The CSSD Disinfection and Supply Center of the Affiliated Dental Hospital of Anhui Medical University has fully implemented the Duwei Medical Clean Environment Control System. This system utilizes Duwei's patented intelligent micro-differential pressure transmission technology, precise micro-pressure measurement and control technology, and embedded software algorithms. Through PDCA full-process process control, it fundamentally addresses the pain points of isolated, static, one-sided data, and the inability to verify real-time effects. It establishes a gradient pressure difference and controls airflow groups, guiding airflow within the building to flow in a specified direction. It is suitable for important environmental control application scenarios such as outpatient and emergency wards, disinfection and supply centers, infectious disease control areas, and operating rooms.
The system adopts patented intelligent micro-differential pressure transmission technology, combined with a micro-pressure control unit, to collect pressure data in real-time, compute, and provide feedback to the air valve actuator for dynamic compensation. It precisely controls the air supply volume and air change rate, solves the pressure gradient control of each functional area in the three zones and two channels, realizes the control of air flow direction and dynamic compensation, utilizes information and intelligent means to enhance the intelligent operation and management level of "combining epidemic prevention and control with routine work" in general hospitals, accelerates the promotion of data sharing and business collaboration between hospital information and disease prevention and control institutions, and strengthens the construction of smart hospitals.
The pressure difference, temperature, and humidity monitoring system developed by Dewei Intelligence consists of intelligent differential pressure sensors, temperature and humidity sensors, data collectors, and corresponding connecting lines. It can be configured according to a modular structure for application in hospital intravenous infusion dispensing centers. The system has the advantages of simple structure, low cost, and convenient on-site installation and debugging. This monitoring system arranges and installs sensors based on the actual area, layout, and regulatory requirements of the room. The data collector not only achieves data collection but also has a display function. It enables accurate online real-time monitoring of data, and can also trigger an out-of-tolerance alarm based on pressure difference, temperature, and humidity indicators. Additionally, it can generate reports according to customer needs.
The outbreak of COVID-19 has brought immense distress to everyone. As the primary battlefield for treating patients and preventing the spread of the virus, hospitals must ensure environmental safety. It is particularly crucial for hospitals and medical staff to adopt proper early warning mechanisms to guarantee effective isolation in rooms.
General hospitals, while meeting the requirements of regular medical services, must also be capable of rapid transformation and conducting epidemic treatment during outbreaks. In accordance with the guidelines, Dewei Intelligence acted swiftly, organizing multiple departments for research and development, production, and testing, successfully developing an intelligent control system for the "combination of peacetime and epidemic" convertible wards in general hospitals.
A negative pressure ward refers to a ward that has been meticulously designed and is controlled by a purified air treatment system, creating a negative pressure within the ward that is lower than the pressure in other areas outside the ward. The air contaminated by patients in the ward is discharged to the outside through specialized pipelines after undergoing enhanced filtration treatment.
