In general, a dialysis device includes a first processing device for monitoring dialysis functions of the dialysis device, a second processing device, a display device, and memory. The memory is configured to store instructions that, when executed, cause the dialysis device to provide, on the display device, a first display region and a second display region, where the first display region is associated with the first processing device and the second display region is associated with the second processing device. At least a portion of the first display region cannot be obscured by the second display region.

User interfaces for dialysis devices

A system for controlling the position of a diaphragm in a diaphragm-containing pressure pod, is provided. The system can include a peristaltic pump, a pressure pod having a flow-through fluid side and a gas side that are separated by a diaphragm, and a pressure sensor operatively connected to the gas side. The pressure sensor is configured to sense pulses of pressure resulting from movement of the diaphragm and caused by the action of the peristaltic pump. A gas source and a valve can be in fluid communication with the gas side of the pressure pod and can be configured to provide gas to, or vent gas from, the gas side. A controller receives pressure signals from the pressure sensor and controls the valve in response, and in so doing, controls the position of the diaphragm. Methods for positioning the diaphragm are also included.

Automatic detection and adjustment of a pressure pod diaphragm

According to at least one example embodiment, a system of monitoring blood leaks during hemodialysis therapy includes a wetness sensing device and a hemodialysis machine. The wetness sensing device is configured to transmit information wirelessly, the information being indicative of an absence of a liquid or a presence of a liquid. The hemodialysis machine includes, or is coupled to, a wireless receiver having two or more antennas. Signals received at the two or more antennas are decoded at the wireless receiver. If decoded signals indicate a detected wetness, the hemodialysis machine is caused to halt blood flow in and out of the machine and generate an alarm.

This patent application relates generally to processing devices in the medical device area.

User interface processing device

A vent assembly is described for use in an extracorporeal fluid unit. A vent structure adjacent to a micro-porous membrane forms the assembly. The vent structure is porous and changes color when the vent structure becomes wet, thereby providing a visual indication that the vent structure has been exposed to liquid.

Extracorporeal fluid circuit and related components

A method for inlet temperature monitoring for centralized heat disinfection of dialysis machine inlet lines is described. The method can be used, for example, for a dialysis system which has a central water processing system used at a multiple patient dialysis treatment clinic or center. A central water processing system and a plurality of dialysis machines having fluid inlets are fluidly connected to a water supply loop which circulates heated water from the central water processing system to the dialysis machines and back to the central water processing system. A dialysis system for centralized heat disinfection of dialysis machine inlet lines of dialysis machines supplied with water by a central water processing system also is provided.

In general, this disclosure relates to extracorporeal fluid circuits. In some aspects, an air-release device for allowing air to be released from a liquid in extracorporeal circuitry includes an elongate chamber having a bottom region and a top region and a fluid entry port and fluid exit port at or near the bottom region. The air release device also includes a vent structure at or near the top region of the elongate chamber that includes a porous material capable of swelling when moistened such that the vent structure can inhibit liquid from escaping the air-release device during use.
