Disclosed is a method and device for inactivating or killing airborne bacteria, fungi, molds and viruses by passing the air through a filter material formed of a fabric having particles of zinc disposed in discrete physically isolated locations, wherein the particles of zinc and oxygen from the air form half cells of a battery whereby to create an electrical field that inactivates or kills airborne bacteria, fungi, molds and viruses passing through the filter material.

A cartridge for applying an electromagnetic field (EMF) to at least one toxin in a wound in the skin of a person or animal is provided. The cartridge includes a power supply, a controller coupled to the power supply and providing a voltage between about 0.2V and 3V to an array of electrodes configured to transmit the EMF to the skin about the wound site. A cartridge for applying an ultrasonic field to at least one toxin in a wound in the skin of a person or animal is also provided. The ultrasonic cartridge may include a power supply, a controller coupled to the power supply and providing a voltage to at least one sonotrodes configured to transmit the ultrasonic field to the skin about the wound. The cartridge may also include a sensor for measuring the resistance or impedance in the tissue to be treated and the controller can adjust the ultrasonic field based on the impedance or resistance.

The invention provides a system for sanitizing fluids such as water and air. In particular, the invention provides a combination of solid chlorhexidine and a polymer matrix, for which effluents are essentially free of leached chlorhexidine. The systems enable rapid disinfecting of fluids, including in line at the point of use, and can be employed for both high volume applications and disposable single-use applications.

Articles can be provided with odor resistance by applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier onto the surface of the article and allowing the inert liquid carrier to penetrate into it. The N-halamine accordingly becomes deposited on the surface of the article after the inert liquid carrier penetrates into the article. This method can be used to provide odor resistance to a variety of substrates, including garbage bags. It can also be used to deposit other functional particulates onto the surface of substrates having sufficient porosity to take up the vehicle. For instance, such functional particles can be oxidants that display antimicrobial and/or enzyme inhibitory efficacy or particles having toxin interaction potentials through oxidative degradation or adsorption of toxic substances in air and/or water, such as fluoride uptake by metal oxide microparticles.

A system and method for maintaining, monitoring and improving air quality and purity in a room or environment, such as a hospital room or operating room.

A miniature gas detection and purification device is disclosed for a user to carry with him, and includes a main body, a purification module, a gas guider and a gas detection module. The gas detection module detects the gas in the environment surrounding the user to obtain a gas detection datum, and controls the gas guider to be operated according to the gas detection datum, so that gas is inhaled into the main body and flows through the purification module for filtration and purification, and the gas purified is finally guided to an area nearby the user.

An air purifying apparatus for purifying air in an isolation space is disclosed. The isolation space is surrounded by a mask body and bounded from an outer space by the mask body. The air purifying apparatus includes a main casing, an intake device and a decontamination device. The main casing is formed with an accommodating space, an inner exhausting runner and an inner intake runner. The inner exhausting runner is communicated with the isolation space and the accommodating space. The inner intake runner is communicated with isolation space and the accommodating space. The intake device and the decontamination device are disposed in the accommodating space. The decontamination device is for purifying and decontaminating air in the accommodating space.

A disinfectant device including a pouch, the pouch including a first layer of material coupled to a second layer of material and defining a compartment therebetween. At least one dry reactant is retained within the compartment, the at least one dry reactant producing chlorine dioxide gas when exposed to water. A wick is at least partially disposed within the compartment. At least one from the group consisting of the first layer of material and the second layer of material define an array of ports along a periphery of the pouch and an array of fluid conduits, the array of fluid conduits being proximal to the array of ports, offset from the array of ports, in fluid communication with the wick, the compartment, and the array of ports.

The present invention is directed to filtered respiration that can occur according to multiple facets. The present invention includes a Continuous Positive Airway Pressure (“CPAP”) system, an adapter, and a CPAP interface. Other inventions disclosed herein relate to the modification of CPAP and BILEVEL-PAP systems into ventilators.
