Appl.No PCT/US2021/025818 Applicant ZONIT STRUCTURED SOLUTIONS, LLC Inventor PACHOUD, William
The invention addresses the problem of air filtration and decontamination as required immediately for the COVID-19 pandemic but also will be useful in a variety of applications. Air (1) to the apparatus (100) enters and passes through an optional pre-filter (2) and through a one- way air "check" valve (3). The incoming air (1) then enters the counter-flow heat exchange path (4) and proceeds towards the heating chamber (6). As air enters the heating chamber (6), it immediately encounters heating elements (7). Upon encountering the heating chamber (6), the incoming air, which has been pre-heated by the exiting air, is heated to the desired temperature and exits via the return path (5). Upon completing the path through the exit path for the air, the air is now cooled to the desired exit temperature, for example within a few degrees of the incoming air, and is at a temperature suitable to exit (11) and be delivered to a user. This air may not have the virus removed from it, but the virus will be rendered harmless at this point. The invention is applicable in other contexts. For example, the operation of these systems can generally be reversed to decontaminate air including air exhaled by a user. This may be used in conjunction with a mask worn by a patient or an isolation chamber at least partially enclosing a patient, e.g., a patient room(s) or a tent erected over a patient gurney or bed.

The present invention relates to a protective face mask and filtration article, a method for using a protective face mask and filtration article, and a design for manufacturing. In particular, the invention relates to a self-contained, mobile, battery-powered bioactive and filtering breathing appliance that provides broad spectrum antimicrobial and allergic protection via an atomized biocidal agent steam/vapor and a torturous hydrophilic filtration article that sterilizes incoming air and captures debris. To this end, antimicrobial activity and filtration functions leverage a redundancy of means/methods comprised of antimicrobial hydrogen peroxide liquid/vapor/steam and an iodized salt containing hydrophilic filtration article. The present invention is a wearable apparatus that sterilizes incoming air by capturing, neutralizing and destroying airborne pathogens and other particulate matter and pumps sterilized oxygen/air for natural, unlabored breathing by the wearer. The present invention further relates to a production method thereof.

A respirator mask for automatically activating an air-saver switch within a regulator by rotation of the regular as the regulator is mounted and dismounted from a facepiece of the mask. The mask includes a facepiece including a regulator engagement region having an aperture and a protrusion proximate the aperture, and a regulator including a regulator body having a facepiece engagement region matably engageable with the regulator engagement region, a fluid flow path within the regulator body, and a latch within the regulator body, the latch causing obstruction of the fluid flow path when actuated. The latch is engageable with the protrusion, the regulator being rotatable within the facepiece aperture between a first rotational position and a second rotational position, rotation of the regulator within the facepiece aperture from the second to the first rotational position engaging and actuating the latch to obstruct the fluid flow path.

A full-cover face filter mask includes a mask body presenting the outline of the face of the human body and having a cavity large enough to accommodate the face of the human body and an air inlet and an air outlet in communication with the cavity, and a splice frame made of a soft material and set to the mask body along the edge of the cavity. When the mask body is placed on the face of the human body, the face of the human body is fully contained in the cavity and the splice frame closely fits around the face of the human body, so that the mask body isolates the human body face and the external environment to prohibit the external air pollutants, viruses, etc. from touching the human face, avoiding infection of the human body and preventing disease.

A portable, personal protective (PPP) respirator includes a protective barrier made of pliable material that expands when air flow is provided to create a volumetric interior air space, the barrier being non-porous and configured with an opening at one end and sealed at all other surfaces. The PPP respirator includes a barrier collar that is bendable to conform to being worn over a neck and shoulders of a person, the barrier collar providing an attachment component around which material from the open end of the barrier is wrapped to hold the protective barrier in place when the barrier collar is worn around the neck of the person. The PPP respirator includes a mantle having a neck opening for placing of the mantle over the person's head, the mantle resting on the person's neck and shoulders and upper torso when worn. The protective barrier prevents direct exposure to an exterior environment.
