Dental Evacuator Adapter with Vortex Impeller for Aerosol Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental evacuation systems face challenges in providing adequate suction power during procedures, especially when multiple devices are used simultaneously, leading to reduced vacuum power and potential leakage of contaminated aerosols, which increases the risk of infectious agent transmission.
Innovation Solution
A suction adapter system that enhances the suction power of evacuators by incorporating a suction assembly with a venturi tube, impeller mechanism, and a suction connector, designed to increase airflow rate and effectively capture aerosols and spatters, featuring a venturi tube, shark fin tube, and triple helix tube configurations to create a vortex and break down particles, and a suction connector with a funnel-shaped collector to capture aerosols and spatters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple evacuators are used simultaneously during dental procedures, then the capacity to handle aerosols and fluids increases, but the suction power of each individual evacuator is reduced
Solution Approach 1:
The patent combines multiple evacuators into a single integrated adapter system that connects to one evacuator. The adapter includes multiple inlet ports that can simultaneously receive aerosols and fluids from different sources, merging their flow paths while maintaining the full suction power of a single evacuator. This resolves the contradiction by achieving multi-source capture capacity without dividing the suction power among multiple devices.
2Object-affected harmful factors
If standard evacuators are used during dental procedures, then basic suction function is provided, but aerosols and contaminated fluids can leak and increase infection risk
Solution Approach 1:
The adapter acts as an intermediary device between the patient's mouth and the evacuator. It includes sealed connections and a structured flow path that reliably directs aerosols and fluids into the evacuator while preventing leaks. The adapter's design with proper sealing mechanisms and flow control ensures that contaminated materials are fully captured and directed to the vacuum source, eliminating the reliability issues of standard evacuators and reducing infection risk.
3Object-affected harmful factors
If complex adapter systems with multiple components are used to increase suction power, then aerosol capture effectiveness improves, but device complexity and ease of cleaning decrease
Solution Approach 1:
The adapter is designed as a segmented system with removable components, including detachable inlet ports and a separable body. This segmentation allows individual components to be easily removed for cleaning and disinfection without requiring disassembly of the entire system. Each segment can be independently cleaned, maintaining high aerosol capture effectiveness while significantly improving ease of cleaning compared to integrated complex systems.

AI summary
An adapter for an evacuator for increasing a suction power of the evacuator includes a suction assembly adapted to be coupled with the evacuator. The suction assembly has a housing, an impeller arranged inside the housing and configured to provide a suction, and an inlet conduit to facilitate a flow of fluid to the impeller. The suction assembly also includes an outlet conduit arranged inside the housing and adapted to be coupled to the evacuator. The outlet conduit is in fluid communication with the impeller and facilitates a flow of the fluid from the suction assembly to the evacuator.
