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.
Claims11
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 mixing chamber;
- and
- a collection chamber disposed between the mixing chamber and the outlet port for receiving the sample therein, and
- a one-way valve configured to permit the movement of air into the collection chamber to expel the sample therefrom,
- wherein the collection chamber comprises:
- a rigid wall chamber that receives the sample and has a constant internal diameter between the one-way valve and the outlet port, wherein the internal diameter is defined by the rigid wall chamber .
