Abstract

The device (100) has control circuits (124,124a) to measure blood buffer parameter of measuring unit selected from group consisting of bicarbonate concentration and carbon dioxide partial pressure. The measured value of blood buffer parameter signal is supplied to control device (125) to regulate actual value of blood buffer parameter to preset value range. The pH measuring unit (150a) is provided in upstream of dialysis unit (105) to supply pH value signal to alarm unit (130) to trigger alarm signal exceeding or falling below specific pH range.

Description

technical field

[0001] The invention relates to a blood purification device having an extracorporeal blood flow path with a blood inlet tube for withdrawing blood from a patient to a dialysis unit and a blood outlet tube from the dialysis unit for returning blood to the patient, The dialysis unit includes an inlet tube for dialysis solution and a dialysate outlet tube. Background technique

[0002] Mammalian organisms function perfectly only when the same physical and chemical conditions are maintained as much as possible. It is especially important to maintain acid-base balance, which is stabilized within narrow physiological ranges by naturally occurring mechanisms in the body. The buffer system consisting of carbonic acid and bicarbonate forms the majority of the blood's total buffering capacity and plays a key role in balancing blood pH fluctuations. Acidic metabolites that are continuously formed in the body are usually neutralized by being excreted by the kidneys or ...
