Do not reuse the syringe. Doing so may cause infection. Used syringes shall be
discarded according to the applicable laws of your country or region.
If the syringe should cause any abnormalities to the lips or oral cavity, stop
using it immediately.
CAUTION
When you sample oral gas immediately after using mouth washes and/or tooth

Breathe through the nose, while keeping the oral cavity sealed and unventilated for at
