A medical aspirator is a suction machine used to remove mucus, blood, and other bodily fluids from a patient. They can be used during surgical procedures but an operating theater is generally equipped with a central system of vacuum tubes.[1] Most aspirators are therefore portable, for use in ambulances and nursing homes, and can run on AC/DC or battery power. They consist of a vacuum pump, avacuum regulator and gauge, a collection canister, and sometimes abacterial filter. Plastic tubing is used to continuously draw fluid into the collection canister.
In the past manually operated aspirators were used such as Potain's aspirator.[2]
