Gas curtain for shielding person on an operating table

摘要

An operation area on an operating table is flanked by a blower unit and a suction unit. The blower unit creates several vertically spaced and independently adjustable streams of gas each of which is aspirated by a respective intake of the suction unit. The lowermost stream of gas, which is sterilized, flows just tangent to the operation location on the body of a patient lying on the operating table. The outlets of the blower unit and the intakes of the suction unit are independently adjustable to position the respective gas streams in accordance with the dimensions of the body part being shielded.
