  • Patent number: 7976711
    Abstract: A method and device for blood treatments that use fluids such as dialysate and replacement fluid for renal replacement therapy. In an embodiment, fluid is passed either by pump or passively by gravity feed, through a microporous sterilization filter from a fluid source to a replacement fluid container. The latter forms a batch that may be used during treatment. The advantage of forming the batch before treatment is that the rate of filtering needn't match the rate of consumption during treatment. As a result, the sterilization filter can have a small capacity. In another embodiment, a filter is placed immediately prior to the point at which the sterile fluid is consumed by the treatment process. The latter may be used in combination with the former embodiment as a last-chance guarantee of sterility and/or that the fluid is free of air bubbles. It may also be used as the primary means of sterile-filtration.

  • Patent number: 7780619
    Abstract: A blood processing machine has a compact configuration in which the first and second parts of the machine separate to open a gap between them. The actuators and sensors face into the gap such that when a cartridge with a fluid circuit is placed in the gap and the two parts are brought together closing the gap, the actuators and sensor engage the fluid circuit. One of the parts has an operator interface with a display that is preferably aligned with the gap in such a way that the frontal area of the machine is minimized.

  • Patent number: 7473238
    Abstract: A disposable fluid circuit kit for extracorporeal blood treatment systems that supply replacement fluid to a patient is described. The circuit has a blood portion that carries blood and subjects it to some treatment, such as dialysis or hemofiltration. A portion carries filtrate or dialysate. A replacement fluid portion that carries fluid used to compensate for fluid loss is connectable to a supply of replacement fluid. a sterilizing filter in the replacement fluid portion sterilizes the replacement fluid before introduction into the patient acting as a guard against touch contamination of the connected replacement fluid container. Preferably, the filter has a pore size effective to eliminate pyrogens.

  • Publication number: 20080230450
    Abstract: Systems, methods, and devices for preparation of water for various uses including blood treatment are described. In embodiments, fluid is passed either by pump or passively by gravity feed, through various filtration elements from a fluid source to a treatment fluid container The latter forms a batch that may be used during treatment. Methods and systems for creating multiple-treatment batches are described. Advantages of creating a multitreatment batch include the fact that the burden of treatment preparation can be reduced and the timing of the preparation of the batch can be independent of the treatment time. As described, there are various trade-offs and concerns with this approach which are addressed by the inventive embodiments.

  • Publication number: 20080228125
    Abstract: In general, this invention relates to methods and devices for introducing and/or draining fluids into and/or from a patient's body. Methods and devices are provided for rendering conventional tubing sets, or fluid flow sets, which are normally coupleable with only specific complementary patient access devices, compatible with other access devices also. In accordance with one aspect of the invention, methods and devices are provided which render conventional extracorporeal tubing sets to be interchangeably connectable with other specific transcutaneous catheters. In yet another aspect of the invention, non-conventional tubing sets and corresponding non-conventional access devices for use in hemodialysis, or hemofiltration, are provided such that specific tubing sets and access devices can be used interchangeably.

  • Patent number: 7419597
    Abstract: A method for renal replacement therapy includes priming a fluid circuit and recirculating the sterile fluid during priming to permit gas to float out of the sterile fluid into a fluid reservoir. The fluid is preferably either warmed during circulation or vibrated to promote the removal of gas.
