Abstract

The subject matter is a patient supporting device for supporting a patient during a medical treatment, in particular a dialysis treatment, and a treatment apparatus with such a patient supporting device, and a corresponding method for controlling and/or regulating a medical treatment device, in particular a dialysis device, using such a patient supporting device.

First claim

The invention claimed is:

1. Patient support comprising
a) an electricity conducting apparatus for carrying out a bioimpedance measurement on a patient's body,
wherein the apparatus comprises
a signal carrying device for coupling a measurement signal into the patient's body and
an electrically conductive device for coupling an electrical measurement value thereby generated in the patient's body out of the patient's body,

b) an apparatus for at least one of detection and calculation of hydrostatic pressure at least by inclination of one or more position adjustment parameters of the patient support selected from the group consisting of a back rest, leg rest, and foot rest, and
c) a data carrying interface for connecting to a medical treatment device,
wherein, when connected to the medical treatment device via the interface, data correlated with the electrical measurement value transmitted via the interface to the medical treatment device at least one of controls and regulates the medical treatment device.

2. Patient support according to claim 1 , characterized in that the medical treatment device is a dialysis device.

3. Patient support according to claim 1 , characterized in that the apparatus for carrying out a bioimpedance measurement further comprises a device for determining the patient's weight.

4. Patient support according to claim 1 , characterized in that the apparatus for carrying out a bioimpedance measurement further comprises at least two coupling-in electrodes, for contacting the patient's body for coupling the measurement signal into the patient's body by impressing a measurement current into the patient's body, and at least two coupling-out electrodes, for contacting the patient's body for coupling the electrical measurement value generated by the measurement signal in the patient's body out of the patient's body by capturing a change in potential generated by the measurement signal in the patient's body.

5. Patient support according to claim 4 , characterized in that at least one coupling-in electrode and at least one coupling-out electrode are for contacting each arm and each leg of the patient for carrying out a segmental bioimpedance measurement.

6. Patient support according to claim 1 , characterized in that the bioimpedance measurement is at least one of bioimpedance spectroscopy and bioimpedance vector analysis, with selective and specific detection of amplitude variation and phase displacement in the electrical measurement value.

7. Patient support according to claim 1 , characterized in that the bioimpedance measurement comprises at least one of a linear and a non-linear analysis of the electrical measurement value.

8. Patient support according to claim 2 , characterized in that, when connected to the medical treatment device, the electrical measurement value of the bioimpedance measurement in the patient's body is evaluated together with a blood analysis in an extracorporeal circulation of the dialysis device.

9. Patient support according to claim 1 further comprising a device for determining the patient's height containing at least one of pressure sensors and pressure sensor arrays disposed in the area of patient supporting surfaces of the patient support.

10. Patient support according to claim 1 further comprising an optical measurement device for three-dimensional detection of the patient's measurements.

11. Patient support according to claim 1 further comprising arm rests and a detecting apparatus for detecting positions of the arm rests.

12. Patient support according to claim 1 further comprising a motor-driven adjusting device for adjusting at least one of the back rest, leg rest, and foot rest.

13. Patient support according to claim 12 , characterized in that the motor-driven adjusting device is controlled by the medical treatment device.

14. Patient support according to claim 1 further comprising a device for determining the patient's identity.

15. Treatment apparatus comprising
a patient support according to claim 1 ,
the medical treatment device, and
a bioimpedance evaluation apparatus for evaluating the bioimpedance from the electrical measurement value that is coupled out by the electricity conducting apparatus for carrying out a bioimpedance measurement,
wherein the medical treatment device is at least one of controlled and regulated by the bioimpedance.

16. Patient support according to claim 1 further comprising a fingerprint sensor.
