Description

Technical Field

[0001] The present invention relates to the technical field of infectious disease protection and isolation, and in particular to an isolation device for treating infectious diseases. Background Art

[0002] Respiratory isolation is used for diseases where pathogens are transmitted through the respiratory tract, such as novel coronavirus infection, influenza, measles, diphtheria, whooping cough, and epidemic cerebrospinal meningitis. Essential isolation measures include wearing a mask, hat, and isolation gown when approaching patients, and keeping them dry. Patients should also wear masks when visiting other departments for consultation or treatment. Respiratory secretions must be disinfected before being poured into a dedicated sewer or incinerated. In-patient air is disinfected daily.

[0003] However, even when medical staff or patients wear masks or protective clothing, there is still a risk of infection. This is because medical staff need to be close to patients to provide treatment, and the gas and droplets containing pathogens produced by patients' coughing and breathing can escape through the gaps in the mask, which also poses a risk of infection to medical staff. Therefore, those skilled in the art have proposed an isolation device for the treatment of infectious diseases. Summary of the Invention

[0043] Example 2: Air disinfection example:

[0044] System startup and negative pressure suction stage: Scenario simulation, the patient suddenly coughs violently, generating droplet aerosols containing pathogens with a particle size of 0.5-10μm.

[0045] 1. Core component linkage: The driving motor 27 drives the turbofan 24 at a speed of 2800r / min, forming a dynamic negative pressure field of -50Pa to -80Pa in the negative pressure droplet suction mechanism 2. The wind collecting hood 32 forms a directional suction airflow with a flow rate of 1.2m / s through the gooseneck tube 31, which can capture 0.8m in front of the patient's mouth and nose within 5 seconds. 3 More than 90% of the droplets in the space are removed; the sealed bearing built into the front cover 22 ensures the dynamic sealing of the motor shaft to prevent gas leakage.

[0046] 2. Primary Aerosol Treatment: Contaminated air enters the air inlet duct 42 through the outlet nozzle 25. The solenoid valve 41 adjusts its opening using a PID algorithm to maintain system pressure fluctuations below ±5 Pa. A built-in barometer monitors the pressure in real time, triggering an audible and visual alarm when the pressure differential exceeds a threshold.

[0047] 3. Multi-stage filtration and purification:

[0048] Filter module: The air filter element 45 uses H13 grade HEPA filter material, and an activated carbon layer is embedded in the filter housing 46 to adsorb volatile organic compounds.

[0049] 4. Deep disinfection by mist spraying:

[0050] Disinfection subsystem: Servo pump 51 delivers hypochlorous acid disinfectant with an effective chlorine concentration of 200 ppm at a pressure of 0.25 MPa. Six groups of atomizing nozzles 56 form 3 μm droplets, which remain in contact with the airflow in the opposite direction for ≥ 2 seconds.

[0051] Circulatory system:

[0052] The reflux pipe 57 realizes the dynamic circulation of the disinfectant and is equipped with a UV-C ultraviolet module to maintain the sterility of the solution. A conductivity sensor is set to monitor the concentration of the disinfectant in real time and automatically replenish the original solution.

[0053] 5. Clean air emissions:

[0054] The treated air is discharged through the air outlet duct 43, and the PM2.5 concentration is less than 10μg / m 3 , and an ozone monitoring module is installed at the end to ensure that the exhaust gas meets WHO safety standards.

[0055] According to the content of the above-mentioned preferred technical solution, the workflow of the technical solution is explained as follows:

[0056] By utilizing the effect that the gooseneck tube 31 can be bent and positioned, the wind collecting hood 32 is kept facing the patient's face. After the patient exhales the gas containing pathogens, the wind collecting hood 32 and the gooseneck tube 31 guide the gas to the inside of the air intake nozzle 26. After the drive motor 27 drives the turbofan 24 between the rear end cover 23 and the front end cover 22 to rotate, the negative pressure suction force generated transports the gas along the air outlet nozzle 25 to the filter housing 46. The solenoid valve 41 can control the gas entering the filter housing 46. Under the blocking effect of the air filter element 45, the pathogens contained in the gas are adsorbed by the air filter element 45, and the gas that is not filtered clean will enter the spray tank 44 along the connecting pipe 47.

[0057] At this time, the servo water pump 51 will extract the disinfectant from the disinfectant tank 54 through the liquid extraction pipe 53, and transport the disinfectant to the atomizing nozzle 56 through the hose 52 and the manifold 55. The atomizing nozzle 56 will spray the disinfectant from top to bottom. The gas inside the spray tank 44 will be purified by the atomized disinfectant to kill the bacteria therein. At the same time, the disinfectant will flow back to the disinfectant tank 54 along the reflux pipe 57, and the purified gas will be discharged back to the treatment environment along the air outlet duct 43.

[0058] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention.
