A device for sampling of biological liquid comprises a protecting lid, placed with the possibility of its moving, and test tube, closed on the front-end by the resilient hermetically fastened lid which can be pricked. On the one side the protecting lid has a canula, on which a medical needle is placed. The test tube is made of resilient material, the deformation size of which equals the necessary dose of biological liquid. |
