E-MacIntosh Laryngoscopes
E-MacIntosh Blade
Features
Lightweight. Reduced handle and
blade weight for improved balance
and maneuverability facilitates even
the most difficult intubations.
Convertible. Blades easily convert
from lamp to fiber optic illumination.
Makes upgrading economical.
Repairable. Replace deteriorating
light pathways for a fraction of the
cost of a replacement blade.
Improved design. Reduced
proximal blade height assists in
intubating patients with limited oral
access.
One-piece construction. Single-
piece stainless steel blade ensures
blade integrity (no soldered joints).
Halogen HPX
illumination. Our
fiber optic blades feature Halogen
HPX lamps for true tissue color and
consistent, long-lasting illumination.

E-MacIntosh, or “English”-MacIntosh, blades are the most popular style of laryngoscope blade
outside of the United States. The design, although based heavily upon the original MacIntosh
blade, differs in several aspects. First, the curve of the E-Macs is more continuous from the
proximal to distal end. This improves lifting mechanics. Second, overall length is increased to
help assist intubation in patients with an anterior larynx. Finally, the profile or height of the
instrument had been reduced for easier intubation in patients with limited oral access.
The E-Mac series, introduced by Welch Allyn in June of 1992, is the result of continual
discussions with customers regarding improvement in the design and manufacture of
laryngoscope blades. This is the first new line of laryngoscope blades manufactured by Welch
Allyn since our inception of the Miller laryngoscope in 1941.

When developing this blade with Welch Allyn in 1941, Dr. Miller was attempting to overcome
f
our major shortcomings of existing straight blades. The first was the height of the proximal
portion of the blade, which he reduced by compressing the “C” shaped cross-section into a
m
odified “D” shape. This change helped to prevent dental trauma and allowed intubation of
patients with small oral openings. Second, because most blades were curved distally only at the
tip, they did not facilitate lifting of the epiglottis. This problem was solved by starting the curve
two inches back from the tip providing a positive lifting action. Third, existing blade styles were
wide distally; this limited the manageability of the instrument, prohibiting intubation. Therefore,
the Miller blade was designed with a narrow tip. Finally, the tongue or base of the Miller blade
was rounded to prevent pushing the tongue into the floor of the mouth.
In 1990, Welch Allyn modified the Miller blade to improve its functionality and field of view.
First, the blade or tongue of the blade was flattened so that the tongue would be swept aside,
rather than compressed. This was implemented due to the present technique of sweeping the
tongue rather than compressing. The flat base helps to hold the tongue out of the field of view.
Overall field of view was increased by modifying the cross-sectional area of the blade without
altering width or height.
