  • Patent number: 12226557
    Abstract: The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.

  • Patent number: 12171926
    Abstract: A method for measuring pressure includes securing a flow channel to a chassis of a measurement device, the flow channel having a flexible wall with a first mechanical engagement feature presented from an external surface thereof. The method also includes engaging the mechanical engagement feature with a complementary engagement member connected to a force transducer, the securing being effective to immobilize the flow channel relative to the force transducer, and detecting at least one of the position and orientation of the of the flow channel relative to transducer and comparing to at least one of a predefined position and orientation. Further, the method includes generating a signal responsive to the detecting, flowing a fluid through the flow channel, and transmitting forces caused by displacement of the flexible wall through the complementary engagement member to the force transducer. Further, electrical signals are generated responsively to a state of the force transducer.

  • Patent number: 12156958
    Abstract: A medicament preparation system includes a disposable cartridge with a flow path. Various sensors may be placed on the cartridge to measure qualities of the fluid flowing through the flow path. The sensors are placed in precise locations using various approaches that make manufacturing of the cartridge efficient and repeatable. A drain line that is susceptible to fouling may be preattached and various approaches are used to remove or reduce the fouling. An elastomeric contact can also be present in the medical preparation system and used in a conductivity measurement subsystem.

  • Patent number: 11747043
    Abstract: A low leakage current fluid heater and systems and methods thereof. The fluid heater has a configuration whereby a heating element is isolated from a fluid channel so as to leak into fluid passing through the channel an allowed amount of leakage current. Fluid passing through the fluid heater can be heated to a desired temperature. A controller can provide control signals to driver the fluid heater to the desired temperature and maintain the temperature at the desired temperature.

  • Patent number: 11529448
    Abstract: A pressure measurement pod for use in blood circuits includes a pressure sensing pod defining a chamber and having a rigid wall portion and an integral flexible wall portion forming a flexible, moveable, fluid-impermeable diaphragm with a first major side thereof facing an interior of the chamber and a second major side opposite the first major side. The second major side faces outwardly away from the chamber, and the pod has ports on sides of the chamber. The internal surfaces of the chamber and ports are shaped such that any contour following the internal surfaces to the outside of one of the ports traces only surfaces characterized by positive or neutral draft angles such that invasive mold portions may be withdrawn through the ports thereby permitting the pressure measurement pod to be molded in a single shot molding process.
