AI Technical Summary

Technical Problem

Existing dialysis fluid preparation equipment suffers from noisy stirring structures, low stirring efficiency, and is prone to damage, failing to meet the needs of the medical environment.

Method used

The liquid stirring structure adopts a power pump assembly. The water inlet of the power pump assembly is located at the top of the liquid mixing tank, and the water outlet is connected to the nozzle through a shaft tube. The nozzle is bent inward to spray low-concentration liquid to mix with high-concentration liquid, avoiding contact between high-concentration solute and pump assembly. Multiple micro pumps are connected in parallel to reduce power requirements.

Benefits of technology

It effectively reduces noise, extends equipment life, lowers maintenance costs, improves mixing efficiency, and meets the needs of medical environments.
