摘要:
A container for use with a hemodialysis apparatus having a vent structure is described. The vent structure is porous, and allows air in the container to vent when the container is being filled with fluid, but expands when the vent structure becomes wet, when filling is complete, thereby closing off the pores and inhibiting (e.g., preventing) fluid from flowing through the vent structure, and reentry of air into the container. The vent structure can also include a micro-porous membrane.
摘要:
A method for cleaning a drain line of a dialysis machine downstream of a filtration unit. The method includes closing inlet and outlet valves of the filtration unit, and closing a bypass valve along a bypass line that connects a source line to a drain line. The method also includes configuring the balancing chamber such that flow is permitted only via the drain line, flowing an amount of a cleaning agent into the drain line through a cleaning agent valve, and rinsing the cleaning agent from the drain line with a rinse fluid.
摘要:
This invention relates to dialysis systems and methods. In some implementations, a method includes applying vacuum pressure to a device of a dialysis system, and then determining, based on a detected fluid level or measured pressure, whether the device is functioning properly.
摘要:
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.
摘要:
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.
