Patent number: 9138380Abstract: A package has a transport/storage state for storing powdery material which is to be mixed with a solvent to form a medical solution. The package includes a compartment which is at least partially defined by two opposing wall portions, and a connector. In the transport/storage state, the compartment contains the powdery material in the form of at least two distinct sets of powdery material of different compositions, where the opposing wall portions are brought into engagement with the powdery material so as to immobilize the sets of powdery material. When used for preparation of the medical solution, a fluid is selectively admitted into the package via the connector so as to expand the compartment and enable mixing of the sets of powdery material with the solvent in the compartment.Type: GrantFiled: June 20, 2011Date of Patent: September 22, 2015Assignee: Gambro Lundia ABInventors: Olof Jansson, Lennart Jonsson, Torbjorn Linden, Jan Sternby, Ragnar Tryggvason, Anders Wieslander

Patent number: 8617482Abstract: A capping device is configured to terminate a connector while disconnected from another connector in a fluid transportation system, e.g., for peritoneal dialysis. The connector comprises an exposed surface portion that is enclosed when the connector is connected to the other connector. The capping device comprises a body defining a chamber with an opening, a liquid-containing disinfectant in the chamber, a sealing element arranged in the opening to form a sealed cavity retaining the disinfectant, and a structure for engaging and guiding the connector towards the body such that a portion of the connector displaces the sealing element into the chamber. The sealed cavity is configured such that a displacement of the sealing element into the chamber actively presses the disinfectant out of the sealed cavity, for disinfecting at least part of the exposed surface portion.Type: GrantFiled: June 15, 2009Date of Patent: December 31, 2013Assignee: Gambro Lundia ABInventors: Ragnar Tryggvason, Mikael Axelsson

Publication number: 20130315801Abstract: A cartridge configured to be connected to a blood treatment apparatus, the cartridge including a cartridge inlet, a cartridge outlet and chambers each of which is configured to hold a concentrate in powder form. A flow controller is configured to provide a flow passage from the cartridge inlet to a single selected chamber of the chambers and from the single selected chamber to the cartridge outlet. The flow controller is movable between a plurality of positions, such that a position of the flow controller defines which of the plurality of chambers is the single selected chamber.Type: ApplicationFiled: November 11, 2011Publication date: November 28, 2013Applicant: Gambro Lundia ABInventors: Lennart Jonsson, Ragnar Tryggvason

Patent number: 8469931Abstract: A medical product configured for use in a medical system and a method of handling a medical system comprising a first subsystem and a second subsystem containing a medical fluid are provided. A connector connects the first and second subsystems for transport of the medical fluid from one of the subsystems to the other subsystem. The connector comprises a valve device, a first connection pipe connectable to the first subsystem, and a second connection pipe connectable to the second subsystem. The valve device comprises a first part and a second part, which are movable in relation to each other to permit an opening movement from a closed position, preventing a fluid communication between the first and second connection pipes, and an open position permitting the fluid communication. The medical product comprises a blocking member preventing, in a blocking state, the opening movement, and permitting changing of the blocking state to a non-blocking state permitting the opening movement.Type: GrantFiled: March 4, 2008Date of Patent: June 25, 2013Assignee: Gambro Lundia ABInventors: Ragnar Tryggvason, Peder Flank

Patent number: 8357143Abstract: A medical product is configured for use in a medical system. A method is provided for sterilizing the product. A connector connects a first subsystem and a second subsystem, containing a medical fluid, for transport of the medical fluid from the second subsystem to the first subsystem. The connector comprises a valve device, a first connection pipe connected to the first subsystem, and a second connection pipe connected to the second subsystem. The valve device comprises a first part and a second part movable relative to each other to permit an opening movement from a closed stable position, which prevents a fluid communication between the connection pipes, to an open position, which establishes a channel permitting the fluid communication. The connector comprises at least one small passage permitting, in the closed stable position, an introduction of a sterilizing gas to contact wall surfaces defining the channel.Type: GrantFiled: March 7, 2008Date of Patent: January 22, 2013Assignee: Gambro Lundia ABInventor: Ragnar Tryggvason

Publication number: 20060204405Abstract: The present invention relates to a device for use in a cartridge (9), a cartridge, a use of a device in a cartridge and a system for preparing a liquid solution for a medical procedure. The device comprises a hollow body (24) defined by a wall (50) enclosing a cavity space of the body. The body (24) has a first end (52) and a second end (53), and is provided with a least one slit-shaped opening (55) extending through the wall. The first end is open and adapted for receiving liquid to be introduced into the cartridge. The liquid leaves the device through the slit-shaped opening in a flow direction. The slit-shaped opening has a first extension and a second extension substantially perpendicular to the flow direction and to the first extension. The second extension is significantly shorter than the first extension.Type: ApplicationFiled: April 7, 2004Publication date: September 14, 2006Inventors: Ragnar Tryggvason, Jan-Olof Lorentzon, Ingvar Losell
