Using Probes Connecting a probe

Activating the probe

1. Place the probe's carrying case on a stable surface and open the case.

Select the appropriate probe from the probe indicators on the Touch Panel.

2. Carefully remove the probe and unwrap the probe cable.

The probe activates in the currently-selected operating mode. The probe's default settings for the mode and selected exam are used automatically.

3. DO NOT allow the probe head to hang free. Impact to the probe head could result in irreparable damage. 4. Turn the connector locking handle clockwise. 5. Align the connector with the probe port and carefully push into place. 6. Turn the connector locking handle clockwise to secure the probe connector. 7. Carefully position the probe cable in the probe cord holder spot so it is free to move, but not resting on the floor.

Ensure that the probe is placed gently in the probe holder.

Disconnecting the probe Probes can be disconnected at any time. However, the probe should not be selected as the active probe.

Deactivating the probe

1. Move the probe locking handle counterclockwise. Pull the probe and connector straight out of the probe port.

When deactivating the probe, the probe is automatically placed in standby mode.

2. Carefully slide the probe and connector away from the probe port and around the right side of the keyboard. Ensure the cable is free.

1. Press the Freeze key. 2. Gently wipe the excess gel from the face of the probe.

3. Be sure that the probe head is clean before placing the probe in its storage box.

3. Carefully slide the probe around the right side of the keyboard, toward the probe holder. Table 1-1: Probe Indications for Use

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

Using Probes

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.

LOGIQ 7 Quick Guide Probe Cleaning, After Each Use 1. Disconnect probe from ultrasound console and remove all coupling gel from probe by wiping with a soft cloth and rinsing with flowing water. 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.

Probe Disinfection, After Each Use

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.

•
