| Abstract: |
An air harness in the form of a belt and a pair of suspenders is made of flexible multi-apertured tubing. Ends of the tubing are coupled to a connector positioned behind the wearer and having a rearwardly projecting main vacuum duct that connects to a vacuum hose. The harness and connector are positioned entirely beneath the surgical gown and may be either separable or inseparable therefrom. Air is drawn into the gown and, together with particles shed from the wearer's body, is drawn into the harness tubing for disposal at a remote location. An oronasal vacuum aspirator worn under or formed as a part of a surgical mask is connected to the rearwardly extending vacuum duct. Particles of bacteria and moisture exhaled or shed from the wearer, both in the vicinity of his head and in the vicinity of his torso, are collected by the vacuum system for remote disposal.

I claim:
1. In combination
- a fiexible surgical mask having a sheet of air permeable material adapted to be secured to and over the face of the wearer and having securing ties connected thereto, and
- ducting formed in and constituting an inseparable part of said mask, said ducting comprising a pair of vacuum intake ports at the inside of said mask, each said port comprising
- a flattened, hollow substantially triangular body having a connecting neck that extends rearwardly beyond a rear edge of said mask when the mask is positioned upon the head of the wearer, said body diverging outwardly from said connecting neck to form a relatively narrow elongated mouth, whereby when said mask is secured to the head of the wearer and said connecting neck is coupled to a source of negative pressure, air is drawn through the mask to facilitate breathing of the wearer and exhalations of the wearer are exhausted through the port to the source of negative pressure.
