Method for removing a fluid substance from a collection device
First Claim
1. A method for removing a fluid substance from a collection device containing a specimen retrieval device, the method comprising the steps of:
- a) positioning at least a portion of the specimen retrieval device along an inner surface of a side wall of a vessel having an open end and a closed end by fixedly associating a penetrable cap with the open end of the vessel, wherein the vessel and the cap compose the collection device;
b) penetrating the cap with a fluid transfer device, wherein the position of the specimen retrieval device within the collection device is such that the specimen retrieval device does not substantially interfere with the movement of the fluid transfer device into or out of the vessel;
c) drawing at least a portion of the fluid substance into the fluid transfer device, wherein the fluid substance is contained in the vessel; and
d) removing the fluid transfer device from the collection device.

Abstract
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 In this way, substances can be dispensed into or withdrawn from the vessel without having to physically separate the cap from the vessel.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 and caps having surface ribs and/or grooves which aid in creating passageways for venting displaced air from a penetrated collection device.
