Definition : Aspirators designed to provide suction for evacuation of gas, body fluids, or foreign materials that may accumulate between the lung and chest wall (i.e., pleural space). These aspirators typically consist of a powered low-vacuum (> 50 mm Hg) and high-volume (> 20 liter/min) pump; collection canisters; plastic tubes connecting the components each other; an overflow protection and/or bacteria filter; and suction tubing (e.g., tubes, catheters, cannulae). The devices can be line-or battery-powered, mobile or portable. Thoracic aspirators are intended to evacuate gas and body fluids after thoracic surgery, trauma in the chest, or after cardiac bypass surgery. They are used mainly when suction from a central vacuum system is not available or appropriate.
