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;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,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. |
