Abstract

The invention relates to a rapid diagnosis device with a device housing, on which there is provided a push-in opening for a test strip. The test strip is evaluated inside the rapid diagnosis device. On the device housing there is formed a housing opening, which can be closed by a cover or flap element. The cover or flap element is assigned a locking body. The locking body is formed as a spring element which comprises a clip portion, which assumes a position locking the spring element when the test strip has been pushed into the push-in opening of the rapid diagnosis device.

Claims

1. A rapid diagnosis device comprising a device housing, wherein the device housing comprises a push-in opening for a test strip and a housing opening, and wherein

the test strip is evaluated inside the rapid diagnosis device, and

the housing opening can be closed by a cover or flap element, wherein

the cover or flap element is assigned a locking body,

the locking body is configured as a spring element which comprises a clip portion, and

the clip portion is configured to lock the spring element when the test strip is pushed into the push-in opening.

2. The rapid diagnosis device of claim 1, wherein the clip portion is formed on a spring tongue of the locking body which is resiliently arranged between spring legs.

3. The rapid diagnosis device of claim 2, wherein the spring tongue is formed with a crank.

4. The rapid diagnosis device of claim 2, wherein bearing webs run on the side of the spring tongue facing towards the test strip.

5. The rapid diagnosis device of claim 2, wherein stops lying opposite side faces of the clip portion are formed on the spring legs of the spring element.

6. The rapid diagnosis device of claim 5, wherein the clip portion is placed between the stops when the test strip is inserted into the locking body and blocks their deflection in the lateral direction.

7. The rapid diagnosis device of claim 5, wherein in a second clip portion position, without the test strip, the clip portion permits a deflection of the stops and the cover or flap element can be unlocked.

8. The rapid diagnosis device of claim 2, wherein pegs which can be inserted into clip-in locations on the cover or flap element are arranged on the spring legs.

9. The rapid diagnosis device of claim 5, wherein the stops on the spring legs are formed with a projection.

10. The rapid diagnosis device of claim 5, wherein the pegs are positioned offset with respect to one another on the spring legs.

11. The rapid diagnosis device of claim 8, wherein the stops are positioned offset with respect to one another on the spring legs.

12. The rapid diagnosis device of claim 1, wherein the locking body is arranged in the cover or flap element.

13. The rapid diagnosis device of claim 1, wherein the locking body is accommodated in the device housing.
