Probe Overview LOGIQ 5 Basic User Manual 17-19 Direction 2300002-100 Rev. 2 Disinfecting probes (continued) 1. Prepare the germicide solution according to the manufacturers instructions. Be sure to follow all precautions for storage, use and disposal. 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 manufacturers 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 manufacturers rinsing instructions. Flush all visible germicide residue from the probe and allow to air dry. CAUTIONCREUTZFIELD-JACOB DISEASE Neurological use on patients with this disease must be avoided. If a probe becomes contaminated, there is no adequate disinfecting means. Biological Hazard
Probes and Biopsy 17-20 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Disinfecting probes (continued) WARNINGUltrasound 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.
Probe Overview LOGIQ 5 Basic User Manual 17-21 Direction 2300002-100 Rev. 2 Coupling gels ApplyingIn order to assure optimal transmission of energy between the patient and probe, a conductive gel or couplant must be applied liberally to the patient where scanning will be performed. PrecautionsCoupling gels should not contain the following ingredients as they are known to cause probe damage: • Methanol, ethanol, isopropanol, or any other alcohol-based product • Mineral oil • Iodine • Lotions • Lanolin • Aloe Vera • Olive Oil • Methyl or Ethyl Parabens (para hydroxybenzoic acid) • Dimethylsilicone Planned Maintenance The following maintenance schedule is suggested for the system and probes to ensure optimum operation and safety.. WARNINGDo not use unrecommended gels (lubricants). They may damage the probe and void the warranty.

Probes and Biopsy 17-22 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Probe Discussion Introduction The LOGIQ 5 supports four types of probes: • Active Matrix Array (Convex and Linear). Active Matrix Array probes are usually designated by the prefix/suffixM. • Curved Array (Convex). Curved Array (Convex) probes, including `micro convex, are usually designated by the prefix/suffix C; the endocavity probe is designated by the prefix/suffix E. • Linear Array. Linear Array probes are designated by the prefix/suffix L; the linear intra-operative probes are designated by the prefix/suffix I or T. • Phased Array Sector. Phased Array Sector probes are designated by the prefix/suffix S; the biplane TEE probe is designated by the prefix/suffix B; the multi-plane TEE probe is designated by the prefix/suffix P. • Continuous Wave Doppler. Continuous Wave Doppler probes are designated by the prefix/suffix CWD.

Biopsy Special Concerns LOGIQ 5 Basic User Manual 17-27 Direction 2300002-100 Rev. 2 Biopsy Special Concerns Precautions Concerning the Use of Biopsy Procedures WARNINGDo not freeze the image during a biopsy procedure. The image must be live to avoid a positioning error. Biopsy guidezones are intended to assist the user in determining optimal probe placement and approximate the needle path. However, actual needle movement is likely to deviate from the guideline. Always monitor the relative positions of the biopsy needle and the subject mass during the procedure. CAUTIONThe use of biopsy devices and accessories that have not been evaluated for use with this equipment may not be compatible and could result in injury. CAUTIONThe invasive nature of biopsy procedures requires proper preparation and technique to control infection and disease transmission. Equipment must be cleaned as appropriate for the procedure prior to use. • Follow the probe cleaning and disinfection procedures and precautions to properly prepare the probe. • Follow the manufacturers instructions for the cleaning of biopsy devices and accessories. • Use protective barriers such as gloves and probe sheaths. • After use, follow proper procedures for decontamination, cleaning, and waste disposal. CAUTIONImproper cleaning methods and the use of certain cleaning and disinfecting agents can cause damage to the plastic components that will degrade imaging performance or increase the risk of electric shock. See ‘Probe Safety’ for more information.
