MN1-6015 Rev. 6 2. Precautions for cleaning, disinfection and sterilization The following warnings and cautions must be observed when cleaning, disinfecting and sterilizing the probe and accessories.
Warning Wear protective gloves and other protective gear during cleaning, disinfection and sterilization. Handling of the probe with your bare hands before sterilization can result in an infection. After finishing soaking the probe in cleaning agents, thoroughly wash it with running water. Residual cleaning agents can cause an adverse reaction to the operator or the patient. After chemical sterilization, thoroughly wash the probe with sterile water. Residual chemicals can cause an adverse reaction to the operator or patient. (USA only) After soaking in a disinfectant, throughly wash the equipment with deionized water. Leavings of the disinfectant can cause an adverse reaction on the bodies of the operator or patient. Perform full aeration after gas sterilization. Residual gas can cause an adverse reaction to the operator or patient. Do not clean or sterilize using procedures other than those specified in this manual. Failure to clean and sterilize the equipment can result in an infection. It can also result in damage to the probe or reduced performance. The probe is not compatible with autoclave sterilization or boiling and other types of sterilization at temperatures exceeding 60°C [140°F]. For details on the usage conditions of chemicals and sterilization procedures, refer to the documentation supplied with the respective chemical or sterilization equipment. Infection can be resulted due to incomplete sterilization. Wrong sterilization procedure could cause deterioration of the probe.
Caution Do not immerse the probe into any liquid beyond the range of IPX7. The range is indicated in the separate instruction manual “Specification”. If any liquid enters the connector, immediately stop using the probe and contact one of our offices and/ or distributor’s offices listed on the back cover. Liquid in the connector could cause electric shock to the operator or patient. Do not wipe the ultrasonic radiation part with alcohol. Alcohol could damage the part. Do not use organic solvent such as thinner for cleaning to prevent the probe from damage. Do not use hard or sharp objects to remove residue on the probe. Such objects may damage the probe. If it is necessary to use a waterproof case, obey the instruction manual of waterproof case regarding fitting to the probe. Additional information: The Instructions provided above have been validated by the medical device manufacturer as being CAPABLE of preparing a medical device for re-use. It remains the responsibility of the processor to ensure that the processing as actually performed using equipment, material and personnel in the processing facility achieve the desired result. This requires validation and routine monitoring of the process. Likewise any deviation by the processor from the instructions provided should be properly evaluated for effectiveness and potential adverse consequences. -3DM# 124192 V6

MN1-6015 Rev. 6 3. Reprocessing instruction according to ISO 17664 The probe and accessory must be reprocessed after each use. Refer to the reprocessing instruction in this chapter. Table 2 WARNINGS
・The probe is delivered unsterile. Prior to the first use, reprocess the probe. ・Temperature should not exceed 60°C[140°F] during reprocessing. ・Probe connector has no water resistance.
Limitations on reprocessing
The probe is not completely submergible (Do not immerse the probe into any liquid beyond the range of IPX7. The range is indicated in the separate instruction manual “Specification”.) Parts which are not submergible can only be disinfected by wipe disinfection.
Transportation before using
The probe should be packed in a sterile pouch or container to transport from Central Sterile Supply Department (CSSD) to an operating room. Be careful not to damage the sterile pouch or container during transportation.
The level of processing required depends on the type of equipment and its use. The CDC (Centers for Disease Control and Prevention) in the USA and the RKI (Robert Koch Institute) in Germany classify medical devices according to their use. For each classification, they specify the level of disinfection/ sterilization processing that is required before use. Table 3 summarizes this information. Table 3 Classification
Definition
Processing
Noncritical
Application part only contacts intact and uninjured skin
Cleaning ↓ Disinfection [in the USA, low-level disinfection]
Application part contacts mucosa (intracavitary application)
Cleaning ↓ Disinfection (Disinfectant with bactericidal, fungicidal and virucidal effect) [in the USA, high-level disinfection or sterilization]
Semicritical
Critical
Application part contacts intracorporeal tissue directly (intraoperative application)
Cleaning ↓ Disinfection ↓ Sterilization *1
*1. When sterilization is not possible, the FDA in the USA recognize that disinfection (in the USA, high-level disinfection) and the use of a sterile gel and sterile transducer cover, as described in the instructions provided with the transducer cover, is an accepted method of infection control for probe.
