Definitions
- the present invention relates to a method and an apparatus for transferring a fluid and more particularly a liquid, from a departure compartment to an arrival compartment, via a transfer channel, the transfer being effected under the action centrifugal force
- the state of the art consists of the document FR-A-2,678,379 relates to the transfer of a liquid into a device for sampling and restoring a predetermined quantity of liquid.
- This device is of tubular shape which contains in the vicinity of its periphery a blind helical channel which comprises the axis of centrifugation as axis of symmetry.
- the liquid rises in the device, while in the opposite direction, it leaves it.
- This device only allows the withdrawal and distribution of a withdrawn liquid. There is no possibility of orientation of the liquid internally.
- the versatility of this system is very limited, all the more so that for the sample to remain in the device, centrifugation must be maintained.
- centrifugation can be more versatile and therefore be integrated into an apparatus allowing multiple biological reactions to be carried out.
- many documents that are quite close to each other This is for example the case of patents US-A-3, 744,975, US-A-4,123,173 and US-A-4,225,558, which provide a device of flat and cylindrical shape, the center of which is occupied by an axis of rotation. This axis therefore makes it possible to transfer the liquids that this device contains from the center of said device to its periphery, under the action of centrifugal force.
- a method is proposed, the implementation of which is even more versatile, allows movements in all the compartments of the apparatus while avoiding the effects of a single centrifugation, and a distribution of the liquids in established proportions.
- the invention also relates to a method implementing such an apparatus.
- the present invention relates to a method for transferring a fluid from at least one starting compartment to at least one inlet compartment, via at least one transfer channel, the transfer taking place under the action of centrifugal force, the process consists of:
- the intermediate compartment is associated with at least two inlet compartments, each inlet compartment being connected to the intermediate compartment by a secondary transfer channel, and that it consists in carrying out at least a secondary centrifugation, allowing the orientation of the fluid present in said intermediate compartment towards the at least two inlet compartments.
- the invention also relates to an apparatus for transferring a fluid consisting of a body which comprises at least one outlet compartment, at least one inlet compartment and at least one transfer channel, this apparatus also comprises at least two axes centrifuge, a primary axis, to transfer the fluid from its starting compartment to an intermediate compartment, via a primary transfer channel, and at least one secondary axis, different from the primary axis, to transfer said fluid from the intermediate compartment to the inlet compartment, via a secondary transfer channel.
- each centrifugation axis cuts substantially perpendicularly an imaginary axis passing through the compartment, where the fluid is present, and through the compartment, where the fluid must be sent under the action of centrifugation according to the centrifugation axis concerned, and positioned between said compartment, where the fluid is present, and the edge of said device.
- each transfer channel between two compartments is substantially positioned along the imaginary axis passing through the two compartments, on either side of the channel concerned.
- each transfer channel between two compartments is associated with a centrifuge axis.
- each transfer channel is rectilinear and passes through the center of gravity of the two compartments, located on either side of said transfer channel concerned.
- each transfer channel comprises a blocking means, such as a ball valve, which prevents the passage of a fluid transferred or to be transferred.
- the intermediate compartment is associated with at least two adjacent inlet compartments, each inlet compartment being connected to the intermediate compartment by a secondary transfer channel, and these inlet compartments are associated with a single centrifuge axis which allows the distribution between the adjacent arrival compartments.
- the intermediate compartment comprises, at the level of the zones of intersection with the secondary transfer channels, which correspond to the adjacent arrival compartments, configurations which allow, under the action of centrifugation, the orientation of the starting fluid at said channels and an equitable distribution between said adjacent inlet compartments.
- Such an apparatus can be used for the analysis of one or more different liquid samples in which one seeks to identify one or more analytes, according to all the simple or complex analysis processes involving one or more different reagents depending on the chemical nature. , physical or biological of the analyte (s) sought.
- the technical principles defined below are not limited to a particular analyte, the only condition being that the analyte is distributed in the sample to be analyzed in suspension or in solution.
- the analysis process implemented can be carried out, in homogeneous or heterogeneous or mixed form.

- FIG. 1 represents an elevation view of a first embodiment of the present invention, before the first centrifugation.
- FIG. 2 represents an elevation view of a first embodiment of the present invention, after the first centrifugation and before the second centrifugation.
- FIG. 3 represents an elevation view of a first embodiment of the present invention, after the second centrifugation.
- Figure 4 shows an elevational view of a second embodiment of the present invention.
- Figure 5 shows an elevational view of a third embodiment of the present invention.
- the present invention relates to a new method for transferring a liquid 2 into a transfer device 1 consisting of a body 3.
- the device 1 has the shape of a parallelepiped even if sees only the upper face of this device or card 1.
- this card is obtained by machining a technical plastic material such as impact polystyrene reference R540E from the company GOODFELLOW, compatible with the treated liquids.
- the card could be obtained by precision molding, but all other manufacturing methods and in particular those used in semiconductor techniques such as those described in patent application WO-A-97/02357 are usable for the manufacture of said card.
- FIG. 1 to 3 a first embodiment is shown.
- the objective of this process is to allow the transfer of the sample 2, contained in a departure compartment 4, to four arrival compartments referenced 6.
- This device 1 therefore comprises a first departure compartment 4 located on the left of all of these figures. It is possible to pass through an intermediate compartment 5 which has a substantially “bean” shape, this intermediate compartment 5 being situated in the middle position, from the point of view of transit, between the departure compartment 4 and the arrival compartments 6 which are four in number in these figures.
- the compartments 6 are not positioned on the right of all the figures, this position being occupied by the intermediate compartment 5. The physical position of the compartments will be developed later in relation to the different stages of the transfer process.
- channels are present to allow transfer from compartment to compartment.
- FIGS. 1 to 3 there is a secondary transfer channel 10 for each inlet compartment 6, the channel 10, compartment 6 assembly being independent for each inlet compartment 6.
- the liquid sample 2 is present only at the level of the starting compartment 4. In this position, the liquid sample 2 is in fact in its initial position either because it has just been placed in place in this compartment 4, either because an independent transfer channel transported it to this compartment 4.
- a first centrifugation is carried out along Cl around the primary centrifugation axis 7.
- the liquid 2 will, according to the arrow FI, be transported in the intermediate compartment 5 via the primary transfer channel 9.
- the liquid 2 is in the position as far as possible from the axis 7 at the level of this intermediate compartment 5.
- a second centrifugation is carried out along C2 at the level of a secondary centrifugation axis 8.
- C2 the whole of the apparatus 1 is turned, according to C2, it is easy to understand that the liquid 2 will then be transferred to the inlet compartments 6 via the secondary transfer channels 10.
- F2 the liquid samples 2 which are distributed in the inlet compartments 6 are located in the farthest possible position relative to the centrifugation axis 8. So that the liquid sample 2, which is present in the intermediate compartment 5, does not return to the starting compartment 4, the shape of the compartment intermediate is quite specific at the point of implantation of the secondary transfer channels 10.
- the intermediate compartment 5 has a substantially "bean" shape of so that there are two lobes on one side of said compartment 5. These two lobes frame the point of intersection of the intermediate compartment 5 with the channel 9. Each lobe is associated with two channels 10, the shape of the compartment 5 then facilitating the orientation and transfer of the liquid during the second centrifugation along C2 towards the inlet compartments 6 by preventing, or at least minimizing, the passage of the liquid in the channel 9.
- a valve not shown in the figure, can be positioned on channel 9 to block the return of liquid if necessary.
- the volume of liquid contained in the lower lobe of the compartment 5 must be greater than the volume of liquid which it is desired to move in the two compartments 6 positioned below the channel 9 on the Figures 1 to 3.
- the volume of the lobe of compartment 5 is well defined on one side by a half-line perpendicular to channel 9 and positioned at the end of this channel 9 and on the other side by the intersection between the channels 10 and this same compartment 5.
- the same rule applies for the upper lobe.
- the volume of the lobe must also be less than the total volume of the two compartments 6 and of the two channels 10 associated with said compartments.
- the two lobes have the same volume.
- the two lobes have different volumes.
- the volumes of the inlet compartments are identical.
- the shape and dimensions of the channels 10 are chosen by a person skilled in the art to achieve a homogeneous distribution of the liquid in the different inlet compartments.
- the volumes of the inlet compartments are different
- the total volume of liquid transferable by this device can vary from 0.5 to 5000 microliters, advantageously from 2 to 2000 microliters and preferably from 5 to 1000 microliters.
- the volume of the starting compartment varies in the same proportions or can be significantly greater than the total volume to be transferred.
- the compartment in the embodiment of FIGS. 1 to 3, the compartment
- a starting compartment 14 present in the center of the body 13, this compartment 14 being connected via four primary transfer channels 19 to four intermediate compartments 15.
- the four intermediate compartments are located symmetrically with respect to each other.
- each centrifugation axis 17, 18 or 12 is placed on this straight half in a position located between the intermediate compartment 15 and the edge of the card or transfer device 11.
- inlet compartments 16 which are connected to the intermediate compartment 15 by secondary transfer channels 20. It is immediately noted that these secondary transfer channels 20 have a point of intersection with the intermediate compartment 15, by which one can pass a straight line passing through the center of gravity of the intermediate compartment 15. This straight line is in fact substantially perpendicular with respect to the half-line going from the center of gravity of the starting compartment 14 to the center of gravity of the intermediate compartment 15.
- each inlet compartment 26 is associated with two terminal transfer channels 32 which connects it to two terminal compartments 31.
- valves are well described in the patent application filed by the applicant on September 9, 1998 under the number FR98 / 11383, and entitled “Device allowing reactions, transfer system between devices and method of implementing such a system " Likewise, and although this does not appear in FIGS. 1 to 4, fluid inlets and / or outlets are fitted to the apparatus described in the present invention in order to ensure its correct operation.
- centrifugations In order for centrifugations to be effective, they need not be too rapid. A centrifugation of between 2 and 10 g (symbol of the acceleration of gravity), and preferably between 3 and 5 g, is quite sufficient for non-viscous biological liquids. For viscous liquids, a force between 10 and 200 g is applicable.
- centrifuge axes As many centrifuge axes as there are transfer channels between two adjacent compartments between which it is desired to transfer a liquid. So on Figures 4 and 5, there are only four axes 27, 28 and 22. It would also be possible to consider them at the angles of each device 11 or 21, in order to facilitate transfer to the arrival compartments 16 or 26, or even towards the terminal compartments 31. In addition, and always to improve the efficiency of these centrifugations, these channels are preferably rectilinear.
