Abstract

A biological fluid collection device that receives a sample and provides flow-through blood stabilization technology and a precise sample dispensing function for point-of-care and near patient testing applications is disclosed. A biological fluid collection device of the present disclosure is able to effectuate distributed mixing of a sample stabilizer within a blood sample and dispense the stabilized sample in a controlled manner. In this manner, a biological fluid collection device of the present disclosure enables blood micro-sample management, e.g., passive mixing with a sample stabilizer and controlled dispensing, for point-of-care and near patient testing applications.

Claims19

Dependent claims

A collection module adapted to receive a sample, the collection module comprising:

a housing having an inlet port and an outlet port, the inlet port and the outlet port in fluid communication;
a mixing chamber disposed between the inlet port and the outlet port;
a sample stabilizer disposed between the inlet port and the outlet port;
and
a collection chamber having a proximal end and distal end and disposed between the mixing chamber and the outlet port, wherein the collection chamber receives and contains the sample and at least a portion of the sample stabilizer therein;
and
a deformable portion transitionable between an initial position in which the sample is contained within the collection chamber and a deformed position in which a portion of the sample is expelled from the collection chamber,
wherein a diameter of the collection chamber tapers from a first diameter to a second diameter, and the first diameter is less than the second diameter.
