摘要： Dialysis systems are disclosed comprising new fluid flow circuits. Systems may include blood and dialysate flow paths, where the dialysate flow path includes balancing, mixing, and/or directing circuits. Dialysate preparation may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit fluid flow paths may be isolated from electrical components. A gas supply in fluid communication with the dialysate flow path and/or the dialyzer able to urge dialysate through the dialyzer and urge blood back to the patient may be included for certain emergency situations. Fluid handling devices, such as pumps, valves, and mixers that can be actuated using a control fluid may be included. Control fluid may be delivered by an external pump or other device, which may be detachable and/or generally rigid, optionally with a diaphragm dividing the device into first and second compartments.

摘要： An adaptation device is used for coupling at least one sensor to a tube shell wall of a tube for measuring a property of a fluid conveyed through the tube. The adaptation device has an adapter passage opening for providing a fluid connection via a tube shell wall passage opening between a tube lumen and the sensor. A sensor receptacle is used to accommodate the sensor in the region of the adapter passage opening. An adapter sealing portion extends around the adapter passage opening for circumferential sealing of the adaptation device around the adapter passage opening with respect to the tube shell wall. This results in an adaptation device which makes sensors which are basically suitable for measuring a fluid property of fluid conveyed through a tube accessible for such fluid measurement within a sensor device.

摘要： Graphical user interfaces for use with extracorporeal blood treatment systems may include a plurality of mini settings cards corresponding to a plurality of settings cards. The mini settings cards may display one or more user-interactable settings, and may be selected to display the corresponding settings card. Further, each settings card may be accessed in other ways to selection of mini settings card such as, for example, by selection of a process feature graphical element corresponding the settings card.

摘要： A fluid collecting container includes a fluid inlet, a fluid outlet, a front sheet and a back sheet. The front sheet and back sheet are fixed together at their edges and create a chamber in which the fluid can be collected. The fluid collecting container also has a channel having a first upper end fluidically connected to the fluid inlet and a second bottom end fluidically connected to the chamber. The channel is configured to increase the pressure drop at the fluid inlet once the fluid level in the chamber reaches the second bottom end.

摘要： The present invention generally relates to hemodialysis and similar dialysis systems, including a variety of systems and methods that would make hemodialysis more efficient, easier, and/or more affordable. One aspect of the invention is generally directed to new fluid circuits for fluid flow. In one set of embodiments, a hemodialysis system may include a blood flow path and a dialysate flow path, where the dialysate flow path includes one or more of a balancing circuit, a mixing circuit, and/or a directing circuit. Preparation of dialysate by the preparation circuit, in some instances, may be decoupled from patient dialysis. In some cases, the circuits are defined, at least partially, within one or more cassettes, optionally interconnected with conduits, pumps, or the like. In one embodiment, the fluid circuit and/or the various fluid flow paths may be at least partially isolated, spatially and/or thermally, from electrical components of the hemodialysis system. In some cases, a gas supply may be provided in fluid communication with the dialysate flow path and/or the dialyzer that, when activated, is able to urge dialysate to pass through the dialyzer and urge blood in the blood flow path back to the patient. Such a system may be useful, for example, in certain emergency situations (e.g., a power failure) where it is desirable to return as much blood to the patient as possible. The hemodialysis system may also include, in another aspect of the invention, one or more fluid handling devices, such as pumps, valves, mixers, or the like, which can be actuated using a control fluid, such as air. In some cases, the control fluid may be delivered to the fluid handling devices using an external pump or other device, which may be detachable in certain instances. In one embodiment, one or more of the fluid handling devices may be generally rigid (e.g., having a spheroid shape), optionally with a diaphragm contained within the device, dividing it into first and second compartments.

摘要： A method includes detecting a beginning of a donation process; in response to detecting the beginning of the donation process, providing an output; determining an amount of time remaining for the donation process; in response to detecting the amount of time remaining for the donation process, updating the output; detecting a loss in pressure; in response to detecting the loss in pressure, updating the output; detecting an ending of the donation process; and in response to detecting the ending of the donation process, updating the output. The donation process may include a plasma donation using an apheresis machine. The detecting the beginning of the donation process may include detecting a flow of fluid. The output may include one or more of a light and a sound. The output may be provided on a side of an apheresis machine.
