Important Information - Please Read Before Use

 Use in combination with the lens cleaning sheath WARNING • Anytime you observe an irregularity in the endoscopic CO2 regulation unit, immediately stop using the endoscopic CO2 regulation unit and withdraw the endoscope from the patient slowly as described in the instruction manual for the lens cleaning sheath. • To prevent gas embolism caused by intra-abdominal over-pressurization from the combined use of the lens cleaning sheath and a laser device, argon-enhanced coagulator, or other gas supply devices, carefully read and understand the following before using in case the insufflator is used in operation: − When performing endoscopic operation using a lens cleaning sheath and a laser device, argon-enhanced coagulator, or other gas supply devices simultaneously, both instruments become a source of supply for gas. Accordingly, the desired pressure in the abdomen is reached in a shorter time than when a lens cleaning sheath is used alone. In these cases, be careful that the cavity does not become over-pressurized. The laser device, argon-enhanced coagulator, and other gas supply devices are not equipped to monitor the cavity 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 himself. − If the insufflator emits a caution (caution light or alarm) for cavity over-pressurization, quickly open the stopcock or valve of the trocar. Then, reduce the amount of outflow from the laser device, argon-enhanced coagulator, or other gas supply device. If use is continued while the alarm sounds, there is a risk of gas embolism due to cavity over-pressurization. • Be careful not to feed CO2 too much during CO2 gas feed or spraying. Excessive CO2 gas feed/spraying may cause pain to the patient and/or gas embolism. Reduce the use of CO2 gas feed and spraying at the requisite minimum level. • In case the insufflator is used in operation, open the trocar cannula stopcock if the pressure in the abdomen exceeds the set pressure by more than 5 mmHg. • Do not attempt to insufflate the abdominal cavity using the lens cleaning sheath. Otherwise, patient injury and/or gas embolism may result. • Do not use the endoscopic CO2 regulation unit in combination with other than the compatible lens cleaning sheath (with the MAJ-1345, MAJ-1537, or MAJ-659, for example). Otherwise, CO2 gas is fed continuously and patient pain and gas embolism can result.
