Technical Field

[0001] The utility model relates to the technical field of air outlets in operating rooms, in particular to an air outlet purification device for operating rooms. Background Art

[0002] The operating room is a place for patients to undergo surgery and rescue, and is an important technical department of the hospital. The operating room should be connected to the surgical department, and should also be close to the blood bank, intensive care unit, anesthesia recovery room, etc. It is important to manage the four ways of surgical incision infection, namely: the air in the operating room; the items required for the operation; the fingers of doctors and nurses and the skin of patients, to prevent infection and ensure the success rate of the operation. Therefore, the operating room needs good ventilation to ensure a sterile environment in the operating room.

[0003] Existing operating room vents are generally filtered through filters. However, filtering through filters alone has poor filtering effects and is prone to breeding bacteria, which can lead to bacteria and dust in the operating room environment, making it impossible to create a good sterile environment for the operating room and even affecting the patient's health.

[0004] For example, a purification device for the air outlet of an operating room disclosed in Chinese patent CN213273054U can absorb dust in the external wind onto the filter cotton through the cooperation between the first filter screen and the filter cotton, and then the spray sprayed by the atomizing nozzle can both clean the dust on the filter cotton and reduce dust; an activated carbon layer is provided to absorb bacteria, and the bacteria can be eliminated more thoroughly in cooperation with an ultraviolet germicidal lamp; a microporous filter membrane is provided to treat smaller bacteria, and the activated carbon layer and the ultraviolet germicidal lamp are used to treat bacteria to prevent harmful bacteria from entering the operating room; water in the air inlet pipe is collected through the cooperation between the water outlet pipe and the water collecting box to prevent it from being blown into the operating room by the exhaust fan, and a water-absorbing sponge is provided to absorb water faster; a second filter screen is provided to prevent excess water and dust from entering the operating room and affecting the environment in the operating room.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0030] Embodiment 1:

[0031] An operating room air outlet purification device comprises a ventilation pipe 1, a spray disinfection structure is installed on the top and bottom of the ventilation pipe 1, a filtering structure is installed on the left and right ends of the ventilation pipe 1, and a sterilization structure is installed in the middle section of the ventilation pipe 1.

[0032] The spray disinfection structure includes a spray unit and a collection unit. The spray unit includes a liquid tank 101. A water pump 102 is installed inside the liquid tank 101. A delivery pipe 103 is connected to the output end of the water pump 102. A sealing bearing 104 is connected to the end of the delivery pipe 103 away from the water pump 102. A rotating tube 105 is connected inside the sealing bearing 104. A spiral blade 106 is installed inside the rotating tube 105. A nozzle 107 is installed at the end of the rotating tube 105 away from the delivery pipe 103. The collection unit includes a drain pipe 108. A waste liquid tank 109 is installed at the bottom end of the drain pipe 108. A circular hole is opened in the middle of the left side of the waste liquid tank 109. The end of the outer surface of the drain pipe 108 away from the ventilation pipe 1 is connected to the inside of the circular hole opened in the middle of the left side of the waste liquid tank 109.

[0033] The bottom surface of the liquid tank 101 is connected to the left end of the top surface of the ventilation pipe 1, the outer surface of the left sealing bearing 104 is connected to the inside of the mounting hole opened on the outer surface of the ventilation pipe 1, and the end of the drain pipe 108 away from the waste liquid tank 109 is connected to the inside of a circular hole opened in the middle of the bottom surface of the ventilation pipe 1.

[0034] The filtering structure includes a guide rail 201, a filter screen 202 is connected to the outer surface of the guide rail 201, a mounting frame 203 is provided on the side where the two filter screens 202 are close to each other, and a fan 204 is installed inside the mounting frame 203. The guide rail 201 is fixedly connected to the left and right ends of the ventilation pipe 1, the side where the two filter screens 202 are close to each other is sealed and slidably connected to the left and right ends of the ventilation pipe 1, the outer surface of the mounting frame 203 is fixedly connected to the inner wall of the ventilation pipe 1, and the fan 204 is installed inside a rectangular through hole opened in the middle of the left side of the mounting frame 203.

[0035] By setting up the spray disinfection structure, starting the water pump 102 can fill the disinfectant in the liquid tank 101 and transport it through the delivery pipe 103. After the disinfectant enters the rotating tube 105, the cooperation of the sealed bearing 104 and the spiral blade 106 drives the nozzle 107 to perform atomization spraying, which can make the diffusion area of ​​the disinfectant larger and have a better sterilization effect on bacteria in the airflow.

[0036] When the airflow flowing inside the ventilation pipe 1 is sterilized, the fan 204 is started for ventilation. During the ventilation process, the filter screens 202 installed at both ends are used to intercept and filter dust particles in the air, and then the water pump 102 is started to transport the disinfectant in the liquid tank 101 through the delivery pipe 103. After the disinfectant enters the rotating tube 105 through the delivery pipe 103, the spiral blades 106 and the sealed bearings 104 are used to drive the rotating tube 105 to rotate due to hydraulic reasons. During the rotation, the nozzle 107 is driven to rotate, thereby increasing the area of ​​the disinfectant atomization spraying, and having a better effect on disinfecting bacteria in the airflow. After accumulation, the atomized disinfectant flows into the waste liquid tank 109 through the drain pipe 108 connected to the bottom end of the ventilation pipe 1, wherein a one-way valve is installed inside the drain pipe 108 close to one end of the ventilation pipe 1, thereby preventing bacteria from growing and drifting into the ventilation pipe 1.

[0037] Embodiment 2:

[0038] On the basis of the first embodiment, the sterilization structure includes a limiting strip 301, an activated carbon plate 302 is connected to the outer surface of the limiting strip 301, a limiting strip 303 is arranged on the right side of the limiting strip 301, an adsorption plate 304 is connected to the outer surface of the limiting strip 303, a disinfection lamp 305 is arranged at the bottom of the adsorption plate 304, and a reflector 306 is arranged on the left and right sides of the bottom of the disinfection lamp 305.

[0039] By setting up the sterilization structure, when the disinfection lamp 305 is started for ultraviolet irradiation and sterilization, the reflector 306 can be used to refract the ultraviolet rays, thereby increasing the ultraviolet coverage area. At the same time, the activated carbon plate 302 and the adsorption plate 304 can be covered and irradiated to prevent the activated carbon plate 302 and the adsorption plate 304 from breeding bacteria due to adsorption of moisture.

[0040] After the airflow is sprayed and sterilized by the disinfectant, it is adsorbed and filtered by the activated carbon plate, and the disinfection lamp 305 is turned on at the same time for ultraviolet sterilization. During the irradiation process of the ultraviolet light of the disinfection lamp 305, the ultraviolet light can be refracted by the reflector 306, effectively increasing the ultraviolet coverage area, thereby achieving better sterilization effect. At the same time, the ultraviolet light refracted by the reflector 306 can be used to irradiate and sterilize the activated carbon plate 302 and the adsorption plate 304, effectively reducing the growth of bacteria.
