Medical/surgical personal protection system including a light assembly arranged so that heat generated by the assembly is exhausted away from the assembly

A personal protection system comprising:

• a helmet to be worn over the head of a wearer, said helmet including a head band that is disposed above the face of the wearer;
• a hood disposed over said helmet, said hood having a transparent face shield that is forward of said head band;
• a fastening assembly integral with at least one of said helmet or said hood for releasably holding said hood, including said face shield, over said helmet;
• a ventilation assembly integral with said helmet, the ventilation assembly having a fan and a front nozzle that is connected to said fan to receive air output by said fan, said front nozzle having an opening through which the air is discharged that is located forward of the head band so as to be in front of the face of the wearer;
• a light assembly including a light source and a light emitting head, said light assembly being pivotally mounted to said helmet and positioned to emit light through said face shield and being located below the front nozzle opening so that air discharged through the front nozzle opening flows over said light assembly;
• and
• a control arm connected to said light assembly for pivoting said light assembly.

A personal protection system comprising:

• a head band shaped to be worn around the head of a wearer, said head band having a front section worn above the face of the wearer and a rear section opposite the front section;
• a front nozzle attached to said head band so as to be located forward of said head band front section, said front nozzle having an opening;
• a ventilation assembly located above said head band, said ventilation assembly including:
• a shell;
• and a fan disposed in said shell for drawing air into said shell;
• a first support that extends upwardly from said head band to said ventilation assembly shell for supporting said shell above the head of the wearer, said first support being angularly moveable relative to said head band;
• a fastening assembly integral with said ventilation unit shell and said first support for holding said shell to said first support at a plurality of different locations along said first support so that the position of said shell relative to said front nozzle can be adjusted;
• a front conduit that extends between said shell and said front nozzle, said front conduit being adjustable in at least one of length or angle so that, when the position of said shell relative to said front nozzle is adjusted, said front conduit maintains a connection between said shell and said front nozzle;
• a light assembly including a light source and a light emitting head, said light assembly being mounted to said head band and positioned to emit light through said face shield and being located below said front nozzle opening so that air discharged through said front nozzle opening flows over said light assembly;
• a rear nozzle located adjacent said head band rear section that is connected to said shell to receive and discharge air discharged by said fan;
• and
• at least one fastening member attached to said head band for suspending a hood over said head band, said ventilation assembly and nozzles so that a face shield integral with said hood is disposed forward of said head band front section.
