Abstract

An armband comprising a detection device for detecting a blood count parameter in a blood vessel of the arm and an adjustment device for adjusting a predefined contact pressure of the armband on the arm.

Claims

1. An armband, comprising:

a detection device for detecting a blood picture parameter of blood in a blood vessel of the arm, and

a setting device for setting a predetermined contact pressure of the armband on the arm.

2. The armband as claimed in claim 1, wherein the setting device is configured to set a contact pressure of the armband to the predetermined contact pressure at least during detection of the blood picture parameter by the detection device.

3. The armband as claimed in claim 1, wherein the setting device comprises a sensor apparatus for measuring a current contact pressure of the armband on the arm and a control apparatus for setting the predetermined contact pressure depending on the measured current contact pressure.

4. The armband as claimed in claim 3, wherein the sensor apparatus is arranged on the an inner side of the armband.

5. The armband as claimed in claim 1, wherein the armband is configured as an inflatable armband.

6. The armband as claimed in claim 5, wherein the setting device comprises an air pump configured to inflate the armband to set the predetermined contact pressure.

7. The armband as claimed in claim 5, wherein the setting device comprises a sensor apparatus for measuring a current contact pressure of the armband on the arm, a control apparatus for providing a control signal depending on the measured current contact pressure, and an air pump, controlled by the provided control signal, for inflating the armband.

8. The armband as claimed in claim 1, wherein the detection device comprises configured to couple at least one radiofrequency signal into the blood vessel.

9. The armband as claimed in claim 8, wherein the setting device is configured to set the contact pressure of the electrodes on the arm to the predetermined contact pressure.

10. The armband as claimed in claim 1, wherein the setting device is configured to distribute the contact forces of the armband uniformly on the arm during detection of the blood picture parameter by the detection device.

11. The armband as claimed in claim 1, wherein the setting device is configured to provide uniform contact of the armband during detection of the blood picture parameter by the detection device.

12. The armband as claimed in claim 1, wherein the setting device is configured to keep the contact pressure of the armband constant during detection of the blood picture parameter by the detection device.

13. The armband as claimed in claim 1, further comprising a storage medium for providing the predetermined contact pressure.

14. The armband as claimed in claim 1, wherein the at least one blood picture parameter comprises a glucose concentration in the blood, a lactate concentration in the blood, a lactate concentration in the blood, or an oxygen concentration in the blood.

15. A method for operating an armband having a detection device for detecting a blood picture parameter of blood in a blood vessel in the arm, comprising setting a predetermined contact pressure of the armband on the arm.
