The infectious patients are transported on the ground, the isolation unit cannot be exposed in a severe air pressure change environment during transportation, the requirement and the design for maintaining constant negative pressure for a long time do not exist, only simple medical care operation is considered, and the isolation unit is not suitable for the aviation medical transportation requirement. Usually, the internal and external pressure difference of the isolation unit of the patient with the infectious disease on the ground can be maintained at negative pressure of more than 15Pa to meet the use requirement. However, in an aviation environment, due to the influence of external air pressure change and vibration, impact, acceleration and the like of the flying environment of an airplane, negative pressure is difficult to maintain constantly, two sets of air circulation control systems are designed, each air circulation control system consists of a power supply, a fan, an internal and external pressure difference sensor and a control system module, and in the take-off stage and the landing stage, the two sets of air circulation control systems work continuously to maintain the negative pressure capacity in a separation cabin and keep the negative pressure capacity above 45Pa all the time. And combined with aviation flying environment, the test verification is carried out, specifically as follows:
the initial pressure difference of the infectious disease patient conveying isolation unit is 46Pa, the air pressure change state of the aircraft in the flying process is simulated through the low-pressure cabin environment, the air pressure environment change condition of the aircraft in the flying process is artificially established, the working performance of the aircraft is tested, the test height range is 0-2438-4570 m, and the test process is height ascending, stability, descending, stability and descending (returning to the ground). The result shows that in the ground state, the initial differential pressure value is 46Pa, and the differential pressure value is always reduced along with the increase of the altitude, and basically shows a better trend. The test verifies that when the output power of the automatic filtration circulating system is unchanged, the working efficiency is reduced along with the reduction of the air pressure, when the output power is increased to 2500 m, the pressure difference is reduced to 36Pa, when the height of 2500 m is stable, the automatic filtration circulating system continuously climbs, along with the reduction of the external air pressure, the working efficiency is reduced, when the output power is increased to 4500 m, the pressure difference is reduced to 31Pa, then the internal and external pressure differences are balanced, and the pressure difference is 32Pa during balancing; after 4500 m is stabilized for a period of time, the altitude begins to descend at a speed of 10m/s according to the requirement of aircraft landing, the altitude returns to 2500 m, the pressure difference is 38Pa, after stabilization, the altitude continues to descend until the ground, and the pressure is restored to the initial pressure difference value. The result shows that the initial pressure difference of the isolation unit for transporting infectious disease patients is 46Pa, the rising speed is 10m/s, the whole height is verified according to the range of 0-2500 m-4500 m-2500-0 m, the negative pressure value inside the cabin is always maintained at 31-46 Pa, and the requirement that the pressure difference inside and outside the cabin is more than 15Pa is met, and the result is shown in detail in figure 2.
