[0037] As Figure 1As shown, the embodiment provides a hospital infection prevention and control system, which comprises a monitoring device 110, a ventilation device 120, and a machine room control device 130. The monitoring device 110 is arranged at the front door 150, the back door 160, and the corridor 170 of the hospital building 100, respectively, for monitoring the environmental climate data and the passenger flow at different positions in the hospital building 100. The ventilation device 120 is arranged at the front door 150, the back door 160, and the corridor 170 of the hospital building 100, respectively, for supplying air to the front door 150, the back door 160, and the corridor 170 of the hospital building 100, respectively, and the air supply amount can be adjusted. The machine room control device 130 is used for analyzing the data monitored by the monitoring device 110 and controlling the ventilation device 120 at different positions to supply air individually according to the analyzed data. That is, when preventing infection in the hospital, first, the environmental climate data and the passenger flow on the corridor 170 between the front door 150 and the back door 160 of the hospital are monitored by the monitoring device 110. Then, the data monitored at different positions are transmitted to the machine room control device 130 through a line or a signal. The machine room control device 130 analyzes the received data, judges whether there is an infection risk according to the analyzed data, analyzes the degree of infection risk at different positions, and transmits the data to the ventilation device 120 through a line or a signal again. The air supply amount of the corresponding ventilation device 120 can be controlled according to the degree of infection risk, so as to reduce the infection risk.

[0038] As shown in the embodiment, the monitoring device 110 comprises a sensor monitoring member 111 and a camera monitoring member 112. The sensor monitoring member 111 is used for monitoring the wind speed, the CO2 concentration, and the temperature in the air. The camera monitoring member 112 is used for extracting the passenger flow in the shooting area. That is, the sensor is used for monitoring the wind speed, the CO2 concentration, and the temperature in the air, and monitoring the passenger flow. Then, the degree of infection risk can be determined as a whole, so as to make a response method in time, and prevent infection. Figure 1 In the embodiment, the distance between two adjacent sensor monitoring members 111 is 8-10 m. The distance between two adjacent sensor monitoring members 111 is 8-10 m. This distance can timely determine different areas individually, so as to prevent the problem that the infection risk is increased due to large passenger flow in individual areas and different air flow rates, and the sensor monitoring member 111 is arranged at each distance to timely and accurately monitor, so as to ensure the accuracy of the monitoring data.

[0039] As shown in the embodiment, the camera monitoring member 112 comprises a camera 121 and a camera lens 122. The camera 121 is used for shooting the passenger flow in the shooting area. The camera lens 122 is used for focusing the camera 121. That is, the camera 121 is used for shooting the passenger flow in the shooting area, and the camera lens 122 is used for focusing the camera 121. Then, the passenger flow in the shooting area can be extracted, so as to determine the degree of infection risk in the shooting area.

[0040] Figure 1 ​As shown, in this embodiment, the ventilation equipment 120 is located at the top of the hospital building, and each ventilation equipment 120 is positioned between two adjacent sensor monitoring devices 111. By positioning the ventilation equipment 120 between two adjacent sensor monitoring devices 111, the data monitored by the sensor monitoring devices 111 can be fed back to the computer room control device 130. The computer room control device 130 then controls the adjacent ventilation equipment 120 on both sides of the sensor monitoring device 111 to supply air, thereby increasing the airflow speed in the area where the sensor monitoring device 111 is located, and thus preventing infection.

[0041] like Figures 1-3 As shown, in one embodiment, the ventilation device 120 includes an exhaust element 121; the exhaust element 121 is inclined downwards, with its lower side facing the front door 150; the exhaust element 121 causes air to flow upwards along its inclined direction. By using an upward-flowing airflow, air containing a large amount of potentially infectious air is blown upwards and discharged through the rear door 160, effectively reducing the risk of infection.

[0042] like Figure 1 as well as Figures 4-5 As shown, in another embodiment, the ventilation device 120 includes a blower 122; the blower 122 is inclined downwards and faces the rear door 160; the blower 122 causes air to flow downwards along its inclined direction. By using an inclined downward airflow, fresh air is blown downwards and flows towards the rear door 160, causing air containing a large amount of potentially infectious material to be blown to a lower level and discharged through the rear door 160, effectively reducing the risk of infection.

[0043] like Figures 2-5 As shown, in this embodiment, the ventilation device 120 is at an angle of 40-50 degrees to the horizontal plane. The 40-50 degree tilt angle of the ventilation device 120 ensures that the airflow has both downward and horizontal directions. When the corresponding ventilation device 120 is activated for ventilation, the airflow speed in the corresponding area is increased, ensuring the entry of fresh air, and also allowing gases with a higher risk of infection to be promptly blown out along the corridor 170 towards the rear door 160. This solves the problem that existing methods of blowing air vertically downwards prevent air from being promptly blown out of the corridor 170, or blowing air parallel to the ground prevents the removal of gases from the crowd, resulting in poor infection prevention.

[0044] In this embodiment, the ventilation device 120 includes a drive component 123, which is a stepper motor. The computer room control device 130 sends a corresponding signal to control the rotation speed of the stepper motor based on the analyzed data. By using a stepper motor for driving, different rotation speeds can be achieved according to the corresponding signals sent by the computer room control device 130, thus enabling effective control of the airflow rate based on the level of infection risk.

[0045] likeFigure 1 , Figure 2 as well as Figure 4 As shown, this embodiment also includes an alarm unit 140, used to issue early warnings for locations identified as risky by the data center control device 130. The alarm unit 140 is an alarm, and there are multiple alarm units 140, each located on one side of a sensor monitoring device 111. That is, by using multiple alarm units 140, each located on one side of a sensor monitoring device 111, when the data center control device 130 analyzes the data monitored by the monitoring device 110, and when the risk of infection in a certain area increases, the data center control device 130 issues an alarm signal for that area, causing the alarm units 140 in that area to sound an alarm, thus reminding personnel to evacuate, and coordinating with the ventilation equipment 120 to reduce the risk of infection in that area.

[0046] like Figure 1 , Figure 2 as well as Figure 4 As shown, during implementation, the computer room control device 130 analyzes the data monitored by the monitoring device 110 and then makes a judgment based on the analyzed data. The ventilation equipment 120 will be activated when an infection risk is detected, and the air exchange rate will be adjusted according to the level of risk. The alarm unit 140 will only sound an alarm when the infection risk reaches a predicted ratio, and the predicted ratio of infection risk will not exceed 10% when the alarm is triggered. When it is less than 10%, the ventilation equipment 120 alone can effectively reduce the risk, while when it exceeds 10%, the patient needs to be evacuated. In other words, the ventilation equipment 120 can be activated in a timely manner, while the alarm unit 140 has a delayed activation. This ensures normal air exchange without triggering a constant alarm, which could lead to panic or prolonged alarms that could cause staff to become immune to the risk, resulting in the inability to evacuate patients in a timely manner when the actual risk increases.

[0047] During implementation, a disinfection device is installed along the path of the ventilation equipment 120. The disinfection device can disinfect the infection sources it passes through to a certain extent. The disinfection device can use a mesh screen and absorbent disinfectant liquid.

[0048] In summary, this utility model provides a hospital infection control system. First, monitoring equipment monitors environmental climate data and pedestrian flow in hospital corridors. Then, the data monitored at different locations is transmitted to the control device in the computer room. The control device analyzes the received data and controls the air volume of the corresponding ventilation equipment according to different levels of infection risk, thereby reducing the risk of infection.

[0049] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the same; although the present application has been described in detail with reference to the foregoing examples, those of ordinary skill in the art will understand that they can still modify the technical solutions described in the foregoing examples, or make equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
