PIVC-INTEGRATED HEMOLYSIS-REDUCTION ACCESSORIES WITH ANTI-SPILLAGE COMPONENT FOR DIRECT BLOOD DRAW

A flow restriction device may include a proximal housing including an internal fluid channel, a distal housing including an internal fluid channel, and an intermediate housing interposed between the proximal and distal housings. The intermediate housing may include an internal chamber, and a slider reciprocally disposed in the internal chamber. The slider may include an internal fluid channel and a seal overlaying an outer surface of slider excluding the fluid channel, and may be reciprocally movable between (i) a first position where the internal fluid channel of the slider is axially aligned with the internal fluid channels of the proximal and distal housings to allow a fluid to flow therethrough, and (ii) a second position where the internal fluid channel of the slider is not aligned with the internal fluid channels of the proximal and distal housings and the seal blocks fluid connection between the proximal and distal housings.
