Abstract

A surgical apparel system including a surgical helmet to which a garment may mounted. The surgical helmet includes an electrically powered peripheral device, such as a ventilation assembly, and a headband for removably securing the surgical helmet to the head of a wearer. The headband comprises a rear a portion including opposing ends defining a contact point configured to contact the head of the wearer. The rear portion may also comprise a support member disposed between the opposing ends. The support member may be offset distally from the contact points such that the support member defines a void between the head of the wearer and the headband to allow the hair to collect between the head of the wearer and the support member.

First claim

What is claimed is:

1 . A surgical helmet for use with a surgical garment configured to define a barrier between a wearer and an external environment, the surgical helmet comprising:
a headband including a front portion, a rear portion and a pair of opposed side portions connecting the front portion to the rear portion, the headband configured to encircle a head of the wearer; a ventilation assembly coupled to the headband, the ventilation assembly configured to draw air through the surgical garment and circulate it about the wearer; wherein the rear portion of the headband comprises:
a base member for slidably receiving an end of each of the pair of opposed side portions of the headband;
a pair of separate contact surfaces spaced apart from one another to define a first void therebetween and configured to contact the head of the wearer, each of the pair of contact surfaces is slidably coupled to one of the side portions;
at least one support member disposed between each of the pair of contact surfaces and the base member, the at least one support member configured to offset the contact surface proximally from the base member to define a second void between each of the pair of contact surfaces and the base member of the rear portion of the headband to allow the hair to collect between the head of the wearer and the base member; and
wherein the pair of contact surfaces and the support member are formed as an integral member of the base member of the rear portion of the headband.

2 . The surgical helmet of claim 1 , further comprising a control member disposed on the base member of the rear portion of the headband and configured to alter a circumference of the headband by moving each of the pair of opposed side portions relative to the base member of the rear portion.

3 . The surgical helmet of claim 1 , wherein the combination of the front portion, the rear portion, and the pair of opposed side portions define a continuous headband.

4 . The surgical helmet of claim 1 , wherein the first void is defined laterally between the support member of each of the pair of contact surfaces and the second void is defined sagittally between the base member and each of the pair of contact surfaces.

5 . The surgical helmet of claim 1 , further comprising:
a housing of the surgical helmet, the housing coupled to the headband and configured to at least partially encircle the ventilation assembly; and a head lamp disposed on at least one of the housing of the surgical helmet or the headband and configured to project a beam of light distally in front of the face of the wearer of the surgical helmet.

6 . The surgical helmet of claim 5 , further comprising a bracket coupled to the housing of the surgical helmet and configured to at least partially encircle the head lamp, the bracket shaped to assist with directing the beam of light from the head lamp distally and away from the wearer.

7 . The surgical helmet of claim 5 , further comprising a shroud removably coupled to one of the surgical helmet, the housing of the surgical helmet, or a face frame of the surgical helmet; and
wherein the shroud defines a void configured to partially surround the head lamp, the shroud shaped to assist with directing the beam of light from the head lamp distally and away from the face of the wearer.

8 . The surgical helmet of claim 6 , wherein the shroud comprises a distal edge and opposing proximal edge, the distal edge configured to be positioned adjacent the surgical garment; and
a flexible member extending between the proximal edge of the shroud and a light element of the head lamp, the flexible member configured to move with the head lamp to fill a portion of the void between the proximal edge of the shroud and the housing of the head lamp to prevent beam of light from the head lamp from being directed and/or reflected toward the wearer.

9 . The surgical helmet of claim 8 , further comprising a rocker disposed on the housing of the surgical helmet, the rocker coupled to the housing of the head lamp and manipulatable by the wearer to move the head lamp to direct the beam of light coming from the head lamp.

10 . The surgical helmet of claim 1 , further comprising:
a housing, the housing coupled to the headband and configured to at least partially encircle the ventilation assembly; a strap disposed on the front portion of the headband, the strap comprising at least one front mounting feature; and wherein the housing comprises a plurality of coupling features configured to removably engage the front mounting feature of the front portion of the headband, the plurality of coupling features incrementally spaced along the housing to provide sagittal adjustment of the front portion of the headband relative to the housing.

11 . The surgical helmet of claim 10 , wherein the front mounting feature comprises a post and the plurality of coupling features comprise a plurality of apertures defined in the housing and configured to receive the post and create a friction fit to removably secure the front portion of the headband to the housing.

12 . The surgical helmet of claim 1 , further comprising a housing, the housing coupled to the headband and configured to at least partially encircle the ventilation assembly; and
wherein the second void defined by the rear portion of the housing and the first void defined between the pair of contact surfaces of the rear portion of the headband are aligned vertically and configured to allow the hair of the wearer to collect between the head of the wearer and the base member of the rear portion of the headband without interference from the headband or the housing.

13 . A surgical helmet including an electrically powered assembly, the surgical helmet comprising:
a housing; a headband for supporting the housing above a wearer's head, the headband comprising:
a front portion;
a pair of opposed side portions;
a rear portion connected to the front portion by the pair of opposed side portions, the combination of the front portion, the pair of opposed side portions, and the rear portion of the headband configured to encircle a head of the wearer, the rear portion comprising:
a base member for receiving an end of each of the pair of opposed side portions;
a control member disposed on the base member, the control member configured to extend and retract each of the pair of opposed side portions relative to the base member to alter a circumference of the headband;
a pair of discontinuous contact surfaces positioned on opposed sides of a midline of the headband extending between the front and rear portions and configured to contact the head of the wearer, each of the pair of contact surfaces slidably coupled to one of the side portions; and

a support member disposed between each of the pair of contact surfaces and the base member, the support member configured to space the base member distally away from each of the contact surface defining a void between the pair of contact surfaces and the base member to allow the hair to collect between the head of the wearer and the base member; and
wherein the pair of contact surfaces and the support member are formed as an integral member of the base member of the rear portion of the headband.

14 . The surgical helmet of claim 13 , wherein the void comprises a first void defined laterally between the support member of each of the pair of contact surfaces and a second void defined sagittally between the base member and each of the pair of contact surfaces.

15 . The surgical helmet of claim 13 , further comprising:
a strap disposed on the front portio
