Introduction to the Liquid Preparation System

Centralized hemodialysis‑concentrate supply systems are applied in medical‑institutions, especially medium‑ and large‑scale hospitals. The system is classified for A‑concentrate and B‑concentrate. A‑concentrate and B‑concentrate will be blended at a ratio of 1:1 before delivery to hemodialysis machines for patient treatment. The A‑concentrate is prepared with an aqueous solution containing sodium chloride, potassium chloride, calcium chloride, magnesium chloride and acetic acid. The B‑concentrate is mainly formulated with sodium‑bicarbonate aqueous solution, or the mixture of sodium bicarbonate and sodium‑chloride.

Process Description

The A‑concentrate and B‑concentrate are prepared by two separate dispensing units with identical configurations, matching the 1:1 mixing‑proportion for two‑type concentrates. Each dispensing system includes a preparation tank, a storage tank, sanitary transfer pumps, microporous‑membrane filters and pipeline distribution assemblies.

Safety Performance

Traditional manual‑preparation modes for hemodialysis‑concentrate may raise the possibility of pollutants and microbial contamination risks. Tongxie designs this system following GMP standards for pharmaceutical‑manufacturing workshops and selects smooth‑surfaced 316L stainless‑steel as the wetted‑part material. The whole preparation system supports convenient cleaning and disinfection operations. A built‑in self‑circulating hot‑water system provides thermal disinfection, and chemical disinfectants can also be adopted for routine disinfection works.

Development Prospect

Centralized and automatic delivery for hemodialysis A‑concentrate and B‑concentrate helps shorten manual‑operation hours, lower hygiene‑related risks and improve the overall service level of medical‑institutions, bringing benefits to numerous patients. This system will gain growing popularity in practical projects.
