Abstract
A fluid cartridge, comprising a channel layer within which at least one circumferentially sealed fluid channel is formed, the channel layer comprising a substrate and an elastic layer fixedly arranged on the substrate, wherein the substrate has a rigidity being greater than that of the elastic layer, and wherein the at least one fluid channel is defined on at least one side thereof by the elastic layer.
Claims26
A fluid cartridge, comprising:
- a channel layer within which at least one circumferentially sealed fluid channel is formed, the channel layer comprising:
- a substrate, and
- an elastic layer fixedly arranged on the substrate,
- a microfluidic chip being located in or on the channel layer and being in fluid connection with the at least one fluid channel;
- one or more fluid storage lines and/or one or more fluid storage containers being arranged in or on the channel layer and being in fluid connection with the at least one fluid channel;
- wherein the substrate has a rigidity being greater than that of the elastic layer;
- wherein the at least one fluid channel is defined on at least one side thereof by the elastic layer;
- wherein the one or more fluid storage lines are non-integrally formed with regard to the channel layer and are removably and/or replaceably arranged in or on the channel layer;
- wherein the at least one fluid channel forms a closed loop with the microfluidic chip and the one or more fluid storage lines and/or the one or more fluid storage containers being connected in series therebetween;
- wherein two separate fluid channels are formed within the channel layer which are connected with each other via a dummy which is replaceable by a fluid storage line or a fluid storage container containing a sample therein.

A fluid cartridge, comprising:
- a substrate in which a plurality of circumferentially sealed chambers or channels is firmed, and
- a plurality of fluid storage devices non-integrally formed with respect to the substrate and connected in series via the plurality of chambers or channels, wherein the respective fluid storage device is a fluid storage line or a fluid storage container, each fluid storage device comprising a different fluid therein,
- and a first and a last of the plurality of fluid storage devices having a respective free end serving as connection end,
- a microfluidic chip being located in or on the upper surface of the substrate and being in fluid connection with one of the two connection ends;
- wherein the one or more fluid storage lines are non-integrally formed with regard to the channel layer and are removably and/or replaceably arranged in or on the channel layer;
- wherein the plurality of the chambers or channels form a closed loop with the microfluidic chip and the plurality of fluid storage devices being connected in series therebetween;
- wherein two separate channels are connected with each other via a dummy which is replaceable by a fluid storage line or a fluid storage container containing a sample therein.
