## Abstract

A pathogen containment system for use during healthcare procedures is disclosed, comprising a flexible tubing dimensioned to extend around a user's mouth, the flexible tubing including a first end and a second end. A connector includes a central portion including a first side fittingly engaged with the first end of the flexible tubing and a second side fittingly engaged with the second end of the flexible tubing. An attachment port is positioned perpendicular to the central portion, the attachment port is in fluid communication via a vacuum tubing to a vacuum suction unit. A plurality of intake ports are provided on the flexible tubing to permit air to be drawn therethrough via the vacuum suction unit. The air intake ports capture a contaminant emitted from the user's mouth or the user's nose.

## Claims

a plurality of air intake ports provided on the flexible tubing to permit air to be drawn therethrough via the vacuum suction unit, the air intake ports to capture a contaminant emitted from the user's mouth or the user's nose;
wherein the flexible tubing and the connector form a loop dimensioned to extend around a user's mouth when the first side of the connector is fittingly engaged with the first end of the flexible tubing and the second side of the connector is fittingly engaged with the second end of the flexible tubing.

### Claim 2 (depends on 1)

The pathogen containment system of claim 1, further comprising at least one pad positioned on a back side of the flexible tubing.

### Claim 3 (depends on 1)

The pathogen containment system of claim 1, wherein the at least one pad includes an adhesive to adhere the pad to the user's skin.

### Claim 4 (depends on 1)

The pathogen containment system of claim 1, further comprising a strap including a first end having a first retainer and a second end having a second retainer, each attached to the flexible tubing, wherein the strap extends around the user's head.

### Claim 5 (depends on 1)

The pathogen containment system of claim 1, further comprising a saliva ejection port positioned on the connector.

### Claim 6 (depends on 5)
