Abstract

In a first aspect, the present invention provides a handgrip configured to extract an analysis strip from a groove of an analyser. The handgrip comprises a casing piece configured to be attached with the analyser, and a retaining piece having a retaining portion. The retaining piece is movable with respect to the casing piece in such a way that the retaining portion is movable in a first direction from a proximal position to a distal position relative to the casing piece. The retaining portion is configured to retain the analysis strip during at least part of its movement from the proximal to the distal position, and to avoid retaining the analysis strip at least when the retaining portion is in any of the proximal and distal positions.

First claim

The invention claimed is:

1. A handgrip configured to extract an analysis strip from a groove of an analyser, the handgrip comprising:
a casing piece configured to be attached with the analyser; and
a retaining piece having a retaining portion, the retaining piece being movable with respect to the casing piece in such a way that the retaining portion is movable in a first direction from a proximal position to a distal position relative to the casing piece;
wherein:
the retaining portion is configured to retain the analysis strip during at least part of its movement from the proximal to the distal position, and to avoid retaining the analysis strip at least when the retaining portion is in any of the proximal and distal positions.

2. A handgrip according to claim 1 , wherein:
the retaining portion comprises a pressing arrangement;
the pressing arrangement is configured to exert pressure to the analysis strip, thereby causing the retention of the analysis strip, during the at least part of the movement of the retaining portion from the proximal to the distal position; and
the pressing arrangement is configured to avoid exerting pressure to the analysis strip, thereby causing the avoidance of retention of the analysis strip, at least when the retaining portion is in any of the proximal and distal positions.

3. A handgrip according to claim 2 , wherein:
the pressing arrangement comprises a first and a second pressing member facing each other and defining a path having a distance between them, said path being perpendicular to the first direction;
the first and second pressing members are configured to reduce the distance between them, thereby causing the exertion of pressure to the analysis strip, during the at least part of the movement of the retaining portion from the proximal to the distal position; and
the first and second pressing members are configured to increase the distance between them, thereby causing the avoidance of exertion of pressure to the analysis strip, at least when the retaining portion is in any of the proximal and distal positions.

4. A handgrip according to claim 3 , wherein the first and second pressing members are arranged in such a way that the distance reduction causes the exertion of pressure to the analysis strip at corresponding first and second lateral regions of the analysis strip, during the at least part of the movement of the retaining portion from the proximal to the distal position.

5. A handgrip according to claim 3 , wherein at least one of the first and second pressing members is a flexible member configured to be flexed to a compressed position for causing the distance reduction during the at least part of the movement of the retaining portion from the proximal to the distal position, and to be flexed to a relaxed position for causing the distance increase at least when the retaining portion is in any of the proximal and distal positions.

6. A handgrip according to claim 5 , wherein both the first and second pressing members are flexible members configured to be flexed to the compressed position for causing the distance reduction during the at least part of the movement of the retaining portion from the proximal to the distal position, and to be flexed to the relaxed position for causing the distance increase at least when the retaining portion is in any of the proximal and distal positions.

7. A handgrip according to claim 5 , wherein the casing piece comprises a guiding piece for each flexible pressing member respectively, each guiding piece being configured to guide its corresponding flexible pressing member to the compressed position for causing the distance reduction during the at least part of the movement of the retaining portion from the proximal to the distal position, and to guide its corresponding flexible pressing member to the relaxed position for causing the distance increase at least when the retaining portion is in any of the proximal and distal positions.

8. A handgrip according to claim 1 , wherein the casing piece is configured to be removably attached with the analyser in a press-fitting manner.

9. A handgrip according to claim 8 , wherein the casing piece comprises at least two flanges configured to press against corresponding end sides of the analyser respectively, in such a way that the analyser can be press-fitted within the casing piece.

10. A handgrip according to claim 9 , wherein the casing piece comprises a sheet-shaped portion connecting the at least two flanges and being configured to at least partially cover a rear/bottom side of the analyser when the analyser is press-fitted within the casing piece.

11. A handgrip according to claim 10 , wherein the retaining piece comprises a sheet-shaped portion slidably coupled to the sheet-shaped portion of the casing piece.

12. A handgrip according to claim 11 , further comprising a rail based mechanism; wherein the sheet-shaped portion of the retaining piece is slidably coupled with the sheet-shaped portion of the casing piece by said rail based mechanism.

13. A handgrip according to claim 11 , wherein the sheet-shaped portion of the retaining piece has an external rough surface.

14. An analyser comprising:
a groove for inserting an analysis strip; and
a handgrip configured to extract the analysis strip from the groove, according to claim 1 .

15. An analyser according to claim 14 , further comprising the analysis strip inserted in the groove.
