Welch Allyn Laryngoscopes
Designed Smart
Robust Design
Welch Allyn’s laryngoscope design uses a single piece of 304-series stainless steel as its load-bearing member.
A
ll 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-to-
clean areas of most competitive laryngoscopes.
Removable Light Pipe
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.

There ar
e 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
degr
ees in any lar
yngoscope that is subjected to sever
e changes in temperatur
e.
Reduced Light Degradation
> When a fiber optic laryngoscope is steam-sterilized, the heat
involved causes the epoxy (used to hold the fibers in place
within the fiber optic bundle) to expand and extrude past
the end of the light pipe.
> The epoxy cools following the autoclave pr
ocess and
hardens over the optics, blocking light emissions from those
fibers. As mor
e and mor
e fibers ar
e blocked, less and less
light is emitted and the accuracy of the intubation pr
ocess
may be jeopardized.

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.
