Problems solved by technology

Although such transplants are often successful in restoring kidney function in patients with kidney disease, this health benefit is limited by the side effects of necessary immunosuppressive therapy
Kidney transplantation is also limited by the availability of transplantable kidneys, and sometimes initially successful transplants fail

Embodiment Construction

[0060] figure 1 A first embodiment of the artificial kidney 1 is schematically shown. It is shown with a housing 3 which may be in tabletop form, wearable on the patient or alternatively implantable in the patient. The housing has a first sterile fluid connection 5 for receiving blood "A" from the patient. The first fluid pathway 7 extends from the first fluid connection 5 to a second sterile fluid connection 9, from which blood "A" can re-enter the patient's blood vessel. The first fluid connection 5 defines the upstream end of the first fluid passage 7 and the second fluid connection 9 defines the downstream end of the first fluid passage 7 . The direction of blood flow "A" is indicated by arrows 11 , 13 , 15 . This blood stream "A" contains, inter alia, blood cells, proteins, creatinine, urea, electrolytes and water. The second fluid passage 17 extends from the first fluid passage 7 from an upstream location 19 and is in fluid communication with the first fluid passage ...

Abstract

Artificial kidney for gradual, and at least semi-continuous, blood treatment, wherein a blood stream is fed from a body of a living human or animal being into the artificial kidney, where anticoagulation is first effected, blood cells and molecules of large and medium molecular weight, such as proteins, are then primarily separated from plasma and fed back to the blood stream, regulating a water and salt balance by diverting excess plasma water and further removing from the blood stream, plasma or plasma water accumulated and toxic substances, by removal of specific electrolytes and waste products and wherein purified or partially purified plasma and plasma water is being carried back to the blood tract of the body.

Description

technical field [0001] The present invention relates to artificial kidneys and, more particularly, to artificial kidneys suitable for progressive and at least semi-continuous blood therapy of preferably ambulatory patients. Background technique [0002] Patients with impaired renal function require frequent hemodialysis. In this dialysis procedure, blood is removed from the patient's body to remove uremic metabolites (nitrogenous protein wastes: such as urea and creatinine), electrolytes, waste products, accumulated substances, toxic substances, and excess fluid while regulating salt concentration. At the same time, the blood returning to the patient's body needs to retain most of the useful substances originally contained in it. There are generally two commonly used methods of dialysis: hemodialysis and peritoneal dialysis. Patients treated with hemodialysis typically need to visit the hospital or dialysis center two to three times a week, where treatment usually takes a...
