Embodiment Construction

[0061] In the following, the present disclosure will be explained in more detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate similar elements, and repeated descriptions of these elements may be omitted in order to avoid redundancy.

[0062] figure 1 is a schematic diagram of a system for treating a patient, in particular a device for dialysis. The system includes equipment for monitoring patient therapy.

[0063] specifically, figure 1 A dialyzer comprising a porous semi-permeable membrane 3 is shown. exist figure 1 On the right, the patient's blood circulation is connected to the membrane 3 and on the left, the dialysate circulation is connected to the membrane 3 . The principles of hemodialysis are well known and involve the diffusion of solutes in the blood through a semi-permeable membrane 3 . This diffusion is caused by the concentration gradient of certain substances on both sides of the membrane 3...

Abstract

The present invention pertains to a method for monitoring a treatment of a patient, preferably for monitoring hemodialysis, hemodiafiltration and / or peritoneal dialysis, the method comprising the steps of irradiating a sample of a dialysis liquid used in the treatment with irradiation light of at least a first irradiation wavelength, detecting light emitted by the irradiated sample in at least a first detection wavelength, the detection wavelength being different from the first irradiation wavelength, and determining the presence and / or concentration of at least one analyte in the sample on the basis of the detected light.

Description

technical field [0001] The present invention relates to a method and apparatus for monitoring the treatment of a patient, preferably for monitoring hemodialysis, hemodiafiltration and / or peritoneal dialysis. Background technique [0002] In vitro therapy has been used for a long time to treat different conditions. Dialysis is the most commonly known and used extracorporeal therapy for replacing the function of the kidneys in patients with renal failure of the kidneys. [0003] When kidneys fail, dialysis is necessary for the patient to remove waste products such as urea, creatinine, and uremic toxins from the patient's blood. Additionally, during dialysis, excess water and other substances that are normally excreted through urine are removed from the patient's body. The most commonly used method of dialysis is hemodialysis in which the patient's blood flows along a dialysis membrane, on the other side of which a dialysate is provided. Thus, blood and dialysate are separat...
