Abstract
A negative pressure dressing assembly includes a drape including an aperture, a cover assembly selectively sealing the aperture in an air-tight manner, a reactor configured to react with a selected gas, and a sealing liner that forms a breakable seal that prevents the reactor from being exposed to the selected gas. The drape is applied to skin to form an enclosed volume between the drape and the skin. The reactor is configured to be activated by breaking the seal, and to be put into fluid communication with the enclosed volume to consume the selected gas from the enclosed volume to create a negative pressure in the enclosed volume.
