Theatrical Blood Effects Part 4 – From MilitaryMoulage.com

medical simulation squib

Part 4 of MilitaryMoulage.com’s article on Theatrical Blood Effects for Realistic Casualty Simulation has been released! Written by Suzanne Patterson, Curriculum Development Specialist / Instructor at Military Moulage, this is the next installment after part 3 covered covered some important elements to keep in mind for maintaining high realism results when selecting and using theatrical bloods in your casualty simulation event or training exercise. In part 4, Suzanne shares a few extra tips, tricks, and techniques we have employed and that you might find useful for your own active bleeding scenario requirements, including how to “release” effects at the right time using Squibs and pumps.

“Active bleeding is arguably central in creating a believable injury simulation psyche, from drips to flows, and there are a number of ways to rig blood loss from small areas all the way to significant hemorrhaging. For instance, blood trickles or drips from the mouth can be easily achieved from pre-filled gelatin-based blood capsules held in the mouth until bitten to give a slow bloody drip effect. We like to rig a small cut piece of cell-like sponge soaked in edible theatrical blood, and when placed in the mouth next to the lips it mixes with the saliva to make a nice dripping consistency. When ready to drip it out the actor simply inserts the sponge and manipulates it a bit with the teeth. For nosebleeds we also use specially made reticulated sponges prepared with edible blood that, when inserted in the nostrils, will “bleed” automatically upon the actor breathing through the nose. If you need a semi-drying dripped blood look from the ears, mouth corners, or nose that needs to be more stationary, we use blood colored gelatin to which some blood paste or additional glycerin has been added for a slightly wet effect. Our favorite trick is to use a scar making material mixed with some theatrical blood product. This method gives very high realism for film and TV use, and the best part is it’s durable and waterproof in wear.



Squibs and pump assemblies are great to use when you need a more significant amount of blood flow, such as from gunshots, impalement (stabbing), amputations, etc. Blood squibs are small sealed bags of liquid blood that are hidden under clothing, and that can be pyrotechnically rigged to explode, mechanically operated to flow by pneumatic liquid means, or simply break open upon surface impact. Pyrotechnic blood squibs involve electrical charges that trigger a ballistic action to spatter the blood bag, and that can be very dangerous or fatal if not done by a professionally trained and licensed technician. We prefer to use mechanically rigged squibs and pump assemblies because most often on a training exercise these have to be operated directly by the role player portraying the injury. One type of safe squib we make is from a dissolvable plasticized material containing blood powder, and rigged with a fast acting dissolving fluid that creates a gravity blood flow. This works great under clothing for gunshots or impalements. You can make your own blood squib bags to size from many kinds of pneumatic capable or collapsible containments, such as litre bottles, plastic zip close food bags, and even small cut off fingers of disposable gloves. They can be custom rigged to flow or release theatrical blood in a variety of ways and in the manner you need them to flow.”

Luna Innovations Provides TrueClot Blood Simulant

trueclot

Luna Innovations reached out to HealthySim recently to let our community know about their awesome simulated blood moulage products:

TrueClot is currently for sale and in use by military combat medical trainers, medical and Police, Fire and EMSprofessionals across the country. We’ve also started selling internationally as well. Our TrueClot Blood Simulant Concentrate can be reconstituted in water by the end user and our Task Trainer Kits are designed to be used in wound packing and advanced hemostatic gauze (such as QuikClot) training and simulation scenarios. Our Simulated Hemostatic Gauze is made using the same gauze material Z-medica uses to manufacture QuikClot and CombatGauze. Additionally, TrueClot launders from clothing and washes from skin with soap and water. As you can see in the video, you can also make instant simulated blood clots for moulage as well. One of our Fire Department customers uses the clots to simulate avulsed tissue as well simply by squeezing the water from the clots and applying it to a manikin. We also expect TrueClot to be approved for use on several advanced manikin simulators and the product is currently being tested by several advanced trauma manikin manufacturers with excellent results.”

 Check out this video below to see TrueClot in action:

Purchasable now are blood simulants (sold by the gallon), clotting agents, and Hemostatic Gauze. You can event get a sample kit for only $25!

LUNA’s TrueClot Blood Simulant is a highly realistic simulated clotting blood for use in realistic trauma and hemorrhage control training.  Realistic clotting for combat wound packing and hemorrhage control training can be achieved using our Simulated Hemostatic Gauze in a task trainer or hemorrhage simulator.  Simulated clots for moulage or surgical training can be created using TrueClotTM Blood Simulant and our liquid Clotting Solution.

 

TrueClot Blood Simulant is safe and non-hazardous, washes from skin and clothing with soap and water and can be disposed of in regular trash.  The simulated blood will not clot unless it comes in contact with our Simulated Hemostatic Gauze or Clotting Solution and is stable for 6-12 months if stored at room temperature.

Note: I have a question out to their representatives regarding tested use of this simulant with manikin products. I will update this article with the response when received.

 

For now, you can learn all about Trueclot at Luna’s Website!

Simubleed by Spectra Takes Moulage Blood to a HyperRealistic Level

Wow! Check out the next level of moulage bleeding with this new blood product “Simubleed” from Spectra!

simubleed

From the Simubleed website: “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. “

Simubleed Properties:

  • 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 Manikins)
  • 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

What about use with Medical Simulation Manikins?

From the website: “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.”

Have you used Simubleed? I would want to confirm that the blood does not clot WITHIN the manikin, making it tricky to restart tubes within the high fidelity systems. I have an email out to learn more about the use of the product within mankins — but kudos to Spectra for already experimenting the blood within medical simulation technology!

12/26/13 *UPDATE* A Spectra representative got back to me regarding my question: “My question is about clotting of the blood WITHIN the manikin tubes – how is this prevented, or “restarted” ? We have heard nightmares of internal arm tubes becoming useless after other blood products were left inside and coagulated — so I am just curious how far the tests went with Simubleed and the Laerdal manikin?”

“Regarding your question about the clotting within the manikin. Our simulant can exhibiting clotting in only 2 ways: One is when it comes in contact with the specialty gauze. The second one way that can induce clotting of SimuBleed is if the simulant is left on the manikin with air exposure for several days. We have left SimuBleed on our Laerdal manikin, with all the lines close, and have not observed any clotting or clogging of the lines. ”

MilitaryMoulage.com Curriculum Development Specialist & Instructor Suzanne Patterson shared Part 2 of her article on Theatrical Blood Effects for Realistic Casualty Simulation! MilitaryMoulage.com (or MMCIS™) provides “the highest quality moulage training workshops for military and civilian casualty simulation personnel, regardless of their skill level, which helps companies or individuals achieve the greatest value for training investment dollars.”

bleeding headwound moulage

Excerpt from the article:

“High fidelity blood simulation is a pivotal component in creating true-to-life bleeding traumas for accurate response in training, so there are some physiology facts to keep in mind about it when you are planning blood loss in your scenarios.  First of all, the human body contains roughly a gallon plus a quart of blood, about 168 ounces, and depending on the body size.  Clinical symptoms of hypovolemia (shock due to blood loss) becomes apparent after about 20% or 1/5th of whole-blood volume has been compromised, so be aware of this detail when assigning large blood loss type of injuries. 

Blood color is also an important factor because there are two distinct types of blood that circulate throughout the body.  Artery blood is oxygenated as it moves away from the heart and lungs, so it is a lighter or brighter red looking blood. Venous blood is a darker red hue because it is oxygen depleted and high in carbon dioxide as it travels back to the heart.  You’ll need to determine how much theatrical blood of both colors will be needed to portray active bleeding through the flowing, dripping, or oozing from compromised veins and arteries portrayed, as well as any splashing, splattering, or smearing resulting from contact or an impact.”
