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 a tape drive unit for advancing test fields, an electronic control device configured to automatically provide at least one test field on a test means comprising a plurality of test fields for single use arranged on a wound test tape in consecutive measuring cycles when the electronic control device is in a measuring mode, each measuring cycle being triggered by a start actuation, and a sensor for monitoring and outputting a signal responsive to the start actuation, the method comprising the step of:

putting the electronic control device into a maintenance mode by a defined control intervention, wherein the sensor signal is ignored when the electronic control device is put in the maintenance mode, thereby suspending the automatic provision of at least one of the plurality of test fields on the test means inserted into the hand-held analysis device during the maintenance mode, and wherein the defined control intervention is manually activating a switch comprising a softkey or control button of the hand-held analysis device to thereby put the electronic control device of the hand-held analysis device into the maintenance mode.

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 electronic 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 the start actuation comprises a predetermined operation of a component of the analysis device, the operation being recognized by the electronic control device.

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

7. 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.

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

9. The method according to claim 1, wherein the 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.

10. 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 to provide the test means.

11. 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.

12. A hand-held analysis device for analyzing a body fluid, the device comprising:

a device housing;

a tape drive unit for advancing test fields on a test means comprising a plurality of test fields for single use arranged on a wound test tape;

a measuring unit for obtaining measurement results from the test fields;

an electronic control device for automatically providing at least one test field on the wound test tape in consecutive measuring cycles where each measuring cycle can be triggered in a measuring mode of the electronic control device by a start actuation and where the test tape is wound up in sections to provide the at least one test field on the test means; and

a sensor for monitoring and outputting a signal responsive to the start actuation;

wherein the electronic control device can be put into a maintenance mode by a defined control intervention when the wound test tape is present in the hand-held device, wherein the sensor signal is ignored when the electronic control device is put into the maintenance mode, thereby suspending the automatic provision of the at least one test field on the wound test tape, and wherein the defined control intervention is manually activating a switch comprising a softkey or control button of the hand-held analysis device.
