- the present invention relates to four positioning devices which make it possible to achieve precise positioning of a liquid sample 2 as will be well explained in relation to the attached figures.
- the first embodiment is shown in Figure 1. It relates to a positioning device 1 according to an embodiment which essentially consists of a channel of constant diameter over its entire length. This channel in fact comprises three very functionally different zones at the level of the positioning device 1.
- This container 5 has a curved shape. Finally, there is an exit 4, present in the extension of the inlet 3 and of the container 5, which allows the possible evacuation of this sample 2.
- the channel also comprises, in a substantially parallel position, a branch 6 which connects the inlet 3 to the outlet 4.
- this branch has a cross section and a diameter which are substantially smaller than the cross section and to the diameter of the channel comprising the inlet 3, outlet 4 and container 5. This difference in diameter ranges from double to fivefold.
- the choice of the shape and the section of the different channels can also vary depending on the nature of the liquids to be transferred.
- wetting liquid such as for example an aqueous solution containing Triton XI 00 (registered trademark) or Tween (registered trademark) in a proportion of 0.5 to 2 ml / 1
- Triton XI 00 registered trademark
- Tween registered trademark
- FIG. 2 there is shown a second embodiment 11 in which two differences are present compared to the first embodiment of Figure 1.
- the channel is absolutely straight, that is to say that the inlet 13, the container 15 and the outlet 14 are located in the extension of each other.
- this embodiment is not compulsory and it is quite possible to use a container 5 of curved shape as shown in FIG. 1.
- the point of intersection between the inlet 13 and the bypass 16 includes a means 18 which makes it possible to break the bubbles which can be generated by the liquid sample 2 when the latter is in transfer in the main pipeline
- the third embodiment is shown in these Figures 5 to 8. It is a device 21 which incorporates the most relevant characteristics of the first two embodiments. Thus, there is an inlet 23, an outlet 24 and a container 25, the container 25 having a curved shape in the same way as in the first embodiment with the container 5.
- the branch 26 always connects the inlet 23 and the outlet 24, however, like the embodiment of Figure 2, a means for breaking the bubbles 28 is present between the inlet 23 and the bypass 26. In this Figure 5, no liquid sample 2 is represented.
- FIG 11 a sectional view along C-C of Figure 5, there is a particular arrangement of the channels at the intersection between the inlet 23 and the bypass 26 when a means 28 for breaking bubbles is present.
- the depth of the channels is such that a setback exists between 23 and 28 and another setback is present between 28 and 26.
- the setback between 23 and 28 generates a sharp edge which improves the efficiency of the means 28 for breaking bubbles.
- a sharp edge between 26 and 28 is present.
- 2 millimeters (mm) for a width of 2 mm can be chosen for the channel 23, a depth of 1.5 mm on a width of 3 mm for the medium 28, and a depth of 0.5 mm with a width of 0 , 5 mm for the bypass 26.
- the liquid fills the cavity 25 then the movement is stopped.
- the volume of liquid to be isolated must be less than the volume of the container 25.
- FIGS. 6 to 8 it is easier to understand the operating mode of this device 21, an operating mode which is identical for the first two embodiments.
- the liquid 2 arrives at the level of the inlet 23 and said liquid 2, under the action of an external pressure P shown on the Figure 7, will flow into the container 25. It is preferable to use gravity to allow such a movement according to FI.
- the dimensions of the bypass 26 and the channel formed by the inlet 23, outlet 24 and container 25 can be calculated in order to allow the liquid 2 to spontaneously orient itself towards the container 25 under the action of the pressure P.
- the liquid sample 2 is exclusively included in the container 25, this sample 2 being bounded by the inlet 23 and the outlet 24.
- the pressure P is still present, nevertheless, the thrust no longer exerts on the liquid but on the bypass according to the arrows F2. Therefore, the liquid sample 2 is well positioned at the predetermined location. It is therefore also possible to provide at the level of the container 25, another channel called the outlet channel 53, which allows, depending on the opening or closing of a valve, not shown in the figures, the transfer of the volume sample. determined 2 from this predetermined position to a container allowing a biological reaction, for example, amplification of nucleic acids or a reaction between antigens and antibodies, etc.
- valves 51 allowing, depending on the opening or closing, transfer of the liquid samples 2, from a container 15 to another container 15 or to the outlet 55.
- valves 51 allowing, depending on the opening or closing, transfer of the liquid samples 2, from a container 15 to another container 15 or to the outlet 55.
- the presence of these valves is not compulsory.
- valves make it possible to limit the phenomena of evaporation which can lead to a modification of the volume in the compartment inducing an uncontrolled heating of the reagents or a problem of contamination in another compartment.
- valves including on the branches.
- FIG. 4 a sectional view, along A- A of FIG. 3, shows that the two containers 15 located in the extension of one another can be positioned on different faces of the card 40.
- the first container 15, located on the left is open on its upper face
- the second container 15, located on the right is open on its lower face.
- these films are referenced 56 on one side as on the other of said card 40.
- the nature of the flexible film may vary depending on the nature of the analysis card and of the fluids tested, in particular for compatibility reasons.
- a TPX (polymethylethylpentene) or BOPP (bi-oriented polypropylene) polymer film makes it possible to carry out biological tests.
- the fixing of these films can be carried out by gluing (coating of glue such as for example silicone glues on the film) or by welding.
- An example of adhesive BOPP is provided by the company BioMérieux Inc (St Louis, MO, USA) under the reference 022004-2184.
- the analysis 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 the analysis card.
- each card 40 it is therefore possible to have several positioning devices 1, 11 or 21 positioned in series, one behind the other. It is also possible to have a certain number of reaction chains 50 constituted by several devices in series mounted in parallel, this is clearly visible in this figure 3. According to an alternative embodiment, it is also possible to mix the different embodiments of positioning devices as shown above. Finally, it is also possible to vary the volume of each container 5, 15 or 25 in order to adapt the volumes transferred as a function of the reactions which it is necessary to carry out subsequently.
- the sample which one wishes to isolate in order to be able to move it subsequently, must be of a large volume, a container volume corresponding to the first and third embodiment is used, whereas a lower volume , with identical pipe section, it will be necessary to use the second embodiment of FIG. 2.
- the volume of the sample 2 can also be varied by varying the length and / or the diameter of the container 5, 15 or 25. All the alternatives envisaged above can also take into account the device 31 according to the fourth embodiment.
- This fourth embodiment is well represented in FIGS. 9 to 11.
- FIG. 9 there is a reaction chain 52 substantially identical to one of the reaction chains 50 shown in FIGS. 3 and 4.
- One of the devices 31, which constitute this reaction chain, is better represented in FIG. 10.
- the volume of the container 35 which is not constituted by a pipe, as was the case previously, but by a compartment whose volume is clearly greater.
- This embodiment is more suitable with a card positioned substantially vertically, so that gravity makes it easier to fill the container.
- branch 36 and 37 made up of two dissimilar parts.
- the first part 36 has a point of intersection with respect to the inlet 33 while the second part 37 has a point of intersection with the outlet 34.
- the two parts of the bypass 36 and 37 are connect to each other at a point of intersection from which a discharge pipe 57 from the surplus of the liquid sample 2 starts.
- this pipe 57 is of a identical diameter to and is located in the extension of the first part of the branch 36.
- the volume of the sample to be distributed is equal to the total volume of the compartim ents 35. In another embodiment, the volume of the sample to be distributed is greater than the total volume of the compartments 35.
- the purging of the upper lines 36 and 57 can be carried out by applying a variation pressure or other means or else a compartment 35 can be provided which acts as a receiving compartment for the surplus liquid and situated at the end of the reaction chain 52.
- the first three embodiments are used instead.
- the fourth embodiment is used instead. This case occurs for example in the case of multiple analysis for the same sample as the simultaneous determination of several pathogens both in immunoassays and in the diagnosis by nucleic probes. It is possible to use this device to isolate volumes of liquid between 1 and 5000 microliters, advantageously between 5 and 2000 microliters and preferably between 10 and 1000 microliters.
- inlet 33 extends at the level of the container 35 in a particular form well represented in the sectional view B-B of FIG. 11.
- the entry 33 is of quite normal size.
- this inlet 33 there is a means 39 for draining the liquid sample 2 in order to orient it and facilitate its transfer to said container 35.
- This means 39 consists of a bevel shape, the spacing with respect to the outer film 56, which partitions the device 31, is appreciably greater at the level of the container 35 than at the level of the inlet 33. This fairly small distance between the means 39 and the film 56 facilitates the orientation of the liquid sample 2 by simple capillarity.
- Card comprising several chain 50 in parallel 50.
- Reaction chain comprising several devices 1 1 in series
