Portable Spatula Tongue Depressor

The devices are designed to be kept in a clean, but not necessarily sterile, environment; tongue depressors do not need to be sterile as a general rule because they are not being introduced to a highly vulnerable area of the body. however, they are usually discarded after use to reduce the risk of passing microorganisms between patients, and some companies also make individually packaged tongue depressors which are intended to be as clean as possible.
