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 head garment having a base section and a face section is provided where the face section is both affixed to the base section and releasably extends over the face of the user to create a magnetic seal against the elements. The head garment may also include a magnetic fastener to position the face covering section when it is not extended over the face of the user.

A multi-layer visor system for a surgical hood or garment is provided. The system includes a base film layer and one or more removable film layers that are coextruded at high temperature to form a sterile surface between each of the film layers should the surgeon elect to peel away a soiled or splattered removable film layer during the course of a surgical procedure so that an unobstructed view can be maintained. Thus, no separate sterilization step is required in order to sterilize the layers of the visor system. Each of the removable film layers can additionally include a tab having distinctive features in order to enable a wearer to easily distinguish between the tabs in order to make it easier for a wearer to know which tab to pull first to remove the outermost removable film layer. Further, because the tabs are located about the perimeter of the removable films, viewing is not obscured, yet the film layers are held securely in place until easily removed from the underlying removable film layer or base film layer.

A personal protective device (PPE) comprising a face cover assembly and a bodysuit configured to be worn by a human user. The device protects users against airborne aerosol particles containing viruses or other infectious agents while enabling improved flexibility relative to prior art designs. The device includes a helmet-like” rotating face cover assembly that fits over the user's head and attaches to a collar on the biohazard bodysuit. This rotating face cover assembly has a plurality of different mask sides, each with differing geometries or other properties. The device enables a user to rotate (either manually or by electric motor) the masks and select a given mask side that best meets that user's needs. The different mask sides can accommodate different facial geometries, eyewear types, and use cases, such as operation in more hostile environments. Features to improve user comfort, including alternate bodysuit designs, moisture reduction, and cooling are disclosed.

Implementations described herein include surgical helmet assemblies that have a helmet enclosure shaped to encircle a head of a user. The helmet enclosure retains a fan and includes a brow bar portion at a front of the helmet enclosure that is shaped to extend along a brow or a forehead of the user and having a light positioned therein. The helmet enclosure also includes a stabilizer extending downward from the helmet enclosure in front of the ears of a user, a face shield that is transparent and coupleable to at least the brow bar portion, a headband shaped to extend across an occiput region of the user's head, and a surgical garment for covering at least the head and shoulders of a user in use. The brow bar portion includes vents disposed therein to direct airflow pushed through the helmet enclosure from the fan onto the user. The face shield is coupleable to the helmet enclosure by one or more of a hook and loop fastener on the helmet enclosure or the stabilizer and a post protruding from the brow bar portion.

A medical garment for use with a helmet, wherein the garment comprises a shell and a transparent face shield configured to define a barrier between the wearer and the environment. The transparent face shield may comprise a tab configured to be at least partially disposed within an alignment channel of the helmet when the medical garment is attached to the helmet to orient the shell relative to the helmet. The tab may also be separate from the transparent face shield and disposed on the shell of the medical garment. The transparent face shield may also comprise an attachment element configured to removably couple with a coupling member of the helmet, wherein the attachment element and coupling member comprise complementary coupling surfaces.

Embodiments of particle protection headwear apparatuses and use thereof are detailed herein. In general, embodiments of the present invention include a shield and a shroud which couple to, or are partially or wholly integral with, a hat. The shield extends downwardly from the hat and is typically embodied as part of the hat. Further, the shield is designed for a user to be able to look through it. The shroud is coupled to and extends downwardly from the shield and the hat. The shroud extends entirely around a perimeter of the hat to form a breathable barrier between particles and the user's head. The shroud may be removeable from the shield and washable.

A personal protection system including a surgical garment that may be mounted to a helmet including an electrically powered assembly, such as a fan. The garment includes a shell adapted for being disposed over the helmet of the personal protection system. The garment also includes a transparent face shield coupled to the shell and an indicia, the indicia being an optically perceivable marking on the garment. The garment may also include a memory, the memory for storing data for regulating the operation of the electrically powered assembly mounted to the helmet. The helmet may also include a sensor for detecting the indicia to selectively allow the actuation of the electrically powered assembly based on the presence or absence of the indicia being positioned adjacent the sensor.

A barrier system, device, and method protects medical professionals and patients from exposure to contaminants and bodily fluids is provided. The system includes a head unit shaped to be worn over the head of the wearer; a hood positioned over the head unit; one or more sensors configured to produce one or more sensor-output signals; and a controller connected to the one or more sensors and configured to produce one or more controller-output signals based on the one or more sensor-output signals. Further, a device inside a barrier system is controlled by (a) sensing one or more characteristics; (b) producing one or more sensor signals based on the sensed one or more characteristics; (c) converting and/or processing the one or more sensor signals to produce one or more controller-output signals; and (d) controlling the device based on the one or more controller-output signals.

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.
