AI Technical Summary

Technical Problem

Existing methods for cleaning and disinfecting dental chair water systems lack dynamic adaptation to branch pipeline parameters, have insufficient compatibility between disinfection ratios and valve openings, lack real-time control of pressure and water quality, result in uneven cleaning effects, and make it impossible to accurately determine residues, posing a risk of cross-infection.

Method used

By collecting and analyzing the effective ingredient content and storage volume of enzyme detergents and disinfectants, as well as liquid level data, and combining this with flow rate, pressure, and water quality data, cleaning and disinfection parameters are dynamically adjusted to achieve fully automated and precise control of the entire process, ensuring uniform disinfection and no residue.

Benefits of technology

It enables targeted pre-cleaning of each branch pipeline, ensuring uniform and thorough disinfection, reducing manual intervention, lowering the risk of cross-infection, and guaranteeing the hygiene and safety of the dental chair's water system.

Abstract

The present application relates to the technical field of dental chair waterway disinfection, and discloses an intelligent circulating cleaning and disinfection method and system for a multi-branch dental chair waterway, which comprises the following steps: starting main waterway flushing, collecting enzyme detergent, effective components of disinfectant, storage capacity and liquid level data, and determining the proportioning of enzyme detergent and disinfectant and valve opening degree; triggering a cleaning mode according to the flow data and flow threshold value of each branch of the dental chair, conveying enzyme washing liquid to enter a disinfection mode after the water quality reaches the standard, dynamically adjusting pressure to convey disinfectant for disinfection, switching branches in a preset order to complete the whole process, and finally venting and emptying to be free of residues. Through multi-module cooperation, real-time data collection, dynamic parameter adaptation, accurate pressure adjustment and orderly path switching, the present application realizes efficient cleaning and disinfection of the multi-branch waterway and residue control, and guarantees the safety of diagnosis and treatment.
