Robust Design
Welch Allyn’s laryngoscope design uses a single piece of 304-series stainless steel as its load-bearing member. All competitive blades are constructed from multiple pieces of stainless steel or brass that are bonded together using a solder or braze. These solders or brazes are vulnerable to corrosion due to harsh conditions associated with many sterilization methods. This one-piece construction of the Welch Allyn blade is more robust than the typical competitive product. Furthermore, its one-piece blade construction eliminates the potentially weaker soldered or brazed joint.
Design Features
Welch Allyn’s innovative design incorporates an easy-to-remove light pipe that eliminates the difficult-toclean areas of most competitive laryngoscopes.
Another feature designed to help improve the cleaning of a Welch Allyn blade is its surface finish. Typical laryngoscope finishes have a surface roughness of 32μ in. The surface finish used on all Welch Allyn blades has a roughness of just 8μ in. This creates a surface texture that is approximately four times smoother than competitive blades, resulting in an easier-to-clean, stain-resistant laryngoscope blade. What’s more, the surface finish is not a plating, and therefore does not alter the 304-series stainless steel construction of the blade itself.
Brighter by Design
The Welch Allyn Halogen HPX lamp is the latest technology in gas-filled lamps. By filling the lamp with a high-pressure mixture of halogen and xenon gases, we have invented a miniature lamp that is more than 30% brighter and whiter than standard halogen lamps. Blades can be economically upgraded from lamp to fiber-optic illumination
More Value by Design
There are primarily two causes of reduced light transmission in fiber optic laryngoscopes: fiber optic breakage and epoxy blockage. Light degradation caused by fiber optic breakage will occur in varying degrees in any laryngoscope that is subjected to severe changes in temperature. Blades are repairable at a fraction of the cost of a replacement blade
The Miller blade, originally designed in 1941, was modified in 1990 to improve its functionality and field of view. For instance, the base of the blade was flattened to allow the tongue to be swept aside, rather than compressed. This has allowed better viewing, without altering the blade’s width or height.
