  • Pressure measurement devices, methods, and systems
    Patent number: 9551625
    Abstract: A pressure measurement system for use in blood circuits comprised of a pressure sensing pod and a force measurement device. The pressure sensing pod can include a flexible, moveable, fluid-impermeable diaphragm and can be formed via either a one-shot or a two-shot molding process. A mechanical engagement member of the force measurement device engages with a mechanical engagement feature of the diaphragm, and the engagement member is operative to move in concert with movement of the engagement feature of the diaphragm based on pressure variations with the pressure sensing pod. The force measurement device generates and outputs to a processor a signal based on detected force associated with movement of the engagement member.

  • Filtration System For Preparation Of Fluids For Medical Applications
    Publication number: 20160303305
    Abstract: Systems, methods, and devices for preparation of water for various uses including blood treatment are described. In embodiments, fluid is passed through a first filtration step which is effective for creating purified water and a pair of ultrafilters placed at the outlet. The ultrafilters are separated by an intervening flow path to prevent grow-through from the outlet end upstream. In embodiments, a recirculation path with an air removing filter helps to eliminate air from the ultimate product water.

  • METHOD AND APPARATUS FOR MACHINE ERROR DETECTION BY COMBINING MULTIPLE SENSOR INPUTS
    Publication number: 20160206803
    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.

  • WATER TREATMENT SYSTEMS, DEVICES, AND METHODS FOR FLUID PREPARATION
    Publication number: 20150374895
    Abstract: A water purification component, which may be integrated in a medicament production plant and/or a blood treatment system, removes chloramine and other chlorine compounds and deionizes water. The deionization is selected to be effective for providing product water whose resistivity is sufficiently high to allow chloramine to be detected in the product water if the chloramine removal filtration fails. This allows a chloramine removal filter to be changed based on a predicted exhaustion schedule with the safety of automatic chloramine breakthrough provided.

  • BATCH FILTRATION SYSTEM FOR PREPARATION OF STERILE FLUID FOR RENAL REPLACEMENT THERAPY
    Publication number: 20140238909
    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.

  • Filtration system for preparation of fluids for medical applications
    Patent number: 8679348
    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.
