Abstract
A device and a plurality of microfluidic platforms for taking up and especially studying or manipulating a sample liquid, a measuring instrument for use with the device and platforms, and a process for performing the studying or manipulating of the sample liquid. Very simple, hygienic and user-friendly handling is enabled in that the platforms which are connected to one another in a sealed state and can each be individually separated and individually, preferably simultaneously, opened for taking up of a sample, such as blood, for, e.g., performing a glucose determination.
Claims30
Device with a plurality of microfluidic platforms for taking-up and studying or manipulating a sample liquid, the platforms, in a sealed state, being at least one of directly joined to one another and located on a common carrier, and wherein the each of the platforms is adapted to be individually separated and individually opened.
Measuring instrument for studying a sample liquid by means of a microfluidic platform, wherein the measuring instrument has means for holding a multiplicity of single-use platforms.
Process for studying or manipulating a sample liquid by means of a microfluidic platform which takes up the sample liquid, comprising the steps of:
- delivering a plurality of platforms which in the sealed state and which are at least one of directly joined to one another and located on a common carrier,
- individually opening and separating the platforms as needed, and
- immediately following opening and separating of a platform, performing said studying or manipulation of the sample liquid.
Microfluidic platform assembly, comprising:
- a plurality of microfluidic platforms for taking-up and studying or manipulating a sample liquid, the platforms, in a sealed state, being covered by a common or continuous covering, which covers at least one of an opening of a take-up channel for taking up the sample liquid and an opening of a vent channel of each platform,
- wherein the each of the platforms is adapted to be individually separated and is adapted to be individually opened by removing at least a portion of the covering, so that at least one of said channels is opened.
