Abstract

Electrodes for a bio-impedance measuring device or a body composition monitor, the electrodes being integral with or being attached to a surface of at least one device belonging to a group of electronic and/or non-electronic devices used in the preparation of a dialysis treatment or during dialysis, in particular during peritoneal dialysis, the group preferably consisting of organizers of a continuous ambulatory peritoneal dialysis system (CAPD), automated peritoneal dialysis devices, automated peritoneal dialysis-cyclers (APD-Cycler), bioelectrical impedance analyzers (BIA), body composition monitors (BCM), hand-held electrodes holders for the electrodes, and dialysis apparatuses. Devices and methods used during dialysis are also described.

Claims

four electrodes, each electrode being integral with a surface of (i) an organizer of a continuous ambulatory peritoneal dialysis system (CAPD), (ii) an automated peritoneal dialysis device, or (iii) an automated peritoneal dialysis-cycler (APD-Cycler),

wherein the device is configured to start measuring or to allow measuring the bio-impedance or the body composition, or both, upon or by inserting a disc with a dial into the device, wherein the dial is rotatable relative to the disc for selecting between two or more operating states of the device.

2. The device of claim 1, wherein each electrode is a reusable electrode.

3. The device of claim 1, wherein the four electrodes includes a first electrode and a second electrode, the first and second electrodes spaced apart from each other at a distance of 2.5 to 15 cm.

4. The device of claim 3, wherein the first and second electrodes are spaced apart from each other at a distance of 4 to 7.5 cm.

5. The device of claim 3, wherein the first and second electrodes are arranged on different housing surfaces of the CAPD, the peritoneal dialysis device, or the APD-Cycler.

6. The device of claim 1, wherein the CAPD, the peritoneal dialysis device, or the APD-Cycler has at least one connection element configured to connect the CAPD, the peritoneal dialysis device, or the APD-Cycler to at least one of a (a) bio-impedance device or (b) body composition monitor.

7. A system for determination of a bio-impedance or a body composition of a patient in preparation of, or during, a peritoneal dialysis treatment, comprising:

a device comprising;

four electrodes, each electrode being integral with a surface of (i) an organizer of a continuous ambulatory peritoneal dialysis system (CAPD), (ii) an automated peritoneal dialysis device, or (iii) an automated peritoneal dialysis-cycler (APD-Cycler); and

at least one of a (a) bio-impedance device and a (b) body composition monitor,

wherein the at least one of the (a) bio-impedance device and the (b) body composition monitor is connected to the CAPD, the peritoneal dialysis device, or the APD-Cycler of the device, and

wherein the device is configured to start measuring or to allow measuring the bio-impedance or the body composition, or both, upon or by inserting a disc with a dial into the device, wherein the dial is rotatable relative to the disc for selecting between two or more operating states of the device.

8. The system of claim 7, wherein the system is configured to measure the bioelectrical impedance or the body composition, or both, upon touching of the four electrodes while the disc with the dial is inserted the device.

9. The system of claim 7, further comprising:

a device configured to send measurement data to at least one of (i) a dialysis apparatus, (ii) a medical monitoring center, or (iii) a medical card of the patient.

10. A dialysis apparatus in signal communication with the system of claim 7 and configured to receive measurement results from the four electrodes.

11. The dialysis apparatus of claim 10, comprising:

a control unit, the control unit configured to control the peritoneal dialysis treatment based on the measurement results from the four electrodes.
