The plastic parts (handle, sliding cover and support) are manufactured with sturdy, safe medical grade plastic. The collection paper is assembled to the handle in a cleanroom environment and attached to the handle with sonic welding. The handle is snapped into the support and the device is heat sealed inside the protective outer package. The device is then treated with E-Beam radiation in accordance with FDA Quality System Regulations.

Custom labeling can be applied to the handle for recording subject information. The top of the sliding cover has enough surface area for applying barcode label. The sliding cover provides protection to the paper and allows air flow ventilation for drying the paper.

To use the device:

1. Remove the device from the protective outer package and insure the sliding cover is in the "down" position, exposing the collection paper. Instruct the subject to hold the device in one hand with the thumb on the back of the support. It is recommended to use gloves when handling and giving the device to the subject for testing.
2. Instruct the subject to open and insert the device into the mouth; placing the collection paper against the inside of the cheek.
3. Instruct the subject to apply force with the thumb and drag the device out of the mouth; repeating this action 7 more times. Don't rub the collector back and forth against the cheek.
4. After collection move the sliding cover to the "Up" position to protect the collection paper.
