Disclosed are methods, materials and devices for approximation of blood volume in a fluid, such as in a biological fluid collected during a surgical procedure. The method and devices include the use of a RBC flocculant, such as polyDADMAC, and an approximate blood hematocrit for the type of animal, as well as a calculated RBC packing ratio corresponding to the collection device being used. Also provided is a Blood Indicator Panel (BIP), comprising a series of markings calculated from an observed red blood settlement volume, the average animal type hematocrit, and a calculated RBC packing ratio “η” value for the collection device. Pediatric (about 200 ml or 250 ml size container), adult human (about 1,000 ml-1,500 ml) and veterinary (about 500 ml-2,500 ml) collection containers are also disclosed, that include a RBC flocculant, for use in approximating blood volume in a fluid.
A container for rapid blood detection and blood loss assessment comprising at least one surface suitable for settling of red blood cells, said container being comprised of a material through which a visual assessment of settled red blood cells can be made, a red blood cell flocculant, and at least two inlet ports, wherein at least one inlet port is suitable for receiving a material comprising blood.
The container of claim 2 having a volume capacity of about 100 ml, about 250 ml, about 500 ml, about 1,000 ml, about 1,200 ml or about 2,000 ml.
The container of claiml wherein the material through which a visual assessment of settled red blood cells can be made is a clear polymeric material.
A collapsible fluid collection container for rapid blood detection and blood loss assessment comprising a red blood cell flocculant, a series of calibrated markings corresponding to approximate blood volume in a fluid, and at least two ports, said collapsible fluid collection container comprising a material through which a settled red blood cell level can be visually assessed.
