Does this mean that the pneumonia epidemic caused by novel coronavirus will be effectively treated in the near future?
The answer is no, the brother of the commercial vehicle industry naturally dare not assert anything about the medical industry.
The contribution of commercial vehicles can not be ignored.
Since the outbreak of novel coronavirus, countless medical workers and people in related industries have been actively involved in the first-line rescue and security work. As one of the pillar industries, the commercial vehicle industry is naturally not inferior.

A few days ago, my brother made a brief inventory of the "big green", "big orange", "little yellow" and "big red" who served as the exhibition director in the construction task of Huoshenshan Hospital. We all ignore another important group in the commercial vehicle industry-special purpose vehicles.
General purpose vehicles (dump trucks, trucks, excavators, road rollers, etc.). ) Help build Vulcan Mountain and Thunder God Mountain hospital, ensure the timely transportation of materials, and provide "battlefield" and "sufficient ammunition" for medical staff.
In this pneumonia epidemic war, special vehicles have also made great contributions: they have also played a unique role in rescuing patients in the early stage of the epidemic, disinfection and sterilization in urban communities in the middle stage of development, and medical waste treatment in the later stage.
Let's let my brother have a good look at those special models that are easily overlooked.
negative pressure ambulance
Because it is rare, it is easier to be ignored. As one of the important tools to treat epidemic situation, negative pressure ambulance is facing such a problem.
As we all know, at present, novel coronavirus has two very obvious characteristics-strong transmission and fast transmission, which is one of the reasons for the increase of confirmed cases in various regions after the outbreak of the epidemic.
○? Figure Negative pressure ambulance
Therefore, around the core point of virus-infected people, it is very important to transport them safely and timely to the treatment point, and it is very important to choose reasonable and effective vehicles, for which negative pressure ambulances are born.
According to my brother's understanding, the negative pressure ambulance is different from the general ambulance. In addition to the effect of emergency rescue, it can also treat the air harmlessly.
○? Figure 3 Working principle of negative pressure ambulance
○? Figure 1 disinfection system operation panel
What do you mean? To put it bluntly, it is the process of making the air pressure inside the car lower than the air pressure outside the car through technical means, and then realizing the air flowing only from the outside to the inside of the car.
Because the air in the car can't be directly discharged to the outside of the car, this means that the risk of virus spreading to others through the air can be greatly reduced during the process of transporting patients.
However, due to the relatively strict production standards and higher technical requirements of negative pressure ambulances, the cost of this special modified car based on van models was once pushed to 600,000 yuan.

600 thousand What concept? You know the pride of FAW-only about 550,000 people liberated J7.
The cost is high, and the daily demand for first aid of infectious diseases is not great. Before the outbreak of this epidemic, negative pressure ambulances were mostly used as emergency, so the stocks in various places were scarce; At the same time, this is also one of the reasons why car companies worked overtime to catch up with production and donated negative pressure ambulances after the outbreak of the epidemic.
○? Figure-related news about negative pressure ambulance on the Internet
Negative pressure ambulance is the key to prevent cross-infection, and it is also equivalent to the protective warehouse for medical workers. Its importance is self-evident, so why not pay attention to the vehicles carrying the hope of cure?
Drug and vaccine transport vehicle
Different from the negative pressure ambulance, which is based on the principle of saving lives and saving lives, and is mainly practical and comfortable, the duty of vaccine transport vehicle is to transport goods (drugs and vaccines) to the destination quickly and in time. This kind of vehicle is characterized by small batch and short distance transportation.
Therefore, compared with the former, the latter's vehicle selection is more biased towards light trucks and micro-trucks.
○? Vaccination vaccine transport vehicle
There is also a reason for this. Most refrigerated trucks are equipped with standby power supply or generators, which can ensure that the fire can be turned off and rested in time during long-distance transportation, and also ensure the normal operation of refrigerators, thus ensuring the normal activity of drugs and vaccines and ensuring the curative effect.
In addition, most of the drug and vaccine transport carriages are made of bio-safety box materials, and are equipped with double back doors to increase the tightness and ensure the safety of vaccines.

Secondly, most of the carriages are equipped with five ventilation slots to ensure the ventilation in the carriages, so as to keep the temperature in the carriages consistent. The height between the ventilation trough and the carriage is more than 5cm, and the thickness of the refrigerator is higher than that of the ordinary refrigerated truck, so as to achieve good thermal insulation effect.
Different from ordinary refrigerated trucks, the transportation of drugs and vaccines requires extremely high temperature and vehicle reliability, so it is necessary to strictly monitor the temperature during the whole transportation process and upload the data to the monitoring platform in real time.

Therefore, choosing the second-class chassis such as light trucks with better carrying capacity and larger container volume after loading as the foundation will have more advantages than van models to some extent.
It is no exaggeration to say that this kind of carrier is the carrier to convey hope, and it is a reasonable carrier to convey hope to patients after the successful development of vaccines in the future.
After talking about transportation and treatment, let's talk about prevention.
Health and epidemic prevention spray car
As my brother said earlier, one of the main reasons why novel coronavirus's propagation speed is terrible is because of its propagation speed and mode.
At present, the main transmission routes of the virus are as follows:
Droplet transmission-refers to the infection caused by sneezing, coughing, talking droplets and direct inhalation of exhaled gas at close range;
Contact transmission-refers to the droplets deposited on the surface of articles, which contact with pollutants and then contact with oral cavity, nasal cavity, eyes and other mucous membranes, leading to infection;
Aerosol transmission-refers to the mixing of droplets in the air to form aerosol, which causes infection after inhalation.
The significance of epidemic prevention spray truck is to kill virus nuclei that may remain in the air and avoid cross-infection.
In fact, the epidemic prevention spray car is not so strange to ordinary people. It is a bit similar to ordinary sprinklers, but the former has a slightly higher scientific and technological content.
○? Soil roller epidemic prevention spraying vehicle
Like vaccine transport vehicles, spraying vehicles mostly use 4x2 light truck chassis. The liquid medicine is atomized into micron-sized fine particles by adding a high-power plunger pump, and then the atomized particles are sent to the range of 120 meters by a high-power blower, which has a very good killing effect on pathogens and microorganisms left outdoors.
According to my brother, the killing area of a 16 cubic meter tank sprayer can reach almost 3.6 million square meters in one hour, and if it encounters a main road or a block with a larger killing area, the fog gun truck based on the truck chassis will begin to show its talents.
○? The larger fog gun vehicle was requisitioned for epidemic prevention.
However, unlike special vehicles such as epidemic prevention spraying vehicles, fog gun vehicles are more widely used. Usually it can play the role of dust prevention, smog prevention, spraying and sprinkling. Participating in epidemic prevention and disinfection this time can be regarded as "temporarily transferring from regular army to epidemic prevention force."
In addition, it is worth noting that in order to reduce the breeding and spread of the virus, cities, communities and rural areas all over Hubei have successively carried out comprehensive disinfection and sterilization work.
○? Disinfection work has been carried out in all parts of Hubei Province.
Wuhan began to carry out centralized disinfection twice a day in the whole city from the 9th. In Jingzhou, 52 working vehicles set out at the same time to disinfect 30 million square meters of public areas and public facilities; In Shiyan, four fog gun trucks and two spray trucks began to concentrate on killing at 8 pm. ...
Writing here, my brother also found a truth: the whole process of epidemic prevention and control has strict and scientific organizational processes, and the lack of any one may have serious consequences.
The follow-up work on how to treat medical waste in novel coronavirus should not be ignored. What kind of process is needed? How to ensure timely and efficient? We can't miss any one.
Let's look down, the medical waste transfer car is prepared for this moment.
Medical waste transfer vehicle
As the name implies, these vehicles are mainly engaged in the transportation of medical waste, which is almost the aftermath.
During epidemic prevention, masks used by ordinary people can be regarded as ordinary household garbage, but masks worn by suspected isolated patients, confirmed infected people and medical workers should be treated with caution.
○? Figure 1 Medical Waste Transfer Vehicle
In particular, infected people and doctors wearing masks should be treated as toxic waste of medical waste, especially in novel coronavirus, which has the ability to spread droplets. It is the surest way to prevent cross-infection to treat these toxic wastes by special personnel.
Medical waste transfer vehicle is specially designed for medical waste, which has the characteristics of good sealing, easy cleaning, ultraviolet sterilization and low temperature transportation.
○? The large-size double back door design makes the box more closed and more convenient to operate.
Medical waste transfer trucks are mostly made on the basis of light trucks, and their appearance is similar to that of ordinary refrigerated trucks. They have good passability in urban traffic and can also take into account the load. Their working principle is a bit like the combination of negative pressure ambulance and drug vaccine transport vehicle introduced above.
○? Figure "zero contact" medical waste transfer vehicle
Relevant data show that when medical waste is placed in the transport cabin, due to the low temperature environment and sealing, the bacteria in the cabin will not multiply rapidly and fly outdoors, and the ultraviolet setting in the cabin will also kill all kinds of microorganisms and viruses inside.
The design adopts closed transportation, the back door is double-layer closed structure, and the carriage is completely closed with labyrinth sealing strips to prevent the spread of medical waste bacteria and toxic gases;
The inner wall of the carriage is made of stainless steel plate, which can be disinfected with corrosive disinfectant. The bottom and corners of the carriage should be rounded, and the dead corners should be cleaned to facilitate disinfection.
From source treatment to drug transportation, from prevention to medical waste transport, we see that there are corresponding special vehicles to operate in all links, but these vehicles are all facing the same difficulties when the epidemic comes: insufficient reserves, large demand and challenging production capacity.
Current situation of special purpose vehicle market
In fact, there is a paradox between special purpose vehicle and general workshop. Dump trucks can also be called special vehicles, but because of the large demand and large inventory, ordinary people naturally will not equate them with special vehicles. Therefore, in some cases, it is no problem to define whether a car is a special purpose car or a general purpose car by market share.
At present, Suizhou, as the special purpose vehicle capital of China, has nearly 200 special purpose vehicle manufacturers, including Licheng in Hubei and Wuhuan in Hubei. Most of them buy secondary chassis from mainstream OEMs such as FAW, Dongfeng and Shaanxi Automobile, and then resell them.
According to the different uses, the price of special cars is also very different, which is basically the chassis price (roughly fixed)+equipment price (floating change) = vehicle price, and the same model is much more expensive than ordinary models.
The medical vehicles mentioned above are also different from ordinary special vehicles, because special medical equipment needs to be installed, so before sales, manufacturers need to sign relevant agreements with national regulatory authorities before they can sell.
In addition, in addition to the negative pressure ambulance mainly produced by SAIC Chase, Jiangling Ford, Brilliance Group and other manufacturers specializing in the production of van models, there are also many modification factories for the other three models.
Although the commercial vehicle market in China experienced a tragic year-on-year decline of 9.94% in 2065438+2008, it is believed that the future special purpose vehicle market will receive more attention with the help of this epidemic.
Problems existing in China's medical logistics system
As a commercial vehicle media, medical logistics and medical vehicles are involved to some extent. In view of the phenomenon exposed by this epidemic, I would like to express my personal views.
The epidemic has pushed the demand for various medical special vehicles to the peak, but the standards, quantity, challenges and future development of special vehicles do not seem to attract much attention.
○? Negative pressure ambulances donated by enterprises were sent to epidemic areas.
It is not difficult to find that the reasons for this situation are mostly because China's pharmaceutical logistics started late and developed immature, and it has always been in a subordinate position; The obvious reserve of medical vehicles also reflects the imbalance of commercial vehicle stock in China.
In view of these problems, if you are interested, my brother will talk alone, that's all.
Write it at the end
Every difficulty is a kind of exercise for a person, is it also true for a country? The commercial vehicle industry is not only cold, but also affectionate.
