[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The air environment management system of the intensive care unit of the present invention can monitor and detect the temperature, humidity and carbon dioxide concentration of the air environment in the intensive care unit through the sensor module. In conjunction with the air-conditioning system of the intensive care unit, it can automatically manage and adjust the temperature and carbon dioxide concentration of the air environment, and can adjust and manage the humidity through the set humidification and atomization module; because the sensor module is arranged inside the filter wall box, and the air flow inside the filter wall box is driven by the axial flow blower to circulate continuously, the captured temperature, humidity and carbon dioxide concentration data will be more accurate, which is more precise than the sensor arranged inside the air-conditioning system.

[0016] The present invention covers the top of the bed through the set bed top cover ring and the air curtain gap plate, and uses the air curtain generated by the downward exhaust of the air curtain gap plate to play a gas isolation and protection function for the patient in the bed. In the case of multiple visitors, the droplets generated by sneezing and communication can be blocked and changed to a downward direction by the blowing of the air curtain, thereby improving the protection of the patient; and because the filter wall box is arranged at the bottom, the ground dust generated by multiple people walking will be captured and filtered by the filter wall box at the first time, greatly reducing the dust in the ward and ensuring the air quality; and the provided bed curtain track structure cooperates with the air curtain gap plate, so that when the bed curtain is used, the downward blowing air curtain can be used to press the bed curtain around the bed, so as to prevent the curtain from being blown away by external interference wind or the airflow generated by the patient lifting the quilt.

[0017] The rack shaft mechanism can drive the filter element plate frame to move downward. When the filter element plate frame is lower than the air inlet grille, the filter element plate frame can be impact-cleaned, thereby preventing cleaning dust from flying out through the air inlet grille, thereby achieving dust protection. In the process of driving the filter element plate frame downward, the ultraviolet germicidal lamp can be driven downward simultaneously. When the ultraviolet germicidal lamp moves downward, it can cooperate with the external scraper ring to wipe the surface of the ultraviolet germicidal lamp to ensure the light intensity transmittance of the ultraviolet germicidal lamp and maintain the high efficiency of the ultraviolet germicidal lamp during use.

[0036] A lamp tube holder 715 is fixedly provided at the upper end of the top rod shaft 703, and the lower end of the ultraviolet sterilization lamp tube 9 is connected to the lamp tube holder 715 and installed. An external scraper ring 716 is installed on the outer sleeve of the ultraviolet sterilization lamp tube 9, and an inner cotton ring 717 is fixedly provided on the inner surface of the external scraper ring 716.

[0037] An air path wall tube 301 is provided between the axial flow blower 3 and the sterilization pipe 6, and an air inlet grid hole 719 is opened through the surface of the filter wall box 7. When the top rod shaft 703 is in an upward state, the filter element plate frame 8 is located above the air inlet grid hole 719. When the top rod shaft 703 is in a downward state, the filter element plate frame 8 is located below the air inlet grid hole 719. A guide slope 720 is fixedly provided on the inner wall surface of the filter wall box 7. The guide slope 720 is located below the air inlet grid hole 719. A dust box 721 is provided below the guide slope 720, and the dust box 721 can be pulled out for cleaning.

[0038] The outer surface of the guide slope 720 is fixed with spring supports 801 near the four corners, and a lifting spring 802 is fixed on the upper part of the spring support 801. The lower surface of the filter element plate frame 8 is pressed and installed on the upper end position of the lifting spring 802, and the interior of the filter element plate frame 8 is provided with corrugated filter paper 803.

[0039] A cross-frame ridge 804 is fixedly provided inside the filter element plate frame 8, and the cross-frame ridge 804 is located above the corrugated filter paper 803. A top pressure plate 805 is fixedly provided on the surface of the cross-frame ridge 804, and the top rod shaft 703 corresponds to the top pressure plate 805 up and down. A module wall panel 1001 is fixedly installed on the inner wall surface of the filter wall box 7, and the sensor module 10 is fixedly installed on the outer surface of the module wall panel 1001. A temperature sensor, a humidity sensor and a carbon dioxide concentration sensor are provided inside the sensor module 10. The temperature sensor can detect the temperature of the air flow passing through, the humidity sensor can detect the air humidity in the environment, and the carbon dioxide concentration sensor can detect the carbon dioxide concentration in the air environment. When the carbon dioxide concentration is too high, the PCB electronic control board can control the ward air-conditioning system to perform external circulation.

[0040] When the present invention is in use, the bed top cover ring 1 is installed on the lower surface of the ceiling of the intensive care unit ward by screws, and corresponds to the upper and lower parts of the bed. The axial flow blower 3 is installed above the ceiling and is connected to the bed top cover ring 1 through the air supply pipe 4 passing through the ceiling. The humidification atomization module 5 is connected to the clean water supply pipeline. The sterilization pipeline 6 and the air path wall pipe 301 are all embedded and concealed inside the ward wall. The filter wall box 7 is embedded in the wall, and the front surface of the filter wall box 7 is flush with the wall surface, and the filter wall box 7 is set close to the ground.

[0041] The axial flow blower 3 drives the gas flow, and the air flows in through the air inlet grid hole 719, is filtered by the corrugated filter paper 803, and then is detected by the sensor module 10, and then enters the sterilization pipe 6, and is sterilized under the radiation of the ultraviolet sterilization lamp 9. The clean air after treatment flows into the axial flow blower 3 through the air path wall tube 301, and is input into the air supply connecting pipe 4 under the drive of the axial flow blower 3, and then passes through the bed top cover ring 1 and is ejected downward from the gap of the air curtain gap plate 2 to form an air curtain, which is distributed around the bed, ensuring that the air around the patient is clean. The air curtain is blown by the air curtain, and the droplets generated by people sneezing and communicating can be blocked and changed to fly downward, thereby improving the protection of patients. Moreover, since the filter wall box 7 is arranged below the ground, the ground dust generated by people walking around the bed will be captured and filtered by the filter wall box 7 at the first time, which greatly reduces the dust in the ward and ensures the air quality. When using bed curtains, the downward-blown air curtain is used to press the curtains around the bed to prevent the curtains from being blown away by external interference wind or the airflow generated by the patient lifting the quilt.

[0042] The sensor module 10 is internally provided with a temperature sensor, a humidity sensor and a carbon dioxide concentration sensor. The humidity sensor feeds back the detected value to the PCB electronic control board. When the humidity is lower than the preset range, the PCB electronic control board controls the humidification atomization module 5 to generate water mist, and humidifies the airflow passing through the air supply pipe 4, thereby achieving humidity regulation; the temperature sensor and the carbon dioxide concentration sensor detect the airflow passing through the sensor module 10, and feed back the detected value to the PCB electronic control board. The PCB electronic control board controls the temperature rise and fall or the internal and external circulation switching of the ward air-conditioning system through the WIFI module. Since the sensor module 10 is arranged inside the filter wall box 7, and the airflow inside the filter wall box 7 is driven by the axial flow blower 3 to circulate continuously, the captured temperature, humidity and carbon dioxide concentration data will be more accurate, which is more accurate than the sensor arranged inside the air-conditioning system.

[0043] At intervals, the system will pause the axial flow blower 3 for self-cleaning. At this time, the reduction motor 713 runs, driving the vertical slot clamping teeth 712 to rotate. The vertical slot clamping teeth 712 engage with the vertical slot inner teeth 711 to drive the top rod shaft 703 to descend. The lower end of the top rod shaft 703 presses on the upper surface of the top pressure plate 805, so that the top pressure plate 805 drives the filter element plate frame 8 to move downward and compress the lifting spring 802. When the filter element plate frame 8 moves down to the height below the air inlet grid hole 719, the reduction motor 713 stops rotating, so that the top rod shaft 703 remains stable. At this time, the electromagnet 709 is fed with a pulsed intermittent current to generate a gap magnetic force, which attracts the lifting suction cup 707 to move upward. When the magnetic force disappears, the lifting suction cup 707 is pulled downward by the elastic tension of the tension spring 708, causing the punch shaft 706 to hit the top pressure plate 805. 719, so that the dust adsorbed on the lower surface of the corrugated filter paper 803 can be shaken off and collected in the dust box 721. Moreover, since the height of the corrugated filter paper 803 is lower than the air inlet grille 719 at this time, the dust can be prevented from escaping, and self-cleaning can be achieved while avoiding the occurrence of dust. Moreover, during the descending process of the top rod shaft 703, the ultraviolet sterilization lamp tube 9 can be driven to descend. After a long period of gas passing through the surface of the ultraviolet sterilization lamp tube 9, a small amount of dust particles missed by the filtration will accumulate, affecting the light transmittance of the ultraviolet sterilization lamp tube 9 and weakening the ultraviolet sterilization light intensity. At this time, the external scraper ring 716 can scrape and clean the outer surface of the ultraviolet sterilization lamp tube 9 through the inner cotton ring 717, so that the surface of the ultraviolet sterilization lamp tube 9 remains bright and the ultraviolet light intensity is maintained.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
