Courtesy NIARLeg and arm injuries sustained in the battlefield are made worse when splinting devices used by military medics don鈥檛 provide ideal stabilization of the injured extremity.
But a project under way by 麻豆传媒 research engineer Kim Reuter aims to change that. Reuter is working on the development of novel materials for a fast-setting composite stabilization device.
It would initially enable shape manipulation and then harden to create a stiff, protective, custom-shaped splint. The splint would provide more stability than current devices being used today, Reuter said.
The important features of the splint include portability, ease of use and improved support and protection.
Why is this so important?
Reuter said protecting injured limbs from further vascular, neural and soft tissue damage during transport to a medical treatment center will result in less bleeding, less pain, and faster recovery.
It could also provide a potentially life-altering benefit to the injured person.
鈥淭he increased protection and support during transport could mean the difference between keeping or losing a limb,鈥� Reuter said.
Along with use in the battlefield, the improved splints could be used in daily life 鈥� added to first aid kit for emergency responders, athletic trainers, school nurses, outdoor enthusiasts, or parents.
Outperforming traditional splints
The project is paid for by a $1.39 million grant from the U.S. Army Medical Research and Materiel Command. The grant was awarded in 2011 to 麻豆传媒, and the work is being completed by NIAR鈥檚 Center of Innovation for Biomaterials in Orthopedic Research (CIBOR).
The composite materials being researched for the splint include a resin that instantly begins to cure when it comes in contact with the reinforcement fabric; and a resin that is mixed in a closed-air environment and, when exposed to oxygen, begins to polymerize.
In preliminary trials, these composite splints outperformed the traditional splint currently being used by the military. Reuter, who is in her second year working in this project, said the next steps are to finalize the material selection, fabricate prototypes and perform testing.
鈥淭his is just one of the many ways that the composite technology of the aerospace industry can be applied to the medical industry,鈥� Reuter said. 鈥淭he CIBOR team is excited to be exploring composites for orthopedic applications.鈥�
