Specification
- The 4008S Next Generation has been developed to provide safety and efficiency for all important treatment modalities within the scope of renal replacement therapies. This includes:
- Bicarbonate or acetate dialysis
- Single-needle or single-needle click-clack
- Ultrafiltration and sodium profiles
- Isolated ultrafiltration / Bergström treatment
- The automated acquisition, monitoring and control of specific patient and machine parameters with the 4008S Next Generation provides the operator with continuous and precise assessment of the current treatment situation.
Key features of the 4008S Next Generation include:
- Monitoring of dialysis dose by OCM® (Online clearance monitoring and plasma sodium measurement)
- Treatment with ultrapure dialysis fluid (DIASAFE®plus filter)
- Use of hygienic, dry bicarbonate concentrate (Bibag®)
- Single-needle method
- Connection for central concentrate supply
In addition, the following therapeutic tools are available:
- Blood pressure monitor (BPM)
- Easy data management with patient card (offline) or network integration (online)
