吸引术是医学实践基本环节之一,其目的是抽吸和收集身体中的液体。它经常用在气管分泌物的抽吸、外科手术时液体的吸引及一种在形式上是低压的持续引流。很多吸引液体是被微生物严重污染并且吸引器械的应用具有很大的交叉感染的风险。 Aspiration is one of the basic steps in medical practice. Its purpose is to pump and collect fluids in the body. It is often used in the suction of tracheal secretions, the attraction of liquids during surgery and a continuous drainage that is low in form. Many applications that attract liquids that are heavily contaminated by microorganisms and attract instruments have a great risk of cross-contamination.
