In infection control, a proper and well-structured design is the foundation for the safe operation of the entire sterilization system within a hospital. Understanding this, Duong Gia does not simply execute based on requests—we accompany hospitals from the very first step to jointly develop an effective, optimized, and sustainable Central Sterile Services Department (CSSD).
Understanding and Analyzing Real Needs – The Foundation of Every Solution
Each hospital differs in scale, building structure, instrument flow, and usage frequency. Therefore, every design must begin with a thorough on-site assessment:
-
- Direct observation of the movement of medical instruments from various departments (Surgery – ICU – Endoscopy) to the CSSD.
-
- Evaluation of existing infrastructure: facilities, utilities, water systems, compressed air, steam, and electrical supply.
-
- Identification of operational bottlenecks to propose specific improvements.
-
- Only by understanding what the hospital truly needs can the proposed solution deliver real, practical value.

Solution Design Consulting
Duong Gia’s engineering team combines medical equipment expertise, infection control standards, and real hospital operational experience to:
-
- Plan the CSSD layout following the unidirectional workflow principle, clearly separating the three core areas: dirty receiving & decontamination – cleaning – sterilization.
-
- Propose the most suitable equipment configuration aligned with processing capacity and budget.
-
- Advise on technical details—door sizes, electrical outlet positions, steam piping, floor slope, regenerated water flow, and more—small factors that directly affect safety and equipment lifespan.
2D–3D Design: Visualizing the Solution
Based on the survey findings and consulting process, Duong Gia develops detailed 2D drawings illustrating the floor layout, technical infrastructure, workflow direction, and equipment connections.

Following this, a 3D model is developed to help the hospital visualize the entire operational space before entering the construction phase.
