  • Publication number: 20240216594
    Abstract: Systems and methods are described for adapting dialysis solution bags between different modalities of dialysis treatment. Specifically, for example, the system described herein enables an automated peritoneal dialysis (APD) patient to use APD bags from their existing stock for a manual exchange treatment, such as a continuous ambulatory peritoneal dialysis (CAPD) treatment, thereby providing that the APD patient no longer needs to retain manual exchange bags and sets in the event of an emergency or other situation requiring the performing of manual dialysis exchanges.

  • Patent number: 11400015
    Abstract: The present disclosure describes a kit for peritoneal dialysis that includes at least two bags. The kit also includes an overwrap for accommodating the at least two bags. At least one bag of the at least two bags forms at least a portion of the overwrap. According to the present disclosure, it is advantageously possible to reduce the material consumption of the overwrap, lower the cost of the kit, and reduce the amount of the disposable waste.

  • Publication number: 20200061272
    Abstract: A peritoneal dialysis concentrate comprises an all-in-one concentrate or at least two concentrate parts to be stored separately before use, wherein by a diluting solution, the all-in-one concentrate can be diluted or dissolved, or the at least two concentrate parts can be diluted or dissolved, and mixed with each other to obtain the peritoneal dialysis solution suitable for peritoneal dialysis treatment. Also a single-chamber peritoneal dialysis bag, a dual-chamber peritoneal dialysis bag and a multi-chamber peritoneal dialysis bag contain the peritoneal dialysis concentrate. In addition, a set for a continuous ambulatory peritoneal dialysis and a set for an automated peritoneal dialysis comprise the single-chamber peritoneal dialysis bag or the dual-chamber peritoneal dialysis bag or the multi-chamber peritoneal dialysis bag, which contains the peritoneal dialysis concentrate.

  • Patent number: 10398826
    Abstract: A pressure output device (POD) assembly for sensing fluid pressure in a fluid processing system, is provided. This POD assembly includes a shell defining a shell interior, and a movable diaphragm disposed in the shell interior and separating the shell interior into a flow-through chamber and a pressure sensing side. A sensor port is in fluid communication with the pressure sensing side. An inlet port and an outlet port are in fluid communication with the flow-through chamber. The inlet port and the outlet port define an inlet and an outlet, respectively, of a flow-through channel that passes through the flow-through chamber. A boss protrudes from the interior wall of the shell and extends into the flow-through channel to prevent occlusion of flow under different pressure conditions within the flow-through chamber.
