Abstract
A device for obtaining a biological sample, such as a capillary blood collection device, that has the ability to lance and squeeze the finger, collect the sample, stabilize the sample, and subsequently dispense the sample in a controlled manner is disclosed. The device also simplifies and streamlines the capillary blood collection by eliminating workflow variabilities which are typically associated with low sample quality including hemolysis and micro-clots.
Claims29
A device for obtaining a blood sample, the device comprising:
- a holder for receiving a sample source, the holder having an actuation portion and a port;
- a lancet housing secured within the port, the lancet housing having an inlet and an interior;
- a puncturing element moveable between a pre-actuated position wherein the puncturing element is retained within the interior and a puncturing position wherein at least a portion of the puncturing element extends through the inlet;
- and
- a container removably connectable to a portion of the lancet housing, the container defining a collection cavity,
- wherein the actuation portion is configured to be transitioned by a user between a first position in which the holder defines a first elliptical shape and a second position in which the holder defines a second elliptical shape, and
- wherein the second elliptical shape is smaller than the first elliptical shape in at least one direction.
A device for obtaining a blood sample, the device comprising:
- a holder for receiving a sample source, the holder having an actuation portion and a port, wherein the actuation portion includes a pumping member for applying pressure to the sample source,
- wherein the actuation portion is transitionable by a user between a first position in which the holder defines a first elliptical shape and a second position in which the holder defines a second elliptical shape, wherein the second elliptical shape is smaller than the first elliptical shape in at least one direction.
