CA 2678141

The invention relates to a collection device comprising a cap which can form an essentially leak-proof seal with a vessel capable of receiving fluid specimens for clinical analysis and diagnosis. To minimize potentially contaminating contact between the fluid specimen and humans or the environment, the invention features a cap which is penetrable by a plastic pipette tip or other fluid transfer device, and may include a plurality of striations which further improve penetrability of the cap. Substances can be dispensed into or withdrawn from the vessel without having to physically separate the cap from the vessel. Also featured are fluid transfer devices having rib structures which aid in improving the penetration and/or strength characteristics of standard fluid transfer devices and creating air gaps for venting air from the interior of the collection device to prevent or minimize release of fluid sample in the form of an aerosol or bubbles.

L'invention a trait à un dispositif de collecte comprenant un capuchon qui peut former un joint essentiellement étanche avec un contenant capable de recevoir des échantillons liquides en vue d'une analyse et d'un diagnostic clinique. Pour minimiser la contamination potentielle par contact entre l'échantillon liquide et les humains ou l'environnement, l'invention possède un capuchon qui est perforable par une pipette en matière plastique ou un autre dispositif de transfert de liquide, et peut inclure plusieurs stries qui augmentent encore la perforabilité du capuchon. Les substances peuvent être introduites dans le contenant ou en être extraites sans avoir à séparer physiquement le capuchon du contenant. Sont également décrits des dispositifs de transfert de liquide possédant des structures nervurées qui aident à améliorer la pénétration et/ou les caractéristiques en matière de résistance des dispositifs de transfert de liquide courants et à créer des espaces libres pour ventiler l'air de l'intérieur du dispositif de collecte afin d'empêcher ou de minimiser la libération de l'échantillon liquide sous forme d'aérosols ou de bulles.
