TABLE 4 Tourniquet Design Thoughts
Tourniquet Liked Considerations
SICH Limb-encircling strap: Limb-encircling strap:
– hook and loop adhered equivalently for all 30 – sharp edge cut skin when pulled through side slot of the rod-
applications securing modified triangle (consider oversewing or other edge
change)
– end triangular tab catches on strap-securing part of triangle
when releasing (consider zigzag stitch or other end change)
– with reuses, wear occurs under the windlass rod
– consider making strap longer so it can still be pulled through
securing triangle when on medium to large thighs*
Inner strap: Inner strap:
– no unnecessary slack so tightening starts when rod – no considerations
rotation starts
Base area: Base area:
– very flexible, can secure strap and use tightening system – with reuses, wear occurs in the restricted opening under the

on 14.0cm-circumference cylinder windlass rod
– no sharp edges pushing into skin
– restricted opening through which the inner strap goes
up to the rod may help keep the rod a securable distance
from the securing triangle
Redirect buckle (simple or triglide): Redirect buckle (simple or triglide):
– can be simple threaded for easier development of strap- – could consider rounding the strap-engaged edge when threaded
pull tension as a simple redirect (for lower friction when pulling the
– can be triglide threaded to encourage hook-and-loop redirected strap tight around the limb)
interaction for better strap security
– metal, seems robust
– easy threading (good-sized openings)
Windlass rod: Windlass rod:
– metal, seems robust – no considerations
– strap through rod with rounded slot edges
– remained a securable distance from securing triangle
with up to 5.5 total turns of 180° each
Triangle rod- and strap-securing system: Triangle rod-securing system:
– metal, seems robust – slight differences among tourniquets in the opening width
– good rod-securing system (easy use in lab) between the two inward prongs near the top of the triangle
– seems like a good strap-securing system (easy use in lab
when strap long enough for use)
DNIPRO Limb-encircling strap: Limb-encircling strap:
– hook-and-loop adhered equivalently for all 30 – consider making strap longer so it can still be secured under the
applications time strap across the top of the top-opening bracket when on
medium to large thighs*
Inner strap: Inner strap:
– see considerations – unnecessary slack, delays start of tightening until approximately
90° of rod rotation†
Base area/strap connection: Base area/strap connection:
– relationship of base plate and strap remains consistent – no considerations
over multiple uses (30 lab uses)
Base area: Base area:
– edges rounded for least skin discomfort – 9cm-long plate strongly resists tight radius, not very flexible for
– no exposed hook of hook-and-loop pushing into skin smaller circumference limb segments
Redirect buckle (simple): Redirect buckle (simple):
– simple redirect for easy development of strap-pull – could consider smoothing and rounding the strap-engaged edge
tension (for lower friction when pulling the redirected strap tight around
– simple redirect for limited threading choices the limb)
– metal, seems robust
– easy threading (good-sized opening)
Windlass rod: Windlass rod:
– metal, seems robust – no considerations
– strap through rod with rounded slot edges
– remained a securable distance from securing bracket
with up to 3.5 total turns of 180° each
Top-opening bracket rod- and strap-securing system: Top-opening bracket rod- and strap-securing system:
– easy to place rod into (in lab) – some interference with rod turning
