The difference between a negative pressure ambulance and an ordinary ambulance is the negative pressure. "Negative pressure ambulances are of a higher class than normal ambulances, but they are also based on normal ambulances. The "negative pressure ambulance" is equivalent to the ordinary ambulance with an isolation device, that is to say, the vehicle is completely isolated from the outside of the vehicle, so as to avoid patients with infectious diseases to spread the germs to the outside.
"Negative pressure ambulance" stretcher set up a special air recovery port, breath recovery port to the patient's exhaled gas extraction, and then filtered, sterilized and then discharged out of the car, thus avoiding the spread of germs in the air. The so-called negative pressure, the air in the compartment will be 10 to 30 pa lower than the air pressure. So even though the air in the compartment is contaminated by the patient, it will not leak out of the car and will not cause pollution of the air.
Another thing is that the air conditioning system inside the car is also different from the ordinary ambulance, which is also the key part of the negative pressure ambulance, the air conditioning filter sterilization function has strict requirements. The car will not only be equipped with ultraviolet disinfection lamps, negative pressure ambulance medical emergency equipment is also quite complete, compared to the ordinary ambulance is more complete. Many surgeries can be performed on negative pressure ambulances, while ordinary ambulances are not able to achieve such conditions.
Because of the suddenness of the epidemic, negative pressure ambulances have also become relatively scarce supplies, and there are already many car companies that have unconditionally donated negative pressure ambulances to hospitals around the world. For example, like Chery Automobile on the first day of the year emergency deployment of its Ruifengt special vehicles to resume overtime, the production of special negative pressure ambulances for patient rescue. At present, the production of negative pressure ambulance car companies are not many, Shanghai Datsun, Jiangling Motors, etc. have received the requirements of the relevant departments to request the production of negative pressure ambulance requirements.
Negative-pressure ambulances are suitable for the transportation of patients with highly contagious diseases, but also in the negative-pressure ambulance to carry out some surgery. And ordinary ambulances can not meet such requirements and standards. It is also because of the extremely high requirements, so the production of the car companies are only a few, and based on the special characteristics of the negative pressure ambulance, so it is unlikely to be mass production.
The difference between an ordinary ambulance and a negative-pressure ambulance is very great. Negative-pressure ambulances are uncommon because of their cost and use. Because of the special nature of the epidemic, so the negative pressure ambulance into people's eyes. And the ability to produce negative pressure ambulance car companies also open full power in the production, and some vehicles have been put into use, shows that our car companies do not mean to focus on the interests of the key moments, reflecting the social responsibility of the car companies. More than one production, then it will reduce the chance of cross-infection, but also faster to win the war without smoke.
