Abstract

A handheld medical device for body fluid analysis such as to measure an analyte concentration, for example glucose, in a body fluid such as blood or interstitial fluid by a patient or caregiver. The device comprises a mechanical assembly having a transport unit for consumable analytical elements, a display unit, a sensor for analyzing a body fluid sample obtained by a lancet prick, a memory for storing a series of measurement results, a first actuating element, the actuation of which transfers the device into a first active state, activates the mechanical assembly and prepares a measurement. In the first active state, a measurement is started by the actuation of one of the actuating elements, and a second actuating element, the actuation of which transfers the device into a second active state. The display unit is switched on by the actuation of the second actuating element, without activating the mechanical assembly.

Claims

1. A handheld analysis device, comprising:

a mechanical assembly, which comprises a transport unit for consumable analytical elements;

a display unit;

a sensor for analyzing a body fluid sample obtained by a lancet prick;

a memory for storing a series of measurement results;

a first actuating element, the actuation of which transfers the device into a first active state, activates the mechanical assembly and prepares a measurement, with the measurement being started in the first active state by actuating one of the actuating elements; and

,

a second actuating element, the actuation of which transfers the device into a second active state;

wherein the display unit is switched on by the actuation of the second actuating element, without activating the mechanical assembly.

2. The handheld analysis device as in claim 1 wherein the first actuating element is a cover for a device opening on which the body fluid sample is taken up.

3. The handheld analysis device as in claim 2 wherein the cover can be pivoted.

4. The handheld analysis device as in claim 2 wherein a third actuating element is provided for triggering a measurement, the third actuating element being disposed on a device opening and configured to be actuated by placing a body part on which a puncture wound is to be generated against the device opening.

5. The handheld analysis device as in claim 4 wherein a starting position, the first actuating element covers the third actuating element, and the first actuating element covers the device opening.

6. The handheld analysis device as in claim 1 wherein the mechanical assembly comprises a lancing drive so as to cause the lancets to perform a piercing movement.

7. The handheld analysis device as in claim 6 wherein a measurement is prepared by charging a mechanical energy storage means of the lancing drive.

8. The handheld analysis device as in claim 7 wherein a measurement is prepared by coupling the lancing drive to a lancet.

9. The handheld analysis device as in claim 1 wherein the consumable elements are test elements and/or lancets.

10. The handheld analysis device as in claim 1 wherein the mechanical assembly comprises an electric motor.

11. The handheld analysis device as in claim 1 wherein a measurement is prepared in that an consumable element is removed by the transport unit from an consumable element supply.

12. The handheld analysis device as in claim 1 wherein the display unit is switched on by actuating the first actuating element.

13. The handheld analysis device as in claim 1 wherein device settings can be modified in the second active state.

14. The handheld analysis device as in claim 1 wherein measurement results can be displayed by the display unit in the second active state.

15. The handheld analysis device as in claim 1 wherein it transitions from the second active state into an inactive state, in which the display unit is switched off.

16. The handheld analysis device as in claim 15 wherein it automatically transitions from the second active state into the inactive state when no actuating element was actuated during a predefined time period.

17. The handheld analysis device as in claim 1 wherein the mechanical assembly can be deactivated by actuating the first actuating element.

18. The handheld analysis device as in claim 1 further comprising, a magazine that can be inserted in the device, the magazine containing a consumable element supply.

19. A handheld analysis device, comprising:

a mechanical assembly, which comprises a transport unit for consumable analytical elements;

a display unit;

a sensor for analyzing a body fluid sample obtained by a lancet prick;

a memory for storing a series of measurement results;

a means for first actuating to transfer the device into a first active state, activates the mechanical assembly and prepares a measurement, with a measurement being started in the first active state by actuating one of the actuating elements; and

,

a means for second actuating to transfer the device into a second active state that switches on the display unit without activating the mechanical assembly.
