Abstract

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system may include a head unit over which surgical garment such as a hood or a toga may be suspended over. The surgical garment may include a sterile material and a shield configured to be disposed in front of the wearers face when disposed over the head unit. The shield may comprise an anti-reflective coating configured to reduce the glare observed by the individual through said shield. The head unit may comprises a light assembly that is disposed on the wearers side of the surgical garment, and an inner surface of said surgical garment may comprise a light reflective material configured to reduce the amount of light emitted from said light assembly that is reflected back toward the individual.

First claim

What is claimed is:

1. A personal protection system comprising:
a surgical garment configured to be at least partially disposed over a head of an individual and define a barrier between the individual and a surrounding environment, said surgical garment comprising:
a material;
and
a shield coupled to the material and forming a portion of said surgical garment, said shield configured to allow the individual to see the surrounding environment through said surgical garment;

a head unit for supporting said surgical garment over the head of the individual, said head unit comprising:
a ventilation unit including a fan, said fan configured to draw air through said surgical garment and circulate the air about the individual wearing said system;

wherein said shield comprises an anti-reflective coating configured to reduce the glare observed by the individual through said shield.

2. The system of claim 1 , wherein said shield further comprises a top, a bottom, and a perimeter section that is covered by a portion of said material.

3. The system of claim 2 , wherein said head unit further comprises a static tab that extends upward; and
said shield further comprises a tab defining a first opening configured to receive said tab of said head unit to removably couple said surgical garment to said head unit.

4. The system of claim 3 , wherein said tab of said shield extends from said perimeter section of said top of said shield.

5. The system of claim 2 , wherein said shield defines a second opening and a third opening positioned on opposing sides of an axis that extends from said top to said bottom of said shield; and
wherein said second opening and said third opening are positioned in said perimeter section of said shield.

6. The system of claim 5 , wherein said second opening and said third opening are configured to removably couple said surgical garment to the head unit.

7. The system of claim 1 , wherein the surgical garment further comprises a filter element coupled to the material and forming a portion of said surgical garment, said filter element configured to filter air passing through surgical garment.

8. The system of claim 1 , wherein the head unit further comprises a face frame configured to support said surgical garment when disposed over said head unit and position the shield forward of the individuals face.

9. The system of claim 8 , wherein said face frame further comprises a mounting member and said shield defines a mounting feature;
wherein said mounting member of said face frame is configured to removably couple with said mounting feature of said shield to removably couple said surgical garment to the head unit.

10. A personal protection system comprising:
a surgical garment configured to be at least partially disposed over a head of an individual and define a barrier between the individual and a surrounding environment, said surgical garment comprising:
a material;
and
a shield coupled to the material and forming a portion of said surgical garment, said shield configured to allow the individual to see the surrounding environment through said surgical garment;

a head unit for supporting said surgical garment over the head of the individual, said head unit comprising:
a ventilation unit including a fan, said fan configured to draw air through said surgical garment and circulate the air about the individual wearing said system;
a light assembly disposed on a wearer's side of the barrier configured to emit light through the shield to assist the individual in observing the surrounding environment;

wherein an inner surface on the wearers side of said surgical garment comprises a light reflective material configured to reduce the amount of light emitted from said light assembly that is reflected back toward the individual.

11. The system of claim 10 , wherein the surgical garment further comprises a filter element coupled to the material and forming a portion of said surgical garment, said filter element configured to filter air passing through surgical garment.

12. The system of claim 10 , wherein the head unit further comprises a face frame configured to support said surgical garment when disposed over said head unit and position the shield forward of the individuals face.

13. The system of claim 12 , wherein said face frame further comprises a mounting member and said shield defines a mounting feature;
wherein said mounting member of said face frame is configured to removably couple with said mounting feature of said shield to removably couple said surgical garment to the head unit.

14. The system of claim 10 , wherein said light assembly includes a light source disposed adjacent to a lens;
wherein said light assembly is configured such that a longitudinal position of said lens may be manipulated relative to said light source to selectively focus and/or diffuse a beam of light emitted from said light assembly.

15. The system of claim 14 , wherein said head unit further comprise a processor in communication with a servo motor; and
wherein said processor is configured generate a control signal to said servo motor to cause said servo motor to manipulate the longitudinal position of said lens to said light source.

16. A surgical garment for use with a head unit and configured to be at least partially disposed over the head unit and an individual wearing the head unit, said surgical garment comprising:
a material to define a barrier between the individual and a surrounding environment;
a filter element coupled to the material and forming a portion of said material, said filter element configured to filter air passing through surgical garment; and
a shield disposed in an opening defined by said material, said shield configured to allow the individual to see the surrounding environment through said surgical garment;
a tab extending from said shield and defining a first opening configured to receive a static tab of the head unit to removably couple said surgical garment to the head unit; and
wherein said shield is coated with an anti-reflective material configured to reduce the glare observed by the individual through said shield.

17. The surgical garment of claim 16 , wherein said shield further comprises a top, a bottom, and a perimeter section that is covered by a portion of said material.

18. The surgical garment of claim 17 , wherein said shield defines a second opening and a third opening positioned on opposing sides of an axis that extends from said top to said bottom of said shield; and
wherein said second opening and said third opening are positioned in said perimeter section of said shield and configured to removably couple said surgical garment to the head unit.

19. The surgical garment of claim 18 , wherein said first, second and third openings are positioned such that a radius of curvature of said shield varies along said axis from the top-to-bottom of said shield when said shield is coupled to the head unit.

20. The surgical garment of claim 16 , wherein said tab of said shield extends from a perimeter section at a top of said shield.
