In hemorrhagic shock, veins collapse from hypovolemia and a flat tourniquet-style band can't raise a usable target — and uniform flat pressure can compress the artery along with the vein, defeating the purpose.
What raises a vein when a flat band can't?
The BOA's rolling compression mechanism rolls venous blood distally into the limb, engorging the peripheral veins while arterial inflow continues — raising a visible, palpable target even in low-volume patients. Originally developed for the Armed Forces, it's built for the hard sticks: Class III–IV hemorrhage, sclerotic or fragile diabetic veins, larger body types (BOA XL), and difficult pediatric or elderly access. A Quick-Click connector applies one-handed; a two-finger Quick-Release frees both hands the moment the catheter is in.
Why the BOA
Rolling Compression
Rolls venous blood distally to engorge peripheral veins while arterial inflow continues.
Built for Hard Sticks
Raises a target in hypovolemic, sclerotic, large, pediatric, or elderly veins a flat band misses.
Quick-Click / Quick-Release
One-handed application; two-finger release frees both hands for cannulation.
Standard & XL
Standard fits up to 18″; XL stretches ~50% longer to 27″ for larger or edematous limbs.
Standard vs. XL
| Standard BOA | 7.5″–18″; White; typical adult upper extremity |
| BOA XL | 10″–27″; White w/ Red stripe; larger or edematous limbs, upper-arm access |
| Key Difference | XL stretches ~50% longer; red-stripe visual differentiation |
