Abstract

A portable analyzer is disclosed. The analyzer comprises in combination a housing, an optical system comprising a light source, a detector, and one or more means for activating the optical system in generating a signal in response to a test element, means for manually moving the test element from a first position to a second position corresponding to a point of initiation of an operative condition of the optical system, means biasing the moving means toward said first position for controlling movement of the test element from the second position to the first position, means cooperative with said optical system, for processing the signal, and means, cooperative with the means for processing the signal, for displaying the processed signal.

Claims

1. An analyzer comprising in combination

a housing

an optical system comprising a light source, a detector, and one or more means for activating said optical system and generating a signal in response one or more test elements on a support,

means for manually moving said support from a first position to a second position corresponding to a point of initiation of an operative condition of said optical system,

means biasing said moving means toward said first position for controlling movement of said moving means from said second position to said first position to a point of termination of said operative condition of said optical system,

whereby a signal is generated for each test element during said operative condition,

means, cooperative with said optical system, for processing said signal, and

means, cooperative with said means for processing said signal, for displaying the processed signal.

2. The analyzer of claim 1 wherein said optical system is responsive to a test element which is part of an analyzing tool comprising one or more assay test elements and one or more reference test elements.

3. The analyzer of claim 1 wherein said optical system is responsive to a test element containing reagents of an immunochemical reaction.

4. The analyzer of claim 1 wherein said optical system is responsive to a test element containing reagents for producing a signal in relation to the amount of an analyte in a sample suspected of containing the analyte.

5. The analyzer of claim 1 wherein the means for manually moving the test element includes a holder for the test element.

6. The analyzer of claim 5 wherein the holder contains an aperture in a position corresponding to the position of the test element when the test element is placed in the holder.

7. The analyzer of claim 5 wherein the holder is separable from the analyzer.

8. The analyzer of claim 5 wherein said holder comprises a base for supporting said test element, a cover for said test element, and guide means for slidable movement of said holder in said analyzer.

9. The analyzer of claim 1 wherein said biasing means is a resilient material.

10. The analyzer of claim 1 wherein said biasing means is a spring.

11. The analyzer of claim 1 wherein said biasing means is a gas spring.

12. The analyzer of claim 1 wherein said biasing means includes a damper.

13. The analyzer of claim 1 wherein said means for processing said signal includes a microprocessor.

14. A portable analyzer comprising in combination

a housing

an optical system comprising a light source, a detector, and one or more means for activating said optical system and generating a signal in response to one or more test elements on a support,

a holder for said support comprising a base for supporting said support and a cover,

guide means incorporated into said housing for slidable movement of said holder within said analyzer, said holder being capable of manual movement in said analyzer from a first position to a second position corresponding to a point of initiation of an operative condition of said optical system by the interaction of said moving means and first switching means,

bias means for controlling the return of said holder from said second position to said first position to a point of termination of said operative condition of said optical system by interaction of said moving means and second switching means,

whereby a signal is generated for each test element during said operative condition,

means, cooperative with said optical system, for processing said signal, and

means, cooperative with said means for processing said signal, for displaying the processed signal.

15. The analyzer of claim 14 wherein the optical system is responsive to a test element which is part of an analyzing tool comprising one or more assay test elements and one or more reference test elements.

16. The analyzer of claim 14 wherein the optical system is responsive to a test element containing reagents of an immunochemical reaction.

17. The analyzer of claim 14 wherein the optical system is responsive to a test element containing reagents for producing a signal in relation to the amount of analyte in a sample suspected of containing the analyte.

18. The analyzer of claim 14 wherein said holder contains an aperture in a position corresponding to the position of the test element when the test element is placed in the holder.

19. The analyzer of claim 14 wherein the holder is separable from said analyzer and adapted for use with said analyzer.

20. The analyzer of claim 14 wherein said bias means is a resilient material.

21. The analyzer of claim 14 wherein said bias means is a spring.

22. The analyzer of claim 14 wherein said bias means is a gas spring.
