Aspects of the present disclosure relate to a method of preventing transmission of an enveloped RNA virus. The method includes applying to a mucosal tissue of a first mammalian subject not substantially colonized by the enveloped RNA virus an effective amount of an antiseptic composition or a pharmaceutically acceptable salt thereof according to a treatment plan. The first mammalian subject not substantially colonized by the enveloped RNA virus interacts with a second mammalian subject colonized by the enveloped RNA virus at a first viral load, the first mammalian subject has a second viral load based on the interaction, the second viral load is no greater than 0.5 log increase over an initial viral load over a duration of the treatment plan. The mucosal tissue is in the nasopharynx, nasal cavity, or anterior nares of the mammalian subject. The antiseptic composition comprises iodine, iodophor, or combinations thereof.

Transmission prevention of viruses with application of antiseptic composition

The disclosed sterilization monitoring device comprises a perfusion channel with a chemical indicating composition disposed in fluid communication with the perfusion channel. Exposure to a sterilant creates a laterally moving front across the chemical indicating composition in the perfusion channel.

Process and device for generating a moving front within a sterilization monitoring device and uses thereof

A system for assessing efficacy of a sterilization process is disclosed. The system includes a biological indicator, a receptacle configured to receive the biological indicator, an actuator mechanism, and a sensing system operatively coupled to the actuator mechanism. A method of using the system for assessing efficacy of a sterilization process is also disclosed.

Activator system for biological indicator

The present disclosure relates generally to chemical indicators. In particular, the chemical indicators are useful for monitoring sterilization processes. The chemical indicator includes a fluid pathway and a chamber comprises a chemical-indicating composition.

Sterilization chemical indicator

A system includes a computing device a personal protective equipment (PPE) device. The PPE device is configured to be worn by a worker and includes and at least one physiological sensor configured to generate physiological data indicative of one or more physiological characteristics of a worker. The computing device is configured to determine a safety risk score for the worker based at least in part on the physiological data and a risk profile associated with the worker.

Personal protective equipment and safety management system having active worker sensing and assessment

Compositions include a compound preparable by reaction of components comprising an optionally crosslinked polyethylenimine and at least one an amine-reactive hydrolyzable organosilane represented by the formula R&#x2014;Z&#x2014;SiY. R represents an amine-reactive group containing 1 to 18 carbon atoms; Z represents a divalent organic group containing 1 to 8 carbon atoms; and each Y independently represents a hydrolyzable group. Methods of using the compositions to make articles, and articles produces thereby are also disclosed. A composition comprising an intimate mixture of a crosslinked polyethylenimine and a polymeric binder material, and a method of making it is also disclosed.

Compositions, method of making an article, and articles

Methods that include: subjecting an article including a moisture sensor to steam sterilization in a steam sterilizer to produce a sterilized article, the moisture sensor having a moisture absorbing layer and a resonant circuit; subjecting the sterilized article to drying; and interrogating the resonant circuit, wherein the interrogation is affected by an amount of water present in the moisture absorbing layer.

Methods of monitoring wetness utilizing a resonant circuit

A method of disinfecting a medical device comprises three steps. First, a disinfectant is contacted with a process indicator and the medical device. The disinfectant comprises at least one aldehyde. The process indicator contains a synthetic amine-containing compound disposed on a substrate. The synthetic amine-containing compound comprises at least one of primary amino groups or secondary amino groups, and is reactive with the disinfectant to form at least one adduct. The synthetic amine-containing compound and the medical device are in fluid communication through the disinfectant. A predetermined disinfectant exposure criterion exists for contacting the disinfectant with the medical device. Second, the process indicator is spectrally observed and at least one parameter is obtained therefrom that is predictive of the predetermined disinfectant exposure criterion. The third step is determining that the predetermined disinfectant exposure criterion has been achieved.

Method of disinfecting a medical device

Moisture sensors that include a resonant circuit having a capacitive element and an inductive element, wherein the inductive element acts as an antenna; a conditionally conductive polymeric layer, wherein the conditionally conductive polymeric layer has a first level of conductivity when exposed to a first set of moisture conditions and has a second level of conductivity when exposed to a second set of moisture conditions; and an insulative layer disposed between the resonant circuit and the conditionally conductive polymeric layer.

Electronic moisture sensor

Water-based formulations comprising an indicating composition dispersed in water are described. The water-based indicating compositions include an organic Bi(III) compound, a sulfur source, and a carbonate salt. Formulations further including a resin and/or an acidic additive are also described.

Water-based organic bismuth, elemental sulfur and lithium carbonate sterilization indicator composition

Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. When the thermoplastic polyester is selected to include aliphatic and aromatic polyesters, a spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. When the thermoplastic polyester is selected from aliphatic polyesters, a meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.

Light-activated antimicrobial devices and articles are disclosed. The devices include a light source and a light-activated antimicrobial article comprising a photosensitizer and a viscoelastic material such as a pressure sensitive adhesive adapted to receive light from the light source. The viscoelastic material may be adapted to transport light by total internal reflection. The photosensitizer may comprise a dye, a metal oxide or a composition that comprises anions that oxidize or react to form a gas. Upon activation of the light source, the photosensitizer absorbs light from the light source such that antimicrobial activity is exhibited. The photosensitizer may be included in the light-activated antimicrobial article or it may be provided as a topical composition that is separate from the article. The light-activated antimicrobial articles and devices may have constructions similar to those of wound dressings.

Light-activated antimicrobial article and method of use

Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. In some embodiments, the fibers comprise a viscosity modifier and/or an anionic surfactant. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.
