Reagent preparation and dispensing device
First Claim
1. An apparatus comprising:
- a body including;
a reaction chamber configured to include a reagent, anda solution reservoir configured to include a solution, the solution reservoir is isolated from the reaction chamber;
a dispensing path extending from the reaction chamber;
an activator movably coupled with the body, the activator includes a mixing configuration and a dispensing configuration, wherein;
in the mixing configuration, the activator is movable to mix the solution with the reagent in the reaction chamber, andin the dispensing configuration the activator is movable to dispense the solution through the dispensing path; and
a vent path different from the dispensing path extending from a reaction chamber, wherein the vent path vents the reaction chamber gas displaced by the addition of the solution to the reaction chamber throughout movement of the activator from the mixing configuration to the dispensing configuration.

Abstract
A reagent preparation and dispensing device includes a body having a reaction chamber for a reagent and a solution reservoir for a solution. The solution reservoir is isolated from the reaction chamber. A plunger is movably coupled with the body. Movement of the plunger from a starting position to a seated position pushes the solution into the reaction chamber. A dispensing path extends from the reaction chamber out of the body. The dispensing path is configured to dispense a reagent mixture formed from the solution and the reagent. A vent path extends from the reaction chamber, the vent path vents reaction chamber gas displaced by the addition of the solution to the reaction chamber throughout movement of the plunger from the starting position to the seated position.
