US 2024/0286809 A1 · METHOD AND APPARATUS FOR PREPARING A LIQUID PREPARATION

Abstract

An apparatus is disclosed for preparing a liquid preparation using a two-part system comprising a first part including a first reagent and a second part including a second reagent, wherein the first reagent and the second reagent react when mixed to form an active ingredient of the liquid preparation. The apparatus comprising a mixing funnel having a reaction chamber, an inlet region for admitting a quantity of the first part and a quantity of the second part into the reaction chamber, for example from a dispensing capsule, to form a reagent mixture in the reaction chamber in use, and an outlet comprising at least one restriction orifice for releasing the reagent mixture from the reaction chamber at a controlled rate, and a primary chamber arranged to receive the reagent mixture from the reaction chamber through the restriction orifice.

Dependent claims

An apparatus for preparing a liquid preparation according to the method of claim 18,

the apparatus comprising:
a mixing funnel having a reaction chamber, an inlet region for admitting a quantity of the first part and a quantity of the second part into the reaction chamber to form a reagent mixture in the reaction chamber in use, and an outlet comprising at least one restriction orifice for releasing the reagent mixture from the reaction chamber at a controlled rate;
and
a primary chamber arranged to receive the reagent mixture from the reaction chamber through the restriction orifice;
wherein the or each restriction orifice is disposed in a base part of the mixing funnel and provides a permanently open flow path from the reaction chamber to the primary chamber, and the reagent mixture flows through the restriction orifice under gravity.
