A suction machine in hospitals is a medical device used to remove substances like mucus, blood, saliva, vomit, or other secretions from a patient’s airway or surgical site.
Main functions:
1. Airway clearance – Helps patients who cannot cough or clear secretions by themselves (e.g., during surgery, after trauma, or in critical care).
2. Assists breathing – Keeps the airway open so oxygen can flow freely to the lungs.
3. Surgical use – Removes blood or fluids from the operation site so surgeons can see clearly.
4. Emergency use – In ambulances or ERs, it quickly clears vomit or fluids to prevent choking or aspiration.
5. Wound care – Special suction machines are used in negative pressure wound therapy to promote healing by drawing out fluids and infection
In short: a suction machine helps keep airways clear and surgical fields visible, i
