| 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.

First Claim:
Show all 3 claims |
Having thus set forth a preferred embodiment of the present invention, what is claimed is:
1. A surgical mask to reduce the possibility of iatrogenic and nosocomial disease transmitted by a wearer of the mask, said mask comprising:
- means for securing said mask to the face of a wearer;
- top and bottom layers of air permeable material;
- rupturable container means located between said top and bottom layers and having a plurality of fluid reservoirs in which respective supplies of anti-bacterial fluid are contained, said container means adapted to rupture upon the application of a predetermined minimum force to expulse said anti-bacterial fluid from said plurality of fluid reservoirs;
- an absorbent material located between said top and bottom layers to surround said container means for absorbing and dispensing said anti-bacterial fluid from said fluid reservoirs when said container means is ruptured and said fluid is expulsed; and
- fluid channel means extending from respective ones of said fluid reservoirs for evenly distributing said anti-bacterial fluid throughout said absorbent material when said container means is ruptured and said fluid is expulsed.
