A static mixer for liquids or gases includes a housing having a continuous inner surface defining a fluid flow path for liquids or gases, an inlet to the fluid flow path, and an outlet from the fluid flow path, and an insert extending longitudinally through the fluid flow path between the inlet and the outlet. The insert is elastically expansive to exert outwardly directed pressure against the continuous inner surface of the housing. In one embodiment, the insert is hollow and has deflectors dispersed therethroughout and each projecting inwardly into the fluid flow path. In another embodiment, the insert includes a helical deflector extending inwardly into the fluid flow path from the continuous inner surface, and helically about a longitudinal axis of the housing.

An actuating mechanism for a dual pump dispensing system comprises an actuator housing, a semi-spiral insert and optionally, a mesh screen (3). The actuating mechanism is intended to mix viscous products that flow under the forces achieved in mechanical pump dispensers of the types used in the cosmetic and personal care fields.

A system for dispensing a biocompatible reactive formulation includes a first chamber containing a first fluid having a first reactive component, a second chamber containing a second fluid having a second reactive component, and a third chamber containing a third fluid.
