Embodiment Construction

[0043] figure 1 with figure 2 An exemplary embodiment of a test card 1 comprising a plurality of sample wells 2 isolated from each other is shown. Before describing the sealing properties of the well 2, it should be recalled that the test card 1 used for analysis generally presents a plate or support 3 with a small thickness, which has a so-called first front main face 4 and an opposite so-called The second rear main face 5. In the example shown, the plate 3 is rectangular and has two longitudinal sides 31 parallel to each other and connected by two transverse sides 32 also parallel to each other.

[0044] The test card 1 comprises at least one well 2, and in the example shown a plurality of wells 2, which in a preferred embodiment are arranged in rows and columns. In the example shown, wells 2 distributed in eight rows and columns are open on both faces 4 and 5 . Of course, the number, geometry and arrangement of wells 2 can be realized in different ways. Traditionally,...

Abstract

The invention relates to a method for isolating at least one fluid-sample well provided in a test card for analysis, said test card comprising a plate (3) having at least one first main surface from which at least one channel, in communication with at least said well, extends, said first surface being covered by a membrane (17) provided with an adhesive (18) and covering said channel with a covering area (17i). The isolation method comprises a step of feeding a fluid sample into at least said well, and a step of isolating said well involving exerting force onto at least a portion of the covering area (17i) of the adhesive membrane (17) so as to ensure the movement of the adhesive within a sealing area for the sample well.

Description

technical field [0001] The present invention generally relates to the technical field of a device and machine for testing biological samples, and in particular to a test card (test card, test card) for analysis, in which a plurality of channels are arranged for Supplies fluids and is well suited for receiving reagents and fluids or test samples containing microbial agents such as microorganisms. [0002] More specifically, the present invention aims at a technique that offers the possibility of ensuring the obturation of these wells in order to avoid any risk of contamination between these different wells. Background technique [0003] In the prior art, numerous publications describe various test cards for analysis having wells or reaction chambers designed to receive reagents and fluid samples containing microbial agents, such as microorganisms. Such a test card, such as that described by patent EP0908728, comprises a plate in which a plurality of wells are arranged which ...
