A surgical protection system to define a barrier between the user and the external environment. The surgical protection system comprising a helmet assembly, a hood and a transparent face shield. The helmet including a shell, a face frame coupled to the shell, a static tab, a first fastener disposed on the face frame; and a fan mounted to the shell and configured to circulate air about the user. The hood may include a first material defining an opening. The shield may be formed from flexible material and disposed within the opening of the hood. The shield may further include a tab extending from a top portion of the shield and define an opening configured to receive the static tab of the helmet to align the shield to the helmet. The first fastener disposed on the face frame may be configured to facilitate removable attachment of the shield to the helmet.

A breathing apparatus and method adjusting air flow in a breathing apparatus are provided. The breathing apparatus comprises: a first face piece for directing a flow of air towards the user's mouth and nostrils; a second face piece for directing exhaled breath away from the user's mouth and nostrils; at least one sensor, coupled to the first or second face piece, for monitoring the user's breathing; a controller that adjusts the flow of air to the first face piece and the extraction of air exhaled by the user through the second face piece based on an output from the at least one sensor.

A personal protection system including a garment configured for attachment to a helmet, wherein the garment defines a barrier between a wearer and an environment. The system includes a control mount integral to the garment and at least partially disposed on the environment side and the wearer side of the barrier. The system may include an emitter and a sensor configured to detect a signal output by the emitter. The control mount may comprise a lens configured to transmit the signal from the emitter through the garment. A control member may be coupled to the control mount and configured to be manipulated by the wearer. When manipulated by the wearer, the control member may distort and/or disrupt the transfer of the signal through the lens that is detected by the sensor. The sensor may provide a sensor input signal based on the signal detected from the emitter.

In some examples, a system includes a head-mounted device, a visor that includes a reflective object that is substantially transparent in a visible light spectrum and embodied at a physical surface of the visor, at least one visor attachment assembly that couples the visor to the head-mounted device; at least one optical sensor; and at least one computing device communicatively coupled to the at least one optical sensor, the at least one computing device comprising a memory and one or more computer processors that: receive, from the optical sensor, an indication of light outside of a visible light spectrum that is reflected from the reflective object; determine, based at least in part on the light outside of a visible light spectrum that is reflected from the reflective object, a position of the visor; and perform, based at least in part on the position of the visor, at least one operation.

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. The helmet has a chin bar that extends forward of the face of the individual wearing the system. At least one manually actuated control for regulating one aspect of operation of the system is mounted to the chin bar. Sometimes the control is a button that is depressed to control the operation of a helmet mounted fan that draws air into the hood or toga. A microphone may also be mounted to the chin bar.

A personal protection system including a support (100) worn around the head and a hood (400) worn over the head and the support. A ventilation unit (150) attached to the support draws air into the hood. Ultraviolet lights (360) direct light into the air stream drawn into the hood. The light renders microorganisms in the air stream innocuous.

A protective apparel support system is disclosed comprising a support frame configured to rest on the shoulders of a wearer, the support having a first shoulder member, a second shoulder member and a shield engagement portion. A shield is selectively coupleable to the support and protective apparel is coupled to the shield.

A powered air purifying respirator (PAPR) for delivering a forced flow of filtered air to a wearer is disclosed. The PAPR comprises a turbo unit with turbo unit components including a fan, an electric motor, and an electronic control unit having a wireless electronic control transceiver, the fan being driven by the electric motor under the control of the electronic control unit and the electronic control unit being configured to send and receive information via the electronic control transceiver; a turbo unit power source that provides power to the turbo unit components; a turbo remote control unit having a wireless turbo remote control transceiver; at least one turbo status indicator unit, adapted to indicate a current operating status of the turbo unit and/or turbo unit components, having a wireless turbo status transceiver; wherein at least one of the turbo remote control unit and turbo status indicator unit is remote from the turbo unit, and wherein at least two of the electronic control transceiver, the turbo remote control transceiver and the turbo status transceiver are in wireless communication with each other.

A respirator assembly has a shell that defines a breathable air space for a user wearing the respirator assembly. The respirator assembly has an air delivery conduit within the shell for providing air to the breathable air space. The air delivery conduit has an air outlet that is either adjustable in configuration or has a vane associated therewith that is adjustable in position so that the direction of the air exiting the air outlet is controllable between first and second air flow directions. The user is able to control the direction of air exiting the air outlet while the respirator assembly is worn by the user.

A method of generating a customized headgear that includes a plurality of physical features and being usable with a mask component that supplies a flow of breathing gas to the patient's airways. The method includes receiving one or more parameters pertaining to the patient's head, subjecting at least some of the parameters to one or more algorithms to determine at least one of a length of a physical feature of the plurality of physical features and an angle between a pair of physical features of the plurality of physical features, generating an outline of at least a portion of a body which, when formed, is usable to assemble therefrom at least a portion of the headgear, and outputting a pattern usable to enable the formation of the at least portion of the body from at least a first sheet of at least a first material.
