  • METHOD AND APPARATUS FOR MACHINE ERROR DETECTION BY COMBINING MULTIPLE SENSOR INPUTS
    Publication number: 20130281799
    Abstract: One of the most significant safety concerns in the automation of extracorporeal blood treatments such as dialysis is the risk of blood leakage. Extracorporeal blood treatment systems draw blood at such a high rate that a loss of integrity in the blood circuit can be serious. There are a number of mechanisms for detecting and preventing leaks, but none is perfect. This tends to limit the use of such equipment in unsupervised settings, such as the home will be limited. Some leak detection schemes can be made sensitive enough to detect the barest of leaks, but when this is done, they result in too many false positives. The invention combines information from multiple inputs to enhance sensitivity in leak detection and reduce the problem of false positives.

  • BATCH FILTRATION SYSTEM FOR PREPARATION OF STERILE FLUID FOR RENAL REPLACEMENT THERAPY
    Publication number: 20130264250
    Abstract: A first connector of a connector assembly of a sterile batch container can be unsealed. The connector assembly can be attached to a filling port of the sterile batch container and can have a sterile filter arranged between the filling port and the first connector. The first connector can be coupled so as to receive produced purified water. A transmembrane pressure can be monitored across the sterile filter while flowing the purified water through the connector assembly into the sterile batch container so as to provide a sterile fluid stored therein. The connector assembly can be detached from the filling port of the sterile batch container. After the detaching, the sterile batch container can be coupled to the blood treatment system. In response to a change in the transmembrane pressure exceeding a predefined level, an alarm signal can be generated.

  • Filtration system for preparation of fluids for medical applications
    Patent number: 8545428
    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. The advantage of forming the batch before treatment is that the rate of filtering needn't match the rate of consumption during treatment which provides multiple benefits and liabilities to overcome, as discussed herein. Mechanisms for preparing pure water for infusion or medicaments are described such as elimination of chlorine and colloidal aluminum. Also various control mechanisms to help avoid contamination are describe.

  • Batch filtration system for preparation of sterile fluid for renal replacement therapy
    Patent number: 8202420
    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.

  • Fluid line connector safety device
    Patent number: 8042838
    Abstract: Devices can use various features to prevent the disconnection of connectors used in medical treatments. For example, a disconnection prevention member can have ends which hold luer connectors such that a male luer connector is prevented from separating from a female luer connector. The member can thus prevent disconnection of luer connectors that are incompletely mated.
