Abstract: A diagnostic test device to perform a test on a biological or environmental sample is provided. In one aspect, the diagnostic test device includes a sample preparation reservoir; a dispensing mechanism that includes a sealing member and a piercing member; and at least one diagnostic test reservoir separated from the sample preparation reservoir by a seal. A predetermined volume of fluid is defined between the sealing member, the piercing member, sides of at least one chamber defined by the sample preparation reservoir, and the seal when the sealing member engages the sides of the at least one chamber. The piercing member disrupts the at least one seal to dispense the predetermined volume of fluid to the at least one diagnostic test reservoir. The sealing member is configured to directly contact the sides of the at least one chamber as the seal is disrupted.

Abstract: A flow regulator for a blood collection assembly includes a housing having an inlet and an outlet, which defines an interior space between the inlet and the outlet. A membrane having a first surface and a second surface is disposed at least partially within the interior space. The membrane has a first position where a flow path between the inlet and the outlet is substantially open, and a second position where the flow path between the inlet and the outlet is at least partially restricted. The membrane is configured to move between the first and second positions in response to a pressure differential acting on the membrane.

Abstract: A valve actuator that moves in a catheter assembly between a first position where a valve is closed and a second position where the valve is open, the valve actuator including a shaft portion at a distal end of the valve actuator that is configured to pierce the valve, a mating portion at a proximal end of the valve actuator that is configured to engage a Luer device, a diameter reduction region that connects the shaft portion and the mating portion, and a plurality of windows that extend through the valve actuator for flushing fluid, the plurality of windows being disposed in the diameter reduction region, wherein each of the plurality of windows does not extend a full length of the diameter reduction region.
