摘要： A blood based solute monitoring system for measuring at least one blood solute species that has a first recirculation flow path in communication with a dialyzer. The first recirculation flow path is configured to allow a fluid to recirculate through a dialyzer such that the concentration of at least one solute species in the fluid becomes equilibrated to the solute species concentration of the blood compartment of the dialyzer. The blood solute monitoring system has at least one sensor to measure a fluid characteristic.

摘要： Systems, devices, and methods are provided for sensing gas bubbles within a liquid flow line, such as within a medical device. The systems, devices, and methods can measure a change in capacitance across a pair of conductive plates to calculate a volume of gas in a flow line. If a calculated volume of gas exceeds an established threshold, an alert can be sent and/or changes made to operation of the device.

摘要： Systems and methods for generating a brine solution using a canister for recharging zirconium phosphate in a reusable sorbent module are provided. The canister can include salt and have an inlet and an outlet. The inlet can extend upwardly into an interior of the canister above solid sodium chloride and sodium acetate. Water can be added to dissolve the salts in the canister and the resulting solution can be collected as a brine solution for use in recharging the zirconium phosphate.

摘要： Devices, systems, and methods for high capacity degassing of dissolved gases and gas bubbles from fluid such as a dialysate are provided. The devices, systems, and methods can include a degassing vessel with at least two degassing chambers. The fluid can be degassed in a first degassing chamber and recirculated through a second recirculating degassing chamber to remove a desired amount of gas such as carbon dioxide.

摘要： A single or multiple lumen catheter is disclosed which includes an expandable lumen. The expandable lumen is movable from a collapsed or sealed configuration to an open or expanded configuration. In the open configuration, the expandable lumen is dimensioned to receive a guidewire or stylet or facilitate the introduction of fluids into a patient.

摘要： A medical catheter includes an elongate member and an insert. The elongate member has proximal and distal end portions and defines a longitudinal axis through the proximal and distal end portions. The elongate member includes a wall at least partially defining a longitudinal lumen and defining a side opening extending radially from an outer surface of the wall to the longitudinal lumen. The insert is at least partially disposed within the side opening and at least partially defines an insert passage in fluid communication with the longitudinal lumen. The elongate member includes a first material defining the side opening and the insert includes a second material different from the first material.

摘要： In examples described herein, a system includes an elongate member configured to be introduced into vasculature of a patient. The elongate member includes a pressure sensor configured to generate a pressure signal indicative of pressure in the vasculature adjacent the needle. The system includes processing circuitry configured to receive the pressure signal from the pressure sensor, detect, based on the pressure signal, dislodgment of the elongate member from the vasculature, and generate an output in response to detecting the dislodgment of the elongate member from the vasculature.

摘要： Systems, devices, and methods are provided for measuring fluid flow across a pump used in a system for precisely and accurately metering fluid. The systems, devices, and methods can use contactless approaches to measure the properties of the fluid being pumped. The measured properties can be used to precisely and accurately determine the flow rate through the pump.
