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.
Claims16
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 disposed between the mixing chamber and the outlet port, the collection chamber including a first deformable portion and a second deformable portion, wherein the mixing chamber receives the sample and at least a portion of the sample stabilizer therein,
- wherein the first deformable portion and the second deformable portion are 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.
A biological fluid collection device, 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 disposed between the mixing chamber and the outlet port, the collection chamber including a first deformable portion and a second deformable portion, wherein the mixing chamber receives the sample and at least a portion of the sample stabilizer therein,
- wherein the first deformable portion and the second deformable portion are 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;
- and
- an outer housing removably connectable to the collection module,
- wherein, with the collection module connected to the outer housing, the collection module is disposed within the outer housing.
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;
- a collection chamber disposed between the mixing chamber and the outlet port, the collection chamber including a first deformable portion and a second deformable portion, wherein the mixing chamber receives the sample and at least a portion of the sample stabilizer therein;
- a material including pores disposed between the inlet port and the mixing chamber;
- a dry anticoagulant powder within the pores of the material;
- and
- a cap covering the outlet port and having a venting plug which allows air to pass therethrough and prevents the sample from passing therethrough.
