(benzacaine, lidocaine, tetrocaine) compound are frequently used • Area MUST be cleaned prior to treatment Post-treatment Instructions • Clean area • Apply dressing to treated area – Apply ointment to keep area moist (Aquaphor, bacitracin or even Vaseline are commonly used) – Cover area and ointment with a non-stick dressing (telfa) • Advise patient to keep clean and to not pick, scratch or aggressively wash the treated area Click to edit Master title style • Click to edit Master text styles Operation, Safety & – Second level • Third levelMaintenance – Fourth level » Fifth level General Specifications • Repetition rates: – 1, 2, 3, 4, 5 Hz – Hz = pulses per second • Spot sizes are: – 755 nm – 2mm(Gold), 3mm(Black), 4mm(Red) – 1064 nm – 2mm(Gold), 3mm(Black), 5mm(Red) – 532 nm – 2mm(Gold), 3mm(Black), 5mm(Red) Wavelength & Spot Sizes Wavelengths & Spot Sizes Protective Eyewear • Since the Alex Trivantage has 3 different wavelengths, the appropriate eyewear must be worn at all times • This includes proper Optical Density AND wavelength • The Alex Trivantage has a screen reminding users of these requirements Eye Safety ** WARNING ** • The Alex Trivantage 532nm and 1064nm hand pieces contain lasers and require special handling considerations for optimum performance and safety. • Unlike the 755nm hand pieces, these hand pieces deliver a non-diverging beam. If you pulse the laser with the hand piece aimed at the wall, floor, or other object several meters away, it will create a burn mark • Always take precaution to ensure that all persons in the room, while the laser is in use, utilize the appropriate eyewear. Appropriate Eyewear • 532nm @ 6.0 Optical Density • 755nm @ 6.8 Optical Denisty • 1064nm @ 5.7 Optical Density Other Safety Concerns • The Alex Trivantage 532 nm and 1064 nm hand pieces contain Factory Aligned Lasers and require special handling considerations for optimum performance and safety. • The Hand Pieces can break • SOMEONE COULD GET HURT Other Safety Concerns • DO NOT DROP THE HAND PIECES! • The internal components are fragile! They are factory aligned under strict environmental conditions – cannot be repaired in the field! Handpiece Storage • • • ALWAYS store the hand pieces in the top compartment of the laser. The lid should be kept OPEN after the laser has warmed up and close the lid when the laser is off. Temperature control issues. • • New hand pieces need to be warm before use Not too warm as with the cover closed and running). Foot Pedal Safety • Prior to performing treatments • Ensure that all personnel in the treatment room are safe by locking the front wheels and visually checking that the footswitch air hose is free and clear. • If the laser or anything else rolls on the hose while firing the laser, it will continuously pulse non-stop unexpectedly. • The Emergency Stop Button will be your only way to stop the laser from pulsing.

New Distance Gauge Maintenance • O-ring keeps protective lens locked into position • O-ring can be removed similarly to other distance gauges • DG window should be cleaned or replaced as described in the “Alex2/Alex TriVantage DG window cleaning & replacement procedure” (850200-0916 Rev C. or later) Multi-Spot DG Multi-Spot DG Protective Window O-ring Distance Gauge Differences 755nm “Fingernail type” Distance Gauge 532/1064nm LPL “Ring Type” Distance Gauge DG Window Differences ALX-44-LPWN ALX-44-07WN ALX-44-XXXX (Multi-Spot) **THESE ARE NOT INTERCHANGABLE Most reliably sorted by their size, the glass window inserts for the two distance gauges are different and cannot be mixed. 755nm Distance Gauges • The 755nm Distance Gauges (DGs) have a finger nail like probe • These DGs fit inside the end of the hand piece • Older AlexLAZR DGs do not have a protective window. • Newer AlexLAZR and ATV DGs have a protective window • The same 755nm DGs can be used with the 2mm, 3mm and 4mm hand pieces LPL Distance Gauges • The 532/1064nm LPL Distance Gauges (DGs) have two legs and target ring at the tip • The LPL DGs fit over the end of the hand piece • They have protective windows that must be cleaned periodically • They fit all spot sizes: 2mm, 3mm, 4mm, and 5mm hand pieces Important Notes • The Laser Pumped Laser (LPL) distance gauges are designed to be used only with the 532nm & 1064nm hand pieces Important Notes • When using the 755nm hand piece, the fingernail DG should always be used • This DG has a window that improves reliability of the delivery system by protecting the 755nm HP optics • This window must be cleaned to maintain proper system output Alex TriVantage vs AlexLAZR • The AlexLAZR distance gauge DID NOT have a window • Many practitioners may not be used to cleaning or maintaining these new windows. • DG window should be cleaned or replaced as described in the “Alex2/Alex TriVantage DG window cleaning & replacement procedure” (8502-00-0916 Rev C. or later) Warning!! • It is important to inspect and clean the DG window frequently so debris does not get burned into its surface • If the optical coating on the DG window develops burn marks, the amount of energy reaching the treatment area may be significantly reduced or the laser beam may be deflected resulting in the HP or DG becoming damaged • Burn marks on the coating may occur due to several reasons: – Dust/debris collecting on the surface and then being burned on via the laser beam – Debris collected during normal attachment of the DG to the HP body (keep the DG clean) Identifying Burn Marks • Hold the DG at an angle such that light is reflected off the window surface • Burn spots will appear as small discolored rings/spots on the surface • Their size (specks of dust to a pencil point) will vary depending on the extent of debris build up and the time burning has occurring • Minor burn marks may be cleaned off. If unable to remove, further rapid degradation at these spots should be expected to occur Adverse Consequences of Burn Marks • Reduced delivered fluence to the treatment area as more energy is deflected or absorbed by the burn area and therefore not reaching the treatment area • Increased heat build up noted in the HP possibly resulting in frequent or unexpected system faults • Burn marks can cause rapid degradation of the DG window Inspection Procedure • Wear dustless gloves to prevent smudges or fingerprints on the window • Place the laser in stand-by and remove the DG from the HP assembly • Look through the DG window while pointing the DG’s far end towards the ceiling light • Rotating the DG at this position will cause debris on the window to rotate, making it more apparent Removing the Window • Working over a clean surface, remove the O-ring that is holding the window in place • Use tweezers, or a pointed object in notch to gently pull the O-ring towards the center of the window until the O-ring is free from the groove • Turn the DG upside down allowing the window to fall out (if needed, gently tap the side of the DG with your finger) Cleaning the Window • When cleaning used windows, use a 10% bleach & water solution, mild soap & water or alcohol • Rinse thoroughly with clean water and dry with a lint free tissue • Re-inspect the window and compare with the window Acceptability Chart (see next slide) • If unacceptable, replace the window Window Acceptability Chart Acceptable window Examples: Unacceptable window Examples: Replacing the Window • Grasp the window by the edges and place it back into the DG so it is resting flat on the ledge • Re-insert the O-ring into the groove. • Use tip of tweezers or pointed object and gently push the O-ring fully into the groove being careful not to touch the window Click to edit Master title style • Click to edit Master text styles – Second level Thank You • Third level – Fourth level » Fifth level
