An assembly of devices designed to evacuate fluid, tissue, gas, or other foreign materials from a body cavity or lumen by means of suction. It generally consists of a suction pump powered by compressed air or oxygen from a hospital's central gas system, tubing, plastic/glass collection container(s), a vacuum gauge, a regulator, an overflow trap, a moisture filter, and possibly a microbial filter. The pressurized gas enables the pump to create a vacuum in the suction tubing, which is inserted into the body for the removal of materials into the collection container. This system can be used in a wide variety of hospital or other healthcare settings.
An assembly of vacuum-powered devices, which includes a surgically invasive component, designed to aspirate unwanted materials (e.g., debris, tissues, fluids) from body cavities/wounds during a surgical procedure (e.g., general surgery, laparoscopy); it may in addition have non-surgical applications. It is connected via dedicated tubing to the terminal unit (wall outlet) of a vacuum pipeline system and relies on the healthcare facility’s central vacuum system. It includes a vacuum suction regulator which controls negative pressure for the aspiration, collection containers, and patient contact devices (e.g., handpiece/tip); it typically also includes tubing and microbial/hydrophobic filters.
