The present invention is a particulate filter face mask with replaceable filter element, the filter element being inexpensive, easily replaceable and securely held within the mask when installed.

The invention relates to a respirator mask comprising a filter material piece made of an air-permeable material and at least one securing band, wherein the air-permeable material comprises at least one layer of a non-woven fabric and the at least one securing band is designed to secure the respirator mask to the head, wherein the air-permeable material and the at least one securing band are made of the same plastic material.

The present invention relates to anti-microbial, antiviral, fibers, and fabrics and to devices made from said fabrics. The invention has particular utility in connection with personal protective equipment (PPE’s) such as surgical masks and respirators, and will be described in connection with such utilities, although other utilities are contemplated, including, for example for forming air handling filters for people movers, i.e., automobiles, trucks, buses, trains, ships and planes, as well as for forming filters for air handling equipment for buildings.

Methods, systems and apparatus for a pouch-style mask having upper and lower mask substrates, each having a first layer comprising spunbond material and a second layer comprising meltblown material, a perimeter comprising a user contacting portion and a non-user contacting portion, and a shoulder proximate a left-side transition between the user contacting portion and the non-user contacting portion and a shoulder proximate a right-side transition between the user contacting portion and the non-user contacting portion. The mask also has a head strap assembly comprising first and second head straps each having first and second end portions, where the first end portions of the first and second head straps are attached to the left upper and lower shoulders in a side-by-side configuration and the second end portions of the first and second head straps are attached to the right upper and lower shoulders in a side-by-side configuration.

A substrate with a pathogen inhibiting treatment. The substrate comprising a first coating of an inorganic material. The inorganic material being applied to the substrate via a vapour deposition process. A second coating applied at an upper surface of the first coating, and wherein the second coating is at least one of a protective coating for the first coating and a functional coating.

A personal respiratory protection device comprising a main body having a headband attachment portion, a headband attached to the headband attachment portion by a headband bond module, wherein the module includes first and second non-woven tabs adhesively bonded to opposing sides of an end of the headband, the side of the first tab opposing the headband bond side being welded to the main body.

A respirator for protecting against airborne particles includes a face gasket for providing a seal around the mouth and nose of a user, a frame attached to the gasket, a filter compression ring removably attached to the frame and a filter for filtering airborne particles from air. The filter is positioned between the frame and the filter compression ring. An eye protection accessory is attachable to the gasket. The respirator additionally includes a safety module that includes an air pressure sensor that can monitor the air pressure in the space bounded by the user's face and the filter. A processor analyzes the air pressure measurements obtained by the air pressure sensor and a vibration motor or a visual indicator. The processor can trigger the vibration motor and the visual indicator when the air pressure exceeds a predetermined threshold.

The scented filter system for a sanitary face mask is a medical device. The scented filter system for a sanitary face mask is adapted for use with a patient. The scented filter system for a sanitary face mask filters the air that flows through the nose and mouth of a patient. The scented filter system for a sanitary face mask a diffusing structure into a mask. The diffusing structure attaches to the mask. The mask filters the bulk of the air that flows through the nose and mouth of a patient. The diffusing structure: a) filters the balance of the air that flows through the nose and mouth of a patient; and, b) releases a volatile phytochemical into the air that flows through the nose and mouth of a patient.

A method of treating a spinal disk according to the present invention can include inserting an alloplastic bulking agent into the spinal disk to treat the defect. The alloplastic bulking agent has a plurality of microparticles and a suspending agent comprising hyaluronic acid. The bulking agent results in at least one of sealing the defect, increasing a pressure of the disk, increasing a height of the disk, improving stability of the disk and improving structural integrity of the disk.

A respiratory protection composite facepiece is disclosed and includes a polymeric rigid facepiece body portion having a first surface and a second surface and a silicone sealing facepiece element chemically bonded at least one of the first surface or the second surface. The first and second surfaces can be opposing major surfaces. A second silicone element is chemically bonded to at least one of the first surface or the second surface. Methods of making the same are also disclosed.
