Why It Matters

90%

of potentially survivable U.S. combat deaths in Iraq and Afghanistan were caused by bleeding (Military Times)

5% vs 19%

24-hour mortality for combat casualties given blood during medical evacuation vs. those who were not (JAMA, 2017)

48,000+

prehospital blood transfusions documented by U.S. EMS in 2024-2025, 42% of them in rural areas (NEMSIS)

31,000

Americans estimated to bleed to death each year from injuries they could have survived (Dallas Morning News)

The Barrier to Entry

8 hrs

in a freezer before every use. Ice-pack coolers can't deploy on short notice. (Source)

24 hrs

is all an ice-pack cooler lasts in 111°F heat, half its normal time. (Source)

29 lb

is what the older powered blood fridge weighs. Too heavy for one medic to carry. (Source)

The FDA

regulates every blood storage device as a medical device. Anyone entering this market has to meet those rules. (Source)

Not a Cooler. A Powered Medical Device.

No Ice

Powered heating and cooling keeps blood at the right temperature in extreme heat or cold. No freezer prep.

15 lb

fully loaded with battery (7 lb empty). One medic can carry it, at about half the weight of the older powered unit.

<10 sec

battery swap with no downtime. Runs on standard military batteries or plugs into a vehicle or aircraft.

Drones

and robots. Built to ride on drones, robotic ground vehicles and unmanned boats. Every trip is temperature-logged.
