Abstract: Methods and systems of detection of presence in and delivery to location are provided. A method detects a presence of a mobile device within a perimeter of a geographic region. The method searches a database to determine whether the first mobile device is associated with any existing account. Responsive to determining that the mobile device is associated with a first account, the method searches the database to determine whether there is any pending task associated with the first account. Responsive to determining that there is a pending task associated with the first account, the method transmits a first message indicating the detection of presence of the mobile device associated with the first account. The method determines that the mobile device is at least approximately at a first location of a plurality of predefined locations within the perimeter. The method transmits information associated with the first location to the computing device.

Abstract: An extracorporeal blood treatment apparatus includes a blood treatment unit, a treatment fluid circuit, and a blood circuit. The treatment fluid circuit has a treatment fluid pump for circulating treatment fluid around the treatment fluid circuit and through the blood treatment unit. The blood circuit has a dual chamber blood pump for circulating blood around the blood circuit and through the blood treatment unit. An arterial line withdraws blood from a patient and delivers the withdrawn blood to the blood treatment unit. A venous line returns the treated blood to the patient. The arterial and venous lines can be switched between a first condition in which they are connected to the patient and a second condition in which they are disconnected from the patient and connected to each other for recirculation of blood through the blood circuit.

Abstract: A dialysate fluid circulation apparatus includes a dialyzer, a first housing and a second housing. The first housing contains material capable of releasing sodium into dialysate fluid flowing through the first housing. The second housing contains material capable of binding sodium ions from dialysate fluid flowing through the second housing. Hydraulic conduit sections are configured to extend between the dialyzer, the first housing, and the second housing to connect the dialyzer with the housings in a primary flow path for dialysate fluid to flow from the dialyzer to the first housing, from the first housing to the second housing, and from the second housing back to the dialyzer.

In the apparatus for delivering saline to a patient after dialysis treatment has ended, a controller is configured to automatically deliver saline after dialysis treatment has concluded, but before the patient is disconnected in response to a request. In the apparatus for alerting a patient that dialysis treatment is about to end, a controller is configured to monitor a dialysis treatment and activate an alarm when treatment is about to end.

Abstract: Systems and methods for extracorporeal processing of blood or other body fluid for the treatment of conditions, such as sepsis, autoimmune disease, or toxemia related to kidney failure, liver failure, or drug overdose are provided. In an extracorporeal treatment system, a fraction of a body fluid is passed into a treatment fluid, at least a portion of which is then passed through a sorbent suspension reactor for treatment by a sorbent suspension. The treatment fluid circuit can be maintained at a fixed volume, which enables accurate fluid balance between the patient and the extracorporeal circuit. Some or all of the treatment fluid, optionally also containing nutrients and/or therapeutic agents, is returned to the patient. In a peritoneal dialysis system, dialysate is passed into a patient's peritoneal cavity, recovered from the cavity, passed through a sorbent suspension reactor in accordance with the invention, and returned to the cavity.
