Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an active water preparation system for medical dialysis. Background Technology

[0002] The activated water preparation system for medical dialysis is a device specifically designed for medical institutions to prepare water for hemodialysis and related treatments. Through a multi-stage purification process, raw water (such as tap water) is transformed into ultrapure water that meets medical standards. This water is used for dialysate preparation, dialyzer reuse, and concentrate preparation, ensuring a sterile, pyrogen-free, and impurity-free environment during dialysis, thus guaranteeing patient safety.

[0003] In existing activated water preparation systems for medical dialysis, the process typically involves activated carbon filtration followed by the addition of reagents for purification. Stirring is used to ensure uniform mixing of the reagents and water. However, current methods rely solely on stirring, resulting in uneven mixing, low treatment efficiency, and poor water quality stability. Therefore, we propose an activated water preparation system for medical dialysis to address this problem. Utility Model Content

This allows the stirring shaft and stirring blades to rotate on their own axis while revolving around the sun, resulting in a more uniform mixing of the raw water and reagents. This leads to higher processing efficiency and better water quality stability. After mixing, the water is discharged through a discharge pipe to a collection tank via a second control valve.

In this utility model, the activated water preparation system for medical dialysis allows for the upward pulling of the first and second insertion rods, disengaging them from the interior of the first and second filter boxes respectively. This removes restrictions on the movement of the first and second filter boxes. Then, by pulling the first and second pull plates, the first filter box and activated carbon adsorption layer can be easily detached from the feed box and collection box, facilitating cleaning of the first and second filter boxes and replacing the activated carbon adsorption layer inside the first filter box. This utility model has a reasonable structural design. Through the cooperation between the servo motor, rotating shaft, rotating cylinder, gear ring, gear, stirring shaft and stirring blade, the stirring shaft and stirring blade can achieve rotation when they revolve around the sun. This makes the mixing of raw water and reagents more uniform, resulting in higher treatment efficiency and better water quality stability. Attached Figure Description
