Definitions

  • the invention comprises a connection device for the fluidic contacting of microfluidic chips, according to the preamble of claim 1.
  • a macrofluidic conduit with an elastic sleeve is lengthened for contacting microfluidic platforms
  • the sleeve is inserted in a contact body which has a recess with the outside diameter of the sleeve, and the elastic sleeve is selected so that it projects beyond the contact body in its axial extent
  • the elastic sleeve is compressed in its receptacle in the contact body and seals the microfluidic chip and contact body against each other
  • the contact body has holes on its side facing away from the microfluidic chip for inserting macrophilic Uidischen lines that correspond to the inner diameter of the sleeve.
  • a macrofluidic line can thus be inserted into the elastic sleeve.
  • the elastic sleeve undergoes a change in cross-section of the inside diameter and thus seals the transition between the macrofluidic line and the sleeve.
  • This embodiment has the disadvantage that the support surface is very small, and the sealing surface is prone to contamination. In addition, inaccuracies in the position of the microfluidic chip can not be compensated.
  • connection device for contacting microfluidic chips, which provides a high degree of tightness available, can be quickly and easily connected to the microfluidic chip and released again.
  • the object is solved by the features of claim 1.
  • the connecting device has at least one connector, wherein a connector comprises a sleeve, at the end of which there is a flange ring.
  • the flange ring lies between the facing surfaces of the carrier plate and the microfluidic chip to be contacted.
  • This flanged ring attached to the sleeve improves the sealing behavior. Contrary to the prior art, in which only a small footprint, the annular surface between the inner and outer diameter is sealed, the sealing surface is significantly increased by the projections of a flange. In addition, the power line changes such that the received in the contact body sleeve structure undergoes no narrowing of the cross section or its inner diameter. This ensures a reproducibility of the flow properties with improved seal.
  • the molding of a flange seal on an elastic sleeve has the advantage that an equivalent seal can be achieved with less contact force.
  • a more or less attenuating layer results between the fluid connection plate and the microfluidic chip. This avoids tension of the fluid chip and guarantees its function.
  • the flange has a compensation function, which makes it possible to compensate for minor bumps or tolerances in the production of the fluid chip.
  • the sleeve and the flange are integrally formed. This has the advantage of an optimal introduction of force. In addition, it avoids a small gap in which dirt particles can penetrate.
  • the handling is significantly improved by one-piece fittings.
  • the flange rings are glued or sprayed directly onto the carrier surface. This improves both the handling when connecting the carrier plate with the microfluidic chip, as well as during cleaning.
  • a microfluidic chip can be contacted very quickly and nevertheless reliably releasably.
  • the centering can preferably be done via the connection plate.
  • this type of connection several connection points of a fluid chip can be contacted simultaneously. This saves a lot of time compared to conventional screwed connections, which all have to be individually screwed into the respective receptacles.
  • the sealing connections are made of PDMS or other resistant and elastic plastic compounds.
  • the recess in the flange has a slightly smaller diameter than the sleeve and a slightly larger diameter than the microfluid connection opening to be contacted.
  • the opening cross section in the flange corresponds to the inner diameter of the hose. This results in an exceptionally small dead volume.
  • the plastic connectors are preferably already integrated into the carrier plate or can be used in an alternative embodiment later in the carrier plate.
  • the cross section of the recess in the carrier plate for receiving the sleeve is chosen to be slightly smaller than the outer diameter of the plastic sleeve. This leads to a compression of the sleeve in the radial direction, which significantly improves the tightness relative to the hose.
  • the flange ring can be designed so that the inner diameter of the flange ring corresponds to that of the line. In particular, then lies the annular surface of the line on the flange.
  • FIG. 1 shows an exploded view of a microfluidic system comprising the connecting device according to the invention
  • Fig. 2 is a sectional view of the composite microfluidic system
  • Fig. 3 is a detail sectional view of the connecting device.
  • FIG. 1 shows an exploded view of a microfluidic system, comprising a base plate, a microfluidic chip, a connection plate with connectors inserted, and a holding device 18 for receiving a quick-release fastener 20.
  • the holder 18 is mounted on the base plate 10. Between the holder 18 of the microfluidic chip 12 is inserted.
  • the support plate 14 has on the microchip zugewanden side recesses into which the connectors 16 are inserted. Recesses are provided on the side remote from the microchip into which a macrofluidic line or a hose can be inserted.
  • the macrofluidic tube is inserted into the sleeve 22 of a connector.
  • centering pins 24 are provided, which extend through the bottom plate, the microfluidic chip and the carrier plate, in order to ensure that the connection openings of the microfluidic chip and that of the connectors 16 are aligned with one another.
  • microfluidic chips can be contacted in a simple manner. This is especially true when all microfluidic chips have the openings for access to the microfluidic system within the chip at the same position. In this way, different chips can be quickly and easily inserted and removed in an appropriate device.
  • the connections have a high flexibility with high seal and low dead volume.
  • Fig. 2 shows a sectional view in which also the tube inserted into a connector is shown.
  • This illustration shows the bottom plate 10, the microfluidic chip 12, the carrier plate 14, an adjusting pin 22 and a connector 16 installed in the carrier unit.
  • the carrier is braced against the bottom plate. This results in a compression of the integrally formed on the sleeve 22 flange 26 in the area in which this is between the support plate 14 and the microfluidic chip 12.
  • In the opening of the microfluidic chip 12 is aligned or coaxially aligned with the associated connector 16.
  • FIG. 3 shows a detailed sectional view of a connector 16 in a carrier plate 14, wherein the connector 16 is placed on a microfluidic chip 12.
  • the connector 16 comprises a sleeve 22 and a flange ring 26 integrally formed on it.
  • the end of a macrofluidic hose 28 is inserted into the sleeve.
  • the inner diameter of the recess in Make the flange so that it corresponds to the inner diameter of the hose. This ensures that no dead volume between tube 30 and sleeve 22 is formed, provided that the tube 30 is pushed up to the flange 26.
  • the inner diameter of the flange ring 26 is dimensioned such that it is slightly larger than the opening of the fluid chip. As a result, tolerances in the connection can be compensated and a contact can be ensured despite inaccuracies.
