An Electric Trolley Type Suction Apparatus is a medical device used to remove blood, mucus, saliva, vomit, and other fluids from a patient's airway or surgical site. It generates controlled negative pressure to ensure effective suction, helping maintain a clear airway and improving patient safety during medical procedures. The device is mounted on a trolley, making it easy to move between hospital departments and patient care areas. The suction apparatus is widely used in operating rooms, intensive care units (ICUs), emergency departments, wards, and ambulances. It features a powerful electric motor, adjustable vacuum pressure, collection jars, suction tubing, and a pressure gauge for accurate monitoring. Many models also include overflow protection, antibacterial filters, and safety alarms to ensure reliable and hygienic operation.
