Automatic Control Patents (Class 210/143)
  • Patent number: 10252920
    Abstract: Data relating to fluid dynamics is obtained using a flow field sensor that measures acceleration and angular velocity of the sensor on three axes. Ballast control allows the sensor to obtain neutral buoyancy within the fluid. The sensor is effective in opaque fluids and closed containers as data is stored in a removable memory. Froth flotation systems are among the applications for the sensor. The small size, the geometry, and the center of mass of the sensor allow it to follow the flow field in a vessel without material disruption of the flow field or weight-induced angular displacement.

    Abstract: A peritoneal dialysis system includes a base peritoneal dialysis system and a peritoneal dialysis fluid exchange system that operates independently of the base system. The base system includes a first cassette including a first patient line configured to be connected to a patient, and a PD cycler. The PD cycler receives the first cassette, and includes a pump that cooperates with the first cassette to deliver dialysate to and drain dialysate from a peritoneal cavity of the patient via the first patient line. The peritoneal dialysis fluid exchange system includes a second cassette including a second patient line configured to be connected to the patient and a fluid exchange device that receives the second cassette. The fluid exchange device includes a data exchange interface operable to transfer patient treatment data from the peritoneal dialysis fluid exchange system to the base peritoneal dialysis system.

  • Patent number: 9427513
    Abstract: A device monitors a blood path from a blood vessel access of a human subject through an extracorporeal blood processing apparatus and back to the blood vessel access. A pumping device in the blood path is operable to pump blood through the blood path from the blood withdrawal device to the blood return device. The monitoring device obtains pressure data from a pressure sensor arranged upstream of the pumping device in the blood path, and processes the pressure data for detection of a disruption of the blood path downstream of the pumping device, e.g. caused by VND (Venous Needle Dislodgement).

  • Patent number: 9408961
    Abstract: A membrane separation device is disclosed along with systems and methods employing the device in blood processing procedures. In one embodiment, a spinning membrane separator is provided in which at least two zones or regions are created in the gap between the membrane and the shell, such that mixing of the fluid between the two regions is inhibited by a radial rib associated with the membrane that decreases the gap between the membrane and the shell to define two fluid regions, the ridge isolating the fluid in the two regions to minimize mixing between the two. Automated systems and methods are disclosed for separating a unit of previously collected whole blood into components, such as concentrated red cells and plasma, for collecting red cells and plasma directly from a donor in a single pass, and for cell washing. Data management systems and methods and priming methods are also disclosed.

    Abstract: A hemodialysis apparatus 1 is provided with a dialyzer 2 for performing hemodialysis, a blood circuit 3 connected to the dialyzer, a dialysis solution circuit 4 connected to the dialyzer, a replacement fluid port 31 provided in the dialysis solution circuit and capable of being opened and closed by a lid member, and a replacement fluid passage 6 having its one end connected to the blood circuit and the other end connected to the replacement fluid port. After a dialysis fluid substitution step of filling the dialysis solution circuit with a dialysis solution, the lid member is detached from the replacement fluid port to change the replacement fluid port from a closed state to an open state. To connect the replacement fluid passage to the replacement fluid port in the open state, a negative pressure forming step to make the pressure in the dialysis solution circuit negative is performed after the dialysis fluid substitution step.

  • Patent number: 9011689
    Abstract: An artificial recharge system and method for recharging an aquifer. The artificial recharge system includes a constructed wetland, a settling pond, and a porous recharge reservoir. The constructed wetland receives water from a surface water source and has aquatic vegetation used to remove sediments and chemicals from the water. The settling pond receives the water from the constructed wetland and provides additional sediment removal. The porous recharge reservoir, which is hydraulically connected to the aquifer, receives the water from the settling pond. The water flows by gravity from the porous recharge reservoir to the aquifer. A backflush tube installed within a sand layer in the porous recharge reservoir is used to remove sediment and particulates from the sand layer.

  • Publication number: 20150090670
    Abstract: A system for treating wastewater is disclosed that includes a series of interconnected reactor tubes. Each reactor tube comprises an outer cathode and an inner anode. The inner anode is positioned within the outer cathode. A voltage differential is applied across the inner anodes and the outer cathodes as wastewater flows between the inner anodes and outer cathodes. As the wastewater flows through the reactor tubes, chlorine based elements are generated to treat the wastewater. The system can include an injector to add chloride salts into the wastewater to generate chlorine based elements. The system can also include a feedback path to divert a portion of the wastewater with chlorine based elements back to the influent wastewater so that the chlorine based elements are mixed with the influent wastewater. The inner anode and the outer cathode can comprise non-donating conductive materials.
