Learn how to mix simulated blood concentrate for realistic trauma drills, clean up non-staining fake blood, and reuse training blood safely without ruining gear.
Quick answer
Mix simulated blood concentrate by adding it to water at the ratio your training scenario requires, starting with a 1:4 concentrate-to-water blend for standard drips and adjusting for darker or thinner effects. Use non-staining fake blood for trauma drills on manikins and gear, clean spills promptly with soap and water, and reuse only what you can store sealed and cool. For large-volume training, a 1-gallon concentrate like the Simulated Blood Concentrate (Non-staining) from North American Rescue gives you consistent batches without constant reordering.
Choose the right dilution for each drill
There is no single correct ratio for simulated blood. A thinner mix works for capillary bleeding and soaked dressings, while a thicker mix reads better for arterial spurts or pooled blood on a training mat. Start with a 1:4 concentrate-to-water ratio, then add concentrate in small amounts until the color and viscosity match your scenario. Mix in a clean container you reserve for training use only, and stir gently to avoid foaming. If you are preparing multiple stations, make one larger batch rather than several small ones so every trainee sees the same product.
Prepare the training area before you pour
Even non-staining fake blood can leave residue on porous surfaces, so protect what you cannot wipe. Cover floors and tables with disposable plastic sheeting, tape seams, and keep a dedicated cleanup kit within arm's reach. Dress manikins and trainees in gear you have already designated for moulage. Have paper towels, a spray bottle of soapy water, and a sealable waste bag staged before the first drop lands. This five-minute setup prevents most of the cleanup problems that turn a short drill into an hour of scrubbing.
Apply blood realistically, not randomly
Realism comes from placement, not volume. Drip blood onto the wound site, let it run with gravity, and use a syringe or squeeze bottle to control flow for spurting wounds. For gunshot or burn scenarios, pair the blood with the appropriate wound simulator so trainees see a complete injury pattern. The Techline Trauma Gunshot Wound in a Box Simulator and the Techline Trauma Burn Torso Simulator Adhesive are designed for this kind of hands-on practice, and both accept simulated blood products. Keep a small cup of water nearby to thin drying edges and refresh the look between repetitions.
Clean up while the blood is still wet
The single biggest cleanup mistake is waiting until the end of the day. Non-staining formula helps, but dried concentrate can still bond to fabric and textured plastic. Wipe manikins and hard surfaces with warm soapy water as soon as each station finishes, then rinse and dry. For clothing and straps, blot first, then wash according to the garment label. If a stain persists, re-wet it and repeat rather than scrubbing harder, which can push pigment deeper into the fibers.
Store and reuse concentrate safely
Reuse is practical for concentrate, not for mixed blood that has already touched a manikin, floor, or trainee. Keep the original concentrate sealed, upright, and out of direct sunlight, and mix only what you need for the day. If you must store a mixed batch, label it with the date and ratio, keep it in a sealed container, and discard it if the color, smell, or texture changes. Never return used blood to the concentrate container. The 1-gallon Simulated Blood Concentrate (Non-staining) is sized for repeated training cycles, so you can mix fresh batches without opening a new jug every session.
Step-by-step: mix, apply, clean, and store
- 1. Mix a test batch: Combine concentrate and water at 1:4 in a clean training-only container. Stir gently and check color and viscosity against your scenario. Checkpoint: if the mix looks too thin, add concentrate in small increments rather than dumping more water.
- 2. Stage the area: Lay plastic sheeting, tape seams, and set out soapy water, paper towels, and a waste bag before any blood is poured. Common mistake: skipping floor protection because the formula is non-staining. Non-staining does not mean no cleanup.
- 3. Apply with control: Use a syringe or squeeze bottle to place blood at the wound site and let gravity do the work. Match the flow to the injury, not the drama. Checkpoint: trainees should see a believable injury pattern, not a puddle.
- 4. Clean while wet: Wipe manikins and hard surfaces with warm soapy water immediately after each station. Blot fabric, then wash per the label. Common mistake: letting blood dry on gear. Dried concentrate takes more effort to remove than wet blood.
- 5. Store concentrate, discard mixed blood: Seal the original concentrate upright, away from sunlight. Label and refrigerate any mixed batch you keep, and discard it if color, smell, or texture changes. Next step: never return used blood to the concentrate container, and mix fresh for each training day.
Training blood and simulator facts
- Simulated Blood Concentrate (Non-staining) - 1 Gallon: This 1-gallon container of Simulated Blood Concentrate is a non-staining training aid designed for realistic medical and tactical simulations, and the concentrate format allows for easy dilution and preparation of simulated blood. One gallon of concentrate makes multiple diluted batches, which suits recurring trauma drills and multi-station training days better than pre-mixed bottles.
- Techline Trauma Gunshot Wound in a Box Simulator: The Techline Trauma Gunshot Wound in a Box Simulator simulates a gunshot wound for hands-on training practice and comes in a compact, boxed format for easy storage. Pairing this simulator with simulated blood lets trainees practice wound assessment and bleeding control on a realistic injury pattern instead of a generic manikin surface.
- Techline Trauma Burn Torso Simulator Adhesive - Large: The Techline Trauma Burn Torso Simulator Adhesive in Large size is a training aid with an adhesive backing for convenient application to a training manikin, helping provide a realistic representation of a burn injury on the torso. Because it adheres to a manikin, it stays in place during movement and allows blood products to be applied directly to the simulated wound for moulage realism.
