Publication number: 20240075191Abstract: 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.Type: ApplicationFiled: November 14, 2023Publication date: March 7, 2024Applicant: NxStage Medical, Inc.Inventors: Jeffrey H.

Publication number: 20200061321Abstract: An exemplary suction catheter adaptor includes an adaptor body having a passageway between a proximal end and a distal end of the adaptor body. The proximal end of the adaptor body receives an instrument and, when coupled with an airway adaptor having a valve within a passageway between a proximal end and a distal end of the airway adaptor, the distal end of the adaptor body deflects the valve to permit the instrument to be advanced or retracted through the valve. A seal within the passageway of the adaptor body is biased to engage the valve during advancement of an instrument toward the valve, and the seal is disengaged when the instrument is retracted away from the valve. The valve, when not engaged, occludes the passageway between a proximal end and a distal end of the airway adaptor.Type: ApplicationFiled: November 1, 2019Publication date: February 27, 2020Inventors: Dennis WHITE, Haojun Fu
