Protective devices for managing aerodynamics around dental patients

1. A particulate collecting device to be worn by a dental or orthodontic patient, which comprises:

(a) a pair of vertical flanges, with a first flange configured to be positioned and worn on a right side of a patient's chest and a second flange configured to be positioned and worn on a left side of the patient's chest, wherein the vertical flanges have an inner contour that is curved and configured to aerodynamically funnel air flow away from the patient's face;

(b) a protective sheet located between the vertical flanges;

(c) a particulate matter reservoir that is fluidly coupled to the vertical flanges and configured to receive funneled air, and particulates contained therein, from the vertical flanges; and

(d) a negative air pressure generator, which is fluidly coupled to the particulate matter reservoir and is adapted to produce negative air pressure in a direction from a top area of the vertical flanges and running downwards towards the particulate matter reservoir, wherein the particulate matter reservoir exhibits a funnel shape with a flat base that is configured to rest on the patient's chest.

2. The particulate collecting device of claim 1 , which further comprises a hole or recessed area that is adapted to surround the patient's head, wherein the hole or recessed area exhibits a dimension that matches, or substantially matches, contours of a patient's neck, lower jaw, and facial regions.

3. The particulate collecting device of claim 1 , wherein the device is configured to rest on the patient's shoulders.

4. The particulate collecting device of claim 1 , which further comprises a mechanical means for securing the device around the patient's head.

5. The particulate collecting device of claim 1 , wherein the vertical flanges may be adjusted to exhibit a desired length.

6. The particulate collecting device of claim 1 , wherein the vertical flanges may be adjusted to exhibit a desired length by trimming or folding each of the vertical flanges.

7. The particulate collecting device of claim 1 , which further comprises one or more perforations, which are configured to be attached to clips, strings, chains, dental appliances, or combinations of the foregoing.

8. The particulate collecting device of claim 7 , wherein the one or more perforations are further configured to secure the particulate matter reservoir to a desired location on the particulate collecting device.

9. The particulate collecting device of claim 1 , wherein the device consists of, or consists essentially of, a disposable material selected from the group consisting of paper, wood products, recyclable plastic, and combinations of the foregoing materials.

10. A particulate collecting device to be worn by a dental or orthodontic patient, which comprises:

(a) a pair of vertical flanges, with a first flange configured to be positioned and worn on a right side of a patient's chest and a second flange configured to be positioned and worn on a left side of the patient's chest, wherein the vertical flanges have an inner contour that is curved and configured to aerodynamically funnel air flow away from the patient's face;

(b) a protective sheet located between the vertical flanges;

(c) a particulate matter reservoir that is fluidly coupled to the vertical flanges and configured to receive funneled air, and particulates contained therein, from the vertical flanges; and

(d) a negative air pressure generator, which is fluidly coupled to the particulate matter reservoir and is adapted to produce negative air pressure in a direction from a top area of the vertical flanges and running downwards towards the particulate matter reservoir, wherein the particulate matter reservoir exhibits a funnel shape with a flat base that is configured to rest on the patient's chest.

11. The particulate collecting device of claim 10 , which further comprises a hole or recessed area that is adapted to surround the patient's head, wherein the hole or recessed area exhibits a dimension that matches, or substantially matches, contours of a patient's neck, lower jaw, and facial regions.

12. The particulate collecting device of claim 11 , wherein the device is configured to rest on the patient's shoulders.

13. The particulate collecting device of claim 12 , which further comprises a mechanical means for securing the device around the patient's head.

14. The particulate collecting device of claim 13 , wherein the vertical flanges may be adjusted to exhibit a desired length.

15. The particulate collecting device of claim 14 , wherein the vertical flanges may be adjusted to exhibit a desired length by trimming or folding each of the vertical flanges.

16. The particulate collecting device of claim 15 , which further comprises one or more perforations, which are configured to be attached to clips, strings, chains, dental appliances, or combinations of the foregoing.

17. The particulate collecting device of claim 16 , wherein the one or more perforations are further configured to secure the particulate matter reservoir to a desired location on the particulate collecting device.

18. The particulate collecting device of claim 17 , wherein the device consists of, or consists essentially of, a disposable material.

19. The particulate collecting device of claim 18 , wherein the disposable material is paper, wood products, recyclable plastic, or combinations of the foregoing materials.
