Abstract

A biological fluid collection device includes a collection module and an outer housing. The collection module includes a housing comprising a first end having a sample introduction opening, a second end having a sample dispensing opening, and a passageway extending between the sample introduction opening and the sample dispensing opening. A mixing chamber and a holding chamber are in fluid communication with the passageway such that a sample introduced into the sample introduction opening passes through the mixing chamber and subsequently into the holding chamber. The biological fluid collection device further includes a closure covering the first end, a cap covering the second end and including a vented plug, and an activation member adapted to force a sample contained in the holding chamber out of the sample dispensing opening. The collection module is positioned inside of the outer housing and the closure closes the open end of the outer housing.

Claims

1. A biological fluid collection device comprising:

a collection module comprising;

a housing comprising;

a first end having a sample introduction opening;

a second end having a sample dispensing opening;

a passageway extending between the sample introduction opening and the sample dispensing opening; and

a holding chamber in fluid communication with the passageway;

a closure covering the first end of the housing;

a cap covering the second end of the housing and having a vented plug, the cap adapted to allow air to pass from the passageway of the collection module through the cap and the vented plug while preventing a blood sample from passing therethrough; and

an activation member adapted to force a sample contained in the holding chamber out of the sample dispensing opening; and

an outer housing having an open end and a closed end,

wherein the collection module is positioned inside of the outer housing and the closure closes the open end of the outer housing.

2. The biological fluid collection device of claim 1, further comprising a mixing chamber in fluid communication with the passageway, wherein a sample introduced into the sample introduction opening passes through the mixing chamber and subsequently into the holding chamber.

3. The biological fluid collection device of claim 2, wherein the mixing chamber includes an anticoagulant adhered to an interior of the mixing chamber.

4. The biological fluid collection device of claim 2, wherein the mixing chamber is filled with an open cell foam.

5. The biological fluid collection device of claim 2, wherein the mixing chamber is positioned closer to the first end of the housing than the holding chamber such that a blood sample introduced into the sample introduction opening passes through the mixing chamber before passing into the holding chamber.

6. The biological fluid collection device of claim 1, wherein the holding chamber is defined by an elastic sleeve surrounding the housing and a recess in the housing.

7. The biological fluid collection device of claim 6, wherein the activation member is at least a portion of the elastic sleeve defining the holding chamber such that, when the cap is removed from the collection module, an inward pressure on the portion of the elastic sleeve defining the holding chamber toward the recess in the housing forces the blood sample in the holding chamber out of the sample dispensing opening.

8. The biological fluid collection device of claim 1, wherein the vented plug is a porous plug.
