Advanced Blood Simulant (patent pending)

Advanced medical training of first responders and emergency medical personnel both in the civilian and military world is critical to preserve lives in the line of combat and emergency situations. Currently, such training uses bovine blood, which not only implies a bio-hazard risk, but it is also expensive and cruel to animals.
As part of a US Army sponsored SBIR (Small Business Innovation Research) project, Spectra Group Limited has developed a new blood simulant that resembles human blood: SimuBleed 1000. SimuBleed 1000 mimics the physical characteristics of human blood (color, viscosity, tactile feel) without any hazardous components, special transportation or sacrifice of live animals. SimuBleed 1000 is cost-efficient and easy to clean.

Making the training of medical personnel as realistic as possible translates in a more accurate response during an emergency. Currently, one major drawback is the lack of a blood simulant that precisely behaves like human blood. For this reason, military medical personnel have been forced to use animal blood during training to more closely resemble what would be expected in a battle field or an emergency situation. The blood simulants currently available do not realistically represent  blood in terms of their color, tactile feel, viscosity or clotting properties.

With Simubleed 1000, Spectra Group has developed an advanced blood simulant that possesses the color and viscosity of human blood and also clots in the presence of a specialty laminate similar to those used by the military personnel in the field. The gauze laminate has been especially designed to work with SimuBleed 1000 and induce clotting upon coming into contact with the gauze.
Simubleed 1000 is a completely synthetic blood simulant, with NO animal or biological content. it is bio-hazard FREE, stable (unlimited shelf life), and does not require special transport or storage, which also makes it cost-efficient.


  • Dark red color, which is an excellent color match for venous blood
  • Rheology and flow profile close to human blood (more viscous than water)
  • Clots quickly in the presence of the special gauze laminate (although slower, clots in presence of air as well)
  • Can flow through narrow and wide passages (as those found in Laerdal Mannequins)
  • Once it dries, it becomes "flaky", just like dried blood
  • Unlimited shelf life. No special storage or transportation required
  • Safe and easy to clean. No biological or hazardous components
  • Inexpensive
  • "Metallic" smell (optional)
  • Brighter color to simulate arterial blood can be accommodated upon request

SimuBleed 1000 has been tested on Laerdal Mannequins embedded with a bleeding simulator containing narrow and wider passages to simulate, realistically, venous and oozing bleeding. Since personnel needs to be trained to stop bleeding and conduct hemorrhage control as quickly as possible, the coagulation properties of SimuBleed 1000 allows trainees to have a real feel as to how quickly one must respond and how long it takes for a given wound to stop bleeding. Once the laminate gauze is applied to the wound, coagulation of the blood simulant begins until the bleeding stops. 


The contact of SimuBleed 1000 with the gauze laminate triggers a chemical reaction. As a consequence, the blood simulant thickens, accurately resembling the coagulation of blood. Until now, no other blood simulant has been able to achieve clotting properties that mimic those of human blood. SimuBleed 1000 and the gauze laminate are intended to be used as a tandem product, since the same techniques are applied in the battle field to stop bleeding from wounds and control hemorrhagic situations. The use of a regular gauze or any other super absorbent tissue will not induce the coagulation of the simulant.

Although SimuBleed 1000 was developed for the training of military personnel, any situation that requires the use of a blood simulant could benefit from the unique properties of this advanced blood simulant: from civilian emergency training to theatrical blood, SimuBleed 1000 will not only look like real blood, but it is also safe and easy to clean.
