Abstract
In one embodiment described herein, a bodily fluid separation material is provided comprising a formed component capture region and a bodily fluid pass-through region. The pass-through region has structures with a reduced liquid leaching quality relative to than the capture region, wherein during separation material use, bodily fluid enters the capture region prior to entering the pass-through region. Optionally, a bodily fluid pass-through region has a reduced amount of liquid leaching material relative to than the capture region.
Claims15
A bodily fluid separation material comprising:
- a first capture region formed of a first material and having an anti-hemolytic surface coating not comprising the first material;
- a second capture region formed of the first material and without the anti-hemolytic surface coating not comprising the first material;
- and
- a bodily fluid pass-through region formed of the first material and comprising pass-through openings sized so that formed components of the bodily fluid do not enter the bodily fluid pass-through region.
A bodily fluid separation material comprising:
- a first capture region formed of a first material and having an anti-hemolytic surface coating not comprising the first material;
- a second capture region formed of the first material and without the anti-hemolytic surface coating not comprising the first material;
- and
- a bodily fluid pass-through region formed of the first material and comprising pass-through openings sized so that formed components of the bodily fluid do not enter the bodily fluid pass-through region;
- wherein the first capture region defines a first filter region of the separation material having an anti-hemolytic coating and pore spacing sized to constrain formed blood components therein;
- wherein the bodily fluid pass-through region defines a second filter region of the separation material having pore spacing smaller than pore spacing of the first filter region with pores sized so that formed components do not enter the second filter region and configured to have an amount of anti-hemolytic coating less than that of the first region.
A bodily fluid separation material comprising:
- a first capture region formed of a first material and having an anti-hemolytic surface coating not comprising the first material;
- a second capture region formed of the first material and without the anti-hemolytic surface coating not comprising the first material;
- and
- a bodily fluid pass-through region formed of the first material and comprising pass-through openings sized so that formed components of the bodily fluid do not enter the bodily fluid pass-through region;
- wherein the first capture region, second capture region, and the bodily fluid pass-through region comprise a percolating network.
