1. A system for sample collection, the system comprising:
- a tube assembly comprising;
a first tube having first and second ends, the first end of the first tube having an outer diameter and having a first tube opening therein;
a second tube having a first end and a second end, the first end of the second tube having a second tube opening therein and the second end of the second tube having a third tube opening therein, the second tube opening having an inner diameter greater than the outer diameter of the first end of the first tube;
a securing mechanism operable to secure the first tube and the second tube such that the first end of the second tube extends beyond the first end of the first tube, with the first end of the first tube inside the first end of the second tube creating an interstitial space about the first tube at the first end of the second tube; and
a seal, wherein when the seal is disposed against the first end of the second tube to form a barrier, wherein a biological sample can pass from the first end of the first tube by way of the interstitial space into the third tube opening of the second end of the second tube;
a sample source fluidly coupled to the second end of the first tube; and
a collection vessel comprising a collection medium, wherein the collection medium is capable of binding biological samples, and wherein the collection vessel is positioned to receive a fluid from the tube assembly.

Abstract
A tube assembly, system and method for biological sample collection. In one embodiment, the tube assembly of the present disclosure includes a first tube, a second tube, a mechanism for securing the first and second tubes. The securing mechanism orients the first ends of the first and second tubes in a manner such that the first end of the second tube extends beyond the first end of the first tube to create an interstitial space between the outer diameter of the first tube and the inner diameter of the second tube.

9. A method of sample collection, the method comprising the steps of:
-
introducing a biological sample into a tube assembly of a system of sample collection from a sample source, the system comprising; the tube assembly comprising; a first tube having first and second ends, the first end of the first tube having an outer diameter and having a first tube opening therein; a second tube having a first end and a second end, the first end of the second tube having a second tube opening therein and the second end of the second tube having a third tube opening therein, the second tube opening having an inner diameter greater than the outer diameter of the first end of the first tube; a securing mechanism operable to secure the first tube and the second tube such that the first end of the second tube extends beyond the first end of the first tube, with the first end of the first tube inside the first end of the second tube creating an interstitial space about the first tube at the first end of the second tube; a seal, wherein when the seal is disposed against the first end of the second tube to form a barrier, wherein a biological sample can pass from the first end of the first tube by way of the interstitial space into the third tube opening of the second end of the second tube; the sample source fluidly coupled to the second end of the first tube; and a collection vessel comprising a collection medium, wherein the collection medium is capable of binding biological samples, and wherein the collection vessel is positioned to receive a fluid from the tube assembly; and depositing the biological sample from the tube assembly on the collection media; wherein the biological sample deposited on the collection media is undiluted. - View Dependent Claims (10, 11, 12, 13, 14)
