Abstract

Surgical helmet assemblies have a helmet enclosure shaped to encircle a head of a user. The helmet enclosure retains a fan and includes a brow bar portion at a front of the helmet enclosure that is shaped to extend along a brow or a forehead of the user and having a light positioned therein. The helmet enclosure also includes a stabilizer extending downward from the helmet enclosure in front of the ears of a user, a face shield that is transparent and coupleable to at least the brow bar portion, a headband shaped to extend across an occiput region of the user's head, and a surgical garment for covering at least the head and shoulders of a user in use. The brow bar portion includes vents disposed therein to direct airflow pushed through the helmet enclosure from the fan onto the user. The face shield is coupleable to the helmet enclosure by one or more of a hook and loop fastener on the helmet enclosure or the stabilizer and a post protruding from the brow bar portion.

Claims (41)

1. A surgical helmet assembly, comprising:

a helmet enclosure shaped to encircle a head of a user including;

a brow bar portion at a front of the helmet enclosure that is shaped to extend along a brow or a forehead of the user; and

first and second stabilizers shaped to extend downward from the helmet enclosure in front of ears of the user, each of the first and second stabilizers comprising a protrusion extending from the brow bar that terminates along a side of the head of the user;

a fan retained in the helmet enclosure;

a face shield that is transparent and coupleable to at least the brow bar portion by one or more of a hook and loop fastener and a post protruding from the brow bar portion;

a headband shaped to extend across an occiput region of the user's head coupled to the helmet enclosure; and

a surgical garment coupleable to the helmet enclosure for covering at least the head and shoulders of a user in use,

wherein the brow bar portion has vents disposed therein to direct airflow pushed through the helmet enclosure from the fan onto the user.

2. The surgical helmet assembly of claim 1 , further comprising a light coupled to the brow bar portion.

3. The surgical helmet assembly of claim 1 , further comprising a light integrated into the brow bar portion.

4. The surgical helmet assembly of claim 1 , wherein the light emitter is connected to a light source via a light pipe, wherein the light source comprises a light-emitting diode located within an interior of the helmet enclosure remote from the light emitter.

5. The surgical helmet assembly of claim 1 , wherein the headband is adjustable and comprises a knob operable to selectively adjust the headband, the knob located to be above the head of the user.

6. The surgical helmet assembly of claim 1 , wherein the face shield comprises a fluid-repelling coating applied thereto.

7. The surgical helmet assembly of claim 1 , wherein the first and second stabilizers comprise vents disposed therein to direct airflow pushed through the helmet enclosure from the fan onto the user.

8. The surgical helmet assembly of claim 1 , wherein the fan comprises a blade fan.

9. The surgical helmet assembly of claim 1 , wherein the fan comprises an air multiplier comprising blades driven by a brushless motor.

10. The surgical helmet assembly of claim 1 , wherein the surgical garment comprises Association for the Advancement of Medical Instrumentation (AAMI) level 4 fabric in critical areas and breathable AAMI level 2 fabric in non-critical areas.

11. The surgical helmet assembly of claim 1 , wherein the surgical garment further comprises a pair of sleeves comprising a breathable fabric having a non-slip film applied thereto.

12. The surgical helmet assembly of claim 1 , wherein the surgical garment comprises a perforated section at the bottom to enable customization of a length of the surgical garment.

13. A surgical helmet assembly, comprising:

a helmet enclosure shaped to encircle a head of a user comprising a brow bar portion at a front of the helmet enclosure that is shaped to extend along a brow or a forehead of the user, first and second stabilizers shaped to extend downward from the helmet enclosure in front of ears of the user, each of the first and second stabilizers comprising a protrusion extending from the brow bar that terminates along a side of the head of the user; and a fan retained in the helmet enclosure, and the helmet enclosure defining at least one conduit in fluidic communication with the fan and vents disposed in the brow bar portion;

a face shield that is transparent and coupleable to at least the brow bar portion by one or more of a hook and loop fastener and a post protruding from the brow bar portion;

a headband shaped to extend across an occiput region of the user's head, the headband coupleable to the helmet enclosure;

a light emitter disposed in the brow bar so as to be located proximate a center of the forehead of the user; and

a surgical garment coupleable to the helmet enclosure for covering at least the head and shoulders of a user in use,

wherein the vents disposed in the brow bar portion direct airflow pushed through the at least one conduit in helmet enclosure from the fan onto the user.

14. The surgical helmet assembly of claim 13 , wherein the first and second stabilizers comprise vents disposed therein to direct airflow pushed through the at least one conduit in the helmet enclosure from the fan onto the user.

15. The surgical helmet assembly of claim 13 , wherein the fan comprises an air multiplier.

16. The surgical helmet assembly of claim 15 , wherein the air multiplier comprises blades driven by a brushless motor.

17. The surgical helmet assembly of claim 13 , wherein the surgical garment comprises Association for the Advancement of Medical Instrumentation (AAMI) level 4 fabric in critical areas and breathable AAMI level 2 fabric in non-critical areas.

18. The surgical helmet assembly of claim 1 , wherein terminal ends of the first and second stabilizers are blunt.

19. The surgical helmet assembly of claim 1 , wherein terminal ends of the first and second stabilizers do not contact each other.

20. A surgical helmet assembly, comprising:

a helmet enclosure shaped to encircle a head of a user including:

a brow bar portion at a front of the helmet enclosure that is shaped to extend along a brow or a forehead of the user; and

first and second stabilizers shaped to extend downward from the helmet enclosure in front of ears of the user, each of the first and second stabilizers comprising a protrusion extending from the brow bar that terminates along a side of the head of the user;

a fan retained in the helmet enclosure;

a headband shaped to extend across an occiput region of the user's head coupled to the helmet enclosure; and

a light emitter enclosed in the brow bar portion so as to be located proximate the forehead of the user;

wherein the brow bar portion has vents disposed therein to direct airflow pushed through the helmet enclosure from the fan onto the user.
