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.

Abstract: A waste collection unit including a waste container, and vacuum source to collect medical waste into the waste container. The vacuum source is disposed within a sound attenuating enclosure that defines an enclosure inlet for receiving cooling air and an enclosure outlet for discharging warmed cooling air. The sound attenuating enclosure is at least partially formed of a sound-absorbing material and may define a pocket for receiving a first end of the vacuum source. The first end of the vacuum source may engage a seat of the sound attenuating enclosure to provide a cooling air barrier. The seat may define a bottom portion of the pocket. Internal geometries of the sound attenuating enclosure may be shaped to define another air path that does not pass through the vacuum source. A plenum may be attached to the sound attenuating enclosure and define a plenum chamber to collect the warmed cooling air.

Abstract: A waste collection unit is provided that comprises a vacuum pump and smoke evacuation system including a blower and blower motor. The vacuum pump, the blower, and the blower motor, create noise. This noise is attenuated in first and second sound attenuating enclosures for the vacuum pump and the blower and blower motor. A cleaning system is also provided with rotating liquid delivery devices. An actuator is operatively coupled to the liquid delivery devices to rotate the liquid delivery devices.
