Definitions
- the invention relates to a microfluidic storage device comprising at least one reservoir chamber formed by bulging a film or membrane for a fluid, a predetermined breaking point for forming an opening of the storage device and a transport path leading from the storage chamber to an opening of the storage device e.g. at an interface between the storage device and a microfluidic processing device.
- Such a storage device is used in addition to the storage of the transport and / or the targeted release of fluids.
- the processing device may e.g. be used for the analysis of fluids (gases and liquids) in medical diagnostics and analytics as well as environmental analysis.
- a memory device of the kind mentioned in the opening paragraph is known from WO / 002007002480A2.
- the predetermined breaking point breaks and the fluid can flow through a channel forming the transport path to the said opening.
- a controlled dosage is impossible.
- air bubbles form in the transport path when the fluid emerges in an abrupt manner because the air present in the transport channel can not be completely displaced.
- the uncontrolled entrainment of the air bubbles significantly impairs the function of the fluid during further processing in the fluidic processing device.
- the invention has for its object to provide a new microfluidic storage device of the type mentioned above, which allows a more accurate dosage of fluid quantities removable from it and in particular avoids the formation of air bubbles. Furthermore, further uses of the transport route are to be developed.
- the storage device according to the invention which achieves this object is characterized in that the transport path can be opened to a transport channel in accordance with the fluid flow emerging from the storage chamber.
- the transport path itself has virtually no volume when the storage chamber is closed. The widening to a channel takes place, preferably by the pressurized fluid itself only with the removal of the fluid from the reservoir.
- the fluid e.g. a reagent to be processed in a flow cell, metered and free of bubbles remove from the storage device and the transport distance beyond, for example, to use as a valve.
- the predetermined breaking point is arranged directly on the storage chamber and the transport path leads from the predetermined breaking point to the opening at the said interface.
- the predetermined breaking point could be formed by the transport path itself, as explained below.
- the transport path to abutting or applyable channel walls of which at least one wall is deformable by the fluid to form the transport channel.
- the wall may be stretchable by the fluid for forming the transport channel.
- the channel walls are each formed by a flexible film or membrane or by a flexible film and a rigid plate.
- the said films or the film and the plate are not or weakly connected in the region of the transport path than in the adjacent areas.
- the latter compound may be so weak that it breaks under the pressure of the fluid. In this way, the transport route itself can serve as a predetermined breaking point.
- the storage device according to the invention may be integrated in said microfluidic processing device.
- the transport route may include several sections between which e.g. a container is arranged to comprise.
- This may be a measuring container or a container containing a reagent, in particular a dry reagent.
- the transport paths of several storage containers have a common, e.g. from a mixing chamber to said opening at the interface leading portion.
- the transport path may have a plurality of sections connected in parallel or in series, which may be e.g. from a distribution chamber to several openings at the interface.

- FIG. 1 1 - 14 further embodiments of memory devices according to the invention in a plan view
- 15 shows a storage device according to the invention with a transport path, which has a plurality of intermediate containers, in a side view
- FIG. 16 shows a further exemplary embodiment of a memory device according to the invention
- FIG. 18 shows an exemplary embodiment of a storage chamber of a storage device according to the invention.
- a storage device for storing a fluid 1 shown in Fig. 1 is provided with a fluid 1, e.g. as a reagent-processing flow cell 2, which has a base plate 3 and a lower cover 4, connected.
- the storage device comprises a storage chamber 5 for the fluid 1, which is formed by a deep-drawn bulge 6 in a film 7 and a bulge 6 covering, associated with the film 7 film 8.
- the films 7 and 8 are connected to each other, except for the region of the storage chamber 5 and the region of a transport path 9 over its entire surface, e.g. welded or glued. In the region of the transport path 9 lie, as can be seen in particular from FIG. 3, the films 7 and 8 only to each other.
- a narrow welding or adhesive area, which forms a predetermined breaking point 10 separates the interior of the storage chamber 5 from the transport path 9. Deviating from the embodiment described here, the films 7 and 8 outside the storage chamber and the transport path need not be connected to each other over their entire surface , It suffices a the supply chamber and the transport path limiting connection area, which withstands the pressurization more than the predetermined breaking point 10.
- the transport path 9 leads to a passage opening 1 1 in the film 8, which is preferably congruent to a passage opening 26 in the base plate 3. From the predetermined breaking point 10, the width of the transport path decreases continuously up to the passage opening 1 1.
- the storage device is bonded to the base plate 3 via the film 8.
- the passage opening 26 in the base plate 3 leads to a channel 13 in the flow cell 2, which ends, for example, at a fluid chamber 1 receiving reaction chamber (not shown).
- a fluid chamber 1 receiving reaction chamber (not shown).
- the previously hermetically sealed storage chamber 5 is compressed according to arrow 14 (FIG. 4), the break-off point 10 breaking under the pressure of the fluid 1.
- the pressurized fluid 1 opens up a transport channel 15 by deforming the film 7 under stretching in the region of the transport path 9, as shown in FIG. 5.
- the fluid 1 finally passes through the passage openings 11 and 26 into the channel 13 covered by the film 4 in the flow cell 2.
- the storage device described above also allows a very accurate dosage of individual, expressed from the storage chamber 5 subsets of fluid stored therein 1. If the pressure is withdrawn as indicated by arrow 14, then closes due to elastic restoring force of the film 7, the transport path and transferred into the flow cell Fluid flow comes to a halt.
- the fluid flow could be interrupted by acting on the transport path 9 according to arrow 16 blocking element, in the simplest case in the form of a punch, and the transport path together with the films 7 and 8 against each other oppressive blocking element can be used as a valve, the removal of desired subsets allows the stored fluid supply.
- the blocking element acts according to arrow 16 as a proportional valve.
- the pressurized valve can form the cross-section of the transport path differently far, whereby the flow rate of the fluid can be controlled.
- the valve function regardless of the strength and rigidity of the base plate, which otherwise to the blocking element Counter-contact forms, with the help of a second, from the opposite direction vorschiebbaren blocking element can be performed even more efficient.
- the film 8 could be omitted and the film 7 are connected directly to the base plate 3, so that the bulge 6 and the transport path 9 are limited on one side directly by the base plate 3.
- Fig. 6 shows an embodiment of a transport path 9a, which is formed by a film 7a and a film 8a, the films outside the transport distances 9a, as in the embodiment of FIG. 1 to 5, glued together or welded , Notwithstanding this embodiment, both films have room for deformation, in particular under elongation, so that they can form a transport channel 15a with both sides curved walls. Depending on the stiffness of the films 7a and 8a, a symmetrical or asymmetrical curvature may result.
- a storage chamber 5b could be formed by two films 7b and 8b, each with a bulge 6b or 6b '.
- the bulges may vary in shape and dimensions depending on the thermoforming tools used in cold or hot deep drawing.
- the shape of the storage chamber may differ from the chamber shown in Figs. 1-5 and not round, but e.g. be elongated.
- the flow cell has a stepped base plate 3c and a cover plate 17.
- the storage device is integrated between the cover plate 17 and a resting on the base plate 3c layer 18 made of an elastomeric material.
- an elastic membrane 19 forms a storage device.
- the elastic membrane consists for example of a thermoplastic elastic elastomer and / or silicone material.
- a transport path 9d, is bounded by the membrane 19 and a base plate 3d of the flow cell.
- the exemplary embodiment of FIG. 10 differs from the preceding exemplary embodiments in that no through opening 26d that passes through the base plate is formed, but that a channel 13e directly adjoins a transport path 9e.
- 1 1 shows a storage device with a storage chamber 5f and a transport line 9f in a plan view. Notwithstanding the preceding embodiments, the transport path is not rectilinear but curved, so that an outlet opening is arranged at a desired location.
- Fig. 12 shows a storage device with a storage chamber 5g and a transport path 9g.
- the transport path branches into sections 20 and 21, wherein the section 20 leads to an outlet opening 1 1 g and the section 21 to an outlet opening 1 Ig 1 .
- the transport path in this case fulfills the function of a fluid distributor.
- a storage device shown in FIG. 13 has two storage chambers 5h and 5h '.
- the transport section 23 has a meandering shape, which assists the mixing of the two fluids.
- the transport path therefore fulfills the function of a fluid mixer.
- the transport path can be used for accurate metering and further transport of a defined amount of fluid (metering).
- a reagent or sample amount is transferred into the transport channel until, for example, it has reached the through-opening 11 h, which can be monitored by visual observation in the case of a transparent flow cell, for example made of a transparent plastic.
- the pressurization of the reagent is stopped and the transport fluid in the chamber 5h 'subjected to pressurization. This leads to the further transport of the fluid located in the transport section 23 and thus to the further carrying out a defined quantity of reaction. With the help of blocking elements, this process can be repeated until the pantries are completely emptied.
- a storage device shown in FIG. 14 with a storage chamber 5i and a transport path 9i has an intermediate container arranged in the transport path, which is coated on the inside with a dry reagent. If the fluid flows through the intermediate container 24, the interior of which as well as that of the transport path opens up entirely through the fluid, the dry reagent is at least partially dissolved and transported in the fluid.
- the achievable interior space of the intermediate container 24 can be set very flat in accordance with the liquid pressure which can be adjusted and adjusted by the pressurization 14 or setting by the blocking element 16, and influence the dissolving behavior of the dry reagent in the desired manner.
- a storage device with a storage chamber 5 shown in Fig. 15 contains in a transport path 9j various containers 25, e.g. could be filled with different dry reagent materials.
- the embodiments of transport routes shown in FIGS. 11 to 15 can be combined with each other.
- the storage device thus assumes the functions of a flow cell.
- a downstream processing device no longer has any flow cell functions, such as e.g. an electrical or electrochemical sensor connected downstream of the storage device.
- a storage device having a storage chamber 5k shown in Fig. 16 is connected to a flow cell 2k.
- a base plate 3k of the flow cell 2k is arranged on a film 7k, by the bulge of which the storage chamber 5k is formed.
- the film 7k covers a channel 13k formed in the base plate 3k, which is connected via a passage opening 11k in connection with a transport path 9k of the storage device.
- a covering film corresponding to the film 4 could be mounted on the side of the base plate facing away from the channel 13, and further channels could be formed there, which, viewed in the projection, can intersect with the channel 13.
- additional functions can be achieved with the same production cost of the flow cell.
- the thickness of the base plate 3k is greater than the height of the storage chamber 5k, the chamber is protected against improper handling, especially in stack storage of the storage device. The handling of the storage device is thus safer overall.
- FIG. 17 shows different embodiments for predetermined breaking points, which extend immediately adjacent to a storage chamber over the entire width of a transport path and are designed as a welded or / and glued connection between two films.
- the dimension of the welded connection indicated by arrows in FIG. 17a which is preferably between 0.01 and 5 mm, in particular 0.1 and 2 mm, is decisive for the required opening pressure.
- the shape of the predetermined breaking point may deviate from a rectangle, e.g. have the arrow shape shown there. In this way, manufacturing technology easier to produce welds greater width can be formed without the required opening pressure increases proportionally with the width.
- Fig. 18 shows a storage chamber 51 formed by sheets 71 and 81.
- the sheets 71 and 81 are abutted and the volume enclosed by the sheets is zero.
- the films 71 and 81 are stretched in accordance with the degree of filling as in the case of a filled bag.
- the inclusion of the filling quantity is done by closing a last weld.
- the storage chamber can be completely emptied and the force for emptying does not increase, as in the embodiments described above, with the degree of emptying.
- the components of the devices described above are produced by mass production processes, wherein the films described are formed by deep drawing, base plates produced by injection molding and gluing or welding are used as connection technologies.
- Suitable materials are, in particular, plastics, in particular plastic films, but also metals and metal foils and / or composite materials, such as e.g. PCB material.
