Mixing devices (100) used with a syringe or syringe system (150) and related systems for homogenously mixing two part compositions, as well as single part compositions which include components that may tend to separate over time (e.g., a fluoride varnish composition). The devices (100) and systems (150) include a hollow elongate handle (104) having a proximal end (106), a distal delivery end (108), and a delivery passageway therethrough. A mixing member (110) is disposed at or near the proximal end (106) of the hollow elongate handle (104), which mixing member and a portion of the handle are axially slidable within a syringe barrel (120) during use. The user may push and pull the distal end (108) of the handle (104), causing corresponding axial movement of the mixing member (110) within the syringe barrel (120). |
