A sampling and assay device comprises at least three chamber portions (1, 3, 4) connected together in a row. Each chamber portion (1, 3, 4) defines a chamber (11, 13, 27) and adjacent chambers (11, 13, 27) along the row are separated by respective partitions (14, 15). One end chamber (4) is capable of receiving a sample either on a swab or as a liquid. The other chambers (11, 13) contain reagent for performing the assay. Adjacent chamber portions (1, 3, 4) along the row are relatively movable towards each another. In respect of each pair of adjacent chamber portions (1, 3), one of the adjacent chamber portions (1) has the respective partition (14) fixed thereto and the other of the adjacent chamber portions (3) has a rupture member (17) arranged to rupture the respective partition (14) on relative movement of the adjacent chamber portions (1, 3). As a result, the sampling and assay device is capable of rupturing each partition (14, 15) simultaneously on relative movement of the chamber portions (1, 4) at the ends of the row towards each other. Also, each pair of adjacent chamber portions (1, 3) have respective connection portions (2a, 3a) mated together, the connection portions (2a, 3a) being designed to allow further chamber portions identical to an intermediate chamber portion to be connected into said row.

L'invention porte sur un dispositif d'échantillonnage et de dosage comprenant au moins trois parties de chambre (1, 3, 4) raccordées pour former une rangée. Chaque partie de chambre (1, 3, 4) forme une chambre (11, 13, 27), et des chambres adjacentes (11, 13, 27) le long de la rangée sont séparées par des cloisons (14, 15). Une chambre terminale (4) peut recevoir un échantillon soit sur un porte-coton, soit sous forme d'un liquide. Les autres chambres (11, 13) contiennent un réactif pour réaliser l'analyse. Des parties adjacentes des chambres (1, 3, 4) le long de la rangée peuvent relativement se déplacer les unes vers les autres. Concernant chaque paire des parties adjacentes des chambres (1, 3), à l'une de ces parties (1) est fixée une cloison (14), et l'autre de ces parties adjacentes (3) possède un élément de rupture (17) agencé de façon à rompre la cloison (14) lors du déplacement relatif des parties adjacentes des chambres (1, 3). En conséquence, le dispositif d'échantillonnage et d'analyse peut rompre chaque cloison (14, 15) simultanément lors du déplacement relatif des parties des chambres (1, 4) aux extrémités de la rangée, l'une vers l'autre. Chaque paire des parties des chambres adjacentes (1, 3) possède des parties de raccordement (2a, 3a) conçues pour permettre aux autres parties des chambres identiques à une partie de chambre intermédiaire d'être raccordée dans cette rangée.
