrical.
9. A method of using the intraoral device of claim 1 , comprising:
inserting the intraoral device into the patient's mouth so that the upper edges of the 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 along the upper edge of the upper rear flap and along the lower edge of the lower rear flap become fluid inlets for drawing fluids through the channels of the upper rear flap and lower rear flap;
aspirating fluids from the patient's mouth through the evacuation holes in the front flaps and into the channels through the grooves.
10. 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 and an upper edge separated from the upper edge of the upper front flap to form an upper pocket opening, the upper rear flap including grooves along the upper edge;
a lower front flap including a lower edge;
a lower rear flap forming a lower pocket with the lower front flap and a lower edge separated from the lower edge of the lower front flap to form an lower pocket opening, the lower rear flap including grooves along the lower edge,
wherein 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 the patient's mouth occurs through the grooves, which become fluid inlets in the upper rear flaps and lower rear flaps for drawing fluids into the intraoral device.
11. 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.
12. The intraoral device of claim 10 , 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.
