Venturi Tip Enriched Medical Suspension Apparatus

The patent removes the impeller and fan components from the medical suspension delivery device, extracting the mixing function from the mechanical mixing system. Instead of using rotating blades to mix the sclerosant solution with tumescent fluid, the invention uses a Venturi effect-based flow mixing mechanism that eliminates complex mechanical mixing parts while achieving effective mixing through fluid dynamics principles.

The patent employs hydraulic principles through the Venturi effect to achieve mixing without mechanical components. The Venturi tube creates a pressure differential that draws the sclerosant solution and tumescent fluid together, using fluid pressure and flow dynamics to mix the components effectively. This hydraulic approach replaces the need for mechanical impellers and fans, simplifying the device while maintaining mixing effectiveness.

The catheter assembly serves multiple functions: it delivers the enriched medical suspension, creates the Venturi effect for mixing, and controls the flow of pressurized fluid. By integrating these functions into a single multi-functional device, the patent reduces the number of separate components needed, thereby simplifying manufacturing while maintaining effective delivery of the sclerosant solution.

The device uses the patient's own body as the source of tumescent fluid, eliminating the need for external fluid storage and delivery systems. The body's natural fluid provides the tumescent medium that mixes with the sclerosant solution through the Venturi effect, simplifying the device architecture by removing the need for complex external fluid management systems.

The patent uses the Venturi effect, a hydraulic phenomenon, to achieve effective mixing without complex mechanical mixing structures. The Venturi tube creates a pressure differential that automatically draws and mixes the sclerosant solution with tumescent fluid as they flow through the constriction. This hydraulic mixing mechanism provides effective mixing capability while maintaining a simple catheter structure that is easy to operate.

The patent changes the flow parameters of the medical fluids by creating a pressure differential through the Venturi effect. By controlling the pressure and flow rate of the pressurized fluid, the system achieves effective mixing of the sclerosant solution with tumescent fluid. This parameter-based mixing approach provides sufficient mixing capability without requiring complex mechanical mixing structures.
