Signal Words The following signal words are used throughout this manual: DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices or potential equipment damage.
NOTE
Indicates additional helpful information.
Dangers, Warnings and Cautions Follow the dangers, warnings and cautions described below when handling this instrument. This information is supplemented by the dangers, warnings and cautions described in each chapter. DANGER
S The UHI-2 is not explosion-proof. Never install or operate it in the presence of flammable gases. S Supply medical grade CO2 gas only. Never use other kinds of gas. Using gases other than CO2 gas may result in fire, poisoning, complications, etc. Use the hose for cylinder or Adaptor for Medical Gas Pipeline as listed in this instruction manual to connect the CO2 gas cylinder or Medical Gas Pipeline.
WARNING
S Position the patient port of the insufflator and as much of the associated tubing as is practical above the insufflation site, so that any patient fluids inadvertently entering the tubing do not drain back into the insufflator under gravity. S Always keep the gas cylinder in the upright position. Fasten the cylinder to prevent it from toppling. If the gas cylinder is placed horizontally or in an inclined position, liquefied CO2 may be transmitted into the insufflation channel inside the UHI-2 and normal insufflation may become impossible.

HIGH FLOW INSUFFLATION UNIT UHI-2
Important Information--Please Read Before Use
S To prevent gas embolism caused by intra-abdominal over-pressurization from the combined use of an insufflator and a laser device, argon-enhanced coagulator, or other gas supply devices, carefully read and understand the following before using. -- In the event of combined use of an insufflator and a laser device, argon-enhanced coagulator or other gas supply devices, when performing laparoscopy, both instruments become a source of supply for gas. Accordingly, the determined amount of pressure in the abdomen is reached in a shorter time than when solely using the pneumoperitoneurn device. Be careful that the intra-abdomen does not become over-pressurized. The laser device argon-enhanced coagulator, and other gas supply devices are not equipped with functions to monitor the abdominal pressure (automatic termination of insufflation, warning light or alarm). Although the insufflator is equipped with these functions, it does not always prevent gas embolism inasmuch as this depends on the patient and the condition of the infected area. We ask that the physicians make a suitable judgment from a professional standpoint. -- If the insufflator emits a warning (warning light or alarm) for intra-abdominal over-pressurization, quickly open the stopcock or valve of the trocar. In this event, reduce the amount of outflow from the laser device, argon-enhanced coagulator, or other gas supply device. If use is continued while the alarm is sounding, there is a risk of gas embolism due to intra-abdominal over-pressurization. S When Relief Mode is set to ON, the intra-abdominal gas will flow backward into the equipment for relief through the built-in valve into the equipment. To prevent the internal surfaces of the equipment from being contaminated, be sure to use a Disposable Filter. When no filter is used, make sure Relief Mode is set to OFF.

Important Information--Please Read Before Use
S Use the Disposable Filter when the Relief Mode is activated to prevent cross-contamination from the backflow of body fluids (e.g. blood). Olympus recommends using filter TYPE PALL ORO1H (0.2 µm, hydrophobic), or contact Olympus for further details. Olympus highly recommends using a Disposable Filter when the Relief Mode is not activated. S To reduce the risk of electric shock, do not remove cover. S To prevent operator shock and instrument damage, keep liquids away from all electrical equipment. If fluid enters the UHI-2, stop operation immediately and contact Olympus. S The UHI-2 is for use in medical facilities under the supervision of a trained physician. Do not use under any other conditions. S Always use the UHI-2 as outlined in this instruction manual. Improper use will not only impair functions and prevent optimum performance, but may cause equipment damage and/or complications. Before each use, always inspect the equipment as outlined in this instruction manual. S To prevent electrical shock hazards, the housing of the UHI-2 must be grounded. Always connect the power cord plug to a properly grounded hospital grade AC outlet (wall mains outlet). Properly grounded Wall Mains Outlet
Power Plug
S Prepare spare CO2 gas cylinders for quick replacement if the cylinder used during the procedure should run out. S To ensure that the operation can be completed without complication in the case of a malfunction, prepare a spare UHI-2 unit as a backup.

HIGH FLOW INSUFFLATION UNIT UHI-2
Important Information--Please Read Before Use
S During use, especially when a high gas flow rate is selected, a large volume of CO2 gas will be used. To prevent an oxygen deficiency in the operating room, ensure that the operating room is properly ventilated. S Only use the UHI-2 as described in “Operating Environment” in “Specifications” contained in “Appendix”. Use under other conditions may not only impair normal performance, but may also result in equipment breakdown. S If a filter is not used and fluid (e.g. blood) flows back into the insufflation tube, make sure that it does not enter the UHI-2. Should any fluids enter the UHI-2, immediately terminate its use and contact Olympus. S To avoid complications, monitoring of the patient’s parameters such as endotidal CO2, electrocardiogram, body temperature, etc., during use of UHI-2. And take appropriate measures. S Metabolic Acidosis and Resultant Cardiac Irregularity. Prolonged intra-abdominal pressures greater than 20 mmHg should be avoided. This can cause any of the following: -- Decreased respiration with compromised diaphragmatic excursion -- Decreased venous return -- Decreased cardiac output -- Acidosis S Excessive flow rates and/or excessive pressures may result in an excessive absorption of CO 2 and/or gas embolism. The abdomen can be adequately distended by maximum pressure of 20 mmHg. It is seldom necessary to use an abdominal pressure greater than 20 mmHg. Little intravasation or tubal passage should occur at these levels. Pressures over 20 mmHg are rarely necessary and will increase the amount and the rapidity of intravasation and tubal passage of gas. Adequate respirations helps avoid problems related to CO2. S Idiosyncratic reactions. Patients with sickle cell disease or pulmonary insufficiency may have an increased risks of metabolic imbalance related to excessive CO2 absorption.

Important Information--Please Read Before Use
S Other possible complications include CO2 embolization, hypothermia, and carbonic acid irritation of the diaphragm. Direct access of insufflated CO2 gas to the vascular system (e.g. through an open vessel in the intra-abdominal cavity, or an improperly inserted Veress needle) may result in gas embolism. S Use of this device for intra-abdominal distention is contraindicated whenever laparoscopy is contraindicated. S This device is contraindicated for hysteroscopic insufflation, i.e., it must not be used for intrauterine distention. CAUTION
S This instrument contains no user serviceable parts. Repairs should be performed only by Olympus. S Before using a Veress needle and trocar, inspect the items as outlined in Section 4.6, “Inspection of UHI-2 Operation When Using a Veress Needle/Trocar”.
NOTE
As defined by the international safety standard (IEC60601-1), medical electrical equipment is classified into the following types: Type CF applied part (the instrument can safely be applied to any part of the body, including the heart), and Type B/BF applied part (the instrument can safely be applied to any organ except the heart). Which part of the body the endoscope or accessories can safely be applied to depends on the classification of the equipment to which the instruments are connected. Before beginning the procedure, review the current leakage classification type of each instrument that you will use for the procedure. Classification types are clearly specified on the instruments and in the instruments’ instruction manuals. Symbol
