Probe Cleaning and Disinfection Instructions Probe Safety WARNING

Ultrasound probes are highly sensitive medical instruments that can easily be damaged by improper handling. Use care when handling and protect from damage when not in use. DO NOT use a damaged or defective probe. Failure to follow these precautions can result in serious injury and equipment damage. Ultrasound transducers can easily be damaged by improper handling and by contact with certain chemicals. Failure to follow these precautions can result in serious injury and equipment damage. • Do not immerse the probe into any liquid beyond the level specified for that probe. Never immerse the transducer connector or probe adapters into any liquid. • Avoid mechanical shock or impact to the transducer and do not apply excessive bending or pulling force to the cable. • Transducer damage can result from contact with inappropriate coupling or cleaning agents: • Do not soak or saturate transducers with solutions containing alcohol, bleach, ammonium chloride compounds or hydrogen peroxide • Avoid contact with solutions or coupling gels containing mineral oil or lanolin • Avoid temperatures above 60°C. • Inspect the probe prior to use for damage or degeneration to the housing, strain relief, lens and seal. Do not use a damaged or defective probe.

Biological Hazard CAUTION

Adequate cleaning and disinfection are necessary to prevent disease transmission. It is the responsibility of the equipment user to verify and maintain the effectiveness of the infection control procedures in use. Always use sterile, legally marketed probe sheaths for intra-cavitary and intra-operative procedures. For neurological intra-operative procedures, use of a legally marketed, sterile, pyrogen free probe sheath is REQUIRED. Probes for neuro surgical use must not be sterilized with liquid chemical sterilants because of the possibility of neuro toxic residues remaining on the probe. A defective probe or excessive force can cause patient injury or probe damage: • Observe depth markings and do not apply excessive force when inserting or manipulating intercavity probes. • Inspect probes for sharp edges or rough surfaces that could injure sensitive tissue. In order for liquid chemical germicides to be effective, all visible residue must be removed during the cleaning process. Thoroughly clean the probe, as described on the following page before attempting disinfection. CREUTZFIELD-JACOB DISEASE Neurological use on patients with this disease must be avoided. If a probe becomes contaminated, there is no adequate disinfecting means.

Electrical Hazard

The probe is driven with electrical energy that can injure the patient or user if live internal parts are contacted by conductive solution: • DO NOT immerse the probe into any liquid beyond the level indicated by the immersion level diagram. Never immerse the probe connector or probe adaptors into any liquid. • DO NOT drop the probes or subject them to other types of mechanical shock or impact. Degraded performance or damage such as cracks or chips in the housing may result. • Inspect the probe before and after each use for damage or degradation to the housing, strain relief, lens, and seal. A thorough inspection should be conducted during the cleaning process. • DO NOT kink, tightly coil, or apply excessive force on the probe cable. Insulation failure may result. • Electrical leakage checks should be performed on a routine basis by GE Service or qualified hospital personnel. Refer to the service manual for leakage check procedures.

Using Probes

LOGIQ 3 Expert/LOGIQ 3 Pro/LOGIQ 3 Quick Guide Probe Cleaning, After Each Use

Direction 5122541-100 Rev. 4

Probe Immersion Levels

1. Disconnect probe from ultrasound console and remove all coupling gel from probe by wiping with a soft cloth and rinsing with flowing water.

16 Probe Disinfection Agents Ultrasound probes can be disinfected using liquid chemical germicides. The level of disinfection is directly related to the duration of contact with the germicide. Increased contact time produces a higher level of disinfection.

2. Wash the probe with mild soap in lukewarm water. Scrub the probe as needed using a soft sponge, gauze, or cloth to remove all visible residue from the probe surface. Prolonged soaking or scrubbing with a soft bristle brush (such as a toothbrush) may be necessary if material has dried onto the probe surface.

The following high level disinfectant agents have been approved for use with all probes: • Cidex OPA • Cidex

3. Rinse the probe with enough clean potable water to remove all visible soap residue.

Cidex Plus has been approved for the 8C, 4DE7C, and 4D3C-L probes.

4. Air dry or dry with a soft cloth.

Sporox II high level disinfectant has been approved for the 7L, 10L, 12L, 4S, 8C, E8C, and P8D probes.

Probe Disinfection, After Each Use

Pera Safe high level disinfectant has been approved for the 7L, 10L, 12L, M7C, M12L, E8C, 4DE7C, 4D3C-L, and 4D10L probes.

1. Prepare the germicide solution according to the manufacturer's instructions. Be sure to follow all precautions for storage, use and disposal.

The following low level disinfect agents have been approved for use with all probes:

2. Place the cleaned and dried probe in contact with the germicide for the time specified by the germicide manufacturer. High-level disinfection is recommended for surface probes and is required for endocavitary and intraoperative probes (follow the germicide manufacturer's recommended time). Probes for neuro surgical intra-operative use must NOT be sterilized with liquid chemical sterilants because of the possibility of neuro toxic residues remaining on the probe. Neurological procedures must be done with the use of legally marketed, sterile, pyrogen free probe sheaths. 3. After removing from the germicide, rinse the probe following the germicide manufacturer's rinsing instructions. Flush all visible germicide residue from the probe and allow to air dry.
