Description of function
The IES 2 is an electrical medical device which purifies the air of smoke and
gas particles which result from the vaporization of human and animal tis-
sue. This smoke typically arises during the use of laser and electrosurgical
devices and generally consists of water vapor, aerosols and organic gases.
The IES 2 improves the ambient conditions in the OR by:
• reducing the amount of dust by removing respirable particles,
• improving vision,
• removing unpleasant-smelling gases,
• evacuating and filtering bioaerosols.
The IES 2 extracts the smoke-laden air via a device on the surgical applied
part or via a hand-held tube which is separate from the device and posi-
tioned near the applied part. The evacuated air is then purified of smoke
and gas particles by means of a high-performance filter, and recirculated
to the ambient air.
Air purification refers to particles such as aerosols, which are captured by
an ULPA high-performance particle filter, and also to organic gases, which
are detected by an odor that humans find unpleasant, among other things,
and which can be extracted by a special gas filter..
