Blood set component connection detection

Extracorporeal blood treatment systems and methods to detect the connection of one or more components (e.g., of an extracorporeal blood set) thereto (e.g., to one or more pressure transducers contained in the system housing) by, for example, controlling an air pump apparatus to provide air to a connection port at which the component is to be connected and monitoring pressure resulting therefrom to detect whether the component is operatively connected (e.g., based on a detected change in the monitored pressure due to the increased resistance, based on a monitored rate of decay of pressure of injected air, etc.).

Systems, methods, and apparatuses for monitoring end stage renal disease

An end stage renal disease (ESRD) monitoring system may include an implantable sensor and a reader device with an optical sensor. The implantable sensor may be configured to detect a group of analytes relevant to ESRD, such as glucose, creatinine, urea, and potassium. The implantable sensor may be implanted into the dermis of an animal, and may exhibit color changes in response to the presence of the target analytes or reaction product(s) thereof. The reader device may be configured to capture an image of the implanted sensor and to determine the concentration of the target analytes based at least in part on the image. The reader device may be a personal electronic device such as a cell phone, PDA, or personal computer.

Patient line blockage detection

A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a pressure sensor mounted at a proximal end of a patient line made of a distensible material that provides PD solution to a patient through a catheter. During treatment, an occlusion can occur at different locations in the patient line and/or the catheter. When an incremental volume of additional solution is provided to the patient line while the occlusion is present, a change in pressure results. The change in pressure depends on dimensions and a distensibility of a non-occluded portion of the patient line. If the change in pressure, the incremental volume, properties related to the distensibility of the patient line, and some of the dimensions of the patient line are known, a location of the occlusion can be inferred. An occlusion type can be inferred based on the location of the occlusion.

Pump cassette and methods for use in medical treatment system using a plurality of fluid lines

A fluid handling cassette, such as that useable with an automated peritoneal dialysis (APD) cycler device or other infusion apparatus, may include a generally planar body having at least one pump chamber formed as a depression in a first side of the body and a plurality of flowpaths for a fluid that includes a channel. A patient line port may be arranged for connection to a patient line and be in fluid communication with the at least one pump chamber via at least a first one of said flowpaths, and an optional membrane may be attached to the first side of the body over the at least one pump chamber. In one embodiment, the membrane may have a pump chamber portion with an unstressed shape that generally conforms to the depression of the at least one pump chamber in the body and is arranged to be movable for movement of the fluid in a useable space of the at least one pump chamber. One or more spacers may be provided in the at least one pump chamber to prevent the membrane from contacting an inner wall of the at least one pump chamber. The patient line, a drain line, and/or a heater bag line may be positioned to be separately occludable in relation to one or more solution lines that are connectable to the cassette.
