Abstract

The invention relates to a device for the collection, pre-analytic treatment, transport and grinding of solid samples, comprising a flask (1) having an opening (11) closed by a removable stopper (2), for receiving a solid sample. Said flask contains a pre-analytic medium (4), a plurality of balls (3) consisting of a solid material, and a means for holding the balls in place, that is designed to lose its effect when the flask is mechanically shaken or closed by the stopper, in such a way that, when the flask is mechanically shaken, the impact of the balls causes the grinding of the solid sample and the mixing thereof with the pre-analytic medium.

First claim

The invention claimed is:

1. A device for the collection, pre-analytical treatment, transport and grinding of solid samples, comprising a flask ( 1 ) having an opening ( 11 ) closed by a removable stopper ( 2 ), for receiving a solid sample and in which are present a pre-analytical medium ( 4 ) and a plurality of balls ( 3 ) made of a solid material, wherein the pre-analytical medium ( 4 ) comprises at least a first compound in gel holding the balls in place and being designed so as to liquefy and release the balls when the gel is disrupted, such that, when the flask is mechanically agitated, the impact of the balls causes the grinding of the solid sample and the mixing thereof with the pre-analytical medium, and wherein the first compound in gel holding the balls in place is located at the bottom of the flask.

2. The device as claimed in claim 1 , wherein the pre-analytical medium ( 4 ) comprises a second compound isolated from the rest of the flask by a means for holding in place designed so as to break and release the second compound when the flask is mechanically agitated or when the removable stopper is screwed or unscrewed.

3. The device as claimed in claim 2 , wherein the means for holding the second compound of the pre-analytical medium ( 4 ) is made of a tearable or breakable material.

4. The device as claimed in claim 3 , wherein the means for holding the second compound of the pre-analytical medium ( 4 ) comprises a seal closing the removable stopper ( 2 ) so as to provide a housing ( 24 ) for said second compound of the pre-analytical medium ( 4 ).

5. The device as claimed in claim 3 , wherein the means for holding the second compound of the pre-analytical medium ( 4 ) comprises a pouch ( 8 ) containing said second compound of the pre-analytical medium ( 4 ).

6. The device as claimed in claim 1 , further comprising a breakable pouch containing the first compound of the pre-analytical medium ( 4 ).
