An apparatus and method for sealing a fluid sample collection device, comprising: loading a fluid sample collection device with a fluid sample, said device comprising a housing having at least one substantially planar surface that includes an orifice in fluid communication with an internal fluid sample holding chamber which terminates at an internal capillary stop; and slidably moving a sealing element over at least a portion of said substantially planar surface in a way that displaces any excess fluid sample away from the orifice, seals the fluid sample within said holding chamber, and inhibits the fluid sample from prematurely breaking through the internal capillary stop.

La présente invention concerne un appareil et un procédé qui permettent de fermer hermétiquement un dispositif de collecte de prélèvement liquide, lequel procédé consiste à : charger d'un prélèvement liquide un dispositif de collecte de prélèvement liquide, lequel dispositif de collecte de prélèvement liquide comprend un logement comportant au moins une surface sensiblement planaire munie d'un orifice en communication fluidique avec une chambre interne de retenue de prélèvement liquide délimitée par un butoir capillaire interne ; et déplacer par coulissement un élément d'étanchéité par-dessus au moins une partie de ladite surface sensiblement planaire d'une manière qui fait s'éloigner tout excédent de prélèvement liquide de l'orifice, qui enferme hermétiquement le prélèvement liquide à l'intérieur de la chambre précitée, et qui empêche le prélèvement liquide de rompre prématurément le butoir capillaire interne.
