7. The dental aspiration device of claim 6 , further including substantially cylindrical valve members received in the laterally disposed holes, valve controls including levers to control pivotal movement of the valve members in the laterally disposed holes, and holes in the substantially cylindrical valve members to selectively communicate with vacuum channels for controlling aspiration through the vacuum channels.
8. The dental aspiration device of claim 7 , wherein at least one of the distal portions of the substantially L-shaped inside housing and the substantially L-shaped outside housing includes a pair of circular hinge members having holes aligned with the laterally disposed holes for pivotally connecting the substantially L-shaped inside housing and the substantially L-shaped outside housing together.
9. The dental aspiration device of claim 2 , wherein the distal portion of the substantially L-shaped inside housing includes an underside with locking barbs extending therefrom.
10. The dental aspiration device of claim 5 , wherein the valve block includes an additional lateral hole and the base includes at least one additional hole aligned with the additional lateral hole of the valve block, and further including a dowel pin disposed in the additional lateral hole of the valve block and at least one additional hole of the base for securing the base and the valve block together.
11. A method of cleaning the dental aspiration device of claim 10 , comprising:
removing the dowel pin from the additional lateral hole of the valve block and at least one additional hole of the base;
removing the substantially cylindrical valve members and valve controls from the laterally disposed holes;
separating the valve block from the base;
separating the substantially L-shaped outside housing and the substantially L-shaped inside housing from each other;
sterilizing the substantially cylindrical valve members and valve controls, valve block, substantially L-shaped outside housing, and the substantially L-shaped inside housing.
12. A method of cleaning the dental aspiration device of claim 1 , comprising:
unlocking the distal portions of the outside housing and the inside housing from each other;
pivoting and separating the outside housing and the inside housing from each other about the hinge connection mechanism so that the vacuum channels are exposed;
cleaning the vacuum channels.
13. A method of using the dental aspiration device of claim 9 , comprising:
connecting an intraoral device having a connection section with slots to the dental aspiration device by sliding the connection section of the intraoral device over the distal portion of the dental aspiration device and engaging the slots in the connection section of the intraoral aspiration device with the locking barbs of the distal portion of the dental aspiration device;
connecting the dental aspiration device to a suction hose;
inserting the intraoral device into the mouth of a patient;
aspirating fluids from the patient's mouth using the intraoral device and the dental aspiration device.
14. A dental aspiration device, comprising:
an inside housing having a proximal portion and a distal portion with an interior surface;
an outside housing having a proximal portion and a distal portion with an interior surface;
at least one of the interior surfaces of the inside housing and the outside housing including vacuum channels;
a hinge connection mechanism hingeably connecting the proximal portions of the inside housing and the outside housing; and
a locking mechanism for removably attaching the distal portions of the inside housing and the outside housing to each other,
wherein the locking mechanism includes a locking barb connection mechanism with locking barbs and locking barb receptacles that removably receive the locking barbs, the locking barbs and locking barb receptacles including respective downwardly and rearwardly angled surfaces operatively associated with each other to lock the distal portions together, and
at least one of the distal portions of the inside housing and the outside housing includes one or more tangs extending distally therefrom to facilitate separation of the distal portions.
15. A dental aspiration device, comprising:
an inside housing having a proximal portion and a distal portion with an interior surface;
an outside housing having a proximal portion and a distal portion with an interior surface;
at least one of the interior surfaces of the inside housing and the outside housing including vacuum channels;
