Abstract
A portable saliva compensation device is provided with a portable carrying case holding a vacuum pump, and a portable power supply for providing power to vacuum pump. An electrical control circuit is connected to the portable power supply and the pump. A saliva collection device is positioned at or below a user's mouth for collecting excess saliva and conveying it to a hollow tube connecting between the saliva collection device and the vacuum pump. A saliva detection switch in the saliva collection device is coupled to the electrical control circuit to activate the vacuum pump when saliva is detected in the saliva collection device. This draws the saliva from the collection device through said hollow tube and into a collection reservoir.
