Description

Technical Field

[0001] The present invention relates to the technical field of hospital air purification, and in particular to an air disinfection and micro-negative pressure fresh air system for a digestive endoscopy center. Background Art

[0002] During the diagnosis and treatment of digestive endoscopy, the patient's oral cavity and pharynx secrete and discharge mucus, which may cause the patient to choke and vomit; the examination stimulates the intestinal discharge of a large amount of feces, blood, and waste gas; the high-pressure gas injected into the gastrointestinal cavity during the operation can splash from the gastrointestinal tract or the endoscope channel to the objects or air environment around the operator, causing air pollution and increasing the risk of pathogenic microorganism infection for medical staff; in some special operations, anesthesia and even endotracheal intubation have the risk of virus contact or air transmission; in special operations, electrocoagulation and electroresection are often performed for a long time, and the smoke formed by the rapid carbonization of the diseased tissue, etc., will affect the health of medical staff. In the cleaning and disinfection of digestive endoscopes, contaminated endoscopes and accessories need to be cleaned and disinfected at close range. During the cleaning and disinfection process, the disinfectant, enzyme solution and other chemical substances evaporate and the harmful substances such as benzene and phenols produced after chemical reactions are dispersed into the air, which irritate the human respiratory tract, eyes and skin, and may cause allergies, and may even have carcinogenic effects in the long term. Moreover, contaminated endoscopes carry the patient's pathogens, and viruses and bacteria in the respiratory and digestive systems may form aerosols and droplets during the cleaning and disinfection process, thereby causing cross-infection among staff. They may also attach to the surface of the disinfected endoscope with air and cause cross-infection among patients. Therefore, the air quality requirements in the cleaning and disinfection room are relatively high.

[0003] At present, in the digestive endoscopy center, when using the indoor fresh air system, the basic principle of the fresh air system is to suck the outdoor air into a machine with filtering function and discharge the filtered air into the room. Among them, the fan is one of the key components to realize the gas suction into the fresh air system and discharge.

[0015] The air inlet 1 and the air outlet 2 are located opposite to each other, and the air induction mechanism 4 includes a motor, an impeller 6 and a volute 7. The output end of the motor is connected to the impeller 6, and the impeller 6 is arranged inside the volute 7 along the air inlet end.

[0016] The inner wall of the cabinet 3 is radially provided with a plurality of flat keys 8, which are distributed in a spiral shape, and there are spiral channels between the flat keys 8. Filter components 5 are provided in the air outlet 2 and the air inlet 1, and the air of the fresh air circulation can be filtered. A movable cleaning mechanism is provided in the air outlet 2 and the air inlet 1, and the dust filter screen can be continuously cleaned to avoid dust clogging of the dust filter screen. A plurality of flat keys 8 are provided, and the structure is similar to the inner rifling of a pistol, which accelerates the speed of the wind and ensures that the circumferential wind can be effectively discharged from the air outlet 2.

[0017] The filter assembly 5 includes a coarse-effect filter 9, a medium-effect filter 10 and a high-efficiency filter 11 in sequence, and the medium-effect filter 10 and the high-efficiency filter 11 both include an outer frame and filter materials.

[0018] The outer frame of the coarse filter 9 is made of moisture-proof and water-resistant raw wood fiber paperboard. This material is light in weight, easy to install, and has a smooth and beautiful appearance. The design of the outer frame can be a paper frame, an aluminum frame, a galvanized iron frame, etc. The filter material is made of high-quality polyester synthetic fiber PET (non-woven coarse filter cotton), which has the characteristics of low initial resistance and large dust holding capacity. The filter material can be non-woven fabric, nylon mesh, activated carbon filter material, metal mesh, etc. The internal filter material adopts a combined inner frame compression design or bonding technology to ensure the sealing of the filter and prevent leakage.

[0021] There are two main types of partition materials for high-efficiency filters: ‌Separator filter‌: Use offset paper, aluminum foil and other materials folded as partitions, usually ultra-fine glass fiber filter paper. This filter uses offset paper or aluminum foil to separate the filter layers and uses a new type of polyurethane sealant to seal.

[0022] ‌Partitionless filter‌: Mainly uses hot melt adhesive as the filter element partition, there is no physical partition, so it is small in size and suitable for handling large amounts of air. It is often used in homes or small places‌.

[0023] The frame of the high efficiency filter 11 is made of aluminum alloy profile, multi-layer plate frame, aluminum plate frame or galvanized steel plate frame, among which the aluminum alloy profile frame is the most common choice. The design of the frame is mainly a cubic structure to provide stable support and installation interface. The impeller 6 is a centrifugal impeller 6 .

[0024] The volute 7 is a streamlined volute 7 .

[0025] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto.
