Disinfecting Transducers with Wipes and Sprays
To disinfect transducers, you can use either an immersion method or a wipe method with a disinfectant recommended by Philips Ultrasound. Use the method that is biologically appropriate, as described in Choosing a Disinfectant.
This section provides instructions on using the wipe or spray method. For information on the immersion method, see Disinfecting Transducers by Immersion (High-Level Disinfection).
To use the wipe or spray method to disinfect transducers
Transducers can be disinfected using the wipe method only if the product labeling of the compatible disinfectant you are using indicates it can be used with a wipe method.
WARNING: Always use protective eyewear and gloves when cleaning and disinfecting any equipment.
1. After cleaning the transducer and cable, wipe or spray the transducer and cable with a low- and intermediate-level disinfectant. Allow for the manufacturer's recommended contact time. For a list of compatible disinfectants, use the Find Compatible Disinfectants search tool.
2. Remove any residue with a water-moistened soft cloth. Do not allow any solutions to air dry on the transducer.
3. Examine the device and cable for damage such as cracks, splitting, sharp edges, or projections. If damage is evident, discontinue use of the device and contact your Philips Ultrasound representative.
Caution: The use of 70% isopropyl alcohol (rubbing alcohol) on transducers is restricted. Wipe only the distal tip of the transducer up to 2.5 cm (1 in) from the strain relief/housing joint with an isopropyl alcohol solution. Do not wipe the strain relief/housing joint, the strain relief, or the cable with isopropyl alcohol (see figure 1).
Figure 1: Restricted use of alcohol.
Isopropyl alcohol can cause damage to these parts of the transducer. This damage is not covered by the warranty or your service contract.

Cleaning and Disinfecting Cables and Connectors with Wipes and Sprays
Use this method to disinfect the cables and connectors for all transducers that can be disinfected using a recommended wipe or spray disinfectant.
WARNING: Always use protective eyewear and gloves when cleaning and disinfecting any equipment.
Caution: Attempting to disinfect a cable or connector by using a method other than the one included here can damage the device and will void the warranty. Orient the parts that must remain dry higher than the wet parts until all parts are dry.
To clean and disinfect cables and connectors
1. Disconnect the device from the system.
2. Orient the device and the connector so they are both facing up (see figure 2).
Figure 2: Disinfecting Cables
Cautions:
3. Use a soft cloth lightly dampened in a mild soap or detergent solution to clean the cable and the connector. A soft-bristled brush can be used to clean only the metal surfaces of the connector. Do not allow any type of fluid to enter the device. Be careful that fluid does not enter through the strain relief, through the connector, through the electrical contacts, or through the areas surrounding the locking lever shaft and the strain relief.
WARNING: If a premixed solution is used, be sure to observe the solution expiration date.
Cautions:
You can use an alcohol solution for disinfection on the connector only. Ensure the solution is only 70% alcohol or less. Solutions of more than 70% alcohol can cause product damage (see Restricted Use of Isopropyl Alcohol to Clean Transducers).
Do not use any alcohol or alcohol-based products on the cable.
Avoid disinfectant contact with the connector label.
4. Mix the disinfection solution compatible with your cable (use the Find Compatible Disinfectants search tool to find compatible disinfection solutions) according to label instructions for solution strength.
5. Wipe or spray the cable and connector with the disinfectant, following disinfectant label instructions for wipe durations, solution strengths, and duration of disinfectant contact with the cable.
Note: Ensure that the solution strength and duration of contact are appropriate for the intended clinical use of the device. Ensure that the disinfectant solution does not enter the device or the connector or come into contact with the connector label.
6. Air dry or towel dry with a sterile cloth according to the instructions on the disinfectant label.
7. Examine the device and cable for damage such as cracks, splitting, sharp edges, or projections. If damage is evident, discontinue use of the device and contact your Philips Ultrasound representative.
