International Classification:

B01D 24/00
B01D 11/00

US Classification:

210646, 210645, 2103231, 604321, 604405

Abstract:

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.

US Classification:

422 3, 210636, 210645, 210646, 210764, 210767, 422105

Abstract:

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.

International Classification:

B01D 61/32

US Classification:

210767, 210188

Abstract:

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, but expands when the vent structure becomes wet, thereby closing off the pores and inhibiting (e.g., preventing) fluid from flowing through the vent structure. The vent structure also protects the membrane from becoming wet, such as from condensation.

International Classification:

B01D 61/30

US Classification:

210 85

Abstract:

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.

International Classification:

G09G 5/00

US Classification:

345156

Abstract:

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.
