Allow me to provide some information on this matter which is currently gaining importance amongst clinicians. I have attached herewith a copy of a research based poster presented at the European Society of Anesthesiology (ESA) meeting in Munich in June 2007. This also appeared in Paediatric Anaesthesia, Vol. 17, June 2007, pp 606-607(2) as a prize winning research paper. Optimal spectral irradiance for laryngoscopy
Dr. E. Lewis quotes “ Infra red light has been shown to be detrimental to optimal laryngoscopy……. Blue light corresponds to peak haemoglobin absorption (415 nm) and therefore enhances the view of capillary vessels within the surface mucosa. … …Green light defines deeper structures more clearly. Specific combinations of blue and green light spectra may provide the best conditions for intubation. Light Emitting Diodes (LEDs) have the advantage of producing light in a more appropriate part of the spectrum”. Dr. Lewis further concludes that “….. laryngoscopes with LEDs may provide superior intubating conditions than that currently available with incandescent light sources. LEDs can be further modified to emit the optimal spectral irradiance required for laryngoscopy. This may prove invaluable when presented with a difficult airway. “ Accordingly, Truphatek has incorporated the LED as the preferred light source into the Truview EVO Infant blade for pediatric intubation; in the Tru-LED green system ergonomically designed rechargeable handle and in the latest product from our development department – the Tru-Lite disposable combination blade and handle. Further, it is our intention to continue to incorporate the use of LEDs to provide optimal intubating conditions into all future Truphatek products. I hope this information helps you and your customers to choose the best products to meet their clinical needs.

Our Goods Transporter is asking us to provide the full classification that applies to your Trucharge™ Lithium Ion Batteries since they are saying that very strict Federal Laws apply if these batteries are defined as hazardous material. Jessica, N.C, USA |

The capacity of the Lithium-Ion that we use in Trucharge is 2Ah which represents an equivalent Lithium content of 0.6 Gram. This allows them to be defined as non-hazadous and so they are not restricted for shipping purposes either by ground or by air. The full classification for transportation is : DOT (per CFR 172.101) and IATA/ICAO Proper Shipping Name: Lithium Batteries UN Number: UN 3090 (UN 3091 for Lithium Batteries in Equipment) Hazard Classification: Class 9 (Misc.) Packing Group: II Labels Required: MISCELLANEOUS HAZARD CLASS 9 Other: CARGO AIRCRAFT ONLY Non-Hazardous Batteries: If the batteries contain less than 1.0 grams of lithium or lithium alloy per battery pack they are not restricted for shipping purposes by ground or air. If single cells contain less than 0.5 grams of lithium or lithium alloy, they are not restricted for shipping by ground or air.
