  • Publication number: 20160103077
    Abstract: A liquid contaminant sensor system and method. An example system includes at least one light source. The example system includes at least one light detector to receive a light signal from the at least one light source. The example system includes a signal processor to compare the light signal received at the at least one light detector with a reference signal and determine if a particle is present in a liquid. An example liquid contaminant sensor method includes emitting a light into a detection path and a reference path, detecting a light signal from the detection path and the reference path, and comparing the light signal with a reference signal to determine if a particle is present in a fluid. In an example, a fluid path is split into a detection path and a reference path. In another example, the fluid path includes both the detection path and reference path.

  • Publication number: 20160101225
    Abstract: A dialysis system is disclosed. An example dialysis system includes a heat disinfected dialysate fluid path. The example dialysis system also includes a disposable blood fluid path. The example dialysis system also includes an active carbon filter to purify influent water to purified water for dialysis or as a substitution fluid. An example method for dialysis includes providing a heat disinfected dialysate fluid path, providing a disposable blood fluid path, and purifying influent water via an active carbon filter to for dialysis or as a substitution fluid.

  • Publication number: 20150298999
    Abstract: A water purification system is disclosed. An example of the water purification system includes a transportable water machine to generate purified water. The example transportable water machine includes fluid treatment subsystems including at least a pre-treatment subsystem, a Capacitive Deionization (CDI) subsystem, a mix and filter subsystem, and an output subsystem. The example transportable water machine also includes a mechanical subsystem to support the pre-treatment subsystem, CDI subsystem, mix and filter subsystem, and the output subsystem. The example transportable water machine also includes an electrical subsystem to support the pre-treatment subsystem, CDI subsystem, mix and filter subsystem, and the output subsystem. in an example, influent (e.g., tap water) to the water purification system is passed through one or more filter (e.g., a series of filters) to remove large particles, ions, organic molecules, inorganic molecules, and biological material.

  • Publication number: 20150299002
    Abstract: Activated carbon filter (ACF) system and method are disclosed. An example of the ACF system includes a plurality of activated carbon electrodes, The ACF system includes at least one current spreader for each of the plurality of activated carbon electrodes. The ACF system includes an electrical connection to provide electrical power to the plurality of activated carbon electrodes via the at least one current spreader. The ACF system includes an inlet and an outlet configured to provide fluid through a flow path in the plurality of activated carbon electrodes to remove contaminant from the fluid. The ACE system actively deionizes and removes chemical, biological, and/or other particles from a fluid (e.g., tap water).

  • Publication number: 20150299000
    Abstract: A fluid handling system is disclosed as it may be implemented to purify water. In an example, a single-unit fluid handling system includes a stationary filter, a mobile tank, and an end effector subsystem. The stationary filter has a Capacitive Deionization (CDI) subsystem. The stationary filter also has a mix and filter subsystem, and an output subsystem. The mobile tank has a tank subsystem, and a tank liner subsystem. The system may also include a waste handling component having a waste tank subsystem. In an example, purified fluid is maintained in physical, chemical, and biological isolation from waste fluid on the same device. Although not limited in end-use, the fluid handling system may be configured to further combine the purified water with medical fluid concentrate, store the fluid, and then dispense the product, e.g., via a medical device for use in a medical treatment procedure and/or surgery.

  • Patent number: 5335486
    Abstract: An apparatus and method for forming fluid-containing envelopes from two superimposed layers of enclosure material, defining a workpiece, by transporting the workpiece on a support to a plurality of processing stations. One of the processing stations forms at least a portion of the perimeter of each envelope to be formed from the workpiece by appropriately sealing the two layers together in a predefined pattern. At least one inlet coinciding with an unsealed portion of the layers is provided for each such envelope such that an appropriate fluid may be provided thereto when the workpiece is positioned at another processing station. Advantageously, the workpiece is maintained in a certain position on/relative to the support when provided to the envelope filling/forming station and other processing stations which may be incorporated (e.g., secondary sealing station, die cutting station).
