Abstract
The present invention relates to a method and a device for contacting a microfluidic structure. The device comprises a receptacle for the microfluidic structure and also a contact unit. According to one aspect of the invention, the contact unit has at least one hollow needle, which is designed for piercing a layer of elastic material which is provided on the microfluidic structure.
Claims33
A device for contacting a microfluidic structure,
- said microfluidic structure having at least one microchannel and one access opening connected to said microchannel for introducing a first fluid into said microchannel, a layer of elastic material arranged on the microfluidic structure for closing off said access opening,
- said device comprising a receptacle for housing the microfluidic structure, and a contact unit having at least one fluid channel that is arranged to be connected to said access opening,
- whereby said contact unit comprises at least one hollow needle that is connected to said fluid channel and designed for piercing said layer of elastic material.
A device for contacting a microfluidic structure,
- said microfluidic structure having at least one microchannel and one access opening connected to said microchannel for introducing a first fluid into said microchannel, a layer of elastic material arranged on the microfluidic structure for closing off said access opening,
- said device comprising a receptacle for housing the microfluidic structure, and a contact unit having at least one fluid channel that is arranged to be connected to said access opening,
- whereby said contact unit comprises at least one hollow needle that is connected to said fluid channel and designed for piercing said layer of elastic material,
- wherein said layer of elastic material is provided with at least one recess facing said microfluidic structure, whereby said recess is arranged above said at least on access opening.
A microfluidic structure, in particular for pharmaceutical, chemical or biochemical analysis of fluidic substances, said microfluidic structure having at least one microchannel and at least one access opening connected to said microchannel, whereby a layer of elastic material is provided which closes off said access opening.
A microfluidic structure, in particular for pharmaceutical, chemical or biochemical analysis of fluidic substances, said microfluidic structure having at least one microchannel and at least one access opening connected to said microchannel, whereby a layer of elastic material is provided which closes off said access opening, wherein said layer of elastic material comprises at least one recess facing said microfluidic structure and arranged above said at least one access opening.
A microfluidic structure, in particular for pharmaceutical, chemical or biochemical analysis of fluidic substances, said microfluidic structure having at least one microchannel and at least one access opening connected to said microchannel, whereby a layer of elastic material is provided which closes off said access opening, wherein said layer of elastic material is provided with a predetermined braking point that is located above said access opening.
A method for making contact to a microfluidic structure, said microfluidic structure having at least one microchannel and one access opening connected to said microchannel for introducing a first fluid into said microchannel, said method comprising the steps of:
- arranging a layer of elastic material above said access opening for closing off said access opening,
- piercing said layer of elastic material by means of at least one hollow needle;
- and
- introducing said first fluid into said microchannel through said at least one hollow needle.
