At present, this is a critical period to fight the epidemic, except "? Mask? 」、「? Goggles? 」、「? Protective clothing? In addition to these medical supplies, there is a more professional medical equipment, that is, negative pressure ambulance.
Compared with ordinary ambulances, the biggest difference of negative pressure ambulances is "negative pressure". As for negative pressure, everyone in junior high school physics has learned that air will flow from the high-pressure area to the low-pressure area, just like when you are driving, the wind will pour in from the window.
Its working principle is that part of the air in the car is pumped by negative pressure equipment, and the air pressure is controlled to be lower than that outside the car, so that fresh air can enter the car from above and be discharged from below, so that the air flow direction of the whole negative pressure car cabin is from top to bottom, and no circulating air will be generated.
Because the patient in the ambulance is lying down and the medical staff is sitting, it will not lead to cross infection. Moreover, the air discharged below is also treated sterile air, which will not pollute the surrounding environment.
Of course, in addition to the negative pressure device, the air conditioning system and air filtration and disinfection system of the whole vehicle should also meet the national standards, and there are strict requirements for filters, disinfection lamps and other equipment.
In addition, the negative pressure ambulance itself is equipped with common medical emergency equipment, so it is not only an ordinary ambulance, but also can undertake the responsibility of isolating and transporting patients.
Domestic production of negative pressure ambulances are generally "? SAIC· Chase's V80? 」、「? Futian scenery G9? 」、「? Fujian Benz Weiwei? 」、「? Jiangling Ford transit? 」、「? Brilliance jinbei? " And so on.
Generally, it takes two weeks to produce a prototype car and two weeks to install and modify it, so it takes at least 30 days to produce a negative pressure car. I heard that some car companies will produce 60 cars within 10 days after receiving the requirements from the Ministry of Industry and Information Technology. Even during the Spring Festival holiday, the factory was put into production at the first time.
Not only do they build cars, but some car companies also temporarily set up production lines for masks and disinfectant to try their best to solve the shortage of medical materials. /kloc-0.4 billion people are United, what kind of hurdles can they overcome?
In the face of the epidemic, protecting ourselves is the greatest help to front-line staff, and as a means of transportation for us to travel, the prevention and disinfection in the car is of course the top priority.
Because many car wash shops haven't opened yet, I wanted to do it myself, but can I use 84 disinfectant in the car? How to do disinfection and prevention work in the car?
The person who said "84 disinfectant and 75% medical alcohol" mentioned on the Internet has his regrets. When these are used to wipe the leather inside the car, the leather will be corroded to white, and this damage is irreversible.
And because it is highly alcoholic, it is no joke to accidentally touch an electrostatic fire source in the car.
Disinfectant can be used, but be careful. Its composition includes sodium hypochlorite, which is highly oxidizing. If it can directly burn your black trousers white, it must be diluted with 200 times of water in proportion.
Then spray disinfection with peracetic acid. Before use, the stock solution of peracetic acid must be diluted to 0.2%~0.5% by adding water. Because peracetic acid is volatile, it is best to mix it. Moreover, the peracetic acid stock solution is corrosive, so you must wear rubber gloves when preparing the solution, and remember not to disinfect the metal surface inside the car. After all, ventilate for more than half an hour, and then get into the car.
Another method is to prepare a solution of 1%~3% with Su Shui and water, and spray it for 30~40min to disinfect the surface of objects in the car.
But don't forget, besides disinfection in the car, you should also take precautions when driving. If it is in a sparsely populated and empty place, be sure to open the window for ventilation before getting on the bus. If you are in a closed environment such as an underground parking lot, it is recommended to close the window and open the internal circulation. If many people ride at the same time, it is still recommended that you wear masks in the car.
