The mist spray device according to the present invention is formed by including a mist generator configured to generate mists to above water surface of the water contained in a water tank, an air blower and an air guide part configured to form an air passage to allow the air flow generated by the air blower to be moved to a mist discharge port. Particularly, the water tank is disposed with an inlet through which part of the air flow generated by the air blower is introduced and an outlet through which the mists generated by the mist generator are discharged to the air passage, and an amount of air introduced into the water tank can be adjusted using the air inflow adjustment part.

A field of reach ultraviolet light disinfecting system includes a wrist band having two or more UV light emitters to produce a shower of UV light over the hand to disinfect pathogens that may be located on the hand and/or objects and surfaces in the light field of light dispersion the UV light emitters. A field of reach ultraviolet light disinfecting device has a top-hand UV light emitter configured on the wrist band to produce a top-hand UV light field that is emitted down over the top or back of a hand, when donned on a person's wrist. A field of reach ultraviolet light disinfecting device has a palm-hand UV light emitter that produces a palm-hand UV light field over the palm of a hand. A visible light emitter may project a visible light that overlaps the UV light field to indicate the location of the UV light emission.

A catheter insertion aid may comprise: an insertion tip located at a proximal end of the insertion aid; a flexible bag; a self-sealing mating mechanism on the proximal end of the insertion aid; and a physical interface that helps a user hold and support the insertion aid against the body when inserting the catheter tube into the male or female urethral tract. The catheter insertion aid may mate with a urinary intermittent catheter with a catheter tube to be inserted into a male or female urethral tract to facilitate drainage of urine from a bladder into a receptacle. The flexible bag may surround the catheter tube with a first collar connection mechanism connecting to the insertion aid and a second collar connection mechanism connecting to a catheter funnel. The self-sealing mating mechanism may mate with the catheter funnel to create a hermetic seal that is substantially air- and water-tight. The catheter insertion aid may further comprise a lubrication reservoir that holds a lubricant to coat a thin layer of the lubricant on the catheter tube facilitating insertion of the catheter tube into the male or female urethral tract.

Gamma ray and e-beam irradiation provided efficient sterilization of certain self-assembling peptides (including RADA16 in solution) without substantial degradation of the major peptide, while, e.g., another self-assembly peptide, QLEL12 was significantly degraded following irradiation. Irradiation sterilization enhances the rheological property of, for example, RADA16 hydrogel once applied to tissue at a physiological pH. The rheological property increase can result in higher efficacy in a variety of biomedical applications.

A device to provide sterilized surfaces and skin with the application of multiple bactericidal agents in combinations accentuating each agent's efficacy. UV, IR, and potentially others, in conjunction with minimal Ozone levels conditioned to rapidly move through the air surface/boundary layer for effective and timely activation of oxidizing effects on bacterial agents and secondarily through surface layer absorption for continued bacterial inactivation/oxidation after the stenlization event has occurred.

An entryway sanitizing assembly for neutralizing microbes on an entrant includes a frame, which defines an opening through which a user can pass. A first sensor, which detect motion, is engaged to the frame and can detect a user approaching the opening. A lamp engaged to the frame emits ultraviolet radiation into the opening to neutralize microbes on the user passes through the opening. A plurality of nozzles is engaged to the frame and is directed into the opening. A pump is operationally engaged to the plurality of nozzles and to a reservoir containing a disinfectant solution. The disinfectant solution is pumped by the pump to the nozzles to generate a disinfectant mist to neutralize the microbes on the user passing through the opening. A controller selectively actuates the lamp and the pump upon detection of motion by the first sensor.

A method for removing organic pollutants from water bodies by activating persulfate with nutrient-enhanced soybean sprout-based biochar involves a method for removing organic pollutants from water bodies by activating persulfate with biochar. The invention is intended to solve the technical problems that existing biochar materials show poor catalytic activity when used for activating persulfate and requires the addition of a large amount of modifiers, which easily leads to secondary pollution to the environment, and the existing biochar materials are susceptible to interference from halogen ions, oxoanions, and natural organic matters in a persulfate system. The raw material of a catalyst used in the invention is soybean, and has an activation process mainly based on non-radical activation, exhibiting high reaction rate and saving persulfate. With the addition of 0.2 g/L catalyst and 0.5 mM potassium persulfate, the degradation efficiency against 10 mg/L phenol can reach 100% within 10 min.

A method comprising a wearable device which consists of a smart band and a display unit. The smart band comprises a microbial biosensor, a particulate matter sensor, an enviro sensor, a single board computer, a power supply unit, a band fastener, and a set of watch adapters. The microbial biosensor detects, measures, and monitors beneficial microorganisms and pathogens in a nasal cavity, an oral cavity, or on a surface. The microbial biosensor sterilizer kills pathogens. The particulate matter sensor detects, measures, and monitors a set of suspended particles in the surrounding air comprising beneficial microorganisms, pathogens, pollen grains, dust mite allergens, and an air quality index. The particulate matter sensor sterilizer kills pathogens. The enviro sensor detects, monitors, and measures environmental conditions surrounding the user.
