It has been ignored before, and the future will be hot! "Special Medical Vehicle" Model and Market Inventory

On February 13th, China Bio of Sinopharm Group released the latest progress in the treatment of COVID-19: Sinopharm China Bio has completed the collection of plasma from some recovered patients, and the preparation of Covid-19 special immune plasma products and special immune globulin. After strict blood biological safety testing, virus inactivation, antiviral activity testing, etc., the special immune plasma for clinical treatment has been successfully prepared and put into clinical treatment of critically ill patients.

Does this mean that the pneumonia epidemic caused by novel coronavirus will be effectively treated in the near future?

the answer is no, and my brother who is in the commercial vehicle industry naturally does not dare to assert medical affairs.

The contribution of commercial vehicles can't be ignored

Since the outbreak of the new coronavirus pneumonia, countless medical workers and people in related industries have been actively involved in the first-line treatment and security work, and the commercial vehicle industry, as one of the pillar industries, has naturally not fallen behind.

A few days ago, my brother made a brief inventory of the "big green", "big orange", "little yellow" and "big red" who have their own strengths in the construction task of Huoshenshan Hospital. We all neglected another important group in the commercial vehicle industry-special vehicles.

General-purpose vehicles (dump trucks, trucks, excavators, road rollers, etc.) help to build Vulcan Mountain and Thunder God Mountain hospital, ensure the timely transportation of materials, and provide "battle field" and "sufficient ammunition" for medical staff.

In this pneumonia epidemic war, special-purpose vehicles also made great contributions: they also played a unique role in rescuing patients in the early stage of the epidemic, disinfecting and sterilizing urban communities in the middle stage of development, and treating medical wastes in the later stage.

let's take a good inventory of the special models that are easily overlooked.

Negative pressure ambulance

Because it is rare, it is more easily overlooked. As one of the important tools to treat the epidemic, the negative pressure ambulance is facing such a problem.

As we all know, there are two very obvious characteristics in novel coronavirus at present-strong transmission and fast transmission speed, which is one of the reasons why the confirmed cases in various regions have been rising continuously after the outbreak of the epidemic.

○? Figure è Negative pressure ambulance

So it is very important to transport the virus-infected people safely and timely to the rescue point. It is very important to choose a reasonable and effective vehicle, and the negative pressure ambulance is born for this.

according to my brother's understanding, the negative pressure ambulance is different from the general ambulance. Besides the emergency rescue function, it can also treat the air harmlessly.

○? Figure: working principle of negative pressure ambulance

○? Figure

What does the disinfection system operation panel mean? To put it bluntly, through technical means, the air pressure inside the car is lower than the outside air pressure, and then the process of air flowing only from outside the car to inside the car is realized.

Since the air in the car can't be directly discharged outside the car, it means that the risk of virus spreading to others through the air can be greatly reduced in 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 6, yuan.

○? What is the concept of 6, negative-pressure ambulances

? You know the pride of FAW-the liberation of J7 is only about 55,.

The high cost and the daily demand for emergency treatment of infectious diseases are 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 one of the reasons why after the outbreak of the epidemic, various car companies worked overtime to catch up with production and donated negative-pressure ambulances.

○? The 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 don't vehicles carrying hope for cure need to be taken seriously?

Drug and vaccine transport vehicles

Unlike negative-pressure ambulances, which give priority to practicality and comfort based on the principle of rescuing the wounded, vaccine transport vehicles are responsible for delivering goods (drugs and vaccines) to their destinations quickly and timely, and small batch and short-distance transport are the characteristics of this kind of vehicles.

therefore, compared with the former, the latter's model selection is more inclined to light truck and micro truck chassis.

○? There is also a reason for the vaccine transporter

. Most refrigerated vehicles are equipped with standby power supply or generators, which can ensure that they can turn off the fire and rest at zero o'clock in time for long-distance transportation, and also ensure the normal operation of the refrigerator, thus ensuring the normal activity of drugs and vaccines and ensuring the curative effect.

In addition, the transport carriages of drugs and vaccines are mostly made of biosafety-grade box materials, and are equipped with double back doors to increase the tightness and ensure the safety of vaccines.

○? The design of double rear doors of vaccine transport vehicle

Secondly, most of the compartments are equipped with five ventilation slots to ensure the ventilation in the compartment, so as to keep the temperature in the compartment consistent. The height of the ventilation slot from the compartment is more than 5cm, and the thickness of the refrigerator is higher than that of the ordinary refrigerator vehicle, so as to achieve good thermal insulation effect.

It is different from ordinary refrigerated trucks in that the transportation of drugs and vaccines requires extremely high temperature and vehicle reliability, which requires strict temperature monitoring during the whole transportation process, and the data is uploaded to the monitoring platform in real time.

○? Figure 2 vaccine cold chain car

Therefore, choosing the second-class chassis with better bearing capacity and larger container volume after loading, such as light truck, will have more advantages than VAN model to some extent.

It's no exaggeration to say that this kind of vehicle is the vehicle for conveying hope, and it is a reasonable vehicle for conveying hope to patients after successful vaccine development in the future.

after transportation and treatment, let's talk about prevention.

Health and epidemic prevention spray truck

As my brother said before, one of the main reasons why the spread speed of novel coronavirus is terrible this time is because of its spread 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 and talking droplets of patients and direct inhalation of exhaled gas at close range;

contact transmission-refers to that droplets are deposited on the surface of articles, and then contact with oral cavity, nasal cavity, eyes and other mucous membranes after contacting with pollutants, resulting in infection;

aerosol transmission-refers to the mixing of droplets in the air to form aerosol, which causes infection after inhalation.

The significance of the existence of epidemic prevention spray truck is to kill virus nuclei that may be left in the air and avoid cross-infection.

Actually, the epidemic prevention spray truck is not so strange to ordinary people. It is somewhat similar to ordinary sprinklers, except that the technology content of the former is slightly higher.

○? Figure è Epidemic prevention spraying vehicle

Like vaccine transport vehicles, spraying vehicles are mostly made of 4x2 light truck chassis. The 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 12 meters by a high-power blower, which has a very good function of killing pathogens and microorganisms left behind outdoors.

according to my brother's understanding, the killing area of a 16-cubic-meter tank spray truck can reach almost 3.6 million square meters in one hour, and if it meets a main road or a block with a larger killing area, the fog gun truck based on the truck chassis will start to show its talents.

○? The fog gun truck with bigger physique has been requisitioned for epidemic prevention

However, unlike the special model such as the fog gun truck for epidemic prevention, the fog gun truck is more widely used. In normal times, it can have functions of dust prevention, haze prevention, spraying and watering. This time, it is considered as "temporarily transferred from the regular army to the anti-epidemic 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 disinfection work.

○? Figure 2 Comprehensive disinfection work is carried out in all parts of Hubei < P > In Wuhan, centralized disinfection will be carried out twice a day from the 9th; In Jingzhou, 52 working vehicles set out at the same time to carry out centralized disinfection of 3 million square meters of public areas and public facilities; In Shiyan, four fog gun trucks and two spray trucks started to kill at 8: pm ...

As I wrote here, my brother also found a truth: the whole process of epidemic prevention and control has a strict and scientific organizational process, and the lack of either one may cause serious consequences.

The follow-up work of how to deal with medical waste in novel coronavirus can't be ignored either. What kind of process is needed? How to ensure timely and efficient? We can't miss any of them.

Let's look down. The medical waste transfer vehicle is prepared for this moment.

medical waste transfer vehicle

as the name implies, this type of vehicle mainly transports medical waste, which is almost a aftermath.

During epidemic prevention, masks used by ordinary people can be regarded as ordinary domestic garbage, but masks worn by suspected isolated patients, confirmed infected people and medical workers should be treated with caution.

○? Medical waste transfer vehicle

Especially infected people and doctors wearing masks should be treated as toxic waste of medical waste, especially novel coronavirus, which has the ability to spread droplets, should be properly treated, and the only way to prevent cross-infection is to treat these toxic wastes by special personnel.

Medical waste transfer vehicle is specially designed for medical waste, which has many characteristics such as good sealing, easy cleaning, ultraviolet sterilization and low-temperature transportation.

○? The large-size double back door design makes the box more closed and the operation more convenient

Most medical waste transfer vehicles are made on the basis of light trucks, and their appearance is similar to that of ordinary refrigerated trucks. They have good passability in urban transportation and can also give consideration to loading capacity. Their working principle is a bit like the combination of negative pressure ambulance and drug vaccine transport vehicle introduced above.

○? Figure

Relevant data of the medical waste transfer vehicle that can realize "zero contact" show that when medical waste is placed in the transport cabin, the bacteria in the cabin will not multiply and fly to the outside quickly due to the low temperature environment and sealing, and the ultraviolet setting in the cabin will also kill various microorganisms and viruses inside.

The design adopts airtight transportation, the back door is double-layer airtight structure, and the labyrinth sealing strip is adopted to completely close the carriage, so as to prevent the spread of medical waste germs 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 angle should be cleaned for disinfection.

From source treatment to drug transportation, from prevention and treatment to medical waste transfer, we have seen that there are corresponding special vehicles for operation in all links, but these vehicles are all facing the same difficulties when the epidemic comes: insufficient reserves, large demand and challenging production capacity.

The current situation of the special-purpose vehicle market

There is actually a paradox between the special-purpose vehicle and the general-purpose workshop. Dumpers can also be called special-purpose vehicles, but ordinary people naturally don't equate them with special-purpose vehicles because of their large demand and large inventory. Therefore, it is no problem to define whether a model is a special-purpose vehicle or a general-purpose vehicle by market ownership in some cases.

At present, Suizhou, as the special purpose vehicle capital of China, has nearly 2 special purpose vehicle manufacturers, including Hubei Chengli and Hubei Wuhuan. Most of them buy second-class chassis from mainstream OEMs such as FAW, Dongfeng and Shaanxi Automobile, and then sell them again.

according to different purposes, the price of special-purpose vehicles is also very different, which is basically the chassis price (roughly fixed)+equipment price (floating change) = total vehicle price, and the situation of the same model is much more expensive than that of ordinary models.

The medical vehicles mentioned above are also different from ordinary special vehicles. Because special medical equipment needs to be installed, the manufacturers need to sign relevant agreements with the national regulatory authorities before they can be sold.

In addition, except that negative pressure ambulances are mainly produced by manufacturers specializing in VAN models such as SAIC Datong, Jiangling Ford and Brilliance Group, there are many modification factories for the other three models.

although China's commercial vehicle market experienced a tragic decline of 9.94% year-on-year in 218, I believe that the future special purpose vehicle market will be paid more attention under the "fueling the fire" of this epidemic.

There are problems in China's medical logistics system

As a commercial vehicle media, medical logistics and medical vehicles are somewhat involved. I would like to express my personal views on the phenomenon revealed by this epidemic.

The epidemic has pushed the demand for all kinds of medical special-purpose vehicles to the peak, but the standard and quantity of special-purpose vehicles, the challenges and future development of special-purpose vehicles do not seem to attract much attention.

○? Negative-pressure ambulances donated by enterprises are sent to epidemic areas

It is not difficult to find that the reason for this situation is that China's pharmaceutical logistics started late and developed immature, and has always been in a subordinate position; The obvious reserve of medical vehicles also reflects the imbalance of the stock of commercial vehicles in China.

In view of these problems, if everyone is interested, my brother will have a chat alone, so that's all.

Write down at the end

Every difficulty is a kind of exercise for a person, so is it for a country? The commercial vehicle industry is not only cold and big, but we are also affectionate and righteous.
