1. A device for the extraction of blood or a blood compound, comprising:
a tube that extends along a longitudinal axis and which has a lateral wall, a closed distal end, a proximal end opposite the distal end and an interior cavity communicated with an exterior by an opening at the proximal end;
a piston assembly that is movable along the interior cavity of the tube, the piston assembly delimiting a space between the piston assembly and the distal end of the tube;
a handle assembly, having a gripping portion and an end portion, and
a perforable sealing element;
wherein the device is configured to adopt an advancing position in which the handle assembly pushes the piston assembly towards the distal end and is not clipped to the piston assembly, and in which air in the space is expelled through the piston assembly and/or via a space between the piston assembly and the lateral wall of the tube; and
wherein the device is configured to adopt a retreating position in which the end portion of the handle assembly is clipped to the piston assembly and pulls the piston assembly towards the proximal end and in which the piston assembly and the perforable sealing element seal the space between the piston assembly and the distal end of the tube.
