| 摘要 |
The invention concerns a pumping device (1) for transferring a fluid sample (2) into a sealed consumable (3), the transfer being performed between at least a first compartment, said to be initial, (4) and at least a second compartment, said to be, receiving, (5) via a narrowed section such as a flow path (6). The invention is characterised in that the point of intersection between an initial compartment (4) and the narrowed section is located in the lower part, and preferably at the lowest level, of said initial compartment (4), that the point of intersection between the receiving compartment (5) and said narrowed part is located in the upper part, and preferably at the highest level, of said receiving compartment (5), and at least one of the initial (4) and/or receiving (5) compartment can be deformed, such that each deformation activates the transfer of all or part of the sample (2), The invention is particularly applicable to microfluidic devices used in biology. |
