An Airman straps on the multi-channel wound vacuum system during training at the 59th Medical Wing, San Antonio, Texas, Nov. 30, 2016. The multi-channel wound vacuum system, which is used to help promote wound healing on critical patients, is able to replace four single-channel systems. This smaller, more transportable device makes it easier for aeromedical evacuation crews to deliver en route wound care to patients with multiple wounds on the back of an aircraft where space is limited. The Air Force Medical Evaluation Support Activity (AFMESA) team was involved in the development and testing of the multi-channel wound vacuum system, ensuring the device could perform in the operational environment.
