Abstract
A negative pressure wound therapy system creates a negative pressure environment in the opening of a wound-dressing unit and a positive pressure environment in the collecting bag. Then a positive pressure detecting procedure is proceeded in the positive pressure environment and a negative pressure detecting procedure is proceeded in the negative pressure environment. The detecting results are sent to determine whether a micro pump is stopped.
