DEVICE FOR PREPARATION OF A DRIED AMOUNT OF A LIQUID, IN PARTICULAR BLOOD, ABSORBENT SAMPLE HOLDERS Russian patent published in 2020 - IPC B01L3/00 G01N1/40 A61B5/15 B65D83/04 

FIELD: medical equipment.

SUBSTANCE: apparatus for preparation of sample holders, each designed to receive a given amount of liquid, for example blood, having: a tube with a receiving space inside to accommodate a plurality of sample holders stacked in a longitudinal direction of the tube; located on the front end of the tube holding device for unilateral limitation of the receiving space, and installed on rear end of tube in longitudinal direction of tube with possibility of shifting pusher, which by its one end in form of a pusher head enters the tube to limit the receiving space opposite to the holding means and which by its other end in the form of a pusher handle protrudes from the tube, wherein the retainer is elastic, on one side, to retain the sample holders in the receiving space and, on the other side, for controlled release of sample holders separately from receiving space when force is applied by pusher; on pusher at least in its handle area multiple wings are located in longitudinal direction of pusher at distance from each other, wherein adjacent wings in circumferential direction of pusher are shifted each by a predetermined circumferential angle (α) relative to each other; and on rear end of tube provided through hole, which is intended to enable passage of pusher wings only in one given circumferential angular position.

EFFECT: technical result is higher efficiency of sampling.
