  • Patent number: 11957465
    Abstract: Apparatuses, methods, and systems are disclosed for accelerated ergonomic collection of capillary blood. An apparatus and system include a blood collection module with a proximal portion including a vacuum generation chamber, a distal portion including a blood collection chamber, a concave mid portion including a pressure equalization channel configured to equalize reduced air pressure. The apparatus further includes a sealing surface to stably seal the blood collection module to the skin around a collection site and a slide latch actuated by a lengthwise sliding motion. Also included is a lancet carrier with linearly-arranged lancet strips to puncture rows of blood extraction slits in the collection site. The apparatus also includes an angled transfer port with a low-resistance non-microfluidic blood flow channel to a transfer module, then to a plasma separation module with a multilayer laminate and plasma separation membrane. Methods for accelerated ergonomic collection of capillary blood are disclosed.

  • Publication number: 20180257028
    Abstract: A method and system for collecting gaseous nitrogen compounds into an aqueous solution are provided. The method enables the combination of gaseous sulfur and nitrogen compounds in the aqueous solution to generate ammonium compound components, to include ammonium sulfate. Sulfur may be pressure injected into the solution as gaseous sulfur dioxide. Optionally, carbon may be introduced into the solution as gaseous carbon dioxide. The sulfur may be earlier sourced by a burning of a sulfurous solid. The pH of the solution may be monitored and the introduction of ammonia, carbon and/or sulfur may be halted or constrained while the pH of the solution is measured outside of specified range. The solution may be allowed to age to permit a mix of compounds of ammonium carbonate, ammonium bicarbonate and ammonium carbonate to restabilize and thereby encourage a renewed surge of ammonium sulfate generation.

  • Publication number: 20140017161
    Abstract: An aerobic composting process for producing an organic ammonium sulfate product is provided, including providing an enclosed composting apparatus for decomposition of a source of nitrogen; mixing said source of nitrogen with a source of carbon, thereby creating a biomass having a high solids content; moving said biomass down the composting trench as the aerobic composting process progresses; providing aerobic bacteria to highly selectively convert the available nitrogen compounds from said biomass into NH3 and/or NH4 and CO2 without addition of external heat; capturing the NH3 and/or NH4 and CO2 from the atmosphere of the composting apparatus in an aqueous solution; adding a source of sulfate to said aqueous solution containing captured NH3 and/or NH4 and CO2; and processing said aqueous solution containing a source of sulfate and captured NH3 and/or NH4 and CO2 to obtain preferrably organic ammonium polycarbonate and/or solid or concentrated liquid ammonium sulfate product.
