An apparatus, system, and method for contacting blood with ozone to kill microorganisms in the blood are described. The method involves injecting microbubbles of ozone containing gas into a flow of blood, preferably at a temperature of less than 12° C. The apparatus includes a blood flow conduit including a blood ozone contacting portion including a porous ozone injector.

Dual-filter dual-integrity test assembly

A dual-filter dual-integrity test conduit assembly allows for in-situ testing of both filters with separate, duplicate systems for membrane integrity so that if the first tester filter fails, the second filter may be tested with a different, but identical method with its own gauges and nitrogen supply so as to further isolate malfunctions of the filter integrity test equipment as a cause for erroneous batch failures.

APPARATUS AND METHODS FOR INFECTIOUS VIRUS MITIGATION
20210379216 · 2021-12-09 ·

The present invention offers infectious virus mitigation apparatus that utilize one or more 3-dimensional porous metal substrate that impart virus mitigation effect. Fluid that contains or may contain infectious virus traverses through said substrate to achieve virus mitigation effect. Additional virus mitigation effect can be achieved by subjecting said virus mitigation apparatus to suitable wavelength(s) of light that enhance total virus mitigation effect and/or utilizing contoured cover glazing to induce fluid dynamics that can enhance total virus mitigation effect per pass of said fluid through said apparatus. The utility includes a wide variety of practical uses such as filtration of air, water, blood, and other fluids that contain or may contain infectious virus such as coronavirus.

METHOD FOR REMOVAL OF VIRUSES FROM BLOOD BY LECTIN AFFINITY HEMODIALYSIS
20210369933 · 2021-12-02 ·

The present invention relates to a method for using lectins that bind to pathogens having high mannose surface glycoproteins or fragments thereof which contain high mannose glycoproteins, to remove them from infected blood or plasma in an extracorporeal setting. Accordingly, the present invention provides a method for reducing viral load in an individual comprising the steps of obtaining blood or plasma from the individual, passing the blood or plasma through a porous hollow fiber membrane wherein lectin molecules are immobilized within the porous exterior portion of the membrane, collecting pass-through blood or plasma and reinfusing the pass-through blood or plasma into the individual.

In certain exemplary embodiments, an air purifier comprises a housing defining an enclosure and having an air entrance and an air exit; a particulate filter; a NCCO filter material configured to adsorb and decompose at least one gaseous pollutant; an AOG configured to generate at least one oxidant; an oxidant remover configured to remove at least one oxidant; a fan unit configured to generate airflow from the air entrance to the air exit; wherein the particulate filter, the NCCO filter material, the AOG, the oxidant remover and the fan unit are positioned within the enclosure such that during operation, a flow of air passes from the air entrance to the air exit through the particulate filter and the NCCO filter material along a direction of the flow of air. In certain embodiments, the air purifier may ensure safety to users while efficiency in removing contaminants can be greatly improved.

STERILIZATION DEVICE

A sterilization device includes a shell, an air guide passage, a sterilization module and a blowing device. An opening is formed in a side of the shell to face a handrail of an escalator. The air guide passage disposed in the shell includes an air inlet communicated with an ambient space outside the shell, and an air outlet facing and communicating with the opening. The sterilization module includes a plasma generator disposed in the air guide passage and capable of ionizing air and generating high-energy particles. The blowing device is configured to force air outside the shell into the air guide passage and blow the ionized air and the high-energy particles to the handrail. The sterilization device can accurately sterilize the handrail and realize sterilization based on air ionization, so the cost is low, and a pungent odor is avoided, which brings good experience to passengers riding the escalator.
