IV. Product Features
• Internal CO
2
warmer eliminates cold CO
2
• Includes control for optional water bottle warmer to maintain water at close to body
temperature
• Stackable with the ENDO STRATUS® irrigation pump
• Standard male luer lock output
• Uses standard “D” or “E” size CO
2
cylinders
• Accepts input from wall CO
2
with standard DISS type connection
• Usable at CO
2
input pressures lower than most comparable units, making efficient use of tank
supply
• Works with disposable ENDO SMARTCAP® and ENDOGATOR® hybrid tubing for safety and
compliance
Safety Features
•
Dual inline pressure regulators ensure a constant pressure
•
Additional mechanical pressure relief at ≤12 PSI prevents overpressure
•
Low CO
2
input pressure is indicated by a yellow light on the front panel
•
On initial power up, gas flow is off until the flow knob is turned on
•
CO
2
warmer will not operate unless flow is initiated
Theory of Operation
The ENDO STRATUS CO
2
insufflator works by regulating CO
2
from a tank source to a preset pressure and
then controlling the output of CO
2
to an GI endoscope system for ultimate delivery as a distention media in the
gastrointestinal tract. The clinician will use the air/water valve on the GI endoscope and visual feedback of the
GI endoscopic system to manually distend the gastrointestinal tract with CO
2.
The ENDO STRATUS CO
2
insufflator contains a CO
2
warming feature that allows the clinician to modulate and
control delivery of CO
2
to the patient that has been warmed to a target temperature of 37°C with an upper tol-
erance of +3°C. Warming is achieved as CO
2
flows across a heating element which can be switched on or off
by the user, depending on if warming of the CO
2
is desired. The heating of the CO
2
is accomplished through
an internal 20W heating element with dual redundant temperature sensors.
The flow rate can be adjusted to low, medium or high settings depending on the desired rate of insufflation,
with flow rates of 1.4 L/min, 2.4 L/min and 3.5 L/min maximum, respectively.
When the unit is turned on, the CO
2
flow and heating function are off by default. To initiate gas flow the user
must turn the flow setting knob from the “off” position. The unit will detect gas flow and will not allow the heater
to operate unless gas flow is detected. In addition, there is a low gas pressure sensor and the unit will indicate
when the input CO
2
pressure reaches 25PSI by illuminating a yellow light on the front panel.
The unit also has an output to power the water bottle warmer. The water bottle heating element maintains the
temperature of the water in a sterile water bottle at 37±3°C. It is controlled by dual temperature sensors for
redundancy and safety.
