ABSTRACT:
A disposable surgical mask which reduces the transmission of iatrogenic or nosocomial, viral or bacterial infection by operating room personnel. The mask includes a containment envelope within which is sealed a rupturable membrane (e.g., an ampule) containing an anti-bacterial fluid. A series of breathing apertures are formed in the containment envelope through which the wearer may breathe. In operation, the wearer supplies sufficient force to break the rupturable membrane and thereby release the anti-bacterial fluid therefrom. The wearer then breathes normally through the apertures formed in the containment envelope, so that the potentially infectious bacterial population of the wearer's exhalations will be substantially reduced by the anti-bacterial fluid expulsed from the ruptured membrane.
