Embodiment Construction

[0062] The examples described herein are applicable to any medical fluid therapy system that delivers medical fluids such as blood, dialysis fluid, replacement fluid, purified or sterile water, liquid concentrates, or intravenous drugs. These examples are particularly suitable for renal failure therapies such as all forms of hemodialysis (HD), plasmapheresis, hemofiltration (HF), hemodiafiltration (HDF), continuous renal replacement therapy (CRRT), apheresis, autologous Blood transfusion, hemofiltration for sepsis, and extracorporeal membrane oxygenation (ECMO) therapy are collectively or individually referred to herein as extracorporeal therapy. Furthermore, the systems and methods described herein can be used in clinical or home settings. In the following example, an extracorporeal therapy system 10a is depicted as a renal failure therapy system having a machine 12 that generates on-line dialysis fluid for therapy.

[0063] now refer to Figure 1A , shows one embodiment of...

Abstract

An extracorporeal therapy system includes: (i) a dialysis fluid circuit including dialysis fluid preparation structure configured to prepare a dialysis fluid for an extracorporeal therapy treatment; (ii) a blood circuit including a blood filter for use during the extracorporeal therapy treatment; (iii) a blood pump operable to pump blood through the blood circuit and blood filter; and (iv) a control unit operable with the dialysis fluid preparation structure and the blood pump, the control unit programmed to prepare a gas generation fluid different than the dialysis fluid for the extracorporeal therapy treatment, wherein the gas generation fluid generates carbon dioxide ("CO2") gas, and wherein the CO2 gas is used to prime the blood circuit including the blood filter.

Description

technical field [0001] The present disclosure relates generally to medical delivery. More specifically, the present disclosure relates to perfusion of extracorporeal therapy machines. Background technique [0002] A person's kidney system can fail for various reasons. Kidney failure produces several physiological disturbances. Kidney failure results in an inability to balance water and minerals or excrete the daily metabolic load. Toxic end products of metabolism (urea, creatinine, uric acid, and others) may accumulate in the blood and tissues. [0003] Kidney failure and decreased kidney function have been treated with dialysis. Dialysis removes waste, toxins, and excess water from the body that would otherwise be removed by the kidneys when they are functioning properly. Dialysis treatment, which replaces kidney function, is vital for many people because it saves lives. [0004] One type of kidney failure therapy is hemodialysis ("HD"), which typically uses diffusion...
