An Electric Suction Machine is a portable, electrically-powered medical device that generates vacuum pressure to remove fluids and secretions from a patient's airway, surgical site, or wound. It is a critical tool for maintaining a patent airway in emergency, surgical, post-operative, and chronic home care settings. The unit consists of a vacuum pump, a disposable collection canister with overflow protection, connecting tubing, and patient-end accessories. Key performance features include adjustable suction pressure, adequate airflow, and often battery backup for reliability. Strict adherence to pressure settings, suction duration, and single-use disposable components is essential for patient safety and infection control.
