In recent days, Cai Xiujun, a member of the National Committee of the Chinese People's Political Consultative Conference and president of the Shaw Hospital affiliated to the School of Medicine of Zhejiang University (Shaw Hospital of Zhejiang University), has a somewhat full schedule. Xinjiang, Hainan, Zhejiang... He visited and researched all over the country, promoted the "combination of anti-epidemic treatment" to quickly switch the ward mode, improved the proposal, and opened his two sessions in advance. As the "leader" of a hospital, Cai Xiujun has always been tight on the prevention and control of the COVID-19 in the past three years. In the front line of epidemic prevention and control, he was well aware that there were obvious shortcomings in the construction of infectious disease wards in China: when a major epidemic occurred, the traditional infectious disease hospital wards were limited and could not meet the social needs, while the building layout of most general hospitals did not have the ability to treat patients with respiratory tract infectious diseases. In 2020, Cai Xiujun visited Shanghai, Jiangsu and Zhejiang to investigate the epidemic prevention and control and the resumption of work and production. During the investigation, he found that infectious disease buildings or public health clinical centers have been established in most regions, which play an important role in the treatment of critical patients in the epidemic. However, in the stage of normalization prevention and control, the buildings are often empty, and the operation and maintenance costs are very high. In response to the embarrassing situation of "insufficient supply of beds in wartime and innocent waste of resources in peacetime", Cai Xiujun has been thinking that we must make up for weaknesses, plug loopholes and strengthen weak points. The idea of building medical resources and talents that can be used in ordinary and emergency situations, and building a "combination of anti-epidemic and anti-epidemic" ward was born at that time. At that time, the Qingchun Hospital of Shaw Hospital of Zhejiang University was preparing to build the fifth phase building, and Cai Xiujun decided to "write articles" in the new building. He aimed at the most common "door" and invisible "air pressure" in the ward: on the basis of the original design of 500 beds, he adjusted the functional layout by adding "isolation door" and "positive and negative pressure device" to realize the rapid switching and seamless connection between the general ward and the respiratory infection ward. Once the "war epidemic" starts, close the isolation door and start the positive and negative pressure device, the general ward can meet the requirements of "three zones and two channels", quickly switch to the respiratory system infection ward, and the relevant ward will immediately enter the isolation state; When there is no major epidemic, these wards still perform their duties for daily medical use. In August 2022, the country's first real "combination of anti-epidemic treatment" rapid switching ward was officially put into use. Press the button to quickly switch the pressure gradient, close the isolation valve, and the buffer zone pressure gauge displays "- 10Pa". "We have launched the rapid switching mode of" combination of epidemic prevention and control "in the ward, and the general ward has been quickly switched to an infectious ward that meets the requirements of" three zones and two channels ". At present, the negative pressure state has been achieved in the buffer zone, and the micro-negative pressure state has also been achieved after the independent exhaust device in the" pollution zone "ward is synchronously started. The" polluted "air in the negative pressure state area is filtered by the filter device and then discharged into the atmosphere." Every time the colleague comes to visit, Cai Xiujun will try to take time to accompany him personally, demonstrate and introduce how to switch from the ordinary ward to the infectious ward. Through the innovative practice experience of the hospital, Cai Xiujun refined and summarized the key points of political participation and suggestions. At the bi-weekly consultative forum of the CPPCC, the "combination of anti-epidemic and anti-epidemic" rapid switching ward mode created by the CPPCC was highly recognized by the CPPCC members, and also with the state
