A meltblown material formed from a plurality of fibers that can withstand the effects of a gamma irradiation sterilization process without negatively impacting the bacterial filtration efficiency (BFE) and particle filtration efficiency (PFE) of the meltblown material (e.g., facemasks, surgical gowns, surgical caps, etc.) is provided. The fibers include a high melt flow rate (MFR) polyolefin. Further, both the fibers include specific antioxidants and a charge enhancer package that allow for the effective electret treatment of the resulting meltblown material prior to sterilization, where the filtration efficiency and of the material is improved post- sterilization compared to materials without the specific combination of antioxidants and charge enhancing components.

A meltblown material formed from bicomponent fibers that can withstand the effects of a gamma irradiation sterilization process without negatively impacting bacterial filtration, particulate filtration, and/or breathability of personal protective equipment products formed from the meltblown material (e.g., facemasks, surgical gowns, surgical caps, etc.) is provided. The bicomponent fibers include a polyester-based sheath and a polyolefin- based core. Further, both the sheath and core include specific antioxidants and charge enhancer packages that allow for the effective electret treatment of the resulting meltblown material prior to sterilization, where the filtration efficiency and pressure differential of the material are still adequate post-sterilization.

The present disclosure relates to the field of firefighter facial masks. More specifically, the present disclosure relates to a firefighter respirator mask device that includes a body, a facial covering over an opening of an SCBA mask, a fastening mechanism and a filter. The body of the device preferably resembles an ovular shape, or any shape that sufficiently covers the hole left over the mouth of an SCBA mask when not attached to an oxygenated hose, normally present under hazardous conditions. The device includes color-changing technology that allows the facial mask to turn colors in response to pathogenic exposure, indicating to the user that it is no longer sterile. In this manner, the device can be applied to any firefighter or industrial worker requiring the use of an SCBA without risk of possible pathogenic exposure when not attached to an oxygenated hose.

 Appl.No 19314055 Applicant Patient Knowhow, Inc. Inventor Devabhaktuni Srikrishna

A respiratory, skin, and eye protection device having at least one filter and at least one fan to maximize filtration while minimizing power consumption, noise generated, and device footprint. The least one filter is configured to simultaneously achieve an aerosolized particle contamination filtration efficiency of about 50% or greater for particles having a size of about 0.3 μm and a vapor contamination filtration efficiency of about 50% or greater for one or more of Novichok nerve agent (A232), thickened venomous nerve agent (TVX), sulfur mustard agent (HD), thickened sulfur mustard agent (THD), soman nerve agent (GD), and sarin nerve agent (GB). During the operation and monitoring of the respiratory, skin, and eye protection device, at least one fan is activated when concentrations of select aerosolized chemical, biological, radiological, nuclear, and explosive (CBRNE) agents are detected.

A protective headwear and respirator combination features a helmet having one or more predefined external mounting points thereon by which one or more accessories are externally mountable to said helmet, a respirator mask wearable together with said helmet in a face-worn position encompassing at least an oronasal portion of a face of the user to which inhalable air is admissible through an air intake port, and a a powered air purifying respirator (PAPR) comprising a blower unit configured for selective and removable mounting thereof to said helmet at one of said one or more predefined external mounting points thereon. A PAPR-mask interconnection conduit fluidically interconnects the blower outlet of the PAPR and the air intake of the respirator mask to convey ouptut air from the blower unit to the interior of the respirator mask, and comprises a thumbwheel coupler at an outlet end of the conduit.

An RPD fitting system configured to personalize respirator fit by generating actionable customization instructions. The system includes a respiratory device identifier that recognizes a specific respirator, and a user information retriever that obtains a user indication, such as a facial feature indication. A fit analyzer correlates the identified respirator with the retrieved user fit indication to determine a customization for the respirator and generates an instruction that, when implemented, changes a physical dimension of a respirator feature to improve fit (e.g., altering a face-seal-related dimension). A communication component delivers the customization instruction to the user for execution. By linking respirator identification with user-specific facial data and producing dimension-changing guidance, the system enables on-demand, user-tailored adjustments that enhance sealing performance and comfort across diverse respirator models and user anatomies.

The present invention relates to a mask manufacturing device and, more specifically, to a mask manufacturing device capable of manufacturing a mask that not only improves airtightness of a face portion but also eliminates inconvenience when the mask is worn, by forming wrinkles formed at a position covering the nose of a user in the mask in opposite directions to secure a space in a portion covering the nose of the user. To achieve the above-described end, the present invention comprises: a fabric supply unit installed at one end of an upper part of a base frame to supply a fabric; a wrinkle forming unit installed on the upper part of the base frame to form wrinkles on the fabric supplied from the fabric supply unit; and a fusion cutting unit installed at the other end of the upper part of the base frame to fuse and cut the wrinkled fabric discharged from the wrinkle forming unit.
