  • Patent number: 8277407
    Abstract: Artificial kidney for gradual, and at least semi-continuous, blood treatment, wherein a blood stream is fed from a body of a living human or animal being into the artificial kidney, where anticoagulation is first effected, blood cells and molecules of large and medium molecular weight, such as proteins, are then primarily separated from plasma and fed back to the blood stream, regulating a water and salt balance by diverting excess plasma water and further removing from the blood stream, plasma or plasma water accumulated and toxic substances, by removal of specific electrolytes and waste products and wherein purified or partially purified plasma and plasma water is being carried back to the blood tract of the body.

  • Patent number: 8246564
    Abstract: This invention discloses a modular system having a base module, a mid-section control module, and a display module for preparing and administering a gas-enriched bodily fluid. Gas-enrichment is achieved by a gas-enriching device which can be in the form of a disposable cartridge. During operation, the gas-enrichment device is placed in an enclosure within the control module to form a fluid pathway for extracorporeal circulation of the bodily fluid. An electronic controller manages the various aspects of the system and executes an automated method for priming the extracorporeal circuit.

  • Patent number: 8206368
    Abstract: Disclosed is a dispensing system a dispenser having a first chamber containing a first material and a second chamber containing a second material. The dispenser is configured to selectively retract one of the chambers at least partially within the other to transition the dispenser between an extended position and a compact position. The first chamber includes an open top end that is, before use, covered with a first breakable membrane. A breaker ring, at least initially covered with a second breakable membrane, is configured to break the breakable membranes when the dispenser is transitioned between an extended position and a compact position. In the compact position, with the membranes broken, the first material and second material are free to form a mixture that can be dispensed via an opening in the dispenser's openable tip.

  • Patent number: 8192412
    Abstract: According to one aspect of the disclosure, a portable fluid storage device comprises a fluid impervious container having an interior space for the collection of human waste and a hollow tailpiece removably extending from the fluid impervious container and providing sealed fluid communication between an inlet end of the hollow tailpiece and the interior space. A cap is removably disposed at the inlet end of the hollow tailpiece and has a lumen disposed therethrough to provide a point of entry for the human waste into the portable fluid storage device. A flexible conduit is movably disposed within and removable from the hollow tailpiece and has an inlet end removably connected to an outlet end of the cap and an outlet end in fluid communication with the interior space of the fluid impervious container.

  • Patent number: 8177736
    Abstract: The invention relates to a device and to a method for monitoring access to vessels during extracorporeal blood treatment. The invention forms a loop in the arterial and/or venous line and provides device for fixing a section of the line in a loop. When the line is stressed under tension, the loop contracts and the line finally kinks. The modification of the diameter of the line and the formation of a kink in the line leads to a rise of pressure in the line, which is monitored by a pressure monitoring device. If the pressure exceeds a predetermined threshold value, the aspirating cannula is in danger of slipping out of the vessel access or has partially or completely slipped out, thus allowing the threshold value to be determined for alarms.

  • Patent number: 8152792
    Abstract: A subcutaneous drain, preferably for implantation into the skull of a patient comprises a basically hollow cap and a stem with an inside, central passageway passing from top of the cap through the stem. A lumen is provided through at least a portion of the inside, central passageway with the lumen preferably exiting the cap through a side slit in the cap and stem. The lumen is provided with a supporting ledge to reduce kinkage and promote an unimpeded fluid path. The side slit is resilient to allow for the selective removal of the lumen. The cap and stem are, as mentioned, substantially hollow and defines a chamber in communication with the subdural space, so that with the device in place, a physician can use a hypodermic needle to gain access to fluid in the subdural space by piercing the needle tip of the hypodermic syringe or needle through the thin wall of the cap of the device. A circumferential flange is provided to facilitate location of the device. Also, the stem is slightly inwardly tapered.

  • Patent number: 8109917
    Abstract: Disclosed is a dispenser having a first chamber containing a first fluid and a second chamber containing a second material. Each chamber has screw threads that are selectively joinable so that the first and second chambers are twistable relative to one another. The first chamber includes an open top end that is, before use, covered with a breakable membrane. A breaker ring is located within the second chamber and is configured to break the breakable membrane when the dispenser is transitioned between an extended position and a compact position. In the compact position with the breakable membrane broken, the first fluid and second material form a mixture that can be dispensed via an opening in an openable tip.
