With the development of time and technology, the car has long been into all households, people's understanding of the car is more and more deep. Because of this, many people for the general family car and even luxury cars, sports cars are like a treasure trove, not only can easily rely on local pictures to distinguish the brand model of the vehicle, and even more can be the age of the vehicle, design, related stories to tell.
However, we know a lot about ordinary cars, but how much do we know about utility vehicles? For example, in this epidemic as the "front" of the negative pressure ambulance, do you know enough about it? We know that the family car is divided into A class, B class, C class, then how many people know ambulances have what class? If you don't know the answers to these questions, then you may want to read on!
Q1: How are ambulances categorized?
There is a specific set of standards for ambulances in China, proposed by the Ministry of Health's Department of Medical Affairs, approved by the Ministry of Health of the People's Republic of China*** and the Ministry of Health of the People's Republic of China, and drafted by the Ministry of Health's International Emergency Rescue Center of the Ministry of Health's Center for International Exchange and Cooperation. This standard has a full 16 pages, the ambulance body size, the performance indicators, for ambulance classification, according to the classification of different ambulances with different rescue treatment configuration.
The ambulances can be categorized into four types: Type A (general), Type B (rescue and monitoring), Type C (protective and monitoring) and Type D (special purpose). In addition to the four body design, performance and ambulance configuration is different, the use is also different. Specific distinction is as follows:
From the above use distinction we can learn, in our daily life we see or contact with the ambulance type mostly for the first two, namely, type A and type B. The ambulance type is the most important type of ambulance in this epidemic. And the one that shines in this epidemic is the type C ambulance, also known as negative pressure monitoring ambulance. As for type D ambulances, we don't have much access to them, and they are generally used as emergency command vehicles and for transportation of supplies.
Q2: What are the differences between different types of ambulances?
As mentioned above, ambulance types are standardized in terms of body size, performance and configuration, so there are naturally big differences between them, so let's run through them briefly.
Type A ambulance
This type of ambulance is equipped with eight types of ambulance equipment, namely, patient handling equipment (such as a variety of stretchers), limb and upper spine immobilization equipment (such as splints and neck braces), supply/breathing equipment (such as oxygen cylinders), diagnostic equipment (such as blood pressure monitors, thermometers, flashlights, stethoscopes, and electrocardiographic monitoring equipment, etc.), circulatory equipment (such as infusion, syringe, infusion sets and infusion stands, etc.), bandaging and nursing equipment (e.g., wound care materials, vomit bags, sterile gloves, etc.), instrument kits (e.g., delivery kits, catheterization kits, debridement kits, and garbage cans, etc.), and communication equipment (e.g., wireless communication).
The above eight kinds of equipment can be called the standard configuration of the ambulance, the rest of the two types of ambulance type B and C equipment are added on this basis. And it is worth mentioning that the type A ambulance is considered a "high rate" of ambulance, but in some cities and towns, although there are also equipped with type A ambulance, but due to road congestion, often equipped with a number of light ambulances, mostly motorcycles and even bicycles converted to carry part of the equipment for emergency treatment, waiting for the subsequent arrival of the ambulance to take over.
Type B ambulances
These ambulances are equipped with all the medical equipment of type A ambulances, but on top of that, they also have pressurized infusion devices, chest decompression equipment, portable or multi-function ventilators, defibrillators, electrocardiographic monitors, and portable airway management systems.
Type C ambulance
This type of ambulance is the protagonist of the outbreak - the negative pressure ambulance. The reason why it has this alias is because of its added equipment, which adds to the Type B ambulance the Respiratory Infectious Disease Transport System equipment and appropriate cleaning and disinfecting materials. This system is able to create a low pressure so that air can only enter from the outside, while the air that is transferred out of the outside world from the inside is treated and sterilized to ensure that viruses do not spread further from the air. That's why the C-type ambulance is always there whenever there's a respiratory infection.
Q3: What do you know about ambulance "eggs"?
We all know that family cars have "colored eggs", but how much do you know about ambulance "colored eggs"? First of all, the national standard clearly states that the 0-100km/h acceleration time of the ambulance can not be greater than 25 seconds. For the family car, this is certainly an incredible figure, and from the current development of the car, this standard is undoubtedly not so applicable.
Secondly, the ambulance appearance design tone is also developed by the standard, the body should be marked with the Ministry of Health unified medical emergency vehicle standard "Star of Life", must be affixed with anti-gloss tape. Among them, the vehicle on the English word ambulance (ambulance) is actually reversed, due to the front of the car's rear-view mirror to see the mirror on the contrary, this design can be the first time to let the front vehicle from the rear-view mirror to determine the identity of the rear ambulance, the first time to get out of the way, to give way for the life of the channel.
Lastly, in the 1960s, the development of ambulances was not even emphasized, the ambulance was a car, the responsibility is only to transport patients from the scene of the accident to the hospital, the car is very narrow, equipped with the most basic first aid equipment, not only the ambulance staff to show their fists and feet, the ambulance equipment can be the first time to solve the urgent problem.
In fact, all kinds of ambulance, negative pressure ambulance technology content is undoubtedly higher, in similar to this epidemic in the role is relatively large. However, thanks to the domestic such as Datsun, Dongfeng, Jiangling outstanding independent brand car enterprises, whether they donated the negative pressure ambulance, or follow-up processing of additional vehicles, have played a positive role in the war epidemic, at the same time, we should also be proud of their own country's rapid development of automotive technology!
