Abstract
Flow restricting adapters may include a first and second connector portions, to permit coupling of the adapter restricting flow between a catheter and blood collection device, and a post forming an inner lumen for directing blood through the flow restricting device, the post having a length configured to extend through the first connector portion and be positioned within a portion of the blood collection device, such as the needle of a blood collection tube holder, when the flow restricting device is coupled with the blood collection device, the post having an inner lumen to increase flow resistance and reduce shear stress of blood moving through the flow restricting device, thereby decreasing the incidence of hemolysis.
Claims20
A flow restriction adapter for restricting hemolysis, the flow restriction adapter comprising:
- a first connector portion forming a female luer having a first cavity;
- a second connector portion forming a male luer having a second cavity;
- a post comprising a proximal end positioned between the male luer and the female luer, a middle portion extending through the first cavity, a distal end positioned distally to the female luer, and an inner lumen extending from the second cavity through the distal end of the post.
A flow restriction adapter for restricting hemolysis, the flow restriction adapter comprising:
- a first connector portion comprising a first connector end, an inner surface, and a first cavity floor, wherein the inner surface and the first cavity floor form a first cavity;
- a second connector portion comprising a second connector end and an inner surface forming a second cavity;
- and
- a post comprising a proximal end at the first cavity floor, a middle portion extending through the first cavity, a distal end positioned distally to the first connector end, and an inner lumen extending from the second cavity through the distal end of the post.
