A03-178 TITLE: Noninvasive Treatment of Hemorrhagic Shock TECHNOLOGY AREAS: Biomedical ACQUISITION PROGRAM: DSA, MRMC OBJECTIVE: To develop a small, simple, lightweight noninvasive device to help sustain blood pressure after cardiovascular collapse from a battlefield injury until more definitive invasive treatment is available. This can be accomplished by decreasing intrathoracic pressure through a device that can be self-applied by the injured soldier or with assistance, if necessary. DESCRIPTION: Research in the field of cardiopulmonary resuscitation has lead to the recent application of an inspiratory impedance threshold valve (ITV) to augment blood pressure during cardiovascular emergencies. ITV application has been tested in animals and patients during cardiac arrest and in animals during experimental hemorrhagic shock. In both settings, this simple approach results in a marked increase in blood pressure, thereby buying time until more definitive therapy (e.g., fluid resuscitation) becomes available. During the decompression phase of standard CPR, a small vacuum is created within the chest relative to the rest of the body every time the chest wall recoils back to its resting position (2). This draws venous blood into the right heart and air into the lungs. As such, ITV application can increase the vacuum within the thorax and double blood flow to the heart and brain. ITV application has increased survival rates in experimental animals and patients undergoing CPR. In a hemorrhagic shock model, application of an ITV resulted in restoration of normal blood pressures for >30 minutes in spontaneously breathing pigs, whereas pigs treated with a sham ITV remained in severe shock and died. However, ITV application has not been developed and tested in a human model of hemorrhage. Therefore, the purpose of this application is to develop and optimize features of a small, simple, lightweight ITV device and to prove the applicability of the ITV for treatment of combat-related shock. PHASE I: This phase should result in a proof of concept workable device for application on humans. In order for the ITV to work well, it needs to be: a) effective and easy to use by the medic, b) seal well with the face of the patient, and c) enable the soldier to breathe through the ITV comfortably for a prolonged period of time. To optimize the value of the ITV for the treatment of hemorrhagic shock on the battlefield, it will be necessary to: a) determine a tolerable inspiratory resistance or cracking pressure for the ITV that will prove effective in increasing cardiac output and blood pressure in humans, b) assess the work of breathing through the ITV; and c) optimize the face mask to skin interface. It will therefore be necessary to measure key hemodynamic and physiological parameters in normal human subjects to determine if the ITV can increase stroke volume and blood pressure at breathing resistances that can be tolerated under normal baseline physiological conditions. PHASE II: This phase should result in a device that can be used to maintain blood pressure in a human model of moderate to severe central hypovolemia and shock. The Human Physiology Laboratory at the US Army Institute of Surgical Research has developed such a human model using lower body negative pressure (LBNP). The human LBNP model will be used to establish proof of concept that the ITV enhances venous return by a simple thorax vacuum mechanism under conditions of central hypovolemia. This phase should also result in a practical device that can be used under conditions that will be found in the battlefield. Finally, several different versions of the ITV face mask combination will be assessed to develop a device that functions as intended with an excellent seal over the nose and mouth. PHASE III COMMERCIALIZATIONn: This technology will have immediate battlefield application, and civilian pre-hospital application to be used by paramedics in the field or on ambulances for treatment of cardiac arrest and shock secondary to blood loss. This may particularly apply to rural or other delayed extraction situations where availability of fluid resuscitation and other life sustaining interventions may be delayed. In addition, an ITV device could provide potential military application to help pilots counteract severe gravitational forces, and civilian application for the treatment of excessive heat exposure and heat stroke.

A03-179 TITLE: Non-Ceramic Small Arms Protective Inserts in Personnel Armor TECHNOLOGY AREAS: Human Systems ACQUISITION PROGRAM: PM-Soldier Systems OBJECTIVE: Develop durable non-ceramic, low cost, lightweight personnel armor ballistic protective inserts for small arms protection. DESCRIPTION: The primary ballistic protection offered against small arms rounds is based on ceramic with fiber-reinforced composite backing. Due to the nature of the materials used, these systems can be damaged or degraded during use. There are a number of current issues that make the development of this technology very desirable. Typically in current armor systems, non-ballistic materials are added to a ballistic insert to decrease the potential of field use damage, which adds parasitic weight to the system. Additionally, the current durability tests for such armors do not adequately simulate the in-service conditions nor is there an efficient non-destructive inspection methodology to assess the ballistic integrity of the armor systems during use in the field. The desired outcome of this effort is a durable, potentially lower cost and light weight ballistic protective insert system which provides the same or better ballistic protection against small arm ball rounds to include various 7.62 mm rounds as well as 5.56 mm rounds. These projectiles may contain a lead or steel core and can be defeated by current ceramic-based technology. The technology must offer a multiple hit capability (at least 3 defeats). The cost of developed technology should not exceed $450.00 in a finished product and should be able to withstand multiple drops at any location on the plate when dropped from a height of at least four feet on to a rigid surface (e.g., concrete, rocks). Approaches to this effort should be focused on advanced fiber-reinforced composites or advanced fibers and nanoparticle reinforced composites except materials which may cause environmental or personnel hazards. Technology is subject to export controls under current USML. PHASE I: Research and develop one or more material systems which have potential to meet current Army’s performance specification for dual-curved small arm protective inserts at 5.0 lb/ft2 or less. Develop material processing and designs to optimize the ballistic performance of the proposed material systems. Conduct ballistic testing on the proposed systems and multiple drop testing at any location on the plate when dropped from a height of at least four feet on to a rigid surface (e.g., concrete, rocks) to demonstrate the feasibility and practicality of the proposed material systems. Deliver a report documenting the research the development efforts along with a detailed description of the proposed material systems and their ballistic performance. Proposed exit criteria – Technology Readiness Level (TRL) 3 – analytical and experimental critical function and proof of concept. PHASE II: Develop the material systems and the processing technology identified in Phase I. Fabricate sufficient samples for extensive ballistic testing. The ballistic testing will include V0 and V50 tests with various small arm rounds, and the back face signatures as well. Deliver a report documenting the material system, material processing and ballistic performance. Proposed exit criteria – TRL 5. Basic technological components are integrated to establish that the pieces will work together in a laboratory environment. PHASE III DUAL USE APPLICATIONS: A new non-ceramic small arm protective insert would be applicable in both military and civilian armor arenas. The civilian law enforcement community would reap a substantial benefit from this effort. Proposed exit criteria – TRL 6. Prototypes demonstrated in a relevant environment.

The process shall eliminate use of sewing to assure that seams are leak-proof and offer the user establishment of safe inner environment and potential for automated assembly process. This proposal would eliminate the current process of sewing and seam heat-taping base fabric material, which is like sewing the end-item twice. The objective is to produce a seam structure with only one-pass through plus to use a seaming process that is compatible with different fabric compositions. DESCRIPTION: New technologies such as laser welding that has been evaluated by the military. The process appears to weld seams extremely fast with different seam configurations and possesses 100 % seam efficiency; whereby the seam is as strong as the base material. This is critically important for high stress applications such as tentage, tarps, weapon covers and air-beams. Any stitchless seaming shall supply hermetically sealed seams for life of end-item. Further research is needed to develop the various aspects of the process and interaction between materials and how end-item pattern pieces can seamed together and be fed into an activation zone in order to produce either straight or three-dimensional seams. Previous research using ultrasonics, extruded adhesive seaming, seam taping and heat welding processes have been a technical challenge and disappointing in not being able to bond dissimilar materials together. Plus such technologies possess low seam strengths and are not durable. PHASE I: Phase I will consist of researching into development of prototype stitchless equipment and conducting an application study into capabilities of seaming textiles with a stitchless process with an array of military materials and seam types. Materials include lightweight Nylon Taslan fabric with breathable film backing, Vinyl coated polyester tentage/tarp fabric, lightweight charcoal activated scrim fabric for CP liner, nylon/cotton water-repellent treated outer CP fabric, breathable coated nylon rain-suit fabric, Kevlar ballistic fabric, lightweight nylon rip-stop parachute fabric, urethane coated air-beam/ water-proof bag fabric and others. All textile fabric specs and/or fabric samples shall be provided as Government Furnished Materials (GFM). Typical seam constructions used for Military end-items would be ASTM seam types FSf, LSa, SSa, LSb, LSp and others. A goal is to maximize seam constructions, seam cross-wise and peel strength using the proposed stitchless technology as the primary trigger, along with a plan to construct a typical CP Uniform with it's numerous pattern pieces along with typical closures (zippers, hook and loop, etc) and small parts (pockets, plackets, cuffs, collar, etc). PHASE II: Phase II would consist of developing Phase I plan into an actual stitchless seaming machine with thought of incorporating means of reducing labor, increasing automation and maximizing safety aspects of machine. Included shall be off-the-arm considerations for construction of typical trouser leg seams, jacket arm sleeve seams, etc., along with three-dimensional seamed constructions such as crotch seaming. underarm seams, seat seams, etc. Completed stitchless seaming machine shall demonstrate the means to fabricate a typical CP Uniform along with all closures and small parts. Typical sewn bartacks and internal sewn seaming (seaming not externally shown) may be used in final construction. Unit shall demonstrate use of maximized automation processes for pattern piece handling. PHASE III: DUAL USE COMMERCIALIZATION: This new process would impact commercial market in numerous ways. End-items for outdoor market would offer waterproof seams, nuclear, toxic waste and land fill industry would have nuclear/chemically protective seams, leak-proof ground protection, composite industry for potential airplane and glider production, commercial tentage, tarps, ground covers, pool liners etc. Large scale manufacturing of proposed stitchless seaming equipment with automated processes, would counter American demise of textile and composite manufacturing.

A03-181 TITLE: Self-Decontaminating Barrier Material Incorporating Catalytically Reactive Membranes for Individual and Collective Protection on a Chemically/Biologically Contaminated Battlefield TECHNOLOGY AREAS: Chemical/Bio Defense ACQUISITION PROGRAM: PM- NBC Defense Systems OBJECTIVE: Explore thin, lightweight, durable, flexible, self-decontaminating, flame resistant, and low solar loading barrier materials impermeable to liquid, vapor and aerosol chemicals and microorganisms. These lightweight composite barrier materials will be based on the employment of an ultra-thin catalytically reactive barrier. During Phase I a proof of concept will be demonstrated based on the needs/requirements for a collective protection barrier fabric, however individual protection requirements/needs will need to be addressed during Phase II. DESCRIPTION: There is a deficiency in the U.S. Army for a CB resistant material, which is lightweight, flexible, decontaminable and affordable. Only two materials have been approved for procurement for CB resistant shelters. One is a disposable polyethylene/saran material, which is inexpensive and lightweight, however lacks UV and flame resistance, is not decontaminable and only provides limited protection (72 hours). The second is a high performance Kevlarâ/Teflonâ material, which is currently being used for the Chemical Biological Protective Shelter (CBPS) [Mil-Spec LP/P DES 1-94a, 20 Jun 1995]. This multi-laminate material provides excellent chemical and biological protection while being flame and UV resistant. However this material is expensive, bulky, semi-rigid and labor intensive to produce. The availability for a chemical and biological resistant material, which is affordable and can be reusable after a chemical and biological attack, will greatly enhance the effectiveness of the future soldier. There is currently a Defense Technology Objective (DTO) to develop a CB protective electron-spun air-permeable membrane for individual protection suits. The proposed topic will develop an impermeable membrane to liquid, vapor and aerosol agents with the ability to self-decontaminate. This technology will have dual applications to both collective protection shelters as well as certain classes of individual protection suits. PHASE I: Phase I will be a proof of concept, which will demonstrate the technical soundness for a self-decontaminating barrier material. This concept will focus on the needs/requirements of a collective protection barrier fabric. The following tasks will be performed: (1) Investigate lightweight composite barrier fabric which is based on the employment of an ultra-thin catalytically reactive1,2,3,4 barrier material. The investigation will include elastomers and thermoplastics. (5) (2) Identify materials/chemical structures that have physical properties compatible to the strenuous activities that a shelter would experience. (3) Identify factors that would influence the diffusion of chemicals and migration of biological species into and through materials to better develop barrier materials. (6) Molecular permeation model of CB agents through selected polymers will be established using selected computer simulation. (4) Based on tasks 1-3, produce and demonstrate non-optimized self-decontaminating catalytically reactive materials and verify potential through simulant testing. PHASE II: At least two materials (best candidate materials selected in Phase I) will be selected, optimized, assembled into a composite material/fabric system, and tested for a variety of industrial chemicals and CB agents. The ability for the fabric to self-decontaminate via a catalytically reactive membrane will be quantified. The composite materials will be produced and expanded to include the requirements for both collective and individual chemical/biological and environmental protection. These composite material/fabric systems will have different composite structures to address the requirement variance. Novel, low-cost manufacturing techniques to fabricate composite barrier fabric systems will also be investigated. PHASE III: No material is currently in existence that can be proven to be decontaminated in a combat field environment and be safe for reuse after vapor contamination. The proposed material will allow Joint Service Explosive Ordnance Disposal (EOD), Technical Escort Units (TEU), Chemical Activities, Defense Preparedness, Joint Transportable Collective Protection System (JTCOPS)-Block 2, and Future Medical Shelter Systems to field, decontaminate and reuse their individual protective equipment/shelters. This area will also open a new realm of reactive materials for use in civilian and military markets, i.e., formerly utilized defense sites (FUNDS) cleanup operations, civilian emergency responses to chemical incidents (terrorist, or chemical activity/accidental emissions).

A03-182 TITLE: Individual Cooling Element (ICE) for Improved Warfighter Hydration TECHNOLOGY AREAS: Human Systems ACQUISITION PROGRAM: PM-Soldier Systems OBJECTIVE: To develop a low cost, lightweight and safe method for chilling beverages that can be integrated into Objective Force Warrior through the Future Hydration System. DESCRIPTION: The Armed Forces have a need for cold beverages in the field. Hot climates such as the desert and jungle require the soldier to drink over a gallon of water a day (1, 2). Studies have shown that in arid zones when the water is warm, soldiers actually drink less (5, 6, 7, 8). This can lead to dehydration resulting in muscle fatigue, heat stroke or death. Ice can be used to keep beverages cold but getting ice to soldiers is difficult from a logistical standpoint; freezers are large, heavy and usually used to store food, not ice. Ice melts quickly in arid environments, making it hard to transport. Water trailer mounted chillers exist but the current version has shown to be too heavy for the trailer, causing stress fractures in the trailer itself and its use is now intermittent and rare. Even cold water becomes warm, as units disperse and time passes, water in canteens and water-bladders becomes warm and unpalatable and without iodine tablets, must be discarded when water temperatures reach 92°F due to high bacteria counts (3,4). A portable, non-electric, reusable beverage chiller would insure that every soldier has access to a cool beverage that is both palatable and safe. Accordingly, innovative technology is required that will provide a nonelectric, compact device for the warfighter to chill beverages while operating in the field. The Individual Cooling Element (ICE) can be single-use or reusable. One example of an acceptable single-use approach would be a vacuum-sealed pouch containing sorption media, a membrane and a breakable refrigerant capsule. The operator breaks open the capsule by squeezing the pouch and the vacuum causes the refrigerant to vaporize and collect in the adsorption media, thus cooling the surrounding beverage. A reusable approach might be better. An example would again involve a sorption media and a vacuum but it would be a rugged device capable of being stored with a partial vacuum. After the cooling is accomplished, heat is added to the system using a squad stove or a field kitchen oven. This would drive the refrigerant out of the sorption media, back across the membrane and into a sealable chamber. It is desired that the refrigerant be water, but other nontoxic and environmentally safe refrigerants will be considered. Surface modified carbon, zeolites and complex-compounds can be used as sorption media. The device must be capable of chilling 32 ounces of water by 20°F in less than 10 minutes. The device must weigh no more than 4 ounces (2 ounces desired). All components must be safe for incidental contact with water. This technology directly supports all three Force Health Protection pillars outlined in Future Operating Capabilities FOC-11-03 (Global Health and Fitness), and FOC-11-06 (Casualty Prevention) by improving hydration and reducing heat-related injuries.
