A flow restriction device may include a housing with first and second end portions forming respective first and second openings, and a cavity configured to receive an insert body defining a fluid passage that extends from a first opening of the housing at the first end portion to a second opening of the housing at the second end portion, where the fluid passage extends in more than one direction along a path between the first and second end portions of the housing to induce a resistance to a fluid flow moving through the device, thereby reducing a flow rate and pressure of the fluid, and where the fluid is blood, reduce the hemolysis index of the blood.

A housing for sample collection is disclosed. The housing comprises an actuating member configured to move between a first position and a second position, a sample collector and an assay component. In the first position the sample collector is in contact with the assay component and in the second position the sample collector is separated from the assay component and configured to collect a sample.
