Embodiment Construction

[0041] figure 1

[0042] Reference figure 1 An embodiment of the blood treatment apparatus 2 used for extracorporeal blood treatment such as dialysis is explained. The blood processing equipment 2 (dialysis machine) includes a blood processing unit 20 and a blood line 40 with a blood pump 44, the blood line being configured to draw blood from the blood source 13 and pass the blood through the blood processing unit 20 (in which blood is processed) , And deliver the processed blood to the target container 14.

[0043] In the blood processing unit 20, there is a semipermeable membrane 27, and the semipermeable membrane 27 divides the blood processing unit 20 into a blood compartment 26 having a blood inlet 21 and a blood outlet 22, and a treatment with a liquid inlet 23 and a liquid outlet 24 Liquid compartment 25. The membrane 27 allows the treatment fluid to interact with blood in a manner known in the art.

Abstract

A blood treatment apparatus adapted to preserve a blood treatment unit (20) between blood treatment sessions. The blood treatment apparatus is configured to i) perform a blood treatment session and thereby use the blood treatment unit (20), ii) fill the blood treatment unit (20) with a preservation fluid comprising at least one treatment fluid concentrate of a type that is used to prepare the treatment fluid, iii) maintain the preservation fluid in the blood treatment unit (20) until a next blood treatment session is prepared, iv) dispatch the preservation fluid from the blood treatment unit (20) in preparation of a next blood treatment session, and v) perform a next blood treatment session and thereby extend the use of the blood treatment unit (20). A related method is also described.

Description

Technical field [0001] The present invention mainly relates to a blood processing device and a method for the blood processing device to store its components. Background technique [0002] Nowadays blood processing equipment has been used for extracorporeal blood treatment, which involves drawing blood from a patient, processing the blood, and returning the treated blood to the patient. For this purpose, extracorporeal blood flow circuits (blood lines) are used, which are usually connected to the patient's vascular access via one or more access devices such as needles or catheters inserted into the patient's blood vessel. Depending on the method of blood treatment, blood can be drawn from the patient, passed through the blood treatment unit (or dialyzer), and returned to the patient through the same or another vascular access device. At the same time, the liquid line draws the treatment liquid (ie, fresh dialysate) from the liquid source, passes the treatment liquid through the ...
