Abstract
A biological fluid collection device that includes a housing and a cartridge that is removably receivable within a portion of the housing is disclosed. The biological fluid collection device of the present disclosure allows for collection of capillary blood from a finger stick and provides a closed system that reduces the exposure of a blood sample. In one embodiment, a cartridge of the present disclosure also provides fast mixing of a blood sample with a sample stabilizer. In another embodiment, a cartridge of the present disclosure provides automatic plasma separation of the blood sample. Advantageously, once the cartridge is filled with a sample aid removed from the housing, the cartridge can be used for a variety of important purposes.
Claims22
A biological fluid collection device, comprising:
- a housing having an upper portion, a side portion, and a bottom portion, the upper portion having an inlet port and defining a cartridge receiving cavity, wherein the upper portion, the side portion, and the bottom portion of the housing together define a c-shaped cavity configured to receive a patient's finger therein;
- a puncturing element moveable between a pre-actuated position wherein the puncturing element is retained within a portion of the upper portion of the housing and a puncturing position wherein the puncturing element extends through the inlet port and provides fluid communication with a portion of the cartridge receiving cavity;
- a button arranged on the upper portion of the housing and coupled with the puncturing element;
- and
- a cartridge having a reservoir and an inlet, the cartridge removably receivable within the cartridge receiving cavity of the housing, the inlet of the cartridge configured to be pierced by the puncturing element,
- wherein the cartridge is adapted to receive a blood sample therein while the puncturing element is in the puncturing position,
- wherein, with the cartridge received within the cartridge receiving cavity, the inlet port is in fluid communication with a portion of the reservoir of the cartridge, and
- wherein the cartridge receiving cavity is arranged between the button and the c-shaped cavity.
A biological fluid collection and testing system, comprising:
- a biological fluid collection device, comprising:
- a housing having an upper portion, a side portion, and a bottom portion, the upper portion having an inlet port and a cartridge receiving cavity and wherein the upper portion, the side portion, and the bottom portion of the housing together define a c-shaped cavity configured to receive a patient's finger therein;
- a puncturing element moveable between a pre-actuated position wherein the puncturing element is retained within a portion of the upper portion of the housing and a puncturing position wherein the puncturing element extends through the inlet port and provides fluid communication with a portion of the cartridge receiving cavity;
- a button arranged on the upper portion of the housing and coupled with the puncturing element;
- and
- a cartridge having a reservoir and an inlet, the inlet of the cartridge configured to be pierced by the puncturing element, and the cartridge removably receivable within the cartridge receiving cavity of the housing, the cartridge adapted to receive a blood sample therein while the puncturing element is in the puncturing position,
- wherein, with the cartridge received within the cartridge receiving cavity, the inlet port is in fluid communication with a portion of the reservoir of the cartridge,
- wherein the cartridge receiving cavity is arranged between the button and the c-shaped cavity;
- and
- a near patient testing station having a receiving portion, wherein the cartridge is removably receivable within the receiving portion.
