Chapter 2: Product Outline
1. Product outline
(1)
Intended use
The endoscopic CO2 regulation unit has been designed to be used with Olympus
endoscopes and ancillary equipment for CO2 gas and water feeding.
(2)
Coverage of combination
The product can be combined with wide use video scope for upper digestive tract,
duodenal videoscope, small intestine videoscope, large intestine videoscope, and sigmoid
videoscope from, 150 series, EVIS EXERA 145/160 series, EVIS EXERA Ⅱ 165/180
series, EVIS 240 series, PCF-S, and (scopes in this document refer to EVIS 140 series EVIS LUCERA 260 series ).
2. Characteristics
(1)
The product can be combined with the scopes listed in the coverage of combinations and
perform CO2 gas supply instead of air supply.
(2)
The CO2 gas supply volume is equivalent to the air supply volume of conventional light
source.
(3)
Preparation is easy as the main body and CO2 cylinder can be connected with a specific
high pressure hose.
ISSUE3
(4)
Gas supply start/stop can be operated through a single button.
(5)
Residual pressure of the gas cylinder is displayed in the supply pressure display bar
graph. Flow display is also available while CO2 gas is output from the main body.
(6)
Timer function is also available which buzzes and automatically switches off after a
specified period of time.
(7)
Flow can be adjusted by combined the product with the optional low flow gas tube (MAJ1742, MAJ-1816).
(8)
The product is small sized, compact, and can be mounted on our mobile workstation NP1
and WP1.
