Chapter 3 Installation and Connection Remove the dust cap and plug from both ends of the cylinder hose for UHI-3 (MAJ-1080 only). Inspect the cylinder hose for UHI-3 for damage, cracks and other irregularities. Use the supplied wrench to attach the cylinder hose to the gas inlet on the rear panel of the UHI-3.
(MAJ-1084/1085) Using gases other than medical grade CO may result in fire, poisoning, complications, etc. In addition, oil, impurities, etc., may penetrate into the interior of the UHI-3 and impede proper CO gas insufflation. • Connect the gas supply hose to the UHI-3 before connecting it to the CO gas connector.
Use the supplied wrench to attach the medical gas pipeline adaptor for UHI-3 to the CO gas inlet on the rear panel of the UHI-3. Tighten with a force of 24.5 N⋅m (2.5 kgf⋅m) (see Figure 3.2). Connect the adaptor to the hose for medical gas pipeline (see Figure 3.4).
The type of filter is PALL OR01H (0.2 μm, hydrophobic) or equivalent filters; contact Olympus for further details. Even if the relief mode is not activated, Olympus highly recommends the use of a disposable filter.

Insert the suction tube’s small diameter tube all the way into the groove of the CO suction control pinch valve on the front panel of the UHI-3 (see Figure 3.10). To prevent the tube from collapsing, there must be at least 10 cm between the differential diameter connector and the pinch valve groove (see Figure 3.11).
(endoscope, light source, ancillary equipment, etc.). Attach the connectors of the aeration cable (MAJ-877) to the system connector of the UHI-3 and the system connector of the UES-40 or the system-A connector of the SonoSurg-G2. Then tighten the fixing screws on both connectors (see Figure 3.12).

Before using this instrument for the first time, reprocess it according to the instructions given in Chapter 6, “Care, Storage and Disposal”. Inspection of the UHI-3 main unit Power supply Press the POWER switch to turn the unit ON. Confirm that all indicator lamps light and three tones sound.
Page 40
If the indicator drops down, gas is leaking. Check the connection of the cylinder hose again. If the indicator continues to move down, terminate operation and immediately contact Olympus. While the gas cylinder valve remains closed, set the insufflation mode to HIGH and press the START switch.
Page 41
If the tube obstruction alarm does not sound, or if the excessive pressure alarm sounds, immediately stop using the insufflator and contact Olympus. Press the stop switch. Reset inspection Set the insufflation mode to LOW.
Chapter 4 Inspection Inspection of the cylinder hose for UHI-3 If the cylinder hose for UHI-3 is damaged, replace it with a new one. Inspect the cylinder hose for UHI-3 for scratches, cracks, or other damage. Inspect the packing inside the yoke for scratches, cracks or other damage.
(e.g. blood) when the relief mode is activated, a disposable filter is necessary. The type of filter is PALL OR01H (0.2 μm, hydrophobic) or equivalent filters; contact Olympus for further details. Even if the relief mode is not activated, Olympus highly recommends the use of a disposable filter.
If the tube obstruction alarm or the excessive pressure alarm sounds, or if the abdominal pressure indication increases, the veress needle or trocar is damaged or not compatible with the UHI-3. Do not use incompatible veress needles or trocars. •...
• If the UHI-3 unit is set to “insufflation” for a prolonged period of time without a CO insufflation connection, the decompressing devices may freeze. Under these conditions, operation of the UHI-3 unit, including insufflation, may be impossible.
Chapter 5 Operation • Should blood, etc., back flow into the insufflation tube, make sure that it does not enter the UHI-3. Should any body fluids enter the UHI-3, immediately terminate its use and contact Olympus. • When a filter is used with the device, backward flow of body fluids (e.g.

Chapter 5 Operation To keep insufflation safer, the UHI-3 controls the gas flow during the first 25 seconds after the flow starts. Therefore, the actual flow rate of the gas might not reach the maximum flow rate for up to 25 seconds.

Connect the suction tube as outlined in Section 3.6, “Connecting the insufflation tube and suction tube”. Insert the connector of the foot switch (MH-317) into the foot switch connector on the UHI-3’s rear panel until a click is heard (see Figure 5.3). To disconnect, push this button while pulling outward.
After the pedal is released, the exhaust function continues operating for about 5 seconds. When the UHI-3 is set to stop mode, its flow setting is LOW or abdominal pressure is below 3 mmHg, this function is disabled.
Close the gas cylinder valve (see Figure 5.4). Figure 5.4 Set the UHI-3 to insufflation mode and perform insufflation. After the UHI-3 enters the stop mode, turn the power switch OFF. Disconnect all tubes and the CO gas cylinder. Disconnect the power cord plug from the hospital grade AC outlet (wall mains outlet).
