System and method for automated data collection of twenty-four hour ultrafiltration and other patient parameters using wired or wireless technology

#The present disclosure relates to medical fluid delivery and in particular to peritoneal dialysis fluid delivery.

#Due to disease or other causes, a person's renal system can fail. In renal failure of any cause, there are several physiological derangements. The balance of water, minerals and the excretion of daily metabolic load is no longer possible in renal failure. During renal failure, toxic end products of nitrogen metabolism (urea, creatinine, uric acid, and others) can accumulate in blood and tissues.

#Kidney failure and reduced kidney function have been treated with dialysis. Dialysis removes waste, toxins and excess water from the body that would otherwise have been removed by normal functioning kidneys. Dialysis treatment for replacement of kidney functions is critical to many people because the treatment is life saving. One who has failed kidneys could not continue to live without replacing at least the filtration functions of the kidneys.

#FIG. 1 is a perspective view of one embodiment of an automated peritoneal dialysis machine (“APD”), and in particular a peritoneal dialysis machine used to perform a nighttime dialysis treatment.

#FIG. 2 is a schematic view of one embodiment of a remote exchange device (“RED”) used to perform a midday exchange for the patient.

#FIG. 3 is a schematic view of one embodiment of the system and accompanying method of the present disclosure.

#Dialysis Machine

#Referring now to the drawings and in particular to FIG. 1, a data collection system 100 uses a dialysis machine 10. System 100 is applicable generally to any type of renal failure therapy system, such as peritoneal dialysis (“PD”), hemodialysis (“HD”), hemofiltration (“HF”), hemodiafiltration (“HDF”) and continuous renal replacement therapy (“CRRT”). System 100 could also be used outside of the renal field, such as for medication delivery in general and for blood processing. For ease of illustration, however, system 100 is described in general as a dialysis system, and in one particularly well-suited application as a PD system.

#Dialysis instrument 10 is configured for whichever type of renal failure therapy system is used. Dialysis instrument 10 includes a central processing unit (“CPU”) and a plurality of controllers (e.g., safety, valve, heater, pump, video and audio (e.g., voice guidance) controllers) operable with the CPU. The CPU operates with a graphical user-machine interface (“GUI”), e.g., via the video controller. The GUI includes a video monitor 20 and one or more type of input device 22, such as a touch screen or electromechanical input device (e.g., membrane switch). The CPU also operates with a wireless communicator 15 and/or receives data from a memory device port 25, such as a USB flash drive or travel drive port, discussed in more detail below.
