Abstract
The present disclosure concerns a method for preparing an extracorporeal blood circuit for its use in a blood treatment of a patient, which treatment is carried out using a blood treatment apparatus and using a blood treatment device, which comprises a blood chamber and a dialysate chamber partitioned off therefrom by a membrane, The method comprising: filling the extracorporeal blood circuit using a priming solution, wherein the priming solution comprises citrate, or filling of the extracorporeal blood circuit using a priming solution and using a citrate solution. The invention further comprises devices suitable for carrying out the method.
Claims16
A method of preparing an extracorporeal blood circuit for use in a blood treatment of a patient, which treatment is carried out using a blood treatment apparatus and using a blood treatment device, which comprises a blood chamber and a dialysate chamber partitioned off therefrom by a membrane, the method comprising:
- filling the extracorporeal blood circuit with a first priming solution, wherein the first priming solution comprises citrate, or filling the extracorporeal blood circuit with a second priming solution and a citrate solution;
- and
- filling the extracorporeal blood circuit with a fluid comprising or consisting of blood while no dialysis fluid flows through the dialysate chamber of the blood treatment device.
A control or regulating unit suitable and provisioned, designed, configured, or programmed for carrying out a method comprising:
- preparing an extracorporeal blood circuit for use in a blood treatment of a patient, which treatment is carried out using a blood treatment apparatus and using a blood treatment device, which comprises a blood chamber and a dialysate chamber partitioned off therefrom by a membrane;
- filling the extracorporeal blood circuit with a first priming solution, wherein the first priming solution comprises citrate, or filling the extracorporeal blood circuit with a second priming solution and a citrate solution;
- and
- filling the extracorporeal blood circuit with a fluid comprising or consisting of blood while no dialysis fluid flows through the dialysate chamber of the blood treatment device.
A blood treatment apparatus, comprising a control or regulating unit, which is programmed to carry out a method comprising:
- preparing an extracorporeal blood circuit for use in a blood treatment of a patient, which treatment is carried out using a blood treatment apparatus and using a blood treatment device, which comprises a blood chamber and a dialysate chamber partitioned off therefrom by a membrane;
- filling the extracorporeal blood circuit with a first priming solution, wherein the first priming solution comprises citrate, or filling the extracorporeal blood circuit with a second priming solution and a citrate solution;
- and
- filling the extracorporeal blood circuit with a fluid comprising or consisting of blood while no dialysis fluid flows through the dialysate chamber of the blood treatment device.
