Problems solved by technology

[0004] This is even more important in pediatric patients, as these patients may experience less blood cell loss than other patients and have smaller total blood values, so retransfusion of the replacement product may be more hazardous than other patients

Embodiment Construction

[0207] During or after a blood therapy session, the blood or blood mixture in the extracorporeal blood circuit, in particular the blood filter, is usually returned to the patient. This is usually done by introducing a substitute into the extracorporeal blood circuit, whereby the blood present therein is displaced downstream and thus reinfused into the patient, for example via a venous patient connection.

[0208] In some cases, due to the introduction of the substitute, a diffuse transition zone is formed from the blood to the substitute, where the blood mixes with the substitute. Therefore, the blood / replacement mixture present downstream of the blood filter (post-filter) usually contains the replacer. A large volume of replacement may be required to flush the entire extracorporeal blood circuit up to the venous patient connection. Additionally, some of this replacement is reintroduced into the patient, which is often undesirable, especially in dialysis patients.

Abstract

A method for operating a blood treatment apparatus including an extracorporeal blood circuit having a blood filter with a blood chamber and a dialysate chamber, between which a membrane is arranged. The method encompasses operating a blood pump from a first time point, at which an ultrafiltration pump is stopped, at least until a second time point, at which at least one of the following conditionsis met for the first time after the first time point: a time interval after has elapsed, the blood pump has conveyed a volume after, a measurement of a fluid in the extracorporeal blood circuit exceeds or falls below a threshold.

Description

technical field [0001] The present disclosure relates to a method for operating a blood treatment apparatus for blood treatment of a patient. It also relates to a control unit, a medical treatment device for carrying out the method, a digital storage medium, a computer program product and a computer program. Background technique [0002] During or after extracorporeal blood therapy, the blood present in the extracorporeal circuit is usually displaced from the extracorporeal blood circuit in the direction of the patient's vascular system by means of a replacement fluid (hereinafter also referred to as replacement) and thus reinfused into the patient. It is often desirable to re-infuse as much patient blood in a blood therapy facility as possible in order to minimize loss of valuable blood cells and other blood components. However, when the blood is reinfused, a certain amount of replacement is injected into the patient. [0003] Since removal of some of the fluid component ...
