  • Patent number: 10507275
    Abstract: A tube set for a blood handling apparatus, in particular an extracorporeal blood handling apparatus with an extracorporeal blood circuit or an apparatus for peritoneal dialysis, and a blood handling apparatus that has such a tube set are described. The tube set includes a device for collecting particles provided in a tube line portion of the tube set downstream of the tube portion placed in the occluding hose pump. The device for collecting particles prevents retention of solid substances that are possibly contained in the dialysis fluid, substituate or peritoneal solution. The tube set also has a device for limiting the pressure in the tube line portion between the occluding hose pump and the device for collecting particles. The device for limiting the positive pressure prevents an excessive positive pressure from building up in the tube line when fluid flow through the device for collecting particles is reduced or interrupted.

  • Patent number: 10488244
    Abstract: A self-filling graduated cylinder system for efficiently filling a graduated cylinder with a chemical solution. The self-filling graduated cylinder system generally includes a graduated cylinder having an interior, an upper end, an upper opening in the upper end a lower end opposite of the upper end, and a check valve attached to the graduated cylinder near the lower end of the graduated cylinder. The check valve is adapted to allow a liquid chemical to flow upwardly through the check valve into the graduated cylinder and to prevent the liquid chemical within the interior of the graduated cylinder from flowing downwardly through the check valve. A vacuum device is fluidly connected to the graduated cylinder to draw the liquid chemical upwardly to an upper level within the graduated cylinder. Alternatively, a pump device pumps liquid chemical into the graduated cylinder.

  • Patent number: 8871062
    Abstract: An apparatus and method are disclosed for controlling the thickness of a flowing, laminar fluid film. The film flow may be gravity-induced or the result of an alternative force. The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. For example, in some applications, it may be desirable to maintain an approximately constant film thickness as the fluid flows over the active region of the surface. The geometry of the flow surface is used to obtain the desired control over the fluid film thickness. The flow surface is the outer surface of a solid with a closed upper end and a lower end that may be open or closed.

  • Publication number: 20140299525
    Abstract: An apparatus for treating fluid in a main reservoir includes an auxiliary reservoir and filter located outside the main reservoir. Ozonated air bubbles are injected by a diffuser into a lift tube containing fluid from the main reservoir. The fluid flows up the lift tube and into the auxiliary reservoir due to the expansion of the ozonated air bubbles as they go up the lift tube. Fluid flow to and from the main reservoir is via conduits normally used to connect the main reservoir to a conventional high pressure water pump and filter, with check valves added to prevent backflow to/from the auxiliary reservoir and lift tube when the water pump is on. When the water pump is off, the fluid is caused to pass through the auxiliary reservoir and filter and back into the main reservoir as a result of the flow of ozonated air in the lift tube.

  • Publication number: 20140298715
    Abstract: Provided is a gravitational settling tank capable of detecting a boundary surface of a solids-enriched fluid. A pressure vessel 11 is provided with a multipoint temperature sensor 18 including two or more thermocouples 17 to measure the temperature of an internal fluid in the pressure vessel 11. Two or more temperature measuring junctions 17a of the thermocouples 17 are arranged in the pressure vessel 11 so as to be immersed in the internal fluid and positioned at different heights from one another. The boundary surface of the solids-enriched fluid is detected based on the temperature distribution of the internal fluid in the pressure vessel 11, where the temperature distribution is determined with the multipoint temperature sensor 18.

  • Patent number: 8852140
    Abstract: Systems and methods are provided for automatically adjusting the operational parameters of a blood separation procedure. A blood separation device has an inlet for passing fluid thereinto and an outlet for removing fluid therefrom. A pump system is provided for moving fluid into and out of the device. In use, blood is conveyed into the device, where platelets are separated from at least a portion of the blood. A controller determines the amount of platelets in the device. Based at least in part on the amount of platelets in the device, corrective action is taken to avoid platelet aggregation in the device. The corrective action may be conveying an elevated amount of anticoagulant into the blood and/or the device and may be initiated when the determined amount of platelets approaches, meets, or exceeds a threshold predicted likelihood of platelet aggregation.

  • Publication number: 20140262984
    Abstract: A method of assessing biofilm thickness in a membrane supported biofilm reactor (MSBR) of the type comprising a lumen containing a gas phase, a liquid phase, and a gas permeable membrane providing an interface between the gas and liquid phases, the method comprising the steps of charging the lumen with an inert gas, closing the lumen to establish an initial elevated pressure in the lumen, measuring the rate of change of pressure within the lumen, and correlating the rate of change of pressure (dP/dt) with biofilm thickness. The step of correlating dP/dt with biofilm thickness involves correlating dP/dt with the rate of diffusion of the inert gas (dn/dt), correlating dn/dt with an overall mass transfer coefficient (K), correlating K with the mass transfer coefficient of the biofilm (ICB), and correlating k? with the biofilm thickness.
