Abstract

A method is provided for controlling a hand-held analysis device for analyzing a body fluid in which in each case at least one test means for single use is automatically provided in consecutive measuring cycles by means of a control device where each measuring cycle in a measuring mode of the control device is triggered by a start actuation. According to the invention it is proposed that a defined control intervention puts the control device into a maintenance mode in which the automatic provision of a test means is prevented.

Claims

1. A method for controlling a hand-held analysis device for analyzing a body fluid, the device comprising an electronic control device configured to automatically provide at least one test means for a single use in consecutive measuring cycles when the control device is in a measuring mode, each measuring cycle being triggered by a start actuation, the test means comprising a wound test tape, the method comprising the step of:

putting the control device into a maintenance mode by a defined control intervention, wherein the automatic provision of a test means is suspended during the maintenance mode so that the automatic provision of the test means in the hand-held analysis device is prevented.

2. The method according to claim 1, further wherein the start of a measuring cycle is blocked during the maintenance mode even in the case of a start actuation.

3. The method according to claim 1, wherein the device can be cleaned or test means can be exchanged in the maintenance mode without a loss of test means.

4. The method according to claim 1, wherein putting the control device into the maintenance mode is performed by selecting the maintenance mode via a software menu of the electronic control device.

5. The method according to claim 1, wherein putting the control device into the maintenance mode is performed by manually activating a switch comprising a softkey.

6. The method according to claim 1, wherein the start actuation comprises a predetermined operation of a component of the analysis device, said operation being recognized by the control device.

7. The method according to claim 1, wherein at least one of the start actuation and an exchange of test means is monitored by a sensor provided in the analysis device, wherein the sensor signal is ignored when the control device is put in the maintenance mode.

8. The method according to claim 1, wherein the test means are protected in a housing of the hand-held analysis device against environmental influences.

9. The method according to claim 1, wherein the start actuation for a measuring cycle comprises opening a protective cover of the hand-held analysis device whereupon a test means is provided for access by the user.

10. The method according to claim 1, wherein during the measuring mode the test means are automatically transported by a transport device to at least one predetermined position and the automatic transport of test means is suspended during the maintenance mode.

11. The method according to claim 1, wherein the respective test means are transported from a store of test means to an application site and transported to a test means waste during a measuring cycle.

12. The method according to claim 1, wherein a test tape furnished with a plurality of analytical test fields as test means is used and the test tape is wound up in sections in order to provide the test means.

13. The method according to claim 1, wherein the test means can be exchanged in a compartment of the device, the test means having the form of a magazine or a cassette, the test means being activated by a start actuation and discarded during the measuring mode when the compartment of the device is opened.

14. A hand-held analysis device for analyzing a body fluid, comprising an electronic control device for automatically providing test means designed for single use in consecutive measuring cycles where each measuring cycle can be triggered in a measuring mode of the control device by a start actuation and where a test tape is wound up in sections in order to provide the test means, wherein the control device can be put into a maintenance mode by a defined control intervention, in which maintenance mode the automatic tape transport is suspended, such that the automatic provision of a test means in the hand-held analysis device is prevented.
