Surgical helmet assembly with a reconfigurable chin bar
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.
1. A face frame for use with a surgical helmet including a mounting feature comprising one of a ferromagnetic material or a magnetic material, said face frame comprising:
a first post and a second post laterally spaced from one another, each of said first and second posts comprising an upper portion and a lower portion;
a lower beam extending between the lower portion of each of said first and second posts; and
a face frame coupler positioned proximate a first end of each of said first and second posts, said face frame coupler comprising either of the ferromagnetic material or a magnetic material that is capable of removably engaging 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;
an upper beam extending between the upper portion of each of said first and second posts; 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.
2. The face frame of claim 1 , further comprising:
the upper beam coupled to and extending proximally from said upper portion of each of said first post and said second post; and
wherein said face frame coupler is positioned proximate an intersection of said upper beam with said first and second posts.
3. The face frame of claim 2 , further comprising the upper beam extending between the upper portion 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 2 , further comprising a counterweight disposed on a bracket coupled to said upper beam proximal to said first and second posts.
5. The face frame of claim 4 , wherein said counterweight comprises a mass and is positioned on the first and second lateral portions of said upper beam 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.
6. The face frame of claim 4 , wherein said counterweight and each of said first and second lateral portions of said upper beam 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 lateral portions of said upper beam to manipulate the 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 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.
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 a distance between said lower beam and the surgical helmet.
9. 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 a distance between said lower beam and the surgical helmet.
