MEDICAL AIR PURIFYING RESPIRATOR
AWARD: BRONZE Industrial Design Excellence Award 1995 an annual product design competition sponsored by The Industrial Designers Society of America and Business Week Magazine
Medical Air Purifying Respirator for the Healthcare Environment. “An investigation into the problems associated with providing personal respiratory protection in healthcare and the development of a proposed design solution.” Prepared by Mr. Willis Whiteside – Masters Student (’93-’95) Georgia Institute of Technology (Georgia Tech) – School of Industrial Design
This Industrial Design – product development masters thesis design project involved development of a lightweight, battery powered, positive pressure, loose fitting respirator, that uses a high-efficiency particulate air filter. TB is an airborne disease which can spread through the air by coughing or sneezing viable tuberculin bacilli which become aerosolized as droplets and may remain airborne for hours. Healthcare workers who work in close proximity are exposed to infectious TB. Providing medical air purifying respirator protection from airborne infectious disease, such as TB is a continuing serious and growing problem. The threat of a TB epidemic has been intensified by the mutation of strains of multidrug-resistant TB which does not respond to current drug treatment therapies, resulting in a 60% cure rate.1. NIOSH had made proposals for requires use of a full powered (battery) air purifying respirator (PAPR), equipped with an high efficiency particulate air (HEPA filter , recommended over a negative pressure dust or fume masks. The issue was those mask typically meant for mining, industrial and fire respiratory protection were big and black and bulky, including giving the appearance of a firefighter versus a caretaker of someone who is dying.
The real world problem exists in that the alternative protection devices including paper and HEPA filter masks, although meeting most technical requirements, fail to address important safety, comfort, occupational issues related to the care of infectious TB patients. The thesis reviewed the problems associated with controlling the spread of TB and other airborne diseases to develop a better healthcare provider solution.
The final product design semantic appearance is symbolic of the angelic “halo” and considers the physical, human factors, psychological and social aspects of the patient-caretaker relationship. It included a 105 page written thesis including supervision by 3 thesis advisors.

Medical product development is pure Industrial Design solving human factors problems on many levels. From pencil thumbnail sketches to 3D CAD color renderings the design process is about visualizing the possible solutions or design to meet the physical requirements. Industrial design embraces semantics and keep it simple with the use of figure ground presentations, 3D CAD, product engineering and rapid prototyping. The 3D CAD – shop drawings with all the dimensions needed is the key to working from paper to fully assembled prototype. The team has invested in a rapid printed prototype shop to complement the full prototype shop. New materials and production technologies are used to meet the product materials and performance demands. Our Designers look for the highest quality possible with sincere commitment to performance and human factors friendly solutions that compliments the environment. WhiteLight Design uses industrial design and product design engineering to create efficient and elegant product design and manufacturing solutions. From plastic to metal to aluminum to titanium, metal to plastic conversion our engineers work to model up the invention from the patent. If you and company are looking for product design give the shop a ring.
