| Popis: |
A hemodialysis system consists of a blood circuit, a dialysate circuit and the dialyser. The blood circuit includes a vascular access device, blood tubes, one or two blood pumps, pressure and air-leak monitors and security clamps. A separate pump delivers anticoagulants to prevent clotting in the extracorporeal blood circuit. The dialysate circuit requires at least one or two dialysis fluid pumps, and systems for ultrafiltration control and heating of the dialysis fluid. The composition of the dialysis fluid, the flow rates and pressures, and the presence of blood in the dialysate are continuously monitored. Most devices designed for routine maintenance hemodialysis provide water purification, degassing and preparation of the dialysate from purified water and electrolyte/buffer concentrates. |
