Wound Therapy Machines

Wound Therapy Machines

Negative pressure wound therapy machines provide positive air pressure to a sealed wound to assist in healing. They are typically portable and the pressure cycles on & off at around 125 mm hg. Pressure sensors are used to maintain the pressure level as well as to alert the user if the pressure is too low or too high.
