Abstract

An apparatus includes a splash shield incorporating a clear viewing area, a vacuum manifold, the vacuum manifold adapted to releasably engage the splash shield, and a link emanating from the vacuum manifold, the link configured to attach to a vacuum system wherein application of a vacuum creates a laminar flow to draw vapor away from the splash shield.

Claims (15)

1. An apparatus for a dental environment comprising:

a splash shield for positioning between a dental practitioner and a patient, the splash shield incorporating a clear viewing area and having a curved main surface;

a flexible evacuation collar removably affixed along a perimeter of a lower side of the curved main surface of the splash shield; and

a link emanating from the evacuation collar, the link configured to attach to a vacuum system wherein application of a vacuum creates a flow to draw vapor away from the splash shield.

2. The apparatus for a dental environment of claim 1 wherein the vacuum system includes a high-efficiency particulate air (HEPA) and/or ultraviolet (UV) filtration system.

3. The apparatus for a dental environment of claim 1 wherein the splash shield comprises a generally curved main surface with a portion on its perimeter to receive and position the evacuation collar.

4. The apparatus for a dental environment of claim 1 wherein the splash shield is detachable.

5. The apparatus for a dental environment of claim 1 wherein the evacuation collar comprises a flexible tubing.

6. An apparatus for a dental environment comprising:

a splash shield for positioning between a dental practitioner and a patient, the splash shield incorporating a clear viewing area and having a curved main surface;

a vacuum manifold, the vacuum manifold adapted to releasably engage the splash shield; and

a link emanating from the vacuum manifold, the link configured to attach to a vacuum system wherein application of a vacuum creates a laminar flow to draw vapor away from the splash shield.

7. The apparatus for a dental environment of claim 6 wherein the vacuum system includes a high-efficiency particulate air (HEPA) and/or ultraviolet (UV) filtration system.

8. The apparatus for a dental environment of claim 6 wherein the splash shield comprises a generally curved main surface with a surface on its perimeter to receive and position the evacuation collar.

9. The apparatus for a dental environment of claim 6 wherein the splash shield is detachable.
