Product Introduction

Dewey Intelligence (New Third Board 839901) relies on the Dewey Micro Pressure Intelligent Measurement and Control Engineering Collaborative Research and Development Center, combined with 24 years of practical experience in online monitoring of pharmaceutical industry cleanrooms, and has successfully developed a hospital ward positive and negative pressure intelligent conversion control system for epidemic prevention and control. The system adopts intelligent micro differential pressure transmission patent, precise micro pressure measurement control technology and embedded software algorithm. Guided by goals and results, and through the whole process management and control of PDCA, it fundamentally solves the problem of isolated, static, one-sided, qualitative and quantitative data of technical prevention control points, which cannot be verified in real time, as well as the pain points that can not be measured or controlled in the last kilometer of hospital prevention and control. It establishes gradient pressure difference, controls the air flow organization WYSIWYG, guides the flow of virus containing aerosols such as COVID-19 in the specified direction, and blocks the path of virus transmission with one key switching.

Product performance

One click switch for epidemic prevention and control

One click zero delay switch to negative pressure mode, meeting the requirements of the "Technical Guidelines for Building Convertible Wards in Comprehensive Hospitals with 'Combination of Epidemic Prevention and Control' (Trial)" (hereinafter referred to as the "Guidelines") 2.1 for rapid conversion and epidemic treatment during epidemics.

Gradient pressure control

Dewey high-precision differential pressure transmitters are deployed at the entrance of negative pressure wards and buffer rooms to measure and adjust the set pressure difference in real time. During the epidemic, the pressure difference is guaranteed to be -5Pa-10Pa, meeting the requirements of 6.1.6 and 6.3.5 of the "Guidelines". During the epidemic, the ventilation system should control the air pressure gradient in each area, so that the air flows unidirectionally from the clean area to the semi polluted area and polluted area.

Airtight feedback and verification

To solve the qualitative and quantitative key problems caused by manual inspection, visual inspection, and smoke emission methods in the current negative pressure ward gradient pressure difference and airflow control acceptance process, and to verify the results, what you see is what you get.

Environmental parameter monitoring

Deploy Dewey multifunctional environmental monitoring device to monitor indoor temperature and humidity CO2， Monitor the concentration, PM2.5 concentration, VOC, etc. to meet the environmental monitoring requirements of 7.2.8 of the Guidelines.

Ventilation rate monitoring

Dewey ventilation air volume sensors are deployed at the air supply outlet, and the measured values are displayed in real-time on the door machine screen, meeting the requirements of 6.1.7 and 6.3.2 of the Guidelines for fresh air ventilation during epidemics.

Filter status monitoring

Dewey high-precision micro differential pressure transmitters are deployed in the air filter section of the supply and exhaust system, the intermediate efficiency filter of the air conditioner, and the high-efficiency filter section of the room exhaust outlet for pressure difference detection and alarm, meeting the requirements of 6.1.8 and 6.1.10 of the Guidelines for pressure difference detection and alarm of the supply and exhaust outlet filters.

Alarm Settings

Five types of abnormal alarms, prompting alarms on the display screen of the door machine and the nurse station screen.

● Equipment malfunction alarm

● Alarm for abnormal environmental indicators

● Differential pressure alarm for filters at all levels

● Abnormal door magnetic status alarm

● Alarm for insufficient ventilation rate

Product advantages

The hospital infection prevention and control exclusive platform reserves dedicated communication interfaces to provide effective data support for the smart hospital platform, fully utilizes information and intelligent means, improves the level of intelligent operation and management of hospitals, builds a hospital medical Internet of Things, organically connects the massive medical equipment and non-medical assets of hospitals, realizes medical equipment status monitoring, hospital asset management, in-hospital emergency dispatch, medical staff management, access control and security services, improves hospital management efficiency and patient medical experience, accelerates the sharing of hospital information and disease prevention and control institution data, business collaboration, and strengthens the construction of smart hospitals.

According to the needs of epidemic treatment, the "integration of epidemic prevention and control" convertible ward intelligent hospital infection prevention and control platform will be connected with management department platforms such as the Centers for Disease Control and Prevention and the Emergency Command Center for unified management. Based on the principle of "integration of epidemic prevention and control, hierarchical classification, and efficient cooperation", a hierarchical and differentiated urban infectious disease treatment network will be constructed.
