Abstract

Implementations described herein include surgical helmet assemblies that 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.

First claim

What is claimed is:

1. A surgical helmet assembly, comprising:
a shoulder enclosure shaped to be positionable on shoulders of a user, the shoulder enclosure comprising:
a neck portion configured to extend along a posterior side of a base of a neck of the user at or above a level of the shoulders of the user:
first and second shoulder potions extending from the neck portion to extend along the shoulders of the user; and
an air duct extending through the neck portion, the first shoulder portion and the second shoulder portion;

a fan retained in the shoulder enclosure so as to have weight of the fan supported by the shoulders of the user;
a face shield that is transparent and coupleable to the surgical helmet assembly; and
a surgical garment coupleable to the shoulder enclosure for covering at least the head and shoulders of the user in use,
wherein the shoulder enclosure has vents disposed therein to direct airflow pushed through the shoulder enclosure from the fan onto the user.

2. The surgical helmet assembly of claim 1 , further comprising a headband shaped to extend around the user's head.

3. The surgical helmet assembly of claim 2 , wherein the headband supports an auxiliary device.

4. The surgical helmet assembly of claim 3 , wherein the auxiliary device comprises a lighting source.

5. The surgical helmet assembly of claim 2 , wherein the headband is adjustable.

6. The surgical helmet assembly of claim 5 , wherein the headband comprises an elastic strap.

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

8. The surgical helmet assembly of claim 1 , wherein the face shield is pivotable at the shoulder enclosure.

9. The surgical helmet assembly of claim 1 , wherein the face shieled is detachable from the shoulder enclosure.

10. The surgical helmet assembly of claim 1 , wherein the shoulder enclosure comprises:
a horizontally extending portion of the neck portion that connects the first and second shoulder portions;
a shoulder portion configured to extend along an anterior side of a base of a neck of the user, the shoulder portion fluidly connected to the air duct: and
an air intake disposed in the neck portion; and
an air outlet positioned to direct air onto the head of the user.

11. The surgical helmet assembly of claim 10 , wherein the air outlet is positioned on the neck portion to discharge air onto the neck of the user.

12. The surgical helmet assembly of claim 10 , wherein the air outlet is positioned on at least one of the first and second shoulder portions to discharge air onto the face of the user.

13. The surgical helmet assembly of claim 10 , further comprising a discharge duct extending from the shoulder harness to the head of the user, wherein the air outlet is positioned on the discharge duct to deliver cooling air to a superior portion of the head of the user.

14. The surgical helmet assembly of claim 4 , further comprising:
a wire extending from the shoulder enclosure to the lighting source;
a control element connected to at least one of the first and second shoulder portions to operate the fan and the lighting source; and
a power input supported by the neck portion.

15. A surgical helmet assembly, comprising:
a face shield;
a support element for supporting the face shield on a user;
a support structure comprising a shoulder harness and a duct for routing cooling air into or through the shoulder harness; and
a fan mounted to the support structure and configured to deliver cooling air to the duct, wherein weight of the fan is supported by the shoulders of the user.

16. The surgical helmet assembly of claim 15 , wherein the support element comprises a pivot joint connected to the shoulder harness.

17. The surgical helmet assembly of claim 15 , wherein the support element comprises a head band.

18. A surgical helmet assembly, comprising:
a shoulder harness comprising:
a neck portion configured to extend along a posterior side of a base of a neck of the user,
first and second shoulder potions extending from the neck portion to extend along shoulders of the user,
an air intake disposed in the neck portion; and
an air outlet positioned to direct air onto the head of the user;
wherein an air passage extends through the neck portion, the first shoulder portion and the second shoulder portion;

a first fan mounted to the shoulder harness to move air from the air intake through the air passage and to the air outlet,
a second fan supported by the surgical helmet assembly to move air toward the user; and
a control element mounted to shoulder harness to control operation of the fan.

19. The surgical helmet assembly of claim 18 , further comprising:
a face shield; and
a chest portion of the shoulder harness connecting the first and second shoulder portions such that the fluid passage forms a ring extending through the chest portion, the first and second shoulder portions and the neck portion;
wherein weight of the first fan and the second fan is supported by the shoulders of the user.

20. The surgical helmet assembly of claim 1 , wherein the shoulder enclosure comprises:
an air intake fan disposed in the neck portion, and
an air outtake fan disposed in the neck portion;
wherein the fan retained in the shoulder enclosure comprises one of the air intake fan and the air outtake fan.
