Abstract: A fluid treatment plant has a filter module including at least a first filter and a second filter connected in series and connectable to a supply of fluid. A pump is fluidly connected to the filter module and a controller with a fluid quality sensor is connected to detect a quality of the fluid between the first filter and the second filter. A filter module detector is connected to the controller configured to uniquely detect a filter module connected to the pump, and the controller is controls the pump responsively to a signal from the fluid quality sensor and the module detector. The controller is configured to continue pumping based on output of the quality sensor and/or based on output from the filter module detector.

Abstract: The present disclosure provides a system for processing ultramafic material. The system may comprise a reactor for accelerating weathering of said ultramafic material. The reactor may comprise one or more chambers comprising one or more microbes, biological medicators, or enzymatic accelerants to facilitate the weathering of the ultramafic material.

Abstract: A tool assembly for use with an electrosurgical device for cutting tissue includes a base portion, a return lead, an electrical insulator, a center pin, and an active lead. The center pin extends from the base portion and through a lumen of the electrical insulator. The active lead is securely fixed to the base portion and extends between the base portion and a distal portion of the center pin such that a portion of the active lead extends around the distal portion of the center pin and first and second segments of the active lead are spaced apart from the return lead. Upon activation, electrosurgical energy is transmitted from the active lead through tissue to the return lead to cut tissue in contact with the active lead.

Abstract: A fluid preparation system has a sealed sterilized fluid circuit with a sealed sterilized container with a conductivity sensor in communication with an interior of said container. Further, at least one sealed connector is adapted for adding fluid to said container, and at least one sealed connector is adapted for removing fluid from said container. The conductivity sensor is contained in a test line in communication with said interior and is adapted to be connected to a source of suction thereby to draw a sample of contents of said container. Furthermore, the test line may have a check valve to prevent ingress of contaminants into said container, and the sealed connector is adapted for adding fluid to said container and may have an inline sterile filter. Furthermore, the system may have a controller that controls pumping actuators.

Abstract: Systems, methods, and devices for preparation of water for various uses including blood treatment are described. In embodiments, fluid is passed either by pump or passively by gravity feed, through various filtration elements from a fluid source to a treatment fluid container. The latter forms a batch that may be used during treatment. Methods and systems for creating multiple-treatment batches are described. Advantages of creating a multitreatment batch include the fact that the burden of treatment preparation can be reduced and the timing of the preparation of the batch can be independent of the treatment time. As described, there are various trade-offs and concerns with this approach which are addressed by the inventive embodiments.

Abstract: A method and device for blood treatments that use fluids such as dialysate and replacement fluid for renal replacement therapy. In an embodiment, fluid is passed either by pump or passively by gravity feed, through a microporous sterilization filter from a fluid source to a replacement fluid container. The latter forms a batch that may be used during treatment. The advantage of forming the batch before treatment is that the rate of filtering needn't match the rate of consumption during treatment. As a result, the sterilization filter can have a small capacity. In another embodiment, a filter is placed immediately prior to the point at which the sterile fluid is consumed by the treatment process. The latter may be used in combination with the former embodiment as a last-chance guarantee of sterility and/or that the fluid is free of air bubbles. It may also be used as the primary means of sterile-filtration.

The latter forms a batch that may be used during treatment. The advantage of forming the batch before treatment is that the rate of filtering needn't match the rate of consumption during treatment which provides multiple benefits and liabilities to overcome, as discussed herein. Mechanisms for preparing pure water for infusion or medicaments are described such as elimination of chlorine and colloidal aluminum. Also various control mechanisms to help avoid contamination are describe.

Abstract: Systems, methods, and devices for preparation of water for various uses including blood treatment are described. In embodiments, fluid is passed through a first filtration step which is effective for creating purified water and a pair of ultrafilters placed at the outlet. The ultrafilters are separated by an intervening flow path to prevent grow-through from the outlet end upstream. In embodiments, a recirculation path with an air removing filter helps to eliminate air from the ultimate product water.

Abstract: A first connector of a connector assembly of a sterile batch container can be unsealed. The connector assembly can be attached to a filling port of the sterile batch container and can have a sterile filter arranged between the filling port and the first connector. The first connector can be coupled so as to receive produced purified water. A transmembrane pressure can be monitored across the sterile filter while flowing the purified water through the connector assembly into the sterile batch container so as to provide a sterile fluid stored therein. The connector assembly can be detached from the filling port of the sterile batch container. After the detaching, the sterile batch container can be coupled to the blood treatment system. In response to a change in the transmembrane pressure exceeding a predefined level, an alarm signal can be generated.
