Biolife’s UrgentQR is a powder that stops bleeding instantly. Composed of a non-toxic mixture of hydrophilic polymer and a potassium salt, the powder independently uses the blood from a wound to form a hematrix scab, protecting against infection and contamination. Within one minute, 98 percent of clinical cases stopped bleeding. A majority stopped within 15 seconds. Like bandages, UrgentQR is FDA classified as an Exempt Class I device and requires no prescription. It is not metabolized by the body or biologically derived.
