Saliva ejector (low-volume suction)
Also called: SE, low-volume suction, spit sucker
A thin, bendable straw that gently removes saliva and water.
The saliva ejector is a narrow, flexible suction tip that can rest in the patient's mouth. It removes small amounts of saliva and water but not much spray. Studies found that fluid can flow backward from the line into the mouth if the patient seals their lips around the tip.
How to spot it
- A thin, clear or colored disposable straw bent into a hook, attached to a small hose.
What it is used for
- Bend it to hang under the tongue or along the cheek during procedures.
- Pair it with the HVE when there is a lot of water or spray.
Safety and care
- Do not tell patients to close their lips around the tip.
- Use a new tip for each patient; barrier the hose end.
- Keep the tubing from rising above the patient's mouth, which can let fluid flow back.
