Abstract
A chemical pump assembly useful for negative pressure therapy includes a chemical pump housing having an inner chamber, a reactor located within the inner chamber, an opening provided in the chemical pump housing, a first pull tab which extends from the inner chamber to ambient through the opening, and a removable layer connected to the first pull tab. The reactor is configured to react with a selected gas found in air so as to consume the selected gas when exposed to air in the inner chamber. The removable layer shields the reactor from air in the inner chamber atmosphere until the removable layer is removed.
