Patent ID: 7691326

Claim:
A system for collection of a sample, comprising: a vial, suitable for containment of a collected sample, said vial defining a main chamber and including an outer rim, said outer rim being structured and arranged to selectively enable communication between said main chamber and an area exterior of said main chamber; a liquid reservoir assembly having an external cylinder, an internal cylinder and a frangible annular membrane, said external cylinder including a vial end, a cap end, and an internal wall; said internal cylinder being oriented concentrically within said external cylinder and having a distal end, a proximal end and an external wall, said frangible annular membrane being positioned intermediate said external cylinder and said internal cylinder, said vial end of said external cylinder and said distal end of said internal cylinder being interconnected by said frangible, annular membrane, said internal cylinder being connected to a perimeter of said frangible, annular membrane, said liquid reservoir assembly being structured and arranged to contain a selected liquid, wherein said internal cylinder defines a passageway in communication with said main chamber, said external cylinder at said vial end or said internal cylinder at said distal end defining liquid reservoir threads and said outer rim defining vial threads engaged with said liquid reservoir threads; a lid sealingly seated at said cap end, said lid including an opening in registration with said passageway, wherein said internal wall, said external wall, said frangible, annular membrane and said lid collectively define an enclosed liquid reservoir; an extension rod having a proximal rod end and a distal rod end including a tip, said extension rod being inserted through said opening, passageway and outer rim and into said main chamber; a cap associated with said proximal rod end and structured and arranged to seat adjacent said lid, to seal against fluid communication between said passageway and said area exterior said main chamber, and to releasably engage said internal cylinder of said liquid reservoir assembly when seated adjacent said lid; wherein said cap is constructed to transfer a rotational torque force applied to said cap to said internal cylinder; and wherein said said internal cylinder is constructed to be rotatable relative to said external cylinder wherein a rotation of said internal cylinder relative to said external cylinder applies a rotational torque force to said perimeter of said frangible, annular membrane to effect a torque force on said frangible annular membrane sufficient to cause a breach in said frangible, annular membrane thereby placing said enclosed liquid reservoir and said main channel in fluid communication.
