Device for making available absorbent sample carriers having a quantity of dried liquid, in particular blood

A device (100) for providing sample carriers (200-n), which are each constructed to receive a predetermined quantity of a liquid, comprising:

• a tubelet (110) with a receiving chamber (112) in an interior thereof for reception of a plurality of sample carriers stacked in a longitudinal direction (L) of the tubelet (110);
• a holding means (120), which is arranged at a front end of the tubelet, for bounding the receiving chamber (112) at one end;
• and
• a plunger (130), which is mounted at a rear end of the tubelet to be displaceable in the longitudinal direction (L) of the tubelet, the plunger having a plunger head (132) which enters into the tubelet
• (110) for bounding the receiving chamber oppositely to the holding means
• (120) at one end of the plunger (130) and
• a plunger grip (134) which projects out of the tubelet at an opposite end of the plunger (130),
• wherein the holding means (120) is of resilient construction for retaining the sample carriers (200-n) in the receiving chamber (112) and for controlled individual release of the sample carriers (200-n) from the receiving chamber (112) under action of a force by the plunger (130);
• wherein a plurality of fins (140-n) is arranged at the plunger (130) at least in a region of the plunger grip thereof to be spaced from one another by a spacing in longitudinal direction (L) of the plunger, wherein adjacent fins are arranged to be offset relative to one another in a circumferential direction (U) of the plunger (130) each time by a predetermined circumferential angle (α), and
• wherein a passage opening (114) formed to allow the fins (140-n) of the plunger (130) to pass only in at least one predetermined circumferential angular position is provided at the rear end of the tubelet (110).
