Device for preparing and/or treating a biological sample

摘要

The invention relates to a device for preparing and/or treating a biological sample including an assembly (2) of storage chambers (3) and/or reaction chambers intended for receiving a fluid and means arranged to move an amount of fluid from and/or to at least one of the chambers (3) of the assembly (2) of chambers (3), the chambers (3) being separated by walls (5) so as to form an assembly of adjacent chambers (3) aligned in a given direction. The means arranged to move an amount of fluid include a needle (6) connected to a transfer space (9), means (8) arranged to enable the suction of a liquid towards a chamber (3) from a transfer space (9) via a needle or delivery from the transfer space (9) to a chamber (3), and driving means (7) arranged to translate the needle (6) and the assembly (2) of chambers relative to one another in the chamber (3) alignment direction, and in that two adjacent chambers (3) are separated by a wall including a sealing membrane (5) or septum capable of being pierced by the needle (6) and of then recovering the seal thereof once the needle is removed. The invention also relates to a method for manufacturing such a device.

主权项

1. A device for preparing, treating, and/or analyzing a biological sample, comprising:
an assembly of storage chambers and/or reaction chambers intended for receiving a fluid, said chambers having shared walls so as to form an assembly of adjacent chambers aligned along a chamber alignment axis, said walls including a membrane or septum, said septum being able to be pierced by a needle, then recovering its seal once the needle is removed, the septum or septa constituting the wall(s) being located in a plane traversed by the chamber alignment axis, means for moving said fluid from and/or towards at least one of said chambers of the assembly, said movement means comprising:
a needle connected to a transfer compartment,suction/delivery means for said liquid connected to the needle upstream therefrom and separately from the volume of the chambers of the assembly, anddriving means arranged to translate the needle and the assembly of chambers relative to each other along the chamber alignment axis, such that the needle pierces the septum, and a chamber configured for storing, a reaction waste the chamber being disposed upstream from the transfer compartment and being in fluid connection with the transfer compartment.
