Constructive layout in a container, to provide clean areas for medical and hospital care, such as fractionation of solid and liquid oral drugs (ISO8) and handling of sterile drugs (ISO7), as well as the configuration of the containers for the infusion, diagnosis, surgery, ICU and hemodialysis areas.

Dialysis systems comprising actuators that cooperate to perform dialysis functions and sensors that cooperate to monitor dialysis functions are disclosed. According to one aspect, such a hemodialysis system comprises a user interface model layer, a therapy layer, below the user interface model layer, and a machine layer below the therapy layer. The user interface model layer is configured to manage the state of a graphical user interface and receive inputs from a graphical user interface. The therapy layer is configured to run state machines that generate therapy commands based at least in part on the inputs from the graphical user interface. The machine layer is configured to provide commands for the actuators based on the therapy commands.

A degassing module that may be used in conjunction with a sorbent regeneration cartridge is described. The degassing module may include an air inlet port, a fluid outlet port, a gas outlet port, first and second channels located in an interior chamber, a port connecting the first and second channels, and a hydrophobic membrane positioned above the second channel. The first channel may be in fluid communication with the air inlet port and the second channel may be in communication with the fluid outlet port. In some embodiments, each of the first and second channels may have a spiral configuration.

A portable hemodialysis system is provided including a dialyzer, a closed loop blood flow path which transports blood from a patient to the dialyzer and back to the patient, and a closed loop dialysate flow path which transports dialysate through the dialyzer. In addition, the hemodialysis system includes two reservoirs which can be alternately placed in the dialysis flow path using various controllable fluid valves. The weight, and therefore the level of dialysate, of each reservoir is measured by a preferred level sensor having a strain measuring device which includes a load cell and a tilt sensor. The load cell and tilt sensor are electrically connected to a processor for sending force and tilt measurements to the processor. The processor may analyze the tilt measurements to correct for any inaccurate measurements of the load cell caused by the tilt.

A vascular access device with arteriovenous fistula support includes a top portion and a bottom portion. The top portion has a partial artery channel, a partial vessel channel, and a partial arteriovenous joint between the partial artery channel and the partial vessel channel, where the partial vessel channel has a vascular access aperture for exposing the vessel. The bottom portion has a corresponding partial artery channel, partial vessel channel, and partial arteriovenous joint between the partial artery channel and the partial vessel channel. When the top portion is coupled to the bottom portion, the two partial artery channels couple together to form an artery channel, the two partial vessel channels couple together to form a vessel channel, and the two partial arteriovenous joints couple together to form an arteriovenous joint for an arteriovenous fistula.

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.

The invention relates to a communications device for non-electric communication between fluidically interconnected devices, the communications device being designed to be mounted in a position in a fluidic overall system formed by the fluidically interconnected devices and to receive and/or emit non-electric signals, in particular in the form of pressure or sound signals, the non-electric signals being transmitted via a line that fluidically interconnects the devices. The invention further relates to a method for non-electric communication between fluidically interconnected devices, the non-electric communication taking place preferably by means of pressure and/or sound signals via at least one line that fluidically interconnects the devices.
