Protective masks are currently used by the military and civilian entities for protection against chemical and biological contaminants. However, such masks often impose a substantial physiological burden on the wearer. These masks are typically difficult to wear for prolonged periods because they are relatively bulky and heavy, have high breathing resistance, impair vision and communications, cause thermal stress, physical discomfort, and degrade job performance. Furthermore, the demands placed on such protective masks for use by the crews of military vehicles, such as land and sea vehicles and aircraft, are even greater due to the limitations on the size or bulk of such masks in crowded spaces, the need to avoid fogging of the lenses, and wearer exhaustion from heat buildup, physical discomfort, and respiratory effort.
An improvement over the current design is offered by Army scientists and engineers in a modular helmet-mask assembly which includes a helmet, a face protection assembly, and a transparent, impact resistant lens. The face protection assembly, which can be attached and detached from the helmet, includes a shell which is made of an impact resistant material, for protecting the head and face of the user. The face protection assembly includes a flexible nose cup assembly within the shell and flexible face seal on an inner surface of the shell. The nose cup is positioned to fully engage the mouth and nose of the user, and it includes a breathe-through airflow assembly and filter unit. A strap is attached to the shell or face seal, for adjustably securing the face seal and nose cup to the user’s face to maximize comfort and protection while preventing fogging of the lens.
This design could offer an improvement over the Army M42, M45, M48, M49 masks as well as the Air Force AERP mask system.
- Protection against chemical or biological toxic agents
- Optimized for minimal bulk and weight
- Provides a sufficient flow of purified air for enhancing respiration and comfort, while minimizing lens fogging, heat stress, respiratory effort, and excessive pressure caused by the mask seals on contacted parts of the user's face and head
- Entrepreneurs can acquire the technology for commercialization by licensing the intellectual property in US patent 7,934,497
