CO2EFFICIENT ENDOSCOPIC INSUFFLATOR Operator’s Manual
Section 2.0 INTRODUCTION This manual provides information for the operation of the CO2EFFICIENT ENDOSCOPIC INSUFFLATOR, (also referred to in this manual as "unit" or "device"). DEFINITIONS The following list is abbreviations of commonly used terms throughout this manual: LPM
Liter Per Minute (or Liters Per Minute)
mm Hg
millimeters of Mercury
gas
CO2
hPa
Hundred Pascal
2.1 INDICATION AND CONTRAINDICATIONS Indications for Use: The CO2EFFICIENT ENDOSCOPIC INSUFFLATOR is designed to use CO2 as a distention media in the gastrointestinal tract when used in conjunction with a gastrointestinal endoscope. Contraindications for Use: The CO2EFFICIENT ENDOSCOPIC INSUFFLATOR should be used only for an endoscopic procedure when insufflation of the gastrointestinal tract is necessary to support navigation of the endoscope and perform any evaluation procedures through the endoscope, and should therefore not be used for any other treatments. It should only be used under the direct guidance of a physician experienced in Gastrointestinal Endoscopy procedures. This device is contraindicated for hysteroscopic or laparoscopic insufflation, i.e., it must not be used for intrauterine distension. This device is contraindicated for CT Colonography.
2.2 SAFETY FEATURES The following features help to ensure safe operation of the machine: FLOW STOP/RUN button: Upon turning power on, gas flow is not initiated until the FLOW STOP/RUN button is pressed. An initial pressure relief will occur at 375 mm Hg and a redundant pressure relief will occur at 400 mm Hg. An audible alert will sound when the CO2 gas supply tank pressure is low. An audible alert (a single chirp) will sound when the flow of CO2 is automatically stopped by the device.
CO2EFFICIENT ENDOSCOPIC INSUFFLATOR Operator’s Manual
Page 4
Section 3.0 THEORY OF OPERATION The CO2EFFICIENT ENDOSCOPIC INSUFFLATOR operates by administering CO2 at a maximum flow rate of 3 LPM, and then monitoring the endoscopic pressure. A mode of operation is selected by the operator, by using a switch found on the front panel to select from Free Flow Mode and Managed Flow Mode. It is used to change the rate that the flow is delivered to the endoscopic system. When the switch is set to Free Flow Mode, the unit will deliver CO2 at a flow rate of 3 liters per minute continuous. The clinician will use the air/water valve on the endoscope and visual feedback of the endoscopic system to manually distend the gastrointestinal tract with CO2. When the switch is set to Managed Flow Mode, the system will be delivering CO2 in a more efficient manner. This mode reduces the amount of CO2 that is lost through the air/water valve which is normally lost at a rate of 3 liters per minute. When gas is not used in the endoscopic system to insufflate, the unit will operate at the Managed Flow rate of 0.25 to 1.0 liter per minute. This transition to the Managed Flow rate will occur if the unit senses no need for insufflation in a 2 second time period. When gas is needed to insufflate, the unit will deliver CO2 at a flow rate of 3 liters per minute. The user will need to place the system into RUN mode in order for it to deliver the CO2 to the endoscopic system. The CO2EFFICIENT ENDOSCOPIC INSUFFLATOR has a Pressure Relief Valve set at 375 mm Hg and an independent redundant Pressure Relief Valve pre-set to 400 mm Hg. Both pressure relief safety devices are active whether the FLOW STOP/RUN is on or off.

Section 6.0 FRONT PANEL CONTROLS
NOTE: The appearance of your CO2EFFICIENT ENDOSCOPIC INSUFFLATOR may differ slightly from the units shown in the illustrations and photographs. (Example: buttons may be round or square). [1] GAS SUPPLY INDICATOR Three colors of LED’s to indicate the relative amount of gas available in a “D” or “E” CO2 supply tank. [2] VOLUME LITERS DISPLAY Indicates the total amount of gas used since last reset. [3] VOLUME RESET Clears the volume display to zero. [4] FLOW STOP/RUN Depression starts flow and button will illuminate. CO2 will flow in one of two modes set by the switch. The pressure response characteristics at which CO2 is delivered to distend the gastrointestinal tract is a function of the clinician and how this clinician uses CO2 to distend the gastrointestinal tract during a procedure. In Managed Flow Mode, the control system will automatically transition between the high flow rate and low flow rate as required during the procedure to compensate for external variables. To prevent wasting gas in the Free Flow mode, when the FLOW STOP/RUN button is pressed initially and after 150 Liters of CO2 is continuously delivered, the unit automatically returns to STOP mode. An audible alert, in the form of a single chirp, will sound when the unit automatically returns to STOP mode. Thereafter, subsequent presses of the FLOW STOP/RUN button will resume the CO2EFFICIENT ENDOSCOPIC INSUFFLATOR Operator’s Manual
Page 10
delivery of CO2 for an additional 150 Liters before automatically returning to STOP mode. To prevent wasting gas in the Managed Flow mode, when the FLOW STOP/RUN button is pressed initially and no changes in pressure have been detected for 10 minutes, the unit automatically returns to STOP mode. An audible alert, in the form of a single chirp, will sound when the unit automatically returns to STOP mode. However, you can stop the flow using the FLOW STOP/RUN button while the unit is in RUN mode, as evidenced by the illuminated FLOW STOP/RUN button. The user can always depress the FLOW STOP/RUN button during any of these volume increments to stop delivery of CO2.
NOTE: Flow cannot be initiated if gas bottle pressure is less than 25 psi.
[5] FLOW MODE SELECTION SWITCH The unit operates in one of two modes. When the switch is set Free Flow Mode, the unit will deliver CO2 at a flow rate of 3 liters per minute continuous. The clinician will use the air/water valve on the endoscope and visual feedback of the endoscopic system to manually distend the gastrointestinal tract with CO2. When the switch is set to Managed Flow Mode, the system will be delivering CO2 in an more efficient manner. This mode reduces the amount of CO2 that is lost through the air/water valve which is normally lost at a rate of 3 liters per minute. When gas is not used in the endoscopic system to insufflate, the unit will operate at the Managed Flow rate of 0.25 to 1.0 liter per minute. This transition to the Managed Flow rate will occur if the unit senses no need for insufflation in a 2 second time period. When gas is needed to insufflate, the unit will deliver CO2 at a flow rate of 3 liters per minute. [6] GAS OUTPUT CONNECTION TO ENDOSCOPE Connector for Tubing Set.
