The CONMED 1000 SES Smoke Evacuation
Filtration System is designed to remove smoke
and noxious odors from the smoke plume gener-
ated during the course of laser and electrosurgical
procedures.
The CONMED 1000 SES is designed with a
high suction and high flow rate centrifugal action
pump. The ultra-quiet motor is used to draw the
smoke plume from the surgical site, through the
vacuum tubing and into the CONMED 1000
SES filter cartridge, where the smoke plume is
purified by a series of filters. A single disposable
filter cartridge is used to simplify the installation
and removal during filter changes. This filter is
completely enclosed to further protect the health-
care personnel from potential contamination. The
CONMED 1000 SES filter contains four differ-
ent filter stages within a single housing to decont-
aminate the smoke plume.
5.1 Filtration System
The CONMED 1000 SES filter is used with the
CONMED 1000 SES Smoke Evacuation System.
The first stage of filtration is a prefilter whose
function is to trap and remove gross particulate
and casual fluid.
The second stage of filtration is a VLSI (Very
Large Scale Integrated) grade ULPA (Ultra Low
Penetration Air) filter whose high-tech patented
design is for the purpose of capture of particulates
and micro-organisms down to 0.01mm at an effi-
ciency of 99.99995%. Each ULPA filter is pre-
tested and certified before use.
The third stage of filtration uses virgin coal grade
activated carbon for the removal and adsorption
of odors and toxic gases produced by the burning
tissue. These harmful gases are a health hazard to
those healthcare workers who breathe the gases.
For this reason, the highest quality virgin coal
grade activated carbon is used. This activated car-
bon preferentially removes toxic organic gases
rather than water vapor.
The fourth stage of filtration is expanded foam
and paper media used to trap activated carbon
fines from migrating out of the filter.
As shown in Figure 4, the electrosurgical smoke
enters the CONMED 1000 SES Filter through
the inlet port on the front of the filter. The smoke
is pulled through the four stage filter described
above. The cleaned air exits the filter, passes
through the motor/blower and exits the CON-
MED 1000 SES through the exit port on the bot-
tom of the unit via airways in the unit’s insula-
tion.
5.2 Electronic Control System
Refer to Figure 5, CONMED 1000 SES System
Block Diagram while reading this section.
AC mains power enters the unit through the
Power Entry Module on the rear panel of the
unit. This Power Entry Module contains the
mains cord inlet connector and the main power
switch. Mains power then goes to the circuit
breakers on the rear panel which are connected to
the controller printed wiring board.
The controller printed wiring board contains the
microprocessor, low voltage power supply and
motor/blower control circuitry. The front panel
membrane switch panel is connected to the con-
troller PWB. All user input commands from the
front panel are recognized by the microprocessor,
which in turn controls the motor/blower and the
LED’s on the front panel.
All of the control circuitry for the CONMED
1000 SES Smoke Evacuation System is contained
on the controller PWB. This allows board level
repair of the unit by qualified service personnel.
The Controller PWB’s are pre-calibrated and test-
