Embodiment Construction

[0072] specific implementation

[0073] refer to figure 1 and figure 2, a peritoneal dialysis (“PD”) system includes a base PD system 101 and a peritoneal dialysis fluid exchange system 201 . The peritoneal dialysis fluid exchange system 201 operates independently of the base PD system 101 and can be physically remote from the base PD system 101 during operation. For example, in some embodiments, a peritoneal dialysis fluid exchange system is used to provide daytime fluid exchange at work or school as part of peritoneal dialysis. The peritoneal dialysis fluid exchange system includes a peritoneal dialysis fluid exchange device (eg, PD fluid exchange device) 202 and a simplified medical fluid cassette (eg, fluid exchange cassette) 212 . Relative to PD cycler 102, PD fluid exchange device 202 is small and lightweight so that it can be easily transported. In some cases, PD fluid exchange device 202 is sized to be hand-held. In addition, the PD fluid exchange device 202 incl...

Abstract

A peritoneal dialysis system includes a base peritoneal dialysis system and a peritoneal dialysis fluid exchange system that operates independently of the base system. The base system includes a first cassette including a first patient line configured to be connected to a patient, and a PD cycler. The PD cycler receives the first cassette, and includes a pump that cooperates with the first cassette to deliver dialysate to and drain dialysate from a peritoneal cavity of the patient via the first patient line. The peritoneal dialysis fluid exchange system includes a second cassette including a second patient line configured to be connected to the patient and a fluid exchange device that receives the second cassette. The fluid exchange device includes a data exchange interface operable to transfer patient treatment data from the peritoneal dialysis fluid exchange system to the base peritoneal dialysis system.

Description

[0001] This application is a divisional application of an invention patent application with an application date of December 23, 2013, an application number of 201380074424.6, and an invention title of "peritoneal dialysis system and related devices and methods". technical field [0002] The present invention relates to peritoneal dialysis systems and related devices and methods. Background technique [0003] Dialysis is a treatment used to support patients with insufficient kidney function. The two main methods of dialysis are hemodialysis and peritoneal dialysis. [0004] During hemodialysis ("HD"), a patient's blood is passed through the dialyzer of a dialysis machine while dialysis solution, or dialysate, is also passed through the dialyzer. The semipermeable membrane in the dialyzer separates blood from the dialysate within the dialyzer and allows diffusion and osmotic exchange to occur between the dialysate and blood streams. These exchanges across the membrane result...
