Sterilization Sterilization issues are confined to the AccuPach VI probe that comes in contact with the patient’s eye. In order to prevent the transmission of disease, medical authority(ies) having jurisdiction guidelines are referenced for proper control of sterilization issues. These guidelines are frequently updated so be sure to contact your local disease control officer for the latest information and sterilization techniques. The probe tip should be sterilized or disinfected before use on each patient. The recommended sterilization technique is to immerse the probe tip (and only the probe tip) in an antibacterial solution. Follow the manufacturer’s written protocol when using any antibacterial solution.
Disinfection and Cleaning Disinfection issues are confined to the AccuPach VI probe that comes in contact with the patient’s eye and to the test block. In order to prevent the transmission of disease, medical authority(ies) having jurisdiction guidelines are referenced for proper control of sterilization issues. These guidelines are frequently updated so be sure to contact your local disease control officer for the latest information and disinfection techniques. The probe tip should be sterilized or disinfected before use on each patient. The test block should be disinfected after each use. The recommended disinfection technique is to gently wipe the probe tip or the test block with isopropyl alcohol (and no other substance). It is imperative that the alcohol be given time to evaporate before applying a probe to the patient’s eye.

Safety Precautions
Electrical Hazard and Safety The instrument, foot switch and probe of the AccuPach VI are electrical/electronic devices. Reasonable care should be taken when making electrical connection and handling electrically powered devices. Avoid the use of damaged electrical equipment or frayed electrical cords. If repair or maintenance is to be performed on the AccuPach VI, the equipment must be turned off and the power cord disconnected. Do not use probes or foot switches that have frayed or damaged connection cables. The device covers must not be removed except by qualified personnel. There are no user controls inside the unit. To avoid injury, do not operate the AccuPach VI without protective covers. The system is intended to operate from a power source of 100 - 240 VAC, 47 - 63 Hz. Protective earth grounding through the grounding connection in the power cord is essential for safe system operation. Use only a hospital-grade power cord and the connectors supplied with the AccuPach VI. Also, be sure the power cord and connector are in good condition.

Avoiding Equipment Damage The only peripheral equipment that may be connected to an AccuPach VI is a printer that has been selected and installed in compliance with EN60601-1 requirements. The AccuPach VI provides no explosion protection from static discharge or arcing components. Do not operate the instrument in the presence of explosive gases such as flammable mixtures of anesthetic and air, or nitrous oxide.
ALARA Principle This instrument has no user operated controls or settings that affect the acoustic output. When using the device, the ALARA (As Low As Reasonably Achievable) principle should be followed. This principle is used to reduce unnecessary, potentially hazardous exposure to individuals, by keeping doses and test repetition As Low As Reasonably Achievable to achieve the required diagnostic information.
