APPARATUS, SYSTEM AND METHOD FOR MIXING AND DISPENSING DENTAL IMPRESSION MATERIALS

摘要

An apparatus, system and method for mixing and dispensing dental impression materials is described. A dental impression material mixing machine comprises a water dispenser fluidly coupled to a hollow mixing axle, the mixing axle extending through a pulley, wherein an inner circumference of the hollow mixing axle forms a water conduit and an outer circumference of the hollow mixing axle forms a hub connector, a closeable valve inserted at a water entrance to the water conduit and electronically coupled to a water pump, an electronically commutated motor rotateably coupled to the pulley, wherein the hub connector receives a tubular rotatable hub of a disposable mixing vessel comprising dry dental impression powder, and wherein water is dispensed from the water dispenser into the disposable mixing vessel through the water conduit and hub orifice.

1. A dental impression material mixing system comprising:
a mixing vessel comprising:
a flexible tubular wall; anda rounded bowl contiguous with the flexible tubular wall and forming a bottom of the mixing vessel, the rounded bowl having a slit at a base and comprising a removable adhesive sealedly enclosing the slit; a lid secured on the flexible tubular wall; a tubular rotatable hub fit into the lid; a flexible cord threaded through the tubular rotatable hub to form at least two loops of the flexible cord, the at least two loops extending from the tubular hub contouredly along an inner surface of the flexible tubular wall and rounded bowl, wherein the at least two loops cross each other at the base; and a mixing machine, the mixing machine comprising a rotatable hub connector and a water conduit; wherein the mixing vessel removeabley couples to the mixing machine, and wherein the mixing machine operates to dispense water into the mixing vessel and rotate the at least two loops of flexible cord such that dry dental impression material is hydrated and mixed to form a dental impression paste.
