Definitions
- the invention relates to a device for the stepwise transport of liquid by a plurality of fluidically arranged in series reaction chambers taking advantage of capillary forces, it being the fluids preferably to be examined sample liquids.
- sample liquids In the most diverse application areas of analytics and diagnostics it is necessary to examine sample liquids. They are used Occasionally, assays require that the sample fluid be sequential be contacted with different reagents. With regard the automation of such assays is beneficial if one is able to to gradually transport the sample fluid to be examined.
- An object of the invention is a device for stepwise transport of liquid, in particular sample liquid to be examined to create, which has a fairly simple structure and convenient and easy is manageable and works reliably.
- the channel of the device through which Liquid to be transported, designed accordingly.
- the channel is at least two Vent holes in fluid communication, which closed in their initial state are.
- the fluid connection of the vents to the channel occurs at spaced along the channel joints.
- the vents can directly form the joints, ie directly in the channel wall or a substrate in which the channel is formed is, be arranged.
- Degass bleed ducts that end in the vents.
- the Venting channels can be used for liquid transport by means of capillary forces be designed. However, this is not mandatory as the vent lines primarily serve the vent.
- liquid enters the channel by the channel for example, from extends from a sample receiving chamber, so is the transport of liquid through the channel as long as the channel (at its end) and the vents are closed.
- the transport of liquid through the channel will now be in the flow direction opened channel of the first vent, so passes liquid to be in fluid communication with the open vent Junction of the channel and thereby fills this junction upstream chamber; the further transport of the liquid through the channel beyond this junction is not possible because of the adjoining Part of the channel is closed to the outside.
- Only when the in Flow direction is opened next vent fills the Channel section between the aforementioned junction and the next vent associated connection point as well as in this Channel section disposed chamber with liquid.
- the chambers can empty or with substances, inserts (porous bodies or the like) or capillary forces generating devices, such as e.g. Surface finishes, be equipped.
- reagents preferably immobilized, are arranged within the In the individual channel sections. By contact with the liquid the reagents are mobilized and can react with the fluid.
- vents can in the simplest case directly in the wall be arranged of the channel. The joints then fall so with the Vents together. Alternatively, it is also possible that of the Branching off connection points from venting ducts in the vents end up.
- a (re-) closure of the vents after the liquid front the assigned junctions of the channel has passed is not mandatory, but it can be done. Appropriately It is however, if it succeeds, that the liquid maximally up to the vent opening flows and ensures that the liquid does not escape Vent can emerge. This is with mechanisms leading to Transport of the liquid Take advantage of capillary forces, easily possible, Appropriately in this regard, it is when the vents are dimensioned accordingly, so that due to surface tensions the liquid is an outlet of the same from the openings omitted.
- the transport through one of a connection point to the vent leading venting channel also takes place expediently taking advantage of capillary forces.
- the vent also be preceded by a capillary stop. This is e.g. as hydrophobic (partial) surface of the venting channel or as hydrophobic Vent or formed as a gradual expansion of the channel system.
- the opening of the vents is advantageously carried out selectively by means individual cover elements or a common cover element, with the vent openings according to their arrangement along the Selective release of channels.
- it is the Cover element around an adhesive strip, the one or more vents is glued.
- the Cover element for example, be peelable or punctiform.
- the lid member meltable or by initiation a reaction is dissolved or permeable to air.
- the lid member is an adhesive strip over the Vents of a substrate or the like. Carrier is placed, in which the inventive Channel system is formed.
- For melting the lid elements it is for example advantageous; if these cover elements with a or more heating elements are thermally coupled. By control the heating elements are thus selectively melted and lid elements thus exposing vents.
- the initiation of a lid element dissolving reaction can by Contacting the lid member with a reactant made from the outside. It should be only for the sample liquid inert reaction mixtures arise.
- a hydrophilic material e.g., gel, such as agarose, sucrose or the like. Polysaccharides.
- the device according to the invention can be used, for example, for a blood test be in which the blood to be examined in a first reaction chamber react with a first antibody or conjugate and then in a second chamber on the bound first antibodies bind second antibody.
- Task for the blood to be examined then happens after that Exposing the first vent to the associated junction extending channel portion of the channel in which the first Reaction chamber with the first antibody or the conjugate arranged is.
- the blood sample to be examined with the partially bound antibodies by exposing the flow direction next vent in a second channel section transferred, in which the second reaction chamber with the second antibodies is arranged. Subsequently, by exposing a further vent opening or by exposing the end of the channel, the sample liquid in this further transported or transported out of this.
- the device according to the invention can advantageously also have several of the above described (sample liquid transport) channels with vents respectively. All of these channels are fluidically parallel to each other, extend from a sample receiving arrangement with a common Sample receiving chamber or more individual, the channels respectively assigned sample receiving chambers and preferably have mutually equal length channel sections between the individual connection points on.
- the connecting points respectively associated vents are arranged immediately adjacent to each other and can be advantageously exposed with one and the same lid member.
- Fig. 1 shows the basic structure of the capillary channel system according to the invention 10.
- the capillary channel system 10 is in a substrate 12 (Plastic body or the like.) Formed and has a channel 14 which has a (in fluid communication with a reservoir, not shown) inlet opening 16 and an outlet opening 18. Liquid that is in the Channel 14 is in the channel taking advantage of capillary forces transported.
- the channel 14 has a plurality of (four in the embodiment) connection points 20,22,24 and 26, from which branch off vent lines 28,30,32,34, which end in vents 36,38,40,42.
- the channel 14 is through the connection points 20,22,24,26 into individual channel sections 44,46,48 divided; in each channel section 44,46,48 is a reaction chamber 50,52,54.
- the capillary channel system 10 shown in FIG. 1 can be selectively entrained as follows Fill the liquid.
- vents are 36,38,40,42 and the outlet 18 of the channel 14 closed. Will now be in the flow direction 56 (see arrow) first vent opening 36 is opened, then sample liquid, which is present at the inlet 16 of the channel 14, to the junction 20 and in the vent channel 28 to the vent opening 36. By shortening the venting channels 28 may be the dead volume of the capillary channel system 10 are minimized.
- the vents 36 can also directly in the Wall of the channel 14 may be formed. After the opening 36 exposed Thus, the liquid front within the channel 14 migrates to the Joint 20; In any case, no liquid enters (yet) into the Channel section 44.
- next vent opening 40 is opened, it is repeated previously described operation for the further channel section 46, so that Finally, the situation according to FIG. 3 sets.
- next Vent 42 eventually becomes the next channel section 48 with liquid filled, which is shown in Fig. 4. If you then the outlet 18 of the channel 14 opens, the liquid passes out of the channel 14 in a (not shown) collecting container or a collecting chamber.
- the capillary channel system 10 described above can still via so-called Capillary stops have, which only after impressing a pressure pulse on the Be overcome liquid, followed by the further transport of the Liquid in turn is induced by capillary forces.
- Such capillary stops could, for example, at the outputs of the reaction chambers 50,52,54 be formed or arranged.
- the selective transport of the liquid through the Kapillarkanalsystem 10 takes place in such a case so alternately by exposing vents and imprints one Pressure pulse.
- a vent opening 36 is arranged before the first reaction chamber 50. This could be omitted together with the vent line 28, as shown in FIGS. 5-7 is shown.
- FIG. 5 to 7 is a second embodiment of a capillary channel system 10 'shown.
- the basic structure of the capillary channel system 10 'of FIGS. 5-7 is identical to that shown in FIGS. 1 to 4.
