[0015] Example 1

[0016] In order to solve the technical problems raised in the background technology, the present application provides a preferred embodiment: Figure 1 As shown in Figure 1, an infection risk assessment method for operating room care includes the following specific steps: Step 1: Obtain virus transmission data and environmental data in the operating room, and obtain data on medical protective equipment of medical staff in the operating room; In one specific embodiment, the specific contents of obtaining virus transmission data and environmental data in the operating room, and obtaining data of medical protection equipment of medical staff in the operating room are: Step 11: Obtain virus transmission data in the operating room, wherein the virus transmission data includes the maximum transmission distance of the virus and the transmission probability at the maximum transmission distance; and it should be noted that the maximum transmission distance of the virus and the transmission probability at the maximum transmission distance are obtained according to the virus transmission experiment process, for example, the maximum transmission distance of the influenza virus is 1 to 2 meters, and the transmission probability decreases as the transmission distance increases; Step 12: Obtain location data of medical staff in the operating room who are close to the infection source. The location data here is relative to the location of the infection source. At the same time, obtain environmental data in the operating room, where the environmental data includes temperature and ventilation flow data in the operating room. Step 13: Obtain the protection level data of medical protective equipment used by medical staff in the operating room. The protection level of medical protective equipment against infection is usually divided into several different levels. Different protective measures are taken according to the type of pathogens that may be exposed, the degree of risk, and the mode of transmission. The following are some common medical protective equipment and their corresponding protection levels: General protection: suitable for low-risk scenarios, such as general outpatient clinics, general wards, etc. Mainly use basic personal protective equipment, such as work clothes, masks, gloves, etc.; Level 1 protection: Applicable to places such as pre-examination and triage, fever clinics, etc., which may involve contact with potentially infectious patients. Protective measures include wearing disposable work caps, medical surgical masks, work clothes, disposable isolation gowns, disposable gloves, etc.; Level 2 protection: Applicable to medical personnel who enter the isolation ward for infectious diseases or multidrug-resistant bacteria, touch specimens collected from patients, handle their secretions and excretions, and perform other high-risk operations. They need to wear medical protective masks (N95 or higher level), protective glasses or face shields, medical protective clothing, latex gloves, and shoe covers; Level 3 protection: Applicable to aerosol-generating operations for patients with infectious diseases or multidrug-resistant bacteria, such as sputum suction, respiratory sampling, endotracheal intubation, etc. On the basis of level 2 protection, further strengthening of protection is required, which may include the use of full-face respiratory protective devices or higher-level powered air-purifying respirators, etc.; Step 2: Perform virus transmission analysis in the operating room based on virus transmission data and environment data in the operating room; In one specific embodiment, Figure 2 As shown, the analysis of virus transmission in the operating room based on virus transmission data in the operating room and environmental data in the operating room includes the following specific steps: Step 21: Obtain the virus transmission data in the operating room and the location data of the medical staff in the operating room away from the infection source, and substitute them into the virus transmission abnormal value calculation formula to calculate the virus transmission abnormal value of the medical staff, where the virus transmission abnormal value calculation formula of the u-th medical staff is: , where tu is the time the u-th medical staff is in the operating room, xm is the transmission probability at the maximum transmission distance, Lm is the maximum transmission distance, Lut is the location data from the u-th medical staff to the infection source at time t, dt is the time integral, and e is a natural constant. is the transmission coefficient, which is used to reflect the speed of virus transmission from different infection sources, and its value range is 0 to 1; Step 22: Obtain the environmental data in the operating room, and import the environmental data in the operating room into the environmental impact value calculation formula to calculate the environmental impact value, wherein the environmental impact value calculation formula is: , where s is the temperature coefficient, Tw is the operating room temperature, Tm is the optimal growth temperature of the source virus, Vw is the operating room ventilation flow, and Vm is the safe ventilation flow; First, viruses are more difficult to survive and reproduce in low-temperature environments. Therefore, keeping a low temperature in the operating room helps inhibit the activity of the virus and reduce the risk of infection. However, too low a temperature may also cause discomfort to the patient, affecting the surgical effect and recovery. Second, a high temperature environment may accelerate the death and inactivation of the virus. However, too high a temperature may also have adverse effects on surgical equipment and medical staff, such as causing equipment failure or making medical staff feel uncomfortable. Ventilation helps reduce the concentration of viruses in the air in the operating room. Through effective ventilation, the virus can be diluted and discharged outdoors, thereby reducing the risk of virus transmission in the operating room. Ventilation also helps maintain the air quality in the operating room. Operating rooms usually use high-efficiency filtration systems and proper ventilation design to capture and remove particles in the air, including viruses and other microorganisms. This can significantly reduce the microbial load during surgery and improve the quality of surgery. Step 23: Substitute the calculated virus transmission abnormality value and environmental impact value of the medical staff into the virus transmission value calculation formula to calculate the virus transmission value, wherein the virus transmission value calculation formula of the u-th medical staff is: ,Here, the virus infection assessment is conducted based on the characteristics of virus transmission and the characteristics of the operating room environment; Step 3: Conduct infection protection analysis based on the data of medical protective equipment used by medical staff in the operating room; In one specific embodiment, performing infection protection analysis based on data of medical protection equipment of medical staff in an operating room includes the following specific steps: Step 31, obtain the protection level data of each medical protective equipment of the medical staff, and at the same time obtain the historical transmission channels of the virus, such as transmission through the skin or through blood, etc. If the virus is transmitted through the skin, the corresponding protection level of the skin of the whole body should be analyzed, and if the virus is transmitted through breathing, the protection level of the face should be analyzed as the main factor, and the protection level of the whole body should be analyzed as the auxiliary factor; Step 32: Import the acquired protection level data of each medical protective equipment of the medical staff and the historical virus transmission channels into the infection protection evaluation value calculation formula to calculate the infection protection evaluation value, wherein the infection protection evaluation value calculation formula of the u-th medical staff is: , where n is the number of types of medical protective equipment, such as work clothes, masks, gloves, etc., h is the average height of medical staff, Liu is the distance from the middle position of the i-th medical protective equipment of the u-th medical staff to the transmission channel. For example, if the gloves are the i-th medical protective equipment, the transmission channel is the skin, so there is skin on the hands, so the distance from the gloves to the skin is 0. At the same time, if the gloves are the i-th medical protective equipment, the transmission channel is breathing, so the distance from the gloves to the mouth and nose is Li, Yiu is the protection level of the i-th medical protective equipment of the u-th medical staff. In this step, the protection effect is analyzed through the characteristics of the protective equipment; Step 4: Conduct infection risk assessment based on the results of the operating room virus transmission analysis and infection protection analysis in the operating room; In one specific embodiment, Figure 3 As shown in the figure, the infection risk assessment based on the results of the operating room virus transmission analysis and the infection protection analysis in the operating room includes the following specific contents: Step 41: Obtain the calculated virus transmission value and infection protection assessment value of the medical staff, and substitute the obtained virus transmission value and infection protection assessment value of the medical staff into the infection risk value calculation formula to calculate the infection protection assessment value of the medical staff, wherein the infection protection assessment value calculation formula of the u-th medical staff is: ; Step 42: Compare the calculated infection protection assessment value with the set infection protection assessment threshold. If the infection protection assessment value is greater than or equal to the set infection protection assessment threshold, a medical infection warning is issued to remind the medical staff to monitor their health. If the infection protection assessment value is less than the set infection protection assessment threshold, no medical infection warning is issued. Step 5: Providing an infection risk warning based on the obtained infection risk assessment results; In one of the specific embodiments, the specific method of infection risk warning is: transmitting the infection risk warning signal to the medical management terminal to remind the corresponding medical staff to perform health monitoring.

[0017] In one of the specific embodiments, the setting parameters in this embodiment are set as routine settings for those skilled in the art, and the optimal setting parameters (such as infection protection assessment threshold, temperature ratio coefficient and propagation coefficient, etc.) are obtained as follows: several groups of historical virus transmission data in the operating room and environmental data in the operating room, and data on medical protection equipment of medical staff in the operating room are obtained, and the data are substituted into the infection risk value calculation formula to calculate the infection protection assessment value of the medical staff, and the judgment results of whether these medical staff are infected are obtained, and the calculated infection protection assessment value of the medical staff and the judgment results of whether the medical staff are infected are imported into the fitting software, and the values ​​of the setting parameters (such as infection protection assessment threshold, temperature ratio coefficient and propagation coefficient, etc.) that meet the maximum judgment accuracy are output.
