A multi-purpose protection mask for protecting the human face and head against viruses, bacteria, dust or environmental harsh impacts is presented. It has four elements. A face shield transparent sheet covers comfortably the user's face providing adequate space for freely breathing and wearing glasses. A removable and replaceable filter mask element which is a multi-layer filter piece of a proper material affixed over an opening window in the face shield. A ventilator for draining and filtering the exhalation air and humidity before dumping into the atmosphere and it consists of exhaust fans, suction tubes, suction vents, and exit filters. The ventilator prevents condensation of fogging on the face shield and glasses. Another element is a head cover mask made of a fabric material affixed to the face shield element. Fastener strips means are provided for keeping the face shield comfortable and stable on the wearer's face.

A breathing mask having an elongated body having inhalation and exhalation compartments, each of which having openings and valve members over the openings and filters, and a hood assembly having a hood cover, made of a fabric to cover the top, nape and sides of a wearer's head, a transparent face shield connected to the hood cover, which has an upper portion of sight and a lower portion for breathing; the breathing mask is inserted into a hole inside the face shield and secured to it by means of a seal.

A personal protection system (30,178,290) including a helmet (32,180) to which a garment (102,236) is mounted. The helmet (32,180) includes an electrically powered assembly such as a fan (92,266,268,272). At least one button (120,134,262,264) for regulating operation of the electrically powered assembly (92,266,268,272) is mounted to the face shield (110,240) of the garment (102,236). The helmet (32,180) includes a detector (85) that is connected to and monitors the state of the button (120,134,262,264). When the button (120,134,262,264) is depressed, the detector (85) sends a signal to a controller (88) that regulates the actuation of the electrically powered assembly. The controller (88) then sets the operating state of the assembly (92,266,268,272) so that the assembly (92,266,268,272) operates in the state desired by the individual wearing the personal protection system (30,178,290) based on the depression of the control button (120,134,262,264).

Single-use, disposable helmets, hoods, and helmet/hood assemblies are disclosed. Methods of making and using single-use, disposable helmets, hoods, and helmet/hood assemblies are also disclosed.

A respirator includes a frame, a filter layer, and a face seal member. The frame has an outer side and an inner side. The frame defines an opening therethrough. The filter layer is mounted to the outer side of the frame and covers the opening of the frame. The filter layer is configured to prohibit permeation of aerosol, gas, and/or vapor contaminants therethrough. The face seal member is mounted to the inner side of the frame. The face seal member includes a seal contact area configured to engage a facial surface of a wearer. The face seal member incorporates a phase change material therein. The phase change material is configured to provide localized cooling by absorbing heat emitted by the wearer.

A face frame including features for coupling the surgical garment to a surgical helmet. The face frame (524) comprises a lower beam (528) connected by a pair of posts (526, 527). The posts of the face frame comprise a face frame coupler (552, 554) configured to removably couple the face frame to a surgical helmet.

A respiratory device for covering a head of a wearer can comprise a head engagement element. A hood can define an interior and a rim. The hood can comprise a rim that is configured to bias against the head of the wearer to inhibit air communication therebetween. At least a portion of the hood can be transparent. A hose fitting can be operatively coupled to the hood to provide air therethrough into the interior of the hood. The hood can be configured to be releasably coupled to the head engagement element at a plurality of positions. The plurality of positions can comprise a forward position and a rear position that is spaced from the forward position by at least one inch along an anteroposterior adjustment axis.

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.

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 positioned so that, when the garment is disposed over the helmet, the face shield is located in front of the face of the individual. The garment may includes two fastening features spaced apart from one another for releasably securing the shell to the helmet and a conductor that extends between the two fastening features.
