摘要:
The present invention relates to 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 present 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 were discovered to further improve penetrability of the cap. In this way, substances can be dispensed into or withdrawn from the vessel without having to physically separate the cap from the vessel.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 (e.g., pipettes) and which aid in creating air gaps for venting air from the interior of a collection device to prevent or minimize the release of fluid sample in the form of an aerosol or bubbles.

The invention relates to a sealed collection device comprising a vessel closed with a penetrable cap, the collection device containing a specimen retrieval device positioned along a side wall of the vessel and having proximal portion positioned between an inner wall of the cap and the side wall of the vessel. The invention relates further to a method for obtaining a fluid substance from the sealed collection device comprising the steps of: a) penetrating the cap with a fluid transfer device; b) entering the collection device so that the specimen-retrieval device does not substantially interfere with the movement of the fluid transfer device; c) drawing the fluid substance into the fluid transfer device; and d) removing the fluid transfer device from the collection device.

摘要:
A reaction receptacle apparatus (160) includes one or more individual receptacles (162) for containing chemical or biological substances. The one or more receptacles (162) are arranged to be engaged by tubular elements of a substance transfer device for transferring substances into or out of the individual receptacles (162). Multiple receptacles (162) are coupled to one another by a connecting rib structure (164) that defines straight shoulders (165) along opposite sides of the reaction receptacle apparatus (160), and the shoulders (165) support the apparatus within reaction receptacle apparatus carrying structures. A contact-limiting element holding structure (176) for holding contact-limiting elements (170), such as protective tips for tubular elements, is associated with each individual receptacle (162) and holds a contact-limiting element (170) in an operative orientation so as to be operatively engageable by the tubular element of the substance transfer device. A receptacle apparatus (160) manipulating structure (166) permits the reaction receptacle apparatus to be moved from one location to another by a robotic manipulating device, and an information panel(174) presents a surface on which human and/or machine readable information may be placed.
