Abstract
Described is an automated reagent dispensing cap and methods of use in an automated clinical analyzer for introducing one or more reagent components housed in the reagent dispensing cap into a container enclosing another reagent component with which it is combined to achieve a reagent useful for diagnostic testing.
Claims17
A device for storing reagents, comprising:
- a reagent dispensing cap 10,
- said reagent dispensing cap 10 comprising,
- a housing 12 with a central axially disposed lumen 11, said housing comprising a slider 9 configured to move laterally in the housing 12 in a direction that is perpendicular to the lumen 11 of the housing 12;
- wherein said slider 9 comprises one or more through-holes 5 configured to house a reagent component, each of said one or more through-holes 5 comprising an open end, a first position, and a second position, said through-hole aligned with the lumen 11 of the housing 12 in said second position, wherein said alignment is configured to release the reagent component housed in said through-hole 5 via said through-hole open end.
1 more element
A method for preparing reagent components for mixing together in an automated clinical analyzer, the method comprising:
- storing one or more reagents in a reagent chamber within a container lid;
- forming a gas-tight seal between a first opening of the lumen and the reagent chamber by positioning a threaded cylindrical member within a lumen of the container lid such that the cylindrical member is operatively engaged with internal threads of the lumen;
- moving the cylindrical member along a longitudinal axis of the container lid;
- positioning a breakable seal at a second end of the lumen to seal the second end of the lumen such that the reagent chamber is bounded in the lumen between the cylindrical member and the breakable seal;
- joining or forming an attachment structure to the second end of the lumen wherein the attachment structure includes an engagement portion shaped for receiving a mating engagement portion of the container at an opening of the container;
- sealing the opening of the container by retaining the lumen and the breakable seal in a fixed position against the container at an opening of the container.
3 more elements
A method for storing reagents, comprising:
- providing a reagent dispensing cap 10,
- providing a housing 12 of the reagent dispensing cap with a central axially disposed lumen 11, said housing comprising a slider 9 configured to move laterally in the housing 12 in a direction that is perpendicular to the lumen 11 of the housing 12.
- said slider 9 comprising one or more through-holes 5 configured to house a reagent component, each of said one or more through-holes 5 comprising an open end, a first position, and a second position, said through-hole aligned with the lumen 11 of the housing 12 in said second position, wherein said alignment is configured to release the reagent component housed in said through-hole 5 via said through-hole open end.
