Construction of Clean Engineering for Hemodialysis Centers
2024.11.22
In the field of medical and health care, hemodialysis centers play an extremely crucial role, providing indispensable treatment services for numerous patients with renal failure to prolong their lives and improve their quality of life. Guangzhou Kunling Purification Equipment Co., Ltd. has been always committed to contributing to medical purification projects. Today, we will have an in-depth discussion on the key points and significance of the construction of clean engineering for hemodialysis centers.
I. Special Requirements of Hemodialysis Centers
Patients undergoing hemodialysis generally have relatively low immunity and are highly susceptible to infections. Therefore, a clean, sterile environment with appropriate temperature and humidity has a decisive impact on their treatment safety and rehabilitation outcomes. Unlike ordinary medical places, hemodialysis centers have more stringent requirements for air quality, water purification, and the overall cleanliness of the space.
II. Spatial Layout and Zoning Planning
A reasonable spatial layout is the foundation for the construction of clean engineering in hemodialysis centers.
· Clear Functional Zoning: Strictly divide the clean area, contaminated area, and semi-contaminated area. The hemodialysis treatment area, as the core area, must be kept highly clean and equipped with an advanced air purification system to ensure continuous circulation and filtration of air and reduce the number of microorganisms and dust particles. The preparation area, fluid dispensing area, etc. should be effectively separated from the treatment area to avoid cross-contamination. The contaminated area, such as the temporary storage area for medical waste, should have an independent passage and complete protective facilities to prevent the spread of pollutants.
· Design of Patient and Medical Staff Circulation Routes: Plan dedicated passages for patients and medical staff to achieve separate entry and exit. The route for patients from the waiting area to the treatment area should be simple and smooth, reducing unnecessary stops and intersections. The passage for medical staff should facilitate their quick access to various work areas, and buffer zones should be set up at the junctions of different areas for changing protective equipment.
III. The Key Role of the Air Purification System
· Selection of High-Efficiency Filters: The use of High-Efficiency Particulate Air (HEPA) filters can effectively filter out tiny particles in the air, including pathogens such as bacteria and viruses, which is crucial for ensuring the air quality in the hemodialysis center. According to the cleanliness requirements of different areas, select appropriate grades of filters. For example, in the hemodialysis treatment area, H13 or higher-level HEPA filters can be selected to ensure that the number of dust particles and the content of microorganisms in the air are controlled at an extremely low level.
· Fresh Air System and Ventilation Frequency: Reasonably design the fresh air system to ensure an adequate supply of fresh air and dilute the concentration of indoor pollutants. Generally speaking, the ventilation frequency in the hemodialysis center should be higher than that in ordinary medical places, reaching 12 - 15 times per hour or even higher. The fresh air system should also have the function of adjusting temperature and humidity to maintain a comfortable and stable indoor environment and avoid causing patient discomfort or equipment failure due to inappropriate temperature and humidity.
IV. The Water Purification Treatment Process
During the hemodialysis process, patients' blood is in direct contact with a large amount of dialysis water, so the quality of water purification is directly related to patients' lives.
· Multi-level Water Purification Technology: Adopt advanced reverse osmosis (RO) technology as the core, combined with ultrafiltration, ion exchange and other processes to remove various impurities, microorganisms, endotoxins, heavy metal ions and other harmful substances in the water. From the entry of raw water to the production of pure water that meets the dialysis standards, it must go through multiple strict purification processes. Moreover, strict monitoring points should be set up in the entire water purification system to monitor the changes in water quality in real time and ensure that the water quality always complies with relevant national standards and dialysis treatment requirements.
· Maintenance and Disinfection of the Water Purification System: Regularly maintain and service the water purification equipment, including replacing filter cartridges, cleaning key components such as reverse osmosis membranes. At the same time, establish a complete water system disinfection system, which can combine chemical disinfection and thermal disinfection methods to regularly conduct comprehensive disinfection on the entire water purification pipeline and water storage containers to prevent the growth of microorganisms and the formation of biofilms.
V. Selection of Decoration Materials
· Preference for Environmentally Friendly and Antibacterial Materials: In the selection of decoration materials for walls, floors, and ceilings, environmentally friendly, antibacterial, easy-to-clean, and seamless materials should be chosen. For example, antibacterial medical wall panels can be used for walls, and seamless antibacterial rubber floors can be used for floors. These materials can not only effectively inhibit the growth and reproduction of bacteria but also facilitate daily cleaning and disinfection and reduce the hiding places for dust and microorganisms.
· Design to Avoid Dust Accumulation and Bacteria Growth: In terms of decoration details, sharp corners and gaps should be avoided to prevent dust accumulation. The installation of lighting fixtures, ventilation openings and other equipment should also focus on sealing treatment to prevent air leakage and dust entry and ensure the integrity of the cleanliness of the entire space.
VI. Supporting and Maintenance of Equipment and Facilities
· Layout of Hemodialysis Equipment and Maintenance Space: Reasonably arrange the layout of hemodialysis equipment in the treatment area, ensuring both the convenience and comfort of patients during treatment and sufficient space for equipment maintenance and repair. Each hemodialysis equipment should be equipped with complete water and electricity interfaces, drainage pipes, and waste liquid collection devices around it, and these facilities should be regularly inspected and maintained to ensure normal operation.
· Improvement of Other Auxiliary Facilities: Hemodialysis centers should also be equipped with complete auxiliary facilities, such as an emergency power supply system to cope with sudden power outages and ensure the continuity of hemodialysis treatment; a medical gas supply system to ensure the stable supply of oxygen and other gases; and a complete medical waste disposal facility to safely and standardly handle the large amount of medical waste generated during the hemodialysis process.
The construction of clean engineering for hemodialysis centers is a complex and systematic project, involving multiple aspects such as spatial layout, air and water purification, material selection, and the matching of equipment and facilities. Guangzhou Kunling Purification Equipment Co., Ltd., with its professional technology and rich experience, can provide comprehensive and high-quality construction plans and services for clean engineering in hemodialysis centers, creating a safe, comfortable, and clean dialysis treatment environment for patients with renal failure and contributing to the development of the medical and health care cause.
