Patent number: 11779519Abstract: The invention provides, in some aspects, a container system for medical solutions such as peritoneal dialysis (PD) solutions. The invention particularly features a system which includes a first compartment that contains a first medical solution, e.g., a PD osmotic agent, and a second compartment that contains a second medical solution, e.g., a PD buffer agent. The compartments maintain their respective contents separately from one another for purposes of transport, storage and/or sterilization. However, the compartments are fluidly couplable, so that their respective contents can be combined with one another, e.g., following sterilization of the agents and prior to their introduction into the patient's abdomen. To that end, a container system can include a diffuser that is disposed in a fluid pathway between the first and second compartments, e.g., to facilitate homogeneous mixing of the first and second PD agents.Type: GrantFiled: October 9, 2020Date of Patent: October 10, 2023Assignee: FRESENIUS MEDICAL CARE HOLDINGS, INC.Inventors: Lynn E. Jensen, Venugopal R. Ghatikar, DeLoy Lindley, Melvin D. Jensen

Publication number: 20220387259Abstract: A container system includes at least one flexible wall defining a compartment containing a dissolvable solid or concentrate, a support adjacent a first end of the at least one flexible wall, and a nozzle assembly coupled to a second end of the at least one flexible wall. The second end of the wall is distal from the first end. The nozzle assembly comprises a hollow body defining a longitudinal axis. The hollow body further defines a plurality of orifices through a wall thereof. Each orifice is able to form a fluid connection between an interior volume within the hollow body and the compartment. Each orifice is configured to deliver liquid from the interior volume to the compartment in a direction having an angle of between 5° and 85° from a direction of the longitudinal axis. Related nozzles and methods are also disclosed.Type: ApplicationFiled: August 9, 2022Publication date: December 8, 2022Inventors: Lynn E. Jensen, DeLoy Lindley, Natalie Rebacz, Mary Hoover, Troy Dayton, Michael P. Smith

Patent number: 10518013Abstract: The present invention relates to a dialyzer holder to attach a dialyzer to a dialysis machine. During priming of a bloodline prior to a dialysis treatment, the dialyzer holder grips a dialyzer in approximately the center of the dialyzer, but allows movements of the dialyzer in an arc motion using two axes of rotation. The holder enables the dialyzer to move to a position where air can be primed from the dialyzer and, because the dialyzer can move toward the dialysis machine, this motion eliminates stress on the tubing connected to the bottom and top of the dialyzer and reduces the length of bloodline tubing necessary to accommodate dialyzer movement. The dialyzer holder incorporates an attachment point for a venous chamber for use during the priming procedure, enabling the venous chamber to move with the dialyzer, further reducing the tubing between the dialyzer and the venous chamber.Type: GrantFiled: May 14, 2019Date of Patent: December 31, 2019Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Lynn E. Jensen, DeLoy Lindley, Troy Dayton

Patent number: 10398826Abstract: A pressure output device (POD) assembly for sensing fluid pressure in a fluid processing system, is provided. This POD assembly includes a shell defining a shell interior, and a movable diaphragm disposed in the shell interior and separating the shell interior into a flow-through chamber and a pressure sensing side. A sensor port is in fluid communication with the pressure sensing side. An inlet port and an outlet port are in fluid communication with the flow-through chamber. The inlet port and the outlet port define an inlet and an outlet, respectively, of a flow-through channel that passes through the flow-through chamber. A boss protrudes from the interior wall of the shell and extends into the flow-through channel to prevent occlusion of flow under different pressure conditions within the flow-through chamber.Type: GrantFiled: July 13, 2017Date of Patent: September 3, 2019Assignee: Fresenius Medical Care Holdings, Inc.Inventors: DeLoy Lindley, Jose Antonio Badillo, Michael Parry Smith, Richard Allen Lasher, Troy Calvin Dayton, Lynn E.
