CHEMICAL PUMP HOUSING FOR NEGATIVE PRESSURE SYSTEM

Abstract

A chemical pump assembly and method useful for negative pressure therapy includes a chemical pump housing having an inner chamber and a reactor located within the inner chamber being 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. An opening is provided in the chemical pump housing that is in fluid communication with the inner chamber. A cover is disposed over at least a portion of the chemical pump housing for sealing the opening to prevent ingress of air through the opening into the inner chamber after activation of the reactor. The cover includes a cover body having an underside surface facing the chemical pump housing. The underside surface has an adhesive thereon for affixing the underside surface to the chemical pump housing a removable liner disposed over the adhesive on the underside surface, the removable liner including a pull tab extending laterally away from the chemical pump housing.
