Patent

CA 2419714

A device (8) comprising a chamber (25) having a first open end (3) and a second closed end (4), an elongate member (11) having first and second open ends (9, 10), and sealing means providing a seal between the elongate member (11) when received in the chamber (25). The second end (10) of the elongate member is slidably movable from a first position within the chamber (25) to a second position within the chamber (25) causing a change in pressure within the chamber (25). The device enables sample collection and analysis to be performed in a single chamber (25). Devices and methods including wax and reagent compositions within the chamber (25) are disclosed.

L'invention concerne un dispositif (8) comprenant une chambre (25) dotée d'une première extrémité ouverte (3) et d'une seconde extrémité fermée, (4), un élément de forme allongée (11) comprenant des première et seconde extrémité ouvertes (9, 10) ainsi que des moyens de scellement formant un scellement entre l'élément de forme allongée (11) et la chambre (25), lorsqu'ils sont logés dans celle-ci. La seconde extrémité (10) de l'élément de forme allongée peut se déplacer par coulissement entre une première position, dans la chambre (25), et une seconde position, dans la chambre (25), ce qui provoque un changement de pression dans cette chambre (25). Ce dispositif permet de recueillir des échantillon et de les analyser dans une seule chambre (25). L'invention concerne encore des dispositifs et procédés comprenant des compositions à base de réactifs et de cires, placés dans la chambre (25).
