Abstract

A face frame including features for coupling the surgical garment to a surgical helmet. The face frame (524) comprises a lower beam (528) connected by a pair of posts (526, 527). The posts of the face frame comprise a face frame coupler (552, 554) configured to removably couple the face frame to a surgical helmet.

First claim

1 . A face frame for use with a surgical helmet including a mounting feature, said face frame comprising:
a first post and a second post laterally spaced from one another, each of said first and second posts comprising a first end and a second end; a lower beam extending between the second end of each of said first and second posts; and a face frame coupler, optionally positioned proximate said first end of each of said first and second posts, said face frame coupler configured to removably engage the mounting feature of the surgical helmet to allow for removal of said face frame from the surgical helmet to reduce a weight of the surgical helmet when said face frame is not needed.

2 . The face frame of claim 1 , further comprising:
a first upper beam coupled to and extending proximally from said first end of said first post; a second upper beam coupled to and extending proximally from said first end of said second post; and wherein said face frame coupler is positioned proximate the intersection of said first and second upper beams with said first and second posts.

3 . The face frame of claim 2 , further comprising an upper beam extending between the first end of each of said first and second posts;
wherein said upper beam defines an alignment channel; and wherein said upper beam further comprises a protrusion at least partially disposed in said alignment channel.

4 . The face frame of claim 1 , further comprising a coupling member disposed on at least one of said first post or said second post, said coupling member comprising one of a ferromagnetic material or a magnetic material.

5 . The face frame of claim 2 , further comprising a counterweight disposed on each of said first and second upper beams proximal to said first and second posts.

6 . The face frame of claim 5 , wherein said counterweight comprises a mass and is positioned on each of said first and second upper beams a distance from said first and second posts sufficient to maintain sagittal position of the center of gravity of the surgical helmet when said face frame is coupled to the surgical helmet.

7 . The face frame of claim 5 , wherein said counterweight and each of said first and second upper beams comprise complementary fasteners, said fasteners configured to allow said counterweight may be positioned at various points spaced along a length of said first and second upper beams to manipulate the position of the center of gravity of the surgical helmet when said face frame is coupled to the surgical helmet.

8 . The face frame of claim 1 , wherein each of said first post and said second post further comprises a top member and a bottom member, said bottom member being movably coupled to said top member to provide a variable length of each of said first post and said second post to vary the distance between said lower beam and the surgical helmet.

9 . The face frame of claim 1 , further comprising an upper beam extending between the first end of each of said first and second posts;
wherein each of said first post and said second post further comprises a top member and a bottom member, said bottom member being movably coupled to said top member to provide a variable length of each of said first post and said second post to vary the distance between said lower beam and the surgical helmet; and a protrusion that is removably coupled to said upper beam to allow for said protrusion to be repositioned on said upper beam based on the length of said first post and said second post.

10 . A surgical apparel system comprising:
a surgical helmet comprising:
a mounting feature disposed on a distal portion of said surgical helmet;
a headband for securing said surgical helmet to a wearer; and
a ventilation unit supported by the headband;
a face frame removably coupled to said surgical helmet, said face frame comprising:
a first post and a second post laterally spaced from one another, each of said first and second posts comprising a first end and a second end;
a lower beam extending between the second end of each of said first and second posts;
a first upper bracket coupled to and extending proximally from said first end of said first post;
a second upper bracket coupled to and extending proximally from said first end of said second post; and
a face frame coupler for removably engaging said mounting feature of said surgical helmet; and
a coupling member disposed on said face frame and optionally comprising one of a ferromagnetic material or a magnetic material;

a surgical garment configured to be at least partially disposed over said surgical helmet, said surgical garment comprising:
a fabric defining an opening;
a transparent shield disposed within said opening; and
an attachment element optionally comprising the other of the ferromagnetic material or the magnetic material, said attachment element configured to removably engage said coupling member to couple said surgical garment to said surgical helmet.

11 . The surgical apparel system of claim 10 , wherein said face frame coupler comprises one of a ferromagnetic material or a magnetic material; and
wherein said mounting feature of said surgical helmet comprises the of the ferromagnetic material or the magnetic material.

12 . The surgical apparel system of claim 10 , wherein said face frame further comprises an upper beam having a mounting feature; and
wherein each of said first upper bracket and said second upper bracket comprises a face frame coupler configured to removably engage said mounting feature of said upper beam to removably couple said first post and said second post of said face frame to said upper beam.

13 . The surgical apparel system of claim 10 , wherein said transparent shield further comprises a tab extending from an upper portion of said transparent shield; and
an opening defined by said tab, said opening configured to removably couple said surgical garment with the surgical helmet.

14 . The surgical apparel system of claim 13 , wherein said surgical helmet further comprises an upper beam, said upper beam defining an alignment channel;
a protrusion coupled to said upper beam and at least partially disposed within said alignment channel; and wherein said tab is configured to be at least partially disposed within said alignment channel when said protrusion is inserted within said opening to couple said surgical garment to said surgical helmet.

15 . A surgical garment for use with a surgical helmet including a coupling member, said surgical garment comprising:
a fabric defining an opening; a transparent shield disposed within said opening, said transparent shield comprising: an upper portion and a lower portion; an attachment element coupled to said upper portion of said transparent shield and configured to removably couple with the coupling member of the surgical helmet; and an adjustment device coupled to said lower portion of said transparent shield positionable to vary a curvature of said lower portion of said transparent shield.

16 . The surgical garment of claim 15 , wherein said adjustment device comprises a cylinder including a piston configured to move longitudinally within said cylinder manipulating a distance between a first end and a second end of the adjustment device to vary a curvature of said lower portion of said transparent shield.

17 . The surgical garment of claim 15 , wherein said adjustment device comprises a ratchet and a strap configured to vary a curvature of said lower portion of said transparent shield.

18 . The surgical garment of cla
