US 2019/0168214 A1 · DEVICES WITH MODIFIED CONDUITS

Abstract

A centrifugal rotor device includes a first chamber configured to hold a fluid, and a second chamber configured to receive the fluid from the first chamber. The centrifugal rotor device also includes a conduit coupled to the first chamber at a conduit inlet and coupled to the second chamber at a conduit outlet, the conduit configured to permit movement of the fluid from the first chamber to the second chamber. The conduit includes a first channel and a second channel formed adjacent to the first channel. The second channel is in fluid communication with the first channel and has a dimension smaller than the smallest dimension of the first channel. The conduit also includes one or more obstructive features present in the second channel configured to impede movement of the fluid in the second channel.

Dependent claims

A centrifugal rotor device, comprising:

a first chamber configured to hold a fluid;
a second chamber configured to receive the fluid from the first chamber;
and
a conduit coupled to the first chamber at a conduit inlet and coupled to the second chamber at a conduit outlet, the conduit configured to permit movement of the fluid from the first chamber to the second chamber, the conduit including:
a first channel;
a second channel formed adjacent to the first channel, the second channel in fluid communication with the first channel, the second channel having a dimension smaller than the smallest dimension of the first channel;

5 more elements

A centrifugal rotor device, comprising:

a rim defining a radially inward direction and a radially outward direction;
a first chamber configured to receive a set of fluids, the first chamber further configured to substantially mix the set of fluids to generate a mixed fluid during use, the first chamber including a side wall;
and
a conduit including a coupling portion coupled to the side wall of the first chamber at a conduit inlet, the conduit being in fluid communication with the first chamber, the coupling portion formed between the radially inward direction and a direction perpendicular to the radially inward direction at an angle of from about 0 degrees to about 180 degrees from the radially inward direction, the coupling portion disposed at a distance of from about 0.0250 mm to about 1 mm from a radially outward edge of the side wall.
